Does baseline peak respiratory exchange ratio influence the effects of 6 weeks of cardiac rehabilitation in patients with acute coronary syndrome?
Does baseline peak respiratory exchange ratio influence the effects of 6 weeks of cardiac rehabilitation in patients with acute coronary syndrome?
This study investigates whether baseline peak respiratory exchange ratio during exercise testing can predict the efficacy of cardiac rehabilitation in patients with acute coronary syndrome.
Answers are grounded in this paper and cite their sources.
Baseline peak RER should not yet guide cardiac rehabilitation in ACS; leaves open its predictive value in prospective studies.
Objective To compare and analyze the effects of cardiac rehabilitation (CR) in two groups based on the peak respiratory exchange ratio (RER peak ) 1.1 values using the exercise tolerance test (ETT) results, and to investigate the reasons for early termination of ETT. Methods Patients with acute coronary syndrome who participated in CR exercise training were selected and all subjects underwent 6 weeks of CR exercise training. ETT was performed on a treadmill using a Modified Bruce Protocol before and after CR exercise training. According to the result of the first ETT, the subjects were divided into two groups: those with an RER peak 1.1 (n=33) and those with an RER peak <1.1 (n=22). We investigated the reasons for ETT termination and compared the effect of CR between the groups.
