[Decreased Heart Rate Variability in Sickle Cell Anemia as Effect of Pulmonary Arterial Hypertension].

Decreased heart rate variability (HRV) is associated with increased mortality risk in various diseases. The objective of this investigation:to study HRV in patients with sickle cell anemia (SCA) and to assess the effect of pulmonary arterial hypertension (PAH) on HRV in these patients. Materials and methods.

[Radial Approach for Percutaneous Coronary Interventions in Patients With Ischemic Heart Disease: Advantages and Disadvantages, Complications Rate in Comparison With Femoral Approach].

During recent 10-15 years, percutaneous coronary interventions (PCI) have reached a new level of efficacy and safety. Rate of serious coronary complications has decreased. That to a greater degree exposes the problem of peripheral complications at the site of arterial approach.

[Diagnostic Possibilities of Speckle-Tracking Echocardiography].

The review is devoted to merits and demerits of a new method of assessment of condition of the heart - speckle-tracking echocardiography. Speckle-tracking echocardiography is a perspective method allowing to register disorders of both global and regional contractile motion.

[Ability to Overcome the Thrombocyte Resistance to Acetylsalicylic Acid in Patients With Coronary Artery Disease After Myocardial Revascularization With Coronary Stenting].

Resistance to acetylsalicylic acid (ASA) in patients with coronary artery disease is a poor predictor for the development of atherothrombotic complications. In 277 patients with coronary artery disease suffered uncomplicated coronary angioplasty with stent implantation, we was estimated arachidon-induced platelet aggregation during treatment with acetylsalicylic acid by bedside VerifyNow Assay test at 28-90 days after the intervention. It was found that 18.
