Abstract

BACKGROUND:

The blood concentrations of total cholesterol and low-density lipoprotein (LDL) do not predict survival in patients older than 60 years. The atherogenic index of plasma (AIP) is a logarithm of the triacylglycerol to high-density lipoprotein (HDL) ratio and a surrogate for the concentration of small dense LDL. It might be a better reflection of the risk of all-cause death in elderly patients.

METHODS:

We conducted a prospective observational study of patients with arterial hypertension older than 60 years. The concentrations of total cholesterol, LDL, HDL and triacylglycerol were measured at the time of the recruitment and the patients were observed for 10 years. Cox regression analysis was performed to assess the effects of lipoproteins and AIP on survival.

RESULTS:

A total of 500 patients were recruited and 473 of them (226 men, 247 women) either died or successfully completed the 10-year follow-up and were included in the analysis. The AIP was positively associated, while HDL concentration was negatively associated with the risk of all-cause death adjusted for age, smoking habits, statin use, history of diabetes mellitus, myocardial infarction, stroke and peripheral artery occlusive disease (PAOD) in elderly women but not in men. The LDL, total cholesterol, triacylglycerol and non-HDL concentrations were not associated with the risk of death in both sexes.

CONCLUSIONS:

The AIP is positively associated with the risk of all-cause death in elderly women with arterial hypertension independent of age, smoking habits, statin therapy and comorbidities.
