What's with the sudden pain in my heart?

Sudden chest pain may be related to reflux esophagitis, costal cartilage inflammation, angina pectoris and other causes.

1. Reflux esophagitis

Reflux esophagitis is an inflammation caused by acid reflux to the esophagus, stimulating the esophageal mucosa. When acid reflux to the esophagus, it will stimulate the esophageal mucosa nerves, which may lead to pain in the heart.

2. Costal cartilage

Costal cartilage inflammation is a non-specific inflammation, occurring at the junction of costal cartilage and sternum. When the inflammation is severe, the pain may spread to the chest area, resulting in pain in the heart.

3. Angina pectoris

When myocardial ischemia occurs, myocardial cells will be damaged, which may cause necrosis, affecting blood supply to the heart, and then induce angina pectoris, resulting in chest pain or pain in the heart.
