Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We examined the feasibility and reliability of a combined echocardiographic and right heart catheterization (RHC) approach for right ventriculo/arterial (R-V/A) coupling assessment in HF patients with dilated cardiomyopathy (D-CMP).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single center, retrospective cross-sectional study. In 2016-17, for 6 months, we evaluated for eligibility 81 consecutive D-CMP patients afferent to "Niguarda Great Metropolitan Hospital" for RHC and echocardiography. All participants underwent the exams in the context of heart-transplant or advanced HF evaluation. Inclusion criteria were: 18 years old, given informed consent, D-CMP, New York Heart Association (NYHA) functional class II or III and reduced EF (≤ 35%). On the contrary, exclusion criteria were: missing the inclusion criteria and refused informed consent. The final sample consisted of 68 study participants (mean age 64±7 years, 82 % male).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No Pulonary Hypertension

the presence of mean pulmonary pressures (PAPm) at the right heart catheterization \< 25 mmHg

Ventriculo-arterial coupling assessment (R-V/A)

Intervention Type DIAGNOSTIC_TEST

R-V/A was achieved by computing the R-Elv/P-Ea ratio (Right ventricular elastance/Pulmonary arterial elastance). R-Elv was computed as PAPm / end-systolic area (ESA) of the right ventricle. P-Ea was obtained as (PAPm-PCWP)/ right ventricle stroke volume (R-SV).

Postcapillary Pulmonary Hypertension

PAPm ≥ 25 mmHg and postcapillary wedge pressure (PCWP) \>15 mmHg

Ventriculo-arterial coupling assessment (R-V/A)

Intervention Type DIAGNOSTIC_TEST

R-V/A was achieved by computing the R-Elv/P-Ea ratio (Right ventricular elastance/Pulmonary arterial elastance). R-Elv was computed as PAPm / end-systolic area (ESA) of the right ventricle. P-Ea was obtained as (PAPm-PCWP)/ right ventricle stroke volume (R-SV).

combined postcapillary/precapillary Pulmonary Hypertension

PAPm ≥ 25 mmHg, PAWP \>15 mmHg and diastolic peak gradient (DPG - diastolic pulmonary pressure - PCWP) ≥7 mmHg and/or pulmonary vascular resistence (PVR) \>3 WU, where available.

Ventriculo-arterial coupling assessment (R-V/A)

Intervention Type DIAGNOSTIC_TEST

R-V/A was achieved by computing the R-Elv/P-Ea ratio (Right ventricular elastance/Pulmonary arterial elastance). R-Elv was computed as PAPm / end-systolic area (ESA) of the right ventricle. P-Ea was obtained as (PAPm-PCWP)/ right ventricle stroke volume (R-SV).
