SKIN MICROCIRCULATION IN PATIENTS WITH HEART FAILURE WITH DIFFERENT LEFT VENTRICULAR SYSTOLIC DYSFUNCTION
Aim. To study the relationship of mechanisms of microcirculation regulation and intracardiac hemodynamics in patients with heart failure (HF). Material and methods. In eighty patients with NYHA class II-IV HF, microcirculation was assessed by laser Doppler flowmetry and intracardiac hemodynamics - by echocardiography. Results. The patients were divided into 3 groups depending on HF type: with preserved ejection fraction (CHpEF) (>50%) - 27 patients, mid-range EF (CHmrEF) (40-50%) - 25 patients, reduced EF (CHrEF) (Conclusion. In patients, regardless of left ventricular EF, satisfactory perfusion was obtained, which is achieved due to inhibition of active mechanisms and compensatory activation of passive mechanisms of microcirculation regulation. The relationship between the development of myocardial remodeling and microcirculatory dysfunction is noted.
