Insulin Treatment in Diabetic Older People With Heart Failure.

Summary

Cardiac failure (HF) and type 2 diabetes mellitus (T2DM) are two clinical conditions with a significant impact on public health worldwide. In the elderly population the prevalence of T2DM is constantly increasing as well as its incidence in all Western countries including Italy. The combination of HF and T2DM is frequent and leads to an increased risk of death and of non-fatal adverse cardiovascular (CV) events which justifies the frailty of this population. Although diabetic patients (pts) with HF respond to recommended treatments for HF, the effective and safe control of blood glucose levels is still an outstanding clinical problem, since glucose lowering drugs may increase the risk of CV adverse events. Insulin, used in about 30% of diabetic patients with HF, causes adverse effects such as fluid and sodium retention and unwanted effects of hypoglycemia. Even if insulin remains a milestone in glucose lowering therapy of T2DM, its risk/benefit ratio is still controversial, more so when given to old patients with HF. The issue has gained relevance since new antidiabetic agents, as the sodium glucose co-transporter 2 (SGLT- 2) inhibitors and glucagon-like peptide (GLP-1) analogues, with a safer CV profile have been made available. While the transferability of the CV benefits attributed to the new drugs needs to be assessed in clinical practice, the present study explore the benefit/risk profile of insulin in HF. Objectives: to assess comparatively in patients with heart failure and T2DM the benefit/risk profile over 1-year follow-up of two antidiabetic strategies, standard care with vs without insulin in terms of humoral and clinical endpoints including body weight change, all-cause mortality and burden of care components (hospitalizations for CV events and episodes of severe hypoglycemia).
