Chart review was performed to obtain demographic, clinical and procedural data. PMI was defined as Creatine Kinase MB > 3 × upper reference limit of normal. Multivariate logistic regression was used to ascertain relationship of PGW use with PMI.RESULTS Two hundred and ninety-three patients(age 63.5 ± 12.3 years; 33.8% diabetic) were included in the study. Eighty point two percent(n = 235) were true bifurcation lesions use of PGW was associated with PMI on univariate analysis(OR = 4.1; P = 0.002). This association remained significant after adjusting for other possible risk factors(OR = 3.5; P = 0.02).CONCLUSION Our results suggest that PGW use for side branch protection may be associated with PMI. Randomized studies are needed to validate these findings.展开更多

Often, legal claims of medical negligence and §1983 based on deliberate indifference by the correctional officials follow. Unique stable and dynamic factors and circumstances and their interaction explain most suicides. A systematic suicide screening using a well-designed suicide screening questionnaire that captures known risk factors will identify most inmates at risk if adequately used. Identification and subsequent mental health assessment set the stage for preventive intervention, monitoring, and treatment of the inmates. A multidimensional suicide prevention program saves not only lives but also the best defense against a liability lawsuit.展开更多
