Abstract

BACKGROUND:

It is unclear whether diabetes mellitus (DM) is an adverse prognostic factor in chronic heart failure (CHF) of ischaemic and non-ischaemic aetiology managed with contemporary evidence-based care.

METHODS:

In total, 1091 outpatients with CHF with reduced ejection fraction were prospectively observed for a mean of 960 days. Total and cardiovascular mortality was quantified after accounting for potential confounders.

RESULTS:

In total, 25.7% of patients had DM; this group was more likely to have CHF of ischaemic aetiology and was more symptomatic. Patients with DM received comparable medical- and device-based therapies, except for greater doses of loop diuretic. DM was associated with approximately doubled crude and adjusted risk of total and cardiovascular mortality. The association of diabetes with these outcomes in patients with ischaemic and non-ischaemic cardiomyopathies was of similar magnitude.

CONCLUSIONS:

In spite of advances in the management of CHF, DM remains a major adverse prognostic feature, irrespective of ischaemic/non-ischaemic aetiology.
