Posterior Wall STEMI & Associated Complications 1. Posterior Wall STEMI: Anatomical & Diagnostic Overview Affected Coronary Anatomy: Left Circumflex Artery (LCx): Primary occlusion site in 15–20% of cases, often linked to lateral-posterior ischemia. Posterior Descending Artery (PDA): Typically involved in inferior-posterior infarcts (right coronary dominance). Diagnostic Challenges: Subtle ECG findings (e.g., ST-segment depression in V1–V3, upright T-waves). Confirm with posterior leads (V7–V9).

Exploring Posterior and Septal STEMI: Posterior STEMI: Posterior STEMI often accompanies inferior or lateral infarctions and can be tricky to diagnose due to its subtle presentation on a standard 12-lead ECG. Key indicators include: - Standard 12-lead ECG: Look for ST-segment depression in the anteroseptal leads (V1-V3). - Posterior Leads (V7-V9): Confirm with ST-segment elevation in these leads. - Clinical Features: May include **hypokinesis and akinesis in the posterior segments of the left ve
