Patient : John Coates Facility : HCA Florida Largo Hospital Index Event : 25 May 2025 (Memorial‑Day weekend)
Purpose
Provide a clear, time‑stamped reconstruction of events demonstrating that Mr Coates met “very‑high‑risk NSTEMI” criteria under current ESC (2023) and ACC/AHA (2021) guidelines and therefore should have undergone coronary angiography (and PCI if indicated) within 2 hours of the first diagnostic troponin rise—but instead waited > 24 hours.
This document is intended for the treating team, hospital quality/risk‑management, and any external reviewers.
Key Guideline Triggers
| Guideline | Very‑High‑Risk Criteria (selected) | Recommended Time to Angiography |
|---|---|---|
| ESC 2023 NSTE‑ACS §7.3.1 | • Dynamic hs‑troponin rise/fall and | |
| • Haemodynamic instability (syncope, near‑syncope, shock) or life‑threatening arrhythmia | < 2 h (“immediate invasive strategy”) | |
| ACC/AHA 2021 Chest‑Pain Pathway | Same criteria + GRACE > 140 | < 2 h |
| High‑Risk (no instability) | Dynamic hs‑troponin rise/fall alone | < 24 h |
Mr Coates satisfied both dynamic‐troponin and haemodynamic‑instability criteria → < 2 h target.
Chronological Timeline (25 May 2025)
| Clock Time (ED/Hospital) | Objective Data (chart) | Physiological Interpretation | Patient‑Reported Symptoms |
| ≈ 05 : 45 | Arrival via EMS; triage vitals | Culprit plaque intermittently occluding | First “paralysis” while being moved from EMS stretcher—arms would not lift; speech difficult |
| 06 : 01 | Baseline labs: hs‑troponin‑I 14 ng/L (within reference) | No myocardial necrosis yet | Weak but responsive |
| 06 : 31 – 06 : 40 | CT‑Angio head/neck (+IV contrast) | Stroke work‑up begins | Able to cooperate at start |
| ≈ 07 : 00 | — | Likely complete occlusion of culprit artery | Sudden whole‑body heaviness, vision darkens |
| 07 : 13 – 07 : 16 | CT head (non‑contrast) & “unspecified body region” CT | Patient supine in scanner | Second paralysis + aphasia; teledoctor witnessed failed arm‑lift |
| 07 : 32 | hs‑troponin‑I 248 ng/L (↑ > 7× ULN, > 20 % rise) → Critical High auto‑page | Diagnostic for acute MI; meets very‑high‑risk criteria | Spell slowly resolving when semi‑upright |
| 09 : 04 | Portable CXR | — | Resting in bed; no PCI yet |
| 10 : 39 | MRI brain – no acute infarct | Proves neuro deficits were transient hypoperfusion | Severe fatigue, no new paralysis |
| 13 : 02 | hs‑troponin‑I 2 764 ng/L (≈11× rise since 07 : 32) | Large infarct nearly complete | Chest discomfort easing, exhaustion |
| 20 : 18 | hs‑troponin‑I 2 687 ng/L | Plateau → necrosis ended | — |
| > 07 : 32 (26 May) | Still awaiting cath per chart | < 2 h and < 24 h windows both missed | — |
Departure from Standard of Care
- Guideline breach: 07 : 32 troponin surge + documented haemodynamic collapse required angiography by 09 : 32.
- Delay: No coronary angiography within 24 h; procedure reportedly deferred until 27 May (> 48 h).
- Incomplete bridge therapy (per MAR 25 May): Aspirin and heparin drip started; no documented P2Y₁₂‑inhibitor load, high‑dose statin, or β‑blocker during the first 12 h.
- Additional contrast exposure: Two CT studies with iodinated dye (≈ 100 mL) administered to a single‑kidney patient before coronary angiography—without documented kidney‑protection protocol.
Clinical Impact (to be confirmed)
- Potentially avoidable infarct size: 6‑hour gap between diagnostic spike and peak troponin allowed continued myocyte loss.
- Left‑ventricular function: Pending echocardiogram; any reduction in EF may be partially attributable to delay.
- Future risk: Larger infarct size correlates with higher rates of heart failure, arrhythmia, rehospitalisation, and mortality.
Requested Actions / Questions for the Care Team
- Immediate: Schedule coronary angiography with kidney‑sparing, radial, low‑contrast technique today or arrange transfer.
- Bridge medications: Confirm and document times for ticagrelor/clopidogrel load, atorvastatin 80 mg, and β‑blocker.
- Kidney‑protection bundle: IV isotonic hydration rate, contrast type/volume limit, creatinine checks.
- Post‑MI care: Order transthoracic echocardiogram, enrol in cardiac rehab, provide discharge plan.
- Quality review: Provide written explanation for missing both ≤ 2 h and ≤ 24 h invasive‑strategy windows; retain telemetry and telestroke video as part of the case file.
