thanks for writing to us.
it is not uncommon to feel unwell early after an heart attack
, as your body is adjusting to not only the changes brought about by heart attack but also to the effects of so many medications. i did not get what you meant by erratic breathing ? Persistent white cold hand and feet is a problem but if it comes and goes, it has to be examined and then only something can be surely said. however if you have difficult in breathing, chest heaviness, chest discomfort
, shortness of breath
, excessive sweating
, vomiting, severe palpitation
, blackout please see your physician on urgent basis.
