MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We wanted to investigate how the introduction of the new high-sensitivity cardiac troponin T (hs-cTnT) assay affected incidence of myocardial infarction (MI) use of coronary angiography, cardiac revascularizations, and prognosis in patients with myocardial infarction.

We found that the incidence of MI increased by approximately 5%, with no change in mortality, but with an 11% reduced risk of reinfarctions, and a small increase in coronary angiographies, and cardiac revascularizations by 16%, and 13%, respectively.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Approximately 10 million patients present to emergency rooms in the US annually for evaluation of acute chest pain.

The goal of that evaluation is to rule out the diagnosis of an acute heart attack. Imaging with coronary CT angiography and stress testing are not part of the diagnostic algorithm for acute heart attack.  Nevertheless many chest pain patients undergo some form of noninvasive cardiac testing in the ER. We found that CCTA or stress testing adding nothing to the care of chest pain patients beyond what is achieved by a history, physical examination, ECG and troponin test.
