Etiology Myocardial infarction occurs when the coronary arteries are blocked by a blood clot. It is commonly known as “heart attack”. The heart needs its own constant supply of oxygen and nutrients to work properly. Two coronary arteries delivery oxygenated blood to the heart, and if one of these two arteries fail or become blocked, then a portion of the heart will not acquire the necessary oxygen. This clot could be because of CAD (coronary artery disease), which happens when the inner walls of the coronary arteries thicken because of build up of cholesterol, fatty deposit, calcium among other elements that are carried in the blood (Boston Scientific, 2009).
The blocked portion of tissue in heart dies. Blockages can occur due to several factors. Coronary artery disease is the most prevalent cause. Coronary artery disease or atherosclerosis is due to plaque buildup and narrowing in the artery walls. These plaques are made from cholesterol and waste products.
A leading cause of a heart attack is Atherosclerosis- the buildup of plaque in the arter... ... middle of paper ... ...ons that will allow the individual to move forward in their fight to prevent heart attacks. Heart attacks are is a very dangerous disease. It’s caused by the buildup of plaque in the arteries, and the prevention of blood flow to essential organs. Cardiac arrest is often mistaken for heart attacks which put more people at risk, because ignorance is no defense for a heart attack. The symptoms are also not to be dealt with lightly since severe discomfort, heartburn, and lightheadedness can occur; on the flip side the side effects are even worse with severe damage to the heart and brain, coma, or even death as a result.
Diastolic dysfunction is the heart contracts normally, but the ventricle does not relax properly, reducing the amount of blood that can enter the heart and raise the blood pressure in the lungs. Heart failure is a progressive condition and can worsen over time. There are four stages of heart failure that have been classified by the AHA and ACC. Stage A are people that are at a high risk for developing heart failure. This includes people with high blood pressure, Diabetes, coronary artery disease and metabolic syndrome.
The liver is another organ that is affected by heart failure. “Heart failure can lead to a buildup of fluid that puts too much pressure on the liver. This fluid backup can lead to scarring, which makes it more difficult for your liver to function properly” ("Heart failure",
The most are caused by a blood clot that blocks one of the coronary arteries. Blood platelets sick to tears in the plaque and form a blood clot that blocks blood from following to the heart. A slow buildup of this plaque may almost block one of your coronary arties. Plaque is made up of cholesterol and other cells. Some major complications of myocardial infraction is arrhythmia, heart...
There is a very long list of things that can cause Congestive Heart Failure. Among that list are aging, being obese, Diabetes, and other diseases. One of the most common causes of Congestive Heart Failure is Hypertension, which is abnormally high blood pressure, causes the heart muscle to stress and pump against a lot of pressure. Having high blood pressure makes the heart work harder to pump blood, causing stiffness problems leading to muscle weakening, contributing to the development of Congestive Heart Failure. Congestive Heart Failure is also caused by heart attacks because heart attacks cause part of the heart muscle to be damaged and makes the heart pump less effectively.
Coronary Artery disease is when plaque builds up in the arteries around the heart, which can cause a heart attack. Coronary Artery disease is also one of the leading causes of death of in the United States. Many different medical places are trying to come up with a resolution to this disease, however there are only temporary fixes. The United States is spending a major amount of money to try and find a solution. There are many different symptoms include chest pressure or pain, shortness of breath, pain or discomfort in the arms or shoulder, pain or discomfort in the jaw, neck or back, and feeling weak, light headed, or nauseous.
When there is limited blood flow, oxygen supply is reduced. A blood clot will eventually form blocking the artery, stopping blood flow. With limited oxygen supply to the heart muscle a heart attack can happen or, if part of the brain is not receiving enough oxygen it will contribute to a stroke. Atherosclerosis is known to be categorized as a chronic disease which means it develops silently over time. It is the first stage of coronary heart disease.
Also the disease can clog arteries to the brain causing a serious stroke. Arrhythmia is where cardio vascular disease slows the beat of the heart. Arrhythmia also can speed the heart up to over 100 beats per minute. Stenosis can also occur. This is where the heart valves do not open up correctly.
