A Randomized Trial Comparing Cardiac Rehabilitation to Standard of Care for Adults With Congenital Heart Disease( )

in English and held by 1 WorldCat member library worldwide

Background: Cardiac rehabilitation (CR) improves exercise capacity and quality of life while reducing mortality in adults with acquired heart disease. Cardiac rehabilitation has not been extensively studied in adults with congenital heart disease (CHD). Methods: We performed a prospective, randomized controlled trial (NCT01822769) of a 12-week clinical CR program compared with standard of care (SOC). Participants were e"6 years old, had moderate or severe CHD, had O2 saturation e"2%, and had peak O2 consumption (V ̇ O 2 pk) <80% predicted. We assessed exercise capacity, physical activity, quality of life, self-reported health status, and other variables at baseline and after 12 weeks. The prespecified primary end point was change in V ̇ O 2 pk. Results: We analyzed data on 28 participants (aged 41.1 ± 12.1 years, 50% male), 13 randomized to CR and 15 to SOC. V ̇ O 2 pk averaged 16.8 ± 3.8 mL/kg/min, peak work rate = 95 ± 28 W, and median Minnesota Living with Heart Failure Questionnaire (MLHFQ) score = 27 (interquartile range: 11-44). Cardiac rehabilitation participants were older (48 ± 9 years vs 36 ± 12 years; P = .01), but there were no significant between-group differences in other variables. There were no adverse events related to CR. V ̇ O 2 pk increased in the CR group compared with SOC (+2.2 mL/kg/min, 95% confidence interval: 0.7-3.7; P = .002, age-adjusted +2.7 mL/kg/min; P = .004); there was a nonsignificant improvement in work rate (+8.1 W; P = .13). Among the 25 participants with baseline MLHFQ> 5, there was a clinically important>5-point improvement in 72.7% and 28.6% of CR and SOC participants, respectively (P = .047). Cardiac rehabilitation was also associated with improved self-assessment of overall health (P <.04). Conclusions: Cardiac rehabilitation is safe and is associated with improvement in aerobic capacity and self-reported health status compared with SOC in adults with CHD

Exercise Oscillatory Ventilation in Patients With Fontan Physiology( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract : Background--: Exercise oscillatory ventilation (EOV) refers to regular oscillations in minute ventilation (VE) during exercise. Its presence correlates with heart failure severity and worse prognosis in adults with acquired heart failure. We evaluated the prevalence and predictive value of EOV in patients with single ventricle Fontan physiology. Methods and Results--: We performed a cross-sectional analysis and prospective survival analysis of patients who had undergone a Fontan procedure and subsequent cardiopulmonary exercise test. Data were reviewed for baseline characteristics and incident mortality, heart transplant, or nonelective cardiovascular hospitalization. EOV was defined as regular oscillations for>60% of exercise duration with amplitude>15% of average VE . Survival analysis was performed using Cox regression. Among 253 subjects, EOV was present in 37.5%. Patients with EOV were younger (18.8±9.0 versus 21.7±10.1 years; P =0.02). EOV was associated with higher New York Heart Association functional class (P =0.02) and VE /VCO2 slope (36.8±6.9 versus 33.7±5.7; P =0.0002), but not with peak VO2 (59.7±14.3 versus 61.0±16.0% predicted; P =0.52) or noninvasive measures of cardiac function. The presence of EOV was associated with slightly lower mean cardiac index but other invasive hemodynamic variables were similar. During a median follow-up of 5.5 years, 22 patients underwent transplant or died (n=19 primary deaths, 3 transplants with 2 subsequent deaths). EOV was associated with increased risk of death or transplant (hazard ratio, 3.9; 95% confidence interval, 1.5-10.0; P =0.002) and also predicted the combined outcome of death, transplant, or nonelective cardiovascular hospitalization after adjusting for New York Heart Association functional class, peak VO2, and other covariates (multivariable hazard ratio, 2.0; 95% confidence interval, 1.2-3.6; P =0.01). Conclusions--: EOV is common in the Fontan population and strongly predicts lower transplant-free survival
