Physical training after percutaneous coronary intervention in patients with stable angina: effects on working capacity, metabolism, and markers of inflammation.

ObjectivePhysical activity is effective in primary and secondary prevention of cardiovascular disease. In this study, we tested the hypothesis that exercise training improves glucose and lipid metabolism, the inflammatory/anti-inflammatory balance, and the outcome of elective percutaneous coronary intervention (PCI) in patients with stable coronary disease.MethodsSixty-two patients scheduled to undergo PCI for stable angina were randomized to intensive physical activity (n = 33) consisting of home-based exercise on a bicycle ergometer or maintain their usual sedentary life (n = 29). The training program started 2 months before PCI and terminated 6 months afterwards. Clinical examination, blood sampling (fasting glucose, glycated hemoglobin, lipid profile, apolipoprotein B, apolipoprotein A1, C-reactive protein, serum amyloid A, interleukin-6, interleukin-8, and interleukin-10), and maximal exercise tests were performed at inclusion, 1 week before PCI, and 3 and 6 months afterwards.ResultsFifty-six patient...
