Angiography also called as CAG is a life saving procedure done for treating patients with heart attack symtoms. It is a cardiac procedure done to examine heart blockages and other cardiac barriers for saving life. The major heart attack symtoms are heavily breathing or shortness of breath (SOB) and pain in the chest. The shortness of breath (SOB) while working is a symtom of heart attack but SOB while at rest is not a symtom of heart attack, it may be related to pulmonary but not to heart. Pain in the chest near retro sternum while working, walkin, and etc is a symtom of heart attack but pain in the chest while sitting, relaxing and etc, could be muscular but not related to heart attack. In Cardiac treatment 3 points should always be cross examined, 1. location of pain in chest, 2. SOB 3. Solbetrate if given to the patient and patient is relieved from pain then the patient is suffering from the heart atack.
