The Correct Answer is B

Prinzmetal angina
  • Substernal chest pain occurring at rest
  • Due to vasospasm with or without a fixed atherosclerotic lesion
  • Pathogenesis is unknown
  • Treated with calcium channel blockers resulting in vasodilatation
It may be accompanied by palpitations or severe shortness of breath, explosive in onset, severe, and frightening. It may also be brought on by effort, although the workload at which it is precipitated usually varies considerably. Variant angina is caused by focal spasm of proximal epicardial coronary arteries; in approximately three-fourths of the patients atherosclerotic coronary artery obstruction is present, in which case the vasospasm occurs near the stenotic lesion.
