Echocardiographic Evaluation of Longitudinal Function in the Left Ventricle Among Critically Ill Patients
Overview
This study evaluates the clinical utility of global longitudinal strain (GLS), mitral annular plane systolic excursion (MAPSE), and tissue Doppler-derived systolic velocity (S') in critically ill patients. These parameters provide assessments of left ventricular function compared to traditional measures like left ventricular ejection fraction (LVEF).
Background
Left ventricular ejection fraction (LVEF) is commonly used to assess systolic function, but its reliability in critically ill patients is limited due to variability and dependence on loading conditions. Alternative measures such as GLS, MAPSE, and S' may offer more consistent evaluations.
Data Highlights
No specific numerical data or trial results were provided in the source material.
Key Findings
GLS has been associated with increased mortality in patients with sepsis and COVID-19.
MAPSE and S' are simpler to acquire than GLS and have been linked to adverse outcomes.
The study aimed to assess the feasibility and prognostic value of GLS, MAPSE, and S' in a heterogeneous cohort of critically ill patients.
Conventional measures of systolic function, such as LVEF, may not be as applicable in the ICU setting.
The PRICES consensus statement recommends the reporting of GLS, MAPSE, and S' in critical care echocardiography studies.
Clinical Implications
GLS, MAPSE, and S' are important parameters for evaluating left ventricular function in critically ill patients.
Conclusion
The study highlights the potential of GLS, MAPSE, and S' as alternative measures of left ventricular function in critically ill patients.
For decades, open-heart surgery was the only treatment option for people with severe aortic valve disease. Patients too sick to withstand major surgery often faced a steady decline in heart function.
In a pooled analysis of two randomized crossover trials, reducing nightly sleep by about 1.5 hours for 6 weeks was associated with modest increases in body weight and waist circumference without measurable changes in body composition.
