Does Type D Personality Inhibit Benefits of Cardiac Rehabilitation?

Özet

Introduction: Cardiovascular diseases are major causes of mortality and morbidity in the world. D type personality is a poor prognostic factor in cardiovascular diseases. Cardiac rehabilitation is known to reduce mortality and morbidity in cardiovascular diseases. The present study aims to investigate whether type D personality inhibits the benefits of cardiac rehabilitation or not. Methods: A single-center, retrospective cohort study was conducted with the evaluation of all CR participants at the University Hospital of Cardiovascular and Thoracic Surgery between 01.02.2017 and 01.02.2019. Study population was the patients who were 18 years and older and completed all 30 sessions of CR program and also completed both pre- and post-tests. Type D personality was assessed with DS14. Quality of life was assessed with SF 36. Functional capacity was assessed with a 6-minute walk test (6MWT). Submaximal cycle ergometer test was performed to evaluate maximum endurance watts. A special CR program was planned for each patient based on the cycle ergometer test peak workload. The primary endpoint was the observation of changes in the Beck Depression Scale, SF-36 scores and the secondary endpoint of the study was the observation of improvement in functional capacity and endurance according to patients’ type D personality. Results: 222 patients enrolled in this study. Among the patients, 37.4% of them were positive for D type personality. Functional capacity, endurance, quality of life, depression scores were all improved after cardiac rehabilitation (p<0.01). There was no statistically significant difference between D type positive and negative patient groups about the improvements of rehabilitation (p≥0.05). Discussion and Conclusion: D type personality is associated with inflammation and may increase mortality and morbidity in a cardiovascular disease. Cardiac rehabilitation may improve functional capacity, endurance, quality of life and depression scores independently from D Type personality.
