Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

background: coronary disease is the most common cause of death in the world. because of common risk factors, atherosclerotic stenosis of coronary and carotid arteries occurs together. this study evaluated the prevalence of carotid stenosis in diabetic candidates for angiography methods: in a cross-sectional study, 152 diabetic candidates for angiography referred to cardiology clinic of shariati...

Coronary arteriosystemic fistula which drains into the left ventricular cavity is a rare congenital anomaly. A case of double fistulae between the left anterior descending and left circumflex coronary arteries and left ventricular cavity is presented. The patient's chief complaint, chest pain, was attributable to the "steal phenomenon."

Ephedrine, metaraminol, epinephrine and maneuvers like carotid sinus stimulation used during intraoperative period have been postulated to cause temporary spasm of the coronary vessels leading decrease supply myocardium precipitating myocardial infraction in non-obstructive arteries (MINOCA). As an anaesthesiologists, we should be aware that even a dose as small 25 mcg infiltrated along with lo...

Cardiac adversity is by far the commonest cause of mortality in patients with diabetes.to study angiographic extents, number coronary vessels, and type lesions(A, B, C)and comparison findings between diabetic nondiabetic patients. The included all Syrian who underwent a cardiac catheterization from 8 March to September 2022 at Tishreen University Hospital Latakia. It 455 patients; 181 them wer...

survey of anatomic variations of coronary arteries is the most fundamental of researches in the field of these vessels. for performing this survey, coronary arteries (ca's) of 463 human heart cases (gathered from three different surces: 1) legal medicine center corpses, 2) cadavers of dissection rooms in medical schools, and 3) ca's angiographic films from hospital centers) were studi...

Regional differences of the responses to adrenoceptor agonists were investigated in isolated canine coronary arteries by use of a cannula inserting method. Acetylcholine induced a dose-dependent vasodilation. Norepinephrine and epinephrine produced a vasoconstriction followed by a strong vasodilation in large coronary arteries and only a weak vasodilation in small coronary arteries. Phenylephri...
