Features of clinical and anamnestic characteristics and treatment of patients with hypertriglyceridemia (the data from Kuzbass register of dyslipidemias)

Abstract

Aim. To study the features of clinical and anamnestic characteristics and treatment of patients with hypertriglyceridemia (HTG) using the data of the lipid control center of Kemerovo.Methods. The single-center retrospective study is based on the data of patients dynamic observation (n = 100) in the Dyslipidemia Registry of Kuzbass in 2019. A comparative analysis of clinical and anamnestic characteristics, lipidogram parameters and therapy was performed at the time when the patients were included in the study and after 6–12 months in patients with HTG (the criterion was the level of triglycerides (TG) above 1.69 mmol/L) and in patients without it. Indications for consulting a lipidologist were high cholesterol (levels of total cholesterol (TC) ˃7.5 mmol/L or low-density lipoprotein cholesterol ˃4.9 mmol/L or TG˃5 mmol/L), requirement of the high dose and/or combination therapy of lipid-lowering drugs; medical history of cardiovascular diseases and/or revascularization of vascular bed in patients under 55 years of age; suspected intolerance to lipid-lowering therapy due to the developed side effects; the issue of lipid-lowering therapy in complex clinical situations.Results. Among the patients who visited a lipidologist in 2019, mixed hypertriglyceridemia was noted in 56 (56%) of cases, while 44 (44%) patients had other lipid metabolism disorders without increased levels of TG. A distinctive feature of patients with mixed hypertriglyceridemia is the lower incidence of myocardial infarctions (p = 0.029) and lower number of coronary stents (p = 0.018) in the medical history, despite the initially higher levels of TC (p = 0.005) and TG (p = 0.000). According to the results of 6–12 months observation, a significant decrease in TC (p = 0.001) and TG (p = 0.044) levels during the lipid-lowering therapy was revealed due to the addition of fenofibrate (p = 0.000) to all groups of patients who were monitored by a lipidologist.Conclusion. The patients with dyslipidemia and HTG are a complex category of patients who require combined lipid-lowering therapy, which can only be prescribed by a lipidologist.
