Clinical, experimental and pathologic studies strongly indicate that hypertension is a major factor in coronary heart disease, sudden death, stroke congestive heart failure and renal insufficiency. What are the 4 stages of atherosclerosis?
Atherosclerosis is the pathologic process by which cholesterol and calcium plaque accumulate within the arterial wall. … The working theory includes four steps:
- Endothelial cell injury. …
- Lipoprotein deposition. …
- Inflammatory reaction. …
- Smooth muscle cell cap formation.
What is the main cause of arteriosclerosis?
Atherosclerosis is 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 eating saturated fats. Does high blood pressure indicate clogged arteries?
Uncontrolled high blood pressure can result in hardening and thickening of your arteries, narrowing the channel through which blood can flow. High blood cholesterol levels. High levels of cholesterol in your blood can increase the risk of formation of plaque and atherosclerosis.
How does high blood pressure affect arteries?
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina. What are two of the hallmark signs of atherosclerosis?

Arteriosclerosis is a broader term for the condition in which the arteries narrow and harden, leading to poor circulation of blood throughout the body. Atherosclerosis is a specific kind of arteriosclerosis, but these terms are often used interchangeably.
What is the end stage of atherosclerosis?
If atherosclerosis slows the flow, chronic kidney disease can result. This can eventually lead to end-stage renal disease, or total kidney failure requiring dialysis.
What are the warning signs of clogged arteries?
Do clogged arteries cause any symptoms?
- Chest pain.
- Shortness of breath.
- Heart palpitations.
- Weakness or dizziness.
What are the symptoms of hypertensive heart disease?
Symptoms of hypertensive heart disease include:
- Chest pain.
- Shortness of breath.
- Sudden cardiac death.
What 3 foods cardiologists say to avoid?
How do you detect arteriosclerosis?
Your doctor will order blood tests to check your blood sugar and cholesterol levels. High levels of blood sugar and cholesterol raise your risk of atherosclerosis. A C-reactive protein (CRP) test also may be done to check for a protein linked to inflammation of the arteries. Electrocardiogram (ECG or EKG).
Does atherosclerosis show on ECG?
Doctors have an arsenal of diagnostic tests and tools they can access to confirm the presence of Atherosclerosis – these include an angiogram (Arteriogram), cholesterol tests, a chest x-ray, a CT (computed tomography) scan, Duplex scanning, an echocardiogram, an electrocardiogram (ECG or EKG), an exercise stress test ( …
Why is hypertension called the silent killer?
Often referred to as the “silent killer” because it may show no symptoms, high blood pressure puts you at an increased risk for heart disease, heart failure, and stroke, among other things.
How do u feel when your blood pressure is high?
In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs. Without symptoms, people with high blood pressure may go years without knowing they have the condition.
How high does your blood pressure have to be to have a stroke?
Sheps, M.D. A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure — a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher — can damage blood vessels.
What are the 4 stages of hypertension?
Doctors classify blood pressure into four categories: normal, prehypertension (mild), stage 1 (moderate) and stage 2 (severe). Treatment depends on which category your pressure consistently falls in when readings are taken.
What time of the day is blood pressure highest?
Usually, blood pressure starts to rise a few hours before you wake up. It continues to rise during the day, peaking in midday. Blood pressure normally drops in the late afternoon and evening. Blood pressure is normally lower at night while you’re sleeping.
Can high blood pressure cause blood clots in legs?
It is often discovered that when a person has a blood clot they also have high blood pressure. This leads many people to believe that blood clots which can cause conditions such as deep vein thrombosis (DVT) may also cause high blood pressure, but the reverse actually happens. High blood pressure causes blood clots.
What vitamin removes plaque from arteries?
Niacin, or Vitamin B3, is the best agent known to raise blood levels of HDL, which helps remove cholesterol deposits from the artery walls.
What dissolves artery plaque?
HDL is like a vacuum cleaner for cholesterol in the body. When it’s at healthy levels in your blood, it removes extra cholesterol and plaque buildup in your arteries and then sends it to your liver. Your liver expels it from your body. Ultimately, this helps reduce your risk of heart disease, heart attack, and stroke.
What foods should you avoid if you have atherosclerosis?
Your diet is an especially important factor in your risk for atherosclerosis, and heart disease generally. … Avoid or limit the following items:
- Fatty or marbled meats.
- Chicken wings.
- Hot dogs and sausages.
- Breaded or fried meat, fish, or poultry.
Can arteriosclerosis be reversed?
Completely reversing it isn’t possible yet. But taking a statin can reduce the risk of complications from atherosclerosis. It fights inflammation, which stabilizes the plaque. For this reason, statins are often key to treating atherosclerosis.
What are the symptoms of hardening of the arteries in the legs?
- Painful cramping in one or both of your hips, thighs or calf muscles after certain activities, such as walking or climbing stairs.
- Leg numbness or weakness.
- Coldness in your lower leg or foot, especially when compared with the other side.

Can you live a long life with atherosclerosis?
This can lead to severe health events such as heart attack and stroke. Living healthy with atherosclerosis is possible, though, and it’s important. Plaque, which is made up of fat, cholesterol and other substances, narrows the arteries and makes blood clots more likely to form.
What are 3 stages of the atherosclerosis?
The formation of the plaque can also be divided into three major stages namely 1) the fatty streak, which represents the initiation 2) plaque progression, which represents adaption and 3) plaque disruption, which represents the clinical complication of atherosclerosis.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
