Myocardial Infarction: Case Study Causes, Incidence, and Risk Factors for Myocardial Infarction Myocardial infarction (MI) is an impairment of heart functioning characterized by the diminished blood supply to cardiac muscles following myocardial ischemia (Wong et al., ). It occurs within 24 hours after infarction or between the third and fifth day, has an incidence of to % and is more common in an extensive myocardial infarction, in the elderly, women and hypertensive lxevyings.cf: Wilma Noia Ribeiro, Alice Tatsuko Yamada, Luiz Alberto Benvenuti. Acute Myocardial Infarction. Case Presentation. A year-old male complaining of chest pain is brought to the emergency room by ambulance. The pain began six hours ago and has become more severe over the past hour prompting him to call emergency services. He describes the pain as retro-sternal, pressure-like, and non-radiating.

Schoolwires, case study of myocardial infarction, Inc. Description: Myocardial infarction heart attack is the leading cause of death in the United States. It is estimated that one in every five deaths in the US is due to a heart attack.

Approximately one million patients are admitted to hospitals each year due to heart attacks. Send to Colleague. Contributing Organization: Schoolwires, Inc. See more. At around a. Alarmed when he told her of the pain in his chest, neck and arm, she called Within 12 minutes, emergency response team personnel EMTs were on the scene. Case Questions 1. What symptoms did Jason exhibit? If you were an emergency medical technician treating a suspected myocardial infarction heart attackwhat would you do for initial assessment of the patient?

What initial treatment would you give the patient? He was 80 lbs. He was also a moderate cigarette smoker, case study of myocardial infarction. According to his wife, he exercised very little and paid virtually no attention to diet, often eating fast food, as well as eating late at night. His father died at age 56 from heart disease. Case Question 4.

Summarize the lifestyle risks of the patient. Find and view the slide show on the structure of a preserved heart. This is interesting to view but in depth. You will not be tested on this! Study the structure of the heart. Learn about the roles of case study of myocardial infarction vessels including arteries, veins, and capillaries.

Describe the pulmonary, coronary and systemic circulatory systems. What prescription is given for a healthy heart? How can the heart's health be monitored by a physician? Define echocardiograph. Define electrocardiography. Describe how an echocardiogram works. List information about the heart that can be gained from an echocardiogram. What information cannot be learned from an echocardiogram. Which health professional would be responsible for performing an echocardiogram?

Vital signs had stabilized, his chest pain was relieved by nitroglycerin, case study of myocardial infarction, and breathing was made easier by the increased oxygen flow. A chest radiograph x-ray and echocardiogram were also performed. The patient's EKG findings were carefully reviewed by the ER physician and the on-call cardiologist was summoned.

There are several algorithms flow chart protocols for treating patients with chest pain suggestive of an acute heart attack. They include the patient's symptoms and history; the interpretation of the lead EKG; the results of cardiac enzyme markers and cardiac-specific proteins, the echocardiogram results and others. Intravenous streptokinase to dissolve clots and promote vascular healing.

Admission to the coronary care unit CCU for careful observation and additional testing. Intravenous beta blockers for decreasing oxygen demand to the heart, as well as other symptoms. Continued aspirin therapy mg twice a day Treatment of heart attack patients depend on several factors: The cardiologist's assessment, results of diagnostic testing and the patient's overall response to initial therapy.

More aggressive options may be needed. There are several websites listed under "additional links of interest" that will give the interested student an overview of heart attack treatments such as angioplasty and coronary bypass surgery.

Case Question Describe how beta blockers, streptokinase, and aspirin therapy are effective heart attack treatments. Cardiac Markers Cardiac markers are biomarkers measured to evaluate heart function. They are often discussed in the context of myocardial infarction, but other conditions can lead to an elevation in cardiac marker level. The results of the blood drawn in the ER were similar. As expected, in what appears to be a myocardial infarction of the anterior left ventricle as shown by the depressed ST segment on the electrocardiograph.

