Coronary Artery Disease CAD-RADS 3: Understanding Moderate Coronary Stenosis

Coronary artery disease (CAD) classified as CAD-RADS 3 indicates a moderate level of stenosis in the coronary arteries, specifically a narrowing of 50% to 75%. This classification is determined through advanced imaging techniques such as coronary computed tomography angiography (CTA), which is a non-invasive method, or through invasive coronary angiography, a minimally invasive procedure. The CAD-RADS (Coronary Artery Disease – Reporting and Data System) classification helps physicians assess the severity of coronary artery narrowing and guide appropriate treatment strategies.

Diagnosis and Assessment of CAD-RADS 3

The CAD-RADS system provides a standardized approach to reporting the severity of coronary artery blockages. A score of 3 within this system reflects a significant but not critically severe narrowing of the coronary arteries. This level of stenosis suggests that blood flow to the heart muscle may be partially restricted, which could lead to symptoms such as chest pain or shortness of breath during physical exertion.

Non-Invasive and Invasive Diagnostic Tools

Coronary CTA is often the first-line diagnostic tool for patients suspected of having coronary artery disease. It allows for detailed visualization of the coronary arteries without the need for surgery. In cases where more precise evaluation is required, invasive coronary angiography may be performed. Both methods are essential in determining the exact extent of arterial narrowing and in planning subsequent management strategies.

Treatment Approach for CAD-RADS 3 Patients

Patients diagnosed with CAD-RADS 3 typically do not require immediate interventional procedures such as stent placement. Instead, the primary treatment involves long-term pharmacological therapy aimed at managing symptoms, reducing the risk of cardiovascular events, and slowing the progression of atherosclerosis. Medications commonly prescribed include statins for lipid control, beta-blockers to reduce heart strain, antiplatelet agents like aspirin to prevent clot formation, and ACE inhibitors or ARBs for blood pressure regulation.

Importance of Lifestyle Modifications and Monitoring

In addition to medication, lifestyle changes play a crucial role in managing CAD-RADS 3. These include adopting a heart-healthy diet, engaging in regular physical activity, quitting smoking, and managing stress. Patients are advised to follow up regularly with their healthcare providers to monitor disease progression and adjust treatment plans as necessary.

Should symptoms worsen or if there is evidence of increased ischemia on follow-up electrocardiograms (ECGs), further evaluation with stress testing or repeat imaging may be warranted. In such cases, consideration for invasive interventions like percutaneous coronary intervention (PCI) may become necessary.
