Frailty and CVD are often interrelated, affecting disease and treatment outcomes. Frailty is a syndrome of physiological decline, characterized by marked vulnerability to adverse health outcomes. Patients were categorized as frail if they had a hospital frailty risk score (HFRS) of 5 or higher, and non-frail if their score was below 5.
