Cardiac resynchronisation therapy in patients with chronic heart failure

Area of Science:

• Cardiology
• Medical Devices
• Heart Failure Management

Background:

• Ventricular dyssynchrony is a key factor in heart failure (HF) progression.
• Cardiac resynchronisation therapy (CRT) addresses HF by improving synchrony.
• Decades of research have refined CRT devices, techniques, and patient selection.

Purpose of the Study:

• To review the evolution and current guidelines for CRT in mild-to-severe HF.
• To explore emerging evidence for CRT in patient groups beyond current recommendations.
• To discuss challenges and solutions in CRT, including non-responders and optimization.

Main Methods:

• Review of extensive clinical experience and published literature.
• Analysis of guideline evolution based on clinical data.
• Discussion of technological advancements in CRT devices and implantation.

Main Results:

• CRT is a well-established therapy for selected HF patients.
• Evidence supports expanding CRT use to certain patient subgroups.
• Optimizing CRT and managing non-response are critical for success.

Conclusions:

• CRT has significantly advanced HF management.
• Personalized approaches and ongoing evaluation enhance CRT outcomes.
• Future directions include refining patient selection and remote monitoring.
