BACKGROUND: During COVID-19 pandemic, elective invasive cardiac procedures (ICP) have been frequently cancelled or postponed . Consequences may be more evident in patients with diabetes.
OBJECTIVES: The objective was to identify the peculiarities of patients with DM among those in whom ICP were cancelled or postponed due to the COVID-19 pandemic, as well as to identify subgroups in which the influence of DM has higher impact on the clinical outcome .
METHODS: We included 2,158 patients in whom an elective ICP was cancelled or postponed during COVID-19 pandemic in 37 hospitals in Spain . Among them , 700 (32.4 %) were diabetics . Patients with and without diabetes were compared .
RESULTS: Patients with diabetes were older and had a higher prevalence of other cardiovascular risk factors, previous cardiovascular history and co-morbidities . Diabetics had a higher mortality (3.0% vs. 1.0% ; p = 0.001) and cardiovascular mortality (1.9% vs. 0.4% ; p = 0.001). Differences were especially important in patients with valvular heart disease (mortality 6.9% vs 1.7% [p <0.001] and cardiovascular mortality 4.9% vs 0.9% [p = 0.002] in patients with and without diabetes, respectively). In the multivariable analysis, diabetes remained as an independent risk factor both for overall and cardiovascular mortality . No significant interaction was found with other clinical variables .
CONCLUSION: Among patients in whom an elective invasive cardiac procedure is cancelled or postponed during COVID-19 pandemic, mortality and cardiovascular mortality is higher in patients with diabetes, irrespectively on other clinical conditions . These procedures should not be cancelled in patients with diabetes.
