meaning of Artery spasm, coronary

Artery spasm, coronary meaning in Medical Dictionary

a rapid constriction of a coronary artery that deprives one's heart muscle mass of blood and air. This will probably trigger a kind of unexpected chest discomfort called variant angina or Prinzmetal angina. Coronary artery spasm can be triggered by mental tension, medications, street medicines (very cocaine), and contact with extreme cool. Treatments range from the usage of beta-blocker medicines and, classically, nitroglycerin to allow the coronary arteries to start.
