9.2 Hypertension, Dyslipidemia, Post-Cardiac, PVD, and Stroke
Key Takeaways
- Hypertensive clients should avoid the Valsalva maneuver and heavy prolonged isometrics because those tactics spike blood pressure; use rhythmic breathing and dynamic resistance within medical limits.
- A commonly cited ACSM GETP relative contraindication is resting SBP >200 mm Hg and/or DBP >110 mm Hg—do not begin the session and refer; this is an ACSM-style threshold, not an unpublished NSCA-only number.
- Post-cardiac clients train with an NSCA-CPT only after formal cardiac rehabilitation and/or written physician parameters; the CPT is not a cardiac rehab specialist.
- Peripheral vascular disease with claudication is commonly trained with walk-to-moderate-pain, rest until symptoms ease, then repeat, inside physician parameters; rest pain or tissue-loss signs are referral red flags.
- Stroke survivors need fall-risk management, unilateral-deficit modifications, and collaboration with physical therapy; do not independently diagnose stroke sequelae or load an unstable involved shoulder.
Why this cardiovascular family is tested
The public NSCA-CPT special-population outline lists hypertension, hyperlipidemia, post-cardiac rehabilitation, peripheral vascular disease (PVD), and stroke together. Domain 2.B still governs: recognize the condition, identify contraindications, modify only within medical recommendations, refer. You will see items that tempt you to 'just start light' when the correct behavior is to not begin the session—or items that tempt you to write a phase II cardiac rehab plan when the correct behavior is to wait for the physician and the rehab team.
Quick Answer: If resting blood pressure exceeds the ACSM GETP relative-contraindication gate (SBP >200 mm Hg and/or DBP >110 mm Hg), do not start and refer. Hypertensive clients avoid Valsalva and heavy isometrics. Post-cardiac training happens only after formal rehab and physician parameters. PVD uses walk-then-rest claudication protocols. Stroke work is fall-risk and PT collaboration. The CPT is not a cardiac rehab specialist.
Hypertension: breathing, isometrics, and a labeled stop number
Hypertension is a physician diagnosis. The ACC/AHA 2017 adult classification used in current U.S. teaching is ≥130 mm Hg systolic or ≥80 mm Hg diastolic (stage 1 at 130–139 / 80–89; stage 2 at ≥140 or ≥90). That classification tells you the client has high blood pressure as diagnosed in clinic. It is not the same number as the pre-session 'do not begin' gate.
Source-labeled session start rule (do not invent an NSCA-only unpublished number). ACSM's Guidelines for Exercise Testing and Prescription (GETP) lists resting hypertension with systolic BP >200 mm Hg or diastolic BP >110 mm Hg as a relative contraindication to exercise testing. Personal-training instruction commonly applies those same resting values as a do not begin this training session and refer threshold when you measure a seated, resting pre-session blood pressure. Teach it as an ACSM-style GETP safety gate. Do not claim NSCA published a secret different cutoff. Do not confuse it with 130/80 (diagnosis) or with a hypertensive-crisis discussion that belongs to emergency medicine.
A related ACSM testing number, used during a graded test rather than at the start of a gym session, is a relative indication to terminate the effort when SBP is >250 mm Hg or DBP is >115 mm Hg. If a client you are training shows a rapidly climbing hypertensive response, unusual headache, chest pain, or neurologic symptoms, stop, recover, and follow your emergency action plan—do not chase personal records.
Compare the numbers so the exam cannot mix them:
| Number | Role | Source / use |
|---|---|---|
| ≥130 / ≥80 mm Hg | Diagnostic classification of hypertension | ACC/AHA 2017 (physician diagnosis) |
| ≥140 / ≥90 mm Hg | Stage 2 hypertension classification | ACC/AHA 2017 |
| Resting SBP >200 and/or DBP >110 mm Hg | Relative contraindication to exercise testing; commonly taught as do-not-start and refer | ACSM GETP |
| SBP >250 or DBP >115 mm Hg | Relative indication to terminate an exercise test | ACSM GETP |
Valsalva and heavy isometrics. A closed-glottis strain (Valsalva) produces a sharp rise in intrathoracic and arterial pressure. Prolonged high-tension isometrics can do the same. For hypertensive clients, coach exhale on exertion, avoid breath-holding on the sticking point, and prefer dynamic resistance with moderate loads and continuous breathing unless the physician wrote a different plan. Heavy isometric wall-sits-for-time, maximal grip squeezes, or 'see how long you can hold the lockout' are poor default choices. ACSM hypertension programming commonly emphasizes moderate aerobic work on most days (often summarized as about 90–150 minutes per week) plus resistance 2–3 days per week—always inside clearance.
