About this study

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

Patients presenting with idiopathic dilated cardiomyopathy and left ventricle dysfunction (LVEF <40%), naive of anti-remodeling cardiac medical therapy, will undergo invasive coronary microvascular assessment based on thermodilution. The primary endpoint, namely the left ventricle reverse remodeling, will be assessed after 12 months of optimal medical therapy based on transthoracic echocardiography. The primary endpoint will be evaluated by an independent central core lab. Patients enrolled in the study will be followed for a period of 5 years to monitor their clinical status. During the study period participants may undergo multimodality diagnostic tests including ECG telemetry monitoring, cardiopulmonary exercise testing, cardiovascular cardiac magnetic resonance.

Read the detailed description

This is a prospective, multicentric, single-arm explorative clinical study in patients presenting with heart failure and idiopathic dilated cardiomyopathy with LVEF ≤ 40%. Patients identified as eligible for the protocol will be asked for written informed consent to participate in the study.

After appropriate treatment of the acute heart failure phase, participants will undergo coronary angiography to rule out obstructive coronary disease.

Fractional flow reserve (FFR) will be assessed as per standard clinical practice and a value ≤ 0.80 will be considered abnormal. Microvascular assessment will be performed using the same pressure/thermodilution guidewire used for FFR assessment with the derivation of coronary flow reserve (CFR), index of microcirculatory resistance (IMR) and the microvascular resistance reserve (MRR).

Steady-state hyperemia will be obtained using an intravenous adenosine infusion or intracoronary papaverine as per routine clinical practice.

The primary endpoint will be assessed based on the variation of echocardiographic indices from the baseline to 12-month follow up. Transthoracic echocardiography will be performed to confirm the diagnosis and obtain information about adverse cardiac remodeling and after 12 months of optimal medical therapy to evaluate reverse remodeling.

Patients will be clinically managed by a dedicated heart failure team to optimize medical therapy and organize the follow-up.

Patients enrolled in the study will be clinically followed for a period of 5 years to monitor the clinical status and report major adverse cardiac events.

During the study period participants may undergo multimodality diagnostic tests according to the recent international guidelines. Data from these tests will be collected if the test will be performed per clinical practice:

  1. 3-leads ECG telemetry monitoring (or 24 hours Holter ECG) to detect or quantify atrial and/or ventricular arrhythmias during the hospitalization.
  2. N-terminal pro-B-type natriuretic peptide (NT - proBNP).
  3. Cardiopulmonary exercise testing (CPET) to assess functional capacity.
  4. Contrast enhanced cardiac magnetic resonance. CMR assessment may be repeated at 12 months follow-up.
  5. Genetic counseling and genetic testing, performed by an appropriately trained healthcare professional is recommended in patients with idiopathic DCM by the latest international guidelines to enable diagnosis, prognostication, therapeutic stratification.

  3. Changes in functional capacity at cardiopulmonary exercise test

    Variations of VO2 max at CPET after 12 months of guidelines-defined OMT

    Measured: After 12 months of guidelines-defined OMT

  4. Prevalence of different CMD endotypes and their correlation with the severity of adverse cardiac remodeling.

    CMD endotypes (defined as IMR >25 units and/or CFR <2)

Model description
Prospective multicenter single-arm experimental study. The study aims to perform a functional study of the coronary microcirculation with pressure guides, in patients with new diagnoses of dilated cardiomyopathy and clinical indication for coronary angiography. Following this, a multiparametric imaging study with transthoracic echo cardiography will be performed. 12 months after the optimization of medical therapy, the patient will receive a clinical, laboratory and instrumental re-evaluation of transthoracic cardiac color Doppler. The primary endpoint is the recovery of left ventricular function on cardiac imaging. Follow up will continue up to 5 years from enrollment through telephone contacts, outpatient visits and review of clinical data.
