In angina there is pain due to decreased blood and oxygen supply to the heart. Once there's enough oxygen the heart tissue goes back to normal. There's stable (something you have been feeling for a long time in the same situation and hasn't changed) and unstable, the dangerous one, which can lead to myocardial infarction (these two are called acute coronary syndrome).
In myocardial infarction, the tissue actually dies, so even after the oxygen is restored, that particular part will never return to normal. Usually there's always a part that is only ischemic (low oxygen) but not dead yet, so its necessary to reperfuse (open those arteries) as soon as possible to save the sick but not dead tissue.
In a few words:
angina: reversible damage
infarction: irreversible, dead tissue.
i never understand difference between heart attack, conjustive cardiac failure and myocardial infarction.i always become confused while understanding all these terminologies. i am a medical student but never understnd it .please answer my question.i shall be very greatful
Have mild chest pains after walkng for 20 minutes. They last about 15 minutes and when I slow down they go away. The rest of the day I just feel somewhat tired. Had echo,stress test on tread mill and angiogram CT scan. They said my heart is fine but I have some indictation of blocked arteries. One of them appears to be about 55-70% but they do not want to do an angiogram with stent. I had a liver transplant last Dec 2009 and it is fine. I maintain a good BP and pulse rate is a little low. After walking my BP is about 119/65 and HR is 62. Always, but I do have morning hypertension and am taking Cozaar and Norvasc along with Prograff,Imuran--Immunosurpressants for LIVER and Bactrim. The seem to cause headaches EVERY night about 2am that last for several hours. thought I was having a stroke but they ruled that out. Went to ER several times thinking that I was having a heart attack. EKG shows nothing and the heart enzyme tests are negative. I am puzzled. My dentist who is an avid runner said that I may be having ANGINA and to take my NITRO with me. I don t want to stop walking but this has been gpoing on for 3 months and nothing has been diagnosed? Thank You.
my heart keeps stopping, its for several seconds then it restarts with an almighty thump. I have a terrible feeling of sinking when this happens. It started about 4 years ago and is getting more regular. I'm 33, 5'2“, approx 140lbs, female with no health probs but with family heart probs, ie angina, m.i, etc.

I have had migraine headaches since I was 12 years old; I am now 65 years old. Everyone in my family has them, both maternal and paternal sides. We can trace them back to my great-grandmother. I have been using Imitrex since it came on the market....
