Severely reduced perfusion in the inferior wall of the heart typically indicates compromised blood flow to that area, often due to coronary artery disease or blockage in the coronary arteries supplying the inferior wall, such as the right coronary artery. This can lead to ischemia, resulting in symptoms like chest pain or heart failure. If left untreated, it may progress to myocardial infarction (heart attack), damaging the heart muscle. Timely medical intervention is crucial to restore blood flow and prevent further complications.

What is small perfusion defect of the lv apex and distal anterior for chest wall attenuation?
A small perfusion defect of the left ventricular (LV) apex and distal anterior wall, observed in a myocardial perfusion study, suggests reduced blood flow to these areas, which could indicate ischemia or infarction. The mention of "chest wall attenuation" refers to the phenomenon where the overlying chest wall tissues absorb or scatter the imaging signal, potentially obscuring the true myocardial perfusion status. This attenuation can lead to misinterpretation of the defect, emphasizing the importance of correlating imaging findings with clinical context and possibly utilizing additional imaging modalities for accurate diagnosis.
What does it mean a diaphragmatic attenuation versus reverisbility in the inferior wall?
Diaphragmatic attenuation typically refers to a decrease in image quality in the inferior wall of the heart due to interference from the diaphragm. Reversibility in the inferior wall usually indicates that a defect revealed during imaging is potentially reversible, often highlighting areas of reduced blood flow that may improve with treatment.
What is transmural perfusion pressure?
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
What is q waves in the inferior leads?
Q waves in the inferior leads on an ECG indicate previous myocardial infarction affecting the inferior wall of the heart. They represent an area of scar tissue where the electrical activity is disrupted, resulting in a negative deflection. The presence of pathological Q waves suggests permanent damage to the heart muscle in that region.
What is a Partially reversible defect of the inferolateral wall?
A partially reversible defect of the inferolateral wall typically refers to a condition observed in cardiac imaging, such as a myocardial perfusion scan or cardiac MRI, where there is reduced blood flow or function in the inferolateral region of the heart muscle. This defect may indicate underlying ischemia or previous myocardial injury, but it is not completely fixed, meaning some functional recovery is possible with appropriate treatment, such as revascularization or lifestyle modifications. The term emphasizes the potential for improvement in heart function in that specific area, depending on the severity and duration of the underlying condition.

Can you give nitroglycerin to patients with inferior wall MI?
No
Can you give nitroglycerin to a patient with inferior wall MI?
No
What is interior infarction?
An inferior, not interior, infarction is a subclassification of a heart attack. An inferior myocardial infarction occurs when there is a blockage in the inferior wall of a coronary artery.
Inferior wall ischemia?
An inferior wall mycardial infarction is a heart attack involving the inferior portion of the left ventricle, and in many cases the right ventricle. This is caused by occlusion of the right coronary artery. This can also indicate ischemia (poor oxygenation) of the AV node and bundle of HIS, as these structures are also supplied by the right coronary. An inferior wall MI can be seen in the inferior leads II, III, and AVF.
What is inferior wall mild hypokinesia?
underactive contracyin of heart muscle
Ptotic kidney and ptosis is the same?
Ptosis in relation to the kidnery, is when the fatty material surrounding the kidneys is reduced or too meager in amount, the kidneys are less securely anchored to the body wall and may drop to a lower or more inferior position in the abdominal cavity.
What does abnormal myocardial perfusion scan with a small area of decreased perfusion on stress imaging anterior lateral wall mean?
It could be an indication of a blocked coronary artery, however the definitive proof would be a cardiac cath to actually visualize the flow in the vessel and see if it is something that needs to be intervened on.
What wall forms most of the inferior border of the heart?
the inferior border of the heart is formed by both the right and leftventricles, but the inferior (diaphragmatic) surface of the heart isprimarilymade from the Leftventricle. Kaplen Anatomy 2012, section 3 gross anatomy, page 212.
What tissue does the inferior epigastric artery supply?
Rectus abdominis & medial part of the anterolateral abdominal wall
Why will you not give morphine in inferior wall myocardial infarction?
Morphine decreases pre-load and after-load and because the Inferior wall is effected the right ventricle is effected. If you do not have enough blood entering the right ventricle when the area is necrotic to begin with you will not be pumping enough blood to perfuse sufficiently. In addition the decreased after-load in in conjunction with the decreased blood pressure caused by the failure of the right ventricle there will not be enough "back-flow" in the cardiac vascular system. In summation if can cause bottoming out of a patient's blood pressure and further cardiac hypo-perfusion. In some cases it has been shown to work if a normal saline or ringers lactate bolus is infused prior to morphine administration.
