Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

How high will the ck-mb be elevated if there is a myocardial infarction?

How high will the ck-mb be elevated if there is a myocardial infarction?

Depends: The elevation of ck-mb is in direct proportion to the size of the infarction. The highest i personally have ever seen was about 1000 but that is very unsual. Also, ck-mb will rise as a % of the total circulating ck. Normall ck-mb is less than 1.5% of total ck. After infarction, ck-mb will go to anywhere between 2.5-15% of total ck. ...Read more

Why is there ST segment elevation during a myocardial infarction?

Why is there ST segment elevation during a myocardial infarction?

Ecg: The ST segment elevation is caused by an electrical potential difference in that phase of the cardiac cycle between the dying cardiac muscle and normal parts of the heart and the vector direction of that potential difference as manifest on the ecg. ...Read more

Why is the t-wave inverted in myocardial infarction?

Why is the t-wave inverted in myocardial infarction?

Repolarization: The t wave on the electrocardiogram reflects the pattern of electrical repolarization in the heart. During a myocardial infarction, the pattern of electrical repolarization is reversed resulting in a reversal of the axis of the t wave. ...Read more

What is the point of a myocardial perfusion scan [nuclear test]?

What is the point of a myocardial perfusion scan [nuclear test]?

Cardiac imaging...: The myocardial perfusion scan is performed mostly to detect ischemia. It can also detect infarction (heart attack) as well as ejection fraction, wall motion abnormalities, and ventricular volumes. ...Read more

What is the point of a myocardial perfusion scan [nuclear test]?

Cardiac stress test..: A myocardial perfusion scan is used to detect ischemia or infarction (heart attack) and also to evaluation cardiac function (ejection fraction) and ventricular volumes. If there is significant ischemia sometimes a stent can be placed to prevent infarction. ...Read more

If troponin is blood gold standard for diagnosis of miocardial infarction at the ER,why is still used ck and ckmb?

If troponin is blood gold standard for diagnosis of miocardial infarction at the ER,why is still used ck and ckmb?

Good question: Troponin is a good test in the right situation but in many situations more data makes a diagnosis more probable. No test is perfect ...Read more

Is a high CRP the reason for vasculitis(leukocytoclastic-idiopathic) or is vasculitis the reason for a high crp?

Is a high CRP the reason for vasculitis(leukocytoclastic-idiopathic) or is vasculitis the reason for a high crp?

Second choice: CRP (and esr) is raised when there is an inflammatory condition of any kind going on in the body. So the vasculitis is causing its elevation. ...Read more

Had a CT A done, this was the results Mild calcification of the left main. Otherwise normal coronary arteries. What does that mean?

Had a CT A done, this was the results Mild calcification of the left main. Otherwise normal coronary arteries. What does that mean?

Occult CAD present: There is evidence of coronary atherosclerosis in your arteries atleast in the left main artery and albeit mild. Over time cholesterol hardens and that is what CT scan picks up. So at your young age if there is early atherosclerosis, you should have your fasting lipid panel be checked and then modify your lifestyle to mitigate progression of cholesterol build in your arteries. ...Read more

Very mild reversible ischemia my stress test shows there is very mild ischemia in the anterior wall in the LAD territory.What does that mean?

Very mild reversible ischemia my stress test shows there is very mild ischemia in the anterior wall in the LAD territory.What does that mean?

Blood flow: Reversible ischemia means that an area of your heart muscle is not getting adequate blood flow (at times) but then the blood flow "catches up" (i.e. Reversible). The lad is the left anterior descending coronary artery - it's an important blood vessel. The lad may have a blockage - would recommend seeing your cardiologist. ...Read more

Why is there chest pain present with a myocardial infarction?

Why is there chest pain present with a myocardial infarction?

Chemical: During infarction ischemia leads to production of Adenosine which mediated chest pain. The pain fibers are not specific so some people feel in the chest others in the arm or neck. ...Read more

Please explain why is it that the rbc, hemoglobin and hematocrit level of a patient with congenital heart disease is decreased?

Please explain why is it that the rbc, hemoglobin and hematocrit level of a patient with congenital heart disease is decreased?

Nutrition: The most common reason that hemoglobin and hematocrit are decreased is iron deficiency. In most cases, this is due to either inadequate nutrition (low iron intake) or blood loss (including frequent blood sampling.) neither of these reasons is truly caused by the heart defect, but children with congenital heart disease are at increased risk for either problem. ...Read more

Very mild reversible ischemia my stress test shows there is very mild ischemia in the anterior wall in the LAD territory.What is that mean?

Reduced blood supply: Ischemia means reduced blood supply to a part or muscle. The lad refers to one wall of the heart. This means you should follow up with your doctor or a cardiologist. You are at risk for heart disease, but it doesn't tell you how great is the risk. ...Read more

What is the significance of a non Q wave heart attack?

What is the significance of a non Q wave heart attack?

EKG finding: A q wave is a finding on the electrocardiogram seen after a completed myocardial infarction (heart attack). In some patients with heart attack, the electrocardiogram will demonstrated q-wave. In other patients, a q wave will not develop. In general, q wave myocardial infarctions are larger and associated with st elevation in the early phase of the heart attack. ...Read more

Is a coronary calcium ct scan a good test to see of there is plaque in the heart arteries? how accurate is it? my cta was inconclusive. heart rate fas

Is a coronary calcium ct scan a good test to see of there is plaque in the heart arteries? how accurate is it? my cta was inconclusive. heart rate fas

Coronary Calcium: Coronary Calcium analysis is a method to detect calcified cholesterol in the coronary arteries. A score of zero is quite helpful and predictive in the correct age group. The difficulty is that in younger people, there may be noncalcified cholesterol plaques in the arteries which would not be detected on a coronary calcium screening test, so cardiac CTA or invasive angiography would be considered. ...Read more

Infarction (Definition)

When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more

Heart Attack (Definition)

A life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
