Prognosis Of Acute Myocardial Infarction Complicated By Complete Heart Block (The Worcester Heart Attack Study), Robert Goldberg, Juan Zevallos, Jorge Yarzebski, Joseph Alpert, Joel Gore, Z. Chen, James Dalen

Jorge L. Yarzebski

As part of a community-based study of patients hospitalized with acute myocardial infarction (AMI) in the Worcester, Massachusetts, metropolitan area, changes over time in the incidence rates of complete heart block (CHB) complicating AMI, and the prognostic impact of CHB on the in-hospital and long-term survival of these patients were examined. In all, 4,762 patients with validated AMI hospitalized at 16 hospitals in the Worcester metropolitan area during 1975, 1978, 1981, 1984, 1986 and 1988 constituted the study sample. The incidence rates of CHB complicating AMI remained relatively stable at 5.8% over the 13-year (1975 to 1988) period studied. The …

The peripheral white blood cell count on presentation with acute myocardial infarction directly correlates with short-term in-hospital mortality. This association is independent of other prognostic factors, including extent and size of the acute myocardial infarction.
