title: [Cardiovascular effects of prostaglandin F 2 alpha in early pregnancy].
abstract: In 10 normotensive healthy early pregnant women cardiovascular studies were done before, during and after the intravenous administration of prostaglandin F2alpha with the method of quantitative sphygmometry. Arterial blood pressure was measured graphically with an automatic sphygmomanometer unit. Velocity of aortic pulse wave was determined directly on the principle of exact electronic timing. Prostaglandin F2alpha was infused with electric pump in the dosage of 6, 5, 13 and 26 mug per minute for 30 minutes in each case. Arterial blood pressure is nearly constant. Heart rate, the elasticity coefficient of the arteries E' and total peripheral resistance decreases significantly. Stroke volume, cardiac output, work and power of the heart increases significantly. Nevertheless there are no contra-indications on the part of cardiovascular system for using prostaglandin F2alpha for induction of abortion
