The short physical performance battery and incident heart failure among older women: the OPACH study.

OBJECTIVE: Reduced functional capacity is a hallmark of early pre-clinical stages of heart failure (HF). The Short Physical Performance Battery (SPPB) is a valid measure of lower extremity physical function, has relatively low implementation burden, and is associated with cardiovascular disease and mortality. However, the SPPB-HF association is understudied in older women among whom HF burden is high. METHODS: Women (n = 5325; mean age 79 ± 7 years; 34% Black, 18% Hispanic, and 49% White) without prior HF completed the SPPB consisting of standing balance, strength, and walking tests that were summarized as a composite score from 0 (lowest) to 12 (highest), categorized as very low (0-3), low (4-6), medium (7-9), or high (10-12). Participants were followed for up to 8 years for incident HF (306 cases identified). Cox proportional hazards regression estimated hazard ratios (HR) adjusting for age, race/ethnicity, education, smoking, alcohol, diabetes, hypertension, COPD, osteoarthritis, depression, BMI, systolic blood pressure, lipids, glucose, and accelerometer-measured moderate-vigorous physical activity (MVPA) and sedentary time. RESULTS: Incident HF cases (crude rate per 1000 person-years) in the four SPPB categories (very low to high) were 34 (26.0), 79 (14.5), 128 (9.3), and 65 (5.6). Corresponding multivariable-adjusted HRs (95% CIs) were 2.22 (1.34-3.66), 1.63 (1.11-2.38), 1.39 (1.00-1.94), and 1.00 (referent; P-trend<0.001). Higher HF risk was associated with lower SPPB in women with major modifiable HF risk factors including obesity (HR per 3-unit SPPB decrement: present HR = 1.41, absent HR = 1.41), hypertension (present HR = 1.45, absent HR = 1.30), diabetes (present HR = 1.32, absent HR = 1.44), and lower accelerometer-measured MVPA (<45 min/day HR = 1.29, ≥45 min/day HR = 1.60); all P-interaction>0.10. CONCLUSION: Lower SPPB scores were associated with greater risk of incident HF in older women even after accounting for differences in HF risk factors and objectively measured PA. Implementing the SPPB in clinical settings could potentially enhance individual-level HF risk assessment, which should be further explored.

Short Physical Performance Battery and Incident Cardiovascular Events Among Older Women.

Background The Short Physical Performance Battery (SPPB) is an inexpensive, reliable, and easy-to-implement measure of lower-extremity physical function. Strong evidence links SPPB scores with all-cause mortality, but little is known about its relationship with incident cardiovascular disease (CVD). Methods and Results Women (n=5043, mean age=79±7) with no history of myocardial infarction or stroke completed 3 timed assessments-standing balance, strength (5 chair stands), and usual gait speed (4 m walk)-yielding an SPPB score from 0 (worst) to 12 (best). Women were followed for CVD events (myocardial infarction, stroke, or CVD death) up to 6 years. Hazard ratios were estimated for women with Very Low (0-3), Low (4-6), Moderate (7-9), and High (10-12) SPPB scores using Cox proportional hazard models adjusted for demographic, behavioral, and health-related variables including objective measurements of physical activity, blood pressure, lipids, and glucose levels. Restricted cubic splines tested linearity of associations. With 361 CVD cases, crude incidence rates/1000 person-years were 41.0, 24.3, 16.1, and 8.6 for Very Low, Low, Moderate, and High SPPB categories, respectively. Corresponding fully adjusted hazard ratios (95% CIs) were 2.28 (1.50-3.48), 1.70 (1.23-2.36) 1.49 (1.12-1.98), and 1.00 (referent); P-trend <0.001. The dose-response relationship was linear (linear P<0.001; nonlinear P>0.38). Conclusions Results suggest SPPB may provide a measure of cardiovascular health in older adults beyond that captured by traditional risk factors. Because of its high test-retest reliability and low administrative burden, the SPPB should be a routine part of office-based CVD risk assessment.

Envejecimiento cardiovascular saludable / Healthy Cardiovascular Aging

Introducción: el envejecimiento es una situación biológica normal, se produce dentro de un proceso dinámico, progresivo, irreversible, complejo y variado, difiere en la forma en cómo afecta a las distintas personas e incluso a los diferentes órganos. Las enfermedades cardiacas constituyen la principal causa de morbimortalidad en los ancianos y es la segunda causa de mortalidad para todas las edades. Objetivo: caracterizar el envejecimiento cardiovascular saludable. Métodos: revisión bibliográfica documental de artículos publicados en Internet y en literatura impresa. Conclusiones: el sistema cardiovascular del anciano se asocia con alteraciones morfofuncionales que afectan los vasos sanguíneos, el miocardio y las válvulas cardíacas(AU)

Introduction: Aging is a normal biological condition. It occurs within a dynamic, progressive, irreversible, complex and varied process, differing in the way it affects different people and even different organs. Heart disease is the leading cause of morbidity and mortality in the elderly and it is the second cause of death for all ages. Objective: Characterize cardiovascular healthy aging. Methods: A documentary literature review was conducted of articles published in the Internet and in printed literature. Conclusions: The cardiovascular system of the elderly is associated with morphological and functional alterations affecting blood vessels, myocardium, and heart valves(AU)
