A method for treating patients suffering from left ventricular dysfunction is disclosed. The method involves applying, during diastole, for a time period of about one hour, at least five days each week for at least about six weeks, an incrementally increasing external therapeutic pressure sequentially to the patients' lower extremities from first the calves, then the thighs and last the buttocks. The initial hourly treatments are carried out at a peak diastolic/systolic pressure ratio (D/S Ratio) in the range of about 0.4:1 up to about 0.9:1, depending on the patient's left ventricular ejection fraction. The D/S Ratio is increased slightly during the next set of hourly treatments, the D/S Ratio is again increased slightly during the next following set of hourly treatments, the D/S Ratio is again increased slightly during the next set of hourly treatments, and finally the D/S Ratio is increased slightly and maintained during the remaining set of hourly treatments. The patient's cardiopulmonary functions preferably are monitored to determine if additional external therapeutic pressure treatments are needed.
