#SoMe for #IC: Optimal use of social media in interventional cardiology.

Social media allows interventional cardiologists to disseminate and discuss research and clinical cases in real-time, to demonstrate and learn innovative techniques, to build professional networks, and to reach out to patients and the general public. Social media provides a democratic platform for all participants to influence the conversation and demonstrate their expertise. This review addresses the use of social media for these purposes in interventional cardiology, as well as respect for patient privacy, how to get started on social media, the creation of high-impact social media content, and the role of traditional journals in the age of social media. In the future, we hope that interventional cardiology fellowship programs will incorporate social media training into their curricula. In addition, professional societies may adapt to the rapid dissemination of data on social media by developing processes to update guidelines more rapidly and more frequently.

COVID-19 and the cardiovascular system: A review of current data, summary of best practices, outline of controversies, and illustrative case reports.

As the severe acute respiratory syndrome coronavirus 2 virus pandemic continues to grow globally, an association is apparent between patients with underlying cardiovascular disease comorbidities and the risk of developing severe COVID-19. Furthermore, there are potential cardiac manifestations of severe acute respiratory syndrome coronavirus 2 including myocyte injury, ventricular dysfunction, coagulopathy, and electrophysiologic abnormalities. Balancing management of the infection and treatment of underlying cardiovascular disease requires further study. Addressing the increasing reports of health care worker exposure and deaths remains paramount. This review summarizes the most contemporary literature on the relationship of the cardiovascular system and COVID-19 and society statements with relevance to protection of health care workers, and provides illustrative case reports in this context.

The influence of Elixhauser comorbidity index on percutaneous coronary intervention outcomes.

BACKGROUND: Clinical outcomes with respect to the evolution of comorbidity burden in national cohorts of patients undergoing PCI have not been reported. OBJECTIVES: We sought to explore the association between comorbidity burden and periprocedural outcomes in patients treated with PCI in the National Inpatient Sample. METHODS: 6,601,526 PCI procedures were identified between 2004 and 2014 and comorbidities were defined by the Elixhauser classification system (ECS) consisting of 30 comorbidity measures. Endpoints included in-hospital mortality, periprocedural complications, length of stay and cost. Patients were classified based on their ECS in five categories (ECS I < 0, ECS II = 0, ECS III = 1-5, ECS IV = 6-13, and ECS V ≥ 14). RESULTS: Patients with a score over 13 had a fivefold increase in the odds of mortality (OR: 5.13, 95% CI: 4.76-5.54), major bleeding (OR: 11.46, 95% CI: 10.66-12.33) and doubled the hospitalization costs ($31,452 vs $17.566). CONCLUSIONS: Our study of over six million PCI procedures demonstrates that patients with the greatest comorbid burden (as defined by an ECS of >13) have a fivefold increase risk of in-hospital mortality, a fourfold increase in in-hospital periprocedural complications and an 11-fold increase in major bleeding events once differences in baseline patient characteristics are adjusted for. In addition, ECS significantly impacts the length of stay and doubles the healthcare costs. Comorbid burden is an important predictor of poor outcomes after PCI and should be considered as part of the decision-making processes in patients undergoing PCI.

Incidence and predictors of acute coronary syndrome after transcatheter mitral valve repair.

BACKGROUND: Acute coronary syndrome (ACS) post-transcatheter mitral valve repair (TMVR) carries high mortality. We aim to study the incidence and predictors of ACS in patients who underwent TMVR. RESEARCH DESIGN AND METHODS: We queried the U.S. National Readmission Database to identify all cases of TMVR from 2016 to 2019. We further evaluated the incidence of ACS and used multivariable logistic regression to determine independent predictors of ACS in this population. RESULTS: Among 3,742 patients who underwent TMVR, 264 (7.05%) developed ACS. Among ACS patients, 204 (77%) had non-ST-segment elevation ACS and 66 (25%) had ST-segment elevation ACS. Independent predictors of ACS were acute limb ischemia, cardiogenic shock, history of coronary artery disease (CAD), smoking, cardiac arrest, respiratory failure requiring mechanical ventilation, and acute kidney injury. In-hospital mortality among ACS was three times higher in ACS patients than without ACS (16.76% vs. 5.45%, p-value < 0.01). CONCLUSIONS: ACS is not an uncommon complication after TMVR. The occurrence of ACS after TMVR is associated with high in-hospital mortality, longer length of stay, and higher hospital charges. The strongest predictors of ACS in these patients are the development of acute limb ischemia, cardiogenic shock, and a history of CAD.

