摘要：
The invention provides a treatment for congestive heart failure (CHF) in a patient. At least one pressure applicator is arranged externally around a body segment of the patient. Negative pressure, relative to atmospheric pressure, is applied to the body segment of the patient during cardiac systole using the pressure applicator, thereby reducing ventricular afterload in the patient. The negative pressure to the body segment of the patient is removed during cardiac diastole.
