Does diabetes mellitus or prediabetes mellitus increase the risk of mortality and cardiovascular hospitalization in patients with chronic heart failure?
In patients with chronic heart failure, diabetes mellitus, but not prediabetes, is independently associated with an increased risk of all-cause death and cardiovascular hospitalization.
Effect estimate: HR 1.43 (95% CI 1.28-1.60)
Absolute Event Rate: 34.5% vs 24.6%
p-value: p=<0.0001
BACKGROUND: The independent prognostic impact of diabetes mellitus (DM) and prediabetes mellitus (pre-DM) on survival outcomes in patients with chronic heart failure has been investigated in observational registries and randomized, clinical trials, but the results have been often inconclusive or conflicting. We examined the independent prognostic impact of DM and pre-DM on survival outcomes in the GISSI-HF (Gruppo Italiano per lo Studio della Sopravvivenza nella Insufficienza Cardiaca-Heart Failure) trial. METHODS AND RESULTS: We assessed the risk of all-cause death and the composite of all-cause death or cardiovascular hospitalization over a median follow-up period of 3.9 years among the 6935 chronic heart failure participants of the GISSI-HF trial, who were stratified by presence of DM (n=2852), pre-DM (n=2013), and non-DM (n=2070) at baseline. Compared with non-DM patients, those with DM had remarkably higher incidence rates of all-cause death (34.5% versus 24.6%) and the composite end point (63.6% versus 54.7%). Conversely, both event rates were similar between non-DM patients and those with pre-DM. Cox regression analysis showed that DM, but not pre-DM, was associated with an increased risk of all-cause death (adjusted hazard ratio, 1.43; 95% CI, 1.28-1.60) and of the composite end point (adjusted hazard ratio, 1.23; 95% CI, 1.13-1.32), independently of established risk factors. In the DM subgroup, higher hemoglobin A1c was also independently associated with increased risk of both study outcomes (all-cause death: adjusted hazard ratio, 1.21; 95% CI, 1.02-1.43; and composite end point: adjusted hazard ratio, 1.14; 95% CI, 1.01-1.29, respectively). CONCLUSIONS: Presence of DM was independently associated with poor long-term survival outcomes in patients with chronic heart failure. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.

Dauriz et al. (Sat,) conducted a cohort in Chronic heart failure (n=6,935). Diabetes mellitus vs. Non-diabetes mellitus was evaluated on All-cause death (HR 1.43, 95% CI 1.28-1.60, p=<0.0001). Diabetes mellitus was independently associated with a 43% increased risk of all-cause death (HR 1.43) compared to non-diabetes in patients with chronic heart failure.
