Abstract

The natural history of premature ventricular complex (PVC)-induced cardiomyopathy is incompletely understood. The purpose of this study was to assess long term follow-up data in patients who underwent successful PVC ablation for PVC-induced cardiomyopathy. The subjects of this study were 60 patients (17 women; mean age 52.5 ± 16.8 years; ejection fraction [EF] 37.3 ± 8.5%, median 40%, interquartile range [IQR] 15) with PVC-induced cardiomyopathy who underwent successful ablation of their predominant PVCs between 2005 and 2012. Patients were followed up for a mean of 23.6 ± 17.2 months. EF improved to 57.2 ± 4.7% (median 55%, IQR 5; P = .0001) within 9.6 ± 8.4 months of the ablation procedure. During follow-up, 10 of 60 patients (16.7%) had recurrent frequent PVCs and 50 patients (83.3%) did not. Patients underwent repeat assessment of EF and PVC burden. During follow-up of 23.6 ± 17.2 months, 10 patients had recurrent frequent PVCs, with an increase of their PVC burden from 1.4 ± 0.9% (median 1.05%, IQR 1.59) after the initial ablation to 27.2 ± 8.8% (median 26.0%, IQR 18.2; P = .018). Their EF decreased from 55.7 ± 3.4% (median 55%, IQR 5.8) after the initial ablation to 40.2 ± 5.1% (median 40%, IQR 15; P = .005). In the remai...Continue Reading

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
