Cardiogenic diabetes

It has been well established since the Framingham studies that diabetes mellitus is a risk factor for heart failure. Several recent reports suggested that the reverse is also true, and heart failure may also predispose to diabetes. We reviewed the literature and summarized the evidence of a higher incidence of new-onset diabetes in heart failure. Because a high rate of insulin resistance in heart failure is a known phenomenon, a higher incidence of diabetes in heart failure is intuitive. Although the facts confirming such connection is surprisingly scarce, we felt it was important to collect, analyze, and summarize the evidence.
