Q: 

What is the difference between Angina Pectoris and myocardial infarction?

A: Angina pectoris is a crusiating egoning pain experienced on the left side chest wall called precordium may have extension to left arm and left side neck and jaw also or back side of chest with lots of perspiration!It is a symptom arising from low blood supply to heart muscle!!Where as myocardial infarction means some part or area of the heart muscle it self is on its death way !or is died and have become non elastic fibre permanently !!this INFARCT patch will remain for ever on the heart surface where as Angina will go away using coronary dilator drugs.Angina may become a cause of infarction or heart attack arrest !Always YouRmE myocardial infarction (aka heart...


Q: 

What Is the Most Common myocardial infarction Pathophysiology?

A: myocardial infarction is the formal medical term for a heart attack. The term specifically refers to an infarction of the myocardium, which simply translates to damage of the inner muscular wall of the heart. This is significant since the myocardium is responsible for pumping away from the heart. Should this function become impaired, ischemia will occur, a condition characterized by a lack of sufficient blood and oxygen supply to the heart. While there are numerous risk factors that can contribute to a diseased heart, the most common myocardial infarction pathophysiology is atheriosclerosis. Atheriosclerosis is a chronic inflammatory disease that compromises arterial...
Q: 

can Pulmonary TB be an underlying cause of myocardial infarction? my grandfather''s death certificate listed that theunderlying cause of death is acute MI and hypertension was listed as a significant condition contributing to death.however, he was hospit

A: Hi,Both pulmonary TB and myocardial infarction can lead to the death of the patient. However, pulmonary TBdoesn?t lead to myocardial infarction. myocardial infarction is caused by the narrowing of the coronaryvessels due to the development of the atherosclerotic plaque. I sincerely hope that helps. Take care....
Q: 

When a myocardial infarction occurs, what is it characterized by?

A: myocardial infarction is a heart attack. If you are a woman you may not have the typical symptoms. Mine were fatigue and constantly eating sweets! Jeez, it would take hours to really answer that. Here are some answers to your direct questions. Yes an MI will cause necrosis to the affected part of the heart. The longer treatment is delayed, the further the necrosis will spread. Irritation of the pericardium will cause severe discomfort, but won''t neccessarily result in an MI. Fluid build up between the pericardium and the heart is called pericardial tamponade. That will gradually decrease the space the heart has to contract until there is no more room for it to pump. A faulty heart valve will result in a backwards...


Q: 

Do you know what acute myocardial infarction means please?

A: myo= muscle cardial= pertaining to the heart it''s a heart attack. acute being a severe heart attack. Heart attack. That is the fancy name for a heart attack. Infarct means a cutting off of the blood supply as in what happens in heart attack. yes eactly my sister died age 33 this year from it. A myocardial infarction (MI) is a heart attack. Which can occur for a number of different reasons. (i.e.: burst plaque in a coronary artery, spasm from drug use, thrombus (from a DVT) that has crossed a PFO (or hole in the heart)... etc.) Acute means sudden. People who have an Acute MI go directly to the Cardiac Catheterization lab from the ER. Here, they will try to open the blockage using a balloon & stent. Unfortunately, sometimes folks having...


Q: 

What could be done to a case of myocardial infarction at home?

A: If you have someone with that serious a condition and are treating it at home the best thing that you can make for it is burial arrangements. That needs a doctor ASAP. Call 911. Give O2 if available as well as nitro if the person is prescribed it. Give two 81 mg asprin (if not allergic) and get them transported to a hospital ASAP. An MI means time is muscle tissue not getting enough oxygen. Take an asprin and get to the hospital. Of course you have to call emergency or take the patient to ER, and have all posible information available (blood group, previous exams, ECG etc). At home while waiting, as THE FIRST to do is make sure pulse and breathing are present, if the patient is conscious and you don''t feel pulse, make him/her COUGH ONCE, VERY HARD and feel if there is a pulse response....


Q: 

What is common in hypertension, hypercholesterolaemia, diabetes and smoking that leads to acute myocardial infarction?

A: Dear Sir, Your question is very pointed. The common thread in these four etiologies is that they all cause microvasular disease. myocardial infarction (heart attack) is caused by a lack of oxygen to the heart muscle (myocardium). This lack of oxygen (ischemia) is caused by either a blockage of the cardiac vessel supplying the heart muscle or due to contraction of these vessels. High blood pressure (hypertension, HTN) over time will make the vessels hard and non-compliant to changes required due to stress and oxygen demand. At some point, the vessels do not dilate to increase blood supply and with increased pressure, the walls of the vessels are unable to allow oxygen transport into the myocardium. Elevated cholesterol (hyperlipidemia,...


Q: 

Can you tell me why myocardial infarction usually occurs at the apex?

A: I haven''t been able to verify that this is true. What I can say is that the blood vessels which supply the heart start at the base and go toward the apex. So one could certainly hypothesize that the area farthest away would be most vulnerable. Here is a link to more information about myocardial infarction from the American Cardiology Association that you might find useful: http://www.americanheart.org/presenter.jhtml?

Q: 

I want to know about online advise about life after myocardial infarction, about span of medicines to be taken

A: Needs individualisation. You need to consult your Physician/Cardiologist. Treatment consists of both drugs(Pharmocotherapy) and Life style modifications. In general terms treatment can be remembered by the mnemonic:ABCDE: Aspirin, ACE-Inhibitors/ARB----Both provide heart protection. Blood pressure control and Beta blocker therapy. Cholesterol has to controlled with diet and statins. Cigarettes has to be stopped. Diabetes needs to be addressed and patient should be counselled on Drugs. Exercise: Minimum walking for at least for 45 minutes need to be stressed. In addition the current trend is early assessment for possible angiogram and other therapeutic measures. In general with current treatment modalities and other Healthy Life style measures one can hope to lead a perfectly normal life....


Q: 

What Are The Risks Of Recurrent Ischaemic Events After myocardial infarction: Prehospital, At 30 Days And At 1 Year?

A: Data from the WHO MONICA project in 38 populations from 21 countries show that 49% and 54%, respectively, of all men and women with an acute coronary event die within 28 days. About 70% of these deaths occur out of hospital on day 1 and it is generally accepted that a large proportion of these early deaths are the result of ventricular fibrillation. Thus provision of rapid access to a defibrillator remains the single most effective way to save lives in acute coronary syndromes. Following hospital admission the outcome of acute myocardial infarction is determined largely by left ventricular function. Before the introduction of thrombolytic and other reperfusion strategies, average in-hospital mortality from acute
