Mild cardiovascular spasm can be cured. Recurrent cardiovascular spasm with complications such as arrhythmia and heart failure is difficult to cure. Cardiovascular spasm, or coronary spasm, refers to transient contraction of the coronary arteries caused by various reasons, resulting in complete or incomplete occlusion of the coronary arteries and ischemic infarction of the heart muscle cells. Mild cardiovascular spasm can be rapidly relieved by sublingual nitroglycerin or taking quick-acting heart pills and treated with non-dihydropyridine calcium channel blockers such as verapamil and diltiazem, which are generally curable. Hereditary coronary artery spasm is generally not curable due to its complex etiology and recurrent episodes accompanied by arrhythmias, heart failure and other complications, for which there is no treatment for the etiology. It is recommended that patients actively seek medical advice and use medication under the guidance of a physician.
