[Cardiovascular effect of 15(S)-15-methyl-prostaglandin F2alpha].
The reaction of the cardiovascular system on one intramuscular injection of 250 microgram 15-methyl-prostaglandin F2alpha was examined in 14 normotensive healthy pregnant women between 7th and 11th weeks of gestation with the method of quantitative sphygmometry with unbloody graphic recording of arterial blood pressure and direct electronic determination of velocity of aortic pulse wave. The tests were done in 10 patients in intervals of 5 minutes for one hour and in 4 subjects for 12 hours in intervals of one hour. Systolic blood pressure remains nearly constant, but diastolic blood pressure increases and then decreases significantly. Heart rate decreases significantly. Aortic pulse wave velocity decreases in a characteristic manner. Analogous to the biphasic behaviour of blood pressure cardiac output decreases significantly, but then increases insignificantly. The inverse changes of total peripheral resistance are insignificant. Comparing these reactions with the cardiovascular effects of prostaglandin F2alpha or E2, 15-methyl-prostaglandin F2alpha shows the smallest circulatory alterations.
