Chest Tightness

What is it?

Chest tightness is a high-priority symptom because it overlaps with presentations of acute coronary syndrome (ACS), pulmonary embolism (PE), and other life-threatening conditions. Cardiac tightness is classically described as pressure or squeezing that may radiate to the left arm, jaw, or back, and is associated with exertion, diaphoresis, and shortness of breath. Asthma is the most common cause of recurrent chest tightness in younger patients — wheezing and cough may accompany it. Anxiety and panic attacks cause chest tightness with rapid breathing and palpitations. Costochondritis causes localized, reproducible tenderness at the costochondral junctions. GERD can cause substernal tightness mimicking cardiac pain. Evaluation should always rule out cardiac causes first.

Common causes

When to see a doctor

• 1Chest tightness at rest with diaphoresis, jaw pain, or left arm pain — call 911 immediately
• 2Sudden-onset severe chest tightness with shortness of breath — rule out PE or pneumothorax
• 3Chest tightness in a person with known heart disease or multiple cardiac risk factors
• 4Tightness associated with exertion that relieves with rest — classic angina pattern
• 5Chest tightness with fever and sharp pleuritic pain — possible pericarditis or pleuritis

What you can do

• ✓Do not self-manage new-onset chest tightness without evaluation — rule out cardiac causes first
• ✓Keep rescue inhaler accessible if asthma is the diagnosed cause
• ✓Diaphragmatic breathing exercises help anxiety-related chest tightness and hyperventilation
• ✓Avoid lying flat after meals if GERD is contributing to symptoms
• ✓Eliminate or reduce smoking — a major risk factor for both cardiac and pulmonary causes
