Background: The rate-limiting step in STEMI diagnosis often is the availability of a 12-lead electrocardiogram (ECG) and its interpretation. The potential may exist to speed the availability of 12-lead ECG information by using commonly available mobile technologies. We sought to test whether combining serial smartphone single-lead ECGs to create a virtual 12-lead ECG can accurately diagnose STEMI.

Unfortunately, biosecurity and biosafety are often under-prioritized nationally, regionally, and globally. Security leaders often deemphasize accidental and deliberate biological threats relative to other challenges to peace and security.

- Rapid diagnosis and access to reperfusion therapy are crucial for optimal outcomes in STEMI patients.
- The ST LEUIS study aims to validate a smartphone ECG app against traditional 12-lead ECGs for detecting STEMI in chest pain patients.
- Conducted over 12 months at five institutions, the study plans to enroll 300 patients to assess the app's diagnostic accuracy.
Background: Diagnostic testing in the care of patients newly presenting with symptoms suggestive of coronary artery disease may influence risk factor management, independent of test type or test results. However, little is known about changes in medications and lifestyle after anatomical or functional testing.
Methods And Results: We examined what factors influenced preventive medical therapy and lifestyle practices at 60 days among 10 003 symptomatic patients (53% women; mean age 61 years) randomly assigned to anatomical testing with coronary computed tomographic angiography or functional testing (NCT01174550).
