AB  - BACKGROUND: Right ventricular (RV) involvement in patients with ST elevation 
      myocardial infarction (STEMI) is a clinically important problem. The aim of this 
      study was to evaluate the use of tricuspid annular velocity assessed by Doppler 
      tissue imaging (DTI) as a marker of RV involvement in patients with a first 
      STEMI. METHODS: Seventy-one patients with a first STEMI were examined by 
      echocardiography before discharge and after 6 months. The patients were compared 
      to 31 healthy subjects (HS). The diagnosis of RV infarction was based on the 
      presence of >or= 1 mm ST elevation in the right precordial ECG lead V4R. 
      Tricuspid annular systolic and diastolic velocities using pulsed-wave DTI were 
      recorded at the RV free wall. RESULTS: At day 1, tricuspid annular velocities 
      were significantly reduced in patients with, compared to those without, ST 
      elevation in V4R (11.1 vs. 13.7 cm/sec, 9.4 vs. 13.1 cm/sec and 14.1 vs. 15.9 
      cm/sec for systolic, early, and late diastolic velocities, respectively; P < 
      0.01). With a cutoff value for a tricuspid annular systolic velocity of 13 
      cm/sec, sensitivity and specificity for identifying patients with ST elevation in 
      V4R were 89% and 71%, respectively. After 6 months, both tricuspid annular 
      systolic and diastolic velocities in patients with RV infarction had increased 
      significantly, but only tricuspid annular systolic velocity was still reduced 
      compared to HS (12.3 vs. 14.7 cm/sec; P < 0.01). CONCLUSION: Tricuspid annular 
      velocities assessed by DTI may be used as a marker of RV involvement in the acute 
      and the late phase after a first STEMI.
