Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
This is a single centre, investigator-led study of the regional origins of biomarkers in patients with heart failure (heart failure with reduced ejection fraction: HFrEF, and heart failure with preserved ejection fraction: HFpEF) , and of the relationship between biomarkers in cardiovascular function.
It consists of two parts of visit: initial visit will assess participants' eligibility via face-to face consultation. If they are qualified, patients will proceed for second visit which is the procedure called right heart catheterization.
The right heart catheterisation will take around one hour on your second visit. It involves insertion of a catheter (a thin plastic tube) into a large vein usually in the arm but sometimes in the right side of the neck (jugular vein) using ultrasound to identify the correct placement. Through this tube a smaller tube will be advanced step by step to the heart, lungs, kidney and liver using x-ray guidance to measure the blood pressure and to collect a blood sample from each location. A fine tube will also be placed into an artery located at the wrist or elbow under local anaesthetic to measure your blood pressure and to collect blood samples.
There is a visit checklist detailing the component of each visit including vital signs, blood samples, medical history etc. and further details are explained in the PICF.
Patients having heart failure with reduced ejection fraction and patients with preserved ejection fraction will undergo the same procedures.

Summary
Brief summary
This is a single centre, investigator-led study of the regional origins of biomarkers in patients with heart failure (heart failure with reduced ejection fraction: HFrEF, and heart failure with preserved ejection fraction: HFpEF) and in healthy control subjects, and of the relationship between biomarkers in cardiovascular function.
The past studies have demonstrated the association between many biomarkers in the peripheral blood only and the regional blood is somewhat lack of information. This study is hypothesized to investigate the biomarkers at regional blood sampling to better understand the pathophysiology of heart failure
