摘要
Background: Frailty, a geriatric syndrome reflecting a state of reduced physiological reserve and increased vulnerability, is an independent risk factor for cardiovascular morbidity and mortality. However, the relationship between frailty and hypertensive end-organ damage is not fully established. Method and results: We performed a cross-sectional study to investigate the association between frailty and end-organ damage in 1125 apparently healthy middle-aged to elderly subjects. We performed a simple frailty ( SF) score that was easily obtainable in the office, in combination with low hand grip power and short one-leg standing (OLS) time. The association between SF score and hypertensive end-organ damage and other frailty-related parameters was evaluated. Odds ratio of SF score 1 to score 0 for the presence of hypertension was 1.9 [1.4-2.5, p < .0001] and that of SF score 2 was 3.3 [2.1-5.3, p < .0001]. SF score was also significantly associated with brachial-ankle pulse wave velocity (baPWV) and central pulse pressure (PP2). SF score was significantly associated with higher frailty index calculated from 21 parameters, lower cognitive test score, % vital capacity, skeletal muscle mass, and thigh muscle cross-sectional area. SF score was positively associated with stage of brain white matter hyperintenisty, plasma levels of B-type natriuretic peptide, and urinary protein excretion, even after correction for confounding parameters including baPWV and PP2. Conclusions: These findings indicate that frailty is significantly associated with end-organ damage in elderly subjects. SF score may be a useful clinical tool to identify frail subjects and advanced end-organ damage in elderly subjects.
