Has mortality in the United States returned to pre-pandemic levels? An analysis of provisional 2023 data.

BACKGROUND: The COVID-19 pandemic, which started in 2020, resulted in greater all-cause mortality in 2020 and in subsequent years. Whether all-cause mortality remains elevated in 2023 compared to pre-pandemic numbers is unknown. METHODS AND RESULTS: The United States (US) Center for Disease Control Wide-Ranging, Online Data for Epidemiologic Research database was used to compare mortality rates between 2019 and provisional data for 2022 and 2023. Age-adjusted mortality rates (AAMRs) for all-cause as well as top causes of mortality were collected. Mortality based on subgroups by sex, age, and ethnicity was also collected. All-cause AAMRs between 2018 and 2023 per 100,000 individuals were 723.6, 715.2, 835.4, 879.7, (provisionally) 798.8, and (provisionally) 738.3, respectively, with AAMRs in 2023 remaining above 2019 pre-pandemic levels. Similar trends were noted in subgroups based on sex, ethnicity, and most age groups. Mortality attributed directly to COVID-19 peaked in 2021 as the 3rd leading cause of death and dropped to the 10th leading cause in 2023. Provisional mortality rate trends for 2023 suggest that rates for diseases of the heart increased during the pandemic but appear to have returned to or dipped below pre-pandemic levels. CONCLUSION: Provisional 2023 all-cause mortality rates in the US have decreased from the 2021 peak associated with the COVID-19 pandemic but remain above the pre-pandemic baseline. Mortality from some conditions, including diseases of the heart, appears to have recovered from the impact of the COVID-19 pandemic.

Highlights of Cardiovascular Disease Prevention Studies Presented at the 2024 American College of Cardiology Conference.

PURPOSE OF REVIEW: To summarize selected late-breaking science on cardiovascular (CV) disease prevention presented at the 2024 Scientific Session of the American College of Cardiology (ACC) conference. RECENT FINDINGS: The LIBerate-HR trial showed the efficacy and safety of lerodalcibep, a subcutaneous injection that prevents binding of Pro-Protein Convertase Subtilisin/Kexin (PCSK) 9 to low-density lipoprotein (LDL)-receptors resulting in LDL-cholesterol (LDL-C) lowering in patients at very high risk or high risk of atherosclerotic CV disease (ASCVD). The AEGIS-II randomized patients with type 1 myocardial infarction (MI) with multivessel coronary artery disease and additional CV risk factors and found no benefit in major adverse CV events (MACE) with CSL112, an apolipoprotein A1 infusion shown to increase cholesterol efflux capacity. The Bridge-TIMI 73a trial showed a significant reduction in triglyceride (TG) levels with olezarsen, an antisense mRNA, in patients with moderate hyperTG with elevated CV risk. The BE ACTIVE trial showed significant improvement in step counts in patients given behavioral and financial incentives. The DRIVE study showed a significant increase in the prescription of either sodium-glucose co-transporter-2 inhibitors or glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes mellitus (T2DM) at elevated CV or renal risk with a remote team-based, non-licensed navigator and clinical pharmacist approach. The TACTiC trial showed increased and sustained use of statin therapy by patient-driven use of a web-based portal that calculated the ASCVD risk score and gave prompts. The VICTORIAN-INITIATE trial showed efficacy and safety in early use of inclisiran in patients with ASCVD who did not reach target LDL-C < 70 mg/dL despite maximally tolerated statin therapy. The ARISE-HF trial showed no difference in change of peak oxygen consumption with the use of an oral aldose reductase inhibitor, AT-001, in patients with well-controlled T2DM and diabetic cardiomyopathy with high-risk features compared to placebo. The PREVENT trial showed a significant reduction in target vessel failure at 2 years in patients with non-flow limiting vulnerable plaques with percutaneous coronary intervention and optimal medical therapy (OMT) compared to OMT alone. The late-breaking clinical science presented at the 2024 Scientific Session of the ACC paves the way for an evidence-based alternative to statin therapy and provides data on several common clinical scenarios encountered in daily practice.

Highlights of Cardiovascular Disease Prevention Studies Presented at the 2023 American Heart Association Scientific Sessions.

