https://journalca.com/index.php/CA/article/view/502
<p><strong>Introduction:</strong> Papillary fibroelastoma is a rare benign cardiac tumor, usually discovered incidentally or during evaluation for embolic events. Its echocardiographic appearance often mimics infective endocarditis, making diagnosis challenging.</p> <p><strong>Case Presentation:</strong> We report the case of an 83-year-old man with a history of hypertension and hypercholesterolemia, presenting with progressive dyspnea, orthopnea, and angina. Initial evaluation revealed elevated biomarkers and pulmonary edema. Transthoracic and transesophageal echocardiography showed a mobile mass attached to the posterior mitral leaflet, raising suspicion of infective endocarditis. However, blood cultures remained negative, and PET scan was inconclusive. The patient underwent surgical excision, and histopathological examination confirmed a papillary fibroelastoma. Postoperative evolution was favorable.</p> <p><strong>Conclusion: </strong>Papillary fibroelastoma should be considered in the differential diagnosis of valvular masses. Multimodal imaging is crucial, but histology remains the gold standard. Early surgical excision is recommended in symptomatic patients, even in advanced age, to prevent embolic complications.</p>SIYAM HamadyOBEIDAT SalehBOUCETTA AbdullahELFAKIHI ISMAIL.Pr DRIGHILHABOUB MiryemBOUZIANE Maha

<p>Alveolar hemorrhage (AH) is a rare yet severe clinical condition marked by significant bleeding into the alveolar spaces, often leading to high mortality. AH can occur following systemic thrombolysis for acute myocardial infarction (AMI), a complication that is infrequent but potentially life-threatening and may result in acute respiratory failure. This entity is rarely reported in the literature. This case report presents an instance of AH following intravenous thrombolysis for AMI in a 58-year-old male patient.</p>Vaishali GabaKalyan S.

2025-09-192025-09-19144121710.9734/ca/2025/v14i4504Postoperative Takotsubo Syndrome Presenting with Malignant Ventricular Arrhythmia: A Case Report
https://journalca.com/index.php/CA/article/view/506
<p><strong>Background:</strong> Takotsubo syndrome (TTS) is a stress-induced cardiomyopathy characterized by transient left ventricular systolic dysfunction, typically triggered by emotional or physical stress. While usually reversible, TTS can be complicated by severe events, with ventricular arrhythmias representing a particularly serious risk linked to increased morbidity and mortality.</p> <p><strong>Case Summary:</strong> We report a 63-year-old postmenopausal woman with hypertension and type 2 diabetes mellitus who underwent elective cholecystectomy under general anesthesia without intraoperative complications. Two days postoperatively, she developed persistent chest discomfort followed by sudden-onset palpitations. Electrocardiography revealed sustained monomorphic ventricular tachycardia at 180 bpm causing hemodynamic instability, which required urgent pharmacological and electrical intervention. Cardiac biomarkers showed a peak troponin of 1.2 ng/mL, and QTc was prolonged at 510 ms. Transthoracic echocardiography demonstrated a left ventricular ejection fraction (LVEF) nadir of 35%, and cardiac MRI confirmed apical ballooning and myocardial edema, consistent with TTS. The patient was stabilized with anti-arrhythmic therapy and beta-blockers, and discharged after seven days. At follow-up, LVEF normalized to 52%, troponin returned to baseline, and no arrhythmic events occurred.</p> <p><strong>Discussion:</strong> This case underscores the risk of malignant ventricular arrhythmias in TTS, particularly in the perioperative context where surgical stress can act as a trigger. The arrhythmogenic mechanism likely involved sympathetic overdrive, postoperative inflammatory responses, and repolarization abnormalities. Prompt recognition and timely management of arrhythmias are crucial to prevent life-threatening outcomes.</p> <p><strong>Conclusion:</strong> Although TTS is generally self-limiting, it can be complicated by potentially fatal ventricular arrhythmias. Clinicians should maintain a high index of suspicion in postmenopausal women presenting with acute chest pain or arrhythmia following recent surgery, as early diagnosis and intervention are essential to improving prognosis.</p>F.

