Setting Intensity and Progression After a Recent Stroke in a Patient with Cardiac Comorbidity
A 67-year-old man is 9 days post left middle cerebral artery ischemic stroke. He has right hemiparesis: right hip flexion and knee extension 3/5, right ankle dorsiflexion 2/5, right upper extremity 2/5, with mild neglect on the right and intact communication. He ambulates 10 meters with a hemi-walker and one-person assist, and needs moderate assistance for sit-to-stand. Comorbidities: heart failure with reduced ejection fraction (last EF 30%), atrial fibrillation on apixaban, and type 2 diabetes. Resting HR 88, BP 142/84, SpO2 96% on room air. The family wants him to 'walk as much as possible every day' and asks why he is not doing more. The inpatient team has not yet ordered a cardiac stress evaluation.
1. Identify the factors that constrain exercise intensity and describe how you would monitor and progress him safely.

Constraining factors:
- HFrEF with EF 30% - reduced cardiac reserve; risk of decompensation with high-intensity or prolonged aerobic work; fluid status must be watched.
- Recent stroke (9 days) - early mobilization is beneficial but the patient is still in the acute/subacute phase with hemodynamic lability.
- Atrial fibrillation on apixaban - variable rate response and bleeding risk with falls.
- Diabetes - glycemic variability and fatigue.
- Low functional level - moderate assistance for sit-to-stand means high relative intensity for simple tasks.
Monitoring: pre/post HR, BP, SpO2, and RPE (Borg 11–13); watch for dyspnea, chest pain, dizziness, new arrhythmia symptoms, and excessive fatigue. Use the talk test and stop criteria. Track fluid status (weight, edema).
Progression: start with short bouts (e.g., 5–10 minutes of gait training) with rest breaks, multiple times per day, and progress duration before intensity. Use interval-style training. Do not push to high intensity without medical clearance given EF 30%. Document the response to each session and adjust.
2. The family asks why he is not walking more each day. How do you respond, and what is your recommendation to the team?

Response to the family: explain that more walking is the goal, but that his heart's pumping function is reduced and he is only 9 days from a stroke, so exercise must be built up gradually to avoid fatigue, falls, and cardiac strain. Emphasize that frequent short bouts with rest are safer and often produce more total practice than one long session. Frame the plan as progressive, not restrictive.
Recommendation to the team:
- Request a medical/cardiac risk assessment before advancing to higher-intensity aerobic training, given EF 30% and recent stroke.
- Coordinate with nursing and PT to schedule multiple short mobilization sessions across the day.
- Set objective progression criteria (e.g., stable vitals and RPE ≤13 during 10-minute bouts before increasing).
- Document the rationale so the team and family share the same plan.
Judgment being tested: advocating for early, frequent mobilization while respecting cardiac constraints, and escalating for clearance rather than either over-restricting or over-pushing.
3. Define measurable short-term goals and discharge criteria for this patient.
Read the worked answer
Short-term goals (e.g., 1–2 weeks):
- Sit-to-stand with contact guard or minimal assistance (from moderate assistance) using a standard-height chair.
- Ambulate 30 meters with a hemi-walker and standby assist (from 10 m with one-person assist), with rest breaks as needed.
- Tolerate three 10-minute mobilization sessions per day with stable vitals and RPE ≤13.
- Demonstrate understanding of fall precautions and cardiac warning signs.
Discharge criteria (to next level of care):
- Independent or supervision-level transfers and ambulation for household distances with an appropriate device.
- Safe stair negotiation if home requires it.
- Caregiver trained in assistance and safety.
- Stable physiologic response to activity and no new red flags.
Measurement: use a functional measure (e.g., Berg Balance Scale or 6-minute walk test as tolerated) at baseline and discharge, and document MMT and gait distance each week to show progress objectively.