PURPOSE OF REVIEW: Focused review highlighting ten select studies presented at the 2023 American Heart Association (AHA) Scientific Sessions. RECENT FINDINGS: Included studies assessed semaglutide and cardiovascular outcomes in overweight or obese patients without diabetes (SELECT); dapagliflozin in patients with acute myocardial infarction without diabetes (DAPA-MI); effects of dietary sodium on systolic blood pressure in middle-aged individuals (CARDIA-SSBP); long-term blood pressure control after hypertensive pregnancy with physician guided self-management (POP-HT); effect and safety of zilebesiran, an RNA interference therapy, for sustained blood pressure reduction (KARDIA-1); recaticimab add-on therapy in patients with non-familial hypercholesterolemia and mixed hyperlipidemia (REMAIN-2); efficacy and safety of lepodisiran an extended duration short-interfering RNA targeting lipoprotein(a); safety and pharmacodynamic effects of an investigational DNA base editing medicine that inactivates the PCSK9 gene and lowers LDL cholesterol (VERVE-101); automated referral to centralized pharmacy services for evidence-based statin initiation in high-risk patients; and effects of intensive blood pressure lowering in reducing risk of cardiovascular events (ESPRIT). Research presented at the 2023 AHA Scientific Sessions emphasized innovative strategies in cardiovascular disease prevention and management.

Expectant management of patent ductus arteriosus for preterm infants: A meta-analysis of randomized controlled trials.

We conducted this meta-analysis to compare expectant management of patent ductus arteriosus (PDA) with active treatment for PDA closure in preterm infants. Data from 7 randomized controlled trials (RCTs) showed that all-cause mortality and other clinical adverse outcomes did not differ between expectant management of PDA and active treatment. Future large-scale and double-blinded RCTs with a consistent definition for hemodynamically significant PDA, and focusing on clearly delineated high-risk subgroups or later selective treatment are needed to further evaluate the role of expectant management.

Association of Hospital Procedural Volume With Outcomes of Left Ventricular Assist Device Placement.

BACKGROUND: With the advancement in device technology, the use of durable left ventricular assist devices (LVADs) has increased significantly in recent years. However, there is a dearth of evidence to conclude whether patients who undergo LVAD implantation at high-volume centers have better clinical outcomes than those receiving care at low- or medium-volume centers. METHODS: We analyzed the hospitalizations using the Nationwide Readmission Database for the year 2019 for new LVAD implantation. Baseline comorbidities and hospital characteristics were compared among low- (1-5 procedures/year), medium- (6-16 procedures/year) and high-volume (17-72 procedures/year) hospitals. The volume/outcome relationship was analyzed using the annualized hospital volume as a categorical variable (tertiles) as well as a continuous variable. Multilevel mixed-effect logistic regression and negative binomial regression models were used to determine the association of hospital volume and outcomes, with tertile 1 (low-volume hospitals) as the reference category. RESULTS: A total of 1533 new LVAD procedures were included in the analysis. The inpatient mortality rate was lower in the high-volume centers compared with the low-volume centers (9.04% vs 18.49%, aOR 0.41, CI0.21-0.80; P = 0.009). There was a trend toward lower mortality rates in medium-volume centers compared with low-volume centers; however, it did not reach statistical significance (13.27% vs 18.49%, aOR 0.57, CI0.27-1.23; P = 0.153). Similar results were seen for major adverse events (composite of stroke/transient ischemic attack and in-hospital mortality). There was no significant difference in bleeding/transfusion, acute kidney injury, vascular complications, pericardial effusion/hemopericardium/tamponade, length of stay, cost, or 30-day readmission rates between medium- and high-volume centers compared to low-volume centers. CONCLUSION: Our findings indicate lower inpatient mortality rates in high-volume LVAD implantation centers and a trend toward lower mortality rates in medium-volume LVAD implantation centers compared to lower-volume centers.

Highlights of Cardiovascular Disease Prevention Studies Presented at the 2023 European Society of Cardiology Congress.

