Background-Randomized trials comparing coronary artery bypass graft surgery (CABG) with percutaneous coronary interventions (PCIs) for patients with multivessel coronary disease (MVD) report similar long-term survival for CABG and PCI. These studies used a highly selected population of patients and providers, and their results may not be generalizable to actual care. Our goal in this study was to compare long-term survival of MVD patients treated with CABG vs PCI in contemporary practice.Methods and Results-From our northern New England registries of consecutive coronary revascularizations, we identified 10 198 CABG and 4295 PCI patients with MVD who may have been eligible for either procedure between 1994 and 2001. Vital status was obtained by linkage to the National Death Index. Proportional-hazards regression was used to calculate hazard ratios (HRs) for survival in CABG vs PCI patients after adjustment for comorbidities and disease characteristics. CABG patients were older; had more comorbidities, more 3-vessel disease, and lower ejection fractions; and were more completely revascularized. Adjusted long-term survival for patients with 3-vessel disease was better after CABG than PCI (HR, 0.60; P < 0.01) but not for patients with 2-vessel disease (HR, 0.98; P=0.77). The survival advantage of CABG for 3-vessel disease patients was present in all patient populations, including women, diabetics, and the elderly and in the era of high stent utilization.Conclusions-In contemporary practice, survival for patients with 3-vessel coronary disease is better after CABG than PCI, an observation that patients and physicians should carefully consider when deciding on a revascularization strategy.

OBJECTIVES We sought to determine whether the changing practice of interventional cardiology has been associated with improved outcomes for women, and how these outcomes compare with those for men.BACKGROUND Previous work from the early 1990s suggested women are at a higher risk than men for adverse outcomes after percutaneous coronary interventions (PCIs).METHODS From 1994 to 1999 data were collected on 33,666 consecutive hospital admissions for a PCI in Northern New England. Multivariate models were used to adjust for diffierences in case-mix across year of procedure when comparing outcomes. Direct standardization was used to calculate adjusted rates.RESULTS From 1994 to 1999, the case-mix worsened for both women and men, although women had more co-morbidities than did men throughout the period. Stent use increased over time (> 75% in 1999). Concomitantly, the need for emergency coronary artery bypass graft surgery (CABG) decreased significantly (p(trend) less than or equal to 0.001; in 1999: 0.06% for women, 0.05% for men). Although the emergency CABG rates were higher for women at the beginning of the study, by the end, they were comparable (adjusted odds ratio 1.34, 95% confidence interval 0.76 to 2.38, p = 0.315). The myocardial infarction (MI) rates decreased over time for both women (by 29.7%, p(trend) = 0.378) and men (by 37.6%, p(trend) = 0.009) and did not differ by gender. The mortality rates did not decrease significantly over time and were not significantly different between the genders (mean 1.21% for women, 1.06% for men; p = 0.096).CONCLUSIONS Concurrent with the changing practice of PCI, and despite treating sicker patients, there have been important improvements in post-PCI CABG and MI rates for women, as well as for men. Unlike in earlier years, there are no longer significant differences in outcomes by gender. (C) 2002 by the American College of Cardiology Foundation.

“Ad hoc” percutaneous coronary interventions (PCIs)—those performed immediately after diagnostic catheterization—have been reported in earlier studies to be safe with a suggestion of higher risk in certain subgroups. Despite increasing use of this strategy, no data are available in recent years with new device technology. We studied use of an ad hoc strategy in a large regional population to determine its use and outcomes compared with staged procedures. A database from the 6 centers performing PCIs in northern New England and 1 center in Massachusetts was analyzed. During 1997, excluding only patients requiring emergency procedures or those with a prior PCI, 4,136 PCIs were performed, 1,748 (42.3%) of these being ad hoc procedures. Patients having ad hoc procedures were less likely to have peripheral vascular disease, renal failure, prior myocardial infarction, or coronary artery bypass surgery, congestive heart failure, or poor left ventricular function, and more likely to have received preprocedural intravenous heparin or nitroglycerin or to have required an urgent procedure. Narrowings treated during ad hoc procedures were less frequently types B and C or in saphenous vein grafts. Adjusted rates of clinical success were not different between ad hoc and non-ad hoc procedures (93.7% vs 93.6%); there was no difference in the incidence of death (0.6% vs 0.5%), emergency (0.9% vs 0.8%) or any (1.4% vs 0.8%) coronary artery bypass surgery, or myocardial infraction (2.6% vs 2.0%). As currently practiced in our region, ad hoc intervention is used selectively with outcomes similar for ad hoc and non-ad hoc procedures.

OBJECTIVES:We sought to evaluate the changing outcomes of percutaneous coronary interventions (PCIs) in recent years.BACKGROUND:The field of interventional cardiology has seen considerable growth in recent years, both in the number of patients undergoing procedures and in the development of new technology. In view of recent changes, we evaluated the experience of a large, regional registry of PCIs and outcomes over time.METHODS:Data were collected from 1990 to 1997 on 34,752 consecutive PCIs performed at all hospitals in Maine (two), New Hampshire (two) and Vermont (one) supporting these procedures, and one hospital in Massachusetts. Univariate and multivariate regression analyses were used to control for case mix. Clinical success was defined as at least one lesion dilated to <50% residual stenosis and no adverse outcomes. In-hospital adverse outcomes included coronary artery bypass graft surgery (CABG), myocardial infarction and mortality.RESULTS:Over time, the population undergoing PCIs tended to be older with increasing comorbidity. After adjustment for case mix, clinical success continued to improve from a low of 88.2% in earlier years to a peak of 91.9% in recent years (p trend <0.001). The rate of emergency CABG after PCI fell in recent years from a peak of 2.3% to 1.3% (p trend <0.001). Mortality rates decreased slightly from 1.2% to 1.1% (p trend 0.007).CONCLUSIONS:There has been a significant improvement in clinical outcomes for patients undergoing PCIs in northern New England, including a significant decline in the need for emergency CABG.
