For a 60-year-old with known coronary artery disease, the most useful “future ACS attack” plan is not a large medicine kit, but an emergency action plan written by their cardiologist.
-
Aspirin
- Keep plain, non-enteric-coated aspirin available.
- For suspected heart-attack symptoms, many emergency plans use 162-325 mg chewed immediately, if the patient has been told it is safe and has no aspirin allergy, active major bleeding, or prior medical instruction to avoid it.
- Call the local emergency number first or while taking it. Do not drive yourself to hospital.
-
Sublingual nitroglycerin 0.4 mg tablet or spray
- Keep it only if specifically prescribed for angina.
- Typical emergency use: 1 dose under the tongue; repeat every 5 minutes up to 3 doses while awaiting emergency services.
- Do not use if systolic BP is low, there is severe dizziness/fainting, or phosphodiesterase-5 erectile-dysfunction medication was used recently: sildenafil/vardenafil within 24 hours, tadalafil within 48 hours.
- If chest pain persists after the first dose or returns, treat it as an emergency. The current ACS guideline lists 0.3-0.4 mg SL every 5 minutes, up to 3 doses, only in hemodynamically stable people with SBP at least 90 mm Hg. 2025 ACS guideline
-
Their prescribed daily secondary-prevention medicines
Keep an up-to-date supply and do not stop them without cardiology advice:
- Antiplatelet therapy: aspirin and, if prescribed after stenting/ACS, clopidogrel, ticagrelor, or prasugrel
- High-intensity statin
- Beta-blocker, ACE inhibitor/ARB, and other cardiac medicines if prescribed
- Diabetes and blood-pressure medicines
These choices depend on ECG findings, bleeding risk, kidney function, current antiplatelet therapy, and whether urgent angioplasty is planned. The
ACC/AHA ACS update emphasizes clinician-directed antiplatelet treatment and secondary prevention.
The cardiologist should provide a personalized written “chest-pain action plan,” especially if the person has prior bleeding, aspirin allergy, low blood pressure, kidney disease, uses anticoagulants, or takes erectile-dysfunction drugs.
