Introduction: Coronary artery disease (CAD) is among the most common, serious, chronic and life- threatening illnesses in the world. CAD represents a spectrum of conditions, with acute myocardial infarction at one end of it and silent ischemia at the other. There is growing evidence on importance of prognosis of C- reactive protein (CPR) in unstable angina and this protein is a maker of an adve...

Introduction: Extreme weather or climate, including heat waves and cold waves, is considered a health issue causing adverse effects on health, such as cardiovascular diseases (CVDs), mortality and morbidity. Thus, this systematic review aimed to study the impacts of extreme ambient temperature on cardiovascular outcomes. Material and Methods: This study was carried out based on the Preferred R...

OBJECTIVES The aims of this study were: 1) to evaluate risk factors influencing the clinical course of mutation-confirmed adult patients with long QT syndrome (LQTS), 2) to study life-threatening cardiac events as a specific end point in adults, and 3) to examine the protective effect of beta-blocker therapy on cardiac events in adult LQTS patients with known cardiac channel mutations. BACKGR...

BACKGROUND Tiotropium is an anticholinergic bronchodilator for symptom relief and reducing exacerbations with an established safety profile in patients with chronic obstructive pulmonary disease (COPD). Using data from the 4-year Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT®) study, we re-evaluated the safety of tiotropium HandiHaler® in patients who experienced...

The aim of current study was evaluating the frequency of clopidogrel resistance and its impact on clinical outcome of patients in Iranian patients. Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who received standard dosage of clopidogrel (Plavix®, Sanofi, France, 600 mg loading dose and 75 mg/day afterward) were recruited. Platelet aggregat...

Several cases of cardiac adverse reactions related to vinorelbine (VNR) have been reported in the literature. In order to quantify the incidence of these cardiac events, we performed a meta-analysis of clinical trials comparing VNR with other chemotherapeutic agents in the treatment of various malignancies. Randomized clinical trials comparing VNR with other drugs in the treatment of cancer wer...

BACKGROUND AND OBJECTIVES Patients without previous history of cardiac disease can be regarded as low-risk when undergoing major non-cardiac surgery. The aim of this study was to examine whether preoperative B-type natriuretic peptide (BNP) level predicted postoperative cardiac events in these patients. SUBJECTS AND METHODS Preoperative BNP level was measured in 163 patients whose risk was co...

OBJECTIVE To assess the occurrence of cardiac events in patients diagnosed with left main coronary artery disease on diagnostic cardiac catheterization and waiting for myocardial revascularization surgery. METHODS All patients diagnosed with left main coronary artery disease (stenosis > or = 50%) consecutively identified on diagnostic cardiac catheterization during an 8-month period were sele...

BACKGROUND Non-invasive diagnosis and risk stratification of coronary artery disease are important for the selection and optimization of therapeutic interventions in diabetic patients, which may improve survival. The aim of this study was to determine the incremental value of contrast-enhanced dobutamine stress echocardiography (CE-DSE) for risk stratification. METHODS AND RESULTS CE-DSE was ...
