Background: While spontaneous coronary artery dissection (SCAD) patients can present with ventricular arrhythmias (VAs), the in-hospital outcomes among these patients are not well-established. Objective: This study aimed to analyze the in-hospital outcomes of patients with SCAD and concurrent VAs, and to determine the predictors of VAs occurrence in this population. Methods: Using the Nationwide Readmissions Database, our study included patients aged 18 years or older who had SCAD between 2017 and 2020. We categorized the cohort into two groups depending on the presence of VAs during hospitalization. The in-hospital outcomes were assessed between two groups. Through multivariable analysis, we further analyzed the predictors of VAs occurrence among SCAD patients. Results: Our study included 160 (13.45%) SCAD patients with concurrent VAs and 1,030 (86.55%) SCAD patients without concurrent VAs between 2017 and 2020. SCAD patients with concurrent VA were associated with higher rates of early mortality (11.88% vs. 2.04%, p<0.01), prolonged index hospital stay (≥7 days) (31.25% vs. 12.82%, p<0.01), and non-home discharge (21.88% vs. 6.50%, p<0.01). The length of hospital stay was longer in the SCAD with concurrent VAs group (6.93 days vs. 3.73 days, p<0.01), and the median cumulative cost of hospitalization was also higher in this group ($31,450 vs. $14,664, p<0.01). SCAD with concurrent VAs patients also had poorer in-hospital adverse events. In multivariable analysis, the independent predictors for VAs occurrence among SCAD patients were chronic liver disease (aOR: 2.18; 95% CI: 1.15- 4.12, p=0.02) and heart failure (aOR: 3.40; 95%CI: 2.30- 5.02, p<0.01). Conclusion: Ventricular arrhythmias among SCAD patients were associated with poorer in-hospital outcomes. Heart failure and chronic liver disease were the predictors of VAs in SCAD patients. This highlights the importance of closely monitor and aggressive VAs management among these high-risk patients.

Background: While cardiac involvement in sarcoidosis could be significant, data assessing geographical disparities in cardiovascular deaths (CVDs) among patients with sarcoidosis are limited. Objective: This study aims to determine the mortality attributed to CVDs with comorbid sarcoidosis in different geographic locations in the United States. Methods: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database and performed serial cross-sectional analyses of national death certificate data for CVDs with comorbid sarcoidosis among patients aged 25 and above. Diseases of the circulatory system (ICD-10 I00-I99) were listed as the underlying cause of death, and sarcoidosis (ICD-10 D86) as contributing cause of death. We calculated age-adjusted mortality rates (AAMRs) per 1,000,000 individuals and compared the mortality among census regions and states. Results: In the 22-year study period, 5,630 CVDs with comorbid sarcoidosis in the United States were identified between 1999 and 2020. The South region had the highest AAMRs for CVDs with comorbid sarcoidosis (1.32 [95% CI, 1.26-1.37] per 1,000,000 individuals), followed by Northeast region (1.25 [95% CI, 1.18-1.32] per 1,000,000 individuals), Midwest region (1.24 [95% CI, 1.17-1.30] per 1,000,000 individuals), and West Region (0.92 [95% CI, 0.86-0.98] per 1,000,000 individuals). The AAMRs for CVDs with comorbid sarcoidosis were between 0.57 [95% CI, 0.43-0.75] per 1,000,000 individuals and 1.96 [95% CI, 1.73-2.19] per 1,000,000 individuals throughout the States, except Maryland and the District of Columbia, which recorded 2.79 [95% CI, 2.44-3.14] and 6.01 [95% CI, 4.44-7.94], respectively. Conclusion: The South region, particularly Maryland recorded the highest CVDs in sarcoidosis. Geographical disparities observed in CVDs with comorbid sarcoidosis highlight the need to improve public health measures at state-level.

Background: Sarcoidosis is a multisystem inflammatory disease that could result in debilitating cardiac manifestations. Despites, data on the cardiovascular deaths (CVDs) among patients with sarcoidosis are limited. Objective: This study sought to determine the longitudinal trends in mortality attributed to CVDs with comorbid sarcoidosis by age, sex, and race in the United States. Methods: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database and performed serial cross-sectional analyses of national death certificate data for CVDs with comorbid sarcoidosis among patients aged 25 and above. Diseases of the circulatory system (ICD-10 I00-I99) were listed as the underlying cause of death, and sarcoidosis (ICD-10 D86) as contributing cause of death. We calculated age-adjusted mortality rates (AAMRs) per 1,000,000 individuals and determined the trends over time by estimating the annual percent change using the Joinpoint Regression Program. Results: In the 22-year study period, 5,630 CVDs with comorbid sarcoidosis in the United States were identified between 1999 and 2020. The AAMRs from CVDs with comorbid sarcoidosis increased from 1.03 (95% CI, 0.88-1.17) in 1999 to 1.38 (95% CI, 1.24-1.52) in 2020. Overall, women recorded a higher AAMRs compared to men (1.25 [95% CI, 1.21-1.30] vs. 1.10 [95% CI, 1.06-1.15]). Black individuals had higher AAMRs than White individuals (5.17 [95% CI, 4.97-5.37] vs. 0.68 [95% CI, 0.66-0.71]). A higher percentage of CVDs with comorbid sarcoidosis was seen in the age groups of 55-64 in men (24.68%) and 65-74 in women (22.62%). Conclusion: The CVDs in sarcoidosis have increased over the last two decades, with disparities seen in women and Black individuals. Most CVDs with comorbid sarcoidosis occurred at a younger age compared to general population. This highlights the importance of early screening for cardiovascular diseases in sarcoidosis individuals.
