Shall CRT-D be downgraded to CRT-P in super-responders of cardiac resynchronization therapy?

Cardiac Resynchronisation Therapy and Heart Failure: Persepctive from 5P Medicine

Chronic heart failure is still a major challenge for healthcare. Currently, cardiac resynchronisation therapy (CRT) has been incorporated into the updated guideline for patients with heart failure, left ventricular ejection fraction ≤35 % and prolonged QRS duration. With 20 years of development, the concept of 'from bench to bedside' has been illustrated in the field of CRT. Given the fact that the indications of CRT keep evolving, the role of CRT is not limited to the curative method for heart failure. We therefore summarise with the perspective of 5P medicine - preventive, personalised, predictive, participatory, promotive, to review the benefit of CRT in the prevention of heart failure in those with conventional pacemaker indications, the individualised assessment of patient's selection, the predictor of responders of CRT, and the obstacles hindering the more application of CRT and the future development of this device therapy.
