OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...

INTRODUCTION AND OBJECTIVES Although it has been demonstrated that the diagnostic accuracy of computed tomography in the non-invasive assessment of major epicardial coronary arteries is high, only a few studies have evaluated the technique's reliability in assessing coronary artery bypass grafts. The aim of this study was to determine the diagnostic accuracy of multidetector computed tomography...

Currently coronary artery bypass grafting (CABG) is the most commonly used procedure for revascularization of coronary heart disease. However it may not be suitable for the patients with diffuse coronary artery lesions, for which endarterectomy is a way but it’s not feasible to thin coronary artery without inner lumen or to the immature plaque. In this case, it may be a proper therapeutic optio...

One thousand women younger than age 50 years suspected of having coronary disease were followed for at least 5 years (average 8.4 years) to determine their course after coronary arteriography. Three patients were lost to follow-up; all had normal arteriograms. The survival rate was 96.9% at 5 years for 761 patients who had less than 50% narrowing of any artery. One patient who had coronary ecta...

apical ballooning syndrome (abs) is a reversible cardiomyopathy with presentation mimicking an acute coronary syndrome. so in clinical practice, it is essential to consider it in the differential diagnosis of patients presenting with chest pain, especially in postmenopausal women. coronary angiography is usually indicated to achieve a proper diagnosis. typically, patients do not have significan...

BACKGROUND To define and evaluate coronary contrast opacification gradients using prospectively ECG-gated single heart beat 320-detector row coronary angiography (CTA). METHODS AND RESULTS Thirty-six patients with normal coronary arteries determined by 320 x 0.5-mm detector row coronary CTA were retrospectively evaluated with customized image postprocessing software to measure Hounsfield Unit...

he extent of coronary artery narrowing has been considered a primary and readily available determinant of survival in patients with coronary artery disease. Despite continuous refinement in antithrombotic therapy and intracoronary stents, the extent and complexity of coronary artery disease remain major determinants of shortand longterm prognosis in patients undergoing percutaneous coronary int...

BACKGROUND Coronary sequelae that persist after Kawasaki disease (KD) have been associated with obstructive changes of the lesions and coronary vascular events in adolescents and young adults. However, little is known about the association between sequelae late after KD and inflammatory markers, which are potential mediators and markers for atherogenesis. METHODS AND RESULTS Cross-sectional s...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

A 57 year-old man, obese, with history of hypertension, dyslipidemia, smoking and two previous ischemic strokes, was admitted with a six month history of chest pain associated with dyspnea on moderate and large efforts. He was hemodynamically stable and making use of captopril, aspirin, hydrochlorothiazide and metroprolol. There was no mention of chest murmur in the hospital admission record. A...
