Heartburn and angina may have similar symptoms, but it is dangerous to confuse them. We tell you what signs may indicate a cardiac cause of chest pain after eating.

This is stated in the material of the Hungarian medical portal EgészségKalauz.

However, with a significant narrowing of the coronary vessels, the heart muscle may not receive enough blood and oxygen. This causes ischemia, which can be manifested by pain or pressure in the chest — angina pectoris. As the American Heart Association explains, ischemia occurs when the heart muscle does not get enough oxygenated blood.

“With pronounced narrowing of the coronary vessels, certain areas of the heart muscle may not receive enough blood,” says EgészségKalauz.

“The symptoms of reflux and angina can be very similar in some cases,” the publication notes.

According to the Hungarian medical portal EgészségKalauz, angina pain is more often felt as pressure, compression or heaviness in the chest. It can spread to the neck, shoulders, jaw, arms, or back and be accompanied by shortness of breath, nausea, dizziness, and sweating. The publication also notes that sometimes pain occurs in the upper part of the abdomen — the epigastrium, which can be perceived as a digestive disorder.

Context

Pressure, constriction, or heaviness in the chest after an abundant lunch or dinner is often blamed on overeating, heartburn, or reflux. However, sometimes such discomfort can indicate angina, a condition in which the heart muscle temporarily does not receive enough oxygen.

“Complaints are often of a burning nature and can be accompanied by an acid taste in the mouth, an acid burp or an unpleasant sensation in the throat,” explains EgészségKalauz.
