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
husband had abnormal ecg echo test clear but positive stress test showing he may have had a heart attack.he is 59 and father had angina died at 68 with stroke husband is non smoker and non drinker,has to have angiogram,could it be a false alarm or am i deluding myself?
I have seen two doctors for chest pain. I have had stress test tilt table test and angiogram done. One doctor says that it is coronary artery spasms and the other says its angina. I quit my stressful job, and haven t had an attack in awhile. But in the last week I have had two attack. They seem to be getting worse. I went to the ER for this last one and they said everything looked ok. Can you have a mini heart attack and not know? I am still experiencing chest pain, but don t want to go back to the ER.
What are the symptoms that differentiate a gastric /acidity pain from Angina(heart )? I am usually getting gas problem due to stress and constipation.. but sometimes even with clear stomach but his could be heart related.. how to eliminate anything serious ??
i have cadiomyothropy, angina, heart spasms, extra heart beats. i take heart meds an nitro pills. recently have had several idigestion type chest pains that include alot of pain in chest an belchin..but nitro tabs relieve it each time. always 2..most of the time only1 needed. but after wards im a little stiff from havin to sit up to reduce the belchin. an they occur while im rested..an come bk randomally..they told me i had angina related to my spasms an that stress also messes with it..but with these attacks..should i fear more serious issues like a heart attack. my last cardiac exam was only weeks ago an was good for someone with my heart issues an blood flow is 40ish...what can make these attacks happen while restin an come bk so much..like once a week or if stressed twice in a week
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....
