Atherosclerosis
Atherosclerosis is an intima-based lesion organized into a fibrous cap and an atheromatous (gruel-like) core and composed of SMCs, ECM, inflammatory cells, lipids, and necrotic debris.
Atherogenesis is driven by an interplay of inflammation and injury to vessel wall cells.
Atherosclerotic plaques accrue slowly over decades but may acutely cause symptoms due to rupture, thrombosis, hemorrhage, or embolization.
Risk factor recognition and reduction can reduce the incidence and severity of atherosclerosis-related disease.
Endothelial function can be improved after successful periodontal treatment
What is atherosclerosis
Atherosclerosis is a disease where plaque builds up in the arteries, limiting blood flow. Over time, plaque hardens and narrows the arteries. This can lead to serious problems like heart attack or stroke if it reduces blood flow too much. The plaque is made up of substances like fat, cholesterol, and calcium. Risk factors include smoking, high cholesterol, high blood pressure, and diabetes. Atherosclerosis can affect arteries throughout the body and lead to diseases like coronary heart disease, stroke, or peripheral arterial disease depending on where the blockages occur. Lifestyle changes and medication can help prevent atherosclerosis from worsening.
Atherosclerosis
Cardiovascular diseases involve the heart and blood vessels and are caused by multiple factors. Atherosclerosis is a type of arteriosclerosis where plaque builds up in the arteries, restricting blood flow. It develops over many years as a response to damage from high cholesterol, blood pressure, and smoking, which further aggravates and accelerates the hardening and narrowing of the arteries. Managing risk factors like controlling blood pressure, quitting smoking, cholesterol diet, exercise and medication can help prevent and treat atherosclerosis.
Cardiovascular Pathophysiology- Coronary Atherosclerosis and Arteriosclerosis
This document defines and compares arteriosclerosis and atherosclerosis. Arteriosclerosis is a hardening and loss of elasticity of the arteries, while atherosclerosis is a specific type caused by buildup of plaques in the artery walls. The document lists the main risk factors for atherosclerosis as smoking, high cholesterol, hypertension, and lifestyle factors. It describes the potential signs and symptoms depending on the affected artery, such as chest pain for coronary artery disease or leg pain for peripheral artery disease. The complications can include heart attack, stroke, or limb loss if left untreated. Prevention strategies include controlling blood pressure, managing diabetes, exercising, not smoking, and maintaining a healthy diet.
What is atherosclerosis
Atherosclerosis is a disease where plaque builds up in the arteries, limiting blood flow. Over time, plaque hardens and narrows arteries. This can lead to serious problems like heart attack or stroke if it reduces blood flow to organs and body parts. Atherosclerosis can affect any artery and cause diseases like coronary heart disease (the #1 killer in the US), carotid artery disease which can cause strokes, or peripheral arterial disease which affects arms and legs. Lifestyle changes and medication can help prevent and slow the progression of atherosclerosis.
Atherosclerosis by neha
This document provides information about atherosclerosis. It begins by introducing atherosclerosis as a pathological process in arteries that leads to coronary heart disease and stroke. It then describes how atherosclerosis develops from early childhood through adulthood, starting as fatty streaks and progressing to fibrous plaques that can rupture and cause blood clots. The document discusses the pathophysiology and causes of atherosclerosis in more detail and lists various symptoms like angina or leg pain that can occur depending on which arteries are affected.

Atheroscleros
Atherosclerosis is a condition where plaque builds up inside arteries due to a buildup of fatty materials such as cholesterol. Over time, plaque hardens and narrows the arteries, reducing blood flow. The buildup is caused by inflammation and an abnormal accumulation of substances inside the artery wall. Atherosclerosis most often affects arteries of the heart but can impact any artery. It is usually asymptomatic until an artery is severely blocked, which can lead to a heart attack or stroke. Diagnosis involves tests like angiograms, stress tests, and ultrasounds. Treatment focuses on lifestyle changes and medications to control risk factors and reduce plaque buildup.

Atherosclerosis is a condition where arteries become narrowed and hardened due to plaque buildup on their walls. Plaque is made of fat, cholesterol, calcium and other substances. It develops over many decades and causes endothelial dysfunction allowing LDL cholesterol to accumulate. Risk factors include high blood pressure, smoking, high cholesterol, diabetes and lack of exercise. Symptoms depend on the affected artery but may include chest pain, weakness, or difficulty breathing. Diagnosis involves physical exams, blood tests, ultrasounds and angiograms. Treatment focuses on lifestyle changes like diet and exercise as well as medications to lower cholesterol and blood pressure. Angioplasty and bypass surgery can be used for severe cases.

