Echocardiography-derived stroke volume index is associated with adverse in- hospital outcomes in intermediate-risk acute pulmonary embolism: A retrospective cohort study

SO FUCKING WHAT? Describing a problem with no provided solution or even a way to solve it is a fireable offense in my book.  Some stroke leader needs to lay down the law on stroke research requirements. 

1. Protocols are created with efficacy ratings for every intervention.

2. 100% recovery for all is the goal of all stroke research.

3. No survivor is left behind.

4. Distribution of protocols to every stroke doctor and hospital is required, OR  you distribute them to every 10 million yearly survivors every year from now on.

Echocardiography-derived stroke volume index is associated with adverse in- hospital outcomes in intermediate-risk acute pulmonary embolism: A retrospective cohort study

Chest — Prosperi-Porta G, et al. | April 06, 2020

This study was undertaken to investigate the association between echocardiography-derived stroke volume index (SVI) and death or cardiopulmonary decompensation in intermediate-risk patients with pulmonary embolism (PE).(How are these deaths preventable?) Echocardiographic-derived variables involving SVI were retrospectively examined in normotensive individuals with acute pulmonary embolism admitted between January 2012 and March 2017. Applying the Doppler velocity-time integral in the left or right ventricular outflow tract,  SVI was ascertained. The primary endpoint included in-hospital PE-related death or cardiopulmonary decompensation. A logistic regression was applied to ascertain the relationship between SVI and outcomes, and receiver operating characteristic analysis to compare the performance of SVI and other echocardiographic measures. Association was found between low SVI and in-hospital death or cardiopulmonary decompensation in acute PE. This study found excellent performance of SVJ in comparison with other clinical and echocardiographic variables.