https://journalca.com/index.php/CA/article/view/507
<p><strong>Background:</strong> Cardiac conduction disturbances are rare complications of diabetic ketoacidosis (DKA). They are usually transient and reversible with correction of metabolic abnormalities.</p> <p><strong>Case Presentation:</strong> We report the case of a 27-year-old woman with type 1 diabetes who presented with DKA and was found to have a complete atrioventricular block (AVB) on admission. Despite standard management with intravenous insulin, isotonic saline, and potassium replacement, the patient developed severe hypokalemia complicated by ventricular fibrillation and cardiac arrest. Resuscitation was successful, and metabolic abnormalities were corrected; however, the complete AVB persisted.</p> <p><strong>Outcome:</strong> A dual-chamber permanent pacemaker was implanted, with subsequent full recovery and discharge in stable condition.</p> <p><strong>Conclusion:</strong> This case highlights that AVB in the context of DKA may not always be reversible. Persistent conduction disturbances, particularly when complicated by malignant arrhythmias, require timely pacemaker implantation and individualized management.</p>F. ARABII. KATIFM. OUAZIZS.

https://journalca.com/index.php/CA/article/view/508
<p>Iatrogenic left main (LM) dissection is a rare but life-threatening complication of PCI that can result in abrupt occlusion of both LAD and LCX, especially when the LCX is dominant, leading to hemodynamic collapse and conduction disturbances such as complete heart block (CHB). We present the case of a 58-year-old male with evolving anterior wall MI who developed LM–LCX dissection during PCI, causing TIMI 0 flow in both LAD and a dominant LCX. Because the LAD supplied the largest myocardial territory, LM–LAD stenting was performed first to restore perfusion to the majority of myocardium, followed by bailout T-and-Protrusion (TAP) stenting of the dominant LCX with final kissing balloon inflation (FKBI) and proximal optimization technique (POT), achieving TIMI 3 flow in both branches. The patient recovered fully and was discharged on guideline-directed therapy. T-stenting was one of the earliest bifurcation techniques, and its refinement, TAP, allows optimal side branch ostial coverage with minimal metal overlap (7). Contemporary studies confirm that TAP, when performed with second-generation DES, FKBI, and POT, offers excellent outcomes comparable to more complex techniques such as DK-crush. This case highlights TAP as a rapid, effective, and lifesaving bailout strategy in LM bifurcation PCI, particularly when both branches are occluded but priority must be given to revascularizing the main branch supplying the largest myocardium.</p>Kalyan MundePrasad JainSamkit MuthaAnant MundeKhalil ShaikhVighnesh RaneAnil GuptaGaurav KothariVaishali Gaba

https://journalca.com/index.php/CA/article/view/509
<p style="margin: 0in; margin-bottom: .0001pt; text-align: justify; text-justify: inter-ideograph;"><span lang="EN-IN" style="font-size: 10.0pt; font-family: 'Arial',sans-serif;">We describe a 72-year-old female with chronic obstructive pulmonary disease (COPD), atrial fibrillation, and a large ostium secundum atrial septal defect (ASD), who presented with progressive dyspnea, hypoxemia, and acute COPD exacerbation. Despite advanced age, lung disease, arrhythmia, and a high surgical risk score, the defect was successfully closed percutaneously using a 46 mm Lifetech CERA device. ASD and COPD both have synergistic effect on Right heart volume overload leading to Right heart failure. This case demonstrates that transcatheter ASD closure can be safely and effectively performed in carefully selected elderly patients with significant left-to-right shunting and without Eisenmenger physiology, even in the presence of multiple comorbidities (1–3). Transcatheter ASD closure has less adverse events and faster recovery rates with reduction in duration of Hospital stay as compared to surgical closure. </span></p>Kalyan MundeRahul SonawaneSamkit MuthaAnant MundeRuchit ShahKhalil ShaikhJaykrishna NihariAnagh T SPrasad JainVaishali GabaDivya KantakSandip GhotiSuvarna ThoratDhanlaxmi Chettiar

