Insights
Many cardiologists are unaware of ST-segment monitoring guidelines. Implementing hospital standards for continuous ST-segment monitoring can improve its use for cardiac patients.
Area of Science:
- Cardiology
- Medical Technology
- Clinical Practice
Background:
- Continuous ST-segment monitoring aids in early detection of transient cardiac ischemia.
- Guidelines recommend its use in specific patient populations, yet adoption in US hospitals is inconsistent.
Purpose of the Study:
- To assess cardiologists' awareness of continuous ST-segment monitoring guidelines.
- To evaluate their practice standards, patient selection, perceived benefits, barriers, and technology usefulness.
Main Methods:
- An electronic survey was distributed to 915 US cardiologists.
- Data were collected on awareness, practice standards, and perceptions of ST-segment monitoring.
Main Results:
- 55% of cardiologists were unaware of consensus guidelines for ST-segment monitoring.
- Only 49% of hospitals had a standard practice for its use.
- High agreement existed for monitoring in cardiovascular labs and ICUs; routine use was common for acute coronary syndrome and post-PCI patients.
- Hospital standards of practice and guideline awareness were linked to higher perceived benefits and use.
Conclusions:
- A significant portion of cardiologists lack awareness of published ST-segment monitoring guidelines.
- Hospital leadership can enhance awareness and adoption through evidence review and integrating monitoring into standard practices.
Background:
Continuous ST-segment monitoring can be used to detect early and transient cardiac ischemia. The American Heart Association and American Association of Critical-Care Nurses recommend its use among specific patients, but such monitoring is routine practice in only about half of US hospitals.
Objective:
To determine cardiologists' awareness and practice standards regarding continuous ST-segment monitoring and the physicians' perceptions of appropriate patient selection, benefits and barriers, and usefulness of this technology.
Methods:
An electronic survey was sent to a random sample of 915 US cardiologists from a pool of 4985 certified cardiologists.
Results:
Of 200 responding cardiologists, 55% were unaware of the consensus guidelines. Of hospitals where respondents admitted patients, 49% had a standard of practice for using continuous ST-segment monitoring for cardiac patients. Most cardiologists agreed or strongly agreed that patients in the cardiovascular laboratory (87.5%) and intensive care unit (80.5%) should have such monitoring. Cardiologists routinely ordered ST monitoring for patients with acute coronary syndrome (67%) and after percutaneous coronary intervention (60%). The primary factor associated with higher perceptions for benefits, clinical usefulness, and past use of continuous ST-segment monitoring was whether or not hospitals in which cardiologists practiced had a standard of practice for using this monitoring. A secondary factor was awareness of published consensus guidelines for such monitoring.
Conclusion:
Respondents (55%) were unaware of published monitoring guidelines. Hospital leaders could raise awareness by multidisciplinary review of evidence and possibly incorporating continuous ST-segment monitoring into hospitals' standards of practice.

Electrocardiogram Fundamentals
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.

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.