If the client is on a beta blocker, heart rate underestimates intensity. Use rating of perceived exertion and talk-test cues rather than a target heart-rate formula you cannot validate. The CPT does not stop, start, or titrate antihypertensive drugs.
Dyslipidemia (hyperlipidemia)
Dyslipidemia is an abnormal lipid profile (elevated LDL or triglycerides, low HDL, or a combination) diagnosed by a physician. It is not, by itself, a reason to cancel a cleared exercise session. Aerobic and resistance training are generally indicated as part of lifestyle care. Two CPT-level traps:
- Statin-associated muscle symptoms (new unexplained myalgia, weakness, or cramps, especially if bilateral and not explained by delayed-onset soreness from a load you actually programmed). Stop the aggravating work, document, and refer—you do not diagnose rhabdomyolysis from a statin story alone, and you do not tell the client to discontinue the drug.
- Nutrition medical therapy (therapeutic lipid-lowering diets, supplement stacks sold as 'cholesterol cures') is physician/RDN territory. General MyPlate-style education that is already in CPT nutrition scope is fine; a prescribed medical diet is not.
Post-cardiac: after rehab, inside written parameters
Post-cardiac includes myocardial infarction, coronary stent/PCI, CABG, valve surgery, and stable heart-failure clients who have been through (or been assigned to) cardiac rehabilitation. The NSCA-CPT is not a cardiac rehab specialist and does not independently open a phase II monitored program, interpret diagnostic ECGs, or write a target MET load after last week's stent.
Train these clients only after formal cardiac rehab and/or written physician parameters. Those parameters may include a heart-rate ceiling, forbidden movements, sternal precautions (no heavy pushing/pulling or loaded horizontal adduction early after sternotomy), anginal equivalents to stop for, and whether a defibrillator or pacemaker changes range of motion. If the client wants to skip rehab because 'I feel fine' or 'the incision looks good,' you delay fitness-floor training and send them back to the physician/rehab team.
Stop and emergency-refer for chest pain or pressure, unusual dyspnea, syncope or near-syncope, sudden palpitations with distress, or a drop in performance with signs of poor perfusion. Your facility EAP and current CPR/AED credential are the response—not a harder warm-up.
PVD and claudication
Peripheral vascular disease (often discussed as lower-extremity peripheral artery disease) limits blood flow to working muscle. Intermittent claudication is reproducible aching, cramping, or fatigue in the calves (or other muscle groups) that appears with walking and eases with rest.
The commonly taught protocol is: walk until moderate claudication, rest standing or sitting until pain subsides, then repeat, accumulating walking time across the session (often toward 30–50 minutes of total walking, three times per week in supervised programs). As tolerance improves, increase speed or grade so claudication still appears—this is a pain-then-rest training stimulus, not a 'no pain, no gain' sprint through 10/10 ischemic pain. Stay inside physician parameters; many clients belong first in a supervised vascular or cardiac-rehab walking program.
Do not treat all leg pain as claudication you can train through. Rest pain, non-healing ulcers, a suddenly cold/pale/pulseless limb, or neurologic drop-foot stories need referral, not a longer treadmill interval. If chest symptoms appear as walking capacity improves (unmasking coronary disease), stop and follow cardiac emergency rules.
Stroke
Stroke (cerebrovascular accident) can leave unilateral weakness, spasticity, sensory loss, visual-field cuts, aphasia, neglect, and high fall risk. Medical clearance and physical therapy parameters come first. The CPT collaborates; the CPT does not replace the neurologist or the PT.
Practical modifications: guard against falls (stable stance, fewer open-chain high-risk plyometrics, clear floors), load the involved side only as PT allows, watch for glenohumeral subluxation on a flaccid shoulder (do not hang heavy dumbbells from that arm), and prefer demonstration and short cues when aphasia is present. Unilateral deficits change spotting and machine setup. Progress balance and gait only inside the written PT/physician plan.
Exam traps
- 130/80 diagnoses hypertension; >200 / >110 (ACSM GETP) is the commonly cited do-not-start testing/session gate—label the source.
- Valsalva and heavy isometrics are the hypertensive programming errors the exam loves.
- Post-stent or post-MI enthusiasm does not authorize you to replace cardiac rehab.
- Claudication walking is intermittent walk-rest, not all-out pain or complete avoidance of walking when walking is indicated.
- Stroke: fall risk and PT collaboration beat aggressive 'symmetry' loading.
