Insights
Diagnosing acute coronary syndrome (ACS) can be challenging early on, as initial electrocardiogram (ECG) results may appear normal. Serial ECG monitoring is crucial for timely intervention in ACS patients, including ST-elevation myocardial infarction (STEMI).
Area of Science:
- Cardiology
- Clinical Medicine
- Diagnostic Imaging
Context:
- Acute coronary syndrome (ACS), encompassing acute myocardial infarction (AMI) and unstable angina (UA), is a leading cause of sudden cardiac death.
- Electrocardiogram (ECG) is vital for ACS diagnosis, but early-phase abnormalities can be subtle or absent.
- Timeliness of intervention is critical for effective treatment of ACS, especially ST-elevation myocardial infarction (STEMI).
Purpose:
- To highlight the diagnostic challenges of early-phase acute coronary syndrome (ACS) using electrocardiogram (ECG).
- To emphasize the necessity of serial ECG recordings and follow-up for accurate ACS diagnosis.
- To underscore the time-sensitive nature of effective interventions for ACS and ST-elevation myocardial infarction (STEMI).
Summary:
- Early diagnosis of acute coronary syndrome (ACS) is difficult due to potentially normal initial ECG findings.
- Serial ECG monitoring is recommended for patients with suspected ACS, even with unremarkable initial recordings.
- Prompt risk stratification and treatment are essential for improving outcomes in ACS and STEMI patients.
Impact:
- Improved early detection rates for acute coronary syndrome (ACS).
- Enhanced clinical decision-making through serial ECG interpretation.
- Facilitation of timely and effective interventions for life-threatening cardiac events like STEMI.
Abstract:
Acute myocardial infarction(AMI) and unstable angina(UA) are part of a spectrum of clinical disease collectively identified as acute coronary syndrome (ACS) which is the most common proximate cause of sudden cardiac death. In a diagnosis of ACS, electrocardiogram(ECG) is still important. But, it is somewhat difficult to find out abnormal findings of ECG when it is taken in early phase of ACS. Therefore, it is necessary to record ECG on several times and to follow up even if there is no ECG abnormalities at first recording. The effective interventions for patients with ACS, particularly ST-elevation MI(STEMI), are extremely time-sensitive. It is imperative that we evaluate efficient risk stratification, and effective treatment of patients with ACS as quickly as possible.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
