objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

introduction: coronary endarterectomy is not a perfect procedure. however, it is sometimes the only available alternative for cardiac surgeons in patients suffering from diffuse coronary artery disease. according to a large volume of studies, coronary endarterectomy results (such as survival, recurrence of the symptoms of myocardial ischemia, and graft patency) are not as satisfactory as standa...

introduction: aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. the purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients hosp...

UNLABELLED In type 2 diabetes mellitus (DM2) patients, coronary artery disease (CAD) generally is detected in an advanced stage, whereas an asymptomatic stage is commonly missed. Abnormal myocardial perfusion during stress myocardial contrast echocardiography (MCE) and significant CAD were similar, irrespective of risk factor (RF) profile in our patients, but coronary anatomy differed. An "aggr...

background: systolic blood pressure recovery (rsbp) is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (cad). this study investigated the association between rsbp and exercise indices after complete cardiac rehabilitation program (cr) in a population-based sample of patients undergoing coronary artery bypass grafting (cabg). methods...

Coronary anatomy has traditionally focused on ventricular circulation. This is largely due to the extent to which coronary artery disease contributes to ischemic heart disease through ventricular myocardial damage. Atrial fibrillation and other tachyarrhythmias that involve the atria, however, remain a major cause of morbidity and mortality. In order to increase mechanistic research and therape...

We describe a patient with an infrequent combination of variants in both the right and the left coronary arterial ostia, namely a combination of two separate right coronary artery (RCA) ostia from the aorta, and an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). To our knowledge, such a combination has not been previously reported. Based on published statistics ...

Exercise 201Tl SPECT imaging has become routinely accepted and utilized as a major screening test for atherosclerotic coronary artery disease. In appropriate clinical situations, an abnormal 201Tl study usually will require a subsequent coronary angiogram to confirm the presence of an abnormality and to define its pathologic anatomy. Although most reversible thallium defects will prove to be se...

this article describes coronary artery bypass grafting by avlliath jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. the aim of coronary artery bypass grafting is to release pain, prevention of myocardial inf...