A meta-analysis of left ventricular dysfunction in ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic inflammatory arthritis affecting the spine, presenting a considerable morbidity risk. Although evidence consistently indicates an elevated risk of ischemic heart disease among AS patients, debates persist regarding the likelihood of these patients developing left ventricular dysfunction (LVD). Our investigation aimed to determine whether individuals with AS face a greater risk of LVD compared to the general population. To accomplish this, we identified studies exploring LVD in AS patients across five major databases and Google Scholar. Initially, 431 studies were identified, of which 30 met the inclusion criteria, collectively involving 2933 participants. Results show that AS patients had: (1) poorer Ejection Fraction (EF) [mean difference (MD): -0.92% (95% CI: -1.25 to -0.59)], (2) impaired Early (E) and Late (atrial-A) ventricular filling velocity (E/A) ratio [MD: -0.10 m/s (95% CI: -0.13 to -0.08)], (3) prolonged deceleration time (DT) [MD: 12.30 ms (95% CI: 9.23-15.36)] and, (4) a longer mean isovolumetric relaxation time (IVRT) [MD: 8.14 ms (95% CI: 6.58-9.70)] compared to controls. Though AS patients show increased risks of both systolic and diastolic LVD, we found no significant differences were observed in systolic blood pressure [MD: 0.32 mmHg (95% Confidence Interval (CI): -2.09 to 2.73)] or diastolic blood pressure [MD: 0.30 mmHg (95% CI: -0.40 to 1.01)] compared to the general population. This study reinforces AS patients' susceptibility to LVD without a notable difference in HTN risk.

Thirty-day hospital readmission in females with acute heart failure and breast cancer: A retrospective cohort study from national readmission database.

BACKGROUND: Breast Cancer and cardiovascular diseases are amongst the two leading causes of mortality in the United States, and the two conditions are connected in part because of recognized cardiotoxicity of cancer treatments. The aim of this study is to investigate the predictors risk factors for thirty-day readmission in female breast cancer survivors presenting with acute heart failure. METHODS: This is a retrospective cohort study of acute heart failure (AHF) hospitalization in female patients with breast cancer in 2019 using the National Readmission Database (NRD), which is the largest publicly available all-payer inpatient readmission database in the United States. Our study sample included adult female patients aged 18 years and older. The primary outcome of interest was the rate of 30- day readmission. RESULTS: In 2019, there were 8332 total index admissions for AHF in females with breast cancer and 7776 patients were discharged alive. The mean age was 74.4 years (95% CI: 74, 74.7). The percentage of readmission at 30 days among those discharged alive was 21.8% (n = 1699). Hypertensive heart disease with chronic kidney disease accounted for the majority of readmission in AHF with breast cancer followed by sepsis, acute kidney injury, respiratory failure, pneumonia, and atrial fibrillation. Demographic factors including higher burden of comorbidities predict readmission. The total in-hospital mortality in index admission was 6.67% (n = 556) and for readmitted patients was 8.77% (n = 149). The mean length of stay for index admission was 7.5 days (95% CI: 7.25, 7.75). CONCLUSIONS: Readmission of female breast cancer survivors presenting with AHF is common and largely be attributed to high burden of comorbidities including hypertension, and chronic kidney disease. A focus on close outpatient follow-up will be beneficial in lowering readmissions.

