Once a heart attack is confirmed, the patient will be kept on continuous ECG monitoring.
Further treatment is decided after considerable thought and weighing all the options.
Oxygen may be given, though not always. Medicines like Aspirin may be given to thin blood.
An intravenous nitroglycerin infusion may be started. This increases coronary blood flow. Blood clot dissolving medicine like Streptokinase, Urokinase or TPA ( Tissue Plasminogen Activator) may also be given.
Serial ECG tracings indicate how the heart attack is progressing. Blood tests like Troponin or CPk Enzyme help confirm the diagnosis of heart attack.
