Six intact and seven splenectomized dogs were subjected to a similar degree of hypoxaemia while under light anaesthesia and artificial ventilation. In the intact animals, heart rate, cardiac output, myocardial contractility and oxygen consumption were increased as a result of hypoxaemia; oxygen transport was not affected. In the splenectomized animals the changes in cardiac output and myocardial contractility were small, and oxygen availability was decreased.

Individualized blood pressure regulation and acute kidney injury in older patients having major abdominal surgery: a pilot randomized trial.
Int J Surg
January 2025
Department of Anesthesiology, Xiangya Hospital, Central South University, Changsha, Hunan, China.
Background: Acute kidney injury (AKI) is a common postoperative complication, and hypotension may contribute. We therefore tested the primary hypothesis that individualized intraoperative blood pressure regulation reduces postoperative AKI in older surgical patients.
Methods: We enrolled patients ≥60 years old scheduled for elective major abdominal surgery with invasive arterial pressure monitoring.
Epicardial Adipose Tissue and Left Ventricular Hypertrophy in Hypertensive Patients With Preserved Ejection Fraction: A Multicenter Retrospective Cohort Study.

Department of Radiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Purpose: To investigate fetal cardiac functions and remodeling in pregnancies conceived via in vitro fertilization (IVF).
Methods: This prospective case-control study included 40 singleton IVF pregnancies and 46 uncomplicated control pregnancies at 28-36 weeks of gestation. The IVF group consisted of pregnancies applied to the outpatient clinic, excluding those with anatomical or chromosomal abnormalities.
