Why does angina cause chest tightness?

Reduced flow through the coronary arteries can leave the heart muscle without enough oxygen for its workload. Rather than a sharp pain, many people describe a band-like pressure, heaviness, squeezing, fullness, or tightness. The feeling may spread to the arms, shoulders, jaw, neck, back, or upper abdomen. Chest Tightness is a very common presentation of Angina.

Symptoms often follow exertion or another situation that increases cardiac work, and may settle with rest. A change in the usual pattern matters: tighter, more frequent, longer-lasting, or resting symptoms need prompt medical attention.

Stop what you are doing, rest in a comfortable position, and use glyceryl trinitrate only as prescribed by your clinician. Follow your personal angina action plan if you have one. Do not try to push through chest tightness during exercise or exertion.

Note the circumstances, sensation, duration, and any associated breathlessness, sweating, nausea, or dizziness. Bring this record to your clinician, as it can help show whether the pattern is changing.

Call emergency services for sudden or severe chest tightness, symptoms at rest, tightness that differs from your usual angina, or discomfort that does not settle with the plan prescribed for you. Seek emergency help as well for shortness of breath, faintness, cold sweating, nausea, confusion, or collapse.

Ask what your typical warning symptoms are, whether your medication plan needs updating, and how to use glyceryl trinitrate safely. Discuss activity, travel, dietary triggers, smoking, blood pressure, cholesterol, diabetes, and any testing or cardiology referral that may be relevant to your care.
