OBJECTIVES We investigated the incidence, predictors, and prognosis of gastrointestinal bleeding (GIB) in patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). STUDY DESIGN We reviewed 2,541 consecutive patients (2,111 males, 430 females; mean age 56.5+/-11.8 years) who underwent primary PCI(More)
Aspirin is widely used for secondary prevention of cardiovascular disease, but is not effective for all patients. This phenomenon is called as aspirin resistance. Although the prognosis is worse in patients who develop acute coronary syndrome (ACS) while using aspirin, the frequency of aspirin resistance in these patients has not been evaluated. We aimed to(More)
We investigated sexual function in female patients with coronary artery disease (CAD). A total of 20 consecutive female patients (38.2±3.8 years) with CAD diagnosed by coronary angiography and 15 healthy subjects (37.9±5.4 years) were enrolled in this study. The Female Sexual Function Index (FSFI) was used to assess sexual function in all the participants.(More)
Systemic embolization is a potential complication in patients with thrombi situated in the left atrium and particularly, in the left atrial appendage (LAA). Reduced LAA contraction velocities, determined by the transesophageal echocardiography (TEE), are associated with increased risk of LAA spontaneous echocontrast and thrombus formation, and a history of(More)
OBJECTIVE The aim of this study is to compare the impact of two different loading conditions on myocardial contractility in asymptomatic patients with normal EF by using stain rate imaging (SRI). METHODS A total of 27 patients with severe aortic regurgitation (mean age 50 ± 11 years) and 25 patients with severe aortic stenosis (mean age 53 ± 15 years)(More)
BACKGROUND Bosentan improves symptoms in patients with Eisenmenger syndrome (ES). This study evaluated the effect of long-term bosentan therapy on cardiac function and its relation to symptomatic benefits in ES patients. METHODS AND RESULTS Twenty-three consecutive adult ES patients (15 with ventricular septal defect, 6 with atrial septal defect, and 2(More)
Exposure to toluene, one of the major components of glue, can lead to cardiac arrhythmias and sudden sniffing death syndrome. QT dispersion is a useful risk marker for cardiac arrhythmias and sudden cardiac death. The aim of this study was to investigate the effects of glue abuse on QT interval and QT dispersion. The study included 44 patients with inhalant(More)
OBJECTIVES We investigated mean platelet volume (MPV) in patients with slow coronary flow (SCF) and its possible relationship with clinical presentation. STUDY DESIGN The study included 50 patients with SCF and otherwise normal coronary arteries and 22 patients (control group) with normal coronary arteries. In the SCF group, there were 26 patients with(More)
The Myocardial performance index (MPI) is an echocardiographic index of combined systolic and diastolic function, calculated as isovolumetric relaxation time plus isovolumetric contraction time divided by ejection time. The aim of this study was to define the correlation of the MPI with plasma B-type natriuretic peptide (BNP) levels and echocardiographic(More)