https://journalca.com/index.php/CA/article/view/514
<p><strong>Background:</strong> The complete absence hepatic portion of the inferior vena cava (IVC) is known as “interruption” of the IVC. Congenital interruption of the IVC can rarely occur in patients with a normal visceroatrial situs. It is an uncommon vascular anomaly caused by failure in embryonic development. It can occur in isolation or in association with congenital heart defects.</p> <p><strong>Case Presentation:</strong> We report a 53-year-old man presenting with progressive dyspnea. Clinical examination revealed signs of right-sided heart failure. Electrocardiography demonstrated atrial fibrillation with a ventricular rate of 100 bpm. Transthoracic echocardiography showed type I Ebstein’s anomaly, severe tricuspid regurgitation, hypoplastic pulmonary artery with severe valvular stenosis, and IVC interruption. CT angiography confirmed agenesis of the middle and lower IVC segments with collateral drainage via the azygos and hemiazygos systems. The patient underwent successful surgical management consisting of bioprosthetic tricuspid valve replacement, pulmonary artery patch augmentation, and atrial septal defect closure.</p> <p><strong>Conclusion:</strong> This rare association of interrupted IVC and Ebstein’s anomaly highlights the importance of multimodality imaging in identifying complex cardiovascular malformations and guiding surgical planning</p>F.

2025-11-072025-11-071449510110.9734/ca/2025/v14i4514From Parasite to Plaque? Acute Myocardial Infarction in Severe Plasmodium vivax Malaria
https://journalca.com/index.php/CA/article/view/517
<p><strong>Background: </strong>Although <em>Plasmodium falciparum</em> is classically associated with severe malaria, <em>Plasmodium vivax</em>—once thought to cause only benign disease—is now recognized as capable of producing life-threatening complications, including acute respiratory distress syndrome (ARDS), renal failure, shock, and severe hematological abnormalities. Cardiac involvement in <em>P. vivax</em> infection is extremely uncommon, typically manifesting as myocarditis or conduction abnormalities. Acute ST-elevation myocardial infarction (STEMI) secondary to <em>P. vivax</em> infection is exceedingly rare, with only a few angiographically confirmed cases reported globally.</p> <p><strong>Case Presentation: </strong>We describe a 55-year-old female from Mumbai, India, who presented with high-grade fever, dyspnea, and hypotension. Peripheral smear confirmed <em>P. vivax</em> parasitemia. Laboratory evaluation revealed thrombocytopenia (22,000/µL), metabolic acidosis, and acute kidney injury. The patient developed ARDS requiring mechanical ventilation. Six hours after admission, she experienced acute chest pain, and ECG showed anterior wall STEMI with 4 mm ST elevation in leads V1–V5. Echocardiography demonstrated anterior wall hypokinesia with a left ventricular ejection fraction (LVEF) of 30–35%.</p> <p>After high-risk informed consent, intravenous streptokinase was administered, achieving >70% ST-segment resolution. Coronary angiography performed after stabilization showed a recanalized left anterior descending (LAD) artery with TIMI-3 flow and no residual stenosis. She was managed with artesunate, doxycycline, cautious dual antiplatelet therapy, and supportive care. The patient recovered completely and was discharged on day 12 in stable condition.</p> <p><strong>Discussion: </strong>This case illustrates a rare but serious cardiovascular manifestation of <em>P. vivax</em> malaria. Potential mechanisms include cytokine-mediated endothelial activation, coronary microvascular obstruction, catecholamine-induced vasospasm, and inflammatory endothelial injury. The concurrence of STEMI in <em>P. vivax</em> infection presents diagnostic and therapeutic challenges, especially in the presence of thrombocytopenia. Despite the bleeding risk, timely reperfusion was lifesaving.</p> <p><strong>Conclusion: </strong><em>P. vivax</em> malaria can no longer be regarded as benign. Clinicians in endemic areas should maintain a high index of suspicion for acute coronary events when ECG changes or chest discomfort occur in malaria patients. Angiographic documentation, early diagnosis, and prompt reperfusion therapy are crucial for improved outcomes.</p>Kalyan MundeSuvarna ThoratAnant MundeHariom KolapkarVighnesh RaneAnil Kumar GuptaSandip Ghoti