This baseline information is critical for physician's assessing the scope of damage to the heart, as well as predictive of possible complications from the loss of blood supply to cardiac tissue. Over the next several days, additional cardiac enzyme measurements will be performed and compared to these early results. Case Questions How does measuring the level of cardiac enzymes help detect a myocardial infarction MI?

Why are Mr. Dixon's cardiac enzyme levels normal or only slightly elevated, even though it appears he has just experienced an acute MI? What health care professional is responsible for determining cardiac enzyme levels? Dixon was admitted to the hospital's coranary care unit CCU and carefully monitored by specially-trained coronary care nursing personnel.

In patients with an AMI, the risk of sudden death is usually within the first 24 hours of the initial attack. What is an angiogram? Why is this test done? What health care professional assisted the physician in performing the angiogram? As we see from the results above, case study of myocardial infarction is a significant rise in the cardiac serum enzymes and the cardiac-specific protein troponin-I.

This is expected in patients with an with AMI and represents the heart's delayed response to release of these substances after tissue damage. Typically, these markers "plateau" after hours and then begin to return to normal as the heart tissue heals.

The risk factor tests show increases in total cholesterol, trigycerides and phospholipids. These case study of myocardial infarction lipids fats bound to their carrier protein molecules and abnormal case study of myocardial infarction are contributors to the formation of coronary plaque, case study of myocardial infarction. The decrease in High Density Lipoproteins the so-call "good cholesterol" is significant because they play an important role in bringing cholesterol back into tissue, thus reducing plaque formation by reducing the amount circulating in the bloodstream.

The increase in the "bad cholesterol" LDL, is also significant because it increases oxidative processes that contribute to plaque formation in the coronary vessel wall.

Dixon continued to improve and was transferred to the regular medical floor of the hospital for continued observation of vital signs, monitoring of serum cardiac markers and other key parameters.

After 6 days, he was discharged from the hospital with specific orders for postAMI recovery. The keys to his survival were the quick action by his wife by calling and the EMTs, who administered lifesaving, on-scene assessment and treatments that contributed greatly to his survival. Prompt emergency room care by physicians and critical personnel, coupled with proper treatments and care gave this patient a second chance.

In the long run, and to help reduce further cardiac problems, Mr. Dixon will have to make case study of myocardial infarction lifestyle changes: These will include controlling weight and making dietary changes, reducing work-related stress, stopping smoking and implementing a plan for moderate exercise. A patient presented with classic symptoms of a heart attack. A blood clot had formed in a coronary artery narrowed by atherosclerotic plaque formation, usually related to high blood lipoproteins such as triglycerides, cholesterol and lipids.

This in turn cut off the blood supply to an area of heart muscle, medically called ischemia. Symptoms include acute chest pain, often radiating down the arm, sweating, case study of myocardial infarction, vomiting and shortness of breath, case study of myocardial infarction. His wife called and within minutes emergency response personnel were administering life-saving care, including medication, breathing assistance and other measures.

Transported to the emergency room, diagnostic tests such as the electrocardiogram, echocardiogram, MRI and serum cardiac markers helped confirm an acute myocardial infarction commonly called a heart attack. This critically ill patient was admitted to the hospital's coronary care unit where he received around-the-clock care. Cardiologists, critical care nurses and monitoring of cardiac damage by blood tests and procedures such as the angiogram are critical to helping a patient recovering from a heart attack.

Dixon received aspirin, anticoagulants Streptokinase to prevent further clots, a beta blocker medication to reduce cardiac demand and continued monitoring of essential serum cardiac markers. After hospitalization for several days, the patient was released to further recover at home. He will have to make several lifestyle changes to include smoking cessation, case study of myocardial infarction, diet and stress reduction.

Medications are available to reduce cholesterol levels, regulate blood pressure and other abnormalities that contribute to coronary heart disease risk.
