Predictors of cardiorespiratory fitness improvement in phase II cardiac rehabilitation.

ABSTRACT:

Background

Cardiac rehabilitation (CR) improves cardiorespiratory fitness (CRF) and has been shown to reduce cardiovascular events and death. However, data about predictors of fitness improvement during CR are limited and conflicting. The objective of this study was to determine predictors of improvement in metabolic equivalents of task (METs) based on formal exercise testing throughout phase II CR.

Methods

We retrospectively reviewed 20?671 patients enrolled in phase II CR at our center from 2006 to 2016. Patients who completed 36 sessions and had entry and exit exercise stress tests were included for study. The short form-36 (SF-36) questionnaire was used to assess quality-of-life. Univariate and multivariate regression analyses were performed to determine independent predictors of METs improvement.

Results

Of the full cohort, 827 patients completed 36 sessions and had entry/exit stress test data. The majority of patients (N?=?647, 78.2%) had improvement in METs (mean ? 2.0 ± 1.2 METs), including patients ?65 and? 5 METS) both had improvement, with no statistical difference between the groups (P = 0.36).

Conclusions

In a large cohort of phase II CR patients, improvement in CRF was seen in the majority of patients across all ages, genders, and levels of baseline fitness.

Project description:BackgroundPatients who have completed Phase II cardiac rehabilitation have low rates of maintenance of exercise after program completion, despite the importance of sustaining regular exercise to prevent future cardiac events.PurposeThe efficacy of a home-based intervention to support exercise maintenance among patients who had completed Phase II cardiac rehabilitation versus contact control was evaluated.DesignAn RCT was used to evaluate the intervention. Data were collected in 2005-2010 and analyzed in 2010.Setting/participantsOne hundred thirty patients (mean age=63.6 years [SD=9.7], 20.8% female) were randomized to exercise counseling (Maintenance Counseling group, n=64) or contact control (Contact Control group, n=66).InterventionMaintenance Counseling group participants received a 6-month program of exercise counseling (based on the transtheoretical model and social cognitive theory) delivered via telephone, as well as print materials and feedback reports.Main outcome measuresAssessments of physical activity (7-Day Physical Activity Recall), motivational readiness for exercise, lipids, and physical functioning were conducted at baseline, 6 months, and 12 months. Objective accelerometer data were collected at the same time points. Fitness was assessed via maximal exercise stress tests at baseline and 6 months.ResultsThe Maintenance Counseling group reported significantly higher exercise participation than the Contact Control group at 12 months (difference of 80 minutes, 95% CI=22, 137). Group differences in exercise at 6 months were nonsignificant. The intervention significantly increased the probability of participants' exercising at or above physical activity guidelines and attenuated regression in motivational readiness versus the Contact Control Group at 6 and 12 months. Self-reported physical functioning was significantly higher in the Maintenance Counseling group at 12 months. No group differences were seen in fitness at 6 months or lipid measures at 6 and 12 months.ConclusionsA telephone-based intervention can help maintain exercise, prevent regression in motivational readiness for exercise, and improve physical functioning in this patient population.
