Insights
Progressive heart failure involves worsening cardiac function and increased heart size. A Cardiac Support Device may mitigate this progression by reducing ventricular wall stress.
Area of Science:
- Cardiology
- Biomedical Engineering
Background:
- Progressive heart failure leads to cardiac dysfunction and increased heart size.
- Elevated ventricular wall stress exacerbates heart failure progression.
- Myocardial stretch is a key factor in heart failure development.
Purpose of the Study:
- To investigate the potential of a Cardiac Support Device to mitigate heart failure progression.
- To evaluate the device's ability to reduce ventricular wall stress and myocardial stretch.
Main Methods:
- Preclinical evaluations of the Cardiac Support Device.
- Clinical assessments of device efficacy in heart failure patients.
Main Results:
- Preclinical data support the device's effectiveness.
- Clinical evaluations indicate positive outcomes in mitigating heart failure progression.
Conclusions:
- Passive support with a Cardiac Support Device shows promise in managing heart failure.
- Reducing ventricular wall stress is a viable strategy for heart failure treatment.
Abstract:
Progressive heart failure is characterized by loss of cardiac function associated with maladaptive changes in myocardial gene expression and neuroendocrine activity, leading to progressive increases in heart size. Elevated ventricular wall stress results from an increase in chamber size, and is thought to play a role in furthering development towards end-stage disease. Reduction of wall stress and stress mediated myocardial stretch may be an important means for mitigating heart failure progression. One possible approach to accomplish this goal is through passive support of the heart with the Cardiac Support Device. Results from preclinical and clinical evaluation give support to this premise.
