Frailty status and cardiovascular disease risk profile in middle-aged and older females.
2020
Abstract Objective Frailty and pre-frailty are known to increase the risk of developing cardiovascular disease (CVD). However, the risk profiles of females are not well characterized. The aim of this study is to characterize the CVD risk profiles of robust, pre-frail and frail females. Methods Cross-sectional analysis of 985 females ≥55 years with no self-reported history of CVD were recruited. Frailty was assessed using the Fried Criteria with the cut-points standardized to the cohort. Framingham risk scores (FRS), the 4-test Rasmussen Disease Score (RDS), and the CANHEART health index were used to characterize composite CVD risk. Individual measures of CVD risk included blood lipids, artery elasticity assessments, exercise blood pressure response, 6-min walk test (6MWT), sedentary time and PHQ-9 score. Results The cohort comprised of 458 (46.4%) robust, 464 (47.1%) pre-frail and 63 (6.4%) frail females with a mean age of 66 ± 6 (SD) years. Pre-frail females were at increased odds of taking diabetes medications (OR 3.04; 95% CI 1.27–7.27), hypertension medications (OR 2.02; 95% CI 1.44–2.82), having an exaggerated blood pressure response to exercise (OR 1.878; 95% CI 1.39–2.50), mild depression symptoms (OR 2.38; 95% CI 1.68–338), and lower fitness as assessed by 6MWT (OR 5.74; 95% CI 3.18–10.37), even after controlling for age and relevant medications. Pre-frail females were also at increased odds for having CVD risk scores indicating higher risk with the FRS (OR 1.52; 95% CI 1.12–2.05), the RDS (OR 1.60; 95% CI 1.21–2.10) and the CANHEART risk score (OR 3.07; 95% CI 2.04–4.62). These odds were higher when frail females were compared to their robust peers. Conclusion Frailty and pre-frailty were associated with higher odds of presenting with CVD risk factors as compared to robust females, even after controlling for age.
