Clinical Trial Summary

The present project aims to investigate if the empagliflozin has an antiarrhythmic action. Analyzing the T-wave heterogeneity index, a new electrocardiographic risk marker associated with the prediction of cardiovascular risk, in diabetic patients and coronary artery disease, the investigators will verify if empagliflozin is associated with a reduction in electrical instability.

Description:

Cardiovascular diseases are the leading cause of morbidity and mortality in diabetic patients. New hypoglycemic drugs are required to undergo cardiovascular safety studies for their release. In 2015, EMPA-REG OUTCOME, which was done for empagliflozin´s approval was the first study to provide evidence that an antidiabetic agent could decrease cardiovascular events. The results demonstrated a reduction in the primary outcome (death by cardiovascular causes, nonfatal infarction, and nonfatal stroke), cardiovascular mortality and hospitalization for heart failure in patients with type 2 diabetes at high cardiovascular risk who received empagliflozin in combination with standard treatment. It is noteworthy that the study population was under-optimized clinical treatment with antihypertensives, statin and aspirin and especially it is noteworthy that the difference in the primary outcome over placebo became evident only three months after treatment´s start. The potential mechanisms underlying the surprising cardiovascular benefits of empagliflozin are not fully understood. The present project aims to investigate if the empagliflozin has an antiarrhythmic action. Analyzing the T-wave heterogeneity index, a new electrocardiographic risk marker associated with the prediction of cardiovascular risk, in diabetic patients and coronary artery disease, we will verify if empagliflozin is associated with a reduction in electrical instability.
