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.
Consequently, does inferior infarct mean heart attack?
An inferior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the inferior side of the heart. Inferior MI results from the total occlusion of either the right coronary artery in 85% of the cases or the left circumflex in 15% of the cases.
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.
Also, how long can you live with myocardial infarction?
About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
What are 3 common complications of a myocardial infarction?
Complications of MI include arrhythmic, mechanical, and inflammatory (early pericarditis and post-MI syndrome) sequelae, as well as left ventricular mural thrombus (LVMT) (see the following image).
What causes inferior myocardial infarction?
An inferior myocardial infarction results from occlusion of the right coronary artery (RCA). This can cause a ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.
What does possible inferior infarct age undetermined mean on an ECG?
If the finding on an ECG is “septal infarct, age undetermined,” it means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.
What is the drug of choice for myocardial infarction?
The pain of myocardial infarction is usually severe and requires potent opiate analgesia. Intravenous diamorphine 2.5–5 mg (repeated as necessary) is the drug of choice and is not only a powerful analgesic but also has a useful anxiolytic effect.
What part of the heart is affected by an inferior MI?
While inferior wall MIs traditionally have a good prognosis, there are a few factors that may increase mortality. Approximately 40% of inferior wall infarctions also involve the right ventricle. Right ventricular infarctions are very pre-load dependent, and nitrates may precipitate a drop in blood pressure.
What should I do after myocardial infarction?
What can I do to help myself after having a heart attack?
- Stop smoking. If you smoke, giving up smoking is the single most effective way to reduce your risk of having a further heart attack. …
- Change your diet. …
- Lower your cholesterol. …
- Alcohol. …
- Physical activity and exercise. …
- Weight. …
- Check your blood pressure regularly. …
- Diabetes.
Which complication is most likely to occur after a myocardial infarction MI?
After arrhythmias and cardiogenic shock, the commonest cause of death after acute MI is rupture. Cardiac rupture complicates 10 per cent of acute MIs and occurs in the healing stages at around five to nine days.
Which of the following is the most likely complication of inferior wall myocardial infarction MI?
Papillary muscle rupture after acute myocardial infarction can occur as a complication of an inferior MI (right coronary artery supply) since the posteromedial papillary muscle is the most likely to rupture.