Peripheral vascular disease pvd
Peripheral vascular disease (PVD), also known as peripheral arterial disease (PAD), refers to diseases of the blood vessels outside the heart and brain. It develops when arteries become blocked by atherosclerosis, a buildup of cholesterol plaques in the artery walls. Over time, atherosclerosis can severely narrow arteries and limit blood flow, potentially leading to leg pain with walking, skin ulcers, gangrene, and amputation. Risk factors include smoking, diabetes, high blood pressure, high cholesterol, obesity, and physical inactivity. Treatment involves lifestyle changes, medication to reduce risk factors, supervised exercise to stimulate collateral blood vessels, and potentially angioplasty or bypass surgery for severe cases.

Atherosclerosis symptoms, causes, and treatment
Does your family history suggest that you are at a high risk of developing Atherosclerosis? Here is an article that will tell you about the causes, symptoms and prevention of this disease.
Information cd a
Cardiovascular disease refers to any disease affecting the heart or blood vessels. The most common causes are atherosclerosis and hypertension. Atherosclerosis involves plaque buildup within the artery walls due to damage from risk factors like high cholesterol, smoking, diabetes, and high blood pressure. This plaque buildup narrows the arteries and can lead to heart attacks or strokes if a plaque ruptures and blocks blood flow. Prevention focuses on lifestyle changes like a healthy diet, exercise, not smoking, moderating alcohol, and controlling conditions like high blood pressure and diabetes.

The cardiovascular system is transport system of body
The cardiovascular system consists of the blood, heart, arteries, and veins.
The system supplies nutrients to and remove waste products from various tissue of body.
The conveying media is liquid in form of blood which flows in close tubular system
Under healthy conditions, the cardiovascular, respiratory, and digestive systems are integrated:
The digestive system produces nutrients and the respiratory system furnishes oxygen, both of which circulate through the blood to various parts of the body.
In addition, the endocrine system affects the cardiovascular system by stimulating or depressing the rate of cardiovascular activity
Functions of cardiovascular system
Transport nutrients, hormones
Remove waste products
Gaseous exchange
Immunity
Blood vessels transport blood
Carries oxygen and carbon dioxide
Also carries nutrients and wastes

Blood vessels that carry blood away from the heart are called arteries.
They are the thickest blood vessels and they carry blood high in oxygen known as oxygenated blood (oxygen rich blood).
The smallest blood vessels are capillaries and they connect the arteries and veins.
This is where the exchange of nutrients and gases occurs.
Blood vessels that carry blood back to the heart are called veins.
They have one-way valves which prevent blood from flowing backwards.
They carry blood that is high in carbon dioxide known as deoxygenated blood (oxygen poor blood).
Coronary circulation the circulation of blood within the heart.
Pulmonary circulation – the flow of blood between the heart and lungs.
Systemic circulation – the flow of blood between the heart and the cells of the body.
DIRECTION OF BLOOD FLOW
Blood travels from the right ventricle of the heart to the lungs, where hemoglobin (one of the components of blood) saturates it with oxygen. From the lungs, oxygenated blood travels back to the left atrium of the heart, then to the left ventricle, and finally out to the rest of the body
The coronary arteries supply blood to the heart muscle, the myocardium.
The two principal coronary arteries branch off from the aorta the main artery that carries oxygenated blood from the heart.

The circulatory system transports nutrients, oxygen, water, and removes wastes throughout the body using the heart, blood, and blood vessels. The heart pumps blood through arteries and veins to all body cells via capillaries where oxygen and nutrients are exchanged for carbon dioxide and other wastes. Diseases can occur if this process is disrupted by issues like narrowed arteries or damaged heart muscles. The respiratory system takes in oxygen and removes carbon dioxide through breathing using the lungs, trachea, bronchi and diaphragm in a multi-step process. Pollution and other exposures can damage these systems and lead to diseases such as lung cancer, bronchitis or emphysema if not mitigated by a healthy lifestyle.

