Target organ involvement in hypertensive patients in Eastern Sudan

Hypertension has become a major cause of cardiovascular morbidity and mortality in both the developed and the developing nations. In a cross-sectional study we assessed the state of blood pressure (BP) control and the pattern of target organ complications in 198 Sudanese patients treated in a teaching hospital in Kassala town in Eastern Sudan, (mean age 53 years, 76% women). Excellent BP control (BP < 140/90 mmHg) was achieved in 46% of the patients. Stage 2 or Stage 3 target organ involvement, particularly albuminuria and ischaemic heart disease, were detected in one-third of the patients. These complications were found to be related to both the severity and the duration of hypertension as well as to the frequency of cigarette smoking. Factors such as poor compliance, adverse socioeconomic status, as well as obesity and cigarette smoking may account for poor BP control and hence the development of hypertensive complications. We conclude that optimal BP control is not yet achieved in the majority of hypertensives in the Sudan. Reasons for this failure should be identified and corrected in order to avoid hypertensive target organ damage.
