• Calcium channel blockers (CCBs) are the first-line treatment for coronary artery spasm (CAS).
• The non-specific arterial dilator CCBs form the cornerstone of treatment for the long-term prevention of CAS.
• Both dihydropyridine (DHP) and non-DHP drugs can be used.
• The efficacy of these drugs in preventing CAS, and therefore abolishing, or consistently decreasing, angina attacks, has been clearly demonstrated in several studies and is a common experience in clinical practice.
• Because most episodes of CAS-induced myocardial ischaemia are silent, treatment should ideally aim to abolish not only angina episodes, but also episodes of silent myocardial ischaemia detected by 24/48-h ECG Holter monitoring.
