Alteration of Myocardial Deformations in Diabetes: Relationship to

Status Completed

Clinical Trial Summary

Despite careful monitoring of patients with diabetes, it is so far difficult to predict the occurrence of cardiac events in the evolution. As shown by various studies conducted in patients with diabetes, cardiac involvement can be detected by abnormalities of diastolic or systolic functions using non-invasive investigations such as echocardiography. For 4 years, the evaluation technique of myocardial deformations by two-dimensional speckle tracking strain by echocardiography is the subject of high hopes in the earlier detection of still asymptomatic cardiomyopathies. In the present study, the investigators hypothesized that this technique would improve the detection of myocardial contraction abnormalities in patients with insulin-dependent diabetes mellitus (IDDM), and would establish their association with micro-angiopathy, frequently encountered in these patients.

Clinical Trial Description

This is a single center case-control study based on routine care, designed to recruit patients with type 1 diabetes mellitus free from any other myocardiopathy. The inclusion will take place over a period of 24 months. No monitoring of patients (no follow-up) is provided under this protocol. The analysis will focus on the combination of the left ventricle myocardial deformations alteration revealed by the echocardiographic 2D strain analysis (< 18% in absolute value), with the existence of micro-angiopathy in type 1 diabetes mellitus patients with preserved left ventricular ejection fraction ( ≥ 60%).

Two hundred subjects with type 1 diabetes mellitus will be recruited: 100 subjects with impaired left ventricular myocardial deformation by 2D strain analysis (< 18% in absolute value), constituting the 'cases' group and 100 subjects without alteration in myocardial deformation (global strain ≥ 18%). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
