Examples of myocardial infarction in the following topics:
-
- Ischemic heart disease (IHD), or myocardial ischaemia, is a disease characterized by ischaemia, or reduced blood supply to the heart muscle, usually due to coronary artery disease and myocardial infarction.
- Acute chest pain- acute coronary syndrome, unstable angina or myocardial infarction
- An EKG is performed, looking for changes that are characteristic of a myocardial infarction.
- The diagram depicts a myocardial infarction (2) of the tip of the anterior wall of the heart (an apical infarct) after occlusion (1) of a branch of the left coronary artery (LCA).
- Distinguish between the effects of myocardial ischemia and infarction on the heart
-
- This could result in angina and ultimately a myocardial infarction.
- These vessels are relatively narrow and thus vulnerable to blockage, which may cause a myocardial infarction.
- A myocardial infarction (heart attack) may be caused by prolonged ischemia (oxygen deprivation) in the heart, which occurs due to blockage of any of the coronary arteries.
- As the time period of ischemia increases, the hypoxic conditions cause muscle tissue to die, causing a myocardial infarction (heart attack).
- Myocardial infarction is one of the most common causes of death worldwide.
-
- An example is the case of ischemia brought on by a myocardial infarction (heart attack), where pain is often felt in the neck, shoulders, and back rather than in the chest, the site of the injury.
- The pain related to a myocardial infarction could either be referred pain or pain radiating from the chest.
- Classically, the pain associated with a myocardial infarction is located in the middle or left side of the chest, where the heart is actually located.
-
- ., Mycobacterium tuberculosis), post-infarct pericarditis (pericarditis due to heart attack), or Dressler's pericarditis.
- Acute pericarditis is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or even as a result of a heart attack (myocardial infarction).
- Due to similarity to myocardial infarction (heart attack) pain, pericarditis can be misdiagnosed as an acute myocardial infarction (a heart attack) solely based on the clinical data and so extreme suspicion on the part of the diagnostician is required.
- Ironically an acute myocardial infarction (heart attack) can also cause pericarditis, but often the presenting symptoms vary enough to warrant a diagnosis.
-
- Acute myocardial infarction (AMI or MI), commonly known as a heart attack, is a disease that occurs when the blood supply to a part of the heart is interrupted, causing death of heart tissue.
- The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death).
- With aging, the integrity of the endothelium lining the blood vessels and coronary arteries is reduced, increasing he likelihood of plaque formation and infarct development.
-
- A distinction should be made between myocardial ischemia and myocardial infarction.
- If the blood flow to the tissue is improved, myocardial ischemia can be reversed.
- Image showing right coronary artery (RCA), left coronary artery (LCA) and a infarct (1) with necrotic or dead myocardium (2).
-
- A sedentary and inactive lifestyle is associated with greater risk for hypertension, cardiac hypertrophy, atherosclerosis, and myocardial infarctions, due to the metabolic changes that accompany a sedentary lifestyle.
- Exercise helps prevent blood pooling and clotting, protecting against clots that could cause angina or myocardial infarction.
-
- Common causes of heart failure include myocardial infarction and other forms of ischemic heart disease, hypertension, valvular heart disease, and cardiomyopathy.
- The term heart failure is sometimes incorrectly used to describe other cardiac-related illnesses, such as myocardial infarction (heart attack) or cardiac arrest.
-
- How many individuals might we expect to be hospitalized for acute myocardial infarction (AMI), i.e. a heart attack, each day?
-
- During ventricular contraction, the wave of depolarization from the SA and AV nodes moves from within the endocardial wall through the myocardial layer to the epicardial surface of the heart.
- The Purkinje fibers are located just beneath the endocardium and send nervous impulses from the SA and AV nodes outside of the heart into the myocardial tissues.
- The dark area on the heart wall is scarring from a previous myocardial infarction (heart attack).
