BACKGROUND As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative for evaluation of coronary anatomy with a lower referral threshold than invasive coronary angiography (ICA), the prevalence of coronary anomalies in CCTA may more closely reflect the true prevalence in the general population. Morphological features of coronary anomalies can be evaluated more ...

background: the existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (cad). however, the results of the studies conducted hitherto on this subject are inconsistent. we sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of cad in patients undergoing n...

background and objective: obstructive sleep apnea (osa) is frequent and in some degree it affects about 24% of male and 9% of female in middle age adults. this study aimed to assess the association between risk of osa and cad. materials and methods : this case-control study was performed among 184 patients with a history of coro- nary angiography in two catheter labs at hospitals in qom, iran. ...

background: coronary angiography, albeit a safe procedure, may cause serious complications especially in patients with left main stenosis (lms). this study was designed to investigate the efficacy of workload achieved by exercise tolerance test (ett) in predicting lms in candidates for coronary angiography. methods: a total of 743 patients with a positive ett who subsequently underwent cardiac ...

conclusions the pattern and number of vessels involved were similar in both groups. based on common prevalence of traditional risk factors among two groups, planning for lifestyle changes is recommended. results of the 112 patients, 51 (45.5%) were in group a and 61 (54.5%) were in group b with mean age of 37.6 ± 4.4 and 63 ± 8.5, respectively. no significant statistical differences were found ...

conclusions the scf phenomenon is relatively frequent, particularly among patients with acute coronary syndrome who are scheduled for coronary angiography. hypertension, a low hdl-c level, and high hemoglobin level can be considered independent predictors of this phenomenon. results among the 3600 patients scheduled for selective coronary angiography, 75 (2%) met the scf criteria. scf and neca ...

conclusions our findings revealed that the severity of coronary artery stenosis is common in diabetic patients compared to nondiabetics. early diagnosis and treatment of cad in diabetic patients is recommended. results based on data found in our study, 93.8% of diabetic and 83.4% of nondiabetic patients were shown to suffer coronary artery stenosis. severe involvement (grade 3vd) of coronary ar...

Objectives Coronary artery anomalies are uncommon, but important cardiac malformations, representing the second commonest cause of death in young athletes. Methods We utilized computerized tomographic angiography to screen and precisely delineate coronary artery anomalies in patients with minimal cardiac symptoms. Results During 3.5-year period, we performed 2888 computerized tomographic an...

The purpose of this study was to investigate the value of a respiratory-gated three-dimensional (3D) magnetic resonance angiographic technique (MRCA) in identifying coronary arteries in healthy volunteers and patients with proximal coronary artery stenoses and to compare the results of the navigator echo technique in the assessment of coronary artery stenosis with conventional coronary angiogra...

BACKGROUND A normal anatomy of coronary arteries is important to have adequate cardiac muscle blood supply especially during extraneous physical activities. This case report describes a rare coronary anomaly in which the accessory coronary artery arose from the right coronary artery, reentered the left anterior descending coronary artery, and then ran as a single vessel. CASE PRESENTATION We ...
