The Role of Cardiac Mechanics, Circulating Biomarkers and Frailty in Aortic Stenosis in Predicting Outcomes After Aortic Valve Intervention.
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.
• Part I - Patients part of the TOPCAT cohort from Americas fulfilling inclusion criteria of Part II-Group 3 (see below) and/or patients enrolled in the Part II study
• 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
