Evaluating heart failure patients in Singapore receiving cardiac resynchronization therapy

Prospective Evaluation of Asians With CRT for Heart Failure

Observational National University Heart Centre, Singapore · NCT02814942

This study looks at heart failure patients in Singapore receiving a specific heart treatment to see how their health changes over a year and what factors might help predict their response to the treatment.

What this trial studies

This observational study aims to assess the baseline characteristics and long-term outcomes of heart failure patients in Singapore who are undergoing cardiac resynchronization therapy (CRT). It collects demographic data, ECG parameters, echocardiographic measurements, and blood biomarkers before and after the CRT procedure. The study will analyze these factors to identify predictors of response to CRT, defined by specific changes in left ventricular function over a 12-month period. The findings may help improve patient selection and treatment strategies for CRT in heart failure.

Who should consider this trial

Good fit: Ideal candidates for this study are adults with symptomatic heart failure, a broad QRS duration greater than 120 ms, and an ejection fraction of less than 40% who are not on optimal medical therapy.

Not a fit: Patients who are pregnant, under 18 years of age, have an active infection, or are unable to provide consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of which heart failure patients are most likely to benefit from CRT, leading to better treatment outcomes.

How similar studies have performed: Other studies have shown success in evaluating CRT outcomes in diverse populations, but this specific focus on Asian patients is relatively novel.
