N2 - BACKGROUND: Although risk stratification after acute myocardial infarction (AMI) often is focused on systolic left ventricular (LV) function, it appears that a more complete study of ventricular function including assessment of LV filling would be useful. Doppler echocardiography allows assessment of LV filling, and with the use of the Tei index (sum of isovolumic relaxation and contraction times divided by ejection time), a global estimate of ventricular function may be obtained. Therefore, the aim of this study was to determine the prognostic importance of LV systolic, diastolic, and overall LV function in a large consecutive population with AMI. METHODS: Echocardiography was performed within 6 days of AMI. LV systolic, diastolic, and global function was assessed by means of wall motion index (WMI), mitral flow pattern, and Tei index. The primary end point was all-cause death. RESULTS: Of 799 enrolled patients, 197 died during a median follow-up of 34 months. In a multivariate model including WMI and clinical parameters, WMI had important prognostic information. When mitral filling pattern and quartiles of Tei index were added to the model, restrictive filling (mitral deceleration time <140 ms) was associated with a risk ratio of 1.9 (95% CI 1.3-2.7, P <.0001, Tei index values of >0.68/0.56-0.68/0.46-0.55/<0.46 were associated with risks of 4.0 [2.1-6.9]/2.3 [1.5-3.9]/2.1 [1.2-3.6]/1.0, P <.001). In this model, WMI had no prognostic value (P =.18). CONCLUSIONS: Mitral deceleration time and the Tei index have independent and important prognostic value after AMI.
