Treatment modalities for chest pain are aimed toward increasing the blood flow through coronary arteries. Chest pain causes an increase in the stimulation of the sympathetic nervous system. This stimulation increases the heart rate and blood pressure, causing an increase in myocardial workload aggravating the chest pain.
