Dear Doctors: I wound up in the emergency room with a heart arrhythmia. It kept beating too fast, too slow and skipping beats, one after the other nonstop. They did an EKG but said it looked normal.

Research presented at the EUSEM Congress 2026 in Paris spans prehospital troponin testing, drone-delivered defibrillators, ...

Cardiac troponin, a protein released into the blood when heart muscle is damaged, can be used as a quick measure of heart ...

Troponins are proteins released into the bloodstream if there’s heart damage. Lab results below the 99th percentile mean normal function. Higher levels could mean a heart attack or another cardiac ...

A new meta-analysis of six randomized controlled trials finds that long-term exercise significantly attenuates cardiac ...

Rising troponin levels after exercise can help identify those at risk of cardiovascular disease or early death; the findings do not mean exercise is harmful. While exercise provides a variety of ...

This page lists all known medications that could potentially lead to 'Increase in Troponin' as a side effect. It's important to note that mild side effects are quite common with medications. The ...

A new Swedish analysis should serve as a reminder to physicians: elevated cardiac troponin, even in the absence of standard cardiac and noncardiac diseases known to cause a troponin rise, remains an ...

Cardiac troponin testing is central to the diagnosis of acute myocardial infarction. We evaluated a sensitive troponin I assay for the early diagnosis and risk stratification of myocardial infarction.

In most patients with stable coronary artery disease, plasma cardiac troponin T levels are below the limit of detection for the conventional assay. The distribution and determinants of very low ...

Dear Dr. Roach: I am a 77-year-old male who apparently suffered a case of food poisoning. I say apparently because no cause was ever discovered for the uncontrollable vomiting and diarrhea that lasted ...