2025-11-122025-11-1214412913510.9734/ca/2025/v14i4517A Rare Dual Etiology of Gastropericardial Fistula in a Child: Gastric Malignancy with Candida Infection Leading to Pyopneumopericardium
https://journalca.com/index.php/CA/article/view/518
<p><strong>Background</strong><strong>:</strong> Pyopneumopericardium due to gastropericardial fistula with candida pericarditis is very uncommon in pediatric age group and with extremely high mortality. To the best of our knowledge this is the first case report of this kind in the pediatric literature.</p> <p><strong>Case Presentation:</strong> A 4 year old female child was referred from a pediatric tertiary care facility with history of fever, cough, fast breathing and subjected to pericardiocentesis in the referral centre in view of hydropneumopericardium with cardiac tamponade. Despite aggressive antibiotic administration and recurrent pericardial aspiration the general condition of the patient had a deteriorating course. The culture of candida in the pericardial fluid gave a clue to the presence of immunosuppression. She was diagnosed with candida pericarditis, persistent pneumopericardium secondary to gastropericardial fistula on account of gastric malignancy. She could not survive because of poor general condition on account of late and unusual presentation of gastric malignancy.</p> <p><strong>Conclusion: </strong>Non resolving pyopneumopericardium must always be investigated for candida pericarditis and its attendant cause of immunosuppression. Also an abnormal connection between the pericardial sac and any hollow viscera should be suspected. Early recognition and aggressive management will be life saving in such condition.</p>Pradeep Kumar JainVishwanath MohireNimish RaiKuber Sharma

https://journalca.com/index.php/CA/article/view/505
<p>Beta-blocker therapy remains a cornerstone of heart failure (HF) management, but its role in Asian populations is shaped by unique pharmacogenomic and economic factors. Registry data show prescription rates ranging from 61% in Indonesia to 91% in Japan, with consistently favorable outcomes despite markedly lower achieved doses compared to Western cohorts. Japanese patients, for example, attain equivalent survival and functional benefits at one-third of U.S. target doses, underscoring the need for region-specific dosing strategies. Across HF phenotypes, beta-blockers reduce mortality and hospitalization with no significant differences in adverse event rates among agents, and lower discontinuation rates in Asian cohorts suggest superior tolerability. Combination therapy with SGLT2 inhibitors, such as dapagliflozin, yields additive benefits, as efficacy persists regardless of background beta-blocker use. These findings support individualized therapy in Asia, highlighting the importance of integrating pharmacogenomics, health system capacity, and comorbidities into clinical decision-making.</p>Jonathan Kenigson

2025-09-242025-09-24144183010.9734/ca/2025/v14i4505Protecting the Diabetic Heart: Insights into the Cardiovascular Impact of DPP-4 Inhibitors
https://journalca.com/index.php/CA/article/view/513
<p>Diabetes poses a significant risk for cardiovascular disease. Clinical evidence, however, suggests that strict glycemic control does not decrease cardiovascular mortality, but rather increases it. This is partly because the majority of oral anti-diabetic medications have negative cardiovascular effects. For the treatment of type 2 diabetes, dipeptidyl peptidase-4 inhibitors are available as oral antidiabetic medications. This review focuses on the cardiovascular effects of DPP4 inhibitors. We utilised PubMed search engine, google Scholar to find relevant studies. DPP4 inhibitors, a new kind of oral anti-diabetic drug, have undergone several large-scale clinical studies to assess its cardiovascular safety. Incretin-based oral glucose-lowering medications known as dipeptidyl peptidase-4 inhibitors have been shown to be effective and safe for treating type 2 diabetes mellitus. Their metabolic impact is achieved by protecting incretin hormones such as glucagon-like peptide-1 from the breakdown of DPP-4. Several clinical studies are being conducted to assess the cardiovascular safety of DPP4 inhibitors. Three major prospective DPP4 inhibitor studies with cardiovascular outcomes were reported. Suggests Saxagliptin assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus (SAVOR-TIMI 53) and comprehensive patient-level pooled analysis with lingliptin versus standard comparator in patients with type 2 diabetes and CVD found that DPP4 inhibitors, such as saxagliptin and lingliptin, did not increase the risk of CV events in patients with type 2 diabetes and established CVD. DPP-4 inhibitors have been shown to lower numerous cardiovascular risk factors. Type-2 diabetes patients who are treated with DPP-4 inhibitors may experience cardiovascular benefits. But the risk of heart failure hospitalization remains a contentious issue, necessitating further multi-centre trials to establish the safety of DPP-4 inhibitors.</p>Srujana MDeeksha MSajan Francis PAghina Antony

