Objectives:
To examine the separate and joint association between physical activity and frailty and long-term all-cause and cardiovascular disease (CVD) mortality in older adults.
Design:
Population-based prospective cohort study.
Setting:
Cohort representative of the noninstitutionalized Spanish population.
Participants:
Individuals aged 60 and older (N=3,896) in 2000-01.
Measurements:
Participants reported their physical activity using a validated instrument, and frailty was ascertained using the Fatigue, low Resistance, limitation in Ambulation, Illness and weight Loss (FRAIL) scale. Those with 0 frailty criteria were considered to be robust, with 1 or 2 criteria to be prefrail, and with 3 of more criteria to be frail. Participants were followed until 2014 to identify all-cause and CVD deaths. Associations were summarized using hazard ratios (HRs) and Cox regression after adjustment for main covariates.
Results:
During a median 14 years of follow-up, 1,801 total deaths occurred, 672 from CVD. Compared with being robust, the multivariate hazard ratio (95% confidence interval) for all-cause mortality was 1.29 (1.14-1.45) in prefrail individuals, and 2.16 (1.82-2.58) in frail individuals (p-trend <.001). Compared with being physically inactive, being physically active was associated with a statistically significant 18% (1-32%), 28% (16-39%) and 39% (17-55%) lower all-cause mortality among robust, prefrail, and frail individuals, respectively (all p <.001). Compared with participants who were robust and physically active, those who were frail and inactive showed the highest all-cause mortality 2.45 (95%CI: 1.95-3.06); however, the hazard ratio (95% confidence interval) for all-cause mortality in frail individuals who were physically active was comparable to that in pre-frail and inactive participants: 1.70 (1.32-2.19) and 1.56 (1.34-1.82), respectively. Mortality of prefrail active participants was similar to that of robust inactive participants. Results were similar for CVD mortality.
Conclusion:
Physical activity might partly compensate for the greater mortality risk associated with frailty in old age. J Am Geriatr Soc 66:2097-2103, 2018.

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
