Get a clear starting plan
After a heart attack, new heart-failure diagnosis, valve problem or cardiac procedure, ask your team what activities you can begin and what to avoid. Restrictions depend on your condition and, after a procedure, healing of an incision or access site.
Ask whether you should be referred to cardiac rehabilitation. The team may recommend additional evaluation before you resume exercise.
Progress one step at a time
Once cleared, begin at the level your team recommends. Short, easy sessions may be more manageable than one long effort. Build duration and frequency before increasing intensity. Include a warm-up and cool-down.
Write down how long you were active, how it felt, and any symptoms. Discuss goals such as lifting weights, returning to work, running or competition individually. Recovery timelines are not identical for everyone.
Account for treatment and symptoms
Medicines can change heart rate, blood pressure and fluid balance. Ask how to judge exertion, how to manage heat, and what hydration advice fits your condition. For heart failure, follow your own fluid plan. Carry prescribed rescue medicine and follow its instructions if you have one.
Do not push through symptoms to reach a watch target or a previous training pace. Active heart inflammation, decompensated heart failure, uncontrolled rhythm problems or severe symptomatic valve disease may require exercise to be deferred.
When to stop and get help
Stop activity for chest pressure, significant dizziness, unusual breathlessness or a racing heartbeat with feeling unwell. Call 911 for severe or persistent chest symptoms, fainting or severe breathing difficulty. Contact your team about milder new symptoms before progressing.