PURPOSE OF REVIEW: To summarize selected late-breaking science on cardiovascular (CV) disease prevention presented at the 2023 European Society of Cardiology (ESC) congress. RECENT FINDINGS: The NATURE-PARADOX was a naturally randomized trial that used genetic data from the UK Biobank registry to create "cumulative exposure to low-density lipoprotein-cholesterol (LDL-C)" biomarker and evaluate its association with major CV events regardless of plasma LDL-C levels or age. Safety and efficacy data of inclisiran, a PCSK9-interfering mRNA (PCSK9i) administered subcutaneously twice annually, were presented. Data on two new PCSK9is were presented, recaticimab, an oral drug, and lerodalcibep, a subcutaneous drug with a slightly different architecture than currently available PSCK9is. A phase 1 trial on muvalaplin, an oral lipoprotein (a) inhibitor, was presented. An atherosclerotic CV disease (ASCVD) risk prediction algorithm for the Asian population using SCORE2 data was presented. Long-term follow-up of patients enrolled in the CLEAR outcomes trial showed sustained and more significant ASCVD risk reduction with bempedoic acid in high-risk patients. The late-breaking clinical science at the 2023 congress of the ESC extends the known safety and efficacy data of a PCSK9i with the introduction of new drugs in this class. Using cumulative exposure to LDL-C rather than a single value will help clinicians tailor the LDL-C reduction strategy to individual risk and is an important step towards personalized medicine.

Socioeconomic status and in-hospital outcomes for patients undergoing heart transplantation or ventricular assist device implantation.

INTRODUCTION: Although lower socioeconomic status (SES) has been associated with worse in-hospital outcomes among patients with heart failure, the in-hospital outcomes for patients undergoing durable Left Ventricular Assist Device (LVAD) implantation or Heart Transplantation (HT) based on SES have not been well characterized. METHODS: We analyzed data from the National Inpatient Sample of hospitalizations between January 2016 and December 2020 of patients aged 18 and over who underwent a HT or newly implanted LVAD. Quartile classification of the median household income of the patient's residential zip code was used to estimate SES. Multivariable analyses with logistic and linear regression were used to evaluate the effects of SES on inpatient outcomes including inpatient mortality, length of stay, and key inpatient complications. RESULTS: A total of 16,265 weighted hospitalizations for new LVAD implantation and 14,320 weighted hospitalizations for HT were identified. In multivariable analysis, among patients undergoing HT or LVAD implantation respectively, there were no significant differences between the lowest and highest SES quartiles among important in-hospital outcomes including length of stay (adj B-coeff .56, (-3.59)-(4.71), p = .79 and adj B-coeff 2.40, (-.21)-(5.02), p = .07) and mortality (aOR 1.02, .61-1.70, p = .94 and aOR 1.08, .72-1.62, p = .73). There were also no differences based on SES quartile in important inpatient complications including stroke and cardiac arrest. CONCLUSION: In this analysis from the National Inpatient Sample, we demonstrate that SES, evaluated by median zip code income, was not associated with important in-hospital metrics including mortality and length of stay among patients undergoing LVAD or HT.

Endovascular Transcatheter Aortic Valve Replacement Outcomes in Hypertrophic Cardiomyopathy: Insights from the National Inpatient Sample (2014-2018).

BACKGROUND: Outcomes of patients with hypertrophic cardiomyopathy (HCM) following transcatheter aortic valve replacement (TAVR) remain largely unknown. OBJECTIVES: This study sought to assess the clinical characteristics and outcomes of HCM patients following TAVR. METHODS: We queried the National Inpatient Sample from 2014 to 2018 for TAVR hospitalizations with and without HCM, creating a propensity-matched cohort to compare outcomes. RESULTS: 207,880 patients that underwent TAVR during the study period, 810 (0.38%) had coexisting HCM. In the unmatched population, TAVR patients with HCM compared to those without HCM, were more likely to be female, had a higher prevalence of heart failure, obesity, cancer, and history of pacemaker/implantable cardioverter defibrillation, and were more likely to have nonelective and weekend admissions (p for all <0.05). TAVR patients without HCM had higher prevalence of coronary artery disease, prior percutaneous coronary intervention, prior coronary artery bypass grafting, and peripheral arterial disease compared to their counterparts (p for all <0.05). In the propensity-matched cohort, TAVR patients with HCM had significantly higher incidence of in-hospital mortality, acute kidney injury/hemodialysis, bleeding complications, vascular complications, permanent pacemaker requirement, aortic dissection, cardiogenic shock, and mechanical ventilation requirement. CONCLUSION: Endovascular TAVR in HCM patients is associated with an increased incidence of in-hospital mortality and procedural complications.

Trends in hospitalizations for heart failure, acute myocardial infarction, and stroke in the United States from 2004 to 2018.

