Frame
SICM = acute reversible LV dysfunction during sepsis (LVEF ↓ ≥10% or new ≤45%); affects 30-60% of severe sepsis; usually reversible at 7-10 d; SSC bundle remains primary scaffold; LV dysfunction modifies fluid + inotrope strategy
SICM phenotype framed
Patient inputs (10)
Older patients higher SICM incidence (40-60% vs 30% younger); slower recovery trajectory; co-existing baseline CV disease confounds attribution
Source identification (urinary, pulmonary, intra-abdominal, line-associated) + severity (qSOFA / SOFA) drives source control + abx choice + prognosis
AKI common in sepsis + drives drug dosing (RRT-modified); cardiorenal physiology if BOTH SICM + AKI
Anchor pre-sepsis LVEF essential to define SICM (≥10% drop) — without prior echo, must consider chronic HFrEF as alternative; absent pre-data → presume SICM if rapid recovery on serial echo
Hour-1 lactate per SSC; clearance trend (≥10%/h) tracks resuscitation adequacy + organ perfusion
Troponin elevation in 30-50% of severe sepsis — most are SICM/type-2 MI rather than type-1 (4th UDMI 2018); guides cath need
Elevated baseline in sepsis (cytokines + RV strain) — use trend not absolute; absolute >1800 + new LV dysfunction supports SICM
TTE LVEF + global longitudinal strain (GLS); GLS abnormality (less negative than -16%) detects SICM earlier than LVEF; serial day-1, day-3, day-7 echo to track recovery
Blood cultures × 2 + site-specific cultures + source imaging (CT, US) BEFORE abx if no delay; source control non-negotiable
MAP <65 + lactate ≥2 → SCAI shock screen + early NE; SICM superimposed on septic shock has worst outcome

Auto-drafted A&P note
outpatientSubjective
- Possible entry pathways: Severe sepsis or septic shock + new LVEF drop ≥10% absolute (or new LVEF ≤45%) on echo within 48-72h → SICM pathway; Troponin elevation in sepsis WITHOUT ischemic ECG / regional wall motion abnormalities → likely SICM-related demand/depression (rule out type-2 MI); Global LV hypokinesis (NOT regional) on bedside echo during sepsis — pattern favors SICM over ischemic cardiomyopathy.

Monitoring
Regimen monitoring: - serial echo with LVEF and GLS day 1 day 3 day 7 (track recovery — most resolve at 7-10 d) - serial lactate q2h until clearance (resuscitation adequacy marker) - continuous arterial line MAP (titrate NE to ≥65; higher in chronic HTN) - CVP or dynamic markers PLR SVV (volume responsiveness — FENICE) - serial troponin to distinguish sicm vs type1 MI (downward trend favors SICM) - daily BMP with creatinine for AKI (cardiorenal physiology if both AKI + SICM) - CAM ICU q shift for delirium (ABCDEF bundle) - 90 day outpatient echo to confirm recovery or identify persistent HFrEF Setting (outpatient) monitoring: - 90-d echo, then annual if dysfunction persists - Annual BMP + NT-proBNP if HFrEF persists Follow-up plan: 90-day cardiology echo to determine SICM recovery (most do); if persistent dysfunction → start chronic GDMT (4 pillars per ACC/AHA 2022); if recovered → educate patient on sepsis-prevention + future risk; ID follow-up for source control adequacy + suppressive abx if applicable - Close-out criterion: 90-day re-echo + GDMT decision made Monitoring phase: Continuous SpO2 + ECG + arterial line BP; serial lactate q2h until clearance; serial echo (day 1, day 3, day 7) to track LVEF + GLS recovery; daily CBC + BMP + cultures pending; CAM-ICU for delirium; ABCDEF bundle
Disposition
Current setting: outpatient — Long-term cardiology + ID surveillance; 90-d re-echo to determine SICM recovery vs persistent HFrEF; chronic GDMT initiation if persistent dysfunction; sepsis-prevention bundle Disposition criteria: - Long-term continuation; if SICM recovered + no recurrence → routine PCP; if HFrEF persists → handoff to cardio.hf.core.v1 Escalation triggers (move to higher acuity): - Recurrent sepsis → admission + reassess for source - Persistent or worsening dysfunction at 90 d → advanced HF eval - New AF → CHA2DS2-VASc + AC decision
