Pain recollection after chest pain of cardiac origin.
Memory for pain is an important research and clinical issue since patients ability to accurately recall pain plays a prominent role in medical practice. The purpose of this prospective study was to find out if patients, with an episode of chest pain due to suspected acute myocardial infarction could accurately retrieve the pain initially experienced at home and during the first day of hospitalization after 6 months. A total of 177 patients were included in this analysis. The patients rated their experience of pain on a numerical rating scale. The maximal pain at home was retrospectively assessed, thereafter pain assessments were made at several points of time after admission. After 6 months they were asked to recall the intensity of pain and once again rate it on the numerical rating scale. The results from the initial and 6-month registrations were compared. In general, patients rated their maximal intensity of chest pain as being higher at the 6-month recollection as compared with the assessments made during the initial hospitalization. In particular, in patients with a high level of emotional distress, there was a systematic overestimation of the pain intensity at recall.