Effects of Valvular Heart Disease on Clinical Outcomes in Sarcoidosis.

Systemic sarcoidosis can lead to heart failure, conduction abnormalities and ventricular arrhythmias although data on concomitant valvular heart disease (VHD) is limited. We reported the prevalence and outcomes of VHD in systemic sarcoidosis. A retrospective cohort study was conducted using National Inpatient Sample between 2016 and 2020 with respective ICD-10-CM codes. 406,315 patients were hospitalized with sarcoidosis, out of which 20,570 had comorbid VHD (5.1%). Mitral disease was most common (2.5%), followed by aortic, and tricuspid disease. Tricuspid disease was associated with increased mortality in sarcoidosis (OR 1.6, 95% CI, 1.1-2.6, P = 0.04), while aortic disease was associated with higher mortality in only 31-50 years age cohort. Patients with sarcoidosis and VHD have higher hospitalization charges and lower or similar valvular intervention rates than those without sarcoidosis. VHD has a prevalence of 5% in sarcoidosis, predominantly affecting mitral and aortic valves. Underlying VHD is associated with worse outcomes in sarcoidosis.

Prediabetes is an incremental risk factor for adverse cardiac events: A nationwide analysis.

Background and aims: Prediabetes is defined as a state of impaired glucose metabolism with hemoglobin A1c (HbA1c) levels that precede those of a diabetic state. There is increasing evidence that suggests that hyperglycemic derangement in prediabetes leads to microvascular and macrovascular complications even before progression to overt diabetes mellitus. We aim to identify the association of prediabetes with acute cardiovascular events. Methods: We utilized the National inpatient sample 2018-2020 to identify adult hospitalizations with prediabetes after excluding all hospitalizations with diabetes. Demographics and prevalence of other cardiovascular risk factors were compared in hospitalizations with and without prediabetes using the chi-square test for categorical variables and the t-test for continuous variables. Multivariate regression analysis was further performed to study the impact of prediabetes on acute coronary syndrome, acute ischemic stroke, intracranial hemorrhage, and acute heart failure. Results: Hospitalizations with prediabetes had a higher prevalence of cardiovascular risk factors like hypertension, hyperlipidemia, obesity, and tobacco abuse. In addition, the adjusted analysis revealed that hospitalizations with prediabetes were associated with higher odds of developing acute coronary syndrome (OR-2.01; C.I:1.94-2.08; P<0.001), acute ischemic stroke (OR-2.21; 2.11-2.31; p<0.001), and acute heart failure (OR-1.41; C.I.: 1.29-1.55; p<0.001) as compared to hospitalizations without prediabetes. Conclusions: Our study suggests that prediabetes is associated with a higher odds of major cardiovascular events. Further prospective studies should be conducted to identify prediabetes as an independent causative factor for these events. In addition, screening and lifestyle modifications for prediabetics should be encouraged to improve patient outcomes.

Mechanical Circulatory Support in Patients With COVID-19 Presenting With Myocardial Infarction.

