Frailty and cardiovascular disease: a bidirectional relationship with clinical implications

Area of Science:

• Gerontology
• Cardiology
• Public Health

Background:

• Frailty and cardiovascular disease (CVD) are increasingly prevalent in aging populations.
• Frailty affects 10%-15% of community-dwelling older adults, increasing vulnerability to stressors and adverse CVD outcomes.
• Shared pathophysiological mechanisms link frailty and CVD, including chronic inflammation and endothelial dysfunction.

Purpose of the Study:

• To synthesize evidence on the interplay between frailty and CVD.
• To evaluate current frailty assessment tools and interventions in cardiovascular populations.
• To highlight the need for integrating frailty assessment into routine cardiovascular care.

Main Methods:

• Systematic review of studies published between 2000-2025 from Google Scholar and PubMed.
• Keywords used: "frailty", "CVD", "frailty assessment", "multicomponent interventions".
• Analysis of frailty prevalence, predictive value, assessment tools, and intervention efficacy.

Main Results:

• Frailty prevalence varies by CVD subtype (30% in CAD to 80% in HF) and independently predicts a 2.5-3.5 fold higher mortality risk.
• No gold standard frailty assessment tool exists for cardiovascular populations; traditional risk scores often overlook frailty.
• Multimodal interventions, particularly combined exercise and nutrition (e.g., VIVIFRAIL, SPRINT-T), show efficacy in improving physical function and frailty severity.

Conclusions:

• Routine frailty assessment is necessary in cardiovascular care for improved risk stratification and personalized treatment.
• Standardizing assessment tools and developing targeted interventions for shared pathways are critical future research directions.
• Addressing frailty as a modifiable risk factor can significantly enhance outcomes for older adults with CVD.
