What is the simple management strategy for reversing diastolic dysfunction?
Posted Dec 14 2009 5:55am
Diastolic dysfunction is a common clinical cardiac problem which has no specific therapy.It can occur either in isolation or in combination with systolic dysfunction.The later may be more common.
Isolated diastolic dysfunction
Hypertensive heart disease.
Aortic valvular stenosis
Restrictive cardiomyopathy
Early stages of CAD
Pericardial disorders
Idiopathic stiff ventricles
In association with systolic dysfunction
Dilated cardiomyopathy (20%)
In any form of cardiac failure some degree of diastolic dysfunction is noted .
General principles of management
Even though there is no specific drugs to tackle diastolic dysfunction the following measures may have significant impact.
Correct the underlying problem.(HT/CAD etc)
Reduce the basal heart rate .At lower heart rates as diastole is prolonged , the stiff muscles has extra time to relax and stretch itself longer.
Regular isotonic exercise preconditions the muscle for smooth contraction relaxation .
Optimise diuretics (Excessive diuretics has an adverse effect on the diastolic pressure profile across the AV valves)
Avoiding positive inotropic agents like digoxin .This will not be possible in combined dysfunction.
ACE inhibitors, ARBs, Aldosterone have some benefits as they could prevent tissue proliferation in the cardiac interstitium
Milrinone (The non digoxin positive inotrpic)show some promise

What are the treatments in the horizon ?
Antifibrotic drugs ,Antiproliferative drugs
Collagen breakers ,
