Impact of Exercise-Based Cardiac Rehabilitation on the Mid-Term Outcomes of Patients After Acute Myocardial Infarction Treated With Current Acute-Phase Management and Optimal Medical Therapy.

BACKGROUND: Early reported beneficial effects of cardiac rehabilitation (CR) have recently been disputed. The present study aimed to investigate the clinical impact of CR on the mid-term outcomes of patients following ST-segment elevation myocardial infarction (STEMI) treated with currently available management. METHODS: This study reviewed 145 consecutive patients who underwent primary coronary intervention and were discharged without any disability after STEMI during 2013-2015. RESULTS: Among the patients, 66 (45.5%) completed an outpatient CR program (CR group) and 79 were their non-CR counterparts or patients who dropped out of the program (N-D group). There were no between-group differences in patient demographics and clinical profiles, including door-to-balloon times and prescriptions. A total of 27 patients developed major adverse cardiac and cerebrovascular events (MACCE) during follow-up. The MACCE-free survival rates were 88% and 76% in the CR and N-D groups, respectively (log-rank, p=0.04). Cox proportional analysis demonstrated that inclusion in the N-D group was a significant predictor of MACCEs (HR, 2.36; 95% CI, 1.07-5.74; p=0.03). In the CR group, peak oxygen consumption and ventilatory efficiency determined by cardiopulmonary exercise testing significantly improved after the program (p<0.01). CONCLUSIONS: The impact of CR on the mid-term prognosis of patients with STEMI, even in the current myocardial infarction management era, was beneficial.

Prevalence and significance of sleep disordered breathing in adolescent athletes.

Sleep disordered breathing (SDB) was more prevalent in adolescent athletes than expected, and several potential warning signs related to autonomic nerve activity appeared in SDB athletes. SDB screening may prevent associated downstream risks in the future. http://ow.ly/GQqK30nGm8r.
