Symptoms of Clogged Arteries: Coronary and Peripheral Artery Disease
Clogged arteries, also known as atherosclerosis, can affect different parts of the body, most commonly the heart (coronary artery disease) and the legs (peripheral arterial disease). The symptoms depend on which arteries are affected and how severe the blockage is.
Coronary Artery Disease (CAD) Symptoms
The most common symptom of clogged arteries in the heart is chest pain or discomfort, often called angina. This pain may feel like pressure, squeezing, or fullness in the chest and can sometimes spread to the arms, neck, jaw, or back. Other symptoms include shortness of breath, especially during physical activity, and in severe cases, a heart attack may occur if the blood flow is completely blocked. Some people may also experience arrhythmias (irregular heartbeats) or heart failure as complications of CAD. These symptoms are more likely in people with risk factors such as high blood pressure, high cholesterol, smoking, diabetes, and a family history of heart disease Dhakal,2024Kaur2023Dayana2023.
Peripheral Arterial Disease (PAD) and Peripheral Vascular Disease (PVD) Symptoms
When arteries in the legs are clogged, the most common symptom is pain or cramping in the legs during walking or exercise, which goes away with rest. This is known as intermittent claudication. As the disease progresses, people may experience pain even at rest, numbness, weakness, or coldness in the lower leg or foot. In severe cases, poor blood flow can lead to sores, infections, or even tissue death, which may require amputation. Many people with PAD or PVD may not have symptoms in the early stages, but as the blockage worsens, symptoms become more noticeable. Risk factors for PAD are similar to those for CAD and include smoking, diabetes, high blood pressure, and high cholesterol Darwis2020M2024.
Overlapping and Asymptomatic Cases
It is important to note that about half of people with peripheral vascular disease may not have any symptoms, especially in the early stages. Similarly, some people with coronary artery disease may not notice symptoms until the blockage is severe or a heart attack occurs. This is why regular check-ups and attention to risk factors are important for early detection and prevention Darwis2020M2024.
Conclusion
Clogged arteries can cause a range of symptoms depending on the location and severity of the blockage. Chest pain and shortness of breath are common with coronary artery disease, while leg pain during activity is typical for peripheral arterial disease. However, many people may not have symptoms until the disease is advanced. Recognizing risk factors and early warning signs is key to preventing serious complications like heart attacks, strokes, or limb loss Dhakal,2024Darwis2020Kaur2023+2 MORE.
