Reduced Left Ventricular Global Longitudinal Strain Predicts Prolonged Hospitalization: A Cohort Analysis of Patients Having Aortic Valve Replacement Surgery

Effect of Ciprofol on Left Ventricular Myocardial Strain and Myocardial Work in Children Undergoing Cardiac Surgery: A Single-center Double-blind Randomized Noninferiority Study

OBJECTIVE

The current work was designed to compare the effects of ciprofol and propofol on left ventricular systolic function and myocardial work by noninvasive speckle-tracking echocardiography in children undergoing surgical repair of atrial septal or ventricular septal defects.

DESIGN

A single-center double-blind randomized noninferiority study was conducted.

SETTING

The research occurred at a tertiary care center affiliated with Shanghai Jiao Tong University, China.

PARTICIPANTS

One hundred and twelve children aged 1 month to 16 years undergoing atrial septal or ventricular septal defect surgery with cardiopulmonary bypass were included.

INTERVENTIONS

One hundred and twelve children were allocated randomly to receive ciprofol (n = 67) or propofol (n = 45) in a 1.5:1 ratio. Ciprofol or propofol were intravenously infused at loading doses of 0.4 mg/kg or 2.0 mg/kg, respectively, over 30 seconds, depending on the physical condition of each patient. When the bispectral index was maintained between 45 and 55 after induction, transthoracic echocardiography, including apical two-chamber, three-chamber, and four-chamber views, were collected bedside.

MEASUREMENTS AND MAIN RESULTS

Of the 112 patients enrolled, 104 completed the study. Global longitudinal strain in the ciprofol and propofol groups after anesthesia was -17.3% (95% confidence interval [CI] -18.0% to -16.6%) and -17.8% (95% CI -18.7 to -17.0%) in the full analysis set and -17.5% (95% CI -18.2% to -16.9%) and -17.8% (95% CI -18.7% to -17.0%) in the per-protocol set, respectively. The noninferiority margin was set at 2% and confirmed with a lower limit of two-sided 95% CI for the intergroup difference of 1.58% in the full analysis set and 1.34% in the per-protocol set. There were no significant differences between the groups in left ventricular systolic and diastolic function and myocardial work indices. Postoperative vasoactive-inotropic score, NT-proBNP, duration of mechanical ventilation, and the length of stay in the cardiac intensive care unit and hospital were also comparable between the two groups (all p > 0.05).

CONCLUSIONS

Ciprofol did not show different effects on myocardial function and postoperative outcomes from propofol. Further, on the sensitive cardiac systole marker global longitudinal strain, ciprofol demonstrated noninferiority to propofol. Ciprofol might be an alternative solution for cardiac anesthesia in children with congestive heart disease with mild lesion.

Perioperative echocardiographic strain analysis: what anesthesiologists should know

PURPOSE

Echocardiographic strain analysis by speckle tracking allows assessment of myocardial deformation during the cardiac cycle. Its clinical applications have significantly expanded over the last two decades as a sensitive marker of myocardial dysfunction with important diagnostic and prognostic values. Strain analysis has the potential to become a routine part of the perioperative echocardiographic examination for most anesthesiologist-echocardiographers but its exact role in the perioperative setting is still being defined.

CLINICAL FEATURES

This clinical report reviews the principles underlying strain analysis and describes its main clinical uses pertinent to the field of anesthesiology and perioperative medicine. Strain for assessment of left and right ventricular function as well as atrial strain is described. We also discuss the potential role of strain to aid in perioperative risk stratification, surgical patient selection in cardiac surgery, and guidance of anesthetic monitor choice and clinical decision-making in the perioperative period.

CONCLUSION

Echocardiographic strain analysis is a powerful tool that allows seeing what conventional 2D imaging sometimes fails to reveal. It often provides pathophysiologic insight into various cardiac diseases at an early stage. Strain analysis is readily feasible and reproducible thanks to the use of highly automated software platforms. This technique shows promising potential to become a valuable tool in the arsenal of the anesthesiologist-echocardiographer and aid in perioperative risk-stratification and clinical decision-making.