2025-11-072025-11-07144859410.9734/ca/2025/v14i4513Cardiotoxicity of Targeted Therapies in Non-Hematologic Cancers: Mechanisms, Risks and Monitoring
https://journalca.com/index.php/CA/article/view/510
<p>Cardiotoxicity has emerged as an increasingly recognized concern in modern oncology, particularly with the growing use of targeted therapies such as small-molecule inhibitors and monoclonal antibodies. These agents have revolutionized cancer care by offering remarkable precision in selectively attacking molecular pathways essential for tumor growth and survival. However, despite their therapeutic benefits, targeted therapies may inadvertently affect the cardiovascular system, leading to adverse outcomes that can compromise both quality of life and long-term prognosis in cancer survivors. As cancer survival improves, the burden of treatment-related cardiovascular complications has become more evident, highlighting the need for early recognition, prevention, and management strategies.</p> <p>The mechanisms underlying cardiotoxicity from targeted therapies are highly complex and multifactorial. Unlike traditional chemotherapeutic agents, which often exert direct toxic effects on cardiomyocytes, targeted therapies may interfere with signaling pathways critical to both malignant and normal cardiovascular cellular functions. This disruption can manifest through a wide spectrum of adverse cardiovascular events, ranging from left ventricular dysfunction and arrhythmias to hypertension, thromboembolic events, and accelerated atherosclerosis. Importantly, these toxicities are often unpredictable and may vary according to the drug class, dosage, treatment duration, and patient profile.</p> <p>Risk factors for cardiotoxicity extend beyond the pharmacological properties of targeted therapies. Patient-specific characteristics—such as preexisting cardiovascular disease, age, sex, genetic predisposition, and concurrent exposure to other cardiotoxic agents—significantly modulate individual susceptibility. Moreover, the coexistence of traditional cardiovascular risk factors, including hypertension, diabetes, and dyslipidemia, may further exacerbate the incidence and severity of treatment-related complications. Identifying and stratifying patients according to these risk factors is therefore a crucial step in optimizing care.</p> <p>Given the rising incidence and clinical impact of treatment-related cardiotoxicity, effective management necessitates a multidisciplinary and integrated approach. Collaboration between oncologists, cardiologists, and emerging cardio-oncology units is essential to ensure timely detection and intervention. Regular cardiac monitoring, individualized risk assessment, and the prompt recognition of early warning signs form the cornerstone of preventive care. Furthermore, evidence-based strategies for mitigating cardiovascular risk ranging from lifestyle modification and optimization of comorbidities to pharmacological cardioprotection are increasingly being incorporated into clinical practice.</p> <p>In this review, we provide a focused overview of cardiotoxicity associated with targeted therapies, with particular emphasis on its underlying mechanisms, risk factors, and approaches to clinical management. By bridging oncology and cardiology perspectives, this work underscores the importance of proactive cardio-oncology collaboration to improve patient outcomes in the era of precision cancer medicine.</p>Rachida HabbalSafia OuarrakHind Dehbi

