  • Chest pain

    serch.it?q=Chest-pain

    Chest pain is pain in any region of the chest. Chest pain may be a symptom of a number of serious disorders and is, in general, considered a medical emergency. Chest pain can be differentiated into heart-related and non heart related chest pain. Cardiac chest pain is called angina pectoris. Some causes of noncardiac chest pain include gastrointestinal, musculoskeletal, or lung issues. Even though chest pain may not be related to a heart problem, noncardiac chest pain can still be due to significant disease. Chest pain can present with different types of pain and associated symptoms which may vary with a person's age, sex, and previous medical conditions. Determining the cause of chest pain is through review of a person's medical history, a physical exam, and other medical tests. Management of chest pain is based on the underlying cause. Chest pain is a common presenting problem: In the United States, an estimated 6-8 million people per year present to the emergency department with chest pain. An estimated 50-70% of patients presenting with chest pain in the emergency department will be placed in an observation unit or admitted to the hospital. 2 million people are admitted annually for workup of acute coronary syndrome. Approximately 8 billion dollars are used annually to evaluate complaints of chest pain. Children with chest pain account for 0.3% to 0.6% of pediatric emergency department visits.
