  • Title: [Coronary artery spasms].
    Author: Bertrand ME, Laisné C, Lefebvre JM, Carré A, Warembourg H, Lekieffre J.
    Journal: Arch Mal Coeur Vaiss; 1977 Dec; 70(12):1233-44. PubMed ID: 415675.
    Abstract:
    In a series of 2000 coronary arteriographies, spasm of the coronary artery was found in 52 cases, which were divided into three groups: 41 cases of "iatrogenic" spasm caused by stimulating the ostium of the coronary artery (usually the right) with the tip of the catheter; 8 cases of spasm on top of an organic fixed lesion; 4 cases of coronary spasm on a coronary artery which was reported as "radiologically normal". The study includes a review of the circumstances which favour or impede discovery of coronary spasm, as well as a provocation test using methyl ergometrine. This test seems to be specific in that it only produced coronary spasm in patients with Prinzmetal's syndrome, and excluded the cases of angina with normal coronary arteriography. The patients with spasm on top of a fixed organic lesion underwent a successful aorto-coronary bypass graft together with resection of the pre- and sub-aortic nerve plexus. Patients with a spasm in an artery which was "arteriographically normal" were treated medically by nitrate compounds and vaso-dilators. Three of these patients had an excellent result with medical treatment. Treatment failed in the fourth patient, who then obtained benefit from straight-forward resection of the pre- and sub-aortic nerve plexus with an excellent result which has been maintained for over six months.
