A strong positive and continuous correlation exists between systolic blood pressure (SBP), diastolic blood pressure (DBP), and the risk of cardiovascular tablet and renal diseases. However, this risk appears to be higher for SBP than DBP. Despite the advances in understanding the pathophysiology of hypertension and the benefits of pharmacologic therapy in reducing this risk, satisfactory blood pressure (BP) control is only achieved in a small fraction of the hypertensive population. Various studies outside Nigeria have shown a better control of DBP, compared to SBP, in hypertensives receiving treatment. An earlier study in a tertiary health institution in Nigeria found that overall blood pressure control was 25.4%, but the study did not address the differential control of systolic and diastolic blood pressures.
Taking into consideration the importance of hypertension as a very strong risk factor for stroke, chronic renal failure (CRF), and heart failure in Nigeria, we set out to evaluate the pattern of SBP and DBP control in treated essential hypertensives attending a secondary health center in southwest Nigeria. The opportunity to define the relationship between SBP and DBP control among hypertensives in this centre has a possible implication on early prevention of cardiovascular events. canadian discount drugs
