Another word used to describe a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. A heart attack is the death of a part of the heart caused by the loss of blood supply. The blood supply is usually gone due to a coronary artery being blocked by a blood clot. When a part of a heart artery breaks a blood clot forms around the piece. This blood clot can block the blood flow through the heart muscle. When the heart muscle needs oxygen it is called ischemia. When damage of a part of the heart muscle happens it’s called a heart attack. During a heart attack damage occurs depending on the size of the area blocked by the blood clot as well as the time between the actual heart attack and the treatment. Even though the heart may be hurt, the rest of the organs work with no problems. However, it will not pump as much blood as it used to in order to supply the same amount of blood to all of the parts of the body.
A heart attack occurs when an artery that supplies blood to the heart becomes blocked. The loss of oxygen and nutrients damage the heart's muscle tissue, causing the remaining healthy tissue to pump even harder to keep up.
Heart attack occurs when a blood clot suddenly and completely blocks a diseased coronary artery, resulting in the death of the heart muscle cells supplied by that artery. Coronary and Coronary Thrombosis 2 are terms that can refer to a heart attack. Another term, Acute Myocardial Infarction 2, means death of heart muscle due to an inadequate blood supply.
The heart is an organ that pumps blood from the body and maintains all the organs functioning to keep one alive; when one of the arteries that receive blood is blocked it can cause a heart attack or myocardial infarction (MI). “During a heart attack, the heart muscle (the myocardium) is damaged, and part of it die from lack of blood” (book, p. 429).
Heart muscle died as a results of myocardial infarction (MI) which the main coronary arteries was blocked, and large part of the heart muscle was affected due to cellular death from lack of blood flow and oxygen. Cell death is one of the most crucial events in the evolution of MI. A heart attack or MI is usually caused by a blood clot (thrombosis) that forms inside a coronary artery, or one of its branches, which suddenly blocks and stops the blood flowing to a part of the heart muscle. When the blood flow is interrupted necrosis occurs ( McCance & Huether, 2014).
While most people have heard of strokes, many don't know the importance of your carotid artery in causing a stroke. It's important for everyone to understand the signs of carotid artery disease and how to reduce the risk of it leading to a stroke.
LDL carries plaque which attaches to the walls of arteries and beings to build up. The plaque is a combination of cholesterol, fat, calcium and other substances. As it builds up over time, it hardens and the arteries become narrow, a condition called atherosclerosis. The blood cannot flow as freely and oxygen cannot get throughout the body as it should. If the plaque ruptures or breaks open, a blood clot can form. If the clot becomes large enough, blood flow is impaired or blocked completely. You may experience extreme pressure or pain in the chest called angina or possible pain in the shoulders, jaw, arms, back, or the discomfort associated with indigestion. This is a heart attack. Heart damage or even death may result if blood flow is not quickly restored. However, arteries leading to other parts of the body can have plaque buildup resulting in strokes, carotid artery disease, and peripheral artery disease. On the other hand, if the HDL is higher, the risk for heart disease is lower.
Atherosclerosis is a disease in which fatty materials and plaque buildup on the inner lining of arteries. Arteries are blood vessels which carry rich blood to the heart and throughout the body. They’re lined by the endothelium, a thin layer of cells. The endothelium keeps blood flowing by keeping the inside of arteries smooth. However, when Atherosclerosis starts due to high blood pressure, smoking, or high cholesterol, it damages the endothelium. Atherosclerosis tends to happen throughout the body and arises when people grow older. This disease is mainly due to the deposition of fatty materials i.e., cholesterol, calcium and other substances found in the blood. The buildup of fat then hardens causing narrowing of the arteries.

Many illness or diseases are known as silent killers because there are no signs or only vague signs of symptoms. These silent killers are deadly; in fact, they gradually consume a person in the early stages. One of those silent killers is High Blood Pressure also known as hypertension.
Myocardial Infarction (MI) is more commonly referred as the heart attack. This typically occurs due to an interruption, albeit partial to some part of the heart, which causes the cells in the heart to die and as a result sends
Hypertension is sometimes referred to as the “silent killer” because it frequently causes no symptoms. If your blood pressure is significantly elevated, you may develop:
