Abstract:
In the era of high-sensitivity troponin, minor elevations are often attributed to noncardiac etiologies. However, in patients who present with characteristic symptoms, any troponin elevation is concerning. We detail a case of a 37-y-old woman who presented to an outside hospital with typical chest pain and had a mild elevation in high-sensitivity troponin. Given her overall stability, she was discharged with outpatient cardiology follow-up. 82Rb PET/CT myocardial perfusion imaging test demonstrated a large, reversible anteroseptal perfusion defect. Coronary angiography revealed severe (80%) stenosis in the proximal left anterior descending artery treated with a single stent. This case highlights the need to have a high index of suspicion in young people with minor troponin elevations and pursue timely imaging.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
Imaging Studies for Cardiovascular System I:Echocardiography
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