Prognostic Value of Left Ventricular Global Longitudinal Strain for Major Adverse Cardiovascular Events in Patients with Aortic Valve Disease: A Meta-Analysis

INTRODUCTION

Valvular heart disease is one of the most common heart diseases. It is characterized by abnormal function or structure of the heart valves. There may be no clinical symptoms in the early stages. Clinical symptoms of arrhythmia, heart failure, or thromboembolic events may occur in the late stages of the disease, such as palpitation after activities, breathing difficulties, fatigue, and so on. Aortic valve disease is a major part of valvular heart disease. The main treatment for aortic valve disease is valve replacement or repair surgery, but it is extremely risky. Therefore, a rigorous prognostic assessment is extremely important for patients with aortic valve disease. The global longitudinal strain is an index that describes the deformation capacity of myocardium. There is evidence that it provides a test for systolic dysfunction other than LVEF (left ventricular ejection fraction) and provides additional prognostic information.

METHOD

Search literature published between 2010 and 2023 on relevant platforms and contain the following keywords: "Aortic valve disease," "Aortic stenosis," "Aortic regurgitation," and "longitudinal strain" or "strain." The data is then extracted and collated for analysis.

RESULTS

A total of 15 articles were included. The total population involved in this study was 3,678 individuals. The absolute value of LVGLS was higher in the no-MACE group than in the MACE group in patients with aortic stenosis (Z = 8.10, p < 0.00001), and impaired LVGLS was a risk factor for MACE in patients with aortic stenosis (HR = 1.14, p < 0.00001, 95% CI: 1.08-1.20). There was also a correlation between impaired LVGLS and aortic valve surgery in patients with aortic valve disease (HR = 1.16, p < 0.0001, 95% CI: 1.08-1.25) or patients with aortic valve regurgitation (HR = 1.21, p = 0.0004, 95% CI: 1.09-1.34). We also found that impaired LVGLS had no significant association between LVGLS and mortality during the period of follow-up in patients with aortic valve stenosis (HR = 1.08, 95% CI: 0.94-1.25, p = 0.28), but it was associated with mortality in studies of prospective analyses (HR = 1.34, 95% CI: 1.02-1.75, p = 0.04).

CONCLUSIONS

Impaired LVGLS correlates with major adverse cardiovascular events in patients with aortic valve disease, and it has predictive value for the prognosis of patients with aortic valve disease.

Post-cardiopulmonary bypass longitudinal strain provides higher prognostic ability than baseline strain or change in strain

CONTEXT

Global longitudinal strain (GLS) measured by speckle-tracking echocardiography demonstrates excellent prognostic ability in predicting major adverse cardiac events after cardiac surgery. However, the optimal timing of intraoperative GLS measurement that provides the best prognostic value is unclear.

AIM

Our goal was to evaluate whether GLS measured prior to cardiopulmonary bypass (pre-CPB GLS), following CPB (post-CPB GLS), or change in GLS provides the strongest association with postoperative complications.

SETTING AND DESIGN

Post hoc analysis of prospectively collected data from a clinical trial (NCT01187329). 72 patients with aortic stenosis undergoing elective AVR ± coronary artery bypass grafting between January 2011 and August 2013.

MATERIAL AND METHODS

Myocardial deformation analysis from standardized transesophageal echocardiographic examinations were performed after anesthetic induction and chest closure. We evaluated the association between pre-CPB GLS, post-CPB GLS, and change in GLS (percent change from pre-CPB baseline) with postoperative atrial fibrillation and hospitalization >7 days. The association of post-CPB GLS with duration of mechanical ventilation, N-terminal pro-BNP (NT-proBNP) and troponin T were also assessed.

STATISTICAL ANALYSIS

Multivariable logistic regression.

RESULTS

Risk-adjusted odds (OR[97.5%CI] of prolonged hospitalization increased an estimated 27% (1.27[1.01 to 1.59];P_adj =0.035) per 1% decrease in absolute post-CPB GLS. Mean[98.3%CI] NT-proBNP increased 98.4[20 to 177]pg/mL; P_adj =0.008), per 1% decrease in post-CPB GLS. Pre-CPB GLS or change in GLS were not associated with any outcomes.

CONCLUSIONS

Post-CPB GLS provides the best prognostic value in predicting postoperative outcomes. Measuring post-CPB GLS may improve risk stratification and assist in future study design and patient outcome research.

