title: [Carotid intima-media thickness in the Congolese hypertensive in South Kivu].
abstract: OBJECTIVE
  The present work aims to establish the frequency, determinants, and the influence of the increased carotid intima-media thickness on the assessment of cardiovascular risk in hypertensive Congolese subjects.
  
  
  METHODS
  The carotid intima-media thickness was systematically measured using B-mode ultrasound in 254 hypertensive patients aged≥25years, all native of South Kivu Province. The association between carotid intima-media thickness and various assumed risk factors was modeled in linear and logistic regressions.
  
  
  RESULTS
  In the entire study population, 28% had an increased carotid intima-media thickness (≥0.9mm) and 22.4% a plaque (>1.2mm). Carotid intima-media thickness was significantly correlated only with age (partial r=0.289, P<0.0001) and duration of hypertension (partial r=0.154, P=0.01). In addition, the increase in carotid intima-media thickness was associated with an increased global cardiovascular risk according to the European and Framingham criteria, respectively, and independently, the risk of stroke [fourth cIMT quartile adjusted OR=5.4 (95% CI: 1.6 to 18.3), P=0.0007]. However, carotid intima-media thickness did not significantly influence the cardiovascular risk categorization (P>0.05).
  
  
  CONCLUSIONS
  The increase in carotid intima-media thickness in hypertensive Congolese subjects would be a marker of arterial remodeling associated with a long history of uncontrolled hypertension rather than early atherosclerosis. Its systematic detection would pinpoint those at risk of stroke and optimize their treatment.
