Summary
The role of cardiac mechanics, circulating biomarkers and frailty in predicting outcomes in patients with aortic stenosis after aortic valve replacement (SCRABLES -The 2-Parts Study) Part I: Observational study to characterize phenotypes, structural alterations and biomarkers profiles in a broad spectrum of patients with aortic stenosis and heart failure with preserved ejection fraction (HFpEF). Part II: Prospective cohort study to characterize patients' phenotypes, cardiac structural alterations, circulating biomarkers and frailty in order to optimize risk stratification and patient selection for aortic valve intervention.
Eligibility
Inclusion Criteria2
- Part II - Segment A and B Age ≥ 18 years old AS classified according to aortic valve area measured by Doppler echocardiography Group 1: Moderate AS (1.0-1.5cm2) Group 2: Severe AS (1cm2) Group 3: HF with preserved left ventricular ejection fraction (LVEF ≥45%) without significant AS
- Part II - Segment C (Control Group) Age ≥ 18 years old Healthy subject taking into account exclusions parameters at the time of screening Able to sign the consent form
