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

Life after a MI can be just as normal as anything else. However, depending on the extent of the MI and the damage it may have caused it can be a lengthy process. There may be some rehabilitation involved with physical and occupational therapies to strengthen the muscles and coordination skills.
As far as medicines are involved it could range from taking a simple aspirin a day to being put on blood pressure medication or other types such as coumadin to thin the blood. A type of diuretic may be prescribed also. Just know that the type of medication involved all depends on the cause of the MI. The doctors will use the cause of the heart attack as a guide as to how to treat it and prevent another one.
Take it easy after a heart attack. Rest is one of the things we find so hard to do. There may be a need to change ones life style to decrease the amount of stress too.
So you see, there's a lot of factors involved in treating a person after a MI and preventing another one.

Well, it's difficult to answer that question without knowing more about your case specifically, but I'll try to give some guidelines.
There are several classes of drugs that have proven helpful for people who have had a MI, including beta blockers and ACE inhibitors, both of which should be taken indefinately after the heart attack. Aspirin is also a life-saver and again is taken for life. A statin has been found to be helpful in the immediate aftermath of an MI as well as for prevention later, and especially for patients who have recieved stents, plavix is another drug that can help, the span of time over which it should be taken is currently not completely clear, but at least a year, probably more.

Please see the webpages for more details on Myocardial infarction.

Life after MI is more or less a bit under control. You have to make your controls, ECG, ECHO and other tests on a regular basis, say once in 6 months and some 1 in a year. Depending on the type of MI and the treatment generated after that (stent or by-pass surgery) changes the medicines you have to take. But overall list is this:

1. Aspirin - cannot live without it!
2. ACE inhibitors - the only medicine proven to lenghten life of MI patients, cant go without it.
3. Beta blokers - the less your heart beats per minute the more time it goes on beating
4. Statins - try to keep your coronary arteries open
5. Warfarin - if you have stent placed, then aspirin isnt enough to protect them from clogging. Warfarin is the drug
6. Plavix - A powerful helper to aspirin
7. Other antihypertensive, if you are hypertensive
8. Check out if you have diabetes or not, if you have then insulin enjections are the best life saving choice
8. Aerobic exercise 1 hour a day - think it as a medicine, brilliant choice
9. Change your eating habits - low cholesterol, low salt, high fiber diets
10. MI is most of the time the trigger for people to change their lifes to a more fascinating and healthy style. You'll be more happy, more caring, more lovefull, more cheery and funny. You'll be less stressful and you'll like every minute you are spending, cos you have learned that life is spended. There are lots of people calling the day they had MI their second birthday.

Where i work pts with mI are classfied as core measures. Usually at discharge the docs prescribe an asprin, plavix, ace inhibitors, and beta blockers
like digoxin and verapamil
coumadin, antihypertensives if you have hypertension
los sodium, low cholesterol and low fat diet

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.
