BACKGROUND: Left heart failure (LHF) is commonly associated with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) but its role is often underestimated. AIM OF STUDY: To evaluate the performance of a new diagnostic technique based on the measurement of the pulse amplitude ratio (PAR) using non-invasive ventilation (NIV) for the early identification LHF in patients admitted to the emergency department (ED) for AECOPD. RESULTS: 73 patients were included in this study: 32 in LHF group and 41 in non LHF- group. The two groups had comparable demographic and clinical characteristics at admission. The mean values of PARNIV was significantly higher among LHF patients (0.86 vs. 0.71; p < 0.01). The area under the receiver operating characteristic curve of PARNIV was 0.75. Using the best cut-off (0.6), the sensitivity of PARNIV was 93% with a specificity 21%, a positive predictive value of 48%, and a negative predictive value of 81%. Correlation between PARNIV and BNP was significant (r = 0.52; p = 0.002). CONCLUSION: Measurement of PARNIV in patients presenting to the ED with AECOPD had a good diagnostic performance for the detection of LHF and could represent an interesting alternative for the currently available methods. Trial registration The study was registered in the Clinical Trial Registration System (clinicaltrials.gov) under the study number NCT05189119, https://register.
