    Abstract:
    An early pericardial friction rub was noted in 23.4% of a population of 1264 consecutive patients admitted with acute myocardial infarction. The incidence of the rub did not vary with age, sex or past cardiac history. The pericardial rub, however, was more often a complication of Q- than non-Q-wave infarcts (25.5% vs 10.5%, P greater than 0.001) and of anterior than inferior infarcts (35.3% vs 20.8%, P greater than 0.001). In comparing the 297 patients with a pericardial rub to the 967 others, we noted that the former group had a higher CK peak (1706 +/- 1110 UI l-1 vs 1189 +/- 1038 UI l-1, P greater than 0.001) and a higher incidence of Killip class greater than 1 (47.5% vs 33.2%, P greater than 0.001), atrial flutter or fibrillation (22.2% vs 9.3%, P greater than 0.001), second or third degree atrioventricular blocks (16.8% vs 9.4%, P greater than 0.001) and complete bundle branch block (14.5% vs 7.1%, P greater than 0.001). In spite of this, the development of a pericardial rub did not increase the in-hospital mortality (10.8% in patients with pericardial rub; 11.3% in those without).
