Myocardial Infarction
Introduction
A myocardial infarction or heart attack, is the death or damage of part of the heart muscle because the supply of blood to the heart is severely reduce or stopped. Myocardial infarction (MI) is the leading cause of death in the United States. More than 1.5 million Americans suffer a myocardial infarction every year, and nearly half a million die, according to the American Heart Association. Most myocardial infarctions are the end result of years of silent, undetected, progressive coronary artery disease. Causes:
One of the most common causes of heart attack is coronary artery disease, where coronary arteries overcome hardened and narrowed to atherosclerosis. Atherosclerosis refers to the accumulation of
The heart is an organ that is controlled by an electrical system, which is the one that makes you contract in each beat. If a heart attack injury causes an alteration in this circuit, there are so-called cardiac arrhythmias, where the heart does not contract in a rhythmic way, which causes serious consequences at a general level.
 Mechanical insufficiency due to the large amount of area damaged by the infarction, the heart muscle loses part of its function and does not send enough blood to the rest of the body.
 Other Complications as a consequence of the infarction, the following situations can also occur, albeit less frequently: cardiac rupture, ventricular aneurysm (dilation of a zone of the heart that causes a worse functioning of the heart), pulmonary thromboembolism (a blood clot forms Blood that travels to the lung, where it prevents the arrival of blood flow) or pericarditis (inflammation of the heart cover) (2016).
Risk Factors:
 Smoking is one of the most important risk factors for cardiovascular diseases: myocardial infarction, hypertension, stroke, arteritis of the lower limbs, impotence and thrombosis. These cardiovascular diseases are aggravated in
 Erection problems the formation of a plaque of atheroma in the penile arteries can provoke impotence, also called erectile dysfunction.
 Sex
I. Men are more affected than women.
II. The cardiovascular risk of women reaches that of men after menopause.
 The alcohol consumption in excess represents a risk factor for myocardial infarction and cardiovascular diseases (CCM, 2017).
Prognosis
Experienced emergency care personnel confirm the diagnosis of MI, by taking a thorough history, checking heart rate and blood pressure, performing an electrocardiogram, and drawing a blood sample. The electrocardiogram shows which of the coronary arteries is blocked. The blood test detects the leak of enzymes or other biochemical markers from damaged cells in the heart muscle. In clinical practice, timely treatment is based on the patient history, physical examination, and ECG findings.

    There are four different categories of treatment: lifestyle changes, surgical procedures, non-surgical procedures, and medications. Lifestyle changes include having a healthy diet; increasing physical activity; eliminating cigarettes, alcoholic beverages, and illicit drugs; and getting enough rest and sleep; losing excess weight. These lifestyle changes are to lower the patient’s blood pressure, cholesterol, and reducing any other future medical conditions. There are also surgical options to help cure, prevent, or control cardiomyopathy. Surgical method include a septal myectomy, surgically implanted devices, and a heart transplant. A septal myectomy is used to specifically treat hypertrophy cardiomyopathy which is where the heart muscle cells enlarge and cause the walls of the ventricles to thicken. The thickening of the walls may not affect the size of the ventricles but instead may affect the blood flow out of the ventricle. Usually along with the ventricles swelling, the septum in between the ventricles can become enlarged and block the blood flow causing a heart attack. When medication is not working well to treat hypertrophic cardiomyopathy, a surgeon will open the chest cavity and remove part of the septum that is blocking blood flow. Surgically implanted devices include a pacemaker, a cardiac resynchronization therapy device, a left ventricular assist device, and an implantable

    The term acute myocardial infarction is used when talking about myocardial necrosis in a setting consistent with myocardial ischemia (Steg, et al., 2012). Acute myocardial infarctions are the major cause of disability and death worldwide. Myocardial infarctions can be one of the first signs of acute coronary syndrome and they can also occur repeatedly in patients that have an ongoing coronary artery disease (Thygesen, et al., 2012).

    Atherosclerosis begins when the inner wall of the artery becomes damaged and cholesterol and fatty plaques begin to lodge in the arteries. Damage to the endothelial wall inside the artery can be caused by hypertension, hyperlipidemia, and hyperglycemia (“Subclinical Atherosclerosis..” 443). When this happens, the immune system responds by sending monocytes to the damaged area. The monocytes turn into macrophages; their job is to eat up the excess cholesterol and unblock the artery. The macrophages are unable to digest all of the cholesterol, and as a result turn in to foam cells. When many macrophages are turned into foam cells, plaque results, and protrudes into the arterial wall, restricting blood flow and raising blood pressure (“Atherosclerosis Growth Process.” 8). If the plaque becomes too large it may break, releasing plaque into the blood. This can cause a great reduction in blood flow or a clot, resulting in stroke or myocardial infarction (“Stroke Risk.” 3).

    The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.

    The preliminary step in myocardial infarction is atherosclerosis. Atherosclerosis does not occur abruptly, it is a gradual and dynamic inflammatory disease which causes the narrowing of lumen due to the deposition of lipid and foam cells. The formation of fatty streak; which will eventually become a plaque causes the vessel lumen to diminish. The plaque will become unstable, rupture and eventually lead to the event of plaque disruption.

    In order to know what myocardial infarction is, it is important to know when to diagnose the condition and to do it as soon as possible. It is vital to be able to know the sign and symptoms for a myocardial infarction and how to treat them to prevent any further damage to the myocardium. Since damage can occur to the myocardium, heart muscle, one of the goals is to save as much of the heart muscle as possible through procedures to be able to open up the blood vessels to make sure blood is traveling to the heart and heart muscles like a percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery.

    Alcoholism accounts for more than 15% of health care costs in the elderly. It is associated with an estimated 100,000 deaths per year in the United States. Alcohol consumption can produce both benefits and risks. In terms of benefits, men who drink two to six alcoholic beverages per week have decreased mortality rates and lower cardiovascular disease when compared with abstainers. On the negative side, two studies of 300,000 men demonstrated increased mortality among those consuming more than 2 to 3 drinks daily. Women, are more affected by less alcohol than men, perhaps because they have a lower blood volume, and so it’s distribution and decreased activity for gastric alcohol dehydrogenase are increased.

    One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.

    Alcohol consumption will need to be discontinued, especially if this is a cause. Moderate exercise should be encouraged within the limitations of the patient (Bennett). Medical treatment is generally aimed at relieving symptoms of heart failure and improving cardiac output. Patients are often given medications such as ACE inhibitors and Beta-blockers. Antiarrhythmic drugs, implantable defibrillators, and pacemakers are other treatments used for dilated cardiomyopathy patients. Anticoagulants are also an important treatment for dilated cardiomyopathy patients due to the increased risk of developing thrombus from poor systolic function, atrial fibrillation, and poor circulatory flow. Cardiac transplantation is another treatment option but heart donors are very limited (Lily).
