One-liner
This episode provides a comprehensive review of Acute Coronary Syndromes (ACS), detailing the diagnostic differences between Unstable Angina, NSTEMI, and STEMI using EKG and troponins, outlining critical time-sensitive management protocols for reperfusion, and reviewing essential pharmacological therapies.
High-yield summary
- Diagnosis Triad: ACS diagnosis requires correlating symptoms with either elevated cardiac biomarkers (troponins) or specific EKG changes (ST elevation/new LBBB).
- ACS Classification: Unstable Angina (UA) has normal troponins; NSTEMI has elevated troponins but no ST elevation; STEMI involves ST elevation and elevated troponins.
- Reperfusion Timing: The goal for door-to-balloon time in a PCI-capable center is 90 minutes. If transfer to a cath lab takes >2 hours, TPA may be considered (if no contraindications).
- Initial Management Pillars: All patients require dual antiplatelet therapy (Aspirin + P2Y12 inhibitor), anticoagulation (Heparin), and beta-blockers within the first 24 hours.
- High-Risk Indications for PCI: Immediate cath lab evaluation is warranted if the patient is hemodynamically unstable, has mechanical complications (e.g., papillary muscle rupture), or fails to improve with medical therapy.
Learning objectives
- Differentiate the diagnostic criteria and clinical presentation of Unstable Angina, NSTEMI, and STEMI using EKG and cardiac biomarkers.
- Apply time-sensitive guidelines for reperfusion strategy (PCI vs TPA) based on institutional capability and patient stability.
- Initiate appropriate initial medical management, including dual antiplatelet therapy, anticoagulation, and beta-blockers, within the first 24 hours of ACS onset.
- Recognize and manage acute mechanical complications of MI, such as papillary muscle rupture or ventricular septal defects (VSD).
- Identify absolute contraindications for thrombolytic agents (TPA) to prevent catastrophic bleeding events.
