title: [Effects of thrombolysis on left and right ventricular diastolic function in patients after myocardial infraction. One-year follow-up].
abstract: It has been shown, that successful reperfusion of the infarctrelated artery by thrombolysis can prevent left ventricular (LV) dilatation and dysfunction. To date no study has shown the impact of thrombolytic therapy on LV and RV diastolic filling. The aim of the study was to assess the effects of thrombolysis on LV and RV diastolic inflow and systolic function of LV in patients (pts) after anterior myocardial infarction MI.
  
  
  METHODS
  Echocardiographic and Doppler-derived measurements of LV systolic function, RV and LV diameters and diastolic function at rest and after treadmill exercise test (TET) were assessed prospectively in 21 patients (pts) after MI treated with streptokinase and 10 pts treated without thrombolysis during one-year follow-up. They were compared with 31 age-matched controls.
  
  
  RESULTS
  LV and RV filling indices in both groups of pts after MI were impaired compared to controls but in pts without thrombolysis were more abnormal compared to pts treated with thrombolysis. Among several echocardiographic variables most consistent alteration was shortening of E-deceleration time of mitral as well as RV inflow, more abnormal in pts without thrombolysis. There was strong inverse relation between degree of impairment of diastolic variables and exercise capacity.
  
  
  CONCLUSIONS
  These data indicates beneficial effect of thrombolysis on RV and LV diastolic function in patients after AMI. E-deceleration was the most sensitive marker of diastolic dysfunction.
