Cardiovascular diseases (CVDs) and chronic kidney disease (CKD) are common causes of morbidity and mortality. However, the impact of changes in lifestyle and rehabilitation programs on the progression of cardiovascular, renal, and metabolic (CRM) conditions, remains unclear. In a retrospective manner, we analyzed charts of 200 patients admitted for cardiorespiratory rehabilitation at our facility in 2023. A 6 min walk test, echocardiographic features, and laboratory values were investigated to evaluate the impact of cardiorespiratory rehabilitation in patients post cardiac surgery. This study examined the impact of combined lifestyle and exercise scores (diet, alcohol consumption, smoking, aerobic physical activity, sedentary behavior, sleep duration, and social connection) on cardio-renal-metabolic profiles and on a quality-of-life score measured by the Borg Scale. During the rehabilitation program, left ventricular ejection fraction (LVEF) significantly increased (51.2 vs. 54.3%, SEM 0.51 p = 0.001). The six-minute walk test (6 MWT) significantly improved in terms of meters (133 vs. 373 m, SEM 6.41, p < 0.001) and Borg scale (6.6 vs. 2.5, SEM 0.06, p < 0.001). Glycemia levels reduced significantly (114.5± vs. 107.4± mg/dL, SEM 2.45, p = 0.001). While total cholesterol levels (119.4 vs. 129.6 mg/dL, SEM 2.4, p < 0.001) as well as HDL levels (29.9 vs. 40 mg/dL, SEM 0.62, p < 0.001) significantly increased, triglyceride levels significantly decreased (128.5 vs. 122.1 mg/dL, SEM 3.8, p = 0.048). There was no change in LDL levels. Creatinine levels remained stable throughout the period of rehabilitation. Cardiorespiratory rehabilitation has a significant impact on myocardial function, quality of life in terms of exercise capacity and symptoms (6 MWT) as well as laboratory levels relevant for cardiovascular prevention such as glycemia and lipid profile.
