Introduction: Stroke-related mortality poses significant challenges in the US. Increased at-home deaths since COVID-19 pandemic prompted changes in the provision of end-of-life care. Question: What were the settings of stroke deaths in the US during COVID-19 pandemic? Methods: Decedent-level mortality data from death certificates in CDC repository were obtained for the year 2020 (pandemic) and 2019 (comparison). Demographic data include age, sex, race/ethnicity, education, marital status, and place of stroke death, including inpatient, outpatient/emergency room (ER), hospice/nursing facilities (H/NF), and at-home. Multivariable logistic regression models assessed demographic impact on stroke mortality by place-of-death, yielding odds ratios (OR) with significance threshold of p<0.05. Results: A total of 5,400 and 5,712 stroke-related deaths occurred in 2019 and 2020, respectively. During COVID-19, decedents >65 years were more likely to die in H/NF (OR 10.05, p<0.001) but less likely in outpatient/ER (OR 0.32, p<0.001) or at home (OR 0.57, p=0.007) compared to those <35 years. High education level did not significantly influence the place of death than having high school diploma or less (p>0.05). Males were more likely to die at home (OR 1.38, p<0.001) but less likely as inpatient (OR 0.79, p<0.001) than females. Hispanic decedents had a higher likelihood of inpatient death (OR 1.22, p=0.041) but less likely to die in H/NF (OR 0.55, p<0.001) compared to non-Hispanic decedents. Compared to White decedents, Black decedents were more likely to die in outpatient/ER (OR 1.44, p=0.018), while American Indian decedents were more likely to die as inpatient (OR 3.12, p=0.005). Asian/Pacific Islander decedents had a higher chance of inpatient death (OR 1.47, p=0.002) but a lower likelihood of dying in H/NF (OR 0.61, p=0.010). Married decedents were more likely than singles to die as inpatient (OR 1.37, p=0.001) or in outpatient/ER (OR 1.99, p<0.001), but less likely to die in H/NF (OR 0.61, p=0.002) or at home (OR 0.56, p<0.001). Conclusion: Our analysis revealed the influence of demographics on the settings of stroke fatalities during the COVID-19 pandemic. Further investigation is needed to determine contributing factors.

Background Hyperlipidemia is a major cardiovascular disease (CVD) risk factor, but there are limited data on its mortality trends in CVD over time. We assessed annual hyperlipidemia‐related CVD mortality trends in the United States, including the COVID‐19 pandemic's impact. Methods and Results Mortality data were obtained from the Centers for Disease Control and Prevention repository between 1999 and 2020 among patients ≥15 years old, using International Classification of Diseases, Tenth Revision ( ICD‐10 ) codes for hyperlipidemia (E78.0–E78.5) and CVD (I00–I99). Age‐adjusted mortality rates (AAMRs) per 1 000 000 population were standardized to the 2000 US population. Log‐linear regression models were used to evaluate mortality shifts. Average annual percentage change from 1999 to 2019 was used to project 2020 AAMRs, estimating pandemic‐attributed excess deaths. From 1999 to 2020, 483 155 hyperlipidemia‐related CVD deaths occurred. Despite a general CVD mortality decline, hyperlipidemia‐related CVD AAMRs rose from 36.33 in 1999 to 99.77 in 2019. Ischemic heart diseases (AAMR 49.39) were the leading cause, whereas hypertension had the highest mortality increase (average annual percentage change +10.23%). Mortality rates were higher in men (AAMR 104.87) and non‐Hispanic (AAMR 82.49), and rural populations (AAMR 89.98). Highest mortality was observed in Black populations (AAMR 84.35), those ≥75 years old (AAMR 646.45), and Western US regions (AAMR 96.88). During the first pandemic year, deaths exceeded projections by 10.55%, with notable increases among ages 35 to 75 (14.23%), Hispanic (17.96%), Black (14.82%), and urban (11.68%) groups. Conclusions Hyperlipidemia‐related CVD mortality has risen over the past 2 decades, further heightened by the COVID‐19 pandemic, with higher impact on men, Black Americans, the older population, and rural residents. Further study is needed to understand contributing factors and mitigate disparities.