ST-segment elevation myocardial infarction (STEMI) complicating COVID-19 is associated with an increased risk of cardiogenic shock and mortality. However, little is known about the frequency of use and clinical impact of mechanical circulatory support (MCS) in these patients. We sought to define patterns of MCS utilization, patient characteristics, and outcomes in patients with COVID-19 with STEMI. The NACMI (North American COVID-19 Myocardial Infarction) is an ongoing prospective, observational registry of patients with COVID-19 positive (COVID-19+) with STEMI with a contemporary control group of persons under investigation who subsequently tested negative for COVID-19 (COVID-19-). We compared the baseline characteristics and in-hospital outcomes of COVID-19+ and patients with COVID-19- according to the use of MCS. The primary outcome was a composite of in-hospital mortality, stroke, recurrent MI, and repeat unplanned revascularization. A total of 1,379 patients (586 COVID-19+ and 793 COVID-19-) enrolled in the NACMI registry between January 2020 and November 2021 were included in this analysis; overall, MCS use was 12.3% (12.1% [n = 71] COVID-19+/MCS positive [MCS+] vs 12.4% [n = 98] COVID-19-/MCS+). Baseline characteristics were similar between the 2 groups. The use of percutaneous coronary intervention was similar between the groups (84% vs 78%; p = 0.404). Intra-aortic balloon pump was the most frequently used MCS device in both groups (53% in COVID-19+/MCS+ and 75% in COVID-19-/MCS+). The primary outcome was significantly higher in COVID-19+/MCS+ patients (60% vs 30%; p = 0.001) because of very high in-hospital mortality (59% vs 28%; p = 0.001). In conclusion, patients with COVID-19+ with STEMI requiring MCS have very high in-hospital mortality, likely related to the significantly higher pulmonary involvement compared with patients with COVID-19- with STEMI requiring MCS.

Management and outcomes of acute myocardial infarction in patients with preexisting heart failure: an analysis of 2 million patients from the national inpatient sample.

BACKGROUND: Inpatient management and outcomes of patients presenting with acute myocardial infarction (AMI) with a history of heart failure (HF) have not been well characterized. METHODS: Hospitalizations for AMI from the Nationwide Inpatient Sample (2015-2018) were categorized according to a preexisting diagnosis of HF with preserved ejection fraction (HFpEF), reduced ejection fraction (HFrEF), or absence of HF. Utilization of invasive management and in-hospital outcomes were analyzed. RESULTS: Among 2,434,639 hospitalizations with an AMI, 19.8% had a history of HFrEF and 11.9% had a history of HFpEF. Coronary angiography and PCI respectively were performed significantly less among patients with HF (36.6% and 17.4% in HFpEF, 51.1% and 24.6% in HFrEF, and 64.4% and 42.3% among patients without HF, all p < 0.0001). Mortality was more common among patients with HFrEF (10.3%) and HFpEF (8.3%) when compared to patients without a history of HF (6.4%), p < 0.0001. CONCLUSION: HF is a common preexisting comorbidity among patients presenting with AMI and is associated with lower utilization of invasive procedures and higher complications including mortality, particularly among those with HFrEF.

Meta-Analysis Comparing Distal Radial Versus Traditional Radial Percutaneous Coronary Intervention or Angiography.

Data comparing outcomes of distal radial (DR) and traditional radial (TR) access of coronary angiography and percutaneous coronary intervention (PCI) are limited. Online databases including Medline and Cochrane Central databases were explored to identify studies that compared DR and TR access for PCI. The primary outcome was the rate of radial artery occlusion (RAO) and access failure. Secondary outcomes included access site hematoma, access site bleeding, access site pain, radial artery spasm, radial artery dissection, and crossover. Unadjusted odds ratios (ORs) with a random-effect model, 95% confidence interval (CI), and p <0.05 were used for statistical significance. Metaregression was performed for 16 studies with 9,973 (DR 4,750 and TR 5,523) patients were included. Compared with TR, DR was associated with lower risk of RAO (OR 0.51, 95% CI 0.29 to 0.90, I2 = 42.6%, p = 0.02). RAO was lower in DR undergoing coronary angiography rather than PCI. Access failure rate (OR 1.77, 95% CI 0.69 to 4.55, I2 87.36%, p = 0.24), access site hematoma (OR 1.11, 95% CI 0.68 to 1.83, I2 0%, p = 0.68), access site pain (OR 2.22, 95% CI 0.28 to 17.38, I2 0%, p = 0.45), access site bleeding (OR 1.11, 95% CI 0.16 to 7.62, I2 85.11%, p = 0.91), radial artery spasm (OR 0.79, 95% CI 0.49 to 1.29, I2 0%, p = 0.35), radial artery dissection (OR 1.63, 95% CI 0.46 to 5.84, I2 0%, p = 0.45), and crossover (OR 1.54, 95% CI 0.64 to 3.70, I2 25.48%, p = 0.33) did not show any significant difference. DR was associated with lower incidence RAO when compared with TR, whereas other procedural-related complications were similar.

