Based on the context provided, the following statements are true:
-
Helen’s results indicate the presence of STEMI. - ST segment elevation indicates that she is likely experiencing a ST-Elevation Myocardial Infarction (STEMI), which is a type of heart attack.
-
The ECG results help explain why Helen was experiencing angina equivalents. - Angina equivalents can be caused by myocardial ischemia, which could result from a STEMI; therefore, the ECG findings help explain her symptoms.
The remaining statements are not accurate:
-
An ECG is the most definitive diagnostic test for an MI. - While the ECG is extremely useful for diagnosing myocardial infarction and can show changes like ST segment elevation, cardiac biomarkers (such as troponin levels) are considered more definitive for confirming an MI.
-
The ST segment elevation is a positive indicator for adequate perfusion of the heart. - This statement is incorrect; ST segment elevation indicates a lack of adequate perfusion due to obstruction, as seen in an MI.
-
Helen’s ECG indicates the next appropriate step is for Helen to be sent home with instructions to rest and drink plenty of fluids. - This statement is also false; an individual with ST segment elevation likely requires immediate medical intervention, such as reperfusion therapy (e.g., PCI or thrombolytics), and should not be sent home.
In summary, the true statements are:
- Helen’s results indicate the presence of STEMI.
- The ECG results help explain why Helen was experiencing angina equivalents.
