ABSTRACT
Objective To investigate the effect of percutaneous eoronary intervention (PCI) on the prognosis of acute ST-segment elevation myocardial infarction (ASTEMI) in the elderly.Methods The 1318 ASTEMI patients in our hospital from June 1998 to June 2008 were retrospectively analyzed. Among them, 338 (25.6%) elderly patients were over 60 years old, and 316patients consistent with inclusion and exclusion criteria were consecutively enrolled in our research.Then they were divided into two groups PCI group (136 cases, 43.0%) and conservative drug treatment group (180 cases, 57. 0%). The clinical data of study objects were collected. Then they were followed up regularly for two years. Results There were no statistically significant differences between the two groups in mean age, gender, hypertension, diabetes, dyslipidemia, excess smoking,wine and family history (all P> 0.05). And there were no statistically significant differences in anterior wall STEMI, Killip Ⅲ-Ⅳ class, thrombolysis therapy and malignant ventricular arrhythmia (all P>0. 05). Most of the objects proceeded therapeutic lifestyle improvements, such as giving up smoking, restricting wine, regulating diet, losing weight and insisting on exercises, and so on.Secondary prevention drugs of acute myocardial infarction including angiotensin converting enzyme inhibitor, angiotensin receptors blockers, beta receptor, aspirin and statins were regularly administrated in the two follow-up years. In the retrospective research, incidence rates of reinfarction, NYHA (New York Heart Association) Ⅲ-Ⅳ class heart function and one-month mortality were much higher in conservative treatment group than in PCI group (17.2% vs. 2. 2%, OR=9. 224,95% CI 2. 756-30. 857; 31.1% vs. 8.1%,OR=5.132, 95%CI 2. 568-10. 257; 8. 3% vs. 1.5%,OR= 6. 091, 95% CI 1. 369-27. 105, respectively; all P < 0. 01). Above all, one and two-year mortalities were much higher in conservative treatment group than in PCI group (21.1% vs. 2. 2 %,OR=11.864, 95%CI 3.577-39.349; 32.2% vs. 4.4%, OR=10.301, 95%CI 4.289-24.736,respectively; all P<0. 01). Conclusions PCI may reduce the re-infarction, NYHA Ⅲ-Ⅳ class heart function and one-month mortality, especially so in view of the one and two-year mortality. PCIcan significantly improve the prognosis of ASTEMI in the elderly.
