Arteriographic demonstration of coronary artery spasm during thrombolysis

Abstract

A 60-year-old man with an acute inferior-wall myocardial infarction was noted, on arteriography, to have an occluded distal right coronary artery. The vessel was reopened with intravenous tissue plasminogen activator; during resolution of the clot, spasm was observed arteriographically but was successfully treated with intracoronary nitroglycerin. Follow-up arteriography showed a normal right coronary artery. The significance of this case lies in the fact that we were able to document the occurrence of spasm during coronary thrombolysis; such documentation supports the hypothesis that spasm may be a factor in the initiation of coronary thrombosis.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
