PURPOSE Coronary artery calcium (CAC) is a specific indicator of and an independent risk factor for atherosclerosis; however, calcium scoring may miss noncalcified plaques, which may have clinical importance. The aim of this study was both to identify the presence and extent of coronary plaques during computed tomography coronary angiography (CTCA) in patients with a zero CAC score and to evalu...
background: there are some conflicting results with conventional coronary artery bypass grafts (ccabg) with arrested heart in coronary high-risk patients. moreover, performing off-pump cabg in these cases may be associated with serious complications. the objective of this study is to evaluate the efficacy of the on-pump beating cabg (opbcabg) in coronary high-risk patients in comparison with th...
Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...
For decades, many investigators have been trying to find the “factors” that increase risk of coronary artery disease , A lot cases reported for Asymptomatic patients or very mild symptoms and tendence be in cases, it could critical situation.
Direct noninvasive assessment of the characteristics of coronary atherosclerotic plaques is important to improve cardiovascular risk stratification and to monitor the course of coronary artery disease. Coronary computed tomography angiography (CCTA) has become an effective tool for noninvasive evaluation of coronary artery calcium and plaque components. Using CCTA, atherosclerotic plaques can b...
Calcium levels in the Coronary Artery are an indicative marker of presence and extent atherosclerosis. This serves as additional prognostic indicator addition to traditional risk factors. Moreover, coronary calcium test is associated with a descriptor known score or (Cs), which primarily useful for stratifying asymptomatic patients, while patients acute chronic chest pain, axial computed tomogr...
BACKGROUND The predictive value of coronary computed tomographic angiography (cCTA) in subjects without chest pain syndrome (CPS) has not been established. We investigated the prognostic value of coronary artery disease detection by cCTA and determined the incremental risk stratification benefit of cCTA findings compared with clinical risk factor scoring and coronary artery calcium scoring (CAC...
BACKGROUND Recent genome-wide association studies have identified 49 single nucleotide polymorphisms associated with clinical coronary artery disease. The mechanism by which these loci influence risk remains largely unclear. METHODS AND RESULTS We examined the association between a genetic risk score composed of high-risk alleles at the 49 single nucleotide polymorphisms and the degree of sub...
conclusions according to the results of the study, abdominal obesity is as a risk factor for atherosclerosis. therefore, the use of a simple, low cost and high precision method for determining visceral obesity and preventing the cad is warranted. background despite efforts made by the medical community and public health officials for combating 76 obesity, the prevalence of overweight and obesit...
Spontaneous coronary artery dissection is a rare cause of acute ischemic coronary events and sudden cardiac death. It usually occurs in young women without traditional risk factors for coronary artery disease during pregnancy or postpartum period. However, it has also been reported in patients with atherosclerotic coronary disease. We present a case of spontaneous right coronary artery dissecti...
