The relation between lipoprotein(a) [Lp(a)] as an independent risk factor for coronary atherosclerosis and the severity and extension of angiographically detectable coronary atherosclerotic lesions has not been systematically evaluated. In 118 male patients (54.3 +/- 7.4 years) with suspected coronary artery disease and without a history of myocardial infarction undergoing coronary angiography,...

BACKGROUND Computed tomography angiography enables non-invasive evaluation of the coronary arteries. OBJECTIVES To evaluate the accuracy of 16-slice multi-detector CT angiography in the diagnosis of coronary artery disease, and assess coronary bypass grafts and coronary anomalies. METHODS We conducted a retrospective study of 223 patients who were examined at our medical center over a perio...

background: isolated right bundle branch block (rbbb) is a common finding in the general population. the atrioventricular node (avn) artery contributes to the blood supply of the right bundle branch. our hypothesis was that the anatomy of the avn artery and the pattern of dominancy differ between subjects with and without rbbb. methods: w e retrospectively studied the coronary angiography of 92...

S pontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndromes (ACS), typically affecting female and younger individuals with no underlying atherosclerotic disease. 1 Diagnosis of SCAD has traditionally relied on coronary angiography; however, new imaging modalities, and especially optical coherence tomography (OCT), improve diagnostic accuracy and help management. 2...

Purpose: To assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in Cardiac Magnetic Resonance of patients with history of remote myocardial infarction. Materials and Methods: The Cardiac Magnetic Resonance images of sixty patients with history of remote ST segment or non-ST segment elevation myocardial infarction were ...

background :in addition to diagnosing the acute myocardial infarction (mi), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting mi. many studies have been conducted to predict the occlusion site by interpreting the st segment deviations in electrocardiogram (ecg).additional posterior and right precordi...

background although the aim of cardiac computed tomographic angiography (cta) is to visualize the cardiac, coronary, and great vessels, portions of noncardiac structures such as lung, mediastinum, bones and abdomen are visible on the scan. some have suggested that the scans should be evaluated in all field of view. some other believe that reporting accidental findings can lead to unnecessary fo...

OBJECTIVES The aim of this study was to compare outcomes and coronary angiographic findings in post–cardiac arrest patients with and without ST-segment elevation myocardial infarction (STEMI). BACKGROUND The 2013 STEMI guidelines recommend performing immediate angiography in resuscitated patients whose initial electrocardiogram shows STEMI. The optimal approach for thosewithout STEMI post–cardi...

to study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (cad), a study has been designed to compare this feature between patients having stable angina (sa) or unstable angina (ua) who underwent coronary angiography in tehran heart institute. study objectives were detection of the angina producing artery (ap a) and its morphologic lesion type, de...

B of the coronary arteries may vary in origin, distribution, number, and size. Congenital anomalies of the coronary arteries occur in 0.2-1.2% of the general population.1 Most coronary artery anomalies do not cause myocardial ischemia and are often found incidentally during angiographic evaluation for other cardiac diseases. These pathologic anomalies may be present from early infancy and can r...
