Contrast-enhanced multi-detector row spiral computed tomography (MDCT) was introduced as a promising noninvasive method for vascular imaging. This study examined the accuracy of this technique for detecting significant coronary artery stenoses. Both MDCT(Sensation 16, Siemens, Germany, 12x0.75 mm collimation and 0.42 sec rotation speed, 120 kV, 500 effective mA, and 2.7 mm/rotation table-feed) ...

BACKGROUND The gold standard test for the diagnosis of coronary artery disease (CAD) is conventional coronary angiography (C-CAG). Lately, multislice computed tomographic coronary angiography (MSCT-CAG) demonstrated a high sensitivity and a negative predictive value for a CAD primary diagnosis when compared with C-CAG. The aim of our study is to prospectively assess the safety of ruling out CAD...

Coronary angiography (CAG) is the conventional procedure, considered gold standard for examination of coronary arteries. Being a standardised CAG comparatively safer but an invasive procedure. Therefore, it carries some amount risk compared to computed tomography (CTA). CTA new technique non-invasive and reported be as or more accurate efficient functional stress test in diagnosis CAD comparabl...

OBJECTIVE Anatomic coronary artery disease (CAD) can be determined by coronary angiography (CAG) in patients with normal stress single photon emission tomography (SPET) myocardial perfusion imaging (MPI). Coronary angiography results of patients with negative exercise MPI and the prognosis of these patients (CAG-diagnosed CAD vs. non-CAD) were investigated in the current study. SUBJECTS AND M...

BACKGROUND Permanent coronary artery damage is a hazardous complication of epicardial radiofrequency ablation. Irreversible electroporation (IRE) is a promising nonthermal ablation modality able to create deep myocardial lesions. We investigated the effects of epicardial IRE on luminal coronary artery diameter and lesion depth. METHODS AND RESULTS In 5 pigs (60-75 kg), the pericardium was exp...

a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...

Coronary embolism is an uncommon cause of myocardial infarction. A 48-year-old male presented with typical chest pain of an MI. There was no definite ST segment change on electrocardiogram (ECG) and no elevation of myocardial enzymes. Coronary angiography (CAG) revealed occlusion of the distal left anterior descending coronary artery (dLAD), the distal left circumflex coronary artery (dLCX), th...

In this case report, we present a of 38-year-old woman with no cardiac history and risk factors who was admitted to the hospital spontaneous coronary artery dissection (SCAD) after pregnancy. Twelve years later, she suffered recurrent SCAD during her menopause. is rare occurrence acute syndromes recurrence even more rare. seems occur predominantly in females be related hormone levels. At first ...

OBJECTIVE Plasma osteoprotegerin (P-OPG) is an independent predictor of cardiovascular disease in diabetic and other populations. OPG is a bone-related glycopeptide produced by vascular smooth muscle cells and increased P-OPG may reflect arterial damage. We investigated the correlation between P-OPG and coronary artery disease (CAD) in asymptomatic type 2 diabetic patients with microalbuminuria...
