Summary
The Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) report covers 5 years of data from over 4,000 patients. Continuous-flow pumps show over 80% survival at 1 year and 70% at 2 years.
Area of Science:
- Cardiology
- Medical Device Technology
- Clinical Data Analysis
Background:
- The Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) database tracks patients receiving mechanical circulatory support.
- The registry has collected data for over 4,000 patients since its inception.
Purpose of the Study:
- To summarize and analyze the first five years of patient and data collection within the INTERMACS registry.
- To examine the evolution of pump technology, implant strategies, and pre-implant patient profiles.
- To perform a risk factor analysis on the adult primary implant population.
Main Methods:
- Analysis of a large patient database (over 4,000 patients) from the INTERMACS registry.
- Review of pump technology advancements and implantation strategies.
- Examination of pre-implant patient characteristics and risk factors.
Main Results:
- The report chronicles the evolution of pump technology and implant strategies over five years.
- A comprehensive risk factor analysis of the adult primary implant population is presented.
- Current actuarial survival rates with continuous-flow pumps exceed 80% at 1 year and 70% at 2 years.
Conclusions:
- The INTERMACS registry provides valuable insights into the use of mechanical circulatory support.
- Continuous-flow pumps demonstrate significant long-term survival benefits.
- Ongoing data collection and analysis are crucial for advancing patient care in mechanical circulatory support.
