This is not a coincidence.

Coronary arteries are directly responsible for feeding the heart itself.

🩸 What Are Coronary Arteries?

Coronary arteries are the blood vessels that supply blood to the heart muscle.

They:

Without coronary arteries, the heart cannot function.

Why the Heart Needs Its Own Blood Supply

The heart is a muscle that works nonstop.

Even though it pumps blood to the whole body, the heart cannot use that blood for itself.

It needs a separate system — the coronary arteries — to stay alive.

What Happens When a Coronary Artery Narrows?

Over time, fatty deposits called plaque can build up inside a coronary artery.

When this happens:

This condition is called coronary artery disease.

What Causes a Heart Attack?

A heart attack happens when a coronary artery becomes suddenly blocked.

This usually occurs when:

Without oxygen, heart muscle cells begin to die within minutes.

Why Other Arteries Don't Cause Heart Attacks

Blockages in other arteries affect other organs.

Blockages in coronary arteries affect the heart itself.

Because the heart controls blood flow to the entire body, damage to it can quickly become life-threatening.

Why Coronary Arteries Are Easy to Miss

Coronary arteries:

This is why heart disease may progress without obvious warning signs.

Key Takeaway

Coronary arteries feed the heart muscle.

When they narrow or block, the heart is starved of oxygen — leading to heart disease or heart attack.
