- Abstract: Exercise training is reported to have beneficial effects on both lipid profile and exercise capacity in patients with coronary artery disease. In this retrospective study, we investigated the association between the effect of phase II cardiac rehabilitation (CR) on lipid profile and that on exercise capacity in patients with acute coronary syndrome (ACS). We analyzed 104 consecutive patients with ACS on statin therapy (age 62 ± 8 years, men 86) who received phase II CR after successful percutaneous coronary intervention (PCI). We examined lipid measurements and cardiopulmonary exercise test results before and after phase II CR. After 4 months of phase II CR, percentage of predicted aerobic threshold (%AT) based on age and gender significantly increased from 67 ± 11% to 76 ± 12% (p＜0.001), high-density lipoprotein cholesterol (HDL-C) significantly increased from 41.5 ± 11.8mg/dL to 51.4 ± 12.6mg/dL (p＜0.001), and ratio of lowdensity lipoprotein cholesterol to HDL-C (LDLC/HDLC) significantly decreased from 2.3 ± 0.8 to 1.8 ± 0.6 (p＜0.001). A positive correlation was found between change in HDLC and change in %AT (r = 0.463), as well as between percent change in HDLC and percent change in %AT (r = 0.485). A negative correlation was found between change in LDLC/HDLC ratio and change in %AT (r =－0.379), as well as between percent change in LDLC/HDLC ratio and percent change in %AT (r =－0.374). Multiple regression analysis showed that change in %AT was the only factor associated with both change in HDLC and change in LDLC/HDLC and that percent change of %AT was the only factor associated with both percent change in HDLC and percent change in LDLC/HDLC ratio. In conclusion, improvement of lipids profile was correlated with improvement of %AT in phase II CR for patients with ACS on statin therapy after successful PCI.
