Angiotensin-converting enzyme inhibitors and beta-blockers provide life-saving benefits in most of the subpopulations assessed. Women with asymptomatic LV systolic dysfunction may not achieve a mortality benefit when treated with ACE inhibitors.

During chronic therapy tailored to early hemodynamic response in advanced heart failure, acute vasodilator response persists, and near-normal filling pressures can be maintained in patients who survive without transplantation. Stroke volumes at low filling pressures increase further over time. Chronic hemodynamic improvement was accompanied by symptomatic improvement, but the contributions of the monitored hemodynamic approach, increased vasodilator doses, and comprehensive outpatient management have not yet been established.

The prognosis of patients with advanced heart failure and atrial fibrillation is improving. These findings support the practice of avoiding class I antiarrhythmic drugs in this group and may reflect recent beneficial changes in heart failure therapy.
