This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of pioglitazone compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
Pioglitazone is an oral drug for the treatment of type 2 diabetes that improves the utilization of glucose by the body by inhibiting hepatic gluconeogenesis, and has anti-inflammatory and antioxidant effects that may improve vascular endothelial cell injury and prevent cardiovascular disease. This study is to slow the process of aortic valve calcification by pioglitazone intervention with the aim of reducing the risk of aortic valve stenosis. Participants were randomized into two groups: one group was given oral pioglitazone treatment and the other group was given placebo control. Patients in both groups were observed for aortic valve calcification during the follow-up period, and changes in aortic valve thickness, degree of calcification, and flow were recorded by cardiac ultrasonography, while the incidence of cardiovascular events and adverse effects were assessed.

This study's planned enrollment of 100 is close to the median of 100 across 23 interventional studies indexed under Aortic Valve, Calcification of.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