AIM: To determine the trends in hospitalizations for heart failure (HF), acute myocardial infarction (AMI), and stroke in the United States (US). METHOD AND RESULTS: A retrospective analysis of the National Inpatient Sample weighted data between January 1, 2004 and December 31, 2018 which included hospitalized adults ≥18 years with a primary discharge diagnosis of HF, AMI, or stroke using International Classification of Diseases-9/10 administrative codes. Main outcomes were hospitalization for HF, AMI, and stroke per 1000 United States adults, length of stay, and in-hospital mortality. There were 33.4 million hospitalizations for HF, AMI, and stroke, with most being for HF (48%). After the initial decline in HF hospitalizations (5.3 hospitalizations/1000 US adults in 2004 to 4 hospitalizations/1000 US adults in 2013, P < .001), there was a progressive increase in HF hospitalizations between 2013 and 2018 (4.0 hospitalizations/1000 US adults in 2013 to 4.9 hospitalizations/1000 US adults in 2018; P < .001). Hospitalization for AMI decreased (3.1 hospitalizations/1000 US adults in 2004 to 2.5 hospitalizations/1000 US adults in 2010, P < .001) and remained stable between 2010 and 2018. There was no significant change for hospitalization for stroke between 2004 and 2011 (2.3 hospitalizations/1000 US adults in 2004 vs 2.3 hospitalizations per 1000 US adults in 2011, P = .614); however, there was a small but significant increase in hospitalization for stroke after 2011 that reached 2.5 hospitalizations/1000 US adults in 2018. Adjusted length of stay and in-hospital mortality decreased for HF, AMI, and stroke hospitalizations. CONCLUSIONS: In contrast to the trend of AMI and stroke hospitalizations, a progressive increase in hospitalizations for HF has occurred since 2013. From 2004 to 2018, in-hospital mortality has decreased for HF, AMI, and stroke hospitalizations.

National trends and disparities in statin use for ischemic heart disease from 2006 to 2018: Insights from National Ambulatory Medical Care Survey.

BACKGROUND: Statins are a cornerstone guideline-directed medical therapy for secondary prevention of ischemic heart disease (IHD). However, recent temporal trends and disparities in statin utilization for IHD have not been well characterized. METHODS: This retrospective analysis included data from outpatient adult visits with IHD from the National Ambulatory Medical Care Survey (NAMCS) between January 2006 and December 2018. We examined the trends and predictors of statin utilization in outpatient adult visits with IHD. RESULTS: Between 2006 and 2018, we identified a total of 542,704,112 weighted adult ambulatory visits with IHD and of those 46.6% were using or prescribed statin. Middle age (50-74 years) (adjusted odds ratio [aOR] 1.65, 95% confidence interval [CI] 1.28-2.13 P < .001) and old age (≥75 years) (aOR = 1.66, CI 1.26-2.19, P < .001) compared to young age (18-49 years), and male sex (aOR = 1.35, CI 1.23-1.48, P < .001) were associated with greater likelihood of statin utilization, whereas visits with non-Hispanic (NH) Black patients (aOR = 0.75, CI 0.61-0.91, P = .005) and Hispanic patients (aOR = 0.74, CI 0.60-0.92, P = .006) were associated with decreased likelihood of statin utilization compared to NH White patient visits. Compared with private insurance, statin utilization was nominally lower in Medicare (aOR = 0.91, CI 0.80-1.02, P = .112), Medicaid (aOR = 0.78, CI 0.59-1.02, P = .072) and self-pay/no charge (aOR = 0.72, CI 0.48-1.09, P = .122) visits, however did not reach statistical significance. There was no significant uptake in statin utilization from 2006 (44.1%) to 2018 (46.2%) (P = .549). CONCLUSIONS: Substantial gaps remain in statin utilization for patients with IHD, with no significant improvement in use between 2006 and 2018. Persistent disparities in statin prescription remain, with the largest treatment gaps among younger patients, women, and racial/ethnic minorities (NH Blacks and Hispanics).

Contemporary Nationwide Heart Transplantation and Left Ventricular Assist Device Outcomes in Patients with Histories of Bariatric Surgery.

