Risk Factors in Patients with Non-ST Segment Elevation Myocardial Infarction.

Introduction: The most common cause of myocardial ischemia is atherosclerotic epicardial coronary artery disease, present in 90% of patients. Risk factors positively correlate with the onset, development and subsequent complications of atherosclerotic disease.

Aim: Determine the percentage frequency of classic risk factors for coronary disease in patients with non-ST segment elevation myocardial infarction (NSTEMI), with regard to gender.

The role of exercise test in stratifying the risk of asymptomatic patients with moderate/severe aortic stenosis.

Objectives: The role of exercise test in risk stratifying of asymptomatic patients with moderate and severe aortic stenosis (AS) in recent literature is still controversial. The aim of this study was to evaluate the role of exercise test in stratifying the risk of patients with moderate to severe aortic stenosis.

Methods: At the Internal Medicine Clinic, Department of Cardiology in Tuzla, in the period from January 2008 until January 2010 was followed 33 patients with clinical and echocardiographic parameters of moderate to severe asymptomatic aortic stenosis (mean effective orifice area EOA 0.
