The investigators will conduct a single-center randomized clinical trial at the Jewish General Hospital; an academic tertiary care center in Montreal, Quebec. Researchers will pre-screen stable patients 65 years of age admitted to the cardiovascular unit. The investigators will target those that consent and have evidence of frailty or pre-frailty according to the EFT (score 1/5). The EFT consists of a chair rise test to screen for physical frailty, a mini-cog test to screen for cognitive impairment, a hemoglobin level and a serum albumin level. Patients will be randomly allocated to the usual-care control group, or the intervention group that will receive targeted treatments depending on the EFT deficits identified. All patients will be outfitted with a hip-worn accelerometer to monitor position, step count, and sleep data during the study period. Patients will undergo a structured questionnaire and physical performance assessment at baseline (upon index admission) and at discharge, and will be contacted by telephone 30 days post-discharge to assess their recovery. The primary endpoint will be represented by the EQ-5D scale (mobility, self-care, mood, pain, and physical activity) measured by blinded observers.