Bariatric surgery may play a role in the management of morbidly obese patients with end-stage heart failure through increasing eligibility and improving the outcomes of destination therapies. We conducted a nationally representative, retrospective cohort study of patients with previous bariatric surgery undergoing either heart transplantation or left ventricular assist device implantation. Of 200 patients, < 6% experienced in-hospital mortality after destination therapy, comparable to that reported in the general population of heart recipients. Risk-adjusted outcomes differed minimally from those of obese patients undergoing destination therapy without previous bariatric surgery. This study provides important safety benchmarking data and demonstrates the feasibility of bariatric surgery as a potential bridge to left ventricular assist device implantation or heart transplantation in obese patients with end-stage heart failure.

Trends, predictors, and outcomes of transcatheter aortic valve implantation in patients with bicuspid aortic valve related disease: Insights from the Nationwide Inpatient Sample and Nationwide Readmission Database.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has increasingly been utilized in patients with bicuspid aortic valve (BAV) related aortic stenosis (AS) with insufficient large-scale data on its safety. METHODS: The Nationwide Inpatient Sample and Nationwide Readmission Database (2011-2018) were queried to identify patients undergoing TAVI for BAV versus trileaflet aortic valve (TAV) associated AS. The in-hospital, 30- and 180-day odds of outcomes were assessed using a propensity-matched analysis (PSM) to calculate adjusted odds ratios (aOR) with its 95% confidence interval (CI). RESULTS: A total of 216,723 TAVI (TAV: 214,050 and BAV: 2,673) crude and 5,347 matched population (TAV: 2,674 and BAV: 2,673) was included in the final analysis. At index admission, the adjusted odds of in-hospital mortality (aOR: 1.57, 95% CI: 0.67-3.66), stroke (aOR: 0.77, 95% CI: 0.38-1.57), cardiac tamponade (aOR: 0.75, 95% CI: 0.17-3.36), vascular complications (aOR: 0.33, 95% CI: 0.09-1.22), cardiogenic shock (aOR: 1.77, 95% CI: 0.93-3.38), paravalvular leak (aOR: 0.55, 95% CI: 0.26-1.14), need for mechanical circulatory support device, and permanent pacemaker implantation (PPM) (aOR: 1.02, 95% CI: 0.69-1.52) were not significantly different between TAVI for BAV versus TAV. At 30- and 180-day follow-up duration, the risk of stroke and major postprocedural complications remained similar, except that TAVI in BAV had a higher incidence of PPM implantation compared with TAV. The yearly trend showed an increase in the utilization of TAVI for both TAV and BAV and a steady decline in the overall annual rate of in-hospital complications. CONCLUSION: TAVI utilization in patients with BAV has increased over the recent years. The relative odds of in-hospital mortality, and all other major complications, were similar between patients undergoing TAVI for BAV- and TAV-related AS.

Impact of the heart transplant allocation policy change on inpatient cost of index hospitalization.

BACKGROUND: We sought to determine the financial impact of the United Network for Organ Sharing heart transplant (HT) allocation policy change of October 2018. METHODS: Using the Nationwide Inpatient Sample we retrospectively analyzed hospital discharge data between January 1, 2016 and December 31, 2019. ICD-10-CM procedure codes were used to identify hospitalizations of patients undergoing HT as well as the use of temporary mechanical circulatory support (MCS) during the HT hospitalization. Patients < 18 years old and those with missing data on costs were excluded. The primary outcome was inflation-adjusted costs. Total costs were inflated to 2019 US dollars. RESULTS: During the course of the study, temporary MCS increased significantly among 11 380 weighted patients transplanted while mean length of stay (LOS) did not. Mean inflation-adjusted costs rose about $40k per HT. On univariate analysis, transplantation year, use of temporary MCS and LOS were all significantly associated with increased cost while on multivariate analysis only temporary MCS and LOS were. CONCLUSIONS: The 2018 allocation change has resulted in more expensive inpatient costs for HT correlating with an increase in temporary MCS.

Left atrial appendage closure using WATCHMAN device in chronic kidney disease and end-stage renal disease patients.

