Background : Essential hypertension is very common worldwide & it has many harmful effects.

The aim of our study was to find whether any relation between blood groups and essential hypertension exists.

Materials and methods : 439 hypertensive patients were chosen from the hypertensive clinic in Sulaimanyia , 288 females & 151 males.

Their age ranging between 40- 76 years (mean 58).

The blood group of these patients was determined.

At the same time a control group of 439 non hypertensive persons were chosen in whom the blood groups were determined.

Results : A close relation between blood group O and hypertension where 51.2 % of hypertensive patients were group O, while 23.5 % were group A, 19.8 % were group B and 5.2 % were group AB.

This close relation between hypertension and blood group O was found almost equally in both female & in male patients.

Conclusion : Group O people in Sulaimanyia are more prone to have essential hypertension than other blood groups.
