Pulmonary hypertension and metabolic disorders

Abstract

This review presents current data regarding the relationship between hyperuricemia, obesity, diabetes mellitus, lipid disorders and pulmonary arterial hypertension (PAH), chronic thromboembolic pulmonary hypertension (CTEPH). Hyperuricemia is associated with a higher risk of developing of PAH, worse prognosis of PAH and greater severity of the patient's condition. Obesity leads to the development of pro-inflammatory and vasoconstrictor effects, hypoxia, which contributes to the progression of PH, however, the survival rate of patients with PH and overweight or obesity is higher than with normal or reduced body weight. Diabetes mellitus and concomitant insulin resistance are associated with a high risk of hospitalization for right ventricular heart failure and mortality. The presence of PAH is associated with lower values of total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, and probably high-density lipoprotein cholesterol (HDL-C). At the same time, higher levels of LDL-С and HDL-С in PAH and CTEPH determine a better prognosis of the disease.All metabolic disorders considered have common mechanisms of influence on PH. Further study of their pathogenetic basis will make it possible to develop unified approaches to methods of their correction in patients with various types of pulmonary hypertension.
