AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with moderate or severe aortic stenosis, or heart failure with preserved ejection fraction without significant aortic stenosis. It also takes healthy adults as a control group.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- Group 1: moderate aortic stenosis (valve area 1.0-1.5cm2). Group 2: severe aortic stenosis (valve area 1cm2). Group 3: heart failure with preserved left ventricular ejection fraction (LVEF ≥45%) without significant aortic stenosis. Control group: healthy people.
- Earlier treatment
- People who already had aortic valve replacement, by surgery or by valve implantation through a vessel, cannot join.
Main reasons for not taking part
- Prior aortic valve replacement
- Severe mitral valve disease or aortic regurgitation
- LVEF below 45%
- Heart attack within the previous 3 months
- Known active infection or cancer

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.
Inclusion: 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.
Exclusion: Part II - Segment C (Control Group) History of cardiovascular disease Risk factors associated with cardiovascular (treated diabetes, hypertension, body mass index >30kg/m2) Pregnancy or breastfeeding All other cause from Segment A and B; Part I and II - Segment A and B Prior AVR either by surgery or trans-aortic valve implantation; Severe mitral valve disease or aortic regurgitation; LVEF < 45% Myocardial infarction within the previous 3 months; Angina limiting the 6MWTD and thought to be the result of severe coronary artery disease; Cerebrovascular transient ischemic attack or stroke within the previous 6 months; Known active infection or cancer; renal insufficiency (glomerular filtration rate <30 mL/min/1.73m2) or end-stage renal disease; Significant anemia (haemoglobin <90 g/L) or thrombocytopenia (platelet count <50), history of bleeding diathesis or coagulopathy; Life expectancy <12 months due to non-cardiac co-morbid conditions; Chronic obstructive pulmonary disease with Global initiative for chronic obstructive lung disease (GOLD) stages 3-4; musculoskeletal disease limiting the ability to perform the 6MWTD.
