Very early risk modeling in patients with chest pain based on the pattern on admission ECG
Insights
Admission electrocardiogram (ECG) ischemic patterns predict major adverse cardiac events (MACE) in chest pain patients. Combining ECG with cardiac troponin levels identifies the highest-risk individuals for MACE.
Area of Science:
- Cardiology
- Emergency Medicine
- Diagnostic Imaging
Background:
- Accurate and rapid assessment of chest pain is crucial in emergency settings.
- Electrocardiogram (ECG) is a standard initial diagnostic tool for suspected cardiac chest pain.
Purpose of the Study:
- To evaluate the prognostic accuracy of admission ECG in chest pain patients.
- To identify patients at highest risk for adverse outcomes.
Main Methods:
- Prospective enrollment of adult patients with suspected acute myocardial infarction (AMI).
- Analysis of admission ECG changes, cardiac troponin levels, and AMI diagnosis.
- One-year observation for major adverse cardiac events (MACE).
Main Results:
- Ischemic ECG patterns independently predicted MACE (HR 2.996, p=0.009).
- High-sensitivity cardiac troponin T (hs-cTnT) alone was not a significant predictor (HR 1.79).
- The combination of ischemic ECG and positive hs-cTnT identified the highest-risk group for MACE (HR 3.19, p=0.003).
Conclusions:
- Ischemic ECG changes in patients with suspected AMI increase MACE risk.
- Stratification using admission hs-cTnT measurement further refines identification of high-risk patients.
- These findings aid in risk stratification for chest pain patients in the emergency department.
Objectives:
The aim was to investigate the prognostic accuracy of admission ECG and its usefulness in determining the population at the highest risk of worse outcomes.
Background:
Fast and accurate assessment of chest pain patients remains a challenge for clinicians. Electrocardiogram (ECG) is performed in each case of suspicion of the cardiac origin of chest pain.
Methods:
Consecutive adult chest pain patients with suspicion of acute myocardial infarction (AMI) were enrolled in the study. The prognostic value of admission ECG changes alone and in combination with other clinical variables (cardiac troponin, diagnosis of AMI) were analyzed for the incidence of major adverse cardiac events (MACE) in a one‑year observation.
Results:
The ischemic pattern on admission ECG was a single risk factor of MACE (HR 2.996 95% CI 1.31-6.86, p = 0.009), contrary to the single admission high-sensitivity cardiac troponin T assay (hs-cTnT) (HR 1.79 95% CI 0.695-4.61). The highest risk of MACE was identified in case of the presence of both ischemic-ECG and positive hs-cTnT (HR 3.19 95% CI 1.496-6.81, p = 0.003).
Conclusions:
The presence of ischemic changes in ECG in chest pain population with AMI suspicion increases the risk of MACE. The group at highest risk of MACE can by identified by the additional stratification with the admission single hs-TnT measurement (Tab. 2, Fig. 4, Ref. 40).

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.
