Association between the frailty index and all-cause and cardiovascular mortality in a population with cardiovascular-kidney-metabolic syndrome: Insights from the NHANES 2011-2018

Key Points

• All-cause mortality is significantly linked to the frailty index in individuals with cardiovascular-kidney-metabolic syndrome.
• The study shows that higher frailty scores correlate with increased cardiovascular mortality risk.
• Analysis from NHANES data spanning 2011-2018 reveals critical insights into mortality patterns.
• Understanding these associations may help identify at-risk populations for better health strategies.
