Scope
Treat ongoing ischaemic chest discomfort or an equivalent syndrome as acute coronary syndrome and activate ambulance and receiving-hospital pathways promptly. Obtain serial ECGs and cardiac troponin under the acute protocol; one normal ECG or early biomarker does not exclude myocardial infarction. This summary is limited to the population, decisions and escalation boundaries stated in the named source.
The Bottom Line
- Treat ongoing ischaemic chest discomfort or an equivalent syndrome as acute coronary syndrome and activate ambulance and receiving-hospital pathways promptly.
- Obtain serial ECGs and cardiac troponin under the acute protocol; one normal ECG or early biomarker does not exclude myocardial infarction.
- Consider spontaneous coronary artery dissection in younger or peripartum patients and avoid assuming conventional atherosclerosis.
- Give immediate antiplatelet and anti-ischaemic treatment only under the Australian emergency protocol after allergy, bleeding and alternative-diagnosis checks.
Practical clinical workflow
1
Topic-specific assessment action
Treat ongoing ischaemic chest discomfort or an equivalent syndrome as acute coronary syndrome and activate ambulance and receiving-hospital pathways promptly.
2
Topic-specific diagnostic action
Give immediate antiplatelet and anti-ischaemic treatment only under the Australian emergency protocol after allergy, bleeding and alternative-diagnosis checks.
3
Topic-specific management action
Use validated risk assessment to guide invasive strategy and monitoring, while recognizing shock, arrhythmia and heart failure as immediate high-risk features.
4
Topic-specific follow-through
Kidney disease and older frailty alter bleeding and contrast risk but should prompt individualized invasive decisions rather than automatic undertreatment.
Safety boundaries and escalation
- At discharge, reconcile dual antiplatelet duration, statin and cardioprotective therapy, cardiac rehabilitation, driving and rapid follow-up responsibilities.
- Clarify duration and interruption rules for antiplatelet therapy before dental or surgical procedures with the cardiology team.
Implementation
The named source is national or binational guidance used in Australia, but referral access, public-health directions, formularies and funded services can still differ by state, territory and health service. Check current TGA product information for medicines. Offer culturally safe care and use the NACCHO鈥揜ACGP National Guide where Aboriginal and Torres Strait Islander preventive or chronic-care recommendations differ.
Clinical use boundary
This independently written summary is not an official guideline. Check the linked source version, current TGA-approved product information where medicines are involved, and the applicable state, territory and local pathway at the point of care.