BACKGROUND: Chronic kidney disease (CKD) and end-stage renal disease are considered independent risk factors for developing atrial fibrillation (AF). Percutaneous occlusion of left atrial appendage (LAAC) using WATCHMAN device is a widely accepted alternative to anticoagulation therapy to prevent ischemic stroke in AF in patients who are not candidates for anticoagulation. There is limited data regarding the utilization and periprocedural safety of this intervention in patients with CKD/ESRD. METHODS: We retrospectively reviewed all hospitalizations from 2016 to 2017 with (ICD-10) procedure diagnosis code of LAA closure using WATCHMAN procedure with and without a secondary diagnosis of CKD/ESRD in acute-care hospitals across the United States using the national inpatient sample. Demographic variables (gender, race, income, hospital characteristics, medical comorbidities) were collected and compared. The primary outcomes were inpatient mortality, hospital length, and cost of stay. RESULTS: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. Sixteen thousand five hundred five hospitalizations were for adult patients with a procedure code for LAA closure via watchman procedure. Of 16,505 patients, 3245 (19.66%) had CKD and ESRD. There was no statistically significant difference in mortality, length, and cost of stay in patients with and without CKD/ESRD. There were no statistically significant differences in periprocedural cerebrovascular accidents in both groups. CONCLUSION: Patients with and without ESRD/CKD who undergo LAA occlusion with Watchman have similar procedure related, in-hospital mortality, and complications.

Current status of perioperative temporary mechanical circulatory support during cardiac surgery.

OBJECTIVES: We sought to determine utilization and outcomes of perioperative temporary mechanical circulatory support (tMCS) in the current practice of cardiac surgery. BACKGROUND: tMCS is an evolving adjunct to cardiac surgery not fully characterized in contemporary practice. METHODS: Using the nationwide inpatient sample we retrospectively analyzed hospital discharge data between January 1, 2016 and December 31, 2019. ICD-10-CM procedure codes were used to identify and divide patient hospitalizations into those who had preoperative tMCS (pre-tMCS) versus tMCS instituted the day of surgery or afterwards (sd/post-tMCS). RESULTS: In all, 1,383,520 hospitalizations met inclusion criteria. 86,445 (6.25%) had tMCS. tMCS was utilized in 8.74% of coronary artery bypass grafting (CABG), 2.58% of isolated valve, and 9.71% of valve/CABG; operations. 29,325 (33.9%) had pre-tMCS while 57,120 (66.1%) had sd/post-tMCS. The use of tMCS was associated with greater inpatient mortality (15.66% vs. 1.53%, p < .001), longer length of stay (LOS) (14.4 vs. 8.5 days, p < .001), and higher mean inflation-adjusted costs ($93,040 ± 1038 vs. $51,358 ± 296, p < .001) compared to no use. Inpatient mortality (5.98% vs. 20.63%, p < .001), LOS (13.87 vs. 14.68, p < .001), and cost ($82,621 ± 1152 SEM vs. $98,381 ± 1242) were all significantly lower with pre-tMCS compared to sd/post tMCS. When analyzed separately, mortality was higher with later utilization of tMCS (5.98% pre, 17.1% sd, and 49.05% postsurgical date insertion, p < .001). CONCLUSIONS: Perioperative tMCS is utilized in 6.25% of modern cardiac surgery, with two-thirds of cases instituted on the day of surgery or afterwards. The use of tMCS is associated with significantly higher mortality, longer LOS, and higher costs. Among patients undergoing tMCS, earlier utilization is associated with better outcomes.

In-hospital outcomes of transcatheter mitral valve repair in patients with and without end stage renal disease: A national propensity match study.

OBJECTIVES: To study trends of utilization, outcomes, and cost of care in patients undergoing undergoing transcatheter mitral valve repair (TMVr) with end-stage renal disease (ESRD). BACKGROUND: Renal disease has been known to be a predictor of poor outcome in patients with mitral valve disease. Outcome data for patients with ESRD undergoing TMVr remains limited. Therefore, our study aims to investigate trends of utilization, outcomes, and cost of care among patients with ESRD undergoing TMVr. METHODS: We analyzed NIS data from January 2010 to December 2017 using the ICD-9-CM codes ICD-10-CM to identify patients who underwent TMVr. Baseline characteristics were compared using a Pearson 𝜒2 test for categorical variables and independent samples t-test for continuous variables. Propensity matched analysis was done for adjusted analysis to compare outcomes between TMVr with and without ESRD. Markov chain Monte Carlo was used to account for missing values. RESULTS: A total of 15,260 patients (weighted sample) undergoing TMVr were identified between 2010 and 2017. Of these, 638 patients had ESRD compared to 14,631 patients who did not have ESRD. Adjusted in-hospital mortality was lower in non-ESRD group (3.9 vs. <1.8%). Similarly, ESRD patients were more likely to have non-home discharges (85.6 vs. 74.9%). ESRD patients also had a longer mean length of stay (7.9 vs. 13.5 days) and higher mean cost of stay ($306,300 vs. $271,503). CONCLUSION: ESRD is associated with higher mortality, complications, and resource utilization compared to non-ESRD patients. It is important to include this data in shared decision-making process and patient selection.

