Kabilan K. L.: Management and Diagnosis of Acute Coronary Syndrome Types
Kabilan K. L., Long-Term Care Nurse at Al Emeis Hospital, shared a post on LinkedIn:
”ACS is a group of conditions caused by sudden reduction in blood flow to the heart muscle, resulting in acute myocardial ischemia.
Most commonly due to rupture of an atherosclerotic plaque with thrombus formation.
Classification:
STEMI (ST-Elevation Myocardial Infarction):
- ST-segment elevation on ECG
- Usually complete coronary occlusion
- Elevated cardiac biomarkers
- Requires immediate reperfusion therapy
- NSTE-ACS
- Partial coronary occlusion
- Includes
NSTEMI: Elevated troponins
Unstable Angina: No troponin elevation
Clinical Features:
- Central chest pain/pressure
- Radiation to arm, neck, jaw, or back
- Dyspnea
- Diaphoresis
- Nausea and vomiting
- Palpitations
- Anxiety and dizziness
- Hypotension or cardiogenic shock (severe cases)
Investigations :
- 12-lead ECG
- Cardiac biomarkers (Troponin I/T)
- Echocardiography
- Coronary angiography
Immediate Management:
- Oxygen if hypoxic (SpO₂ <90–94percent)
- Cardiac monitoring
- IV access
- Aspirin 300 mg chewed
- Nitroglycerin (if not contraindicated)
- Analgesia as required
- Early cardiology referral
Reperfusion Strategies (STEMI):
- Primary PCI (preferred)
- Thrombolytic therapy if PCI unavailable within recommended time
- Emergency CABG in selected patients
Pharmacological Therapy:
- Dual antiplatelet therapy (DAPT)
- Anticoagulants
- Nitrates
- Beta-blockers
- ACE inhibitors/ARBs
- Statins
- Glycoprotein IIb/IIIa inhibitors (selected cases)
Key Point:
Time is myocardium. Early recognition, rapid diagnosis, and prompt reperfusion significantly improve survival and outcomes.”
