Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

The prevalence of anomalous coronary artery is approximately 0.6-1.7% in patients who undergo coronary angiography. These anomalies may cause angina, acute myocardial infarction, syncope and sudden death. Cocaine abuse is now a major health hazard: more than 5 million of Americans are current users. Cocaine abuse can result in coronary artery vasocostriction and the association between cocaine ...

Coronary artery anomalies are found in 0.6% to 1.55% of patients who undergo coronary artery radiographic tomography [1-5] and the increasing use of diagnostic coronary angiography (CAG) is uncovering even more such abnormalities. Anomalous origin of the left main coronary artery (LMCA) from the right sinus of Valsalva is reported in 0.09% to 0.15% of cases [1-6]. Indeed, most coronary anomalie...

Anomalous left coronary artery arising from the pulmonary artery (ALCAPA) is a rare but very serious congenital coronary artery anomaly. Multidetector computed tomography (MDCT) coronary angiography has recently become the gold standard for depicting anatomical variations and anomalies of the coronary arteries because the origin and course of anomalous arteries can be demonstrated very accurate...

background : st-elevation myocardial infarction (stemi) is a major cause of cardiovascular mortality worldwide. there are differences between very young patients with stemi and their older counterparts.   this study investigates the demographics and clinical findings in very young patients with stemi. methods: through a review of the angiography registry, 108 patients aged ≤ 35 years (group i) ...

Introduction Coronary artery fistulas (CAF) are congenital or acquired formations between the coronary arteries and cardiac chambers or other vascular structures such as the vena cava, pulmonary artery, or veins [1]. Most of these are found incidentally during angiography [2]. Fistulas account for half of all coronary anomalies and are present in 0.002% of the general population. Coronary to pu...

BACKGROUND Congenital coronary anomalies are uncommon with an incidence ranging from 0.17 % in autopsy cases to 1.2 % in angiographically evaluated cases. The recent development of ECG-gated multi-detector row computed tomography (MDCT) coronary angiography allows accurate and noninvasive depiction of coronary artery anomalies. METHODS This retrospective study included 2572 patients who under...
