INTRODUCTION Patients with coronary diseases admitted to special care unit often suffer from sleep disorders, which may cause physiological changes and adversely affect patient's health. The relationship between sleep disorders and obesity is an important factor in studies on sleep disorders and other chronic diseases in all groups, including cardiovascular diseases. Understanding this relation...

Introduction Coronary flow reserve (CFR) is defined as a ratio of maximal (stimulated) to baseline (resting) coronary blood flow. CFR evaluation is important for the understanding of the pathophysiology of coronary circulation. CFR measurement is used both to assess epicardial coronary stenoses and to examine the integrity of microvascular circulation. An appreciation of coronary physiology is ...

Cardiovascular surgery had great advancement in the twentieth century. In 1929, Werner Forssman performed the first human cardiac catheterization on himself. Then cardiac catheterization gradually became a gold standard in the diagnosis of congenital heart diseases as well as valvular heart diseases. In 1953, Gibbon set a milestone for cardiac surgery by invention of cardiopulmonary bypass. Mas...

Uric acid, the end-product of purine metabolism in humans, is not only a cause gout, but also may play roles developing cardiovascular diseases such as hypertension, atrial fibrillation, chronic kidney disease, heart failure, coronary artery and death. Several clinical investigations have reported serum uric acid predictive marker for outcomes. Although causal relationship hyperuricemia to rema...

Isolated bilateral coronary artery ostial stenosis is a rare condition that has been associated with various diseases. We present the case of a 47-year-old male with bilateral coronary ostial stenosis. The patient's history was not significant for systemic diseases. The aorta had prominent signs of aortitis of unknown etiology, possibly due to a chronic mycotic process. The patient underwent em...

Background & Aims: Significant left main coronary artery disease (LMCAD) is found in 3 to 6 percent of all patients who undergo coronary arteriography. LMCAD usually requires an emergent surgery that has a higher rate of mortality and complications. The risk factors of left main involvement in previous studies are controversial. The aim of this study was to determine the traditional risk factor...
