Pharmacological Control of Heart and Circulation, Volume 1, documents the proceedings of the 3rd Congress of the Hungarian Pharmacological Society held in Budapest, 1979. Because the papers published in this volume cover diverse areas of the cardiovascular field, they had to be arranged into several smaller symposia. The common thread running through these symposia is their focus on some pathological condition of the heart and circulation as well as on their control by drugs. The first symposium is devoted to the pharmacological control of the adverse effects of coronary insufficiency including disturbances in rhythm. The second symposium is dedicated to cardiac hypertrophy; to the action of cardiac hypertrophy on the sensitivity of the heart to drugs; and to the changes in the biochemical parameters of the myocardium due to cardiomegaly. The third symposium deals with hypertension and its pharmacological control. Two separate symposia are devoted to new drugs, namely the fourth symposium to the cerebrovascular activity of Cavinton—a synthetic Vinca-derivative; and the fifth to a newly developed beta-adrenergic blocking agent, Tobanum, to its anti-arrhythmic action, its effect in myocardial ischemia and in hypertension. Finally, a short symposium on serotonin and serotonin antagonists, both of great importance in cardiovascular pharmacology, is included.
