Plain-language interpretation

• Main finding: About two small, calcified plaques are present at the opening of the ramus intermedius, a small branch of the left coronary artery.
• These cause minimal narrowing, less than 25% of the vessel diameter.
• The left main, LAD, circumflex, and right coronary artery are otherwise reported as normal.
• No obstructive coronary artery disease is seen. In other words, there is no narrowing severe enough on this scan to restrict blood flow.
• Right coronary dominance is a common normal anatomical pattern.
• No anomalous origin/course of the coronary arteries was seen.

What the scores mean

• CAD-RADS 1: Minimal non-obstructive coronary artery disease, defined as plaque with 1% to 24% narrowing. This category generally does not require invasive angiography or a stent based on the scan alone. It calls for attention to prevention and cardiovascular risk factors. The CAD-RADS consensus uses this category for minimal stenosis.
• P1: Indicates a mild overall plaque burden.
• Calcium score 13.4: This is a low, but non-zero, calcium score. It confirms that some calcified atherosclerotic plaque is present. It is not a high score, but it is a reason to take prevention seriously rather than treating the scan as completely normal.

Practical meaning

1. Blood pressure
2. Full lipid profile, particularly LDL cholesterol and non-HDL cholesterol
3. Diabetes screening: fasting glucose and/or HbA1c
4. Smoking or tobacco use
5. Weight, diet, physical activity, and family history of early heart disease
6. Whether cholesterol-lowering treatment, such as a statin, is appropriate based on the total risk profile. Do not start aspirin or any medication solely from this report without the clinician’s advice.
