Background: Aortic stenosis (AS) imposes a significant mortality burden. Understanding demographic influences on the location of AS-related death is crucial for advancing equitable end-of-life care. Therefore, we investigated how demographic factors influence the location of death among AS patients in the United States. Methods: We completed a cross-sectional study utilizing US mortality data from the CDC’s WONDER database for 2019. All files related to decedents with AS identified as the primary cause of death were obtained, including demographic information and death locations (i.e., inpatient facilities, outpatient/ER facilities, home, or hospice/nursing facilities). Associations between demographic factors (age, sex, race/ethnicity, marital status, and education) and place of death were assessed using multivariable logistic regression models, yielding odds ratios (ORs). Results: In 2019, most AS-related deaths occurred in inpatient facilities (38.3%, n = 5062), home (29.2%, n = 3859), or hospice/nursing facilities (28.6%, n = 3775). Higher odds of inpatient death were observed among Black (OR 1.67, p < 0.001) and Hispanic individuals (OR 1.91, p < 0.001) compared to White decedents. Those aged >85 years were more likely to die at home (OR 1.76, p < 0.001) or in hospice/nursing facilities (OR 7.80, p < 0.001). Males had increased odds of inpatient death (OR 1.09, p = 0.044) but decreased odds of hospice/nursing facility death (OR 0.87, p = 0.003). Higher education levels were associated with increased odds of home death (OR 1.33, p = 0.023) and decreased odds of hospice/nursing facility death (OR 0.71, p = 0.015). Conclusions: Demographic factors significantly influence the location of death among AS patients, emphasizing the need for culturally and socioeconomically tailored interventions to promote equitable end-of-life care.

ABSTRACTBackgroundMyeloproliferative neoplasms (MPN) are associated with an increased cardiovascular risk including acute coronary syndrome. However, there is a lack of comprehensive data regarding the rate of percutaneous coronary intervention (PCI), as well as the in‐hospital characteristics and outcomes for MPN patients.AimsWe aimed to evaluate the temporal trends and outcomes of PCI among patients with MPN.Methods and ResultsThe National Inpatient Sample database from 2016 to 2020 was queried to identify all PCI hospitalizations. Temporal trends and outcomes of patients with and without MPN following PCI were analyzed. Propensity score matching (PSM) was implemented to compare outcomes between MPN and non‐MPN groups. 2,237,210 PCI hospitalizations with 7560 (0.27%) patients with MPN were included in this study. Throughout the study period, the prevalence of MPN among PCI admissions remained stable (p‐value for trend = 0.12). Within the MPN subgroup, essential thrombocythemia (ET) was the predominant condition (53.2). Patients with MPN had higher prevalence of cardiovascular comorbidities than non‐MPN patients. Following PSM, MPNs were significantly associated with a higher risk of blood transfusions (OR: 1.66, 95% CI: 1.22−2.24, p = 0.001) and AKI (OR: 1.39, 95% CI: 1.17−1.65, p < 0.001). In contrast, the risk of in‐hospital mortality (OR: 1.18, 95% CI: 0.83−1.69, p = 0.354 and bleeding (OR: 1.43, 95% CI: 0.90−2.27, p = 0.127) did not significantly differ between the two groups.ConclusionsOur study demonstrated that while the prevalence of MPN among patients undergoing PCI remained stable, those with MPN faced higher risks of bleeding, blood transfusion and acute kidney injury. Further research is warranted to explore the underlying reasons for these increased risks and to improve outcomes in this high‐risk group.

Abstract Introduction Gastrointestinal bleeding (GIB) is often encountered among patients with atrial fibrillation (AF) due to the use of anticoagulation. This study assesses disparities in GIB‐related mortality among decedents with AF in the United States. Methods GIB mortality data in patients with AF from 1999 to 2020 was queried from the CDC database. Decedent demographic information (age, sex, race and ethnicity, and geographic residence) was obtained from death certificates. We calculated age‐adjusted mortality rates (AAMRs) through the direct method and estimated the annual percentage change (APC) in mortality using log‐linear regression models. Results From 11,209 GIB‐related deaths among AF decedents, we observed an increase in AAMR from 0.12 in 1999 to 0.21 in 2020, particularly during the 2009 to 2020 period (APC +4.8, p < .001). Disproportionate mortality rates were noted in males (AAMR 0.18) and White populations (AAMR 0.15) as compared to females (AAMR 0.13) and Black populations (AAMR 0.10), respectively. Rural regions also reported higher mortality (AAMR 0.18) than urban areas (AAMR 0.14). Mortality shifts in urban regions remained stagnant from 1999 to 2009 (APC –0.15, p = .806) followed by an increase from 2009 to 2020 (APC +4.83, p < .001). However, mortality increased consistently from 1999 to 2020 in rural regions (APC +4.08, p < .001). The Northeast US exhibited the highest mortality rate (AAMR 0.18), followed by the Midwest (AAMR 0.16), West (AAMR 0.14), and South (AAMR 0.13). Conclusions Disparities in GIB mortality among AF decedents were identified. These findings accentuate the need for targeted interventions to mitigate GIB risks in vulnerable subgroups.

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 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.