Left ventricular global longitudinal strain and cardiac surgical outcomes

Global longitudinal strain (GLS) has emerged as a valuable diagnostic and prognostic tool for evaluating left ventricular (LV) function. GLS has been shown to be a more sensitive marker of LV dysfunction than LV ejection fraction alone and have prognostic impact in non-surgical cardiac populations. GLS, is validated, reproducible, and easily obtained from 2-dimensional speckle-tracking echocardiography. While there is strong evidence for using GLS in clinical decision-making in non-surgical populations, there is less summarized evidence on using GLS in the cardiac surgical population. This review combines the evidence on the implications of using baseline transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) GLS in cardiac surgical populations including ischemic and structural heart disease to determine surgical outcomes. We found that results seem promising on the prognostic utility of LV strain in cardiac surgical populations. However due to the variability of study populations and outcomes, and modalities (TTE versus TEE), further research on normal versus abnormal values for different surgical populations, as well potential treatment options that may modify and potentially decrease surgical risk for those with abnormal GLS are needed.

Cardiac function in pemphigus vulgaris patients before and after steroid pulse therapy

BACKGROUND

Pemphigus vulgaris which is an autoimmune dermatological disorder characterized by vesiculobullous lesions over the skin and mucosae may also give rise to cardiac disease. Global Longitudinal Strain (GLS) measurement may help to predict cardiac dysfunction in these patients.

METHOD

In this prospective study, the GLS was measured before and after steroid pulse therapy in pemphigus vulgaris patients using 2 D speckle-tracking echocardiography. Moreover, blood pressure, pulse rate, and corrected QT (cQT) interval were recorded before and after steroid pulse therapy.

RESULTS

We included 23 pemphigus patients. The mean age of patients was 34.5(±6.4). Mean GLS decreased significantly after the administration of steroid pulse therapy. The mean GLS decreased regardless of age, however, the patients with the age range of 40-50 years showed the highest change in GLS. There was no interaction between gender and GLS change. Mean cQT increased significantly after pulse therapy (p=.007). Heart rate increased significantly from 88.5 ± 10.8 to 97.0 ± 13.4 (p<.001). Mean systolic and diastolic blood pressure did not show any significant change.

CONCLUSIONS

The steroid pulse therapy may associate with the progression of cardiac dysfunction in pemphigus patients. GLS, as a predictor, may be a valuable marker of cardiac subclinical dysfunction in this condition.

A Comparison of Global Longitudinal, Circumferential, and Radial Strain to Predict Outcomes After Cardiac Surgery

OBJECTIVE

Myocardial strain measured by speckle-tracking echocardiography detects subtle regional and global left ventricular dysfunction. Myocardial strain is measured in the longitudinal, circumferential, and radial dimensions; however, it is unclear which dimension of strain is the best predictor of postoperative outcomes.

DESIGN

A secondary analysis of prospectively collected data from a clinical trial (NCT01187329).

SETTING

The cardiothoracic surgical operating rooms of an academic tertiary-care center.

PARTICIPANTS

Cardiothoracic surgery patients with aortic stenosis having aortic valve replacement (AVR) with or without coronary artery bypass grafting enrolled in a clinical trial.

INTERVENTIONS

Myocardial deformation analysis from standardized investigative transesophageal echocardiographic examinations performed after induction of anesthesia.

MEASUREMENTS AND MAIN RESULTS

The authors compared the ability of intraoperative global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) strain to predict adverse postoperative outcomes, including prolonged hospitalization and the need for pharmacologic hemodynamic support after cardiac surgery. The association of GLS, GCS, and GRS with prolonged hospitalization (>7 days) and the need for pharmacologic hemodynamic support, with epinephrine or norepinephrine after cardiopulmonary bypass, were assessed using separate multivariable logistic regression models with adjustment for multiple comparisons. Of 100 patients, 86 had acceptable measurements for GLS analysis, 73 for GCS, and 72 for GRS. Worse GLS was associated with prolonged hospitalization [odds ratio [OR] (98.3% confidence interval [CI]) of 1.21 (1.01-1.46) per-unit worsening in strain (p = 0.01, significance criterion <0.0167)] and the need for inotropic support with epinephrine [OR (99.2% CI) of 1.81 (1.10-2.97) per-unit worsening in strain (p = 0.002, significance criterion <0.0083)], but not norepinephrine. GCS and GRS were not associated with adverse outcomes.

CONCLUSION

GLS, but not GCS or GRS, predicts prolonged hospitalization and the requirement for inotropic support with epinephrine after AVR.
