Interdependence of Obstructive Changes in the Coronary Arteries and Clinical Manifestations of Heart Failure in Patients Who Have Suffered Myocardial Infarction
In patients who have suffered a myocardial infarction (MI), heart failure (HF) is caused by a decrease in the pumping function of the heart when a significant portion of the myocardium is activated from contraction. Impairment of the pumping function of the left ventricle of the heart without clinical signs of HF or with minimal, as well as with its pronounced manifestations, on Our opinion should be considered in the aspect of hemodynamic supply to the left ventricles (LV). The New York Heart Association has developed a classification of heart failure into class IV (Stages). At the same time, identifying circulatory decompensation taking into account clinical and angiographic signs is important for assessing the condition of patients and selecting drug therapy. And also when developing indications for surgical correction of this complication.