Stenosis of the left main coronary artery (LM stenosis) is associated with significant mortality and morbidity due to the large area of affected myocardium. Evidence on the use of percutaneous coronary intervention (PCI) for the treatment of LM stenosis is growing. However, the role of Western guidelines on patients in the Asian-Pacific region is unclear due to anatomical variations, substantial heterogeneity in healthcare resources and infrastructure, and the lack of consensus on the optimal management of LM stenosis in the Asia-Pacific region. Hence, an Asian Pacific Society of Cardiology (APSC) working group developed consensus recommendations on the use of PCI in the management of LM stenosis in the Asia-Pacific region. The APSC expert panel reviewed and appraised the available evidence using the Grading of Recommendations Assessment, Development, and Evaluation system. Consensus recommendations were developed and put to an online vote. Consensus was reached when 80% of votes for a given recommendation were in support of ‘agree’ or ‘neutral’. The resulting 12 statements provide guidance for clinical practitioners in the region on the use of PCI in the treatment of patients with LM stenosis.

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.

Background Although myocardial infarction with nonobstructive coronary arteries (MINOCA) is more common in women, it is unknown whether sex is a risk factor for adverse outcomes in patients with MINOCA. We aimed to investigate the relationship between sex differences and outcomes of patients with MINOCA. Methods and Results A systematic literature search was performed in PubMed, Embase, and Cochrane databases from their inception until August 2023 for relevant studies. End points were pooled using the Hartung–Knapp–Sidik–Jonkman random‐effects model as odds ratio (OR) with 95% CIs. Nine studies, involving 30 281 patients with MINOCA (comprising 18 079 women and 12 202 men), were included in the study. Women were older and had a higher prevalence of hypertension, diabetes, and stroke compared with men. The median duration of follow‐up was 3.5 years, with an interquartile range of 2.2 to 4.2 years. Pooled analysis revealed no statistically significant difference in the risk of all‐cause mortality (OR, 1.03 [95% CI, 0.87–1.22]), major adverse cardiovascular events (OR, 1.18 [95% CI, 0.89–1.58]), heart failure (OR, 1.32 [95% CI, 0.57–3.03]), stroke (OR, 1.13 [95% CI, 0.56–2.26]), and myocardial infarction (OR, 1.04 [95% CI, 0.29–3.76]) between the 2 groups. Regarding short‐term outcomes, women had a significantly higher risk of in‐hospital major adverse cardiovascular events compared with men (OR, 1.33 [95% CI, 1.16–1.53]) whereas there was no significant difference in the risk of in‐hospital mortality (OR, 0.90 [95% CI, 0.64–1.28]) between the 2 patient groups. Conclusions Despite the differences in demographics and comorbidity profiles, there was no significant difference in the long‐term outcomes for patients with MINOCA between sexes. However, it is noteworthy that women experienced a higher risk of in‐hospital major adverse cardiovascular events compared with men.

Abstract Aims Lipoprotein(a) [Lp(a)] has demonstrated its association with atherosclerosis and myocardial infarction. However, its role in the development of in-stent restenosis (ISR) after percutaneous coronary intervention (PCI) is not clearly established. The aim of this study is to investigate the association between Lp(a) and ISR. Methods and results A retrospective study of adult patients who underwent successful PCI between January 2006 and December 2017 at the three Mayo Clinic sites and had a preprocedural Lp(a) measurement was conducted. Patients were divided into two groups according to the serum Lp(a) concentration [high Lp(a) ≥ 50 mg/dL and low Lp(a) &lt; 50 mg/dL]. Univariable and multivariable analyses were performed to compare risk of ISR between patients with high Lp(a) vs. those with low Lp(a). A total of 1209 patients were included, with mean age 65.9 ± 11.7 years and 71.8% were male. Median follow-up after baseline PCI was 8.8 [interquartile range (IQR) 7.4] years. Restenosis was observed in 162 (13.4%) patients. Median serum levels of Lp(a) were significantly higher in patients affected by ISR vs. non-affected cases: 27 (IQR 73.8) vs. 20 (IQR 57.5) mg/dL, P = 0.008. The rate of ISR was significantly higher among patients with high Lp(a) vs. patients with low Lp(a) values (17.0% vs. 11.6%, P = 0.010). High Lp(a) values were independently associated with ISR events (hazard ratio 1.67, 95% confidence interval 1.18–2.37, P = 0.004), and this association was more prominent after the first year following the PCI. Conclusion Lipoprotein(a) is an independent predictor for long-term ISR and should be considered in the evaluation of patients undergoing PCI.

Cardiogenic shock is the most common cause of mortality in patients with acute myocardial infarction with an increase in incidence over the last 15-years. Recent classification systems of cardiogenic shock (CS) have improved categorization of patients into subsets of acuity and begun to integrate phenotypes and etiologies in addition to risk modifiers. Early revascularization with PCI or CABG has been the most important advance in the management of AMI-CS patients with improvements in survival. Despite this initial progress, mortality remains high at approximately 40%, with a significant proportion of patients dying of neurological causes, especially in the cohort with cardiac arrest and multi-organ dysfunction despite cardiac recovery. Mechanical circulatory support devices are an attractive strategy to ameliorate the cardio-metabolic spiral but have thus far failed to show survival benefits in randomized trials during revascularization of AMI-CS patients with IABP and ECMO use, although many aspects of their use have yet to be studied, including their role as part of an escalation or bridging strategy along the continuum of CS care. Randomized trials in Impella percutaneous LVAD use are pending. Cardiac arrest patients represent an important cohort with specific challenges of care and familiarity with management including the use of mechanical CPR devices, temperature optimization, MCS use and pharmacotherapy issues are critical to successful outcomes.
