INTRODUCTION: The present investigation aimed to evaluate the influence of serum triglycerides (TG) on other plasma lipids in male patients less than 65 years of age intended for hypolipidaemic treatment.
METHODS: Lipid profiles of a cohort of 412 dyslipidaemic male patients aged 53.4 +/- 7.7 years (mean +/- standard deviation) were evaluated. Patients were stratified in accordance with their fasting plasma lipid levels. They were divided into multiple groups on the basis of serum TG (> or = 150 or < 150 mg/dl) and high-density lipoprotein cholesterol (HDL-C > or = 40 or < 40 mg/dl).
RESULTS: Patients with TG > or = 150 mg/dl had higher total cholesterol and lower HDL-C levels compared with those with TG < 150 mg/dl (p = 0.005 and p < 0.001, respectively). Patients with HDL-C < 40 mg/dl had similar total cholesterol levels and higher TG levels compared to those with HDL-C > or = 40 mg/dl (p < 0.001). In all patients, an inverse correlation between TG and HDL-C was found (r = -0.286, p < 0.001). Additionally, HDL-C levels were inversely correlated with the TG concentration in patients with TG < 150 mg/dl (r = -0.135, p = 0.042) and TG > or = 150 mg/dl (r = -0.188, p = 0.002).
CONCLUSIONS: An inverse correlation between TG and HDL-C levels seems to exist in the sampled population, revealing a close link between the metabolic pathways for TG and HDL-C. This inverse correlation appears to persist even in patients with low fasting TG levels.
