Why the study?
Does the presence of congestive heart failure affect the incidence of acute myocardial infarction and mortality in patients presenting with severe chest pain?
Does the presence of congestive heart failure affect the incidence of acute myocardial infarction and mortality in patients presenting with severe chest pain?
Patients with severe chest pain and congestive heart failure have a markedly lower incidence of subsequent acute myocardial infarction compared to those without heart failure, suggesting poor mechanical performance may protect against acute infarction.
No takes yet. Share an insight, caveat, or question.
CHF with severe chest pain was associated with lower MI rates; hypothesis-generating and should not change practice pending prospective confirmation.
Hjalmarson et al. (1976) studied this question.