Trends and Outcomes of Ischemic Stroke after Transcatheter Aortic Valve Implantation, A US National Propensity Matched Analysis.

Contemporary data on stroke predictors and outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) remains limited. We analyzed National Inpatient Sample data from the year 2011 to 2018. A total of 215,938 patients underwent TAVI. Of the patients who underwent TAVI, 4579 (2.2%) suffered from stroke and 211359 (97.8%) did not have a stroke. Adjusted mortality was higher in patients who had a stroke (10.9%) as compared to patients who did not have a stroke (3.1%). Lower percentage of patients were discharged home who developed a stroke compared to patients without a stroke (10.2% vs 52.3%). Multivariate logistic regression analysis showed that at baseline, age, female sex, atrial fibrillation, chronic kidney disease and peripheral vascular disease were significant predictors of stroke. Median Cost of care ($63367 vs $48070) and length of stay (8 vs 4 days) were considerably higher for patients with stroke when compared to the comparison group (P < 0.01 for all). In conclusion we report that stroke is associated with increased mortality, morbidity, and resource utilization in patients undergoing TAVI. Baseline characteristics like age, gender, atrial fibrillation, chronic kidney disease and peripheral vascular disease are significant predictors of this adverse event.

Comorbidity burden in patients undergoing left atrial appendage closure.

OBJECTIVE: To estimate the risk of in-hospital complications after left atrial appendage closure (LAAC) in relationship with comorbidity burden. METHODS: Cohort-based observational study using the US National Inpatient Sample database, 1 October 2015 to 31 December 2017. The main outcome of interest was the occurrence of in-hospital major adverse events (MAE) defined as the composite of bleeding complications, acute kidney injury, vascular complications, cardiac complications and postprocedural stroke. Comorbidity burden and thromboembolic risk were assessed by the Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Score (ECS) and CHA2DS2-VASc score. MAE were identified using International Classification of Diseases, Tenth Revision, Clinical Modification codes. The associations of comorbidity with in-hospital MAE were evaluated using logistic regression models. RESULTS: A total of 3294 hospitalisations were identified, among these, the mean age was 75.7±8.2 years, 60% were male and 86% whites. The mean CHA2DS2-VASc score was 4.3±1.5 and 29.5% of the patients had previous stroke or transient ischaemic attack. The mean CCI and ECS were 2.2±1.9 and 9.7±5.8, respectively. The overall composite rate of in-hospital MAE after LAAC was 4.6%. Females and non-whites had about 1.5 higher odds of in-hospital AEs as well participants with higher CCI (adjusted OR (aOR): 1.19, 95% CI: 1.13 to 1.24, p<0.001), ECS (aOR: 1.06, 95% CI: 1.05 to 1.08, p<0.001) and CHA2DS2-VASc score (aOR: 1.08, 95% CI: 1.02 to 1.15, p=0.01) were significantly associated with in-hospital MAE. CONCLUSION: In this large cohort of LAAC patients, the majority of them had significant comorbidity burden. In-hospital MAE occurred in 4.6% and female patients, non-whites and those with higher burden of comorbidities were at higher risk of in-hospital MAE after LAAC.

Racial, ethnic and socioeconomic disparities in patients undergoing left atrial appendage closure.

