Complete Blood Count (CBC) Status among Hypertensive Subjects in Isiala Mbano, Imo State, South East, Nigeria

Aim: The Complete Blood Count (CBC) among hypertensive subjects in Isiala Mbano, Imo State, Nigeria West Africa were studied.

Methodology: The American College of Cardiology/American Heart Association (2017) current definition of hypertension was used to ascertain, diagnoses and assigned eighty (80)hypertensive subjects after three different consecutive blood pressure check into tests groups. Other blood pressure measures such as pulse pressure and mean arterial pressure were calculated appropriately. Venous blood samples were collected with 5mls syringe and immediately emptied into EDTA container for complete blood count analysis.

Results: The results showed increase in RBC count, HB, PCV and decrease in MCV among hypertensive subjects compared with normotensive subjects. It was statistically insignificant in all age groups. No changes were seen in MCHC and MCH. The results also, showed increase in PLTS count. The increase in PLTS count was statistically significant at P<0.05 and <0.001 among hypertensive age groups 36-65yrs and >66yrs respectively. Increase in PLTS count among 20-35yr age group was not significant. There were increase in WBC count among hypertensive subjects compared with normotensive subjects in all age groups. It was statistically significant at P<0.05 and <0.001 among hypertensive age groups 36-50yrs and >66yrs respectively. Neutrophil was increased in all age groups and was statistically significant at P<0.05 except 20-35yr age group. No changes were seen on lymphocytes, monocytes, eosinophils and basophils.

Conclusion: Haematological parameters investigated could predict possible cardiovascular abnormalities such as hypertension.
