Cocaine can cause coronary artery spasms which may lead to a myocardial infarction. This effect can happen randomly to any user. The coronary artery spasms can occur on the user's first usage or any other usage after. The coronary spasms cause the ectopic ventricular foci of the heart to become hypoxic and the extreme irritability can trigger life-threatening ventricular arrhythmias.
