Are heart spasms serious?

What does the ECG show in prinzmetal angina?
Electrocardiography is the key to diagnosing vasospastic angina. ECG changes demonstrate transient ST-segment elevation during episodes of chest pain, which elevation resolves when the pain settles. ST-segment elevation represents transmural myocardial ischemia and is accompanied by reciprocal ST depressions.
Which drug is most likely to accentuate variant prinzmetal angina?
Multiple triggers have been associated with the development of vasospastic angina. Several drugs such as ephedrine and sumatriptan can cause typical chest pain due to coronary spasm. Recreational drugs like cocaine, amphetamines, alcohol, and marijuana are also possible precipitating factors.
