Dynamic assessment of left ventricular coupling and myocardial reserve in patients with cardiogenic shock.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aims: Pulmonary artery catheter haemodynamics are associated with improved survival in cardiogenic shock (CS). We investigated the utility of aortic pulsatility index (API) and cardiac power output (CPO) as surrogates for left ventricular (LV) coupling and myocardial reserve, respectively, in patients with CS undergoing dynamic assessment after a milrinone bolus. Methods and results: Patients with SCAI Stage C CS underwent a milrinone drug study (50 mcg/kg bolus infused over 10 min) to assess inotropic response. Haemodynamic measurements were obtained at baseline and following the bolus. Aortic pulsatility index and CPO were used to risk-stratify patients with the incidence of LV assist device (LVAD), orthotopic heart transplantation (OHT), or death at 1 year as the primary composite endpoint. Two hundred and twenty-four patients in SCAI Stage C CS underwent haemodynamics prior to milrinone bolus, and 117 patients had low baseline API < 1.45. Of the 117 patients, 88 had a final API < 2.2 after milrinone load, consistent with LV decoupling, in which 73% met the composite endpoint. The remaining 29 patients had a final API ≥ 2.2 consistent with LV recoupling, and only 55% met the composite endpoint ( Conclusion: The use of API and CPO in a dynamic assessment after provocative testing led to improved risk stratification in patients with SCAI Stage C CS for clinical outcomes including LVAD, OHT, or death at 1 year.
