Assessing the prognostic significance of mean pulmonary artery velocity in heart failure with slightly reduced ejection fraction
Copyright © 2023. Published by Elsevier Inc..
OBJECTIVE: In this study, we assessed the prognostic significance of the mean velocity of the pulmonary artery (mvPA) using CMR in patients who have heart failure with mildly reduced ejection fraction (HFmrEF) and pulmonary hypertension, both as a combined condition and individually.
METHODS: This retrospective study involved 284 consecutive patients diagnosed with HFmrEF who were hospitalized and underwent CMR imaging to assess RV-PA coupling parameters, including mvPA. We collected baseline data clinical profiles, lab test results, and cardiac imaging findings of patients with HFmrEF who had at least two echocardiograms conducted three months apart. The primary endpoint was a composite of all-cause mortality or readmission due to heart failure.
RESULTS: A total of 139 patients met the primary endpoint during an average follow-up of 49 months. The most effective threshold value for predicting the primary endpoint, determined by a receiver operating curve analysis, was 9. cm/s for mvPA. According to the Kaplan-Meier survival plots, when mvPA ≤ 9.05 cm/s, there was a significantly higher mortality rate (Log-Rank: 71.93, p < 0.001). It is important to highlight that the predictive value of mvPA remained consistent, irrespective of RV function. mvPA ≤ 9.05 cm/s served as an independent prognostic indicator, alongside ischemic cardiomyopathy and hyponatremia.
CONCLUSIONS: mvPA has affirmed its significance as an initial prognostic indicator by identifying a group of high-risk patients who have sustained RV function. While the results of this study displayed potential in stratifying the extended prognosis of patients with HFmrEF, additional research is required.
