When it comes to heart health, early detection and accurate diagnosis are crucial. Cardiac imaging plays a vital role in identifying potential issues before they become serious. But with several types of heart imaging available, it can be confusing to know which one is right for you. In this blog, we’ll break down some of the most common types of cardiac imaging, including Calcium CT and Coronary Angiograms, to help you understand their purpose and benefits.
1. Coronary Calcium Scan (Calcium CT or Coronary Artery Calcium Score)
A Coronary Calcium Scan, also known as a Calcium CT(CAC), is a CT without the use of contrast dye that detects calcium deposits in the coronary arteries. When plaque gets into the major vessels that feed the heart muscle(coronary arteries), the CT can pick up the amount of calcium and which artery it is in. This test helps to quantify one's risk and can elevate or lower your cardiovascular risk score called your ASCVD risk score. You can find this risk calculator here. Both hospitals in town and RCI perform them. Unfortunately they are not covered by insurance but are $99 at all three locations.
How it works:
-
A CT scanner takes detailed images of your heart.
-
The presence of calcium deposits is measured and assigned a calcium score.
-
A higher score indicates a greater risk of heart disease.
Who should consider it?
-
Individuals with a family history of heart disease.
-
Those with risk factors such as high blood pressure, high cholesterol, smoking, or diabetes.
-
People concerned about their heart health but without symptoms.
What are the limitations of this test?
-
CAC does not differentiate between hard and soft plaques. Soft plaques are more inflamed and more volatile, more at risk for rupturing.
2. Coronary Angiogram
A Coronary Angiogram is a more invasive procedure used to evaluate blockages in the coronary arteries by the use of contrast dye and by the mechanism in which it's performed. It’s often recommended if a person is experiencing symptoms of heart disease, such as chest pain or shortness of breath, or can be the best step if one's CAC score is very elevated.
How it works:
-
A contrast dye is injected into the coronary arteries through a catheter.
-
X-ray imaging captures real-time movement of blood flow in the arteries.
-
Any narrowing or blockages in the arteries can be identified.
Who should consider it?
-
Individuals experiencing symptoms of coronary artery disease.
-
Those with abnormal stress test results.
-
People at high risk of a heart attack.
3. Echocardiogram
An Echocardiogram is an ultrasound of the heart that evaluates heart function and structure. It is non-invasive and commonly used to detect heart valve problems, heart failure, or congenital heart defects.
How it works:
-
Sound waves create images of the heart’s chambers, valves, and blood flow.
-
The test provides insights into heart muscle function and overall heart health.
Who should consider it?
-
Patients with unexplained shortness of breath or irregular heartbeats.
-
Individuals with a history of heart murmurs or valve disease.
-
Those being monitored for heart failure.
4. Stress Test (Exercise or Nuclear Stress Test)
A Stress Test assesses how the heart performs under physical exertion or induced by chemicals and can help diagnose coronary artery disease.
How it works:
-
The patient walks on a treadmill or is given a medication that mimics exercise.
-
Heart activity is monitored through an electrocardiogram (EKG) and sometimes imaging.
-
A nuclear stress test includes an injected tracer to visualize blood flow to the heart.
Who should consider it?
-
People with chest discomfort or symptoms triggered by activity.
-
Those with a family history of heart disease and risk factors.
-
Individuals needing heart function evaluation before surgery
Which Test is Right for You?
Each type of cardiac imaging serves a different purpose, and your doctor will recommend the most appropriate test based on your symptoms, risk factors, and medical history. If you’re concerned about your heart health, it’s always best to consult with a healthcare provider to determine which test will provide the most useful insights.
Prioritizing Prevention Prevention is key to maintaining heart health. If you're unsure about your heart disease risk, a Coronary Calcium Scan might be a good first step in assessing your long-term cardiovascular health.
