What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if tracking blood sugar over three months with hemoglobin A1c accurately reflects levels in people with Left Ventricular Assist Devices (LVADs). Researchers will compare this method with continuous glucose monitoring (CGM) to assess whether CGM provides better blood sugar control and helps prevent low blood sugar episodes. The trial seeks participants with type 2 diabetes who have had an LVAD implanted after 2010 and can use a smartphone app to track their blood sugar data. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance diabetes management for LVAD patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. It mentions that any antihyperglycemic regimen (medications to lower blood sugar) is allowed, so you may be able to continue your current diabetes medications.

What prior data suggests that this method is safe for patients with LVADs?

Research has shown that managing diabetes in patients with Left Ventricular Assist Devices (LVADs) presents challenges. Patients with diabetes and LVADs face a higher risk of stroke compared to those without diabetes. This combination may also hinder heart recovery and increase the likelihood of complications.

However, SGLT2 inhibitors, a type of diabetes medication, have shown positive results in these patients. These medications have been associated with fewer deaths and hospital visits, as well as reduced heart failure issues and strokes.

Overall, despite the challenges, certain treatments can enhance the safety of LVADs for patients with diabetes.12345

Why are researchers excited about this trial?

Researchers are excited about using the Freestyle Libre 3 continuous glucose monitor (CGM) for patients with Type 2 Diabetes Mellitus (T2DM) who also have a Left Ventricular Assist Device (LVAD). Unlike traditional methods that require regular finger-prick blood tests, this CGM offers a more convenient and pain-free way to continuously track glucose levels in real-time. This can lead to better glycemic control without the hassle of constant manual monitoring. The potential for improved quality of life and more precise management of diabetes in these patients is what makes this approach particularly promising.

What evidence suggests that using a CGM is effective for managing blood sugars in patients with LVADs?

This trial will focus on subjects diagnosed with Type 2 Diabetes Mellitus (T2DM) who have a Left Ventricular Assist Device (LVAD). Participants will receive a Freestyle Libre 3 continuous glucose monitor (CGM) to help manage blood sugar levels. Research has shown that using a CGM can aid in controlling blood sugar, which is crucial as diabetes can worsen outcomes for people with LVADs. Studies have found that diabetic patients face a higher risk of complications and slower recovery after receiving an LVAD. However, effective blood sugar management can improve heart function and overall health. By comparing hemoglobin A1c, which measures long-term blood sugar, with real-time CGM data, researchers aim to find the best way to manage diabetes in these patients.16789
