Rationale of Afterload Reduction Therapy Facilitation of ventricular emptying leading to increasing lowered stroke volume is the funda mental objective of therapy for heart failure. Conventional treatment of congestive heart fail ure has focused primarily on increasing ven tricular stroke volume and cardiac output

1) Vasodilators - Drugs that decrease either preload or afterload. · 2) Diuretics - promote the elimination of edematous fluid, improving tissue perfusion and

The afterload is the amount of pressure that the heart needs to exert to eject the blood out if it during the Mechanism. The The afterload of any contracting muscle is defined as the total force that opposes sarcomere shortening minus the stretching force that existed before contraction. Applying this definition to the heart, afterload can be most easily described as the "load" against which the heart ejects blood. Afterload reduction therapy should be goal directed with the intent to improve stroke volume and tissue oxygen delivery rather than to decrease blood pressure per se. This review will summarize the components comprising circulatory system afterload and will use ventriculoarterial coupling concepts to demonstrate the variable but predictable effects of vasodilator therapy on hemodynamics and Packer M, Meller J, Gorlin R, Herman MV: Hemodynamic and clinical tachyphylaxis to prazosin-mediated afterload reduction in chronic congestive heart failure.

Alex. Fac. Med. 1994; 30 (3): 597-603 Abstract English The chronic hemodynamic effects of captopril were assessed in 22 asymptomatic patients with a moderate to severe isolated aortic regurgitation [AR] before and 3 months after administration of captopril [50-100 mg/day]. 2010-02-23 2020-04-30 Decreasing afterload and increasing inotropic both reduce end-systolic volume, which cause the end-diastolic volume to decrease secondarily. Reduced venous pressure decreases capillary pressure and fluid filtration in the lungs (left-sided failure) and systemic tissues (right-sided failure), thereby diminishing the edema.

However, the effect may be beneficial in the context of decompensated heart failure, where the decreased preload and afterload result in a return to a more productive part of the Starling curve. Remarkable reduction in early mortality was achieved over the 12 years reported. Adamant afterload reduction was the main key in improving systemic blood flow. In this respect, alpha blockade was superior to the use of sodium nitroprusside.
