Abstract

Background: Little is known about patients with cancer presenting with acute chest discomfort to the emergency department (ED).

Objectives: The aim of this study was to assess the prevalence of acute myocardial infarction (AMI), outcomes, and the diagnostic utility of recommended diagnostic tools in this population.

Methods: Patients presenting with chest pain to the ED were prospectively enrolled in an international multicenter diagnostic study with central adjudication. Cancer status was assessed prospectively and additional cancer details retrospectively. Findings were externally validated in an independent multicenter cohort.

Results: Among 8,267 patients, 711 (8.6%) had cancer. Patients with cancer had a higher burden of cardiovascular risk factors and pre-existing cardiac disease. Total length of stay in the ED (5.2 hours vs 4.3 hours) and hospitalization rate (49.8% vs 34.3%) were both increased in patients with cancer (P < 0.001 for both). Among 8,093 patients eligible for the AMI analyses, those with cancer more often had final diagnoses of AMI (184 of 686 with cancer [26.8%] vs 1,561 of 7,407 without cancer [21.1%]; P < 0.001). In patients with cancer, high-sensitivity cardiac troponin T (hs-cTnT) but not high sensitivity cardiac troponin I (hs-cTnI) concentration had lower diagnostic accuracy for non-ST-segment elevation myocardial infarction (for hs-cTnT, area under the curve: 0.89 [95% CI: 0.86-0.92] vs 0.94 [95% CI: 0.93-0.94] [P < 0.001]; for hs-cTnI, area under the curve: 0.93 [95% CI: 0.91-0.95] vs 0.95 [95% CI: 0.94-0.95] [P = 0.10]). In patients with cancer, the European Society of Cardiology 0/1-hour hs-cTnT and hs-cTnI algorithms maintained very high safety but had lower efficacy, with twice the number of patients remaining in the observe zone. Similar findings were obtained in the external validation cohort.

Conclusions: Patients with cancer have a substantially higher prevalence of AMI as the cause of chest pain. Length of ED stay and hospitalization rates are increased. The diagnostic performance of hs-cTnT and the efficacy of both the European Society of Cardiology 0/1-hour hs-cTnT and hs-cTnI algorithms is reduced.

Patients With Cancer Presenting to the ED With Chest Pain Among 8,267 patients, 711 (8.6%) had active or past cancer. The prevalence of index non–ST-segment elevation myocardial infarction (NSTEMI) was higher and the prevalence of noncardiac chest pain was lower in patients with cancer compared with those without cancer. Hospitalization rate and length of stay in the emergency department (ED) were also higher in patients with cancer. The diagnostic performance of high-sensitivity cardiac troponin T (hs-cTnT), but not that of high-sensitivity cardiac troponin I (hs-cTnI), was reduced in patients with cancer. The European Society of Cardiology (ESC) 0/1-hour algorithms for both hs-cTnT and hs-cTnI maintained very high safety for rule-out, although the observe-zone proportion was higher, and specificity for rule-in was lower in patients with cancer.
