10 Indicators of Blocked or Narrowed Arteries You Shouldn’t Ignore
“Blocked arteries” can refer to plaque buildup in different parts of the body. Importantly, many people with atherosclerosis have no symptoms until blood flow becomes significantly reduced, so symptoms alone cannot diagnose a blockage. Mayo Clinic+1
Here are 10 signs worth taking seriously:
-
Chest pressure, squeezing, or pain — particularly during exertion, which can occur when the heart isn’t receiving enough blood. Mayo Clinic
-
Shortness of breath — especially with activity or together with chest discomfort. Mayo Clinic
-
Pain or cramping in the calf while walking — pain that consistently starts with activity and improves after resting is a classic symptom of peripheral artery disease (PAD). www.heart.org+1
-
Leg or foot numbness or weakness — reduced blood flow can produce these symptoms. Mayo Clinic
-
One foot or leg feels noticeably colder than the other — a possible sign of reduced circulation. www.heart.org
-
Changes in skin color — feet or legs may become unusually pale, bluish, or darker. www.heart.org+1
-
Sores on the feet or legs that heal very slowly — poor arterial blood flow can interfere with wound healing. www.heart.org
-
Reduced hair growth or slow-growing toenails — these can occur with PAD. Mayo Clinic
-
Sudden facial drooping, weakness/numbness on one side, or difficulty speaking — these can indicate a stroke or TIA and require emergency treatment. Mayo Clinic
-
Heart-attack symptoms — chest pressure/pain that spreads to the arm, shoulder, back, neck or jaw, particularly with sweating, nausea, dizziness, or shortness of breath, requires emergency medical attention. Mayo Clinic
🚨 When it’s an emergency
Call your local emergency service immediately for possible heart-attack or stroke symptoms. Don’t wait to see whether they disappear. Mayo Clinic+1
For recurring leg pain when walking, unexplained changes in your feet, or other circulation symptoms, arrange a medical evaluation. A clinician can assess circulation and, when PAD is suspected, may use an ankle-brachial index (ABI) and other vascular tests. www.heart.org
One important correction to many online “blocked artery” lists: swollen ankles by themselves are not a reliable indicator of blocked arteries. Swelling has many possible causes and should not automatically be attributed to poor arterial circulation.
