BACKGROUND: Isolated systolic hypertension and isolated diastolic hypotension are common in older adults and associated with a higher risk of incident heart failure (HF). However, little is known about the prevalence and impact of isolated diastolic hypertension in this population.

METHODS: In the Cardiovascular Health Study (CHS), of the 5776 community-dwelling older adults ≥65years who had data on baseline systolic and diastolic blood pressure (SBP and DBP), 28 had isolated diastolic hypertension (DBP ≥90mmHg and SBP

RESULTS: Patients (n=524) had a mean (±SD) age of 71 (±5) years, 58% were women and 9% African American. There were no significant between-group age or sex differences; 37% of those with isolated diastolic hypertension (versus 7% without) were African American. Incident HF occurred in 19% and 7% of participants with and without isolated diastolic hypertension, respectively (multivariable-adjusted hazard ratio {HR}, 4.65; 95% confidence interval {CI}, 1.09-19.90; p=0.038). There was a trend toward higher cardiovascular mortality (HR, 4.59; 95% CI, 0.92-23.88; p=0.063).

CONCLUSION: Among community-dwelling older adults, isolated diastolic hypertension is rare and is associated with higher risk for incident HF and cardiovascular mortality.
