What is the histopathology of myocardial infarction?

Histopathology The histology of myocardial infarction changes over the time-course of the disease. At time 0, there are no microscopic histologic changes. Under light microscopy, within 0.5 to 4 hours, waviness of fibers at the periphery of the tissue is seen. Glycogen is depleted.

Can a myocardial infarction go undetected?

Myocardial infarction may be “silent” and go undetected, or it could be a catastrophic event leading to hemodynamic deterioration and sudden death.[1] Most myocardial infarctions are due to underlying coronary artery disease, the leading cause of death in the United States.

What are the two categories of acute myocardial infarction (MI)?

Acute myocardial infarction can be divided into two categories, non-ST-segment elevation MI (NSTEMI) and ST-segment elevation MI (STEMI). Unstable angina is similar to NSTEMI.

What is used to identify a myocardial infarction in a patient?

Troponin I concentration and the 3-hour change in its concentration provide valid diagnostic information in patients with suspected myocardial infarction and chronic AF.

What is meant by myocardial infarction?

A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don't get enough oxygen. This happens when blood flow to the heart muscle is blocked.

What is a silent myocardial infarction definition?

Silent myocardial infarction (SMI) relates to absence of symptoms usually associated with myocardial ischemia. Its risk factors include heavy smoking, family history of heart disease, age, high blood cholesterol and systemic blood pressure, diabetes, and overweight [3, 4].

What is prior myocardial infarction?

Abstract. Background: Prior myocardial infarction (MI) is a known risk factor for long-term mortality among acute MI patients; but its prevalence and implications for the short-term outcomes of patients with a new, acute MI remain uncertain.

What causes a myocardial infarction?

Myocardial infarction (MI) usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in an epicardial coronary artery, resulting in an acute reduction of blood supply to a portion of the myocardium.

What are the types of myocardial infarction?

The three types of heart attacks are: ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI)...Symptoms and signs of a STEMInausea.shortness of breath.anxiety.lightheadedness.breaking out in a cold sweat.

Which myocardial infarction is referred to as a silent MI?

silent myocardial infarction refers to the presence of a myocardial infarction not clinically recognized at one point in time and discovered at a later point in time, while silent myocardial ischemia refers to the presence of objective evidence of myocardial ischemia in the absence of symptoms related to that ischemia ...

What is a silent myocardial infarction and why did it happen to this patient?

Silent myocardial ischemia is a condition of reduced oxygen-rich blood flow to the heart that occurs in the absence of chest discomfort or other symptoms of angina, e.g., dyspnea, nausea, diaphoresis, etc.

How is silent MI diagnosed?

Imaging tests, such as an electrocardiogram or echocardiogram, are the only way to identify a silent heart attack. If you think that you've had a silent heart attack, talk to your health care provider. A review of your symptoms and health history and a physical exam can help your provider decide if you need more tests.

What does MI mean in cardiac?

However, cardiac markers are not elevated. [1][2][3] An MI results in irreversible damage to the heart muscle due to a lack of oxygen. An MI may lead to impairment in diastolic and systolic function and make the patient prone to arrhythmias. In addition, an MI can lead to a number of serious complications.

What happens to the monocytes in an atherosclerotic rupture?

This leads to decreased oxygen delivery through the coronary artery resulting in decreased oxygenation of the myocardium.

When to use ASA for myocardial infarction?

ASA is used for primary prevention of myocardial infarction (MI) in men and in women older than 65 years. Aspirin for primary prevention may be used in women ages 55 to 79 years when the potential benefit of a reduction in MI outweighs the potential harm of increased GI hemorrhage. This patient has no previous history of MI, ...

Hemorrhage involves a decrease in blood pressure, bruising, and lumbar pain. The patient has pleuritic pain, which is not consistent with the chest pain of a myocardial infarction. A patient who takes warfarin [Coumadin] is brought to the emergency department after accidentally taking too much warfarin.

What is the cause of cardiac valve disease?

Rheumatic fever. Rheumatic fever, a streptococcal infection, is the major cause of cardiac valve disease. The patient has a total cholesterol of 190 with a high-density lipid (HDL) of 110 and a low-density lipid (LDL) of 80.

How long does it take to walk 2 miles after a calf surgery?
