Troponin release following exercise test in patients with stable angina pectoris - risk factors and prognostic significance.

Background: Increase of troponin (cTn) is a marker of myocardial injury caused by different mechanisms. Exercise testing (ExT) is a useful clinical tool in predicting the risk of myocardial ischemia, especially in patients with multivessel coronary artery disease (CAD), who are more often endangered by medical complications. The test is however limited by its low sensitivity and specificity.

[Echocardiography and tissue Doppler imaging in assessment of haemodynamics in patients with idiopathic, premature ventricular complexes].

Unlabelled: Premature ventricular complexes (PVC) in patients without organic heart disease may be associated with severe symptoms and haemodynamic disturbances. The aim of this study was to evaluate haemodynamics during PVC by echocardiography (ECHO) and tissue Doppler imaging (TDI).

Material And Methods: 40 consecutive patients (mean age 55 +/- 15) with frequent, idiopathic PVC were included into analysis.

Magnitude of and risk factors for in-hospital and postdischarge stroke in patients with acute coronary syndromes: findings from a Global Registry of Acute Coronary Events.

Background: Stroke is a recognized complication after acute myocardial infarction, but few studies have investigated the incidence and outcome of stroke in patients with acute coronary syndrome (ACS). This study examined the incidence and outcomes of hemorrhagic and nonhemorrhagic stroke and risk factors associated with stroke in patients with ACS.

Methods And Results: Data were obtained from 35,233 patients enrolled in the Global Registry of Acute Coronary Events (GRACE) with an ACS.

[Infective endocarditis complicated by abscess and perforation of mitral valve--a case report].

A case of a 47-year-old male admitted to our department due to acute myocardial infarction, treated effectively with primary angioplasty, is presented. Three weeks earlier the patient was admitted to another hospital with a suspicion of infective endocarditis. Echocardiography performed in our department after the patient recovered from acute phase of MI revealed the presence of mitral valve abscess which caused valve perforation.
