Does the PEACE score accurately predict abnormal echocardiographic findings and survival in patients with acute pulmonary embolism?
The PEACE score is a highly effective tool for rapid risk stratification in emergency department patients with acute pulmonary embolism, accurately predicting right ventricular dysfunction and mortality.
Effect estimate: AUC 0.82 (95% CI 0.74-0.90)
p-value: p=<0.001
BACKGROUND: Pulmonary embolism (PE) is a life-threatening condition requiring rapid risk stratification for optimal management. The Pulmonary Embolism Advanced Cardiac Evaluation (PEACE) Score is a novel tool integrating clinical, laboratory, and echocardiographic parameters to assess disease severity. This study aimed to evaluate the correlation between PEACE Score and echocardiographic abnormalities in PE patients, and to determine its effectiveness as a rapid risk assessment tool in emergency settings. METHODS: Between June 2020 and June 2024, 120 patients were prospectively screened and enrolled in the study after being diagnosed with pulmonary embolism via CT angiography in the emergency department. Patients were categorized into three groups according to PEACE score as low risk ( 5 points, n = 26). Echocardiographic findings were not used for stratification but rather analyzed as outcome variables to assess the discriminative validity of the PEACE Score. Demographic data, laboratory findings and echocardiographic parameters were recorded. Patients were followed up for at least 1 year. Follow-up from 3 months to 6 months was evaluated and mortality rates at the end of 1 year were determined. RESULTS: PEACE Score was strongly correlated with echocardiographic abnormalities (r = 0.685, p 5 points showed a sensitivity of 84.6% and specificity of 79.2% for detecting severe echocardiographic abnormalities. One-year survival rates were 45% in the high-risk group, 65% in the intermediate-risk group, and 85% in the low-risk group. Kaplan-Meier analysis confirmed significant differences in survival among risk groups (p < 0.001). CONCLUSION: The PEACE Score demonstrated a strong association with echocardiographic abnormalities and patient survival in emergency department PE cases. These findings suggest that PEACE may serve as a valuable tool for rapid risk stratification, aiding emergency physicians in early clinical decision-making. Specifically, high PEACE Scores were associated with a greater need for thrombolytic therapy and ICU admission, suggesting its potential utility in guiding treatment escalation and resource allocation in critically ill PE patients. CLINICAL TRIAL NUMBER: Not applicable.
Kazım Ersin Altınsoy (Sat,) conducted a observational in Acute pulmonary embolism (n=120). PEACE Score was evaluated on Prediction of echocardiographic abnormalities (AUC 0.82, 95% CI 0.74-0.90, p=<0.001). The PEACE Score demonstrated high diagnostic value for predicting echocardiographic abnormalities in emergency department patients with pulmonary embolism, achieving an AUC of 0.82.
