Inverse Relationship of Blood Pressure to Long-Term Outcomes and Benefit of Cardiac Resynchronization Therapy in Patients With Mild Heart Failure A Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy Long-Term Follow-Up Substudy

摘要

Background Previous studies have shown that low blood pressure is associated with increased mortality and heart failure (HF) in patients with left ventricular dysfunction. Cardiac resynchronization therapy (CRT) was shown to increase systolic blood pressure (SBP). Therefore, we hypothesized that treatment with CRT would provide incremental benefit in patients with lower SBP values.
