The heart is a muscle about the size of a fist located behind the breastbone. It pumps blood through the body through two coronary arteries that encircle the heart. Coronary artery disease occurs when fatty deposits build up in the arteries and reduce blood flow, which can lead to chest pain, heart attacks, or heart failure. Risk factors for coronary artery disease include age, family history, smoking, high blood pressure, high cholesterol, obesity, and diabetes. Treatment depends on the severity of disease but may include lifestyle changes, medications, procedures like angioplasty to open blocked arteries, or bypass surgery.

Myocardial infarction is the medical name of a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety. Women are more likely to have atypical symptoms than men.
Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents, and bypass surgery.
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). It provides oxygen and nutrients to the heart muscle while removing carbon dioxide and other waste products. The coronary arteries branch off from the aorta and supply blood to the heart muscle. When these arteries become narrowed or blocked due to conditions like atherosclerosis, it can lead to coronary artery disease and potentially heart attacks.Coronary circulation is considered a type of systemic circulation because it is part of the larger circulatory system that supplies oxygenated blood to all the tissues and organs of the body, including the heart muscle itself. It is distinct from other types of circulation, such as pulmonary circulation, which involves the flow of blood between the heart and the lungs.
Coronary circulation branches off from the main systemic circulation. The coronary arteries, including the left coronary artery (which further divides into the left anterior descending artery and the circumflex artery) and the right coronary artery, are the main branches responsible for supplying blood to the heart muscle. These arteries then further divide into smaller branches and capillaries that penetrate the myocardium, ensuring oxygen and nutrients are delivered to all areas of the heart muscle.
Coronary circulation is vitally important because it supplies oxygen and nutrients to the heart muscle, allowing it to function properly. The heart is a muscular organ that continuously pumps blood throughout the body, including to its own tissues. Without adequate coronary circulation, the heart muscle can become deprived of oxygen, leading to tissue damage, dysfunction, and potentially life-threatening conditions such as heart attacks or myocardial infarctions. Therefore, maintaining healthy coronary circulation is crucial for overall heart health and optimal functioning of the cardiovascular system.
Coronary circulation is clinically important for several reasons:
1. **Coronary Artery Disease (CAD):** CAD is a condition where the coronary arteries become narrowed or blocked due to a buildup of plaque (atherosclerosis). This can restrict blood flow to the heart muscle, leading to chest pain (angina), heart attacks, and potentially life-threatening complications.
2. **Myocardial Infarction (Heart Attack):** When a coronary artery becomes completely blocked, it can cause a heart attack by depriving a portion of the heart muscle of oxygen and nutrients. Prompt medical intervention is critical to restore blood flow and prevent further damage to the heart.
3. **Diagnostic Tests:** Various diagnostic tests, such as coronary angiography and stress tests, are used to assess the function and integrity of the coronary circulation. These tests help diagnose coronary artery disease and guide treatment decisions.
4. **Interventions:** Procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) ..
CHAPTER 12: Cardiovascular Disease, Diabetes, and
Cancer
Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood
vessels. Cardiovascular disease includes coronary artery diseases (CAD) such
as angina and myocardial infarction (commonly known as a heart attack). Other
CVDs include stroke, heart failure, hypertensive heart disease, rheumatic heart
disease, cardiomyopathy, heart arrhythmia, congenital heart disease, valvular heart
disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic
disease, and venous thrombosis.
The underlying mechanisms vary depending on the disease. Coronary artery
disease, stroke, and peripheral artery disease involve atherosclerosis, which is the
narrowing of the inside of an artery due to the build up of plaque. This may be
caused by high blood pressure, smoking, diabetes, lack of exercise, obesity, high
blood cholesterol, poor diet, and excessive alcohol consumption, among others. High
blood pressure results in 13% of CVD deaths, while tobacco results in 9%, diabetes
6%, lack of exercise 6% and obesity 5%. Rheumatic heart disease may follow
untreated strep throat. It is estimated that 90% of CVD is preventable.
Coronary heart disease (CHD), also commonly referred to as just heart disease, is a
common term for the buildup of plaque in the heart’s arteries that could lead to
heart attack. But is there a difference between coronary heart disease and coronary
artery disease? The short answer is often no — health professionals frequently use
the terms interchangeably. However, coronary heart disease, or CHD, is actually a
result of coronary artery disease, or CAD. With coronary artery disease, plaque first
grows within the walls of the coronary arteries until the blood flow to the heart’s
muscle is limited. View an illustration of coronary arteries below:
Coronary Arteries
The Coronary Arteries are the blood vessels that supply blood to your heart. They
branch off of the aorta at its base. The right coronary artery, the left main coronary, the
left anterior descending, and the left circumflex artery, are the four major coronary
arteries. Blockage of these arteries is a common cause of angina, heart disease, heart
attacks and heart failure.
This restriction of the blood supply to the tissues is also called ischemia. It may be
chronic, narrowing of the coronary artery over time and limiting of the blood supply
to part of the muscle. Or it can be acute, resulting from a sudden rupture of a plaque
and formation of a thrombus or blood clot.
Anatomy of the Cardiovascular System
To fully understand Cardiovascular Diseases, it may be helpful to understand the
anatomy of the cardiovascular system. It includes the following:
o Heart: the pump, divided into four chambers (R/L atria, R/L ventricles)
o Arteries: large vessels carrying oxygen-rich blood away from heart; have
thick, muscular wall
o Arterioles: smaller arteries

