Patterns of Dyslipidemia in the Anemic and Nonanemic Hypertensive Saudi Population: A Cross-Sectional Study

Abstract

Background: Risk factors of cardiovascular disease include dyslipidemia, hypertension (HTN), and anemia. Our objective is to assess the patterns of dyslipidemia in the anemic and non-anemic hypertensive Saudi population. Methods: A retrospective, cross-sectional study of the gender, blood pressure, lipid markers, and CBC parameters of 3111 subjects, which were retrieved from the database of Al-Borg Medical Laboratories over a six-year period (2014–2019), was carried out. Means were compared among study groups and the prevalence, association, and diagnostic accuracy of lipid markers for HTN were evaluated. Results: TG, LDL/HDL, and TG/HDL were significantly higher (P < 0.0001) in hypertensives. Anemia reduces TC and LDL (P < 0.0001) in both genders, and reduces all markers and increases HDL (P < 0.01) in male hypertensives. HTN was more prevalent in anemics with high TC than normal TC (38.23% vs 11.17%, P < 0.001) and in non-anemics with high TG than normal TG (56.31% vs 21.22%, P < 0.001). Furthermore, non-anemics with high TG/HDL had the highest risk for HTN (RR = 1.20, 95% CI = 1.1551– 1.2473, P < 0.0001). Elevated TC (P = 0.0142), TG (P < 0.0001), TC/HDL (P < 0.0001), LDL/HDL (P < 0.0001), and TG/HDL (P < 0.0001), and low HDL (P < 0.0001) were risk factors for HTN as shown by ORs. In anemics, high TC/HDL, LDL/HDL, and TG/HDL were not. Importantly, only TG and TG/HDL had a discriminating capacity for HTN. Conclusion: The anemic state of hypertensive Saudi patients influences dyslipidemia which warrants further investigation.
