Background: Depression has been identified as a risk factor for acute cerebrovascular events. Due to limited data focused on young females, we studied the burden and impact of comorbid depression on outcomes of acute ischemic stroke (AIS)-related admissions in young women of the reproductive age group. Methods: We used the National Inpatient Sample (2018) to identify admissions of young females (age 18-44 years) with AIS; and further classified it into two demographically (age, race, payer status, income) matched (1:1) groups based on the presence of comorbid depression. Comorbidities and outcomes were compared using relevant ICD-10 codes. Multivariable regression was used to analyze the association of comorbid depression with in-hospital mortality. Results: In 15850 young females admitted with AIS in 2018, 2465 (15.6%) had comorbid depression. Post-matching, the study cohort consisted of 4610 women admitted with AIS (Median age: 37, 66.2% whites) and 2305 women in each cohort, with and without depression. The matched AIS-depression arm often had younger women (median 37 vs 39 years), patients from the lower-income quartile (47.3% vs. 34.5%), and higher rates of obesity, peripheral vascular disease, and prior history of stroke but a lower prevalence of CVD risk factors [Table 1]. The depression arm had a non-significant odd of all-cause mortality (OR 1.32, 95%CI:0.64-2.74) when adjusted for sociodemographic confounders and comorbid risk factors (p=0.452). The LOS was shorter (median 4 vs 5 days) with comparable hospital charges in the depression arm vs. no depression arm (p<0.001). Conclusion: This study revealed a nearly 15% burden of depression in young females admitted for AIS without significant impact on all-cause mortality when controlled for confounders. The impact of depression on long-term AIS outcomes needs further evaluation.
Background: Mechanical thrombectomy (MT) has been proven to be a successful treatment option for patients with acute ischemic stroke (AIS) in numerous randomized controlled trials. The majority of trials underrepresent patients aged 70 and above, and there is little contemporary data on regional trends and variation in mortality. Methods: This retrospective study using the National Inpatient Sample (2016-2019) seeks to identify any regional relationships between geriatric patients' in-hospital mortality after MT for AIS at urban facilities and trends in inpatient mortality. Regional Inpatient mortality based on sex and race and trends between 2016 and 2019 were assessed. Results: Our study group consisted of 52455 AIS-MT admissions (median 78 yrs, 57.1% male, 77.2% white, 89.6% Medicare enrollees) with a 14.1% inpatient mortality rate. Despite having a lower comparative burden of traditional CVD risk factors, the hospitals from the Northeast had a higher inpatient mortality rate (17.2%, n=1650) and risk (adjusted OR:1.25, 95% CI:1.03-1.51) than the other regions. Similar trends were observed in male (18.1%), females (16.6%), white (17.3%) and black (13.8%) participants (P<0.001) undergoing AIS-MT. Highest inpatient mortality among Hispanics was linked to Midwest-based participants (16.2%) without regional variation in rates for Asians. There were declining trends in mortality between 2016 to 2019 in West region without any change in other regions (from 14.0% to 11.5%, ptrend=0.002) (Fig. 1) . Conclusion: Among demographically comparable geriatric patients with AIS undergoing MT in the US, the Northeast region admissions showed the highest inpatient mortality even after controlling for confounding factors with a relatively lower burden of CVD risk factors. This disparity warrants further research to validate these findings.
Background: Inpatient outcomes in obese patients have been investigated, although regional inequalities in cardiac and cerebrovascular events in young obese patients have not been explored previously. Methods: The National Inpatient Sample 2019 was queried for young obese patients (18-44 years) in 4 regions (Northeast, Midwest, South, West) using ICD-10-CM codes. Baseline characteristics and comorbidities inpatient MACCE including all-cause mortality, AMI, cardiac arrest, and stroke were identified. Results: Young obese cohort (Total n: 1,285,775, median age: 33 years, females: 75.4%) often consisted of admissions in the South (41.1%), followed by the Midwest (22.3%), West (20.7%), and Northeast (20.7%). HTN and DM were more frequent in the Midwest (32.3% and 22.3%) and South (34.4% and 22.8%) respectively, with higher MACCE of South (3.3%) and Midwest (3%) as compared to Northeast (2.3%) and West (2.6%) regions. All regions had comparable median hospital stay (3 days); however, the admissions in the West and Northeast regions (USD 36861 and 31211) had a higher cost burden. After adjusting for sociodemographic and comorbidities, the odds of in-hospital MACCE were higher in the West (aOR 1.15 95%CI 1.02-1.29), and South (aOR 1.16 95%CI 1.04-1.29), (p<0.001) vs. Northeast admissions (Fig. 1) . Conclusion: Cardiovascular comorbidities and MACCE were higher in young obese admissions in the South. This disparity may be due to differences in behavioral risk factors, socioeconomic status and healthcare access/prices. Future prospective studies on regional differences can help identify high-risk young, obese populations for targeted screening.
Background: Traditional cardiovascular disease (CVD) risk factors can increase the risk of Atrial Fibrillation (AF) even in young adults. With rising trends in CVD in the Asian population, we aimed to assess the prevalence and disparities of major modifiable risk factors for CVD and AF in the young Asians hospitalized in the US. Methods: The National Inpatient Sample (2016-2019) was used to estimate the temporal trends in modifiable CVD risk factors among young (18-44 years) Asian hospitalizations and evaluated disparities by sex. Also, we assessed the prevalence of AF in young Asians hospitalized with vs. without atleast one CVD risk factor. Results: From 2016 through 2019, a total of 1,324,259 young Asian admissions (Male 85%, age 18-44 years) were analyzed, the highest increase was noted for Obesity (1.8%) followed by Diabetes (1.3%). Males demonstrated the most prominent prevalence of Obesity (2.1%) and Hypertension (1.7%) as compared to the female population (1.7% and 0.4%), respectively. The incidence of AF in patients with at least one CVD risk factor increased by 0.4% (males 0.9% vs females 0.15%), (OR 2.80, 95%CI 2.44-3.21, p<0.001). Conclusion: The prevalence of modifiable risk factors for CVD are increasing at a steady pace in the young Asian population. There is a need for urgent preventive and curative strategies to decrease the overall burden of CVD in this population.
