title: [The echocardiography in cardiac remodeling after acute myocardial infarction].
abstract: OBJECTIVE
  The goal of this study was to assess the impact of left ventricular diastolic filling on remodeling and survival after acute myocardial infarction.
  
  
  METHODS
  We studied 36 patients with first acute myocardial treated with thrombolytic agents. A Doppler echocardiography was performed at 24 hours, 30 and 90 days after infarction. It measured the relation between E and A waves peak velocities (E/A ratio) and of the E deceleration time (EDT, ms), as well as the flow propagation velocity using color mode M and the E'-wave by tissular Doppler at the lateral mitral ring.
  
  
  RESULTS
  Patients were divided into three groups. Group I, restrctive filling (deceleration time < 140 ms, E/FPV > or = 2, E/A> 2 and E/E' > 15). Group II, elevated filling pressure (deceleration time > or = 140 ms, E/FVP > or = 2, E/A 1,2 and E/E' < or = 15). Group III, normal filling pressure (deceleration time > or = 140 ms, E/FVP < 2, E/A < 1 and E/E' < 15). The E/FPV showed a better correlation in the group with restrictive filling and left ventricular filling pressure was significantly greater than in the group with normal filling pressure at 90 days (2.18 +/- 0.90 vs. 1.5 +/- 0.35; r = 0.99; P = .0001). The end diastolic volume (EDV) was similar in the three groups 24 hours after infarction. EDV varied at 90 days after infarction in those patients that underwent successful coronary angioplasty. Group I, 142.48 +/- 32 vs. 112.48 +/- 32, r = 573; P < .0001).
  
  
  CONCLUSIONS
  E/FVP, using color M-mode Doppler echocardiography, estimates left ventricular filling pressure and predicts left ventricular dilation after acute myocardial infarction.
