Chest pain, shortness of breath, unusual fatigue, or simply the need to check your heart health: it is not always easy to know when to seek medical advice or which tests to prioritize.
Cardiovascular health plays an important role in overall well-being and can influence many aspects of quality of life. Today, various cardiac tests and cardiac imaging techniques provide useful information about the heart’s function and structure.
In Montreal, access to tests such as the electrocardiogram (ECG), echocardiogram, cardiac CT scan, or cardiac MRI contributes to a more comprehensive evaluation, depending on individual needs and medical recommendation.
At Radiméd, we believe that a better understanding of cardiac tests can help guide appropriate care.
In this article, we answer the 5 most frequently asked questions about cardiac tests to help you better understand the available options.
1. How can I tell if my heart is healthy?
Assessing heart health generally relies on several combined elements: your medical history, your symptoms, a clinical examination, and, if needed, additional cardiac tests.
There is no single test that can evaluate everything, but rather different approaches that can provide an overall picture of heart health.
Commonly used tests include:
- Electrocardiogram (ECG): records the heart’s electrical activity to detect certain rhythm abnormalities
- Echocardiogram: uses ultrasound to observe the valves, chambers, and heart muscle in real time
- Stress test: evaluates how the heart responds to controlled physical exertion
- Advanced cardiac imaging (MRI or cardiac CT scan): can provide detailed images of the heart’s structure and surrounding tissues
A healthcare professional can determine which cardiac tests are appropriate for your situation.
2. When should I seek medical advice for a cardiac test?
A cardiac test may be considered in different situations, with or without symptoms.
When symptoms are present
Certain signs may warrant a medical consultation:
- Chest pain or discomfort
- Unusual shortness of breath
- Palpitations
- Dizziness or unexplained fatigue
These symptoms should lead to a medical evaluation to determine whether testing is necessary.
For prevention
Even in the absence of symptoms, a cardiac test may be recommended if you have risk factors such as:
- High blood pressure
- High cholesterol
- Diabetes
- Family history of heart disease
- Sedentary lifestyle
Cardiovascular screening can help provide a better understanding of overall risk.
3. Which test can check the heart’s arteries?
The coronary arteries, which supply blood to the heart muscle, can be evaluated using certain cardiac imaging techniques.
A cardiac CT scan (coronary CT) can be used to visualize the arteries and detect the presence of calcifications or plaque.
The calcium score, in turn, measures the amount of calcium in the coronary arteries, which can help estimate cardiovascular risk.
These tests are generally ordered based on the patient’s profile and medical assessment.
4. Are cardiac tests painful?
One of the common concerns is the discomfort associated with testing. It is reassuring to know that the vast majority of cardiac tests performed at Radiméd are non-invasive and well tolerated by patients. Whether it is an echocardiogram or a cardiac CT scan, these procedures are designed with your comfort in mind.
Although some tests may require mild physical exertion during a treadmill stress test, or the injection of a contrast agent during certain scans to improve image clarity, these interventions are safe, supervised by qualified professionals, and generally brief in duration.
5. Do I need a prescription for a cardiac test?
Yes. In Quebec, cardiology and cardiac imaging tests require a medical prescription.
Your doctor can:
- Assess your symptoms
- Identify the appropriate tests
- Write a suitable requisition
Once you have obtained your prescription, you can schedule your test at a medical imaging clinic in Montreal, such as Radiméd.
Toward better management of your heart health
Taking care of your cardiovascular health involves a combination of prevention, medical follow-up, and, when necessary, appropriate testing.
