Why does pain from a myocardial infarction radiate to the neck and sometimes down the arm?

Why does pain from a myocardial infarction radiate to the neck and sometimes down the arm?

Several reasons: The sensory nerves that innervate the heart are not like the nerves in finger tips-the pain is "visceral" and cannot be localized like a pin prick. It's perceived as spreading out from its origin into adjacent structures. Moreover, the inner arm shares the same dermatome, ie, the nerves send signals to the same segment of the spinal cord and then to the brain which interprets it as the same. ...Read more

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

Why does pain from a myocardial infarction radiate to the neck and down the arm?

Sensory: The sensory fibers from the neck and arm go through the same nerve connections as the sensory fibers from the heart/lungs and the brain may have difficulty distinguishing where the problem is actually coming from. ...Read more

What is the most common complication of early myocardial infarction?

Arrhythmia: The most common early complication of myocardial infarction is arrhythmia typically ventricular fibrillation. If this occurs in the hospital, it responds promptly to cardioversion. If it occurs outside the hospital it can result in sudden death. The highest period of risk occurs in the first 48 hours. ...Read more

Please tell me if angina pectoris and myocardial infarction are the same disease?

Please tell me if angina pectoris and myocardial infarction are the same disease?

No.: Angina Pectoris refers to chest pain, specifically spasms of the pectorals muscle, but usually the chest in general. This MAY be a symptom of a heart attack, which is also called, a myocardial infarction (MI). Myocardial means heart muscle and infarction is the lack of blood flow, causing the MI, and then, the angina pectoris. Chest pain may also be caused by other things besides the heart. ...Read more

Please explain the high glucose level and high fbs in patients with myocardial infarction?

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

Does ischemia or thrombosis cause myocardial infarction?

Does ischemia or thrombosis cause myocardial infarction?

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

How is ischemia linked to myocardial infarction, along with thrombosis?

How is ischemia linked to myocardial infarction, along with thrombosis?

MI: Ischemia is a state of insufficient blood supply to an organ, in this case the heart. When the condition persists it causes death of the tissue/organ - myocardial infarction. The cause of limited supply can be a narrowing of the supplying blood vessel, a blood cloth (thrombosis), a combination of both, or an increased tissue energy need such as in fever/sepsis etc... ...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
