3. Pericardial effusion: 33 patients with pericardial effusion (18 with Stage II heart failure; and 15, Stage III) took F4 or its modification and 25 patients significantly improved (75.75 percent), 6 improved (18.15 percent) and 2 did not improve. The average heart rate dropped from 98/min to 95/min; the average blood output increased from 40 ml to 47 ml; STI (PEP/LVET) dropped from 0.5 to 0.38, ; heart functional index increased from 1.4 to 1.9 and improvements also showed in ECG and X-ray.
