What confirms myocardial infarction?

What confirms myocardial infarction?

Toponins,clinic,wall: Acute cardiogenic shock, .Ventricular arrythmias, infarct syndrome, flash pulmonary edema, wall motion abnormalities, syncope, presyncope, cardiac arrest, . It takes 4 hours for troponins to elevate after the infarct begins. That is why clinical symptoms dictate emergent coronary interventions. Troponins may still be normal within minutes of a life threatening myocardial infarct. ...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

Myocardial infarction causes?

Myocardial infarction causes?

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

Define?accute anteroseptal myocardial infarction, atherosclerotic obstructive coronary artery disease, pulmonary edema, cardiogenic shock, hypokalemia

Here are some...: A 400-letter space is impossible to address many indicated subjects as questioned here. Why not type in the terms as keywords to search online? Thereby you surely gain a lot of pertinent information to feed your appetite of knowledge. Or you may just ask your doc who should be able to answer your questions to the point much easier. ...Read more

What is myocardial perfusion scintigraphy?

What is myocardial perfusion scintigraphy?

Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read more

Can angio cardiac CT detect angina?

Can angio cardiac CT detect angina?

No: Angina is a clinical symptom. The angiogram r cardiac ct are both imaging studies. We can look at imaging studies and suggest that there is narrowing of the coronary arteries which may cause angina. ...Read more

What is acute coronary syndrome myocardial infarction?

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. ...Read more

What is an unrecognized non-q-wave myocardial infarction?

What is an unrecognized non-q-wave myocardial infarction?

Q vs. non-Q: When a heat attack causes a full thickness ("transmural") heart attack, the ekg reveals the resulting scar by inscribing a "q" wave in the leads that correspond to the damaged area. If the heart attack was not transmural or occurred in an area not seen well on ekg, there may be no q waves. If you had no symptoms at the time of the heart attack (25-50% of all attacks), it will be "unrecognized.". ...Read more

the same thing: Arteriosclerotic cardiovascular disease means blockages in the coronary arteries. The manifestation of coronary artery blockage is a heart attack. When this happen suddenly, we say it is acute. ...Read more

What is an inferior myocardial infarction from?

Many poss causes: An inferior mi refers to a heart attack on the inferior wall of the heart muscle. 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 all contribute to this process. ...Read more

Does a myocardial perfusion scan show blockage in the heart?

Blood Perfusion: The angiogram shows anatomic blockage of coronary arteries. The myocardial perfusion scan shows blood flow to the heart. Blood flow can get past large blockages (shown on angiography) if there are enough small, collateral vessels present. ...Read more

My nuclear images suggest apical septal ischemia.

Ischemia...: Most hearts have physiologic apical thinning which can sometimes be misinterpreted on nuclear stress test images. In addition, stress test images in patients with left bundle branch block can appear as septal ischemia if exercise stress is done rather than pharmacologic. The fact that both the apex and septum are involved in your case make it more likely to be real ischemia probably in lad. ...Read more

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

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read more