OBJECTIVE: This manuscript aims to explore the impact of race/ethnicity and socioeconomic status on in-hospital complication rates after left atrial appendage closure (LAAC). METHODS: The US National Inpatient Sample was used to identify hospitalisations for LAAC between 1 October 2015 to 31 December 2018. These patients were stratified by race/ethnicity and quartiles of median neighbourhood income. The primary outcome was the occurrence of in-hospital major adverse events, defined as a composite of postprocedural bleeding, cardiac and vascular complications, acute kidney injury and ischaemic stroke. RESULTS: Of 6478 unweighted hospitalisations for LAAC, 58% were male and patients of black, Hispanic and 'other' race/ethnicity each comprised approximately 5% of the cohort. Adjusted by the older Americans population, the estimated number of LAAC procedures was 69.2/100 000 for white individuals, as compared with 29.5/100 000 for blacks, 47.2/100 000 for Hispanics and 40.7/100 000 for individuals of 'other' race/ethnicity. Black patients were ~5 years younger but had a higher comorbidity burden. The primary outcome occurred in 5% of patients and differed significantly between racial/ethnic groups (p<0.001) but not across neighbourhood income quartiles (p=0.88). After multilevel modelling, the overall rate of in-hospital major adverse events was higher in black patients as compared with whites (OR: 1.60, 95% CI 1.22 to 2.10, p<0.001); however, the incidence of acute kidney injury was higher in Hispanics (OR: 2.19, 95% CI 1.52 to 3.17, p<0.001). No significant differences were found in adjusted overall in-hospital complication rates between income quartiles. CONCLUSION: In this study assessing racial/ethnic disparities in patients undergoing LAAC, minorities are under-represented, specifically patients of black race/ethnicity. Compared with whites, black patients had higher comorbidity burden and higher rates of in-hospital complications. Lower socioeconomic status was not associated with complication rates.

How the COVID-19 Pandemic Has Affected Cardiology Fellow Training.

With the advent of the COVID-19 pandemic in the United States, resources have been reallocated and elective cases have been deferred to minimize the spread of the disease, altering the workflow of cardiac catheterization laboratories across the country. This has in turn affected the training experience of cardiology fellows, including diminished procedure numbers and a narrow breadth of cases as they approach the end of their training before joining independent practice. It has also taken a toll on the emotional well-being of fellows as they see their colleagues, loved ones, patients or even themselves struggling with COVID-19, with some succumbing to it. The aim of this opinion piece is to focus attention on the impact of the COVID-19 pandemic on fellows and their training, challenges faced as they transition to practicing in the real world in the near future and share the lessons learned thus far. We believe that this is an important contribution and would be of interest not only to cardiology fellows-in-training and cardiologists but also trainees in other procedural specialties.

Effect of Location on Treatment and Outcomes of Cardiac Arrest Complicating Acute Myocardial Infarction in England & Wales.

We investigated the incidence, management, and outcomes of acute myocardial infarction (AMI) patients according to cardiac arrest location. Patients admitted with a diagnosis of AMI between January 1, 2010 to March 31, 2017 from the Myocardial Ischaemia National Audit Project (MINAP) were studied. We used logistic regression models to evaluate predictors of the clinical outcomes and treatment strategy. The study population consisted of 580,796 patients admitted with AMI stratified into three groups: out of hospital cardiac arrest (OOHCA) (16,278[2.8%]), in-hospital cardiac arrest (IHCA) (21,073[3.7%]), plus a reference group consisting of those without cardiac arrest (non-cardiac arrest (543,418[93.5%]). IHCA declined steadily (from 666 per 1000 in 2010 to 477 per 1000 AMI with cardiac arrest admissions in 2017) with a commensurate rise in OOHCA (from 344 per 1000 to 533 per 1000 AMI with cardiac arrest admissions). Coronary angiography utilization (OOHCA 81.1% vs IHCA 60.3% vs non-cardiac arrest 70.4%, p < 0.001) and PCI (OOHCA 40% vs IHCA 32.8% vs non-cardiac arrest 45.2%, p < 0.001) were higher in OOHCA. In-hospital mortality odds were greatest for IHCA (OR 35.3, 95% CI 33.4-37.2) compared to OOHCA (OR 12.7, 95% CI 11.9-13.6), with the worse outcomes seen in patients on medical wards (OR 97.37, 95% CI 87.02-108.95) and the best outcomes seen in the emergency department (OR 8.35, 95% CI 7.32-9.53). In conclusion, outcomes of AMI complicated by cardiac arrest depended on cardiac arrest location, especially the outcomes of the IHCA.

