Chest pain can be caused by a variety of illnesses, ranging from benign and self-limiting to significant or life-threatening. Before a doctor examines more benign reasons, a workup must focus on ruling out significant pathology. The words "dull," "deep," "pressure," and "squeezing" are commonly used to describe visceral discomfort. Visceral pain generally has a diffuse distribution pattern, making it difficult for the patient to pinpoint a precise location. chest discomfort accounts for 1.5 percent of all consultations in primary care. The age group 45 to 64 years has the highest prevalence of chest pain consultations. Patients with suspected Acute coronary syndrome (ACS)  should be diagnosed and treated as soon as feasible.
