Urgency. In the setting of clinical practice it is often necessary to differentiate ischemic cardiomyopathy (ICMP) and dilated cardiomyopathy (DCMP), especially in case of refractory HF. Aim: To identify clinical and functional features of ICMP and DCMP in patients with refractory HF. Materials and methods. Study enrolled 61 patients with mean age of 41.05±1.05 years. Patients were assigned to two groups; group 1 consisted of 20 patients with ICMP and group 2 consisted of 41 patients with DCMP. ECG (with measurement of RV6 / RVmax ratio) and Holter ECG monitoring were performed. Dynamics of clinical and functional state was evaluated using the clinical rating scale (CRS). Results. DCMP with refractory HF was characterized by relatively young age and lower parameters of myocardial contractility. Pronounced dysfunction of both ventricles in the absence of LV wall hypertrophy was also typical for patients with DCMP.
