McLaren Central Michigan has launched coronary artery calcium (CAC) scoring to help patients quantify their risk of heart disease through noninvasive, low-dose CT imaging. According to the hospital, this procedure measures calcium buildup in the coronary arteries to produce a risk score between 1 and 1,000, allowing for proactive medical interventions. The service is available for a $150 self-pay fee or via referral from a primary care provider.
How does a CAC score determine heart disease risk?
A coronary artery calcium score provides a numerical snapshot of plaque buildup within the heart’s arteries. Dr. Marina Maraskine, an interventional cardiologist at McLaren Central Michigan, explains that this scan identifies “hidden risk” before a patient experiences a cardiac event. The test uses a low-dose CT scan that avoids the need for IVs or contrast dye. Scores are categorized on a scale of 1 to 1,000, where higher numbers indicate a more significant presence of calcified plaque and a higher likelihood of future heart complications.
Who should consider a cardiac calcium screening?
Medical providers generally recommend CAC scoring for individuals who have risk factors but may not show symptoms of heart disease. According to clinical guidelines provided by McLaren Central Michigan, adults over the age of 45 with specific health indicators should evaluate the test. These indicators include:
- High blood pressure (hypertension)
- Elevated cholesterol levels
- Tobacco use
- Type 2 diabetes
- High body mass index (BMI)
- Family history of early heart disease
What should patients expect during the procedure?
The entire process is designed for efficiency and minimal patient disruption. The scan itself takes roughly 10 to 15 minutes, while the total appointment time is usually between 20 and 30 minutes. Once the imaging is complete, the results are sent to the patient and their primary care physician. This collaboration ensures that any necessary follow-up care, lifestyle changes, or treatment plans are integrated into the patient’s existing health management strategy.
CAC scoring is often used by cardiologists to guide “earlier conversations” about prevention. By visualizing the physical buildup of plaque, patients are often more motivated to adopt lifestyle changes or begin preventative treatments before a medical crisis occurs.
How to access screening services
Patients can access these services through a standard referral or by attending specific screening events. McLaren Central Michigan hosts periodic evaluation events where attendees can meet with Dr. Maraskine to determine if they meet the clinical criteria for the scan. For those ready to schedule a test immediately, the hospital directs inquiries to their imaging department at (989) 772-6796. Patients without a primary care provider can also connect with one via mclaren.org/appointments.
Frequently Asked Questions
Is the CAC scan painful?
No. The procedure is noninvasive and does not require the use of IVs or contrast dye, making it a comfortable experience for most patients.
Does insurance cover this test?
The test is currently available as a $150 self-pay service. Because insurance authorization is not required, patients can obtain the scan directly without navigating complex insurance approval processes.
How long does it take to get results?
The scan takes approximately 10 to 15 minutes. Results are then forwarded to your primary care provider for review and to discuss any required next steps.
Do I need a doctor’s order?
Yes, a referral or an order is required. During special screening events, Dr. Maraskine can provide an evaluation and write the order on-site for those who meet the necessary criteria.
