Abstract/OtherAbstract:
In patients with hypertension, pressure overload leads to left ventricular hypertrophy (LVH), myocardial fibrosis, and impaired diastolic filling without systolic dysfunction. Presently, diastolic heart failure accounts for about 50% of the heart failure population. Fatigue, dyspnea, reduced exercise tolerance, and peripheral edema are common presenting complaints. As a group, patients with diastolic heart failure are older and predominantly female. Diuretics are effective for treating congestive symptoms. beta Blockers and heart rate-lowering calcium blockers show benefit in smaller studies but have not been evaluated in definitive clinical trials. Renin-angiotensin-aldosterone system blockers reduce blood pressure, LVH, and myocardial fibrosis; however, long-term studies with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers demonstrate little effect on symptoms or survival, and inconsistent effects on heart failure hospitalization. At present, evidence-based treatment includes antihypertensive therapy to reduce progression from hypertension to heart failure. In patients with established heart failure, diuretics and other empiric treatments are used to control symptoms.
