title: [Study of echocardiographic parameters of type 2 black African diabetics at high cardiovascular risk. A cross-sectional study of 79 cases in Senegal].
abstract: BACKGROUND
  The discovery of silent myocardial ischemia in a diabetic placed in a logic of secondary prevention. The objectives of this study were to investigate the echocardiographic parameters of type 2 Senegalese diabetics at high cardiovascular risk and identify those that are predictors of silent myocardial ischemia.
  
  
  METHODS
  We conducted a cross-sectional study in 79 diabetic patients at high cardiovascular risk. After clinical examination, we conducted laboratory tests (glucose, creatinine, lipid profile, blood count and blood chemistry panel), ECG, standard echocardiography and dobutamine stress echocardiography looking for silent myocardial ischemia. Data were analyzed using SPSS 17 and echocardiographic parameters determining predictors of silent myocardial ischemia using a multivariate analysis.
  
  
  RESULTS
  Seventy-nine with type 2 diabetics at high cardiovascular risk were assessed, including 56 women. The mean age was 58.8±11.8 years (44-72ans). The abnormalities found in echocardiography were dominated by left atrium dilation (72.2%), increased filling pressures of left ventricle and increased left ventricular mass in 62.02% cases respectively. At stress echocardiography, regional wall motion abnormalities were found in 67.1% of patients. These disorders were significantly more frequent in patients who had a dilated left atrium (P=0.0001), increased filling pressures (P=0.001) and high left ventricular mass (P=0.001).
  
  
  CONCLUSIONS
  In diabetic patients at high cardiovascular risk, the existence of a dilation of the left atrium to left ventricular hypertrophy or increased filling pressures of the left ventricle may indicate a silent myocardial ischemia.
