What to do if…
you notice new chest tightness or pressure that comes and goes

Short answer

Treat new chest tightness/pressure as potentially serious. If it’s happening now, or returns with shortness of breath, sweating, nausea, lightheadedness, or pain spreading to your arm/jaw/back, call 911.

Do not do these things

  • Do not drive yourself to the ER if you think this could be heart-related (EMS can start care sooner).
  • Do not “wait and see” if it’s new, worsening, or keeps returning.
  • Do not exercise, take a hot shower, or try to “prove you’re fine” by pushing through it.
  • Do not take extra medications (including aspirin) before calling 911 to see if it fixes it.
  • Do not assume it’s anxiety/heartburn if it’s unusual for you—especially if you have heart risk factors.

What to do now

  1. Decide if you should call 911 right now. Call 911 if any apply:
    • The tightness/pressure is happening now and lasts more than a few minutes, or it goes away and comes back.
    • It comes with shortness of breath, cold sweat, nausea/vomiting, unusual fatigue, or lightheadedness.
    • The discomfort spreads to one or both arms, back, neck, jaw, or upper stomach area.
    • You feel “not right,” faint, or very unwell—even if the chest feeling is mild.
  2. If you call 911: set yourself up for faster help.
    • Sit and rest; keep activity minimal.
    • Unlock the door, turn on a light, and keep your phone on speaker.
    • Gather: your medication bottles/list, allergies, key conditions, and any recent changes (new meds, recent illness, stimulant use).
  3. Aspirin: follow the 911 operator/clinician’s direction.
    • Call 911 first. The operator may recommend chewing aspirin if it’s appropriate for you (for example, a regular adult aspirin is often 325 mg, but follow the operator’s instructions).
  4. If you have prescribed nitroglycerin: use it only as prescribed.
    • If you were previously instructed to use nitroglycerin for chest pain, take it exactly as directed while waiting for EMS.
  5. If it’s fully settled right now but it’s new/recurrent today: still get same-day urgent evaluation.
    • If symptoms return, or you had any red-flag symptoms (breathlessness, sweating, nausea, lightheadedness, spreading pain), choose the safer option: call 911.
    • If you feel well right now but this is new, seek urgent same-day evaluation as directed by a clinician/triage service (often the Emergency Department for new chest pressure).
  6. Make a quick “episode log” for EMS/clinicians.
    • Start time, duration, what you were doing (rest/exertion), where you felt it, associated symptoms, and what helped (rest, nitro, etc.).
  7. If you’re alone: involve someone.
    • Call/text a trusted person to be on the phone with you or come over, and keep your phone charged and close.

What can wait

  • You do not need to diagnose the cause right now.
  • You do not need to test yourself with stairs/exercise or keep working through it.
  • Don’t spend time on insurance/work/pharmacy logistics or searching online right now—focus on getting urgent assessment safely.

Important reassurance

Many serious heart problems can start with symptoms that come and go. Acting quickly when something is new is a reasonable, protective choice—even if it turns out not to be your heart.

Scope note

These are first steps to keep you safe and get to appropriate urgent care. Next steps (tests, observation, follow-up) depend on what clinicians find.
