Ivabradine in the Acute Management of Cardiogenic Shock (IVASHOCK)
Ivabradine in the Acute Management of Cardiogenic Shock - IVASHOCK-a Double-blind Randomized Controlled Trial
Brief Summary:
The IVASHOCK trial investigates whether ivabradine can achieve at least one-class improvement in SCAI cardiogenic shock classification compared to placebo, and evaluates its safety profile in patients with cardiogenic shock (CS).
Primary Objectives:
- To determine whether ivabradine improves SCAI shock classification by at least one class from baseline within 72 hours compared to placebo
- To assess whether ivabradine facilitates earlier weaning from vasoactive and inotropic support compared to placebo
Safety Endpoints:
Adverse events monitored include: sinus node dysfunction, new-onset atrial fibrillation or atrial flutter, atrioventricular block, drug-related hypotension, and ventricular arrhythmia.
Participant Schedule:
Participants will receive ivabradine or placebo orally every 12 hours for 3 days.
Hemodynamic and metabolic assessments will include:
Arterial pH, central venous oxygen saturation (ScvO2), and serum lactate - every 6 hours on Day 1, then every 8 hours on Days 2 and 3 Heart rate, mean arterial pressure (MAP), vasoactive/inotropic support dose, and urine output - measured on the same timeline

실험적: Ivabradine Plus Standard Care
Participants will receive standard treatment for STEMI complicated by cardiogenic shock, including revascularization, guideline-directed medical therapy as clinically appropriate, standardized vasopressor and inotropic support, and mechanical circulatory support when indicated.
Participants will receive ivabradine 5 mg orally twice daily for up to 3 days, with a maximum of six doses.
Study treatment will be discontinued if the heart rate decreases to <72 bpm or a beta-blocker is initiated.

Ivabradine 5mg oral BID for 3 days (6 tablets)

위약 비교기: Matching Placebo Plus Standard Care
Participants will receive the same standard treatment for STEMI complicated by cardiogenic shock, including revascularization, guideline-directed medical therapy as clinically appropriate, standardized vasopressor and inotropic support, and mechanical circulatory support when indicated.
Participants will receive a matching placebo tablet orally twice daily for up to 3 days, with a maximum of six doses.
Study treatment will be discontinued if the heart rate decreases to <72 bpm or a beta-blocker is initiated.

Hierarchical Composite Clinical Recovery at 72 Hours Assessed Using the Win Ratio
기간: 72 hours
|
The primary outcome will be analyzed using a hierarchical win ratio.
Participants will be compared sequentially as follows: (1) greater increase in total shock score from baseline to 72 hours; the score ranges from 0 to 12 and sums four 0-3 components: mean arterial pressure/vasoactive support, mixed venous oxygen saturation, urine output, and arterial lactate, with higher scores indicating better status; (2) less vasoactive/inotropic support at 72 hours, and if the number of agents is equal, the lower total dose; (3) lactate <2 mmol/L; (4) mixed venous oxygen saturation ≥65%; (5) urine output ≥30 mL/hour; and (6) heart rate <100 beats/min without symptomatic bradycardia, high-grade atrioventricular block, or new atrial fibrillation/flutter.
If participants remain equal after all components, the comparison will be a tie.
The effect will be reported as the win ratio (ivabradine wins/placebo wins).