Background Peripartum cardiomyopathy (PPCM) outcomes have been previously linked to demographic and social factors. The social vulnerability index (SVI) is a measure of social vulnerability in the United States. We explored PPCM disparities and the impact of SVI on PPCM mortality. Methods and Results Mortality from 1999 to 2020, SVI, and demographic data were obtained from CDC databases. County‐specific SVI rankings were linked to PPCM age‐adjusted mortality rates (AAMRs), allowing for a comparative analysis of AAMRs across both cumulative populations and subpopulations to identify disparities. All US counties were then stratified into low‐ and high‐SVI groups, facilitating comparison of SVI rankings by estimation of excess‐deaths per 1 000 000 person‐years attributable to greater social vulnerability and rate ratios (RR) through univariable Poisson regression. We identified a total of 1026 deaths related to PPCM between 1999 and 2020. Overall AAMR increased from 0.180 in 1999 to 0.326 in 2020. Black populations (AAMR: 1.081) and Southern US counties (AAMR: 0.444) had the highest AAMRs compared with other racial and US census groups, respectively. Higher SVI accounted for 0.172 excess deaths per 1 000 000 person‐years (RR=1.800). Among Black and White populations, higher SVI also accounted for 0.248 and 0.071 excess deaths per 1 000 000 person‐years, respectively. Similar impacts of greater social vulnerability were observed when comparing the US census regions (Northeast RR=1.609, Midwest RR=1.819, South RR=1.934, West RR=1.776). Conclusions PPCM mortality disparities exist across racial and geographic populations in the United States. A greater burden of social vulnerability is associated with higher PPCM mortality on a national level.

Heart failure with preserved ejection fraction (HFpEF) includes almost half of heart failure cases typified by a specific clinical syndrome. Despite diagnostic and management advances, HFpEF still presents a diagnostic challenge and a paucity of therapies specifically aimed at enhancing survival and improving quality of life is still lacking. This review elucidates the diagnostic complexity of HFpEF, highlighting the use of both subjective and objective criteria within algorithmic frameworks. It also examines the significant impact of comorbidities on the progression of HFpEF. Additionally, we explore the latest evidence on targeting these comorbidities therapeutically, although the benefits to mortality are still limited.

Antithrombotic treatment in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) poses a dilemma. We compared outcomes of dual antithrombotic therapy (DAT) (direct oral anticoagulants (DOACs)/warfarin + antiplatelets) vs triple antithrombotic therapy (TAT) (DOACs/warfarin, aspirin, and P2Y12 inhibitor) in this population. Multiple databases were searched from inception to December 17, 2023 to identify randomized controlled trials (RCTs) comparing DAT vs TAT in patients with AF and ACS. Outcomes included major adverse cardiac events (MACE), bleeding events, stroke, stent thrombosis, and myocardial infarction (MI). Relative risk and 95% confidence intervals were estimated with a random-effects model using the inverse-variance technique. We assigned I 2 > 50% as an indicator of statistical heterogeneity. p -Value <0.05 was considered significant. Ten RCTs comprising 6186 patients on TAT (female 26%, mean age 71 ± 9 years) and 6800 patients on DAT (female 27%, mean age 71 ± 9 years) were included. Patients receiving DAT experienced lower rates of bleeding events compared to those receiving TAT, with relative risks of 0.69 [0.55–0.87] ( p < 0.001), 0.65 [0.40–1.06] ( p = 0.09), and 0.62 [0.46–0.84] ( p < 0.001) for TAT durations of 3, 6, and 12 months, respectively. No difference was seen in the occurrence of MACE, MI, stroke, or stent thrombosis between DAT and TAT across all three durations of TAT. This is the largest pooled analysis comparing TAT to DAT stratified by the duration of antithrombotic therapy. Our results revealed that DAT was associated with reduced bleeding risk despite no difference in other outcomes.