2025-10-112025-10-11144566110.9734/ca/2025/v14i4510Relationship between Apolipoproteins and Hypertension: Insights into the Pathophysiology of Hypertensive Disease
https://journalca.com/index.php/CA/article/view/511
<p><strong>Background:</strong> One of the most common cardiovascular conditions in the world, hypertension greatly increases morbidity and mortality. Its underlying biochemical and molecular factors are still not fully known despite a great deal of research. The pathophysiology of hypertension is becoming understood to be largely dependent on apolipoproteins, which are important regulators of lipid transport and arterial integrity.</p> <p><strong>Aim:</strong> To examine the connection between hypertension and apolipoproteins (ApoA-I and ApoB), clarifying their function in the etiology of hypertensive cardiovascular disease.</p> <p><strong>Methods:</strong> Participants with hypertension and normotension who were purposefully selected from a tertiary healthcare center participated in a cross-sectional study. The immunoturbidimetric test was used to quantify the serum levels of ApoA-I and ApoB, and normal clinical procedures were used to measure blood pressure and lipid parameters. An indicator of atherogenic risk was the ApoB/ApoA-I ratio. SPSS version 26 was used to analyze the data, and Pearson correlation and linear regression were used to find correlations between blood pressure, cholesterol indices, and apolipoprotein levels. The threshold for statistical significance was p < 0.05.</p> <p><strong>Results:</strong> ApoA-I levels were significantly lower (p < 0.05) and mean ApoB concentrations and ApoB/ApoA-I ratios were significantly greater (p < 0.001) in hypertensive participants than in normotensive controls. While ApoA-I exhibited inverse correlations (r = −0.52, p < 0.01) with systolic and diastolic blood pressures, ApoB exhibited positive correlations (r = 0.68 and 0.61, respectively). The ApoB/ApoA-I ratio was found to be an independent predictor of the severity of hypertension by regression analysis, which accounted for 46% of the observed variation in blood pressure.</p> <p><strong>Conclusion:</strong> The vascular dysfunction that underlies hypertension is largely caused by changes in the balance of apolipoproteins, specifically increased ApoB and decreased ApoA-I. In hypertensive populations, the ApoB/ApoA-I ratio is a better biomarker for evaluating cardiovascular risk.</p>Awosiku Femi FrancisBose Etaniamhe ORIMADEGUNAdesola Helen OniyeAdeyanju Funmilayo Victoria

<p>Cardiovascular diseases (CVDs) are the leading cause of death globally, with increasing prevalence in low- and middle-income countries, including Nigeria. Academic staff are often exposed to sedentary lifestyles and occupational stress, which may elevate their risk of developing CVDs. Understanding their knowledge and preventive practices is crucial for targeted interventions. This study assessed the knowledge of the types, risk factors, and preventive practices of cardiovascular diseases among academic staff of Abia State University, Uturu, Abia State, Nigeria. A descriptive cross-sectional study was conducted among 253 academic staff selected using a two-stage sampling technique. Simple random sampling was used to select seven faculties, while availability sampling was employed to recruit respondents. A structured, self-administered questionnaire was used to collect data. Descriptive statistics were used to analyse the results and were presented in tables. The majority of the respondents (58.1%) were male and within the 31–40 age group (36.8%). A high proportion (99.2%) had heard of CVDs, and 86.6% correctly identified a heart attack as a type of CVD. Knowledge of risk factors was high for smoking (99.6%), excessive alcohol intake (98.4%), and unhealthy diets (92.9%), while knowledge was lower for diabetes (6.7%) and obesity (4.0%). Preventive practices such as regular medical checkups were reported by 43.9%, while 54.5% monitored their blood pressure or cholesterol regularly. The internet and social media (53.0%) were the major sources of information, while only 22.1% had attended a health education programme on CVDs at their workplace. However, 78.7% expressed interest in attending future workshops or seminars on CVD prevention. While awareness of CVDs and their risk factors among academic staff was generally high, there were notable gaps in specific knowledge areas and preventive practices. Institutional health education interventions and workplace wellness programs are recommended to bridge these gaps and promote cardiovascular health.</p>UKA-KALU, EZINNE CHIOMAELEKEH, ROSEMARY ICHITAOKAFOR, KELECHI WILLIAMSOBISIKE VICTOR UGOCHUKWU

