Signs & Symptoms Suggestive of Cardiovascular/Metabolic/Renal Disease

ACSM identifies a set of major signs or symptoms that may indicate underlying cardiovascular, metabolic, or renal (CMR) disease. Their presence (at rest or with exertion) is the strongest trigger in the screening algorithm: the person should discontinue exercise and obtain medical evaluation/clearance. None is diagnostic alone, but each warrants professional interpretation.

The classic list:

1. Pain/discomfort in the chest, neck, jaw, arms, or other areas that may be ischemic in origin.
2. Shortness of breath at rest or with mild exertion (dyspnea).
3. Dizziness or syncope (fainting).
4. Orthopnea or paroxysmal nocturnal dyspnea — breathlessness lying flat / waking at night short of breath.
5. Ankle edema — bilateral ankle swelling.
6. Palpitations or tachycardia — awareness of rapid/irregular heartbeat.
7. Intermittent claudication — leg pain/cramping on walking, relieved by rest.
8. Known heart murmur.
9. Unusual fatigue or shortness of breath with usual activities.

Context matters: chest discomfort clearly reproduced by a strained pec is different from exertional chest pressure radiating to the jaw. When in doubt, refer.

• Nine classic major signs/symptoms of CMR disease per ACSM.
• Presence of any → discontinue exercise, seek medical clearance before (re)starting.
• Ischemic-pattern chest pain, exertional dyspnea, syncope, claudication, edema are the highest-concern flags.
• Not diagnostic individually — they trigger referral, not a diagnosis.

• acsm-screening-algorithm — these flags override activity status and intensity.
• contraindications-to-testing — overlapping list for halting/deferring a test.
• medical-clearance — the destination when a flag is present.
