Objective: As blood pressure rises with age, the majority of the elderly have hypertension. Population of older hypertensive patients is highly heterogeneous group, and their physiological ability and vulnerability which is called frailty vary widely even in same chronological age. However, there have been few studies regarding the effect of frailty on hypertension. Design and Method: We analyzed the data of the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-1), 2012 which contains 4363 older adults (age ≥ 65) data. We constructed a frailty index (FI) with 42-items and classified participants as robust (FI ≤ 0.2), pre-frail (0.20.35). Chi-square test and one-way analysis of variance (One-way ANOVA) were used to evaluate the association of the frailty status with prevalence, treatment and control of hypertension. Results: The mean age was 72.8 ± 5.52 years and 1,954 (42.9%) participants were men. In total cohort, 2795 participants (64.1%) had hypertension and 873 (20.0%) had pre-hypertension. In terms of frailty status, 2383 (54.6%), 1538 (35.3%) and 442 (10.1%) individuals were classified as robust, pre-frail and frail, respectively, and the frailty status was associated with hypertension with statistical significance (P Conclusions: The prevalence of hypertension is correlated with frailty status in the elderly and frail patients are more likely to be treated than pre-frail or robust patients. However, control rate does not differ from each other, and lower diastolic BP is more frequent in treated frail patients which can cause falls and adverse cardiovascular outcomes.

Objective: Atrial fibrillation is the common arrhythmia in the elderly, and the average age of atrial fibrillation patients is rising. Elderly patients with atrial fibrillation have high incidence of thromboembolic complication and increasing age is associated with stroke severity. Assessing CHADS-VASc score is pivotal to evaluate substantial morbidity and mortality, especially regarding the increased risk of stroke. In addition, considering bleeding risk with HAS-BLED score is important to balance the benefit against the risk of bleeding. However in addition to CHADS-VASc and HAS-BLED score, the roll of frailty assessment in older atrial fibrillation patients is not known. Design and Method: We evaluate 365 older (≥ 65 years old) atrial fibrillation patients who underwent comprehensive geriatric assessment (CGA) from 2007 to 2014 in a single tertiary hospital retrospectively. Taking anti-coagulant or anti-platelet agents on the point of CGA were reviewed. CHADS-VASc and HAS-BLED scores were calculated based on electronic medical records, and frailty index was computed from CGA. The primary outcome was the 3-year all-cause mortality. Results: Patients with high CHADS-VASc score were more likely to be treated with anticoagulant rather than antiplatelet agent (P Conclusions: Frailty assessment along with CHADS-VASc and HAS-BLED score can provide fine resolution for predicting mortality in older atrial fibrillation patients.
