Correlation between small and dense low-density lipoprotein cholesterol and cardiovascular events in Beijing community population

The relationship between small dense low-density lipoprotein cholesterol (sdLDL-C) and different cardiovascular events has been observed in several large community studies, and the results have been controversial. However, there is currently no cross-sectional or longitudinal follow-up study on sdLDL-C in the Chinese hypertension population. We analyzed the association of plasma sdLDL-C levels with major adverse cardiovascular events in 1325 subjects from a longitudinal follow-up community-based population in Beijing, China. During the follow-up period, a total of 191 subjects had MACEs. Cox regression analysis showed that sdLDL-C is a major risk factor for MACEs independent of sex, age, BMI, hypertension, diabetes, smoking, SBP, DBP, FBG, eGFR in the general community population (1.013 (1.001 -1.025, P < .05)), but the correlation disappeared after adjusting for TC and HDL-C in Model 3. Cox analysis showed that hypertension combined with high level of sdLDL-C was still the risk factor for MACEs ((2.079 (1.039-4.148)). Our findings in the Chinese cohort support that sdLDL-C is a risk factor for major adverse cardiovascular events in hypertension subjects.
