The visceral adiposity index, lipid accumulation product, and plasma atherogenic index are associated with subclinical atherosclerosis in patients with newly diagnosed acromegaly.

BACKGROUND

Acromegaly is a rare chronic endocrine disorder, the active form of which is associated with an increased risk of cardiovascular and metabolic disease. Therefore, early diagnosis and treatment of cardiovascular diseases in acromegaly patients are important in terms of morbidity and mortality. The aim of this study was to determine whether the visceral adiposity index (VAI), lipid accumulation product (LAP), and plasma atherogenic index (PAI) are early cardiovascular risk markers in patients with active acromegaly.

METHODS

The study included 45 patients newly diagnosed with acromegaly and 45 age-sex matched healthy control subjects. The VAI, LAP, and PAI values were calculated, and carotid artery intima media thickness (CIMT) was measured in both the patients and control groups.

RESULTS

The PAI, VAI, LAP, and CIMT values were significantly higher in patients with acromegaly compared with the control subjects (p < 0.004, p < 0.027, p <0.012, and p <0.001, respectively). In the patient group, a significant positive correlation was found between the growth hormone (GH) and insulin-like growth factor I (IGF-I) levels, and between the VAI, LAP and PAI values. A significant positive correlation was determined between CIMT and LAP values in the patient group.

DISCUSSION: CIMT is a noninvasive method used to show early atherosclerosis. However, it is operator dependent. Therefore, VAI, LAP and PAI can be used as noninvasive, simple measurement methods to evaluate early atherosclerosis in patients with acromegaly.