Atherosclerosis is a disease where plaque builds up inside arteries, restricting blood flow. It most commonly affects major arteries like the aorta, coronary, and cerebral arteries. Symptoms vary depending on which arteries are blocked, and can include chest pain, weakness, or loss of vision. Atherosclerosis is the leading cause of death in many countries. While the hardening of arteries cannot be reversed, lifestyle changes like a healthy diet, exercise, and not smoking can help prevent atherosclerosis from worsening. Current research focuses on developing new treatments using natural sources like plants, as well as promoting prevention through lifestyle modifications.

Atherosclerosis is a condition where plaque builds up inside the arteries, narrowing them. It occurs when fat, cholesterol, and other substances in the blood stick to damaged artery walls. Over time, plaque builds up, restricting blood flow. This increases the risk of blood clots forming and blocking arteries, which can lead to heart attacks or strokes if a clot dislodges. Symptoms depend on which arteries are affected but may include chest pain or weakness. Treatment focuses on lifestyle changes and medication to control risk factors and prevent complications.
Atherosclerosis
Arteriosclerosis occurs when arteries become thick and stiff due to a build-up of plaque, restricting blood flow. Atherosclerosis is a specific type involving a build-up of fats, cholesterol, and other substances in artery walls. It can affect arteries throughout the body, including those in the heart, legs, kidneys and brain. Symptoms vary depending on location but include chest pain, leg pain, fatigue and confusion. Risk factors include age, gender, family history, smoking, diabetes and high cholesterol. Treatment focuses on lifestyle changes and medications, while severe cases may require procedures like stenting or bypass surgery to improve blood flow.

It can affect arteries throughout the body, leading to coronary artery disease, carotid artery disease, peripheral artery disease, or kidney disease. Risk factors include age, gender, family history, and lifestyle factors like smoking and diet. Diagnosis involves tests like angiograms, stress tests, and blood work. Treatment focuses on lifestyle changes and medications, while advanced cases may require surgery to restore blood flow.
What causes atherosclerosis
Atherosclerosis is a disease where arteries become clogged with fat, cholesterol, and other substances which form plaque and harden the arteries. This reduces blood flow. It is caused when the layers of arteries become damaged and white blood cells try to repair them by taking in cholesterol, forming plaque. Over time plaque buildup narrows and hardens arteries. A closed circulatory system has advantages over an open one as it allows for incredible control over oxygen delivery and filtration of excess fluid through the lymphatic system. Lymphoma is a similar disease where blockages form in lymphatic vessels, causing swelling.
Heart attack plaque blood pressure
A myocardial infarction, or heart attack, occurs when blood flow to part of the heart is blocked, usually by a blood clot, and the heart muscle begins to die due to lack of oxygen. Coronary arteries can become blocked by plaques made of fat, cholesterol, and other substances that build up in the arteries. Rupture of a vulnerable plaque in a coronary artery often leads to a heart attack. Symptoms of a heart attack include chest pain and shortness of breath.
Coronary heart disease
This document provides an overview of coronary heart disease (CHD). It defines CHD as a disease involving the coronary arteries that supply the heart with blood. The main types of CHD discussed are arrhythmia, ischemic heart disease, angina pectoris, and myocardial infarction. Risk factors for CHD include smoking, diet, high blood pressure, stress, and physical inactivity. Diagnosis of CHD involves tests like electrocardiograms, stress tests, and angiograms. The document emphasizes prevention through a healthy lifestyle with a good diet, exercise, not smoking, and controlling conditions like high blood pressure.
Cardiovascular system
The cardiovascular system consists of arteries, capillaries and veins. Arteries carry oxygen-rich blood away from the heart to tissues. Capillaries allow for gas and nutrient exchange. Veins carry oxygen-depleted blood back to the heart. The pulmonary circuit carries deoxygenated blood to the lungs and oxygenated blood back to the heart. The systemic circuit pumps oxygenated blood to organs and deoxygenated blood back to the heart. Blood flow is driven by heart contractions and pressure differences between arteries, capillaries and veins.

This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

- 4. DEFINITIONS Atherosclerosis is hardening of a blood vessel from a buildup of plaque. Plaque is made of fatty deposits, cholesterol, and calcium. Plaque buildup causes the artery to narrow and harden. According (Hagler) Atherosclerosis It is characterized by intimal lesions called atheromas (also called Athermanous or atherosclerotic plaques), that protrude into vascular lumina. Plaque buildup can slow and even stop blood flow. According (Kwong)
