Background: Cardiac Rehabilitation (CR) is a comprehensive program that involves medical evaluation, exercise prescription, lifestyle modification, patient education and counselling. Systematic reviews and meta-analyses have shown that it improves exercise tolerance, quality of life and decrease hospitalization rates in patients with Heart Failure (HF). This study is a pioneer study to determine the factors associated with the outcome of HF patients enrolled in a Cardiac Rehabilitation Program.
Method: This is a cross sectional study of patients > 19 years old with HF of any etiology enrolled in a Cardiac Rehabilitation Program from January 2010 to June 2016. The following data were obtained: (a) demographics, (b) clinical factors, (c) ejection fraction, (d) functional treadmill exercise test (TET), and (e) exercise program parameters. Primary outcome were re-hospitalization and mortality at 6 months to 1 year of follow-up.
Results: There were 76 patients included where 5 patients had re-hospitalizations with no mortalities noted. Data identified six statistically significant factors that are associated with outcome: (1) functional capacity, (2) referring physician, (3) history of stroke, (4) valve and myocardium structural defect etiology of HF, (5) diastolic blood pressure response, and (6) presence of complications during TET.
Conclusion: The patient's poor functional capacity, referring physician, history of stroke, and presence of complications during TET are important parameters in identifying patients who need closer attention to improve their outcomes. And a patient with valve and myocardium structural defect etiology of HF is protective while having a normal diastolic BP response on TET is inconclusive.
