Coronary Atherosclerosis: Diagnosis, Treatment, and Risks

Autologous coronary atherosclerosis

My mother was found to have high cholesterol and triglycerides during a health check-up, so she visited a cardiologist a few days ago.
The doctor performed a standard electrocardiogram (ECG) and, according to my mother, mentioned that there seemed to be some issues.
Consequently, blood tests were conducted, and she underwent a stress test with ECG.
Today, after the stress test, my mother said the doctor suggested she might need to undergo some catheterization.
The doctor prescribed Zolotin 20 mg and Bokey 100 mg for her.

The blood test results are as follows: Sodium 144 mmol/L, Potassium 4.6 mmol/L, Cholesterol 245 mg/dL, Triglycerides 401 mg/dL, Fasting Blood Sugar 124 mg/dL, Creatinine 0.79 mg/dL, GPT 51 IU/L, High-Density Lipoprotein (HDL) 54.5 mg/dL.
The report indicated a diagnosis of "autologous coronary atherosclerosis."
I would like to ask the doctor:
1.
Can coronary atherosclerosis be detected solely through a stress ECG?
2.
Is catheterization absolutely necessary? My mother doesn't seem to have any significant discomfort.
Can it be managed with medication alone?
3.
Is the risk associated with coronary atherosclerosis high? Is there an urgent need for catheterization?
4.
What are the risks associated with catheterization? Are there any potential complications or adverse effects after the procedure?
Thank you, doctor!

More Info

Understanding coronary atherosclerosis is crucial for managing heart health, especially when risk factors such as high cholesterol and triglycerides are present. Your mother's recent health evaluations and the subsequent recommendations from her cardiologist indicate a proactive approach to her cardiovascular health. Let’s address your questions one by one.

1. Can coronary atherosclerosis be detected solely through a stress electrocardiogram (ECG)?
A stress ECG can provide valuable information about the heart's function under physical stress, but it is not definitive for diagnosing coronary atherosclerosis. While it can indicate potential ischemia (reduced blood flow to the heart), it does not directly visualize the arteries or the presence of atherosclerosis. Additional imaging techniques, such as coronary angiography or non-invasive imaging like a coronary CT angiogram, are often required to confirm the presence and severity of coronary artery disease (CAD).

2. Is catheterization necessary? Can medication alone be sufficient?
The decision to perform catheterization (coronary angiography) depends on several factors, including the results of the stress test, the presence of symptoms, and the overall risk profile. If the stress test indicates significant ischemia or if there are concerning symptoms, catheterization may be warranted to visualize the coronary arteries directly and assess for blockages. However, if your mother is asymptomatic and her risk factors are being managed effectively with medication, her doctor may opt to monitor her condition with lifestyle changes and medication alone. Medications like statins (for cholesterol) and antihypertensives can significantly reduce cardiovascular risk.

3. What is the risk associated with coronary atherosclerosis? Is there an urgency for catheterization?
Coronary atherosclerosis can lead to serious complications, including heart attacks and angina. The urgency for catheterization depends on the severity of the disease and the presence of symptoms. If there is evidence of significant blockage or if your mother experiences symptoms like chest pain or shortness of breath, prompt intervention may be necessary. However, if she is stable and asymptomatic, her doctor may recommend a conservative approach with regular follow-ups.

4. What are the risks associated with catheterization? Are there potential complications?
Coronary angiography is generally considered safe, but like any medical procedure, it carries some risks. These can include bleeding at the catheter insertion site, allergic reactions to the contrast dye, kidney damage (especially in patients with pre-existing kidney issues), and, in rare cases, heart attack or stroke. Most patients recover quickly and experience minimal complications. Discussing these risks with the cardiologist can help you understand the necessity of the procedure in your mother's case.

In summary, coronary atherosclerosis is a significant health concern that requires careful monitoring and management. While a stress ECG can provide initial insights, further testing may be necessary to assess the condition accurately. Medication can be effective in managing risk factors, but the decision for catheterization should be based on a comprehensive evaluation of your mother's health status and risk factors. Regular follow-ups with her healthcare provider will be essential in ensuring her cardiovascular health is maintained. Encourage her to maintain a heart-healthy lifestyle, including a balanced diet, regular exercise, and adherence to prescribed medications.
