What is atherosclerosis? It is the hardening and narrowing of the arteries caused by cholesterol plaques lining the artery over time. This condition endangers blood flow and overall heart health.
Heart attacks, strokes, and peripheral vascular disease—collectively known as cardiovascular disease—are typically caused by arteriosclerosis or atherosclerotic cardiovascular disease. However, you can stop and reverse this process.
The arteries in your body are the blood vessels that transport blood from your heart to every part of your body. The endothelium, a thin layer of cells that lines the interior of your arteries, keeps them smooth and in good condition so that blood can flow through them.
Atherosclerosis is a very complex disease with numerous mechanisms and its common causes include:
As atherosclerosis worsens, plaque causes a lump on your arterial wall. When that mound grows large enough, it might cause a blockage. Your entire body is affected by that process, putting your risk of stroke and other illnesses in addition to heart disease.
Previously, atherosclerosis typically doesn’t manifest until you’re in your middle age years or later. But now, doctors see young adults having atherosclerosis due to their lifestyle. As the narrowing of your arteries worsens, atherosclerosis can cut off blood flow and create pain. Blockages can also suddenly rupture, which results in a blood clot at the location of the rupture in the artery.
Depending on which artery is narrowed or obstructed, symptoms may not appear until the artery is nearly closed or until a heart attack or stroke. Common signs and symptoms of atherosclerosis include: chest pain, palpitations, pain when walking (claudication), burning or prickling sensation, numbness, and abdominal pain.
Arrhythmia, an odd heartbeat, angina, or pain or pressure in the upper body, such as the chest, arms, neck, or jaw, are all signs that your coronary arteries need to be examined.
The arteries that provide blood to your brain might cause shortness of breath, numbness or weakness in your arms or legs, difficulty speaking or understanding others, drooping facial muscles, paralysis, severe headaches, and trouble seeing in one or both eyes. Leg pain when walking and numbness are signs that your arms, legs, and pelvis’ arteries are damaged.
Young people can develop atherosclerosis, and studies have shown that even teenagers can show symptoms.
The risk increases with age, most persons over 60 have some atherosclerosis, but most don’t have obvious symptoms. If you are in generally good condition at age 40, you have a 50% chance of developing significant atherosclerosis in your lifetime.
Over 90% of heart attacks are caused by these risk factors:
Because of improved lifestyles and therapies, atherosclerosis death rates have decreased by 25% over the last three decades.
The three primary types of cardiovascular disease are brought on by the plaques of atherosclerosis:
Once you have a blockage, it usually won’t go away. But you can slow or stop plaques with medicine and lifestyle changes. With vigorous therapy, plaque might even slightly contract.
Lifestyle modifications
By addressing the risk factors, such as a good diet, regular exercise, and quitting smoking, you can slow or stop atherosclerosis. While these adjustments won’t dissolve blockages, they have been shown to reduce the incidence of heart attacks and strokes.
Drugs for high cholesterol and high blood pressure will reduce and possibly even stop the development of atherosclerosis, lowering your risk of heart attack and stroke.
Your doctor may employ less invasive methods or more invasive ones to bypass atherosclerotic blockages:
Your physician will go over the risks associated with these procedures with you,
Atherosclerosis is the thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery.
Risk factors may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and poor diet.
Bits of plaque can break loose and cause blood clots that may lead to heart attack or stroke. There is currently no cure for atherosclerosis, but the condition can be slowed with certain drugs and dietary changes. Consult your doctor for the best treatment plan.
