BACKGROUND: It remains unclear how closely the small dense low-density lipoprotein (LDL) (diameter < or =25.5 nm) is associated with various types of coronary heart disease (CHD) in Japanese patients, an ethnic group with lower serum cholesterol levels and less massive obesity compared with Western populations. METHODS AND RESULTS: We measured mean LDL particle diameter by gradient gel electrophoresis in 571 patients with CHD and in 263 healthy subjects who served as control patients. Patients with CHD were classified into acute coronary syndrome (ACS), stable CHD and vasospastic angina. High-density lipoprotein cholesterol and apolipoprotein-A1 and -B were significantly different between patients with CHD and controls. LDL size in patients with CHD was markedly smaller than that in controls in both men and women (25.5 +/- 0.7 vs 25.9 +/- 0.4 and 25.7 +/- 0.7 vs 26.0 +/- 0.5 nm, respectively). LDL cholesterol was significantly higher in patients with ACS than in other groups. Plasma levels of high-density lipoprotein cholesterol decreased as the number of diseased vessels or angiographic coronary severity evaluated by Gensini score increased, but the LDL size was comparable irrespective of the type of CHD and the extent and severity of the lesions. Multiple logistic regression analysis revealed that small dense LDL was independently associated with the incidence of CHD in both sexes (odds ratio [OR] 3.5, 95% CI 2.1-5.7, and OR 2.9, 95% CI 1.5-5.6, P <.005). CONCLUSION: Our study suggests that the small dense LDL is strongly associated with various types of CHD, independent of traditional and nontraditional coronary risk factors, but is not related to the severity and extent of the coronary lesions. |
