background: myocardial ischemia is one of several causes of prolonged qt dispersion. the aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina. methods: we assessed the effects of full revascularization in patients with chronic stable angin...

coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...

Percutaneous coronary intervention in the setting of coronary bifurcation lesions is associated with increased risk for complications. The goal of this manuscript is to review the currently available classifications for coronary artery bifurcation lesions with a guide to the use of specific coronary bifurcation techniques based on lesion characteristics

coronary artery perforation is a rare, but potentially serious, complication of percutaneous coronary intervention and is associated with a high incidence of death, q-wave myocardial infarction, and emergency coronary bypass surgery. management is different but requires prompt recognition and treatment. we describe a case of coronary perforation only after guidewire removal and also review the ...

several studies have reported that the antioxidant properties of melatonin can provide cardiac protection through scavenging of free radicals. this study sought to investigate the efficacy of melatonin on cardiac biomarkers, myocardial-specific protein high sensitive troponin-t (hs-tnt) and creatine kinase-mb (ck-mb), in patients with st-segment elevation myocardial infarction (stemi) undergoin...

AIMS Although hirudin is superior to unfractionated heparin for prevention of death, myocardial infarction, or refractory ischaemia in patients with non-ST-elevation acute coronary syndrome, it is not clear whether hirudin is also of benefit in acute coronary syndrome patients undergoing early percutaneous coronary intervention. METHODS AND RESULTS In the OASIS 2 trial, 10 141 patients with n...

Background: This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention.Material and Methods: Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were r...

background: combination antiplatelet therapy is a classic treatment for percutaneous coronary intervention (pci) but this therapy increases gastrointestinal bleeding (gib). this study highlights the incidence of related risk factors of gib and endoscopic findings in patients with gib after pci and combination antiplatelet therapy. materials and methods: a standard check list was used to evaluat...