The function of coronary circulation is to supply the heart muscle (myocardium) with oxygen, nutrients, and remove waste products to support its metabolic needs and maintain cardiac function. This circulation ensures that the heart itself receives the necessary oxygenated blood to pump effectively, despite the fact that it's constantly working. Without adequate coronary circulation, the heart muscle can become ischemic (lacking oxygen), leading to conditions like angina or myocardial infarction (heart attack).
Coronary circulation is a type of systemic circulation, as it involves the transport of oxygenated blood from the heart (left ventricle) to the tissues of the heart (myocardium) via the coronary arteries, and the return of deoxygenated blood from the myocardium to the right atrium of the heart through the coronary veins. It's a vital part of the overall circulatory system, specifically focusing on the needs of the heart tissue itself.
It seems like you're asking about the type of bench used in studying or observing coronary circulation. There isn't a specific "coronary circulation type bench" per se, but laboratories and medical facilities might have specialized benches or workstations equipped with materials and instruments for studying cardiovascular physiology, including models of the heart, vessels, and monitoring devices. These benches would be designed to facilitate experiments and resecoronary circulation.
Coronary artery disease (CAD) is a common type of heart disease and the most prevalent cause of heart attacks. It occurs when the coronary arteries, which supply oxygen-rich blood to the heart muscle, become narrowed or blocked due to the buildup of plaque (atherosclerosis). This narrowing restricts blood flow to the heart, leading to symptoms such as chest pain (angina), shortness of breath, and in severe cases, heart attack. Risk factors for coronary artery disease include high blood pressure, high cholesterol, smoking, diabetes, obesity, and a sedentary lifestyle. Treatment options include lifestyle changes, medications, procedures like angioplasty or stent placement, and in some cases, coronary artery bypass surgery.Maintaining a healthy lifestyle is essential for promoting good coronary circulation and overall heart health. Here are some key lifestyle habits to support coronary circulation:
1. **Regular Exercise:** Engage in aerobic exercises like walking, jogging, swimming, or cycling to promote cardiovascular fitness and improve blood flow throughout the body, including the coronary arteries.
2. **Healthy Diet:** Consume a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit intake of saturated and trans fats, cholesterol, sodium, and added sugars, which can contribute to plaque buildup in the arteries.
3. **Maintain a Healthy Weight:** Being overweight or obese can increase the risk of coronary artery disease. Aim for a healthy weight through a combination of regu .

The coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle (myocardium). These arteries originate from the base of the aorta, the main artery that carries oxygenated blood from the heart to the rest of the body. There are two main coronary arteries: the left coronary artery and the right coronary artery.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. •Is a muscle about the size of your fist
•Weighs approximately one pound
•Is located behind and slightly to the left of the breastbone
•Pumps about 5 quarts (4.7 liters) of blood every minute

4. The function of the heart is to circulate blood throughout the
body by:
•Pumping blood through the lungs removes carbon dioxide
and refreshes the blood with oxygen
•The oxygenated blood is pumped to the body to provide
oxygen and nutrients and to remove waste products.
•The coronary arteries are the blood vessels that supply blood
and oxygen to the heart muscle.
5. 2 coronary arteries branch from
the main aorta just above the
aortic valve. “No larger than
drinking straws, they divide and
encircle the heart to cover its
surface with a lacy network that
reminded physicians of a slightly
crooked crown (coronary comes
from the Latin
coronarius, belonging to a crown
or wreath). They carry out about
130 gallons of blood through the
heart muscle daily.” (Clark, 119)
Blood Supply To The Heart
6. Coronary artery disease is one of the most common and
serious effects of aging. Fatty deposits build up in blood
vessel walls and narrow the passageway for the
movement of blood. The resulting condition, called
atherosclerosis often leads to eventual blockage of the
coronary arteries and a “heart attack”.

