[Comparative analysis of the levels of anti-prostaglandin F2 alpha antibodies in the normal state and in cardiovascular diseases].

The ELISA test was performed on sera of normal donors and patients with myocardial infarction (MI) and essential hypertension (EH) to detect autoantibodies against prostaglandin F2 alpha (a-PGF2 alpha). The a-PGF2 alpha level was much higher after immune complexes dissociation. Baseline a-PGF2 alpha was elevated in EH patients with a sudden rise in blood pressure, and in MI patients without hypertension and unstable angina. MI patients with bradyarrhythmias also had elevated a-PGF2 alpha levels. Baseline a-PGF2 alpha was rather low in the sera of donors, chronic EH patients with hypertension and unstable angina, suggesting that a-PGF2 alpha has a physiological role to play.
