Abstract 13083: Multi-Center Study of Risk Factor Status on Entry to a Contemporary Phase 2 Cardiac Rehabilitation Program: Temporal Trends

Abstract

Introduction: No comprehensive data are available on temporal trends in the percentage of participants who are not at recommended ASCVD risk factor goal levels on entry to a contemporary phase 2 cardiac rehabilitation (CR) program and, therefore, in need of intensified risk factor intervention. The purpose of this study was to determine whether improvements have occurred in recent years in the control of multiple risk factors in patients entering CR. Methods: In this multi-center registry, we compared the percentage of participants not at goal for select risk factors on entry to CR during 2000-2004 versus 2005-2009. Subjects were 26,956 consecutive patients (age=63.8 + 11.5 years; males=69.8%; females=30.2%) who enrolled in a phase 2 CR program at 35 centers in the US between 2000 and 2009 and completed an initial evaluation on program entry. Statistical significance of differences between groups was analyzed using chi-square and unpaired t-tests and statistical significance was established at p < 0.05. Results: Percentages of patients with risk factors not at goal levels on entry to CR for the 2000-2004 (n=10,900) and 2005-2009 (n=16,056) cohorts are shown in Figure 1 (*statistically significant difference) . Compared to the 2000-2004 cohort, the percentage of the 2005-2009 cohort not at goal was lower (p<0.001) for BP (goal <120/80 mmHg) and LDL cholesterol (goal <100 mg/dl), higher (p<0.001) for BMI (goal <25 kg/m 2 ), and not significantly different (p>0.05) for smoking (goal=no smoking), fasting glucose (goal <100 mg/dl) and physical activity (goal ≥150 min/wk). Conclusions: These data indicate that while the control of some risk factors has improved significantly over time, the control of others has remained unchanged or worsened. The data further demonstrate that multiple risk factors are often inadequately controlled on entry to contemporary phase 2 CR programs and serve to emphasize the need for intensive risk factor intervention during CR.
