Doppler transmitral flow pattern is an independent prognostic factor in acute myocardial infarction.
We analyzed the transmitral flow pattern on admission in 95 patients with acute myocardial infarction. Nineteen patients had a restrictive pattern, defined as a peak early to peak atrial filling wave ratio greater than 1.6, plus an early wave deceleration time shorter than 180 ms. Restrictive pattern, compared with nonrestrictive one, was associated with the development of heart failure (42 versus 11%, p = 0.001) and greater in-hospital mortality (32 versus 7%, p = 0.002). After multivariate analysis, it remained significantly predictive of death (p = 0.028). We conclude that a restrictive pattern of left ventricular filling in patients with acute myocardial infarction is an independent predictor of early outcome.
