🫀 Door-to-Balloon Time Urgency Simulator

Patient Arrival — The Clock Starts

Every minute from door counts toward final infarct size.

• Time 0: Target metric (clock reference point)
• EMS / walk-in: Typical arrival mode (placeholder)
• Triage: First action (placeholder)
• ACC/AHA: Guideline focus (placeholder)

Why door time matters

Placeholder: the timer begins at first medical contact.

ECG Diagnosis and Cath Lab Activation

ECG confirms STEMI and triggers the reperfusion team.

• <10 min: ECG goal (placeholder)
• Single call: Activation mode (placeholder)
• ~6 staff: Team size (placeholder)
• STEMI vs NSTEMI: Decision point (placeholder)

Rapid diagnosis pathway

Placeholder: fast ECG reading shortens total delay.

Cath Lab Transfer

Patient transport and prep add unavoidable minutes.

• <30 min: Transfer goal (placeholder)
• Sterile field: Prep tasks (placeholder)
• Radial/femoral: Access site (placeholder)
• Off-hours: Bottleneck risk (placeholder)

Logistics of transfer

Placeholder: streamlined handoff reduces delay.

Balloon Inflation — Reperfusion Achieved

Balloon inflation restores flow and halts damage spread.

• 90 min: Guideline goal (door-to-balloon target)
• <60 min: Ideal time (placeholder)
• PCI balloon/stent: Device (placeholder)
• TIMI 3 flow: Success marker (placeholder)

Reperfusion mechanics

Placeholder: restored flow limits further necrosis.

Time-to-Treatment Outcome Impact

Longer delay means larger infarct and lower survival.

• Inverse: Salvage vs time (placeholder)
• Rises: Mortality vs time (placeholder)
• Declines: LV function (placeholder)
• <90 min: Best outcome (placeholder)

Outcome summary

Placeholder: minutes saved translate into myocardium saved.

Placeholder: every 30-minute delay meaningfully raises mortality.
