Prevalence and impact of takotsubo syndrome in hospitalizations for acute ischemic stroke.

Takotsubo syndrome (TTS) is characterized by acute and reversible left ventricular dysfunction with apical ballooning arising during acute stress situations. Acute ischemic stroke (AIS) is one of the known triggers of TTS; however, the impact of TTS on in-hospital outcomes of AIS remains unexplored. We utilized data from the National Inpatient Sample (2007-2014) to identify admissions for AIS with TTS and evaluated the temporal trends, baseline characteristics, in-hospital complications, length of stay, and all-cause mortality. Survey multivariable logistic regression was used to compute adjusted odds ratios (OR) and 95% confidence intervals (CI). An estimated 2242 (0.4%) TTS cases were identified among AIS hospitalizations (N = 4,392,471). The frequency of TTS was higher in elderly, white, and female patients. After adjustment for confounders, TTS incidence in AIS was associated with higher odds of in-hospital complications including cardiogenic shock (OR 8.84, CI 4.07-19.17, P < 0.001), cardiac arrest (OR 3.17, CI 1.57-6.42, P = 0.001), and venous thromboembolism (OR 1.68, CI 1.14-2.47, P = 0.008). Moreover, AIS hospitalizations with TTS showed higher odds of developing respiratory failure (OR 3.13, CI 2.42-4.05, P < 0.001) and requiring mechanical ventilation/intubation (OR 4.09, CI 3.14-5.32, P < 0.001) compared to the non-TTS cohort. The AIS-TTS cohort had a longer length of stay (8.59 vs 5.22 days), and their mortality rate was twice (10.2% vs 5.1%; P < 0.001) that of those without TTS. In conclusion, the prevalence of TTS in AIS remained ∼20 times higher than in the general inpatient population and predisposed AIS patients to worse inpatient outcomes. Further studies are needed to evaluate the impact of TTS on long-term outcomes in AIS.

Trends and outcomes of chronic coronary total occlusion-related ventricular tachyarrhythmias.

Our study aims to establish trends and frequencies of ventricular tachyarrhythmia (VTA) among patients with chronic coronary total occlusion (CCTO). We identified CCTO hospitalizations with and without VTA using the National Inpatient Sample. A total of 911,579 CCTO-related hospitalizations were identified, with 92,450 (10.1%) encounters associated with VTA. The CCTO-VTA cohort showed higher all-cause mortality (adjusted odds ratio [aOR] = 4.45, P < 0.001), longer hospital stays (6.8 vs 4.6 days; P < 0.001), and higher hospital charges ($117,382 vs $75,419; P < 0.001) compared to the CCTO non-VTA group. Rates and odds of cardiogenic shock (aOR = 4.19), venous thromboembolism (aOR = 2.09), respiratory failure (aOR = 2.85), and requirement of mechanical ventilation (aOR = 4.23) were higher in the CCTO-VTA group (P < 0.001). Over time, there was an increase in VTA (9.2% in 2010 to 12.1% in 2014) and all-cause mortality (7.5% in 2010 to 12.4% in 2014; P < 0.001). Trends in VTA among patients with CCTO increased by 4.8% for undergoing percutaneous coronary intervention and by 2.5% for undergoing both percutaneous coronary intervention and coronary artery bypass grafting (P < 0.001). Occurrence of VTA among CCTO patients is associated with worse outcomes and higher resource utilization.

Burden of arrhythmias and associated in-hospital mortality in acute decompensated diabetes mellitus.

To gain understanding of the burden of cardiac arrhythmias in patients with acutely decompensated diabetes mellitus (ADDM) on a large scale, we reviewed data on ADDM patients and subtypes of arrhythmias from the National Inpatient Sample from 2010 to 2014. The frequency and prevalence of cardiac arrhythmias were measured, as well as outcomes. Among 874,107 hospitalized ADDM patients identified, 87,970 (10.1%) developed arrhythmias. The ADDM-arrhythmia cohort showed higher all-cause mortality (1.4% vs 0.3%; adjusted odds ratio 2.58, 95% confidence interval 2.39-2.79, P < 0.001), prolonged hospital stays (4.2 ± 4.8 vs 3.3 ± 3.4 days), and higher hospital charges ($32,609 vs $23,741) compared to those without arrhythmias (P < 0.001). The prevalence of supraventricular arrhythmia (atrial fibrillation, supraventricular tachycardia, and atrial flutter) and ventricular arrhythmia (ventricular tachycardia and ventricular fibrillation) was 2965 and 446 per 100,000 ADDM-related hospitalizations, respectively. The prevalence of any arrhythmias and atrial fibrillation in ADDM patients increased by 20.4% and 38.1%, respectively. The highest increase in the prevalence of arrhythmia among ADDM patients was observed in adults aged 18 to 44 years (22.5%).

Sickle cell disease-associated arrhythmias and in-hospital outcomes: Insights from the National Inpatient Sample.

