Causes of pulmonary hypertension in ICU | Causes of RV failure in ICU |
---|---|
1) PAH (for example, preexisting PAH; PoPH (8.5% ESLD) | 1) RV Pressure overload, pulmonary hypertension, any cause |
2) Elevated LAP: RV pressure overload (left-sided myocardial infarction/cardiomyopathy; mitral regurgitation; pulmonary stenosis) | 2) Reduced RV contractility |
3) PH due to hypoxia: acute (for example, ARDS)/preexisting lung disease (for example, COPD, IPF) |    RV infarction; sepsis; RV cardiomyopathy; myocarditis; pericardial disease; LVAD; after CPB; after cardiac surgery/transplantation |
4) Thromboembolic (for example, acute PE; chronic (CTEPH); other causes of emboli (AFE, air, cement) | 3) RV-volume overload |
5) Mechanical (for example, increased Pplat - IPPV |    Cardiac causes: tricuspid and pulmonary regurgitation; intracardiac shunts |
