Positive Exercise ECG Results: What You Need to Know - Cardiology

More Info

---

Understanding the implications of a positive exercise ECG (electrocardiogram) result can be quite concerning, especially when accompanied by symptoms such as chest tightness and shortness of breath. Based on the information provided, it appears that your exercise ECG has indicated signs of myocardial ischemia, which is a condition where the heart muscle does not receive enough blood and oxygen during physical activity.


Key Findings from Your Report
1. Maximal Heart Rate and Exercise Duration: You achieved a maximal heart rate of 162 bpm, which is approximately 91% of your predicted maximal heart rate. This indicates that you were able to exert yourself significantly during the test.

2. Resting ECG: Your resting ECG showed a normal sinus rhythm but noted a right axis deviation (RAD) and ST-T changes, specifically ST depression greater than 1 mm. These findings can sometimes indicate underlying heart issues.

3. Exercise-Induced Changes: During the exercise, you exhibited horizontal ST depression of 1-2 mm in leads III, aVF, V4, V5, and V6 at stage 4 of the Bruce protocol. This is a significant finding as ST segment depression during exercise can suggest that the heart is not receiving adequate blood flow, particularly under stress.

4. Blood Pressure Response: Your blood pressure increased from 130/86 mmHg at rest to 176/77 mmHg at peak exercise, which is a normal physiological response to exercise.

5. Conclusion: The report concludes with a positive result for myocardial ischemia, which is concerning and warrants further investigation.


Next Steps and Recommendations
Given the positive exercise ECG result, it is crucial to follow up with your healthcare provider for further evaluation. Here are some potential next steps:
1. Coronary Angiography: Your doctor has suggested a coronary catheterization (heart catheterization) to visualize the coronary arteries directly. This procedure can help determine if there are blockages or significant narrowing in the arteries that supply blood to your heart.

2. Medication Management: You are currently taking Nicorandil, which is a medication that helps to improve blood flow to the heart. It is essential to continue monitoring your blood pressure and cholesterol levels, as these factors can significantly impact your heart health.

3. Lifestyle Modifications: Maintaining a healthy lifestyle is crucial. This includes regular exercise, a balanced diet low in saturated fats and cholesterol, and managing stress levels. Since you mentioned having anxiety, it might be beneficial to explore stress management techniques such as mindfulness, yoga, or counseling.

4. Regular Monitoring: Keep regular appointments with your healthcare provider to monitor your heart health, especially given your history of elevated blood pressure and cholesterol levels.

5. Further Testing: Depending on the results of the coronary angiography, your doctor may recommend additional tests or treatments, such as a myocardial perfusion scan or adjustments to your medication regimen.


Conclusion
In summary, while your exercise ECG results indicate potential myocardial ischemia, it is essential to approach this situation with a comprehensive plan involving further diagnostic testing and lifestyle adjustments. It is understandable to feel anxious about these findings, but with appropriate medical guidance and intervention, many individuals can manage their heart health effectively. Always communicate openly with your healthcare provider about your symptoms and concerns, and do not hesitate to seek a second opinion if needed.
