The Impact of Atherosclerosis on Cardiovascular Health
Atherosclerosis is a contraction of the arteries caused by the growth of plaque. Your arteries are the blood vessels that carry pure oxygen and minerals from your heart to the rest of your body. According to experts, atherosclerosis is a condition that develops when plaque forms on the interior walls of arteries. Your plaque is a viscous substance made of fat, cholesterol, calcium, and other substances. When you develop plaque, the arteries become hard and narrow.
How can the hardening of the arteries affect my body?
Atherosclerosis may start in childhood, and it gets hard over time. Hardening of the arteries can cause fatal problems. Your blocked arteries may not deliver enough blood, oxygen, and nutrients to the rest of the body. Your blockage can lead to tissue death or infection in the arms and legs. Your plaque can break free and get stuck somewhere in the body, causing damage. Your blood clot can form in a narrow artery. Plaque can travel through the blood artery.

Atherosclerosis can lead to fatal health problems and medical emergencies, including:
- Blood clots.
- Carotid artery disease.
- Chronic kidney disease.
- Coronary artery disease.
- Heart attack.
- Peripheral artery disease.
- Stroke.
- Death.
Possible risk factors for atherosclerosis include:
- Diabetes mellitus or high blood sugar
- Family history of premature cardiovascular disease.
- High BP (hypertension).
- High cholesterol.
- Absence of physical activity.
- Male
- High Obesity.
- Older age
- Smoking
- An unhealthy diet high in saturated
Although scientists know the risk factors for coronary artery disease (CAD), they do not fully understand why some people develop the condition while others do not. Patients often believe that atherosclerosis begins due to damage to the endothelium, which is the inner lining of the artery. Risk factors such as smoking, high cholesterol, high blood pressure, and high blood glucose can contribute to the development of CAD. When damage occurs, plaque accumulates in the affected area, which may trigger the body to produce more substances. As a result, the arteries become progressively narrowed, and blood flow decreases over time.

How is atherosclerosis diagnosed?
To determine whether you have atherosclerosis, your cardiologist will start with:
- Entire family medical history.
- Personal medical history.
- Physical exam, listening with a stethoscope for weak or absent pulse or an abnormal sound in your arteries called a bruit.
- Various blood tests can measure the fat, cholesterol, sugar, and protein in your blood.
- Your cardiologist will conduct angiography, a test that uses special X-rays to locate and measure blockages. A contrast dye is injected into the arteries to help the barriers show on the X-rays. Your cardiologist performs through a catheter inserted into an artery, usually in the groin or arm.
- Your cardiologist may work for the ankle/brachial index. It compares the blood pressure in your ankle to the stress in your arm to measure blood flow.
- Your cardiologist will take many chest X-rays, which take pictures inside your chest.
- Your cardiologist will perform a CT scan. It takes pictures inside the body and can show the hardening and narrowing of large arteries.
- Your cardiologist will go for an echocardiogram (echo). It is a painless test that takes pictures of the heart’s valves, and chambers and measures pumping action.
- Your cardiologist will conduct an electrocardiogram (EKG). It is a painless test which measures the heart’s electrical activity, rate, and rhythm.
- Your cardiologist will go for an exercise stress test. It measures heart function while you are physically active.
How is atherosclerosis treated?
Treatment for atherosclerosis may comprise lifestyle changes, medications, and surgical procedures.
The aims of the treatment are to:
- Your doctor reduces the risk of blood clots.
- Your cardiologist offers healthier choices to prevent heart or vascular conditions.
- Your doctor prevents atherosclerosis-related diseases and complications.
- Your cardiologist relieves the symptoms.
- Your doctor will slow plaque buildup.
- Widening or bypassing clogged or blocked arteries.
Your cardiologist may also prescribe medications to:
- Control BP.
- Lower cholesterol.
- Manage blood sugar levels.
- Prevent blood clots.
Some patients with advanced atherosclerosis might require surgical procedures, such as:
- Coronary angioplasty is also called percutaneous coronary intervention. It opens narrow or blocked coronary (heart) arteries.
- Your cardiologist performed a catheter inserted into a groin artery (cardiac catheterization).
- Your cardiac surgeon may place a stent (small tube) in the blood artery to prop it open.
- Coronary artery bypass surgery bypasses (goes around) a narrowed artery by using arteries or veins from other parts of your body.
- Bypass surgery averts blood from a clogged leg artery and improves blood flow to the leg.
- Carotid endarterectomy is a procedure that removes plaque from the arteries in the neck to reduce the risk of a stroke.
How can I restrict atherosclerosis?
It may not be possible to eliminate atherosclerosis but specific steps you can take to reduce your risk and minimize the impact of the disease. Some ways to do this include:
- You can eat a healthy diet low in saturated fats and sugar.
- You have to exercise regularly with no excuse
- You will maintain a healthy weight.
- You can manage all health conditions, especially diabetes, high BP, and high cholesterol.
- You can quit smoking
- You can have an annual checkup with your cardiologist.

FAQs about atherosclerosis:
Q: What is atherosclerosis, and why is it dangerous?
A: Atherosclerosis is a condition where plaque, a buildup of fatty material, cholesterol, and other substances, accumulates inside your arteries. This atherosclerosis narrows the arteries, restricting blood flow to your organs. Reduced blood flow can lead to complications like heart attack, stroke, and even leg amputation.
Q: I don't have any symptoms. Does it mean I don't have atherosclerosis?
A: Atherosclerosis often develops silently for many years. You might not experience symptoms until the plaque buildup significantly narrows your arteries or a piece of plaque breaks off and forms a clot. That's why regular checkups with your doctor are crucial for early detection and prevention.
Q: What are some things I can do to prevent atherosclerosis?
A: Many lifestyle changes can significantly reduce your risk of atherosclerosis. Eating a heart-healthy diet low in saturated fats and cholesterol, exercising regularly, maintaining a healthy weight, and managing stress are all vital steps. If you smoke, quitting is one of the best things you can do for your cardiovascular health.
Q: How do doctors diagnose atherosclerosis?
A: Doctors can use various methods to diagnose atherosclerosis. These may include blood tests to check your cholesterol levels, blood pressure monitoring, imaging tests like ultrasounds or CT scans to visualize your arteries, and an ankle-brachial index (ABI) test to assess blood flow in your legs.
Q: If I am diagnosed with atherosclerosis, can it be treated?
A: Absolutely. While there is no cure for atherosclerosis, treatment focuses on managing your risk factors, slowing disease progression, and preventing complications. This step might involve medication to lower cholesterol and blood pressure, lifestyle changes, and procedures to open blocked arteries.
Q: Who is at risk for atherosclerosis?
A: Atherosclerosis can influence anyone, but some people are more likely to acquire it than others.
Recent advancements in combating atherosclerosis have led to innovative techniques and herbal remedies. Researchers are exploring novel approaches, such as targeted drug therapies, to halt the progression of plaque buildup in arteries. Additionally, there's growing interest in herbal remedies like garlic, turmeric, and green tea, which have shown promising results in reducing inflammation and improving cardiovascular health. These developments offer new avenues for managing atherosclerosis and promoting heart health, underscoring the importance of ongoing research and holistic approaches to tackling this prevalent condition.
