The myocardial performance index (MPI) reflects global ventricular function. Chronic hypervolemia and uremia may negatively affect the myocardium of both ventricles. The aims of this study were to investigate how chronic renal failure (CRF) affects biventricular MPI and to determine whether preload reduction by hemodialysis (HD) affects left ventricular MPI (LVMPI) and right ventricular MPI (RVMPI) in CRF. Twenty-one patients with CRF (group 1) were examined 1 hour before and 1 hour after an HD session and 17 healthy control patients (group 2) were examined once by echocardiography. The MPI for each ventricle was calculated as the sum of isovolumic time intervals divided by the ejection time. Before HD, the LVMPI of group 1 was similar to that in group 2 (P>.05), but the RVMPI of group 1 was significantly higher (P=.007). After the HD session, LVMPI and RVMPI remained unchanged (P>.05 for both). The LVMPI and RVMPI were not correlated either before or after HD in group 1 (P>.05 for both), whereas they were correlated in group 2 (r=0.671, P=.003). Chronic renal failure causes isolated RV dysfunction, as reflected by increased RVMPI values. Preload reduction by HD does not affect LVMPI or RVMPI. Patients with CRF also do not exhibit the correlation of LVMPI and RVMPI that is observed in healthy individuals.

Article Synopsis
- The study focused on evaluating fetal cardiac function in cases of twin-to-twin transfusion syndrome (TTTS) using the myocardial performance index (MPI) and considered the impact of different intrauterine treatments.
- Data from 68 TTTS cases were compared to 68 healthy monochorionic diamniotic (MCDA) twins, examining MPI before and after treatments like amnioreduction, fetoscopic laser photocoagulation, and selective reduction.
- Results showed that while recipients had higher MPI values compared to control twins, only fetoscopic laser photocoagulation and selective reduction led to a significant decrease in MPI values post-treatment, suggesting improvements in cardiac function following these interventions.

Objective: To evaluate the effect of positive end-expiratory pressure (PEEP) ventilation on cardiac function in patients with early left ventricular (LV) diastolic dysfunction undergoing laparoscopic radical gastrectomy.
Methods: Patients who underwent laparoscopic radical gastrectomy under elective general anesthesia from July 2021 to February 2022 at the Subei People's Hospital were enrolled [age 60-75 years old, American Society of Anesthesiologists (ASA) grade I-II, and left ventricular ejection fraction (LVEF) > 0.50].

Dept of Cardiology and Nephrology, St. John's Medical College Hospital Bangalore, India.
Objectives: To identify markers of left ventricular dysfunction in chronic kidney disease (CKD) and the effects of diabetes mellitus on them.
Methods: This was a cross sectional study of 200 consecutive chronic kidney disease patients (stage III-V). Echocardiographic assessment of left ventricular function including left ventricular ejection fraction (LVEF), left ventricular mass index (LVMI), left atrial volume, grade of diastolic dysfunction, E/E', left and right ventricular myocardial performance indices (LVMPI, RVMPI) were compared between diabetic and non-diabetic CKD.

Objective: Adenoid or adenotonsillar hypertrophy (AATH) causes upper airway obstruction, leading to cardiovascular complications. This meta-analysis was conducted to evaluate the efficacy of adenoidectomy or adenotonsillectomy (AATE) on the cardiovascular system.
Methods: Using the Cochrane Central Register of Controlled Trials, PubMed, and EMBASE databases, we identified studies involving a comparison of preoperative and postoperative cardiovascular function in children with AATH.