Bioresorbable polymer and durable polymer metallic stents in coronary artery disease: a meta-analysis.

BACKGROUND: Literature on bioresorbable-polymer-stents (BPS) and second-generation durable-polymer-stents (DPS) in percutaneous coronary intervention (PCI) for all comer CAD is conflicting. METHODS: Randomized controlled studies comparing PCI among BPS and second-generation DPS were identified up until May-2020 from online databases.  Primary outcomes included are all-cause myocardial infarction (MI), cardiac-death, target-vessel-revascularization (TVR), target-vessel MI (TVMI), and stent-thrombosis (ST). Random effect method of risk ratio and confidence interval of 95% was used. RESULTS: 25 prospective randomized controlled trials with 31,822 patients (BPS n = 17,065 and DPS n = 14,757) were included in the study. Follow-up ranged between a minimum of 6 months to more than 5 years. Cardiac death (RR 1.02, 95% CI 0.89-1.45, p = 0.16) was comparable in BPS and second-generation DPS. Risk of all-cause MI was similar between BPS and DPS (RR 0.97, 95% CI 0.84-1.11, p = 0.73). TVMI (RR 0.88, 95% CI 0.69-1.11, p = 0.33) and ST rates were also comparable in BPS and DPS groups (RR 1.06, 95% CI 0.80-1.40, p = 1.00). Overall TVR had comparable outcomes between BPS and DPS (RR 0.95, 95% CI 0.79-1.14, p < 0.001); however, higher TVR was seen among BPS group at follow-up of ≥5 years (RR 1.39, 95% CI 1.12-1.14, p = 0.02). Bias was low and heterogeneity was moderate. CONCLUSION: Patients undergoing PCI treated with BPS had comparable outcomes in terms of cardiac death, TVR, ST, TVMI, and all-cause MI to patients treated with second-generation DPS; however, BPS had higher rates of TVR for follow-up of ≥5-years.

Acute Myocardial Infarction in Autoimmune Rheumatologic Disease: A Nationwide Analysis of Clinical Outcomes and Predictors of Management Strategy.

OBJECTIVES: To examine national-level differences in management strategies and outcomes in patients with autoimmune rheumatic disease (AIRD) with acute myocardial infarction (AMI) from 2004 through 2014. METHODS: All AMI hospitalizations were analyzed from the National Inpatient Sample, stratified according to AIRD diagnosis into 4 groups: no AIRD, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSC). The associations between AIRD subtypes and (1) receipt of coronary angiography and percutaneous coronary intervention (PCI) and (2) clinical outcomes were examined compared with patients without AIRD. RESULTS: Of 6,747,797 AMI hospitalizations, 109,983 patients (1.6%) had an AIRD diagnosis (RA: 1.3%, SLE: 0.3%, and SSC: 0.1%). The prevalence of RA rose from 1.0% (2004) to 1.5% (2014), and SLE and SSC remained stable. Patients with SLE were less likely to receive invasive management (odds ratio [OR] [95% CI]: coronary angiography-0.87; 0.84 to 0.91; PCI-0.93; 0.90 to 0.96), whereas no statistically significant differences were found in the RA and SSC groups. Subsequently, the ORs (95% CIs) of mortality (1.15; 1.07 to 1.23) and bleeding (1.24; 1.16 to 1.31) were increased in patients with SLE; SSC was associated with increased ORs (95% CIs) of major adverse cardiovascular and cerebrovascular events (1.52; 1.38 to 1.68) and mortality (1.81; 1.62 to 2.02) but not bleeding or stroke; the RA group was at no increased risk for any complication. CONCLUSION: In a nationwide cohort of AMI hospitalizations we found lower use of invasive management in patients with SLE and worse outcomes after AMI in patients with SLE and SSC compared with those without AIRD.

