Haematological, lipid profile and other biochemical parameters in normal and hypertensive subjects among the population of the eastern province of Saudi Arabia.
OBJECTIVE: To determine the lipid profile complete blood count and other biochemical parameters in normotensive and hypertensive individuals. DESIGN: Cross-sectional population-based epidemiological household survey. SETTING: Population sample of the Eastern Province of Saudi Arabia. RESULTS: Hypertensive individuals had significantly higher mean levels of glucose, Tc, LDL-c, HDL-c, triglycerides and HBAIc, compared to normotensive individuals while there were no significant difference in the mean levels of Apo AI and Apo B. Within the same group there were variations in the levels of certain parameters between male and female. While the mean levels of haemoglobin, WBC and platelets were significantly higher in the hypertensive group compared to normotensive, there were no significant differences between these two groups in the levels of RBC, MCV, HCT, MCH and MCHC. However, the mean levels haemoglobin, RBC count and HCT were significantly higher in male compared to female within the same group with no significant difference in levels of WBC, MCV, MCH and MCHC. Furthermore, the mean concentration of platelets was significantly higher in females compared to male within the same group. Hypertensive individuals had significantly higher serum sodium, chloride and calcium levels but a significantly lower potassium level when compared to normotensive with no siginificant differences between male and female within the same group. CONCLUSION: The lipid and electrolyte profile of hypertensive individuals differ from that of normotensive individuals in this population. This study has contributed towards establishing the normal values for a number of parameters involved in the aetiology of cardiovascular diseases in the population of Eastern province.