AbstractBackgroundThe impact of chronic kidney disease (CKD) on atrial fibrillation outcomes (AF) is not well understood.MethodsWe conducted analyses of comorbid AF and CKD related death in the United States from 1999 to 2020 using descriptive epidemiology.ResultsAge‐adjusted mortality rates (AAMR) per 100,000 increased from 0.39 in 1999 to 1.65 in 2020. Non‐Hispanic populations (1.01) and nonmetropolitan areas (1.08) had higher AAMRs compared to Hispanic (0.62) and metropolitan (0.97) areas. Midwestern (1.11) and Western (1.13) US regions recorded the highest AAMRs.ConclusionsThese findings highlight the need for interventions to address AF death disparities in patients with CKD.

Background: Non-Hodgkin lymphoma (NHL) survivors are at increased risks of cardiovascular disease related death (CVD) compared to the general population. Objective: This study sought to determine the longitudinal trends in mortality attributed to CVD with comorbid NHL by race, sex, and geographic location. Methods: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among patients aged 18 and above from 1999 to 2020. Patients were identified when the primary causes of death were ischemic heart diseases (ICD 10 I20-I25), cerebrovascular diseases (I60-I69), or hypertensive disease (I10-I15), and NHL (C82-C85) was a 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, a total of 22,778 CVD with comorbid NHL were identified. Overall, there was a significant decrease in annual trends for the AAMRs of CVD from 6.91 per 1,000,000 individuals in 1999 to 4.12 per 1,000,000 individuals in 2020 (p<0.05), with an annual percent decrease of 3.3. Overall, men recorded a higher AAMRs compared to women (6.76 vs 3.45, p<0.05). When stratified by race, White individuals had the highest AAMRs (5.07), while the AAMRs for American African, Asian, American Indian individuals were 3.01, 2.77, and 2.48 per 1,000,000 individuals respectively. The AAMRs were higher in the rural region than in the urban region (4.97 vs 4.78, p<0.05). Among all consensus regions, South region had the highest AAMRs. Conclusion: In conclusion, our study revealed a significant decrease in cardiovascular disease related deaths with comorbid NHL over the past two decades. It provides valuable insights into the effectiveness of management of comorbid CVD or CVD risk factors in patients with NHL.

AbstractBackgroundCardiac arrest (CA) is a leading cause of death in the United States (US). Social determinants of health may impact CA outcomes. We aimed to assess mortality trends, disparities, and the influence of the social vulnerability index (SVI) on CA outcomes in the young.MethodsWe conducted a cross‐sectional analysis of age‐adjusted mortality rates (AAMRs) related to CA in the United States from the Years 1999 to 2020 in individuals aged 35 years and younger. Data were obtained from death certificates and analyzed using log‐linear regression models. We examined disparities in mortality rates based on demographic variables. We also explored the impact of the SVI on CA mortality.ResultsA total of 4792 CA deaths in the young were identified. Overall AAMR decreased from 0.20 in 1999 to 0.14 in 2020 with an average annual percentage change of −1.3% (p = .001). Black (AAMR: 0.30) and male populations (AAMR: 0.14) had higher AAMR compared with White (AAMR: 0.11) and female (AAMR: 0.11) populations, respectively. Nonmetropolitan (AAMR: 0.29) and Southern (AAMR: 0.26) regions were also impacted by higher AAMR compared with metropolitan (AAMR: 0.11) and other US census regions, respectively. A higher SVI was associated with greater mortality risks related to CA (risk ratio: 1.82 [95% CI, 1.77–1.87]).ConclusionsOur analysis of CA in the young revealed disparities based on demographics, with a decline in AAMR from 1999 to 2020. There is a correlation between a higher SVI and increased CA mortality risk, highlighting the importance of targeted interventions to address these disparities effectively.

Peripartum cardiomyopathy is an idiopathic cardiomyopathy that most commonly affects women in the third trimester of pregnancy or in the first five months of the postpartum period. Peripartum cardiomyopathy is associated with a myriad of different findings on electrocardiograms. There is also a risk of supraventricular tachycardia, atrial fibrillation, atrial flutter, and ventricular arrhythmias. This review discusses the prevalence and management of tachyarrhythmias and bradyarrhythmias in peripartum cardiomyopathy.
