Abstract

Introduction: Hypertension remains the major preventable cause of cardiovascular disease (CVD). Lipoprotein (a) is seen to be associated with established essential hypertension and contributes to atherogenesis or to thrombogenesis or both.

Aim: Correlation between lipoprotein (a) [Lp(a)] and lipid abnormalities in patients with newly detected hypertension and its association with severity of hypertension.

Methods: It was a cross-sectional observational study carried out at PGIMER, DR. RML Hospital, New Delhi, India. Estimation of serum Lp (a) and lipid parameters along with routine laboratory investigations were carried out in 100 newly diagnosed cases with hypertension and compared with age and sex matched 50 healthy normotensive controls.

Result: Amongst 100 cases the mean systolic and diastolic blood pressure was 160.68 ± 19.75 mmHg and 84.44 ± 4.32 mmHg respectively. The mean serum Lp (a) in cases was 34.03 ± 7.55 mg/dl as compared to 24.13 ± 4.41 mg/dl in controls (p < 0.0001). 62% of cases as compared to 12% of controls had elevated serum Lp (a) levels. Apart from that, the levels of Lp (a) and lipid parameters increased significantly with higher stage of disease (p < 0.0001). Approximately 8% of cases had left ventricular hypertrophy as compared to 1% of control. Similarly, 18% of cases had Non-alcoholic fatty liver disease as compared to 4% of controls. 5% of cases had retinopathy as compared to nil in controls. 4% of cases had microalbuminuria as compared to nil in controls.

Conclusion: It was observed that newly detected hypertension is associated with major derangements of Lp (a) and lipid parameters. We also concluded that end organ involvement is significantly higher in newly detected hypertensives as compared to normotensive subjects and it was attributed to be due to lipid abnormalities observed in the group.

Keywords: Grading of hypertension; lipid profile; lipoprotein (a); newly detected hypertension.
