Aim. To assess role of 24 hour heart rate variability (HRV) for prognosis of patients with chronic heart failure (CHF) and systolic dysfunction in the era of wide use of b-adrenoblockers. Material. Patients (n=135) with symptomatic CHF and ischemic (68%) or nonischemic cardiomyopathy (32%) with systolic left ventricular (LV) dysfunction and sinus rhythm(More)
The review is devoted to different aspects of pulmonary arterial hypertension (PAH); new classification of PAH is published in 2010. There are idiopathic PAH and PAH associated with other diseases. Current guidelines recommend to treat PAH only after the verification of diagnosis with right heart catheterization and acute tests with vasodilators.(More)
To evaluate the severity of chronic circulatory insufficiency (CCI), 12 healthy subjects and 69 patients with cardiovascular diseases underwent exercise testing. Parameters such as anaerobic threshold (AT) and peak oxygen consumption (peak VO2) were measured by respiratory gas analysis to assess the circulatory insufficiency. AT decreased with an increase(More)
Dilated cardiomyopathy (DCM) is characterized by enlargement and dilation of all heart compartments associated with serious decrease of its contractile function. DCM hallmark is the combination of dystrophic and hypertrophic alterations of cardiomyocytes. Since the power output of cardiac cells is directly related to remodeling of their contractile(More)
The review contains current insights into the role of free radical processes in formation of oxidative stress in atherosclerosis and its relevance to therapy and prevention. Data of epidemiological studies evidence for existence of correlations between blood plasma content of antioxidant vitamins and presence of signs of atherosclerosis. However mostly(More)
Data are presented on the effect of nitroglycerin upon the intracardiac haemodynamics studied by means of echocardiography in normal individuals and in patients with ischaemic heart disease. Three types of changes in the intracardiac haemodynamics under the effect of the drug were revealed. The possible mechanism of action of nitroglycerin is discussed in(More)
We studied the influence of rosuvastatin therapy and myocardial revascularization on angiogenic growth factors in coronary artery disease (CAD) patients. Two main groups were examined: the first one consisted of patients passed through successful percutaneous coronary intervention (PCI), the second one consisted of patients on 3 months rosuvastatin therapy.(More)
UNLABELLED The use of beta-adrenoblockers in conjunction with angiotensin converting enzyme inhibitors improves quality of life and prognosis of patients with chronic heart failure. However basic mechanisms of these positive effects in severe heart failure remain to be elucidated. METHODS Patients (n=54) with NYHA class III-IV heart failure and left(More)
PURPOSE To study mechanisms of immune derangements in coronary heart disease (CHD). MATERIAL AND METHODS We measured basic markers of immune activation in 43 patients with CHD and NYHA I-IV class heart failure (HF). There were 41 men and 2 women aged 33 - 64 years (mean 48 +/- 8 years). Concentrations of hsCRP, IgA, IgM, IgG were measured using(More)
