Serum lipids profile of untreated hypertensive patients in Port Harcourt, Nigeria

ABSTRACT

Background: Hypertension is the commonest non-communicable disease with variable prevalence rates in different parts of the world. Dyslipidaemia is associated with and predisposes to hypertension and hence increases the risk of cardiovascular disease. Aim: To determine the lipid profile in newly diagnosed hypertensive patients and compare them with age, sex and body mass index (BMI) of matched healthy non-hypertensive controls. Methods: A prospective descriptive study of newly diagnosed and treatment naive hypertensive patients. Healthy non-hypertensive adult Nigerians, who gave informed consent, consisting mainly of hospital staff and relatives of patients, matched for sex, age and BMI were recruited as controls. Results: A total of 89 patients, 42 females and 47 males and 87 healthy adults matched for age, sex, and body size were recruited as controls. Mean age of hypertensive subjects was 42.6±9.3 years and mean age for the control subjects was 41.5±4.5 years. The mean systolic blood pressure in the hypertensive subjects was 177.6±20.1 mmHg and mean diastolic blood pressure was 110.9 ±9.9 mmHg. The mean BMI in the hypertensive patients was 28.7±4.2 kg/m2, while the controls had mean BMI of 28.2±4.0 kg/m2 (P=0.5178). The mean total cholesterol (TCH) was 5.3±1.1 mmol/l in the study subjects and 4.7±0.95 mmol/l in the controls (P =0.0002). The mean low density lipoprotein cholesterol 250 in the study subjects was 4.3±1.1 mmol/l and 3.6±0.9 mmol/l in the control group (P=0.000054), while the mean triglyceride in the subjects was 1.3±0.3 mmol/l and 1.0±0.3 mmol/l in the controls (P=0.0000). Conclusion: Newly diagnosed hypertensives have significantly higher serum cholesterol levels than non-hypertensives of comparable age, sex and body size
