[Comparative evaluation of prostaglandins E1 and E2 in patients with hypertension]

Changes in ABP, ECG, cerebral and peripheral hemodynamics were examined in 29 patients with second-stage essential hypertension before and within 1 or 2 days after PGE1 and PGE2 infusions administered during follow-up or in the presence of a hypotensive therapy. PGE were shown to be active vasodilators increasing cerebral and peripheral circulation. Vascular PG effects persisted for 1 or 2 days after the administration. Hypertensive patients demonstrated two patterns of hemodynamic response to PGE. The patients with higher total peripheral resistance (TPR) and low stroke and cardiac indices (SI and CI) during follow-up or hypotensive treatment were more sensitive to PGE, their ABP falling because of declining TPR. The patients with high SI and normal or slightly elevated TPR were less sensitive to PGE, their ABP falling mostly at the expense of declining SI. Most patients showed changed end portion of the ventricular complex immediately after PGE administration that vanished within one or two days. In coronary patients, angina of effort occurred less frequently after PGE infusion.
