Exercise ECG Results: What Your Heart Health Report Means - Cardiology

More Info

---

Understanding the results of an exercise ECG (electrocardiogram) is crucial for assessing heart health, especially in the context of symptoms like chest pain or discomfort during physical activity. Based on the details you provided, let's break down the findings and their implications.


Overview of Your Symptoms and Test Results
You mentioned experiencing occasional chest discomfort while playing basketball, and a recent episode of chest pain at rest, which prompted further evaluation. Your lipid profile indicates a total cholesterol level of 203 mg/dL, with low-density lipoprotein (LDL) at 137 mg/dL, high-density lipoprotein (HDL) at 51 mg/dL, and triglycerides at 86 mg/dL. While your total cholesterol is slightly above the recommended level, your LDL is borderline high, which could be a concern for cardiovascular health. However, your HDL is within a normal range, which is protective against heart disease.

The creatine kinase (CK) level of 429 U/L, especially after intense physical activity, can be elevated due to muscle strain or injury, and it may not necessarily indicate heart damage unless accompanied by other symptoms or elevated troponin levels.


Exercise ECG Findings
Your exercise ECG report indicates that you achieved a maximum heart rate of 173 bpm, which is 90% of the predicted maximum heart rate of 192 bpm. The test was terminated because you reached your target heart rate, and you did not experience significant symptoms during the test, only mild shortness of breath.
The interpretation of the exercise ECG shows an abnormal ST segment depression of -1.1 mm at lead III during stage 5 of the test. ST segment depression can indicate myocardial ischemia, which occurs when the heart muscle does not receive enough blood and oxygen, often due to narrowed coronary arteries.


Potential for False Positives
It is important to note that exercise ECGs can yield false-positive results, particularly in individuals who are physically fit or have a high level of exercise tolerance. Factors such as anxiety, technical issues with the ECG leads, or even the presence of a non-cardiac condition can contribute to these results. Given that you did not experience chest pain or significant discomfort during the test, the abnormal ST segment depression may warrant further investigation but does not definitively indicate coronary artery disease (CAD).


Recommendations for Further Evaluation
1. Consultation with a Cardiologist: Given the abnormal findings, it would be prudent to discuss these results with a cardiologist. They may recommend further testing, such as a coronary angiogram or a stress echocardiogram, to assess the coronary arteries more directly.

2. Lipid Management: Your lipid profile suggests that you may benefit from lifestyle modifications, including dietary changes and increased physical activity. Depending on your overall risk factors, your doctor may also consider medication to manage your cholesterol levels.

3. Monitoring Symptoms: Keep track of any recurrent symptoms, especially chest pain or discomfort, and report these to your healthcare provider. If symptoms worsen or new symptoms arise, seek immediate medical attention.

4. Consider a Holter Monitor: If there are concerns about arrhythmias or other heart rhythm issues, a Holter monitor may be recommended to assess your heart's electrical activity over a 24-hour period.


Conclusion
In summary, while your exercise ECG shows some concerning signs, the absence of symptoms during the test and your overall health profile suggest that further evaluation is necessary to clarify your heart health status. Engaging in a dialogue with your healthcare provider about these findings will help determine the best course of action for your cardiovascular health. Remember, proactive management and regular monitoring are key to maintaining heart health, especially when there are risk factors present.
