Lipoprotein analyses in patients with stable angina and acute coronary syndrome.Int J Cardiol. 1996 Dec 06; 57(2):161-6.IJ
We have performed lipid analyses by using a table-top ultracentrifuge based on the Hatch and Lees' method in 77 subjects (60 men, 17 women: mean age, 63 years) to clarify lipoprotein disorders in coronary artery disease. Sixty-four subjects had coronary artery disease and 13 normal subjects were controls. They were divided into the groups with stable angina pectoris and with unstable angina pectoris or acute myocardial infarction (acute coronary syndromes). In patients with coronary artery disease, there were no significant differences from control in age, body mass index, total cholesterol, however, HDL cholesterol was significantly lower than those in the controls. LDL cholesterol:LDL apoB ratio, which is thought to reflect the size of LDL in coronary artery disease, was significantly smaller than that in the controls; mean values were 1.2 in coronary artery disease and 1.4 in controls. There were no significant differences in those lipoprotein disorders between the patients with stable angina and those with acute coronary syndromes. Though these lipoprotein abnormalities would not play a trigger role in acute coronary syndrome, they are characteristic of the lipid profile of patients with coronary artery disease.
