Non-classical indications for cardiac resynchronization therapy.
Based on randomized controlled studies, cardiac resynchronization therapy (CRT) is currently indicated in patients with systolic heart failure of New York Heart Association (NYHA) functional class III and IV, left ventricular ejection fraction <35% and wide QRS (>120 ms). Most of the enrolled patients were in sinus rhythm, were not previously paced and had mainly LBBB. Thus, there are uncertain...
متن کاملCardiac resynchronization therapy. Indications and contraindications.
Progress in medical therapy wouldn't be possible without the contribution of the scientific community. Several randomized controlled trials have led to our current guidelines. Specifically, COMPANION and CARE-HF trials involved a turning point for cardiac resynchronization therapy, which became well recognized for the treatment of heart failure patients with QRS≥120ms, ejection fraction≤35%, an...
متن کاملSelection for Cardiac Resynchronization Therapy
SEE PAGE 969 C ardiac resynchronization therapy (CRT) is a highly effective treatment for some patients with heart failure. Current guidelines recommend the implantation of CRT devices in patients with left ventricular (LV) dysfunction and electrical dyssynchrony, evidenced by a left bundle branch block (1). Unfortunately, not all patients suitable for CRT derive symptomatic benefit—an unsatisf...
متن کاملCardiac-resynchronization therapy.
Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...
متن کاملCardiac Resynchronization Therapy
According to the 2013 update on heart disease statistics from American Heart Association, an estimated 5.1 million Americans ≥20 years of age have a diagnosis of heart failure. In the year 2009, heart failure was noted to be the primary cause of death in >56 000 people and contributed to death of >274 000 people. It is one of the most common causes of hospitalization in patients ≥65 years of ag...
