Received on October 6, ; Accepted on June 28, Patients with ST elevation acute myocardial infarction STEMI comprise a heterogeneous population with respect to the risk for adverse events. Primary percutaneous coronary intervention PCI has shown to be better, mainly in high-risk patients. The c-statistics predictive value of the TIMI risk score for mortality was 0.

Primary percutaneous coronary intervention; ST elevation acute myocardial infarction; Score Ce Mexico. Reperfusion therapy, either pharmacological or mechanical, is indicated in patients with ST elevation acute myocardial infarction STEMI with duration of less than 12 hours.

The superiority of primary percutaneous coronary intervention PCI over fibrinolysis has been demonstrated in several studies: However, it has been observed that the benefit of primary PCI is different in each group of patients and the benefit is greatest in those at high risk.

The risk scores applied to patients who are treated exclusively with primary PCI have reported favorable results. We hypothesized that the TIMI risk score applied to patients with STEMI without cardiogenic shock who undergo primary PCI predicts in hospital mortality and also identifies a group of patients at high risk of killlip other adverse events. The information for the analysis was obtained prospectively from the database of escqla Coronary Care Unit of the National Institute of Cardiology in Mexico City, covering the period from October to February The information included demographic data, risk factors, angiographic characteristics, procedures, and in hospital course.

We se those who at escalw had cardiogenic shock and analyzed only those who underwent primary PCI. The TIMI risk score was calculated for each patient using the variables obtained at admission according to the published criteria 8 listed in Table 1.

Mortality during hospitalization was calculated according to the risk score. However, since left ventriculography is not routinely performed during primary PCI in our hospital, the ejection fraction of the left ventricle was taken from echocardiography performed at 24 to 48 hours postprocedure.

In each group, we analyzed the frequency of adverse events during hospital care, including mortality, reinfarction, stroke, heart failure, cardiogenic shock, ventricular arrhythmias, and the presence of the no refow phenomenon.

More than one adverse event could be present in one patient. Analysis was performed with the statistical package SPSS The continuous and discrete variables were expressed as mean and standard deviation SD. Differences were analyzed with Student’s t test to compare two variables and continuous or discrete analysis of variance ANOVA when comparing more than two variables.

Differences were considered significant at a p value of less than 0. Ninety patients were excluded: We analyzed a total of patients whose baseline characteristics are shown in Table 2. The average age of the population was With respect to cardiac function, The distribution of patients according to TIMI score was as follows: The overall in hospital mortality was 6.

The TIMI risk score was highly predictive of in hospital mortality with a c-statistics of 0. All variables included in the TIMI risk score were present with significantly greater frequency in the high-risk group Table 3. Adverse events that occurred in both groups during hospitalization are shown in Table 4.

We observed that mortality was eight-fold higher in the high-risk group than in the low-risk group Other adverse events also occurred more frequently in the high-risk group: The incidence of reinfarction and stroke was low and there were no significant differences between both groups.

There was no difference between the two groups for stent placement A potentially relevant issue in the treatment of patients with STEMI is that this population is highly heterogeneous regarding their risk of adverse events. Thus, their correct stratification becomes essential to evaluate their prognosis and to take accurate therapeutic decisions.

An ideal risk score must be useful, simple and fast to apply to predict prognosis at short and long range. The TIMI risk score for STEMI is a clinical stratification calculated with data obtained at hospital presentation that can easily classify patients into low and high risk.

It was developed using data from patients treated with thrombolytic therapy in a randomized trial and predicts mortality at 30 days. The CADILLAC risk score reportedly has a better predictive value dd mortality at 30 days and one year, but differs from other primary angioplasty risk scores because it includes angiographic parameters such as the presence of three-vessel disease and final TIMI fow, as well as the left oimball ejection fraction determined by ventriculography.

The progress achieved in reducing in hospital mortality in patients with STEMI increases the importance of predicting other postprocedural complications, that may have a strong influence on patient outcomes. In the meta-analysis of Keeley et al. In our results, there was no difference between high and low-risk groups in the incidence of reinfarction and stroke. Although the high-risk group presented all the risk factors mentioned above, it has been observed that suboptimal reperfusion may be present in a large proportion of patients despite the achievement of TIMI 3 fow.

In the meta-analysis by De Luca et al.

We are aware of the relationship between the presence of the no-refow phenomenon and other complications such as increased incidence of fatal arrhythmias and heart failure in patients with STEMI. Most patients developed cardiogenic shock during hospitalization 19 and Lindholm et al. It would be important to identify this group of at-risk patients, as has been done for patients receiving thrombolytic therapy, 21 so that preventive measures could be implemented in an attempt to prevent the development of cardiogenic shock.

The TIMI risk score applied to STEMI patients without cardiogenic shock, undergoing primary PCI, identifies a group of patients at high-risk not only for higher in hospital mortality, but also for other adverse events such as the no-refow phenomenon, heart failure, development of cardiogenic shock, and ventricular arrhythmias.
