Effect of gender on prognosis following percutaneous coronary intervention for stable angina pectoris and acute coronary syndromes.

Women with non-ST-elevation acute coronary syndromes (NSTACSs) may have better outcomes than men, but the effect of NSTACSs in women undergoing percutaneous coronary intervention (PCI) has not been examined. We performed a prospective, multicenter, cohort study of consecutive patients who underwent PCI for NSTACS and stable angina during 3 National Heart, Lung, and Blood Institute Dynamic Registry recruitment waves (1997 to 2002) to examine the effect of female gender on adverse clinical events after PCI or stable angina for NSTACS. The primary end point was the combined rate of death, myocardial infarction, or rehospitalization for cardiac causes at 1 year. Compared with men with NSTACS (n = 2,124), women (n = 1,338) were older and more often had hypertension, diabetes mellitus, and history of heart failure (p <0.001 for all), whereas multivessel disease was less frequent (p <0.01). Procedural success and in-hospital adverse event rates were similar. Women with NSTACS had the highest 1-year rate of death/myocardial infarction/cardiac rehospitalization compared with women with stable angina pectoris (n = 462) or men (n = 995; women with NSTACS 37.6%, men with NSTACS 29.8%, women with stable angina 29.4%, men with stable angina 27.7%, p <0.001). The higher rate remained after adjustment for differences in baseline characteristics (adjusted hazard ratio 1.37, 95% confidence interval 1.20 to 1.56). Among women, NSTACS conferred a significantly higher risk for adverse events compared with stable angina (adjusted hazard ratio 1.41, p = 0.001), whereas the risk of adverse events was not different in men (adjusted hazard ratio 1.05, p = 0.5). In conclusion, women undergoing PCI for NSTACS have a higher risk of major adverse cardiac events than men or women undergoing PCI for stable angina.

Outcome of percutaneous coronary intervention in unstable angina pectoris versus stable angina pectoris in two different time periods.

Percutaneous coronary intervention (PCI) for unstable angina pectoris (UAP) has traditionally been associated with a higher risk of ischemic complications than that for stable angina pectoris (SAP). However, PCI procedures have evolved, so this study was designed to determine whether PCI for UAP is still associated with less favorable outcomes. In-hospital and 1-year outcomes in Dynamic Registry patients who presented for PCI with UAP (n = 2,994) or SAP (n = 1,457) between 1997 and 2002 were compared. One-year results were also compared with consecutive patients who underwent angioplasty (n = 2,431) from the 1985 to 1986 Percutaneous Transluminal Coronary Angioplasty Registry. Although Dynamic Registry patients with UAP were older and more likely to smoke (p < 0.05), have diabetes mellitus (p = 0.03), or a previous myocardial infarction (p < 0.001), procedural success was higher than in patients with SAP. By 1 year, there was greater risk of death (4.4% vs 2.6%, p < 0.01), death/myocardial infarction (9.9% vs 6.6%, p < 0.001), and death, myocardial infarction, and coronary artery bypass grafting (15.1% vs 11.6%, p < 0.01) in patients with UAP. In patients with UAP, there was no significant difference in adjusted 1-year death and death/myocardial infarction rates when comparing the waves of the Dynamic Registry with those of the Percutaneous Transluminal Coronary Angioplasty Registry, although death/myocardial infarction rates among Dynamic Registry patients were lower. However, in patients with SAP, the adjusted rate for death/myocardial infarction was lower in wave 3, and for death, myocardial infarction, and revascularization, there was a significant decrease in event rates with each successive recruitment period (p < 0.05 for all comparisons). In conclusion, in contradistinction to patients with SAP, death and death/myocardial infarction rates in patients who have undergone PCI for UAP have not significantly decreased over the past 16 years and patients with UAP remain at a greater risk of ischemic events at 1 year compared with patients with SAP.

Recent trends in the percutaneous treatment of chronic total coronary occlusions.

Percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) has a lower success rate than PCI for non-CTO lesions. We sought to determine trends in the treatment of CTOs within the current interventional era. Using 4 sequential recruitment waves of the National Heart, Lung, and Blood Institute Dynamic Registry, we assessed the relative prevalence and success rates in treating CTO (n=371) versus non-CTO (n=4,802) lesions over a 7-year period (1997 to 2004). Characteristics of attempted lesions and factors associated with PCI outcome were evaluated. CTO lesion attempts decreased by 41% over time, from 9.6% (1997 to 1998) to 5.7% (2004, p<0.0001 for trend). More contemporary CTO lesions were longer (22.4 vs 17.0 mm, p=0.006 for trend), had thrombus less often (21.3% vs 35.4%, p=0.03 for trend), and were more often treated with stents (69.8% vs 45.4% p=0.02). The rate of successful intervention for CTO lesions decreased nonsignificantly during this time, from 79.7% to 71.4% (p=0.18). Using multivariable analysis, female gender (adjusted odds ratio 0.42, 95% confidence interval 0.20 to 0.88, p=0.02), and thrombus (adjusted odds ratio 0.31, 95% confidence interval 0.15 to 0.61, p=0.0008) were associated with higher success rates, whereas the presence of severe noncardiac disease (adjusted odds ratio 1.91, 95% confidence interval 1.05 to 3.45, p=0.03) was associated with a higher risk for PCI failure. Recruitment wave and patient age were not independently related to lesion success. In conclusion, during the PCI period of 1997 to 2004, CTO lesions were attempted less frequently and success rates did not increase, indicating a need for new operator techniques or device technologies to treat this important lesion subset by a percutaneous approach.

Recommendation to develop strategies to increase the number of ST-segment-elevation myocardial infarction patients with timely access to primary percutaneous coronary intervention.

Although evidence suggests that primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy in the majority of patients with ST-segment-elevation myocardial infarction (STEMI), only a minority of patients with STEMI are treated with primary PCI, and of those, only a minority receive the treatment within the recommended 90 minutes after entry into the medical system. Market research conducted by the American Heart Association revealed that those involved in the care of patients with STEMI recognize the multiple barriers that prevent the prompt delivery of primary PCI and agree that it is necessary to develop systems or centers of care that will allow STEMI patients to benefit from primary PCI. The American Heart Association will convene a group of stakeholders (representing the interests of patients, physicians, emergency medical systems, community hospitals, tertiary hospitals, and payers) and quality-of-care and outcomes experts to identify the gaps between the existing and ideal delivery of care for STEMI patients, as well as the requisite policy implications. Working within a framework of guiding principles, the group will recommend strategies to increase the number of STEMI patients with timely access to primary PCI.
