Objectives: Some authors have recommended troponin measurement to stratify patient mortality risk, but it is unclear whether troponin values add to age and routine admission laboratory tests in the prediction of in-hospital mortality of older adult patients without suspected acute coronary syndrome (ACS). The aim of our study was to…
Objectives: Cardiac troponin (cTn) measurement is useful for diagnosing myocardial infarction (MI), particularly in the inpatient setting. A growing body of literature suggests that cTn may be useful for evaluating chronic conditions in the outpatient environment; however, little is known regarding cTn ordering patterns in this setting. We sought to…
Objectives: ST elevation myocardial infarctions (STEMIs) and non-ST elevation myocardial infarctions (NSTEMIs) have differences that can be important to differentiate. Our primary hypothesis was that corrected QT (QTc) duration and troponin I levels were higher in STEMIs compared with NSTEMIs. The objective of our study was to compare STEMIs with…
Objectives: Guidelines have recommended that risk stratification be performed in patients diagnosed with an acute pulmonary embolism (PE). No study has described the use of risk stratification in routine clinical practice. The purpose of this study was to measure the frequency and impact of risk stratification on treatment decisions and…
Evidence suggests prognostic utility of troponin (Tn) serum concentrations for a variety of conditions. We sought to determine whether elevated concentrations early after anthracycline chemotherapy predict the development of left ventricular systolic dysfunction in adult patients with cancer. PubMed/MEDLINE searches identified original reports that assessed cardiac TnI or TnT within…
Background: Cardiac-specific troponin (Tn) serum concentrations have proved to be important diagnostic and prognostic markers for acute myocardial infarction. Elevated levels in the setting of noncardiac diseases such as intracerebral hemorrhage also may provide useful prognostic information regarding outcome. Methods: A systematic review of the English-language medical literature was performed…
Perioperative myocardial infarctions occur in 1 to 4% of unselected noncardiac surgical patients, and are associated with high mortality. Detection of these events can be challenging, because ‘typical’ symptoms of myocardial ischemia may not be present or may be masked in the perioperative period. Therefore, surveillance by means of intraoperative…
Anaphylaxis, acute coronary syndrome and pulmonary embolism are conditions commonly seen in the acute medical setting which can be difficult to diagnose. Delay in establishing the correct diagnosis can result in either delayed or inappropriate treatment, and subsequent morbidity and mortality. The cases we present highlight the necessity of good…
