Your arteries may be clogging if you feel or hear these 5 signs, often long before a heart attack

Clogged arteries don’t necessarily stay silent until a heart attack or stroke happens. Atherosclerosis — plaque buildup in the arteries — often sends specific signals years in advance, some well-known and some showing up in places most people wouldn’t think to connect to their arteries at all. Catching these early matters, because the underlying disease process can take decades to build before symptoms appear. (Based on the insights of Dr. Mitch Rice)

This classic sign, called claudication, is one of the most well-documented physical signs of arterial disease outside the heart. It typically feels like a cramping, aching, or heavy sensation in the calf, thigh, or hip that reliably appears after walking a certain distance and eases with rest. This happens because narrowed leg arteries can’t deliver enough oxygenated blood to keep up with working muscle during activity — essentially the same mechanism that causes chest pain during exertion when coronary arteries are narrowed, just occurring in the legs. This is known as peripheral artery disease, and it shares the same underlying cause — plaque buildup, or atherosclerosis — as coronary artery disease, just in a different location. Research has consistently found that people with peripheral artery disease carry a significantly elevated risk of heart attack and stroke, even if they’ve never experienced chest pain. A consistent pattern of leg discomfort with walking that eases with rest is worth bringing up with your doctor.

This is a sign most people wouldn’t think to connect to arterial health. The arteries supplying blood to the lower back and spine are among the earliest in the body to accumulate plaque, and reduced blood flow to this region can contribute to disc problems and pinched nerve issues. Research examining chronic back pain — the single most commonly reported type of pain in the United States — has found that people with chronic back pain are more likely to have blockages in these lumbar arteries compared to people without chronic back pain. This doesn’t mean every case of chronic back pain is vascular in origin — most back pain is mechanical or musculoskeletal. But persistent, unexplained chronic back pain, especially alongside other signs on this list or other cardiovascular risk factors, is worth considering as a potential vascular signal rather than automatically attributing to wear and tear.

This is a sign your doctor can detect, but one that isn’t always checked during a routine physical. When plaque narrows the carotid arteries in the neck, it can create a distinct whooshing sound, called a bruit, audible through a stethoscope placed on the neck. Carotid artery narrowing frequently produces no symptoms in its early stages, which is exactly why many people don’t discover it until they experience a transient ischemic attack (“mini stroke”) or a full stroke. If you have high blood pressure, high cholesterol, or a family history of stroke, it’s reasonable to specifically ask your doctor whether they’ve listened for a carotid bruit during your next physical exam.

This sign applies specifically to men, but it’s backed by some of the most reliable research on this list. The arteries supplying blood to the penis are smaller in diameter than the coronary arteries feeding the heart, so plaque buildup tends to restrict blood flow here first — often years before the same process becomes significant enough to cause chest pain or a cardiac event. Medical researchers now recognize erectile dysfunction as a legitimate early warning sign for atherosclerosis risk. A cost-analysis study found that systematically screening men who present with erectile dysfunction for cardiovascular risk factors could prevent roughly 1.1 million cardiovascular events (heart attacks and strokes) over a 20-year period, simply by catching arterial narrowing in these smaller vessels before it progresses to larger ones. If you’re experiencing this and attributing it solely to aging, it’s worth asking your doctor directly whether further cardiovascular risk evaluation makes sense.

This is distinct from ordinary tinnitus (a constant buzzing or ringing). Pulsatile tinnitus is a rhythmic whooshing, pulsing, or thumping sound — audible only to you — that beats in sync with your own heartbeat. Plaque buildup creates a rougher surface for blood to travel over, and as blood moves across that rough surface, it creates turbulence rather than smooth (laminar) flow — turbulence your ear can pick up given how close major blood vessels run to the inner ear. Research has identified pulsatile tinnitus as one of the earlier, non-specific signs that can appear with narrowing of the carotid artery specifically. If you notice a whooshing or thumping sound in one or both ears that rises and falls with your heartbeat, bring this up with a healthcare provider.

Every sign on this list shares something most people don’t realize: atherosclerosis doesn’t begin the moment symptoms appear. Autopsy and imaging research on young people has found that plaque formation can begin as early as childhood or the teenage years, with measurable arterial narrowing already present in a meaningful share of people by their early 20s. These five warning signs aren’t the beginning of the disease process — they’re the point at which it has finally progressed enough to cause noticeable symptoms, after what may have been decades of silent progression. The encouraging part is that these signs generally appear months to years before a serious cardiovascular event, which means there’s real time to act.

None of these five signs, taken alone, guarantees an arterial problem — each has other, more common explanations. But if you experience any of them, especially alongside other cardiovascular risk factors like high cholesterol, high blood pressure, a family history of heart or vascular disease, or blood sugar issues, it’s worth taking seriously and discussing with your doctor.

No. Each of these signs has other, more common explanations — most back pain is musculoskeletal, for example, and tinnitus has many causes unrelated to arteries. They’re worth taking seriously as a prompt to talk to your doctor, especially alongside other cardiovascular risk factors, not as a standalone diagnosis.

How is pulsatile tinnitus different from regular tinnitus? Regular tinnitus is typically a constant buzzing, ringing, or hissing sound. Pulsatile tinnitus specifically rises and falls in sync with your own heartbeat — a rhythmic whooshing or thumping rather than a steady tone. That rhythmic quality is the key distinguishing feature.

The arteries supplying blood flow for erectile function are smaller in diameter than coronary arteries, so plaque tends to narrow them first — sometimes years before the same buildup becomes significant enough to affect the heart. This makes erectile dysfunction a potential early warning sign worth discussing with a doctor, not just an isolated issue.

Much earlier than most people assume. Autopsy and imaging research has found that plaque formation can begin as early as childhood or the teenage years, with measurable arterial changes already present in a meaningful share of people by their early 20s — long before any of the signs described here would typically appear.
