Racial differences in the incidence of femoral bypass and abdominal aortic aneurysmectomy in Massachusetts: Relationship to cardiovascular risk factors

摘要: Abstract Purpose: Atherosclerotic disease appears to be more severe in black patients than white patients, but abdominal aortic aneurysms, which have traditionally been believed an atherosclerotic cause, are reported less common patients. Our goals were compare and contrast factors associated with the development of aneurysms clinically significant occlusive (1) determine whether these diseases share a cause (2) explore their association race. Methods: Dual case-control studies conducted multivariate analysis cases (patients undergoing aneurysmectomy or femoral bypass) comparison group consisting who had undergone appendectomy. Two data sources used: hospital discharge for Massachusetts from 1984 through 1988 medical records at University Hospital Boston City Hospital. For both database chart review, obtained all discharged between January December International Classification Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedure code aneurysm resection (38.44) aneurysmorrhaphy (38.34) artery bypass/reconstruction (39.29). To conduct nested study, also control ages 50 84 years appendectomy during same 5-year period. Results: Black higher rates bypass did after adjustment age sex (odds ratio=1.97; 95% confidence interval: 1.49, 2.61; p Conclusions: Hypertension, smoking, male risk atherosclerosis formation. However, occur predominantly men do not appear diabetes mellitus income. In contrast, rate is probably result greater prevalence among hypertension, diabetes, perhaps by other ill-defined socioeconomic status. (J V ASC S URG 1995;21:422-31.)
