Lipoprotein(a) and oxygen free radicals in survivors of acute myocardial infarction: effects of captopril.

Long-term treatment of survivors of an acute myocardial infarction with angiotensin-converting enzyme inhibitors has a beneficial impact on their long-term outcome. We tested the hypothesis that captopril could reductively cleave the lipoprotein(a) molecule and in addition act as a scavenger of oxygen free radicals. In a double-blind trial, 20 patients were randomized to receive either captopril 50 mg daily or corresponding placebo. patients were followed for a period of 30 days. Blood samples were drawn prior to randomization and after 30 days of treatment. Plasma concentrations of lipoprotein(a) and malondialdehyde were evaluated. Captopril treatment produced a significant reduction in plasma content of lipoprotein(a) ( < 0.05) and at day 30 the plasma content of lipoprotein(a) was also significantly lower than that in the placebo group (p < 0.05). furthermore, on day 30 plasma concentrations of malondialdehyde, an indicator of oxidative damage, were significantly lower in the captopril group when compared to baseline values and corresponding placebo group values (p < 0.05). The observed effect of captopril treatment on lipoprotein(a) and malondialdehyde might be ascribed to the sulfhydryl group in the captopril molecule.

Polymorphism in 5' flanking region of human insulin gene. Relationships with atherosclerosis, lipid levels, and age in three samples from Denmark.

Variations in the DNA sequence flanking the 5' region of the human insulin gene (U- and L-alleles) were studied in relation to atherosclerosis, lipid levels, and age in three groups of atherosclerotic individuals and in nonatherosclerotic controls. The atherosclerotic groups comprised a postmyocardial infarction group with a mean age of 48 years, a group of individuals operated on for carotid stenosis with a mean age of 62 years, and a group of 85-year-olds with clinical coronary disease, peripheral arterial disease, or both. All 331 individuals were unrelated Caucasians of Danish ancestry. There were no significant differences (p greater than 0.05) in genotype distribution or allele frequencies between atherosclerotic and nonatherosclerotic individuals, but in the 85-year-olds, there was evidence (p less than 0.10) for a lower U-allele frequency in nonatherosclerotic women compared to atherosclerotic women. In nonatherosclerotic women, there was a significant decrease in U-allele frequency with age (60 to 85 years). This decrease does not prove conclusively, but is compatible with, the hypothesis that the U-allele predisposes to, or the L-allele protects against, atherosclerosis. The possible effect of the U-allele on the development of atherosclerosis does not seem to be mediated through conventional risk factors.
