What are the causes of diastolic heart failure? can it be functional, or is it just structural? my neurologist did a tilt table test, said my heart contraction phase is longer than my relaxation phase. i never had heart pain, breathlessness, before a

Diastolic heart fail: Diastolic dysfunction is secondary to defect in the relaxation of the of the heart muscle, High blood pressure can cause this problem from thickened heart muscles.,

DHF : The causes of diastolic heart failure include anything that causes stiffness of one or both of the ventricles. Hypertension with increased heart muscle, narrowing of the aortic valve, diabetes, construction of the sac around the heart and diseases associated with infiltration of abnormal proteins or cells are causes. The significance of the tilt test is not clear an echocardiogram should be done.

Various: Diastolic dysfunction and heart failure result when the pressure required to passively fill the heart prior to cardiac contraction is too high. This can result from chronic hypertension, aging, and probably some hereditary factors. Cardiac ischemia may also play a role. We generally treat by avoiding high BP, treating obesity and sleep apnea and avoiding tachycardia.