Brief report: Effect of cardiac multi-morbidity on COVID hospitalization outcomes.

BACKGROUND: The COVID-19 pandemic has stretched healthcare resources thin and led to significant morbidity and mortality. There have been no studies utilizing national data to investigate the role of cardiac risk factors on outcomes of COVID hospitalizations. The aim of this study was to examine the effect of cardiac multimorbidity on healthcare utilization and outcomes among COVID hospitalizations during the first year of the pandemic. METHODS: Using the national inpatient sample (NIS), we identified all adult hospital admissions with a primary diagnosis of COVID in 2020, using International Classification of Diseases, Tenth Revision, Clinical Modification codes (ICD010-CM). Coronary artery disease, diabetes mellitus, heart failure, peripheral vascular disease, previous stroke, and atrial fibrillation were then identified as cardiac comorbidities using ICD-10-CM codes. Multivariable logistic regression was used to evaluate the effect of cardiac multimorbidity on mortality and mechanical ventilation. RESULTS: We identified 1,005,040 primary COVID admissions in 2020. Of these admissions, 216,545 (20.6%) had CAD, 413,195 (39.4%) had DM, 176,780 (16.8%) had HF, 159,700 (15.2%) had AF, 30735 (2.9%) had PVD, and 25,155 (2.4%) had a previous stroke. When stratified by number of comorbidities, 428390 (40.8%) had 0 comorbidities, 354960 (33.8%) had 1, 161225 (15.4%) had 2, and 105465 (10.0%) had 3+ comorbidities. COVID hospitalizations with higher cardiac multimorbidity had higher mortality rates (p<0.001) higher MV rates (p<0.001). In our multivariable regression, these associations remained with increasing odds for mortality with each stepwise increase in cardiac multimorbidity (1: OR 1.48 (1.45-1.50); 2: OR 2.13 (2.09-2.17); 3+: OR 2.43 (2.38-2.48), p<0.001, all). CONCLUSIONS: Our study is the first national examination of the impact of cardiac comorbidities on COVID outcomes. A higher number of cardiac comorbidities was associated with significantly higher rates of MV and in-hospital mortality, independent of age. Future, more granular, and longitudinal studies are needed to further examine these associations.

Social Vulnerability and Cardiovascular-Related Mortality Among Older Adults in the United States.

PURPOSE: The association of social vulnerability and cardiovascular disease-related mortality in older adults has not been well characterized. METHODS: The Centers for Disease Control and Prevention database was evaluated to examine the relationship between county-level Social Vulnerability Index (SVI) and age-adjusted cardiovascular disease-related mortality rates (AAMRs) in adults aged 65 and above in the United States between 2016 and 2020. RESULTS: A total of 3139 counties in the United States were analyzed. Cardiovascular disease-related AAMRs increased in a stepwise manner from first (least vulnerable) to fourth SVI quartiles; (AAMR of 2423, 95% CI [confidence interval] 2417-2428; 2433, 95% CI 2429-2437; 2516, 95% CI 2513-2520; 2660, 95% CI 2657-2664). Similar trends among AAMRs were noted based on sex, all race and ethnicity categories, and among urban and rural regions. Higher AAMR ratios between the highest and lowest SVI quartiles, implying greater relative associations of SVI on mortality rates, were seen among Hispanic individuals (1.52, 95% CI 1.49-1.55), Non-Hispanic-Asian and Pacific Islander individuals (1.32, 95% CI 1.29-1.52), Non-Hispanic- American Indian or Alaskan Native individuals (1.43, 95% CI 1.37-1.50), and rural counties (1.21, 95% CI 1.20-1.21). CONCLUSION: Social vulnerability as measures by the SVI was associated with cardiovascular disease-related mortality in older adults, with the association being particularly prominent in ethnic minority patients and rural counties.
