What is inferior myocardial infarction?
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
How is inferior myocardial infarction treated?
FIELD TREATMENT Fluid infusion is the mainstay of treatment for patients with RVI. In the case of an inferior MI with right ventricular involvement, the administration of nitroglycerin and morphine could cause an abrupt drop in blood pressure.
What are the symptoms of a patient suffering from a myocardial infarction?
Symptoms
- Pressure, tightness, pain, or a squeezing or aching sensation in your chest or arms that may spread to your neck, jaw or back.
- Nausea, indigestion, heartburn or abdominal pain.
- Shortness of breath.
- Cold sweat.
- Fatigue.
- Lightheadedness or sudden dizziness.
Is myocardial infarction curable?
How is acute myocardial infarction treated? Heart attacks require immediate treatment, so most treatments begin in the emergency room. A minimally invasive procedure called angioplasty may be used to unblock the arteries that supply blood to the heart.
What causes inferior wall myocardial infarction ( MI )?
Inferior Myocardial Infarction – StatPearls – NCBI Bookshelf Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
What kind of muscle is affected by myocardial infarction?
Myocardial Infarction. Transmural MI affects the full thickness of affected muscle segments, from endocardium through midmyocardium to epicardium; nontransmural MI does not extend through the full thickness of the myocardial segments and is limited to endocardium or to endocardium plus midmyocardium.
When does the subendocardial infarction become transmural?
(b) At 40 minutes, subendocardial infarction is seen. (c) At 3 hours, the subendocardial infarction is seen extending to the midmyocardial region. (d) Beyond 6 hours, the infarct becomes transmural, extending from the subendocardial to the subepicardial layers.
Where does nontransmural mi affect the muscle segments?
Transmural MI affects the full thickness of affected muscle segments, from endocardium through midmyocardium to epicardium; nontransmural MI does not extend through the full thickness of the myocardial segments and is limited to endocardium or to endocardium plus midmyocardium.
