INTRODUCTION Peri-procedural myocardial infarction (PMI) is a frequent and prognostically important complication of percutaneous coronary intervention (PCI). This study was designed to determine the predictors of PMI in patients pre-treated with statins. MATERIAL AND METHODS A total of 418 stable angina pectoris patients taking statins and aspirin were(More)
Cardiac metastases are rare diagnoses among cardiac disorders. This case demonstrates a unique presence of an obstruction in the left ventricular outflow tract caused by the metastasis of a renal carcinoma. Adequate diagnostic and therapeutic procedures were lifesaving in this potentially fatal diagnosis.
AIMS We decided to determine the long-term survival of patients after alcohol septal ablation (ASA) for hypertrophic obstructive cardiomyopathy (HOCM) and compare this with the general population. METHODS AND RESULTS A total of 178 highly symptomatic, consecutive patients (58 ± 12 years, 53% women) were treated by ASA between April 1998 and April 2013 and(More)
INTRODUCTION Little is known about the prognosis of moderate versus critical carotid stenosis treated by carotid artery stenting (CAS). MATERIAL AND METHODS This was a retrospective analysis of a single-centre registry including 271 consecutive patients (69 ±9 years, 87% at high risk for surgery), in whom 308 procedures were performed. The study included(More)
INTRODUCTION The aim of this prospective study was to evaluate the diagnostic accuracy of dual-source computed tomography coronary angiography (CTCA) compared to intravascular ultrasound (IVUS) for the detection of restenosis in patients who underwent coronary stenting for bifurcation left main (LM) stenosis. MATERIAL AND METHODS Twenty-four patients(More)
Aim: The authors investigated the utility of strain, strain rate, and tissue Doppler imaging (TDI) for the evaluation of the right ventricle (RV) impairment in patients with a hypertrophic obstructive cardiomyopathy (HOCM) after a successful alcohol septal ablation (ASA) without RV hypertrophy in comparison with control group. Methods and Results: A group(More)
INTRODUCTION A left ventricular outflow tract (LVOT) obstruction assessment with a provoking test should be a routine part of the evaluation of patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to compare the utility of the Valsalva maneuver (VM) and sublingual spray application of isosorbide dinitrate (ISDN) for detection of an(More)
AIMS Hypertrophic cardiomyopathy (HCM) is predominantly associated with left ventricular outflow tract (LVOT) obstruction. The assessment of the obstruction with a provoking test should be a routine part of HCM evaluation. The aim of the study was to determine the utility of a sublingual spray application of isosorbide dinitrate (ISDN) for detection of an(More)
BACKGROUND Statins have been proved to be effective in reduction of mortality and morbidity when started in the early secondary prevention in stabilized patients after acute coronary syndrome (ACS). The safety and efficacy of statin administration directly in the first-line therapy in unstable ACS patients is not clear. The aim of our study was, therefore,(More)
Questionnaires were sent to interdisciplinary UAF programs across the country to assess the types of handicapped school children who were receiving services at their facilities. A return rate of 65 percent was obtained and the total sample of children was 2088. Results indicated that a wide variety of ages and handicapping conditions were reported. Referral(More)
