Results: The incidence of DVT of the lower limbs of patients with chronic heart failure grade III, IV by NYHAFC is 42.6 percent (58/136 patients). The average age is 74 (74.1 percent 11.4). Women is 67.2 percent. 5.2 percent patients have swelling in the lower extremities. The incidence of DVT is similar in the right and the left legs (65.5 percent and 67.2 percent, respectively). The incidence of DVT in both 2 legs is 32.8 percent (19/58 patients), in only 1 leg is 67.2 percent (39/58 patients).
