Introduction: Those with cardiac sarcoidosis (CS) are at risk of sudden cardiac death (SCD), which may be prevented using an implantable cardioverter–defibrillator (ICD). There are limited data available that follow the post-procedural outcomes of patients with cardiac sarcoidosis (CS) who have had an ICD implanted. Areas Covered: This review highlights studies that focused on both appropriate and inappropriate therapies in those with an ICD, as well as device complications in this group. There were several variables, including age, sex, ventricular characteristics, and findings on cardiac imaging that were investigated and discussed as influencing factors in predicting appropriate and inappropriate therapies. Conclusions: Adverse events in those with an ICD and CS have been minimally reported in the literature. Individuals diagnosed with CS are at high risk of ventricular arrhythmia, with comparable rates of appropriate therapy but with a higher incidence of side effects and inappropriate therapy. The younger average age of CS patients in comparison to other ICD cohorts warrants the need for further, large-scale, prospective trials with periodic interim follow-ups focused on those with this condition.

Introduction: Sarcoidosis is a systemic inflammatory disorder characterised by non-caseating granulomas. Cardiac sarcoidosis (CS) normally causes conduction abnormalities, ventricular arrhythmias, and heart failure. Little is known about the characteristics and impact of sarcoidosis in patients admitted with ST-elevation myocardial infarction (STEMI). This study aims to fill this void.Material and methods: Utilising the National Inpatient Sample (NIS) database (2016–2020), individuals with STEMI were identified and categorised based on sarcoidosis presence whilst adjusting for confounders via logistic regression models.Results: Among 851,290 STEMI patients, 1215 had sarcoidosis. Before propensity matching, sarcoidosis patients were notably different in demographics and comorbidities compared to non-sarcoidosis patients. After propensity score matching (PSM), sarcoidosis patients were found to have a higher incidence of supraventricular tachycardia (SVT) (2.5% vs. 1.3%, p = 0.024) and acute kidney injury (AKI) (23.3% vs. 20.8%, aOR = 1.269, 95% CI: 1.02–1.58, p = 0.033) but a lower incidence of undergoing coronary artery bypass graft (CABG) (5.5% vs. 8.5%, aOR = 0.663; 95% CI: 0.472–0.931, p = 0.018), while no significant disparities were noted in PCI, cardiogenic shock, mortality, or mean length of stay (LOS).Conclusions: Using propensity-matched large real-world data of STEMI patients, sarcoidosis was associated with fewer cases of CABG and a greater incidence of AKI and SVT compared to non-sarcoidosis patients.

Background Racial disparities in cardiovascular conditions are well documented. Whether similar race-based discrepancies in health outcomes also exist among elderly patients undergoing surgical aortic valve replacement (SAVR) for aortic stenosis remains understudied. Methods We abstracted data from the National (Nationwide) Inpatient Sample over a 20-year period from 2001 to 2020 using specific ICD-9 and ICD-10 codes. We included patients aged ≥ 60 and ≤ 80 years with races recorded as White, African American, or Hispanic at the time of their hospitalization for surgery. We analyzed and reported the baseline characteristics, risk-adjusted in-hospital mortality, and complications stratified by race. ResultsOf 420,181 patients studied, 90.0% identified as White, 4.0% as African American and 6.0% as Hispanic. Despite a decrease in overall in-hospital mortality rates from 3.8% between 2001-2005 to 1.8% between 2016-2020, African Americans had higher odds of all-cause in-hospital deaths compared to Whites (aOR = 1.390, P < 0.001). Additionally, they were more likely to experience cardiogenic shock (aOR = 1.241, P < 0.001) and acute kidney injury (aOR = 1.314, P < 0.001) as well as more likely to require organ support such as IABP use (aOR = 1.336, P < 0.001) or invasive mechanical ventilation (aOR = 1.342, P < 0.001). Interestingly, African Americans were less likely to report events of acute ischemic stroke compared to Whites (aOR = 0.852, P < 0.001). Conclusions Despite a reassuring reduction in overall in-hospital mortality rates of geriatric patients undergoing SAVR for aortic stenosis, racial disparities in health outcomes remain pervasive with minorities more likely to report higher in-hospital morbidity and mortality.
