Prevention with molsidomine of coronary artery spasm caused by alkalosis

American Heart Journal
S WeberM Degeorges


A provocative test of coronary artery spasm caused by alkalosis was used to evaluate a possible anti-coronary artery spasm effect of molsidomine. The rapid infusion of an alkaline buffer followed by maximal voluntary hyperventilation in 10 patients with angina at rest led to the appearance of anginal pain and significant, transient ischemic changes of the ST segment resulting from alkalosis-induced coronary spasm. A second provocative test was performed under the same conditions, 24 hours later, after the administration of 4 mg of molsidomine. Molsidomine prevented the development of coronary artery spasm in 8 of the 10 patients in the study group. These preliminary results justify further clinical evaluation of molsidomine in the treatment of vasospastic angina.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
