Coronary microvascular disease (MVD) is a real condition — and yes, others in the heart disease community have heard of it! It affects the tiny blood vessels that branch off the coronary arteries, making it harder for the heart to get the blood flow it needs. It can be tricky to diagnose because standard tests don't always catch it.
Here are some common ways it can be diagnosed:
- Electrocardiogram (ECG/EKG) — checks the heart's electrical activity and rhythm
- Echocardiogram — uses sound waves to create images of the heart's structure and function
- Cardiac MRI — gives a detailed picture of the heart muscle and blood flow
- Cardiac catheterization — a thin tube is guided through a blood vessel to measure blood flow directly
- Stress testing — checks how the heart performs under physical or medication-induced stress
- Blood tests — can detect proteins that signal heart stress or damage
Since MVD involves small vessels, a cardiologist may need to use specialized imaging or pressure measurements during catheterization to confirm it. It's worth having an open conversation with a cardiologist if MVD is suspected, as getting the right diagnosis is key to finding the right treatment.
