Ten-year outcomes of patients randomized to surgery, angioplasty, or medical treatment for stable multivessel coronary disease: effect of age in the Medicine, Angioplasty, or Surgery Study II trial.

With progressive aging, coronary artery disease has been diagnosed at more advanced ages. Although patients aged 65 years or more have been referred to surgical or percutaneous coronary interventions, the best option for coronary artery disease treatment remains uncertain. The current study compared the 3 treatment options for coronary artery disease in patients aged 65 years or more and analyzed the impact of age in treatment options. Patients were separated according to age: 65 years or more (n = 200) and less than 65 years (n = 411). All patients were followed for 10 years. The rates of overall mortality, acute myocardial infarction, and new revascularizations were analyzed. Of 200 patients aged 65 years or more, 68 were randomized to medical therapy, 68 were randomized to percutaneous coronary intervention, and 64 were randomized to coronary artery bypass grafting. At 10 years, overall survival was 63% (medical therapy), 69% (percutaneous coronary intervention), and 66% (coronary artery bypass grafting) (P = .93). The survival free of combined events was 43% (medical therapy), 38% (percutaneous coronary intervention ), and 66% (coronary artery bypass grafting) (P = .007). The survival free of myocardial infarction was 82% (medical therapy), 77% (percutaneous coronary intervention), and 90% (coronary artery bypass grafting) (P = .17), and survival free of new revascularizations was 59% (medical therapy), 58% (percutaneous coronary intervention ), and 91% (coronary artery bypass grafting) (P = .0003). When the 2 age groups were compared, survival free of myocardial infarction for patients treated by percutaneous coronary intervention was 77% (older patients) and 92% (younger patients) (P = .004). In this analysis, treatment options for patients aged 65 years or more who have coronary artery disease yield similar overall survival. However, coronary artery bypass grafting was associated with fewer coronary events, and percutaneous coronary intervention was associated with a higher incidence of myocardial infarction.

Long-term follow-up of a randomized, controlled clinical trial of three therapeutic strategies for multivessel stable coronary artery disease in women.

Coronary artery disease is the leading cause of death in women. The proposed treatments for women are similar to those for men. However, in women with multivessel stable coronary artery disease and normal left ventricular function, the best treatment is unknown. A post hoc analysis of the MASS II study with 10 years of follow-up, mean (standard deviation) 6.8 (3.7) years, enrolled between May 1995 and May 2000, evaluated 188 women with chronic stable multivessel coronary artery disease who underwent medical treatment, percutaneous coronary intervention or coronary artery bypass graft surgery. Primary end-points were incidence of total mortality, Q-wave myocardial infarction, or refractory angina. Data were analysed according to the intention-to-treat principle. Women treated with percutaneous coronary intervention and medical treatment had more primary events than those treated with coronary artery bypass graft surgery, respectively, of 34, 44 and 22% (P = 0.003). Survival rates at 10 years were 72% for coronary artery bypass graft surgery, 72% for percutaneous coronary intervention and 56% for medical treatment (P = 0.156). For the composite end-point, Cox regression analysis adjusted for age, diabetes, hypertension, treatment allocation, prior myocardial infarction, smoking, number of vessels affected and total cholesterol, had a higher incidence of primary events with medical treatment than with coronary artery bypass graft surgery [hazard ratio (HR) = 2.38 (95% confidence interval (CI): 1.40-4.05); P = 0.001], a lower incidence with percutaneous coronary intervention than with medical treatment [HR = 0.60 (95% CI: 0.38-0.95); P = 0.031] but no differences between coronary artery bypass graft surgery and percutaneous coronary intervention. Regarding death, a protective effect was observed with percutaneous coronary intervention compared with medical treatment [HR = 0.44 (95% CI: 0.21-0.90); P = 0.025]. Percutaneous coronary intervention and coronary artery bypass graft surgery compared with medical treatment had better results after 10 years of follow-up.

Ischemia change in stable coronary artery disease is an independent predictor of death and myocardial infarction.

The aim of this study was to evaluate the independent prognostic significance of ischemia change in stable coronary artery disease (CAD). Recent randomized trials in stable CAD have suggested that revascularization does not improve outcomes compared with optimal medical therapy (MT). In contrast, the nuclear substudy of the COURAGE (Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation) trial found that revascularization led to greater ischemia reduction and suggested that this may be associated with improved unadjusted outcomes. Thus, the effects of MT versus revascularization on ischemia change and its independent prognostic significance requires further investigation. From the Duke Cardiovascular Disease and Nuclear Cardiology Databanks, 1,425 consecutive patients with angiographically documented CAD who underwent 2 serial myocardial perfusion single-photon emission computed tomography scans were identified. Ischemia change was calculated for patients undergoing MT alone, percutaneous coronary intervention, or coronary artery bypass grafting. Patients were followed for a median of 5.8 years after the second myocardial perfusion scan. Cox proportional hazards regression modeling was used to identify factors independently associated with the primary outcome of death or myocardial infarction (MI). Formal risk reclassification analyses were conducted to assess whether the addition of ischemia change to traditional predictors resulted in improved risk classification for death or MI. More MT patients (15.6%) developed ≥5% ischemia worsening compared with those undergoing percutaneous coronary intervention (6.2%) or coronary artery bypass grafting (6.7%) (p < 0.001). After adjustment for established predictors, ≥5% ischemia worsening remained a significant independent predictor of death or MI (hazard ratio: 1.634; p = 0.0019) irrespective of treatment arm. Inclusion of ≥5% ischemia worsening in this model resulted in significant improvement in risk classification (net reclassification improvement: 4.6%, p = 0.0056) and model discrimination (integrated discrimination improvement: 0.0062, p = 0.0057). In stable CAD, ischemia worsening is an independent predictor of death or MI, resulting in significantly improved risk reclassification when added to previously known predictors.
