Abstract

Ventricular arrhythmic events have a strong impact on the mortality of patients with heart failure. The benefits of the optimized drug treatment of heart failure in reducing ventricular arrhythmia have not been well documented yet. To analyze the effects of the optimized drug treatment of heart failure on ventricular arrhythmia. This is a clinical study with a non-randomized design of 85 consecutive (open cohort) non-selected patients, with a mean age of 63.8+/-12.2 years; 42 were males and 43 were females. All patients had a diagnosis of heart failure (HF), NYHA Functional Class II to IV, EF <or=0.40 and, after treatment optimization, they were followed from January 2002 to May 2004, regarding the ventricular arrhythmia behavior, at admission and at the end of the study. At the start of the study, 60% of patients presented more than 1,000 ventricular extrasystoles in 24 hours, 100% pairs and 100% nonsustained ventricular tachycardia (NSVT). During a follow-up period of 8 to 27 months (20.0 + 4.8 months) a significant decrease in the total number of ventricular extrasystoles/24 hrs, number of pairs and number of NSVT episodes was observed (p<0.05). The improvement in functional class and performance at the six-minute walk test ...Continue Reading

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.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
