OBJECTIVES The purpose of this study was to determine the prevalence, clinical characteristics, and management of coronary chronic total occlusions (CTOs) in current practice. BACKGROUND There is little evidence in contemporary literature concerning the prevalence, clinical characteristics, and treatment decisions regarding patients who have coronary CTOs(More)
OBJECTIVE To assess nonarticular tenderness and prevalence of fibromyalgia syndrome (FMS) in hyperprolactinemic subjects. METHODS Twenty-one consecutive women with hyperprolactinemia (HPRL) and 44 consecutive women with normal prolactin levels (PRL) were examined in the fertility unit by one observer during a 24-month period. Mean age was 31 years, range(More)
Statins confer an antiplatelet effect in hypercholesterolemic subjects and in stable coronary artery disease patients. We explored the antiplatelet effects of statins in ST-elevation myocardial infarction (STEMI) patients undergoing primary angioplasty. Of 120 STEMI patients, 80 (67%) received statins while 40 (33%) did not. Ex vivo platelet reactivity was(More)
In patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), a patent infarct-related artery on initial angiography was associated with better angiographic results and improved prognosis compared with patients without spontaneous reflow. Little is known about the prevalence, clinical course, and(More)
BACKGROUND Stress-induced ST-segment elevation is an uncommon finding that usually occurs in patients with prior myocardial infarction (MI). Our purpose was to assess the angiographic and clinical significance of this finding in patients without prior MI. METHODS Of the 29002 consecutive ambulatory patients who underwent stress myocardial perfusion(More)
Although transcatheter aortic valve implantation (TAVI) for severe aortic stenosis is becoming an established technique, the impact of gender-related differences remains unclear. Two hundred twenty-four consecutive patients undergoing TAVI were prospectively followed up in a tertiary medical center. The primary end point of the present study was all-cause(More)
Unresponsiveness to clopidogrel or aspirin has been reported in patients with acute coronary syndrome (ACS). Platelet aggregometry (PA) and the Impact-R [Cone and Plate(let) Analyzer (CPA) technology, measuring whole blood platelet adhesion under flow conditions] were compared in detecting laboratory unresponsiveness to clopidogrel and aspirin among ACS(More)
Aspirin failure, defined as occurrence of an acute coronary syndrome despite aspirin use, has been associated with a higher cardiovascular risk profile and worse prognosis. Whether this phenomenon is a manifestation of patient characteristics or failure of adequate platelet inhibition by aspirin has never been studied. We evaluated 174 consecutive patients(More)
Cardiac computer models can help us understand and predict the propagation of excitation waves (i.e., action potential, AP) in healthy and pathologic hearts. Our broad aim is to develop accurate 3D MR image-based computer models of electrophysiology in large hearts (translatable to clinical applications) and to validate them experimentally. The specific(More)
We evaluated the effect and optimal dose of clopidogrel pretreatment in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (PPCI). The study included 383 consecutive patients with ST-elevation myocardial infarction who had undergone PPCI and were prospectively followed up for a prespecified primary end(More)
