Impact of increased venous pressure on kidney function and mortality in cardiovascular patients with preserved ejection fraction.
Conclusions: Our study demonstrates that right ventricular preload affects renal function in patients with preserved systolic function and that neither aortic systolic pressure nor left ventricle pressure indices were related to estimated glomerular filtration rate. Furthermore, we demonstrated for the first time that an increased RAP is able to predict a worse prognosis in patients with preserved ejection fraction independently of well-established risk factors, such as blood pressure and SVI.

Right ventricular pressure-volume loop shape and systolic pressure change in pulmonary hypertension
In conclusion, pressure-volume loop shape and RV systolic pressure differential predominately depend on afterload and PAH severity and reflect RV-arterial coupling in PAH.PMID:33655769 | DOI:10.1152/ajplung.00583.2020

Characteristics of Heart Failure With Preserved Ejection Fraction Across the Range of Left Ventricular Ejection Fraction
CONCLUSIONS: Patients with HFpEF in whom LVEF ranged from 50% to 60% demonstrated reduced contractility, impaired ventriculo-arterial coupling, and higher extracellular volume fraction. In contrast, patients with HFpEF and a LVEF >60% demonstrated a hypercontractile state with excessive LV afterload and diminished preload reserve. A LVEF-based stratification of patients with HFpEF identified distinct morphologic and pathophysiologic subphenotypes.PMID:35862208 | DOI:10.1161/CIRCULATIONAHA.122.059280

Systemic blood pressure in severe aortic stenosis: Haemodynamic correlates and long ‐term prognostic impact
ConclusionsIn severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.
