EFFECT OF RENAL DYSFUNCTION ON THE CARDIACVASCULAR SYSTEM. THE POSSIBILI TIES OF EARLY DIAGNOSIS OF THE RENAL DYSFUNCTION

Abstract

The review is devoted to the discussion of modern concepts of the role of renal dysfunction in the development of chronic myocardial dysfunction in the context of cardio-renal syndrome (RVC) type 4. At the beginning of the review, the definition of cattle is given, general questions of pathogenesis and diagnosis of the disease are addressed. It is indicated that in patients with the initial stage of CKD, cardiovascular disorders are already registered which in the late stages of development of renal dysfunction are the leading causes of death and the true severity of the disease in patients with renal dysfunction is associated with an increased risk of cardiovascular events, rather than an achievement terminal renal failure and requiring renal replacement therapy. The progression of renal pathology leads to damage to the heart through various mechanisms and factors, both traditional and non-traditional, some of which, at the culmination of the renal continuum, are the result of the dialysis procedure itself in patients with terminal renal dysfunction. Mechanisms for the development of congestive heart failure in type 4 cattle include pressure overload (arterial hypertension) and volume (anemia, edematous syndrome), which increase in proportion to the decrease in renal function. Increase in blood pressure, changes in intracardial hemodynamics, deterioration of arterial compliance contribute to the acceleration of cardiovascular events. The role of laboratory predictors of renal dysfunction in the progression of cardiovascular disorders is discussed. The general approaches of echocardiographic visualization of the heart cavities and its importance in the diagnosis of cardiovascular diseases are discussed. Special attention is paid to the development of pulmonary arterial hypertension, changes in the left and right ventricle of the myocardium with renal dysfunction.
