This study was undertaken to determine whether patients with silent ischemia (SI) (a positive thallium stress test without chest pain) have nonchest-pain symptoms that might serve as "anginal equivalents." Two hundred ninety-four individuals on completing a stress test were requested to score ten symptoms on a questionnaire (0 absent; 3 severe). Forty-three with a positive test had pains (chest, back, arm, and/or jaw) (no SI), whereas 93 with a positive test did not (SI). Patients with SI and patients without SI did not differ as to age, gender, or clinical features (including presence of diabetes or a history of myocardial infarction), but patients with SI were less likely to report a history of effort-related chest pains. Patients with SI exercised longer and had a higher peak heart rate. Patients were comparable with respect to myocardial ischemia (ST segment depression, double product, thallium lung uptake, and positive thallium scintigrams) and severity of coronary disease. Patients with SI complained less of weakness (p < 0.02) and tended to have lower overall symptom scores (4.2 +/- 0.3 vs 5.4 +/- 0.6), but breathlessness was comparable for both groups. On multivariate analysis, no nonanginal symptom was associated with SI. Only absence of a history of chest pain with activity and longer exercise time were related to SI. Patients with SI have similar clinical features as those with angina but tend to be less symptomatic with myocardial ischemia even for symptoms other than chest pain.
