Multi-frame X-ray images (videos) of the coronary arteries obtained using angiography (CAG) provide detailed information about anatomy and blood flow in play a pivotal role diagnosing treating ischemic heart disease. Deep learning has potential to quickly accurately quantify narrowings blockages from CAG videos. A consists videos acquired separately for left artery right (LCA RCA, respectively)...

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...

PURPOSE To evaluate the diagnostic performance of left coronary bifurcation angles and plaque characteristics for prediction of coronary stenosis by dual-source CT. METHODS 106 patients suspected of coronary artery disease undergoing both coronary computed tomography angiography (CCTA) and invasive coronary angiography (CAG) within three months were included. Left coronary bifurcation angles ...

A 68-year-old man underwent double-valve replacement (DVR) for active infective endocarditis caused by Enterococcus faecalis. Postoperative coronary angiography (CAG) revealed a saccular aneurysm originating from the distal portion of LMCA with severe stenosis at the ostium of the left anterior descending (LAD) artery and left circumflex artery (LCx). Emergent surgical resection with concomitan...
