Dyslipidemia and its associated factors among adult cardiac patients at Ambo university referral hospital, Oromia region, west Ethiopia

Abstract

Background: Cardiovascular disease is a cluster of illnesses that affect the heart and blood vessels. Dyslipidemia is the most common risk factor for cardiovascular disease, causing more than 4 million deaths each year worldwide. However, there is very little evidence concerning the prevalence and pattern of dyslipidemia among cardiac patients in Ethiopia.

Methods: Hospital-based cross-sectional study was conducted from June to September 2022 at Ambo University referral hospital. Data on socio-demographic, clinical and anthropometric features were collected from adults with cardiac diseases using a convenient sampling technique. Lipid profiles and uric acid were measured from overnight fasting blood. The national cholesterol education program adult treatment panel (NCEP-ATP) III criteria was used to define dyslipidemia.

Results: A total of 269 participants were enrolled and the overall 76.6% [95% confidence interval (CI):72.1-81] of patients had at least one dyslipidemia. The prevalence of total cholesterol (TC) ⩾200 mg/dl, triglyceride (TG), LDL-cholesterol and HDL-cholesterol < 40 mg/dl were 38.9%, 44.6%, 29.4%, and 53.5%, respectively. Age > 54 was associated with TC and TG dyslipidemia, adjusted odds ratio (aOR) and (95% CI) were 2.6(1.4-4.8) and 2.4(1.2-4.7), respectively. While, a family history of heart disease, sedentary lifestyle and obesity were associated with TC dyslipidemia, aOR (95%CI) were 1.9(1.1-3.5), 1.4 (1.4-14.6) and 6.7 (1.4-32.5), respectively. In addition, diabetetes mellitus and abdominal obesity were significantly associated with TG dyslipidemia, aOR (95%CI) were 1.9(1.0-3.6) and 2.6(1.16-5.8), respectively. Moreover, uric acid was positively correlated with TC and TG level.

Conclusions: The results indicate that more than 75% of the cardiac patients had at least one dyslipidemia. This reflects the need for regular monitoring of lipid profiles and intensive counseling in this population to mitigate further cardio-metabolic complications.
