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. ...Read more
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. ...Read more
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 more
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 more
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
Atherosclerosis: Most myocardial infarctions are associated with atherosclerotic disease ...Read more
Atherosclerosis MI: Atherosclerosis-hardening of the arteries due to cholesterol plaque buildup - the plaques are made up of fat, collagen, muscle cells and blood cells. The plaques rupture - lead to clot formation - thereby clogging the arteries. Decreasing blood supply to heart muscle. ...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 more
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 more
Many: The location is a major factor: left main blockage is most likely to be fatal. Proximal left anterior descending is also often fatal. Patient factors such as on-going tobacco use, uncontrolled hypertension, diabetes, anemia, pre-existing heart or kidney failure and advanced age all raise the risk. ...Read more
Multiple & varied: Chest pain, radiation to the arm, neck, jaw, sense of impending doom, sweating, feeling of weight on chest, tiredness, shortness of breath, feeling faint or dizzy etc. About a quarter of the mis especially in diabetics may have no recognizable symptoms. Sudden death may be the only symptom in some. ...Read more
Heart Emergency: 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 & the risk of death. ...Read more
? MI?: 18 year old boys don't have MI's almost ever. If they are feeling chest pain it is almost invariably reflux wherein stomach contents are being regurgitated up the esophagus and it is called heartburn. A key to diagnosing a true MI is that the pain is exercise induced-I.e. It gets worse when you're walking up the stairs or whatever and it gets better when you stop. If that is so, get to ER pronto. ...Read more
A heart attack: The septum is the wall that separates the right from the left side of the heart. Myocardial infarction, a heart attack, is caused by a blocked artery in the heart. If the artery blocked supplies the blood to the septum the result is called a septal myocardial infarction. ...Read more
Many approaches: There are many type of interventions to prevent heart disease. Eat a diet lower in saturated fats and chiolesterol. Increase your intake of fiber, fruits and vegetables. Start an exercise program, 30 minutes 5 days a week. See a doctor. Check your blood pressure, cholesterol and fasting blood sugar. Talk about family history. Know your risk levels and get started on therapies to modify them. ...Read more
ST elevation...: Many believe that an st elevation myocardial infarction means that it is a transmural infarct (involving the whole thickness of the myocardium). Some people refer to nstemi (non st elevation myocardial infarction) as non-transmural infarct (not involving the whole thickness of the myocardium). These definitions are somewhat debatable but thought you may be interested. ...Read more
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
