Prevalence, clinical features, and acute course of atypical myocardial infarction.
Ninety-four consecutive patients (60 men and 34 women; mean age 68.5+-11.5 years) with acute myocardial infarction (MI) were investigated retrospectively, in order to evaluate the prevalence, clinical features, and shortterm course of the atypical forms (symptoms other than chest pain).
An atypical MI was found in 30 patients, with a prevalence of 32% (95% confidence limits 27-36%). It was most prevalent in women above sixty-five years old (P<0.05).
Abdominal pain, paroxysmal dyspnea, and pulmonary edema were the most frequent symptoms (33%, 17%, 13%, respectively).
No differences were observed between typical and atypical MI in regard to risk factors (hypercholesterolemia, arterial hypertension, diabetes mellitus, cigarette smoking) and history of MI, cerebrovascular disease, peripheral vascular disease, or chronic lung disease.
