Association of orthostatic blood pressure response with incident heart failure: The Framingham Heart Study

Abstract

Importance Orthostatic hypotension (OH) and hypertension (OHT) are aberrant blood pressure (BP) regulation conditions associated with higher cardiovascular disease risk. The relations of OH and OHT with heart failure (HF) risk in the community are unclear and there remains a paucity of data on the relations with HF subtypes [HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF)]. Objective Relate OH and OHT with HF risk and its subtypes. Design Prospective observational cohort. Setting Community-based individuals in the Framingham Heart Study Original Cohort. Participants 1,914 participants (mean age 72 years; 1159 women) attending examination cycle 17 (1981–1984) followed until December 31, 2017 for incident HF or death. Exposures OH or OHT, defined as a decrease or increase, respectively, of ≥20/10 mmHg in systolic/diastolic BP upon standing from supine position. Outcomes and measures At baseline, 1,241 participants had a normal BP response (749 women), 274 had OH (181 women), and 399 had OHT (229 women). Using Cox proportional hazards regression models, we related OH and OHT to risk of HF, HFrEF, and HFpEF compared to the absence of OH and OHT (reference), adjusting for age, sex, body mass index, systolic and diastolic BP, hypertension treatment, smoking, diabetes, and total cholesterol/high-density lipoprotein. Results On follow-up (median 13 years) we observed 492 HF events (292 in women; 134 HFrEF, 116 HFpEF, 242 HF indeterminate EF). Compared to the referent, participants with OH [n = 84/274 (31%) HF events] had a higher HF risk (Hazards Ratio [HR] 1.47, 95% CI 1.13–1.91). Moreover, OH was associated with a higher HFrEF risk (HR 2.21, 95% CI 1.34–3.67). OHT was not associated with HF risk. Conclusions and relevance Orthostatic BP response may serve as an early marker of HF risk. Findings suggest shared pathophysiology of BP regulation and HF, including HFrEF.

Role of Orthostatic Hypotension in the Development of Dementia in People With and Without Cardiovascular Disease

“…8,9 Studies in middle-aged and elderly adults found that individuals with OH had increased risk of developing heart failure, coronary HD, atrial fibrillation, and stroke, even after controlling for other vascular risk factors. 4,28–41 However, 1 study in elderly adults did not find any associations between OH and CVD, possibly due to the limited number of incident CVD cases. 42 Our results were consistent with the previous findings that older adults with OH had a higher risk of developing CVD, both HD and stroke/TIA, compared with individuals without OH.…”
