Article Abstract
Among 90 consecutive patients with various degrees of left ventricular (LV) dysfunction (normal patients, LV hypertrophy, LV ejection fraction <50%, and <30%), the mitral valve pulse-wave E/A ratio showed a characteristic U-shaped curve with increasing severity of LV dysfunction. In contrast, there was a significant progressive decrease in flow propagation velocity of the E-wave (Vp) and a significant increase in E/Vp values with increasing severity of LV dysfunction. The E/Vp ratio was the best predictor of pulmonary congestion, and in a subgroup of patients who underwent cardiac catheterization, it was the only significant predictor of LV end-diastolic pressure.

Background: Echocardiographic reference intervals for Quarter Horses are infrequently reported.
Objectives: To provide standard echocardiographic measurements for sedentary Quarter Horses and evaluate the relationship between physical characteristics (body weight, age, sex) and echocardiographic measurements.
Animals: Forty-one sedentary Quarter Horses, free of cardiac disease, from a university research herd.
Respiratory Stability Time Transition in Acute Decompensated Heart Failure with Reduced Left Ventricular Ejection Fraction.

A novel telemonitoring system utilizing contactless sensor technologies combined with automated overnight respiratory stability time (RST) analysis has emerged as a sensitive and specific indicator of worsening heart failure (HF), enabling early clinical exacerbation identification. However, the correlation between the RST trajectory and other clinical parameters, as well as targeted therapeutic strategies for improving RST in patients experiencing acute decompensated HF, remains unclear. Herein, we present two cases of hospitalized patients with HF and reduced left ventricular ejection fraction, which were successfully managed through clinical interventions monitored by integrated RST parameters.

A left ventricular sub-mitral thrombus without an aneurysm is a previously unreported rare occurrence. We aim to bring attention to this finding in a case of colorectal adenocarcinoma.An early 60s-year-old female presented with bleeding per rectum, weight loss and fatigue and was found to have colorectal carcinoma with metastasis based on examination, imaging and biopsy findings.

Background: The hemodynamic effects of femoro-femoral venoarterial (VA) extracorporeal membrane oxygenation (ECMO) on pulmonary capillary wedge pressure (PCWP) remain poorly defined. High ECMO flow is believed to increase PCWP and the risk of pulmonary edema; yet, supporting in vivo physiological data are lacking.
Objectives: The purpose of this study was to evaluate the impact of incremental femoro-femoral VA-ECMO flow variations on PCWP, hemodynamic, and echocardiographic parameters in patients with cardiogenic shock during the early phase of VA-ECMO support, after stabilization.
Klotho attenuates D-galactose-induced cardiac aging through the ROS/NLRP3/pyroptosis pathway.

Objective: Activation of NLRP3 inflammasome contributes to cardiac aging progression. Klotho, a recognised anti-aging protein, exerts protective effects against cardiac aging. In this study, we aimed to elucidate the protective effects of Klotho on D-galactose (D-gal)-induced cardiac aging and the underlying mechanisms.
