The relationship between apolipoprotein E (Apo E) phenotypes and progression of coronary atherosclerosis was investigated in 125 patients with coronary artery disease (CAD) proven angiographically (101 males, 24 females).
A high-resolution method was used to study the allele frequencies of a hypervariable minisatellite region close to the apolipoprotein B gene in 110 patients with severe coronary disease and in 117 normal controls.
Genetic variation in the cholesteryl ester transfer protein and apolipoprotein A-I genes and its relation to coronary heart disease in a Sri Lankan population.
Although no definite evidence is available showing that tissue plasminogen activator antigen is a risk factor for coronary heart disease, the present study suggests a positive ecologic association between this hemostatic factor and coronary heart disease mortality.
The value of lipoprotein (a) [Lp(a)] in the prediction of coronary artery disease risk very early in life remains to be established in different racial groups.
Lipoprotein (a) (Lp(a)) is a low density lipoprotein-like particle which contains the plasminogen-like apolipoprotein a. Lp(a) levels are elevated in patients with atherosclerotic coronary artery disease.
Intermediate-density lipoproteins (IDLs) and lipoprotein (a) are highly atherogenic species that each normally account for up to 10% to 15% total LDL cholesterol but may be disproportionately elevated in pathologic states and may therefore contribute disproportionately to coronary disease risk in certain patients.
To elucidate the association of thermolabile MTHFR with the development of coronary artery disease, we determined the thermostability of lymphocyte MTHFR in 212 patients with proven coronary artery disease and in 202 controls without clinical evidence of atherosclerotic vascular disease.
To determine the influence of the apolipoprotein E polymorphism on the occurrence of coronary artery disease (CAD) and on serum lipids, lipoproteins and apolipoproteins we studied 145 patients with angiographically defined CAD and compared them with 153 control subjects without history or complaints of vascular disease and with 35 subjects without significant stenosis on coronary arteriography.
Three polymorphic sites of the apolipoprotein B gene - the insertion/deletion signal peptide, XbaI and EcoRI sites - were examined in a sample of 107 healthy men and in 46 men with evidence of coronary heart disease selected from a large population survey of South Asians aged 40-69 in London, U.K.
Patients with two abnormal LDL receptor genes (homozygous deficient patients) have severe hypercholesterolemia and life-threatening coronary artery disease in childhood.
This result suggests the possibility that genetic variation at the LDL receptor locus or a closely linked locus on chromosome 19 may be responsible for metabolic alterations in ALP pattern B that account for a substantial proportion of the familial predisposition to coronary artery disease in the general population.
Apolipoprotein(a) phenotypes, Lp(a) concentration and plasma lipid levels in relation to coronary heart disease in a Chinese population: evidence for the role of the apo(a) gene in coronary heart disease.
Plasma levels of two lipoprotein risk factors, high-density lipoprotein-cholesterol (HDL-C) and apolipoprotein A-1 (apo A-1), have been shown to be negatively associated with the risk of developing coronary artery disease, and several reports have examined familial factors in HDL-C and apo A-1 levels.
The ACE/ID polymorphism seems to be a potent risk factor of coronary heart disease in subjects formerly considered to be at low risk according to common criteria.
Apolipoprotein(a) phenotypes, Lp(a) concentration and plasma lipid levels in relation to coronary heart disease in a Chinese population: evidence for the role of the apo(a) gene in coronary heart disease.
Patterns of RFLP association were studied, to identify gene regions influencing quantitative variation in lipid and lipoprotein traits (coronary artery disease [CAD] risk factors or metabolically related traits).
In a sample of both 83 healthy individuals and 105 young patients with coronary artery disease from Sweden, the frequency of the 4G allele is roughly 0.5, and those individuals homozygous for the 4G allele have higher levels of PAI-1 than those with other genotypes (29% higher).
