Effect of PUFA on patients with hypertension: A hospital based study

IntroductionHypertension affects more than a quarter of the global adult population. Studies conducted worldwide suggest an overall small, yet useful, role of omega-3 PUFAs in reducing blood pressure in hypertensive patients. However there is no substantial data in this regard from population based in Middle East and Asia.ObjectivesTo determine the effects of (omega-3) PUFA supplementation on the blood pressure of hypertensive patient.To identify if male and female hypertensive patients respond differently to PUFA.To identify if response of hypertensive patients to PUFA varies with the duration of hypertension and co-existence of diabetes/dyslipidemia.Materials and methodsThis observational study was conducted among hypertensive patients visiting OPD of the Gulf Medical College Hospital, Ajman, UAE, during the period Jan–Dec 2012. A total of 100 hypertensive patients on treatment with their antihypertensive medications, 50 of whom were taking n-3 PUFA supplementation, were followed up for a period of 3 months. Comparisons were drawn between the BP recordings at the time of enrollment in the study and their follow up values 3 months after enrollment.ResultsThere was a statistically significant reduction in both the systolic and diastolic blood pressures after 3 months of PUFA therapy. The BP lowering effect of PUFA was more in males. A statistically significant reduction in BP was noted in non-diabetic patients and patients with long standing hypertension.ConclusionFindings of the study suggest that omega-3 PUFA dietary supplements augment the benefits of pharmacotherapy in hypertension.
