Pathophysiology Of Chest Pain In Myocardial Infarction
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
Chest pain and possible myocardial infarction. Ecg reveals sinus tachycardia. What does this mean at 50?
Hey doc. ... may I kno d answer for why do pain radiates from chest to arm neck and jaw in myocardial infarction? Thank u
Heart attack: Inferior myocardial infarction is a heart attack on the bottom of the heart. This portion of the heart is frequently served by the right coronary artery but occasionally by the circumflex coronary artery. When the artery closes, the bottom of the heart does not get any blood, and the muscle of the heart is injured.See 1 more doctor answer
Electrical: A heart attack damages muscles in the heart. The flow of the electrical current throughout the wall changes when having to go around the damaged muscle, resulting in certain ekg changes, since ekg's show the path of electrical current in the heart. There are different changes, de[ending on which part of the muscle is damaged.
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.See 1 more doctor answer

It can if...: Asthma can lead to a heart attack if you have coronary arterial disease. The stress from an asthma attack can lead to an mi, or the inflammation associated with uncontrolled asthma might lead to rupture of the plaque in the coronary artery, again leading to mi. This might be the mechanism that explains the increase in heart attacks during high pollution days... But might not.See 3 more doctor answers
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.See 1 more doctor answer
Atherosclerosis: 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.See 1 more doctor answer
Atherosclerosis: Most myocardial infarctions are associated with atherosclerotic disease
Continuum: Both are a result of inadequate blood supply to the heart muscle. Acute coronary syndrome means that the imbalance is sufficient to cause symptoms that prompt aggressive intervention, but may not result in permanent heart damage; a myocardial infarction implies that overt heart damage has occurred, hence positive markers of tissue damage.
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
