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
