Abstract

BACKGROUND: Data are limited regarding whether the presence of diabetes mellitus (DM) influences the benefit of cardiac resynchronization with defibrillator therapy (CRT-D) in heart failure (HF) patients. METHODS AND RESULTS: The effect of CRT-D was evaluated in 1817 patients who were enrolled in the Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy (MADIT-CRT). Patients were minimally symptomatic (New York Heart Association class I or II), with ejection fraction ≤0.30 and QRS ≥130 ms. We used Cox regression to determine hazard ratio (HR) of CRT-D versus implantable cardioverter-defibrillator (ICD) therapy for the risk of HF event or death, whichever came first (MADIT-CRT primary end point), in DM (n=552) and non-DM (n=1265) patients. Compared with the non-DM patients, those with DM had more coronary risk factors. During an average follow-up of 2.4 years, DM patients had significantly more primary end point events than non-DM patients (26.6% versus 18%, P<0.001). CRT-D was associated with a significant reduction in risk of primary end point in both DM (HR=0.56, P<0.001) and non-DM patients (HR=0.67, P=0.003). Compared with non-DM patients, CRT-D:ICD HRs in DM patients were lower in the total population, and in subgroups with ischemic cardiomyopathy (0.63 versus 0.64), nonischemic cardiomyopathy (0.39 versus 0.73), and left bundle-branch block (0.36 versus 0.50). There were no significant differences in ventricular remodeling, arrhythmia events, or device-related complications between DM and non-DM patients. CONCLUSIONS: Patients with diabetes, left ventricular dysfunction, mildly symptomatic HF, and wide QRS complex derive similar benefit from CRT-D compared with patients without diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
