Patients noted the changing nature of the pain that occurs when physical or neuro-psychological stress, and preparations containing nitroglycerin (a substance that dilates blood vessels) does not have the desired effect - the pain remains as acute as everand strong as before the treatment.
pain can be compressive or stitching, but its intensity gradually increases with the progression of an attack of myocardial ischemia, which, in the absence of medical care can quickly go to myocardial necrosis.
pain often all localized in the chest, while it may give (radiate) into the left side of the chest, the left arm throughout, and

At the same time, patients may complain of onset of pain in the epigastric region, which is especially true for heart attacks with atypical arrangement of the zone of myocardial necrosis.In these cases it may be wrongly suspected bout of cholecystitis, stomach ulcer, acute pancreatitis.
Very rarely during an attack there may be momentary, almost imperceptible pain relief, shows the development of large necrosis - the pain is reduced while a significant portion of necrosis of the heart muscle.
