Thoracic Epidural Anesthesia Reduces Mortality and Rehospitalization for Patients With Heart Failure With Reduced Ejection Fraction

March 12, 2024 updated by: First Affiliated Hospital of Harbin Medical University

Thoracic Epidural Anesthesia Reduces Mortality and Rehospitalization for Patients With Heart Failure With Reduced Ejection Fraction：a Retrospective Matched Case-control Study

Despite significant scientific breakthrough in management, patients with heart failure with reduced ejection fraction (HFrEF) remain high morbidity and mortality, with a 5-year survival rate of 25% after hospitalization for HFrEF. The autonomic nervous system (ANS), particularly the sympathetic nervous system (SNS), plays a critical compensatory role in maintaining cardiovascular homeostasis in the failing heart. This is critical given the huge unmet need for novel treatment strategies for HFrEF.

Thoracic epidural anesthesia (TEA), the infusion of anesthetic agents (eg, lidocaine or ropivacaine) into the epidural space, is used to achieve sympathetic block at the T1 to T4 levels in thoracic and abdominal surgical procedures. Since 1995, Professor Liu Fengqi has pioneered the use of TEA to treat end-stage HFrEF and achieved surprising results. TEA could reduce the enlarged heart cavity, halt and reverse cardiac remodeling, and improve cardiac systolic and diastolic function. Currently, thousands of HFrEF patients have received TEA procedure. However, it is unclear whether TEA could positively impact the clinical outcomes of patients with HFrEF.

Study Overview

Status

Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • The present study was a retrospective, observational, matched case-control study of 1,840 consecutive inpatients, in New York Heart Association functional class II-IV with a left ventricular ejection fraction (LVEF) ≤40%, who were hospitalized from July 2013 to August 2019.

Exclusion Criteria:

  • Patients were excluded because of insufficient patient information, refusal to participate, or loss to follow-up by telephone. In patients with multiple hospitalizations during the time period, the first hospitalization was utilized in the analysis.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of heart failure mortality in the patients with HFrEF
Time Frame: 8.5 years
Rate of heart failure mortality in the patients with HFrEF
8.5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
