Myocardial infarction without pain. A study of the sensory function of the upper limbs

Abstract
The sensory function of the upper limbs was examined in 18 patients who had a myocardial infarction without a well-defined episode of chest pain. The cutaneous pain threshold was significantly higher than normal. The ischemia of the upper limbs induced patterns of sensations different from normal, with the onset of pain, autonomic and cenesthesic disturbances. These modifications of the sensory function were the same in subjects with a previous painful infarction, but different from those observed in patients with angina pectoris.
