Emerging facets of diastolic heart failure.

ABSTRACT

One hundred patients with congestive cardiac failure (52 males and 48 females) with age ranging from 16 to 56 yrs (mean age 42 +/- 6) were studied to determine the relative prevalence of systolic and diastolic failures, their clinical profiles and common aetiologies. Age matched 25 control subjects were also studied to established a normal range of echocardiographic values for LV diastolic function. Thirty eight patients (38%) were found to have pure diastolic heart failure and another 5 (5%) and 57 (57%) were detected to have mixed and systolic failures respectively. An attempt to correlate the clinical assessment of diastolic failure with echo doppler study showed the sensitivity and specificity of the clinical criteria for diagnosis of diastolic heart failure to be 100% and 91.94% respectively. Of the 38 cases of diastolic failure detected 39.5% had hypertension, 31.6% ischaemic heart disease and 13.16% hypertrophic cardiomyopathy.
