Interesting article I came across recently.Worth a read
Heart failure death risk is reduced with cardiac resynchronization therapy (CRT). Research has found that those with implanted CRT can have a longer lifespan than those who receive traditional implantable cardioverter defibrillator (ICD).
The first study looked at CRT-D (CRT with defibrillator) in mildly symptomatic patients. The researchers found that patients who had CRT-D implanted for a left bundle branch block had a 41 percent reduction in death risk, compared to those who had ICD. Probability of early mortality at seven years was 18 percent for CRT-D patients and 29 percent for ICD patients. Five-year survival rate for CRT-D patients was nearly 90 percent.
Lead investigator Dr. Ilan Goldenberg said, “Based on our findings, we now have an intervention that can potentially change the outcomes for certain heart failure patients. We can intervene early in the course of the disease to reduce the risk of long-term mortality in these patients.”
The Multicenter Automatic Defibrillator Implantation with Cardiac Resynchronization Therapy trial enrolled 1,820 patients with mild or no heart failure symptoms and patients randomly received CRT-D or ICD. Enrolled patients were diagnosed with New York Heart Association Class 1 or 2 (mild) heart failure, left ventricular dysfunction, and an ejection fraction of 30 percent or lower.
