Coronary artery anomalies occur in 1.3-5.6% of patients undergoing coronary arteriography. An anomalous origin of LCX from right coronary sinus is the most common congenital variant. It is usually considered “benign” since it is not known to predispose individuals to sudden cardiac death. Such vessels are particularly predisposed to atherosclerotic disease in their proximal portion, due to the acute angulation of its origin from the aorta and its posterior retro aortic course. We present a case of 55 years old female admitted with acute coronary syndrome. Coronary angiogram showed the anomalous origin of the left circumflex artery from right coronary sinus. This artery had a significant lesion which was successfully stented with a drug-eluting stent.

Arrhythmias can complicate the course of patients with ST-elevation myocardial infarction. These arrhythmias can include both tachyarrhythmias and bradyarrhythmias. Tachyarrhythmias range from Ventricular premature complexes to life-threatening ventricular tachycardia/ fibrillation. Bradyarrhythmias range from sinus bradycardia to complete heart block. These arrhythmias have the ability to provoke hemodynamic consequences and increase mortality. Tachyarrhythmias are more common with Anterior wall myocardial infarction and bradyarrhythmias are more common with Inferior wall myocardial infarction. We report a case of Mobitz Type 1 (Wenkebach) second-degree atrioventricular block in a patient with Anterior wall myocardial infarction. Angiography showed a significant lesion in Left anterior descending artery, after the first septal and diagonal branch. After the successful percutaneous coronary intervention, this second degree AV block reverted to first degree AV block. To the best of our knowledge, there is no case report describing this association separately.

Aim: Atherosclerotic renal artery stenosis is one of the main causes of secondary hypertension and results in a progressive loss of renal function. This case reports recurrent hypertensive pulmonary edema and worsening renal function successfully treated with multiple percutaneous renal interventions.

Presentation of the Case: A 62-year-old female patient was admitted for carotid endarterectomy. She had uncontrolled blood pressure and worsened renal function. Bilateral renal artery stenosis was diagnosed and endovascular procedure plus stent was performed in both renal arteries. She was discharged with an improvement in renal function and blood pressure. Three months later, she presented a sudden onset of pulmonary hypertensive edema. Renal arteriography confirmed bilateral in-stent restenosis and a new bilateral angioplasty plus stent was fulfilled. Six months later, new worsening of dyspnea, severe renal dysfunction, and new hospitalization were indicated renal replacement therapy. Renal arteriography showed again bilateral renal artery in-stent restenosis and bilateral balloon catheter angioplasty with no stent was performed. She was discharged, with no need for hemodialysis, improved blood pressure and proposal for further discussion about surgical revascularization.

Discussion: When severe reduction of glomerular filtration rate occurs in hypertensive patients with high risk for atherosclerotic disease, it seems prudent to examine renal arteries. Once a diagnosis is made, if blood pressure control cannot be achieved, mainly associated with progressive renal dysfunction, it is recommended restoration of renovascular supply.

Conclusion: Percutaneous renal intervention with no-stenting in bilateral in-stent restenosis and recent onset of hemodialysis may contribute to reversion of renal dysfunction even in patients undergoing to previous interventions.

Background: It is reported that 20 to 30% of patients are not responders to this treatment (Cardiac Resynchronization Therapy). The reasoning in this merely theoretical paper shows the plausible danger that can be brought by measurements apparatus, in the occurrence the CRT especially when it is sophisticated.

Objective: In Physical Cardiochemistry field our overall purpose is to bring a contribution to heart health. It is needful to draw attention for caregivers and manufacturers, especially with respect to the magnetism these apparatuses may exhibit.

Methods: The Observation and documentary research are used. It is recalled hereby successively energy metabolism in healthy cardiomyocyte, adaptive energy metabolism of a hypertrophied and insufficient heart, cardiac resynchronization therapy and energy metabolism of the cardiomyocyte with its potential effects on both glucose oxidation and fatty acids oxidation.

Results: It is shown a plausible interaction between oxygen magnetic field, paramagnetic by nature, and pacemaker and/or defibrillator electromagnetic field according to the sacral principle of “like dissolves like” with all evil consequences on patients.

Conclusion: It will be necessary to evaluate later not only the behavior of the various energetic substrates of a hypertrophied heart as a function of the variation of the magnetic field strength but also the content of the probable substances produced in the presence of a magnetic field and with a potentially harmful effect on cardiac function. Convinced technology has its setbacks, the pacemakers and/or defibrillators manufacturers are invited to a greater rigor, greater caution and sustained care in building these devices. In next publication study of a case (CRT-D), where the diabetes has been observed, will be outlined.

Angiotensin 1-7: A Second Window of Protection in Hypertensive Patients

The effects of the renin-angiotensin-aldosterone system on the human body are so diverse and our knowledge about them is ever growing. Angiotensin 1-7 has been proven to play protective roles in patients with cardiovascular disorders including but not limited to hypertension.

As is the case with Africa, the prevalence of hypertension in Sudan is rising, and its complications could be delayed by pharmacologically manipulating the levels of renin-angiotensin system metabolites.

The aim of this review is to compare the advantageous and deleterious effects of Angiotensin 2 in contrast to those of Angiotensin 1-7 and to assert the well-established protective effects of Angiotensin 1-7 (systemically and locally) in hypertensive patients
