Assessing microvascular dysfunction to improve heart failure treatment

Microvascular Dysfunction Assessment to Predict Left Ventricular Reverse Remodeling in Idiopathic Dilated Cardiomyopathy

NA · Azienda Ospedaliera Universitaria Integrata Verona · NCT06356727

What this trial studies

This clinical trial focuses on patients with idiopathic dilated cardiomyopathy and left ventricular dysfunction who have not yet received anti-remodeling cardiac therapy. Participants will undergo invasive assessments of coronary microvascular function using thermodilution techniques, followed by optimal medical therapy for 12 months. The primary goal is to evaluate left ventricular reverse remodeling through echocardiography after treatment. The study will also monitor patients' clinical status over a five-year period, utilizing various diagnostic tests to gather comprehensive data.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with a first diagnosis of idiopathic dilated cardiomyopathy and left ventricular ejection fraction of 40% or less.

Not a fit: Patients with obstructive coronary artery disease or a history of significant cardiac events such as myocardial infarction or valvular heart disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment strategies for heart failure patients, enhancing their heart function and overall health.

How similar studies have performed: While this approach is innovative, similar studies assessing microvascular function in heart failure have shown promising results, indicating potential for success.
