Aging is related to the redistribution of central body fat and skeletal muscle decline, but the relationship between tissue compartments and heart failure (HF) is still not completely clear
.
Recently, the heart blood vessels published a research article on the disease areas authoritative magazine JAHA, the researchers aimed to assess the body composition of elderly heart failure impact of the event
.
Participants from two elderly cohorts who completed dual-energy X-ray absorptiometry (DEXA) and computed tomography were included in the study
.
The evaluators evaluated the main components (PC) of DEXA and the correlation between total lean body mass, limb lean mass, total fat and trunk fat mass and HF; as well as abdominal viscera and subcutaneous fat, thigh muscles, and thigh muscles measured by computed tomography.
During a median follow-up of 11.
8 years, 927 participants had an HF event
.
There is no relationship between DEXA principal components and HF events
It can be seen that total lean body mass is positively correlated with the occurrence of HF, while total fat mass and thigh muscle density are negatively correlated with the incidence of HF
.
These findings emphasize the limitations of DEXA in assessing the risk of HF in the elderly, and support that the mass of skeletal muscle measured by computed tomography is better than its weight as a determinant of the occurrence of HF
Total lean body mass is positively correlated with the occurrence of HF, while total fat mass and thigh muscle density are negatively correlated with the occurrence of HF
