What should I do now?
Call 911
Call 911 for new or unexplained chest pressure that persists or returns, severe trouble breathing, collapse without normal recovery, or sudden face/arm weakness or trouble speaking. Do not drive yourself.
Contact your care team
Contact your care team for persistent or worsening fatigue or a meaningful decline in your usual activity.
Keep your care plan
Record how symptoms affect daily tasks, and review sleep and medications with your clinician.
SECTION 6
Preparing for your appointment
- Compare what you can do now with what you could do before.
- Record when fatigue began and whether it is worsening.
- Note sleep quality, snoring, or breathing pauses noticed by someone else.
- List breathlessness, chest discomfort, palpitations, swelling, or bleeding.
- Bring medicines and doses, including supplements and recent changes.
Ask which causes are being considered, what activity is safe, and when to reassess. Bring previous heart tests and relevant laboratory results if available.
A specific example—“I now need to stop halfway up the stairs”—can help your clinician understand the change.
