What's new in heart failure in the patient with type 2 diabetes?

Type 2 diabetes mellitus (T2DM) is considered an independent risk factor of heart failure (HF). It has been observed that diabetics have a higher risk of heart failure than non-diabetics. However, many aspects are still unknown; for example, the existence of a particular myocardiopathy common to T2DM, the pathogenesis of the HF associated with T2DM that is still not sufficiently clear, its role in the prognosis of HF, or the influence of anti-diabetic treatments on the outcome of the HF. An attempt is made in this review to summarise all those findings that have been published in the past 5 years as regards this interesting question, placing special emphasis on those questions still unresolved.
