Remnant-like particle cholesterol is a major risk factor for myocardial infarction in vasospastic angina with nearly normal coronary artery.
We investigated the association of remnant-like particle cholesterol (RLP-C), with vasospastic angina (VSA). We selected 66 subjects with nearly normal coronary artery as a control group, and 74 VSA with nearly normal coronary artery, of whom 19 had prior myocardial infarction (MI). Coronary risk factors, triglyceride, lipoproteins and apolipoproteins were evaluated using stepwise discriminant analysis, smoking was the only discriminator of the control group from VSA and RLP-C was the only discriminator of VSA with MI from VSA without MI. In comparison between VSA with and without MI, using stepwise logistic regression analysis, the only significant variable was RLP-C, and odds ratio of RLP-C for MI was 1.59. Thus, RLP-C is a major discriminator of VSA with MI and appears to be a major risk factor for MI in VSA.
