FERNANDEZ, Andrés et al. Morbimortality risk score in patients submitted to percutaneous coronary intervention. Rev. Col. Cardiol. [online]. 2008, vol.15, n.2, pp.55-64. ISSN 0120-5633.

The main objective of this observational study was to establish a mortality risk score for intra-hospital morbidity and mortality in patients submitted to percutaneous coronary intervention (PCI) after having suffered one of the following acute coronary syndromes: unstable angina (UA), acute myocardial infarction without ST elevation (NSTEMI) or acute myocardial infarct with ST elevation (STEMI). Clinical and demographic data of 1,300 patients treated in the clinic between 2003 and 2006 were recollected in a retrospective way with the aim of obtaining a valid risk score for the Colombian population. This was realized through a data base of multiple pre-procedure variables (personal antecedents), intra-procedure variables (time elapsed since the arrival to ER to the moment of catheterization and number of diseased vessels among others) and post-procedure variables (morbimortality complications). Data analysis was then performed through a logistic regression model in order to determine which risk factors were statistically significant in causing some of the results evaluated. The principal results evaluated were death, adverse hematological events and hospital stay; after the analysis we found that the main factors related to patients’ morbimortality, were the type of patient (or the type of coronary syndrome suffered), age and homodynamic state at admission (presence of cardiogenic shock). From these results a risk score through pre-procedure, post-procedure and intra-hospital variables was developed.
