چکیده
Beller et al. showed in the “anginal cascade”(1) that, with increasing stress time and myocardial oxygen demand, ischemic ST depression and anginal symptoms appear after fl ow heterogeneity, regional myocardial dysfunction, signifi cant perfusion defects and global left ventricular dysfunction. This accounts for the increased sensitivity, specifi city and accuracy of MPI over symptoms and stress ECG in the diagnosis and follow-up of coronary artery disease.

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 ho...
متن کاملCoronary artery calcium (CAC) score – a prognostic tool in coronary artery disease?
Introduction: The aim of this study was to evaluate the impact of measurement of coronary artery calcification score (CAC) in patients with suspected coronary artery disease (CAD) and a normal myocardial perfusion scan. Methods: In a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of CAD and a normal perfusion scan. In ...
متن کاملMyocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]
Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...
متن کاملThe association between NFKB1 -94ATTG ins/del and NFKB1A -826C/T genetic variations and coronary artery disease risk
Coronary artery disease (CAD) is considered as a chronic inflammatory disease initiated from early childhood. Nuclear factor κB (NF κB) and κB1A (NF κB1A) are the key regulators of inflammatory responses. The NFKB1 -94ATTG ins/del and NFKB1A -826C/T polymorphisms may contribute to the development of CAD. The aim of the present study was to investigate the association of these polymorphisms wit...
متن کاملRelationship between the location of the most severe myocardial perfusion defects, the most severe coronary artery stenosis and the site of subsequent myocardial infarction [Persian]
This study evaluated the relationship between the location of the most severe coronary artery stenosis and the subsequent acute myocardial infarction (AMI). Methods: Of 1590 patients who were admitted with a diagnosis of AMI, we identified 44 patients who had undergone previous myocardial perfusion SPECT. Thirty-one of these patients also had previous coronary angiography. The relationshi...