https://journalca.com/index.php/CA/article/view/515
<p><strong>Background:</strong> Myocardial infarction may go undetected as a catastrophic event leading to hemodynamic deterioration and sudden death. The role of cardiac makers in the prompt diagnosis of acute myocardial infarction AMI has been established especially in patient presenting with clinical features coronary artery disease, however, the use of known cardiac biomarkers in the risk assessment of MI in newly diagnosed patients with hypertension is unpopular. This study aimed to assess the risk for myocardial infarction using cardiac troponin I and Atherogenic indices in newly diagnosed drug naïve patients with hypertension.</p> <p><strong>Methods:</strong> The cross-sectional descriptive study was conducted among one hundred and seventeen subjects ≥18years. Anthropometric measurements and physical examination were done. Atherogenic indices for cardiovascular risk were estimated alongside biochemical parameters including cardiac Troponin I, lipid profiles, urea/creatinine and blood glucose. Data obtained were analysed using SPSS version 26, at <em>p </em><0.05.</p> <p><strong>Results:</strong> Most of the respondents were within the fourth decade of life, mean age of 45.24 ± 15.89 years. There was a preponderance for female sex with a male to female ratio of 1:1.2. Commonly reported clinical symptoms were palpitations, chest pain, shoulder pain and fatigue. The prevalence of cardiac troponin I (cTnI) was 10.3%, overall dyslipidaemia prevalence 97.4%, commonest was hypertriglyceridemia, and commonest pattern was mixed dyslipidaemia 70.2%. The majority with high cTnI had high CVD risk classified with AIP and CRR1. AIP demonstrated strong positive correlations with CRR1 <em>P</em><0.05. And cTnI is a strong predictor with good discrimination (AUC = 0.762) and balanced sensitivity (81.42%) and specificity (75%).</p> <p><strong>Conclusion:</strong> Cardiac troponin I showed good risk assessment value. The presence of cTnI activities clearly indicates an ongoing myocadiac structural changes, demonstrating a strong predictive strength. Also, AIP was identified as most important atherogenic index in drug naïve hypertensives.</p>Samson Aderemi OjedokunJoel Olufunminiyi AkandeAyobola Abolape Iyanda

https://journalca.com/index.php/CA/article/view/516
<p><strong>Objective:</strong> This study assessed the cardiac adaptation in elite Moroccan male and female football players using electrocardiography and echocardiography, with a focus on gender-specific similarities and differences.</p> <p><strong>Methods:</strong> Cross-sectional electrocardiography and echocardiography data from male and female athletes from football clubs in the Marrakech-Safi region, were collected at the Avicenna Military Hospital, Marrakech, during pre-competition assessments for Royal Moroccan Football Federation (RMFF) and FIFA competitions (2024-2025). Electrocardiography and echocardiography findings were interpreted according to international athlete-specific reference criteria.</p> <p><strong>Results:</strong> A total of 210 athletes were included (119 [56.1%] male; mean [SD] age, 22.5 [1.7] years). Female athletes showed a higher prevalence of normal training-related electrocardiography findings, while males displayed a slightly higher prevalence of mildly abnormal patterns (3.8% vs 2.8%, P < .001). Voltage criteria for left ventricular hypertrophy were present in 4.7% of males and 6.6% of females. No distinct electrocardiography abnormalities were detected. Echocardiography revealed no pathologic findings requiring restriction from sport, although some athletes exceeded ranges for exercise-induced remodeling defined in the guidelines. Increased left ventricular mass index was observed in 3 female athletes (3.1%) but in no males. Left ventricular wall thickness was normal in all athletes. Left ventricular cavity diameter >54 mm was observed in 6% of females, whereas no male athlete exceeded 60 mm. </p> <p><strong>Conclusions:</strong> Moroccan male and female football players exhibit limited electrocardiography and echocardiographic characteristics, consistent with physiological cardiac remodeling induced by intensive training. Accurate distinction between these benign adaptations and pathological findings is vital for reliable cardiovascular assessment and safe athletic performance.</p>Z. CHAIBOUKHES. NEHAMEJ. HAMIDA.
