CRTd Responders Optimization

Suboptimal optimization of atrio-ventricular (AV) and inter-ventricular (VV) timings could affect the clinical response of CRTd in T2DM patients. Thus, authors hypothesize that automatic sensor guided CRTd optimization could ameliorate clinical outcomes in patients with T2DM. However, authors will evaluate the effects of cardiac resynchronization therapy (CRTd) in patients with type 2 diabetes mellitus (T2DM) optimized via automatic vs. echocardiographic guided approach.Authors will conduct a prospective, multicenter study to recruit, from October 2016 to June 2019, patients with T2DM and heart failure (HF) candidate to receive a CRTd. After CRTd the patients will be optimized via automatic vs. echocardiographic guided approach.
