Resum:
BackgroundCancer and cardiovascular diseases are the leading causes of mortality worldwide, as they share common risk factors and exacerbate cardiovascular outcomes when they coexist. This study aimed to assess the clinical characteristics and cardiovascular outcomes of patients with a history of cancer and myocardial injury (MI) presenting with suspected acute coronary syndrome (ACS) in an emergency setting.MethodsThis retrospective cohort study included 3,626 patients admitted to the emergency department with suspected ACS between 2012 and 2013. Patients were categorized on the basis of their cancer history and the presence of MI. Clinical variables and the associations between cancer history and MI with all-cause mortality were analyzed over a four-year follow-up period via univariate and multivariate Cox regression models.ResultsOf the cohort, 10.6% (n = 384) had a history of cancer. Compared with other groups, cancer patients with MI were older, had more comorbidities, and presented a higher incidence of type 2 myocardial infarction (T2MI). At the four-year follow-up, all-cause mortality was significantly greater among cancer patients with MI (68.8%) than among cancer patients without MI (32.4%) and noncancer patients with or without MI (42.5% vs. 11.3%, respectively). Multivariate analysis identified cancer patients, particularly those with MI, as independent predictors of mortality.ConclusionsPatients who present to emergency departments with suspected ACS, a history of cancer, or the presence of MI face greater cardiovascular risk and mortality than other patients do. The higher prevalence of T2MI in this population underscores the need for tailored management strategies.
