About

The investigation of biomarkers for immune status and metabolic state, as well as host microbiota composition, in patients with ventricular arrhythmias before and after radiofrequency ablation, can provide new insights for specific and personalized treatment. This can help establish early prediction and prognosis models and provide a basis for clinically effective diagnosis and treatment.

Full description

Abnormal immune and metabolic states can lead to the occurrence of various systemic diseases, including the development of cardiovascular diseases through multiple mechanisms. On the other hand, various diseases can also feedback and regulate the immune and metabolic systems. However, currently there is no research on the impact of immune and metabolic states on ventricular arrhythmia. Exploring the biomarker characteristics and risk stratification of patients with ventricular arrhythmias undergoing radiofrequency ablation before and after the procedure can provide new insights for specific and personalized treatment. It can establish early prediction and prognostic models, providing evidence for clinically effective diagnosis and treatment.

Trial design

5,000 participants in 5 patient groups

Occasional premature ventricular contractions group

Description:

Premature ventricular contractions (PVCs) occur when an electrical impulse originates from an ectopic focus within the ventricle or the interventricular septum, causing premature depolarization of the ventricle before the impulse from the sinoatrial node has reached the ventricle. Occasional PVCs refer to PVCs that occur less than 6 times per minute.

Treatment:

Other: Observational; No Interventions were given.

Frequent premature ventricular contractions group

Description:

Premature ventricular contractions (PVCs) occur when an electrical impulse originates from an ectopic focus within the ventricle or the interventricular septum, causing premature depolarization of the ventricle before the impulse from the sinoatrial node has reached the ventricle. Frequent PVCs refer to PVCs that occur more than 6 times per minute.

Treatment:

Other: Observational; No Interventions were given.

Short runs of ventricular tachycardia group

Description:

Premature ventricular contractions (PVCs) occur when an electrical impulse originates from an ectopic focus within the ventricle or the interventricular septum, causing premature depolarization of the ventricle before the impulse from the sinoatrial node has reached the ventricle. Short runs of ventricular tachycardia refer to three or more consecutive PVCs that occur within 30 seconds.

Treatment:

Other: Observational; No Interventions were given.

Sustained ventricular tachycardia group

Description:

Sustained ventricular tachycardia (VT) is defined as ventricular arrhythmia that lasts for at least 30 seconds and has a heart rate exceeding 100 bpm, or requires termination before 30 seconds due to hemodynamic instability.

Treatment:

Other: Observational; No Interventions were given.

Ventricular fibrillation group

Description:

Ventricular fibrillation refers to the complete disappearance of QRS waves, ST segments, and T waves in the ECG, replaced by different shapes, varying amplitudes, and extremely irregular ventricular fibrillation waves.

Treatment:

Other: Observational; No Interventions were given.
