What Causes Chest Pain and Nausea Together?

What It Means

When chest pain and nausea occur at the same time, a shared underlying condition is usually responsible. 3 medical conditions are known to produce this symptom combination.

Key Factors

• →Inferior wall STEMI with vagal activation causing nausea
• →NSTEMI with nausea from systemic sympathetic response
• →Pulmonary embolism with low cardiac output and vasovagal nausea
• →Myocarditis or pericarditis with nausea from pericardial inflammation
• →GERD/esophageal spasm (diagnosis of exclusion)

Common Causes

• →Inferior wall STEMI with vagal activation causing nausea
• →NSTEMI with nausea from systemic sympathetic response
• →Pulmonary embolism with low cardiac output and vasovagal nausea
• →Myocarditis or pericarditis with nausea from pericardial inflammation
• →GERD/esophageal spasm (diagnosis of exclusion)

Related Conditions

• GERD (Acid Reflux)Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the esophagus, causing heartburn, regurgitation, and chest discomfort. Long-term untreated GERD can lead to esophageal damage.
• Heart Attack (Myocardial Infarction)A heart attack occurs when blood flow to part of the heart muscle is blocked, usually by a blood clot in a coronary artery. Immediate treatment is critical. Symptoms include chest pain, pressure radiating to the arm or jaw, sweating, and nausea.
• Hypertensive EmergencyA hypertensive emergency is a severe elevation in blood pressure (typically above 180/120 mmHg) with acute end-organ damage, including hypertensive encephalopathy, acute heart failure, acute coronary syndrome, or aortic dissection. It requires immediate blood pressure reduction in an intensive care setting.
