Validation of the Killip-Kimball Classification and Late Mortality after Acute Myocardial Infarction

Background: The classification or index of heart failure severity in patients with acute myocardial infarction (AMI) was proposed by Killip and Kimball aiming at assessing the risk of in-hospital death and the potential benefit of specific management of care provided in Coronary Care Units (CCU) during the decade of 60. Objective: To validate the risk stratification of Killip classification in the long-term mortality and compare the prognostic value in patients with non-ST-segment elevation MI (NSTEMI) relative to patients with ST-segment elevation MI (STEMI), in the era of reperfusion and modern antithrombotic therapies. Methods: We evaluated 1906 patients with documented AMI and admitted to the CCU, from 1995 to 2011, with a mean follow-up of 05 years to assess total mortality. Kaplan-Meier (KM) curves were developed for comparison between survival distributions according to Killip class and NSTEMI versus STEMI. Cox proportional regression models were developed to determine the independent association between Killip class and mortality, with sensitivity analyses based on type of AMI. Results: The proportions of deaths and the KM survival distributions were significantly different across Killip class >1 (p <0.001) and with a similar pattern between patients with NSTEMI and STEMI. Cox models identified the Killip classification as a significant, sustained, consistent predictor and independent of relevant covariables (Wald χ2 16.5 [p = 0.001], NSTEMI) and (Wald χ2 11.9 [p = 0.008], STEMI). Conclusion: The Killip and Kimball classification performs relevant prognostic role in mortality at mean follow-up of 05 years post-AMI, with a similar pattern between NSTEMI and STEMI patients.

Erstellung einer Blitzschutzrichtlinie für die Produktpalette der FAM im Auftrag der "Gesellschaft für Prozeßautomation mbH" (GPA)"

On the basis of the global use of the FAM installations and systems, their location, type and height, a lightning protection system is required, which protects humans and machines from danger of a lightning. At the beginning the development, the threat and the potential for destruction of lightning are described. Besides the resulting solid normative calculation models and tables are presented. Then, the product portfolio of the FAM is characterized. From this demonstration models are selected; on the one hand a model for the totality of all portable devices and the other hand a model which defines the power plants. Subsequently, the risk management and a strengths and weaknesses analysis are performed. After that, with graphical and mathematical models, these weaknesses as well as the functional equipotential bonding and grounding system and its dimensioning are investigated and solutions are demonstrated. The following is a coordination of lightning protection standard with other directives and standards in order to classify the resulting internal lightning protection and protective measures against electromagnetic pulse and to generate a uniform protection and application platform. Furthermore, problems of the economy of protective circuit is shown and a solution is given. Finally, the indicated possible solutions are replaced by definitions. The main classification and structure of lightning protection directive are shown and exemplarily applied.
