Heart & Diabetes - Feasibility Study

23 mars 2016 mis à jour par: Medtronic Bakken Research Center
The main purpose of this study is to validate an intensive protocol of insulin infusion and subsequent subcutaneous insulin administration with the support of continuous glucose monitoring, in addition to reference finger-stick values.

Description détaillée

Heart failure is a common disease (prevalence worldwide: 22 million; incidence worldwide: 2 million; prevalence in Italy: 750.000; incidence in Italy: 170.000), affecting 1-2% of overall population and accounting for a significant proportion of healthcare costs. Recurrent hospital admissions represent the majority of the disease-related cost. About 15-25% of patients with HF are diabetics: the presence of diabetes significantly worsens prognosis in patients with heart failure and increases the risk of death by 30% compared to subject without diabetes.

The intensive control of glycemia during acute heart failure is an objective of primary importance, which can be obtained only with a proper strategy of patient management and with a considerable organizational effort. In a shared protocol aimed at a tight control of glycemia, the use of Continuous Glucose Monitoring (CGM) is expected to allow an easier management of the patient and a more accurate implementation of the protocol.

The main purpose of this study is to validate an intensive protocol of insulin infusion and subsequent subcutaneous insulin administration with the support of continuous glucose monitoring, in addition to reference finger-stick values.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Treatment
All patients will be submitted to a shared intensive protocol of insulin infusion supported by continuous glucose monitoring

The intensive control of glycemia is obtained with a shared in-hospital insulin infusion protocol, supported by the use of a continuous glucose monitoring system (Medtronic Guardian REAL Time). Any sudden variation of glycemia levels and/or alarms, as indicated by the device, has to be confirmed with a finger-stick before any therapy modification.

In-hospital management is subdivided in a 2-day intensive and a 3-day post-intensive phase.