8. “Cardiovascular disease claimed 39.4 percent of all
deaths or 1 of every 2.5 deaths in the United States in
2000. CVD was about 60 percent of “total mention
mortality.” This means that of over 2,400,000 deaths
from all causes, CVD was listed as a primary or
contributing cause on about 1,415,000 death certificates.”
(American Heart Disease)
9.
10. •Since 1900, CVD has been the No. 1 killer in the United States
every year but 1918.
•Nearly 2,600 Americans die of CVD each day, an average of 1
death every 33 seconds.
•CVD claims more lives each year than the next 5 leading causes of
death combined, which are cancer, chronic lower respiratory
diseases, accidents, diabetes mellitus, influenza and pneumonia.
•Almost 150,000 Americans killed by CVD each year are under age
65.
11. None: This is referred to as silent
ischemia. Blood to your heart may be
restricted due to CAD, but you don’t feel
any effects.
Chest pain: If your coronary arteries
can’t supply enough blood to meet the
oxygen demands of your heart, the result
may be chest pain called angina.
Shortness of breath: Some people may
not be aware they have CAD until they
develop symptoms of congestive heart
failure- extreme fatigue with
exertion, shortness of breath and
swelling in their feet and ankles.
Heart attack: Results when an artery to
your heart muscle becomes completely
blocked and the party of your heart
muscles fed by that artery dies.

does, occur in almost any artery in the body.
But in the heart it’s effects can be crucial. “The
body depends on a strong pumping heart to
circulate life-giving blood, and this includes to
the heart muscle itself. If the coronary arteries
become blocked, the cardiac muscle begins to
fail, and so the blood circulation
decreases, which includes the circulation to the
heart muscle itself.” (Thibodeau, 494)
17. •Blood tests: used to evaluate kidney and thyroid
function as well as to check cholesterol levels and
the presence of anemia.
•Chest X-ray: shows the size of your heart and
whether there is fluid build up around the heart and
lungs.
•Echocardiogram: shows a graphic outline of the
heart’s movement
•Ejection fraction (EF): determines how well your
heart pumps with each beat.
18. Many people are able to manage coronary artery
disease with lifestyle changes and medications.
Other people with severe coronary artery disease
may need angioplasty or surgery.
19.
20. Treatment (continued)
1) Stenting
• a stent is introduced into a blood vessel on a balloon
catheter and advanced into the blocked area of the artery
• the balloon is then inflated and causes the stent to expand
until it fits the inner wall of the vessel, conforming to
contours as needed
• the balloon is then deflated and drawn back
•The stent stays in place permanently, holding the vessel
open and improving the flow of blood.
21. Treatment (continued)
2) Angioplasty
• a balloon catheter is passed through the guiding catheter to the
area near the narrowing. A guide wire inside the balloon catheter is
then advanced through the artery until the tip is beyond the
narrowing.
• the angioplasty catheter is moved over the guide wire until the
balloon is within the narrowed segment.
• balloon is inflated, compressing the plaque against the artery wall
• once plaque has been compressed and the artery has been
sufficiently opened, the balloon catheter will be deflated and
removed.
22. Treatment (continued)
3) Bypass surgery
• healthy blood vessel is removed from leg, arm or chest
• blood vessel is used to create new blood flow path in your heart
• the “bypass graft” enables blood to reach your heart by flowing
around (bypassing)
the blocked portion
of the diseased
artery. The increased
blood flow reduces
angina and the risk
of heart attack.
23. •Get regular medical checkups.
•Control your blood pressure.
•Check your cholesterol.
•Don’t smoke.
•Exercise regularly.
•Maintain a healthy weight.
•Eat a heart-healthy diet.
•Manage stress.
