Background: This research examines the role of systematic cardiac troponin evaluation in identifying type 1 myocardial infarction among patients presenting to the emergency department with collected blood samples.

Methods: This was a prospective study of consecutive adult patients presenting to the emergency department of a university hospital between October 22, 2020, and January 11, 2021. Cardiac troponin I levels were measured in all patients, including those with suspected acute coronary syndrome (clinical testing) and a control group undergoing routine blood tests (non-clinical testing).

Background: Cancer 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.

Methods: This retrospective cohort study included 3,626 patients admitted to the emergency department with suspected ACS between 2012 and 2013.

Introduction: Cardiac troponin levels below the 99th percentile improve the predictive efficacy for cardiovascular events when associated with relevant clinical variables. However, whether ultra-sensitive analytical methods improve this predictive efficacy over less sensitive or contemporary analytical methods remains unknown.

Methods: This retrospective observational study involved consecutive patients who presented to the emergency department for suspected acute coronary syndrome and underwent measurement of ultra-sensitive cardiac troponin I (Singulex) and contemporary cardiac troponin I (Siemens) with levels below the 99th percentile.
