Prognostic values for in-hospital event rate of early E/Em in patients with acute myocardial infarction
OBJECTIVE: To assess the prognostic values for in-hospital event rate of tissue Doppler imaging (TDI) parameter (E/Em) after acute myocardial infarction.
METHODS: A total of 289 patients with acute myocardial infarction were retrospectively examined. Their clinical data and echocardiograms were obtained. Clinical events were recorded. Patients were divided into two groups according to the value of ratio of early transmitral flow velocity to early diastolic velocity of mitral annulus (E/Em): Group E/Em < 10 (n = 152) and Group E/Em ≥ 10 (n = 137). Clinical characteristics, echocardiographic parameters and the rate of cardiac events were compared. Predictors of heart failure were identified by multivariate Logistic regression analysis.
RESULTS: On echocardiography, the patients with an E/Em ratio ≥ 10 had statistically larger left atrial diameter [(39.1 ± 6.2) vs (36.0 ± 4.4) mm, P = 0.000] and left ventricular end diastolic diameter [(52.3 ± 7.3)vs (49.2 ± 5.2) mm, P = 0.000]. Worse systolic functions were found in group E/Em ≥ 10: left ventricular ejection fraction (LVEF) [(48.3 ± 11.7)% vs (56.7 ± 9.7)%, P = 0.000]. Systolic velocities of mitral annulus (Sm) [(6.6 ± 1.7) vs (8.6 ± 2.2) cm/s, P = 0.000]. Em [(6.4 ± 1.9) vs (9.4 ± 2.4) cm/s, P = 0.000] was statistically lower than that of E/Em < 10 group. Killip classes on admission were statistically higher in group E/Em ≥ 10 than those of the other group [(1.7 ± 0.9) vs (1.2 ± 0.6), P = 0.000]. So were as the ratio of heart failure (38.5% vs 13.8%, P = 0.000) and in-hospital mortality rate (4.4% vs 0.8%, P = 0.000). Logistic regression analysis demonstrated that the independent risk factors of heart failure included the value of E/Em and LVEF.
CONCLUSION: Early E/Em is probably a powerful predictor for left ventricular remodeling and in-hospital heart failure in patients after acute myocardial infarction.
