Peripartum cardiac failure. A ten year follow-up study.
A cohort of patients with peripartum cardiac failure (PPCF) was followed for 10 years after the initial illness. The follow up rate was 78%. Fifty two per cent of patients improved without further episodes of heart failure. PPCF recurred in 26 per cent. Heart failure unrelated to pregnancy was seen in 13%, and 9% of the patients progressed to dilated cardiomyopathy. Transient hypertension was seen in 87% of patients on admission, and later hypertension was found in 45%. Late hypertension influenced heart size more when recurrent PPCF or progressive heart failure was present. Anaemia on admission had no effect on subsequent heart size. The electrocardiogram may continue to be abnormal for up to 10 years in normotensive patients who had no heart failure. The abnormal electrocardiogram in patients with persistent cardiomegaly may represent progressive myocardial damage. Mortality rate was highest (11%) in the first year and declined thereafter. Cardiac deaths were common in patients with recurrent PPCF or progressive heart failure.
