Chest pain has many possible causes, all of which deserve medical attention.

Heart-related causes

Examples of heart-related causes of chest pain include:

  • Heart attack. A heart attack is a result of a blood clot that's blocking blood flow to your heart muscle.
  • Angina. Thick plaques can gradually build up on the inner walls of the arteries that carry blood to your heart. These plaques narrow the arteries and restrict the heart's blood supply, particularly during exertion.
  • Aortic dissection. This life-threatening condition involves the main artery leading from your heart — your aorta. If the inner layers of this blood vessel separate, blood will be forced between the layers and can cause the aorta to rupture.
  • Pericarditis. This condition, an inflammation of the sac surrounding your heart, usually causes sharp pain that gets worse when you breathe in or when you lay down.

Digestive causes

Chest pain can be caused by disorders of the digestive system, including:

  • Heartburn. This painful, burning sensation behind your breastbone occurs when stomach acid washes up from your stomach into the esophagus — the tube that connects your throat to your stomach.
  • Swallowing disorders. Disorders of the esophagus can make swallowing difficult and even painful.
  • Gallbladder or pancreas problems. Gallstones or inflammation of your gallbladder or pancreas can cause abdominal pain that radiates to your chest.

Muscle and bone causes

Some types of chest pain are associated with injuries and other problems affecting the structures that make up the chest wall. Examples include:

  • Costochondritis. In this condition, the cartilage of your rib cage, particularly the cartilage that joins your ribs to your breastbone, becomes inflamed and painful.
  • Sore muscles. Chronic pain syndromes, such as fibromyalgia, can produce persistent muscle-related chest pain.
  • Injured ribs. A bruised or broken rib can cause chest pain.

Lung-related causes

Many lung disorders can cause chest pain, including:

  • Pulmonary embolism. This cause of chest pain occurs when a blood clot becomes lodged in a lung (pulmonary) artery, blocking blood flow to lung tissue.
  • Pleurisy. If the membrane that covers your lungs becomes inflamed, it can cause chest pain that's made worse when you inhale or cough.
  • Collapsed lung. The chest pain associated with a collapsed lung typically begins suddenly and can last for hours. A collapsed lung occurs when air leaks into the space between the lung and the ribs.
  • Pulmonary hypertension. High blood pressure in the arteries carrying blood to the lungs (pulmonary hypertension) also can produce chest pain.

Other causes

Chest pain can also be caused by:

  • Panic attack. If you have periods of intense fear accompanied by chest pain, rapid heartbeat, rapid breathing, profuse sweating, shortness of breath, nausea, dizziness and a fear of dying, you may be experiencing a panic attack.
  • Shingles. Caused by a reactivation of the chickenpox virus, shingles can produce pain and a band of blisters from your back around to your chest wall.
