Background
Takotsubo cardiomyopathy is a non-ischemic cardiomyopathy characterized by acute left ventricular systolic dysfunction with transient wall motion abnormalities without a culprit coronary stenosis or other concurrent diagnoses. Its coexistence with transient high-degree AV block is very infrequent.
Case presentation
A 61-year-old man presented with a new onset of high degree AV block without ST segment deviations developing an anterior and apical dyskinesia with a low left ventricular ejection fraction in the absence of coronary artery disease.
Conclusion
Atrioventricular block is an uncommon presentation of Takotsubo syndrome. The management of patients with relevant conduction disorders in this scenario is a challenge for the clinician. In case of persistence of advanced conduction disorders, it seems appropriate to implant a pacemaker.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
