Physical Activity After Percutaneous Coronary Intervention for Chronic Total Occlusion and Its Association With Health Status.

ABSTRACT: Background Patients with chronic total occlusion ( CTO ) may not participate in regular exercise because of refractory angina. Exercise participation after percutaneous coronary intervention (PCI) for CTO ( CTO PCI ) and the association of exercise with health status after CTO PCI is unknown. Methods and Results Overall, 1000 patients enrolled in the Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion OPEN CTO is a registry were asked about participation in regular exercise at baseline and 12 months after CTO PCI , and the frequency of exercise (<1, 1-2, ?3 times/week) was collected among exercisers. Health status was assessed using the Seattle Angina Questionnaire ( SAQ ). Multivariable regression assessed 12-month health status change across 4 groups defined by exercise frequency at baseline and 12 months after CTO PCI (no regular exercise at baseline and 12 months, reduced, increased, and consistent exercise at 12 months). Among 869 patients with complete exercise data, the proportion that exercised regularly increased from 33.5% at baseline to 56.6% 12 months after CTO PCI ( P<0.01). Predictors of regular exercise at 12 months included baseline exercise, smoking, baseline and increase in SAQ scores for angina frequency, physical limitation, quality of life, and summary. After multivariable adjustment, consistent or increased exercise frequency was associated with significantly greater improvement in SAQ scores for angina frequency, physical limitation, quality of life, and summary ( P<0.01). Conclusions Participation in regular exercise increased significantly 12 months after CTO PCI , and patients who had greater health status benefit after PCI were more likely to exercise regularly at 12 months. CTO PCI may enable coronary artery disease patients with limiting symptoms to engage in regular exercise and to support better long-term outcomes.

Project description:BackgroundThe development of the technique has improved the success rate of percutaneous coronary intervention (PCI) for in-stent chronic total occlusion (IS-CTO). However, long-term outcomes remain unclear. The present study sought to investigate long-term outcomes of PCI for IS-CTO.MethodsA total of 474 IS-CTO patients were enrolled at two cardiac centers from 2015 to 2018 retrospectively. These patients were allocated into either successful or failed IS-CTO PCI groups. The primary endpoint (major adverse cardiac events [MACE]) consisted of recurrent angina pectoris (RAP), target-vessel myocardial infarction (MI), heart failure, cardiac death, or ischemia-driven target-vessel revascularization (TVR) at follow-up. Multivariable Cox regression analysis was used to investigate the association between treatment appropriateness and clinical outcomes.ResultsA total of 367 patients were successfully treated with IS-CTO PCI while 107 patients had failed recanalization. After a median follow-up of 30 months (interquartile range: 17-42 months), no significant difference was observed between the two groups for the following parameters: cardiac death (successful PCI vs. failed PCI: 0.9% vs. 2.7%; adjusted hazard ratio [HR]: 1.442; 95% confidence interval [CI]: 0.21-9.887; P = 0.709), RAP (successful PCI vs. failed PCI: 40.8% vs. 40.0%; adjusted HR: 1.025; 95% CI: 0.683-1.538; P = 0.905), heart failure (successful PCI vs. failed PCI: 6.1% vs. 2.7%; adjusted HR: 0.281; 95% CI: 0.065-1.206; P = 0.088), target-vessel related MI (successful PCI vs. failed PCI: 1.5% vs. 2.7%; adjusted HR: 1.150; 95% CI: 0.221-5.995; P = 0.868), MACE (successful PCI vs. failed PCI: 44.2% vs. 45.3%; adjusted HR: 1.052; 95% CI: 0.717-1.543; P = 0.797). More patients were free of angina in the successful IS-CTO PCI group compared with failed PCI in the first (80.4% vs. 60%, P < 0.01) and second years (73.3% vs. 60.0%, P = 0.02) following up. Successful IS-CTO PCI had a lower incidence of MACE in the first and second years (20.2% vs. 40.0%, P < 0.01; 27.9% vs. 41.3%, P = 0.023) compared with failed PCI. After a median follow-up of 30 months, the reocclusion rate was 28.5% and TVR was 26.1% in the successful IS-CTO PCI group. Receiving >18 months of dual antiplatelet therapy (DAPT) was an independent predictor of decreased risk of TVR (HR: 2.682; 95% CI: 1.295-5.578; P = 0.008) or MACE (without TVR) (HR: 1.898; 95% CI: 1.036-3.479; P = 0.038) in successful IS-CTO PCI.ConclusionsAfter a median follow-up of 30 months, the successful IS-CTO PCI group had MACE similar to that of the failed PCI group. However, the successful IS-CTO PCI group had improved angina symptoms and were free from requiring coronary artery bypass grafting in the first or second years. To decrease MACE, DAPT was found to be essential and recommended for at least 18 months for IS-CTO PCI.
