my husband 63 years old, has a history of stroke, heart attack, cabg (x3), diabetes, neuropathy and chf. The last couple days he has had blood pressure on the low side 90/54... this morning he also had, left sided chest pain with some belching... I think it is his heart again, symptoms are all to reminiscent of 3 years ago... he won't go of course, what is your thought. Can there be any other reason for the low bp and chest pain. (oh chest pain lasted abot 15-20 mintes)
