Обзор
To evaluate mirabegron's effect on ventricular arrhythmia control. The study will be conducted in ambulatory patients with ventricular tachycardia (VT), organic heart diseases, and an implantable cardioverter-defibrillator (ICD). The investigators will perform a pilot study involving 20 patients. Each will receive 50 mg of mirabegron. All will have neuECG recordings made before and 2 months after mirabegron. The data will be analyzed to test the proposed hypothesis.
Подробное описание
Objectives:
Primary objective: To evaluate if mirabegron can reduce the VT burden. Secondary objective: To test the hypothesis that mirabegron can reduce the average skin sympathetic nerve activity (aSKNA).
Endpoints: The primary endpoint is the burden of VT detected by ICD. The secondary endpoint is the average skin sympathetic nerve activity, symptoms, and quality of life (QOL) questionnaires.
Study Population: This is a pilot study in patients with an ICD and, on average, \> 2 episodes of VT per month over the past 2 months despite guideline-recommended medical therapy (GRMT).
Phase: Phase 2.
Description of Sites/Facilities Enrolling Participants: The investigators will enroll patients in the cardiac device clinic at the Smidt Heart Institute, Cedars-Sinai Medical Center. Dr. Ashkan Ehdaie (co-investigator) directs the clinic, which routinely follows up on patients with ICDs.
Description of Study Intervention: The investigators will give the patients 50 mg/day of mirabegron orally for three months.
Study Duration: One-year.
Participant Duration: Approximately three months. The primary endpoint takes 2 months to complete. The investigators will call the patient at 3 months to determine if there are any complications. The patient will then exit the study.
Вмешательства
- Препарат Mirabegron
Mirabegron is a beta-3 agonist approved by FDA to treat overactive bladder. Our preclinical studies showed that it is antiarrhythmic in the ventricles.
Первичные конечные точки
- The primary endpoint is reduction of the burden of VT detected by ICD [Срок оценки: 3 months]
Критерии участия
Критерии включения
- In order to be eligible to participate in this study, an individual must meet all the following criteria:
- Provision of signed and dated informed consent form.
- Age > 18 years old.
- Documented VT on ICD.
- with > 2 episodes of VT per month (on average) over the past 2 months.
- despite guideline-recommended medical therapy (GRMT).
Критерии исключения
- An individual who meets any of the following criteria will be excluded from participation in this study:
- Patients who are pacemaker-dependent because the pacing artifacts will complicate skin sympathetic nerve activity (SKNA) analysis.
