Abstract

Epidemiologic findings indicate that unfavorable cardiovascular (CV) risk profiles, such as elevated systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C), and overweight, decelerate with aging. Few studies, however, have evaluated the association between the CV risk profile and frailty. We performed a cross-sectional analysis using the baseline data of a prospective cohort study. A total of 599 subjects (age, 78 [range: 70-83] years; men, 50%) were analyzed in an outpatient setting. Frailty was diagnosed in 37% of the patients according to the Kihon Checklist score. An unfavorable CV risk profile was associated with a lower risk of frailty. The adjusted odds ratios (ORs; 95% confidence interval [CI]) of each CV risk factor for frailty were as follows: SBP (each 10 mmHg increase) 0.83 (0.72-0.95), LDL-C (each 10 mg/dl increase) 0.96 (0.86-1.05), and body mass index (each 1 kg/m2 increase) 1.03 (0.97-1.10). Moreover, the total number of CV risk factors within the optimal range was significantly associated with the risk of frailty with the following ORs (95% CI): 1, 2.30 (0.75-8.69); 2, 3.22 (1.07-11.97); and 3, 4.79 (1.56-18.05) compared with patients having no risk factors within optimal levels (p for trend 0.008). Abnormal homeostasis might lead to lower levels of CV risk factors, which together result in "reverse metabolic syndrome." Our findings indicate that a favorable CV risk profile is associated with frailty.
