title: [Right ventricular remodeling after myocardial infarctions of different location].
abstract: OBJECTIVE
  To study dynamic dimensional and functional changes of both ventricles after myocardial infarctions (MI) of different locations.
  
  
  METHODS
  Patients with first acute ST elevation MI (n=180) were distribution to 3 groups: anterior (AMI), inferior (IMI), and posterolateral (PLMI). EchoCG dimensional parameters of LV and RV as well as functional two dimensional EchoCG, flow and tissue doppler parameters were measured on days 7, 90 and after 1 year of follow up to reveal systolic or diastolic dysfunction of both chambers.
  
  
  RESULTS
  After 1 year of follow up significant LV remodeling with systolic and diastolic dysfunction was observed in AMI compared with IMI and PLMI. Pronounced RV remodeling was revealed in acute stage of IMI, compared with AMI and PLMI. Dynamic follow up showed reversed RV remodeling in IMI with relative restoration of systolic and diastolic parameters, and progressive RV remodeling in AMI with significant systolic and diastolic dysfunction compared with IMI and PLMI.
  
  
  CONCLUSIONS
  Thus, dynamic structural and functional changes occurr in both ventricles and depend on Ml site, with most ventricular compromise in AMI due to asynergy of the septum, as common ventricular wall plays major role in RV performance.
