The New Walk-In with Chest Tightness on the Treadmill
Walter, 71, joins your community-center senior fitness class after a decade of inactivity. He has hypertension and type 2 diabetes, takes a beta-blocker and metformin, and reports no chest pain at rest. On intake he checks no boxes on your screening form and says he 'feels fine.' During his first supervised walk at 2.5 mph on a flat treadmill, he reports mild mid-chest tightness that resolves within two minutes of stopping. He wants to keep going because he 'doesn't want to fall behind.' His resting BP today was 148/88, and his beta-blocker means his heart rate rose only from 68 to 82 bpm during the walk.
1. How should you interpret and act on the exertional chest tightness, and what does the beta-blocker mean for your monitoring strategy?

Exertional chest tightness that resolves with rest is a classic anginal pattern and is a red flag, not a normal response to deconditioning. Stop the session, keep him seated and monitored, and do not resume exercise today.
The beta-blocker blunts both resting and exercise heart rate, so his modest rise from 68 to 82 bpm underestimates his true cardiovascular effort. Do not use heart rate alone to gauge intensity or safety. Use RPE, talk-test, and symptom monitoring, and treat any chest symptom as significant regardless of how low the heart rate looks.
This is a new symptom requiring medical evaluation before he returns to supervised exercise. Document the event (time, workload, symptom description, resolution), advise him to seek prompt medical assessment, and communicate with his physician. Frame it to Walter as protecting his progress, not excluding him.
2. His resting BP is 148/88. Does that alone stop today's session, and how do you set a return-to-exercise plan once he is cleared?
Read the worked answer
A resting BP of 148/88 is elevated but is not, by itself, an absolute contraindication to light-to-moderate exercise in a stable, asymptomatic client. However, combined with new exertional chest tightness, the session should not continue today; the symptom drives the decision, not the blood pressure alone.
Once he is medically cleared, restart conservatively: begin at a low intensity he can sustain while talking comfortably (roughly RPE 11-13), keep sessions short and progress gradually, and monitor symptoms continuously. Recheck resting BP before each session and hold exercise if it is markedly elevated or he is symptomatic. Because beta-blockade hides heart-rate response, anchor intensity to RPE and the talk test rather than target heart rate zones.
