Overview
The chronic treatment of diastolic dysfunction involves aggressive management of the underlying disorder that is causing the diastolic dysfunction such as diabetes or hypertension. Mild diastolic dysfunction that is well tolerated requires no specific treatment. Rate control is an important part of the acute therapy of the patient with diastolic heart failure. It takes a longer period of time for a stiff left ventricle to fill, and therefore rate control is a critical part of the acute therapy of diastolic dysfunction.
Acute Treatment of Diastolic Heart Failure
Rate Control
It takes a longer period of time for a stiff left ventricle to fill, and therefore rate control is a critical part of the acute therapy diastolic dysfunction. Furthermore, in atrial fibrillation there is a failure of atrial kick to augment the filling of the left ventricle.
Diuresis
Diuresis may reduce acute volume overload.
Relief of Ischemia
Acute myocardial ischemia leads to diastolic dysfunction which increases left atrial pressure and causes pulmonary edema.
Chronic Treatment of Diastolic Heart Failure
Afterload Reduction
There is some evidence that calcium channel blocker drugs may be of benefit in reducing ventricular stiffness in some cases. Likewise, treatment with angiotensin converting enzyme inhibitors such as enalapril, ramipril, and other ACE inhibitors may be of benefit due to their effect on ventricular remodeling.

Patients With Heart Failure and Normal Left Ventricular Ejection Fraction
| Class I |
|
"1. Physicians should control systolic and diastolic hypertension in patients with heart failure and normal left ventricular ejection fraction, in accordance with published guidelines. (Level of Evidence: C)" |
|
"2. Physicians should control ventricular rate in patients with heart failure and normal left ventricular ejection fraction and atrial fibrillation. (Level of Evidence: C)" |
|
"3. Physicians should use diuretics to control pulmonary congestion and peripheral edema in patients with heart failure and normal left ventricular ejection fraction. (Level of Evidence: C)" |
| Class IIa |
|
"1. Coronary revascularization is reasonable in patients with heart failure and normal left ventricular ejection fraction and coronary artery disease in whom symptomatic or demonstrable myocardial ischemia is judged to be having an adverse effect on cardiac function. (Level of Evidence: C)" |
| Class IIb |
|
"1. Restoration and maintenance of sinus rhythm in patients with atrial fibrillation and heart failure and normal left ventricular ejection fraction might be useful to improve symptoms. (Level of Evidence: C)" |
|
"2. The use of beta-adrenergic blocking agents, ACEIs, ARBs, or calcium antagonists in patients with heart failure and normal left ventricular ejection fraction and controlled hypertension might be effective to minimize symptoms of heart failure. (Level of Evidence: C)" |
|
"3. The usefulness of digitalis to minimize symptoms of heart failure in patients with heart failure and normal left ventricular ejection fraction is not well established. (Level of Evidence: C)" |
