Abstract
BACKGROUND: The frequency of noncardiac chest pain (CP) hospitalization after acute myocardial infarction (AMI) is unknown, and its significance from patients' perspectives is not studied.
OBJECTIVES: To assess the frequency of noncardiac CP admissions after AMI and its association with patients' self-reported health status.
METHODS: We identified cardiac and noncardiac CP hospitalizations in the year after AMI from the 24-center TRIUMPH registry. Hierarchical repeated-measures regression was used to identify the association of these hospitalizations with patients' self-reported health status using the Seattle Angina Questionnaire Quality of Life domain (SAQ QoL) and Short Form 12 (SF-12) physical (PCS) and mental (MCS) component summary scores.
RESULTS: Of 3,099 patients, 318 (10.3%) were hospitalized with CP, of whom 92 (28.9%) were hospitalized for noncardiac CP. Compared with patients not hospitalized with CP, noncardiac CP hospitalization was associated with poorer health status (SAQ QoL-adjusted differences: -8.9 points [95% CI -12.1 to -5.6]; SF-12 PCS: -2.5 points [95% CI -4.2 to -0.8] and SF-12 MCS: -3.5 points [95% CI -5.1 to -1.9]). The SAQ QoL for patients hospitalized with noncardiac CP was similar to patients hospitalized with cardiac CP (adjusted difference: 0.6 points [95% CI -3.2 to 4.5]; SF-12 PCS (0.9 points [95% CI -1.1 to 2.9]), but was worse with regard to SF-12 MCS (adjusted difference: -2.0 points [95% CI -3.9 to -0.2]).
CONCLUSIONS: Noncardiac CP accounted for a third of CP hospitalizations within 1 year of AMI and was associated with similar disease-specific QoL as well as general physical and mental health status impairment compared with cardiac CP hospitalization.
