Abstract: Introduction: The current trend is to improve the quality of life of patients treated by coronary surgery and reduce complications and resources. Objectives: To construct and validate a risk index to predict immediate mortality in myocardial revascularization surgery. Method: Development research was carried out in the Cardiovascular Surgery service of the Cardiology Center of Hospital “Hermanos Ameijeiras”, from March 2012 to 2017, the sample included 340 patients. The investigation work was divided into two phases, the first one for the construction of the instrument and the second for its validation. Results: The logistic regression model had a good calibration given by the Hosmer and Lemeshow analysis (p = 0.914). The final score resulted from multiplying the value of each variable by its weight. The area under the ROC curve for the probability of dying was 0.902 (95% CI: 0.852-0.952). By dividing the calculated probability into three zones, it was observed that the majority of patients with immediate mortality were grouped into high risk.The area under the ROC curve for the quantitative index was 0.869 (95% CI: 0.825– 0.913), showing good discrimination. The intraclass correlation coefficient for the probability-based index was 0.966 (95% CI: 0.955-0.975) and for the quantitative index it was 0.935 (95% CI: 0.913-0.952). Conclusions: The index for the prediction of immediate mortality in myocardial revascularization surgery demonstrates validity and reliability that make it a feasible and useful instrument to be applied.
