Why Does A Myocardial Infarction Cause High Esr
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
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.

Stress: Hi. High glucose and high FBS may, repeat MAY, be seen with acute MI, but is not an absolute finding by any means. Many people have had diabetes (which actually contributes to them having an MI) but it doesn't get diagnosed until they're in the hospital for the MI. MI is a serious stress to the body, and two principle stress hormones, epinephrine and cortisol, raise blood sugar. Control diabetes! Read more
Can you tell me what it mean when it says short pr interval and a high lateral myocardial infarction?
Different things: Short pr interval means that the conduction through the heart is accelerated - often because it is arising lower in the atrium than usual or because there is an accessory bypass tract. High lateral mi means that there has been a heart attack in the high lateral wall, often due to disease in the left circumflex artery, marginal branch, or a diagonal branch of the left anterior descending.

Many poss causes: Almost all heart attacks are the result of fatty deposits on the inside of arteries that break open and cause clotting which will blocks the artery (and the blood from flowing to the part of the heart the artery feeds). Family history, fatty diet, smoking, high blood pressure, diabetes and other disorders can all contribute to this process. Read moreSee 1 more doctor answer
No: Well I shouldn't be so definite. Who would have thought that ulcers would be caused by infection. There has been noted to be an increase in heart attacks related to certain infections including those involving the gums, so the cause and effect question has been raised. It has been suggested that inflammation plays a role. But at this time I think most doubt the cause and effect relationship. Read moreSee 1 more doctor answer
Depends on one's personal risks
smoking, obesity, hypertension, hyperlipemia, diabetes
, family history.
Simply, one blocks the feeding coronary artery to part of the heart muscle and low flow, or no flow causes ischemia which cause death of the heart cells, which is a heart attack!
myocardial infarction is the medical term. Ekg and lab tests show the damage. Read more

No: It's early repolariztion, a normal variant.Get a more detailed answer ›
Ischemia vs MI: Cholesterol plaque develops in the heart arteries. Progressive narrowing - usually greater than 70% - can lead to lack of blood flow to the heart muscle during exercise or rest and causes angina or ischemia. Myocardial infarction is due to the rupture of a plaque which causes a blood clot to form (thrombosis) in the artery blocking blood flow to that area of the heart muscle which then dies. Read more
Can you explain the physiological basis of elevated serum lactate and lactate dehydrogenase during or post myocardial infarction?
Ldh can be released from dying cells or congested cells
serum lactate is usually elevated from the person going into some degree of shock (this would usually be from a massive heart attack causing the other organs not to be well perfused with blood due major decline in the hearts pumping strength or function. Read more
No: But it can cause pulmonary embolism or migration of the clots to lungs. Clinically sometimes hard to differentiate, totally different conditions otherwise. Read more
Unique to person: In many occations not painfull at all. Most common symptom is chest pressure, heavyness, oppresion, shortness of breath not "pain", sometimes indigestion like symptoms. "silent" heart attacks are common in patients with diabetes. Still today about 50% of people die on their first heart attack. In many occations thinking" its not my heart", " its reflux", "indigestion", "my hiatal hernia"anything but. Read more
Various: The st segment is a portion of the electrocardiogram. A myocardial infarction can be described as st elevation myocardial infarction or non-st elevation myocardial infarction depending on the appearance of the electrocardiogram. Management of the 2 types of heart attack are somewhat different. Read moreSee 1 more doctor answer
Multiple methods: Myocardial infarction (mi) is suspected by symptoms usually including chest pain. The conclusive diagnosis is established based on a combination of specific abnormalities of the electrocardiogram (ekg) and presence of certain heart enzymes that leak into the blood during an mi. The most common enzymes are called ck-mb and troponin. Read moreSee 1 more doctor answer
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
