Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The E-LUS study is a prospective, non randomised, monocenter case-control study.

The main objective is to evaluate the association of exercise lung ultrasound data acquired during a stress test on a bicycle ergometer with the diagnosis of heart failure with preserved ejection fraction (HFpEF).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Secondary objectives:

1. To assess the diagnostic performance of exercise lung ultrasound for the diagnosis of HFpEF.
2. To identify the value of the B-lines score on exercise maximizing the sensitivity and specificity for the diagnosis of HFpEF.
3. To evaluate the relationship of the delta of B-lines scores between rest and exercise with the diagnosis of HFpEF.
4. To assess the diagnostic performance of the delta of B-lines between rest and exercise for the diagnosis of HFpEF.
5. To identify the score of the delta of B-lines value between rest and exercise maximizing sensitivity and specificity for the diagnosis of HFpEF.
6. To evaluate the relationship between the resting value of the B-lines scores with the diagnosis of HFpEF.
7. To assess the diagnostic performance of the resting lung ultrasound for the diagnosis of HFpEF.
8. To identify the value of the B-lines score at rest maximizing the sensitivity and specificity for the diagnosis of HFpEF.
9. To evaluate the correlation between the B-line score measured at rest and exercise and the dyspnoea score measured at rest, during exercise, and during the recovery phase.
10. To assess the correlation of the delta of B-lines scores between rest and exercise and the dyspnoea score measured at rest, during exercise and during the recovery phase.
