The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 has affected the health of people across the globe. Cardiovascular diseases (CVDs) have a significant relationship with COVID-19, both as a risk factor and prognostic indicator, and as a complication of the disease itself. In addition to predisposing to CVD complications, the ongoing pandemic has severely affected the delivery of timely and appropriate care for cardiovascular conditions resulting in increased mortality. The etiology behind the cardiac injury associated with severe acute respiratory syndrome coronavirus-2 is likely varied, including coronary artery disease, microvascular thrombosis, myocarditis, and stress cardiomyopathy. Further large-scale investigations are needed to better determine the underlying mechanism of myocardial infarction and other cardiac injury in COVID-19 patients and to determine the incidence of each type of cardiac injury in this patient population. Telemedicine and remote monitoring technologies can play an important role in optimizing outcomes in patients with established CVD. In this article, we summarize the various impacts that COVID-19 has on the cardiovascular system, including myocardial infarction, myocarditis, stress cardiomyopathy, thrombosis, and stroke.
Background
Inflammatory bowel disease (IBD) is associated with an increased acute coronary syndrome (ACS) risk. Data are limited regarding the epidemiology and outcomes of ACS in patients with IBD.
Methods
A retrospective cohort analysis of patients with IBD admitted for ACS in the U.S. Healthcare Cost and Utilization Project National Inpatient Sample for 2005 to 2015 was conducted. We analyzed trends in IBD-ACS admissions and mortality, differences in risk profiles, management strategies, and in-hospital mortality between IBD-ACS and non-IBD ACS and between ulcerative colitis (UC) and Crohn disease (CD).
Results
We studied 6,872,415 non-IBD ACS and 24,220 IBD-ACS hospitalizations (53% with CD). During the study period, the number of hospitalizations for IBD-ACS increased, particularly those related to CD. Compared with non-IBD ACS, patients with IBD-ACS had a lower prevalence of cardiovascular risk factors and similar rates of coronary angiography and revascularization. The in-hospital mortality rate was lower with IBD-ACS (3.9%) compared with non-IBD ACS (5.3%; odds ratio, 0.81; 95% confidence interval, 0.69-0.96; P = 0.011) and was stable between 2005 and 2015. Risk factors, ACS management strategies, and mortality were similar between CD and UC. Coagulopathy, weight loss, and gastrointestinal bleeding were more frequent in IBD-ACS and were strong independent predictors of mortality.
Conclusions
Hospitalizations for ACS in patients with IBD increased in recent years but death rates were stable. The ACS-related risk profiles and mortality were modestly favorable with IBD-ACS than with non-IBD ACS and were similar between CD and UC. Complications more frequently associated with IBD were strongly associated with mortality. These findings indicate that aggressive management of IBD and ACS comorbidities is required to improve outcomes.
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.
