Abstract
BACKGROUND: The associations of age at orthostatic hypotension onset with incident myocardial infarction (MI), stroke, and dementia remain unknown. This study aimed to examine whether younger onset age of orthostatic hypotension was associated with higher risks of incident MI, stroke, and dementia.</p>
METHODS: Data were obtained from the UK Biobank. Information on the diagnosis of orthostatic hypotension, MI, stroke, and dementia was collected at baseline (2006-2010) and follow-ups (median=13 years). The propensity score matching method and the Cox proportional hazard models were employed.</p>
RESULTS: A total of 448 374 adults (mean age: 56.8±8.1 years), of whom 3795 had orthostatic hypotension, were included. orthostatic hypotension patients exhibited higher risks of developing MI, stroke, and dementia than non-orthostatic hypotension participants. Importantly, among orthostatic hypotension patients, younger onset age (per 10-year decrement) was significantly associated with high risks of MI (HR=3.15, 95% CI: 2.54 to 3.90, P<0.001), stroke (HR=1.72, 95% CI: 1.33 to 2.23, P<0.001), and dementia (HR=1.26, 95% CI: 1.02 to 1.57, P=0.034). After propensity score matching, orthostatic hypotension patients had significantly higher risks of MI, stroke, and dementia than matched controls among all onset age groups, and the HRs gradually increased with descending onset age.</p>
CONCLUSIONS: Younger onset age of orthostatic hypotension was associated with higher risks of incident MI, stroke, and dementia, underscoring the necessity to pay additional attention to the cardiovascular health and neurocognitive status of individuals diagnosed with orthostatic hypotension at younger ages to attenuate subsequent risks of incident cardiovascular diseases and dementia.</p>
