5 Critical Signs Your Arteries are Already Clogged

Summary

Dr. Quinn explains that arteries can narrow for years before a heart attack, and that early warning signs may be easy to overlook. He describes five possible clues:

1. Sudden loss or dimming of vision in one eye: A temporary “curtain” or dark area that clears may signal interrupted blood flow and warn of a stroke. Call emergency services for sudden, dramatic vision loss; don’t wait to see if it happens again. This differs from ordinary floaters or gradually worsening eyesight.

2. Pulsatile tinnitus: A new or persistent sound in one ear that beats in time with the heartbeat may reflect altered blood flow around the head or neck. Arrange a medical assessment. Seek immediate help if it occurs with weakness, speech problems, severe headache, dizziness, or vision problems.

3. Intermittent claudication: Predictable pain in the calf, thigh, or buttock that starts while walking, eases after stopping, and returns when walking again may indicate that narrowed arteries aren’t supplying enough blood to working leg muscles. Get it checked.

4. Persistent erectile dysfunction: Ongoing difficulty achieving or maintaining an erection can have many causes, including reduced blood flow. Consider discussing cardiovascular risk with a clinician and asking about blood pressure, cholesterol, blood sugar, and overall heart-disease risk. Treating the symptom alone may not address its cause.

5. Angina: Pressure, heaviness, or squeezing in the chest—or discomfort in the arm, jaw, neck, back, or upper abdomen—during exertion that improves with rest may mean the heart isn’t getting enough blood. If chest discomfort is severe, worsening, or doesn’t settle, call emergency services.

David’s story illustrates that a heart attack may not truly come “out of nowhere”: he had previously noticed chest tightness during exertion but hadn’t acted on it. The central advice is to take recurring or sudden warning signs seriously and seek appropriate medical help.
