No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.

Summary

The objective of the study was to estimate the efficacy of telmisartan and amlodipine combination on the restoration of left atrial mechanical function after atrial fibrillation catheter ablation.
