  • Title: Coronary embolism in valvular heart disease.
    Author: Charles RG, Epstein EJ, Holt S, Coulshed N.
    Journal: Q J Med; 1982; 51(202):147-61. PubMed ID: 7111677.
    Abstract:
    Coronary embolism is considered to be rare but recent evidence suggests that it may be underdiagnosed, and implicated in acute myocardial infarction associated with angiographically normal coronary arteries. Twenty-six patients were studied. In six, coronary embolism was a primary cause of death confirmed at autopsy. In 20 patients, 23 episodes of coronary embolism were diagnosed clinically. The left coronary system was occluded in 65 per cent, transient electrocardiographic changes occurred in 30 per cent, and either no history or an atypical history of acute myocardial infarction occurred in 29 per cent. Other systemic emboli occurred in 25 per cent. Aortic valve lesions were present in 70 per cent and combined mitral and aortic valve disease in 55 per cent of the patients. The incidence of coronary risk factors was low. Sequelae included increased dyspnoea (35 per cent), ventricular aneurysm (25 per cent) and cardiac failure (12 per cent). Angina rarely followed acute myocardial infarction.