The Predictive Value of CHA2DS2-VASc Score on In-Hospital Death and Adverse Periprocedural Events Among Patients With the Acute Coronary Syndrome and Atrial Fibrillation Who Undergo Percutaneous Coronary Intervention: A 10-Year National Inpatient Sample (NIS) Analysis.

BACKGROUND: The predictive value of CHA2DS2-VASc score regarding the in-hospital death and periprocedural adverse events following percutaneous coronary intervention (PCI) among patients with acute coronary syndrome (ACS) and concomitant atrial fibrillation (AF) is not established. METHODS: We retrospectively analyzed data of patients with the in-hospital and primary diagnosis of ACS, with concomitant AF, who underwent PCI during the 2004-2014 period from the US National Inpatient Sample database. A CHA2DS2-VASc score was incorporated into multiple covariate-adjusted logistic regression analyses to determine its independent impact on designated outcomes. RESULTS: A total of 283,890 patients hospitalized with the primary diagnosis of ACS who underwent PCI and had an AF on record were included in the analysis. The average reported prevalence of AF in the whole cohort of ACS patients was 10.0% with a significant increasing trend during the observed 10-year period (p < .001). The average age of the cohort was 72.1 ±â€¯11 years, 63.4% were male while the median CHA2DS2-VASc score was 3 (IQR 2-4). Following adjustment for baseline covariates, incremental increase in CHA2DS2-VASc score was independently associated with an increased odds of in-hospital death (OR 1.20, CI 95% 1.18-1.22), periprocedural vascular injury (OR 1.18, 95% CI 1.17-1.20), bleeding (OR 1.17, 95% CI 1.16-1.18), stroke/transient ischemic attack (OR 1.17, 95% CI 1.15-1.19), and acute kidney injury (OR 1.05, 95% CI 1.04-1.06). CONCLUSIONS: The CHA2DS2-VASc score provides important prognostic information in ACS patients undergoing PCI. It is independently associated with in-hospital death and adverse periprocedural events following PCI in patients presenting with ACS and concomitant AF.

Cardiac arrest and related mortality in emergency departments in the United States: Analysis of the nationwide emergency department sample.

AIMS: The aim of this study is to analyse the causes of cardiac arrests (CA) in the emergency departments (ED) in the United States and their clinical outcomes according to whether they had a primary or a secondary diagnosis of CA. METHODS: Data from the Nationwide Emergency Department Sample was assessed for episodes of CA in the emergency department (ED) for adults from 2006 to 2014. Primary and secondary diagnoses of CA and mortality outcomes were evaluated in ED, inpatient and the combined in-hospital setting. RESULTS: There were 2,852,347 ED episodes with a diagnosis of CA (50.5% primary diagnosis, 49.5% secondary diagnosis). Among patients with a secondary diagnosis of CA, ∼33% patients had a primary cardiac diagnosis, followed by infectious and respiratory diagnoses. The survival to ED discharge was 53.2%; lower for primary versus secondary CA diagnosis (20.4% vs 86.7%). The in-hospital survival rate for all CA was 28.7%, and was lower for primary versus secondary CA diagnosis (15.7% vs 41.9%). Survival to hospital discharge was highest in the age group of 41-60 years (33.0%) and was least among >80 years (20.9%). Survival was also noted to be lower among female patients (27.9% vs 29.2%) and in the winter months. CONCLUSIONS: Survival with CA in ED is <30% of patients and is greater among patients with a secondary diagnosis of CA. CAs are associated with significant mortality in ED and hospital settings and measures should be taken to better manage cardiac, infection and respiratory causes particularly in the winter months.
