چکیده

BACKGROUND This study aimed to investigate whether there were sex differences in in-hospital and long-term outcomes for elderly patients over 75 years of age undergoing percutaneous coronary intervention for coronary heart disease. METHODS Consecutive patients aged ≥75 years who underwent percutaneous coronary intervention at a single center in the People's Republic of China from January 2005 to December 2010 were included in this cohort study. Clinical characteristics and in-hospital and long-term outcomes were compared between men and women. RESULTS A total of 465 patients (34.8% women, mean age 78.5±3.2 years) were recruited. Men had a higher prevalence of ST elevation myocardial infarction but were less likely to have heart failure than women (P<0.05). Similar rates of successful in-hospital procedures and deaths were observed in men and women. After a mean follow-up of 3 years, no significant differences were observed between men and women in mortality (12.5% versus 8.0%, P=0.151), myocardial infarction (1.4% versus 2.7%, P=0.368), target vessel revascularization (6.1% versus 4.7%, P=0.540), or cerebral vascular disease (7.9% versus 6.0%, P=0.472). Cox proportional hazards analysis revealed that sex was not independently associated with either in-hospital mortality or long-term mortality. CONCLUSION In elderly patients over 75 years of age, sex influences the prognosis after percutaneous coronary intervention for coronary heart disease.

Comparison of in-Hospital Outcome after Percutaneous Coronary Intervention Between Patients with Anterior Myocardial Infarction and Those With or Without Ramus Intermedius

Introduction: Primary percutaneous coronary intervention (PPCI) is used for the treatment of ST segment elevation myocardial infarction (STEMI). Anterior STEMI is associated with adverse outcomes, and it is possible that the presence of ramus intermedius (RI) would inversely affect the outcome. This research involved the evaluation of the influence of RI presence on clinical ou...
