abstract
BACKGROUND: Racial and gender differences in mortality rates have been reported for patients with systolic heart failure. Relatively little is known regarding diastolic heart failure prognosis. METHODS: Our sample consisted of 1058 patients 65 years of age or older who were admitted to 30 hospitals in Northeastern Ohio with a principal diagnosis of heart failure and a left ventricular ejection fraction of >/=50% by echocardiogram. RESULTS: Of the 1058 patients with diastolic heart failure (13% African American and 87% white), African Americans and whites were comparable with respect to history of angina, stroke, being on dialysis, and alcohol use; the proportion of male patients was also comparable. The African American to white adjusted odds ratio for 18-month mortality (all cause) was 1.03 (0.66-1.59). For men versus women (30% vs 70%), the above-mentioned comorbidities were comparable, except women were more likely to have a do not resuscitate status (16% vs 7.3%; p =.000) and to be older (79.5 +/- 8 vs 77 +/- 7; p =.000). Men were more likely to have a history of tobacco use (30% vs 14%; p =.000) and alcohol use (36% vs 15%; p =.000), and a higher serum creatinine level (1.7 +/- 1.2 vs 1.4 +/- 1.1; p =.001). The men to women adjusted odds ratio for 18-month mortality (all cause) was 1.06 (0.76-1.46). CONCLUSION: In this cohort of elderly patients admitted with diastolic heart failure, there were no ethnic or gender differences in 18-month mortality rates.
