Myocardial Infarction

Heart attacks most often occur as an outcome of coronary artery disease or also known as coronary heart disease (CHD). Coronary heart disease is a condition where plaque (waxy substance) builds up within the coronary arteries. These arteries deliver oxygen-rich blood to your heart. The plaque is made up of cholesterol and other cells. A heart attack can happen when there is a tear in the plaque, this triggers blood platelets and other substances start to form a blood clot at the site that blocks blood from being able to flow to the heart.

If this problem is not treated right away, the portion of the heart fed by the artery will begin to die. Scar tissue will form on what was once health heart tissue. The heart damage may not be noticeable, or it may cause severe or long-lasting problems. (National Heart, Lung, and Blood Institute) Another cause of heart attacks is due to a severe coronary artery spasm, this is this least common cause. Coronary artery spasms are brief temporary tightening or contraction of the muscles in the artery wall.

Prevention and Treatments of Coronary Heart Disease Coronary heart disease is caused by the narrowing of the coronary arteries, which feed the heart. All muscles need a constant supply of oxygen and nutrients, therefore so does the heart since it to is a muscle. The heart gets these nutrients and oxygen by the blood carried to it by the coronary arteries. However, when the coronary arteries get clogged by fat deposits and cholesterol, the coronary arteries become narrower, this process is called atherosclerosis, and therefore not enough blood gets supplied to the heart and results in coronary heart disease (CHD). There are different forms of CHD which can occur.

Overall cardiac output is the amount of blood that the heart pumps each minute. Congestive heart failure represents the end product of the many conditions that reduce the thrusting ability of the heart. Congestive heart failure is not a detailed disease but a illness that is measured by the inability of the heart to pump blood adequate with the metabolic needs of the body. Heart failure is accompanied by overcrowding of the body tissues. For instance, heart failure may be shown as an acute condition as in pulmonary edema or as a chronic condition as in congestive heart

Ischemia (reduced blood flow to tissues) to the tissue the coronary artery supplies with become damaged and, with long enough occlusion, die (American Heart Association, 2012). Signs and Symptoms Most myocardial infarctions begin with mild pain or discomfort in the chest. Those suffering often aren't sure what's wrong and wait too long before getting help (American Heart Association, 2012).

The damage in a transmural MI will generally extend much deeper into the muscle tissue (Heuther and McCance, 2012).

here are many causes of cardiomegaly but the most common cause is the blockage of blood supply to the heart. This often results due to coronary artery disease and high blood pressure. Other causes of an enlarged heart are viral infection, abnormal heart valve, peripartum cardiomyopathy, kidney disease, HIV infection, severe anemia, thyroid disorders, previous myocardial infarction, ... ... middle of paper ... ...sing sudden death.

When the body builds up with fluids, it becomes congested. Many conditions can cause heart failure, and they are Coronary artery disease, Heart attack, Cardiomyopathy, and conditions that overwork the heart. Systolic and Diastolic are the two types of Heart Failure. Systolic dysfunction occurs when the heart muscle doesn't contract with enough force, which means there is less oxygen-rich blood that is pumped throughout the body. 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.

If you have any kind of disease you may eventually develop Congestive Heart Failure due to the large amount of causes. Although there are many symptoms, no one should use just one in self diagnosis, because having just one or two of the symptoms does not mean you have the disease. If you are concerned about your health and thing you may have Congestive Heart Failure, call a doctor and get treated as soon as possible.

Angina is a feeling that can range from numbness or pressure to severe pain in your chest, arms, jaw, throat or upper back. Coronary artery disease (CAD) is atherosclerosis, or hardening of the artery that provides vital oxygen and nutrients to the heart. Diagnosis of Heart Disease Up to half of patients have no cardiac diagnoses, and even many of those with coronary disease are at low risk for early events ( 1mm, ischemic elevation, T wave inversions or new LBBB) may have much higher event rates, many hospitals have developed chest pain observation units to provide a longer period of observation and immediate testing in patients determined to be at low risk in order to improve the triage process. In many cases those who have no electrocardiography changes or cardiac enzyme elevations undergo treadmill exercise test or imaging procedures to exclude ischemia at the end of a 6-24 hours period and are discharged directly from the emergency department if theses test are negative. See www.cmdtlinks.com Diagnosis of Heart Disease The diagnosis of this problem is based upon clinical history and physical exam.

Causes of blockage range from congenital tissue strands within or over the arteries to spasms of the muscular coat of the arteries themselves. By far the most common cause, however, is the deposition of plaques of cholesterol, platelets and other substances within the arterial walls. Sometimes the buildup is very gradual, but in other cases the buildup is suddenly increased as a chunk of matter breaks off and suddenly blocks the already narrowed opening. Certain factors seem to favor the buildup of these plaques. A strong family history of heart attacks is a definite risk factor, reflecting some metabolic derangement in either cholesterol handling or some other factor.
