Cardiac rehabilitation in women; comparison of enrollment, adherence and outcomes between heart failure and coronary artery disease.

BACKGROUND: There is paucity of data on cardiac rehabilitation (CR) enrollment and outcomes in women with heart failure (HF). METHODS: In this retrospective analysis, we compared enrollment, adherence and outcomes between women with HF versus coronary artery disease (CAD)-related indications referred to a university-affiliated CR program from June 2014-July 2018. A multivariate regression analysis was performed to adjust for imbalanced variables at baseline and baseline value of each outcome to compare change in outcomes between HF and CAD groups RESULTS: A total of 538 women (HF=63 vs CAD=475) were included in the study. At baseline, women with HF were younger, had lower attendance to CR intake and worse perceived health, higher AACVPR risk category and lower exercise capacity but had similar enrollment, weight and dieatry habits when compared to women with CAD. Adjusted analyses showed that almost all cardiac rehabilitation outcomes except for positive affect (anxiety, depression symptoms, negative affect, dietary habits, perceived physical and mental health summary scores, exercise duration and capacity) improved significantly from baseline and in a similar fashion in both groups. Weight loss was significantly greater for women with CAD versus those with HF (CAD: Δ -1.12 ± 2.23 kg versus HF: Δ -0.66 ± 2.78 kg, p = 0.03). CONCLUSION: Despite a lower attendance to CR intake, lower perceived physical health and higher baseline AACVPR risk in women with HF, they have similar CR enrollment, adherence and completion rates compared to women with CAD. Both groups showed significant but similar improvements from baseline in almost all cardiac rehabilitation outcomes. These findings should alert cardiology providers to help overcome obstacles for women with HF to attend CR intake.

Comparison of phase 2 cardiac rehabilitation outcomes between patients after transcatheter versus surgical aortic valve replacement.

Background Referral rates and outcomes of cardiac rehabilitation have not been evaluated in patients with transcatheter aortic valve replacement or compared with surgical aortic valve replacement. Method A retrospective cohort study was conducted in 488 patients who underwent transcatheter aortic valve replacement ( n = 199) and surgical aortic valve replacement ( n = 289) from a university-based statewide transcatheter aortic valve replacement/surgical aortic valve replacement program during 2015-2017. Cardiac rehabilitation consisted of supervised exercise, diet education, and stress and depression management. We compared changes from baseline in exercise duration and intensity during cardiac rehabilitation sessions, quality-of-life (36-Item Short-Form Health Survey), and psychosocial measures (anxiety, depression, mood, social support, and diet) between transcatheter aortic valve replacement and surgical aortic valve replacement patients using t-test and chi-square analyses. Results Of 488 patients, cardiac rehabilitation referral rates were similar at 41% (transcatheter aortic valve replacement 81/199 versus surgical aortic valve replacement 117/289), but enrollment rates were lower in transcatheter aortic valve replacement (27/199, 14%) versus surgical aortic valve replacement (102/289, 35%, p < 0.01). Among eligible patients, cardiac rehabilitation completion rates were lower in transcatheter aortic valve replacement (12%) than surgical aortic valve replacement (32%). Exercise intensity during cardiac rehabilitation improved in both groups in a similar fashion (transcatheter aortic valve replacement 1.03 ± 1.09 versus surgical aortic valve replacement 1.34 ± 1.15 metabolic equivalents), but increase in exercise duration was higher in transcatheter aortic valve replacement patients versus surgical aortic valve replacement patients (14.52 ± 6.42 versus 10.67 ± 8.38 min, p = 0.02). Improvement in physical composite score was higher in surgical aortic valve replacement versus transcatheter aortic valve replacement (8.72 ± 7.87 versus 2.36 ± 7.6, p = 0.02) while improvement in mental composite score was higher in transcatheter aortic valve replacement (8.19 ± 8.50) versus surgical aortic valve replacement (1.18 ± 7.23, p = 0.02). There was no significant difference between the two groups in improvement in psychosocial measures. Conclusion Cardiac rehabilitation enrollment was low in transcatheter aortic valve replacement patients versus surgical aortic valve replacement patients despite similar referral rates. Improvement in functional and quality-of-life performance was achieved in both transcatheter aortic valve replacement and surgical aortic valve replacement. Future studies should address obstacles for enrollment of transcatheter aortic valve replacement patients.

Safety and Outcomes of Cardiac Rehabilitation for Patients with Spontaneous Coronary Artery Dissection.

OBJECTIVE: To evaluate the safety and outcomes of aerobic and resistance training in patients undergoing cardiac rehabilitation after spontaneous coronary artery dissection. METHODS: Eleven patients with spontaneous coronary artery dissection at 2 academic centres were studied retrospectively during cardiac rehabilitation from July 2013 to September 2017. Patients underwent maximal effort exercise testing at enrollment and discharge per institutional protocol. Patients were prescribed individualized exercise regimens based on stress test results, stress management with a behavioural psychologist, and diet counselling with a nutritionist. Resistance training was introduced during weeks 3-5 with close blood pressure monitoring. RESULTS: Ten patients who completed cardiac rehabilitation showed improvements in aerobic exercise capacity and exercise duration. For resistance training, patients increased the total number of resistance exercise modalities, repetitions, or both. After cardiac rehabilitation, significant improvements were found in exercise capacity, Mental Composite Score, Physical Composite Score, anxiety measured by Generalied Anxiety Disorders (GAD-7), and positive affect. During a mean followup of 14 months, no patients had any recurrent dissection or major adverse cardiac events. CONCLUSION: Cardiac rehabilitation is safe and improves functional status, anxiety, positive affect and quality of life in patients with spontaneous coronary artery dissection. Future studies should explore ways to further improve the psychosocial and functional status of these patients.