BACKGROUND: The frequency and temporal trend in the prevalence of arrhythmias and associated in-hospital outcomes in patients with sickle cell disease (SCD) have never been quantified. METHODS: Our study cohort of SCD patients and sub-types of arrhythmias were derived from the 2010-2014 National Inpatient Sample using relevant diagnostic codes. The frequency and trends of arrhythmia and odds of inpatient mortality were measured. RESULTS: A total of 891 450 hospitalized SCD patients were identified, of which, 55 616 (6.2%) patients experienced arrhythmias. The SCD cohort with arrhythmia demonstrated higher all-cause mortality (2.7% vs 0.4%; adjusted OR 2.53, 95% CI 2.15-2.97, P < .001), prolonged hospital stays (6.9 vs 5.0 days) and higher hospital charges ($53 871 vs $30 905) relative to those without arrhythmias (P < .001).The frequency of supraventricular arrhythmia (AFib, SVT, and AF) and ventricular arrhythmia (VFib and VT) were 1893 and 362 per 100 000 SCD-related admissions, respectively. Unspecified arrhythmias (4126) were seen most frequently followed by AFib (1622) per 100 000 SCD-related admissions. From 2010 to 2014, the frequency of any arrhythmias and atrial fibrillation in hospitalized SCD patients relatively increased by 29.6% and 38.5%, respectively. There was nearly a twofold (2.4% in 2010 to 5.0% in 2014) increase in the frequency of arrhythmia among patients aged <18 years. The frequency of arrhythmias in hospitalized male and female SCD patients relatively increased by 28.8% and 31.4%, respectively (P trend < .001). CONCLUSIONS: The frequency of arrhythmias among SCD patients is on the rise with worse hospitalization outcomes, including higher in-hospital mortality and higher resource utilization as compared to those without arrhythmias.

Nationwide Trends in Prevalent Cardiovascular Risk Factors and Diseases in Young Adults: Differences by Sex and Race and In-Hospital Outcomes.

OBJECTIVES: Prevalence and trends in all cardiovascular disease (CVD) risk factors among young adults (18-39 years) have not been evaluated on a large scale stratified by sex and race. The aim of this study was to establish the prevalence and temporal trend of CVD risk factors in US inpatients younger than 40 years of age from 2007 through 2014 with racial and sex-based distinctions. In addition, the impact of these risk factors on inpatient outcomes and healthcare resource utilization was explored. METHODS: A cross-sectional nationwide analysis of all hospitalizations, comorbidities, and complications among young adults from 2007 to 2014 was performed. The primary outcomes were frequency, trends, and race- and sex-based differences in coexisting CVD risk factors. Coprimary outcomes were trends in all-cause mortality, acute myocardial infarction, arrhythmia, stroke, and venous thromboembolism in young adults with CVD risk factors. Secondary outcomes were demographics and resource utilization in young adults with versus without CVD risk factors. RESULTS: Of 63 million hospitalizations (mean 30.5 [standard deviation 5.9] years), 27% had at least one coexisting CVD risk factor. From 2007 to 2014, admission frequency with CVD risk factors increased from 42.8% to 55.1% in males and from 16.2% to 24.6% in females. Admissions with CVD risk were higher in male (41.4% vs 15.9%) and white (58.4% vs 53.8%) or African American (22.6% vs 15.9%) patients compared with those without CVD risk. Young adults in the Midwest (23.9% vs 21.1%) and South (40.8% vs 37.9%) documented comparatively higher hospitalizations rates with CVD risk. Young adults with CVD risk had higher all-cause in-hospital mortality (0.4% vs. 0.3%) with a higher average length of stay (4.3 vs 3.2 days) and charges per admission ($30,074 vs $20,124). CONCLUSIONS: Despite modern advances in screening, management, and interventional measures for CVD, rising trends in CVD risk factors across all sex and race/ethnic groups call for attention by preventive cardiologists.

National prevalence, trends and outcomes of takotsubo syndrome in hospitalizations with prior history of mediastinal/intrathoracic cancer and radiation therapy.

BACKGROUND: Radiation therapy (RT) for cancers in thoracic/mediastinal region has been linked with heart damage following years of radiation exposure. However, prevalence of takotsubo syndrome (TTS) in patients with prior intrathoracic/mediastinal malignancies treated with RT has never been analyzed on a large scale. METHODS: We identified adult hospitalizations with prior mediastinal/intrathoracic cancer and RT and TTS using ICD-9 CM codes and the National Inpatient Sample (2007-2014) after excluding current admissions for chemotherapy. We then assessed the prevalence, odds, trends and in-hospital outcomes of TTS-related admissions in patients with vs. without prior intrathoracic cancer and RT. RESULTS: We identified a total of 5,991,314 hospitalizations with prior intrathoracic/mediastinal malignancies and RT (~73 yrs., 85.2% female), of which 7663 (0.13%, 128 per 100,000) were diagnosed with TTS (~74 yrs., 95.8% females, 88.1% white). Higher odds and rising trends in TTS per 100,000 hospitalizations (from 31 to 241) were seen among patients with prior intrathoracic malignancies and RT as compared to those without (from 19 to 104) (ptrend < 0.001). All-cause in-hospital mortality (4.6% vs 2.8%; OR 1.45; 95%CI 1.29-1.63, p < 0.001), cardiogenic shock (4.3% vs 0.2%), cardiac arrest (3.1% vs 0.9%), arrhythmia (34.3% vs 24.6%), stroke (3.6% vs 2.8%), respiratory failure (14.5% vs 4.6%), and median length of stay and hospital charges were significantly higher in the TTS cohort. CONCLUSIONS: This study showed higher odds and increasing trends in TTS-related admissions with worse in-hospital outcomes among patients with prior intrathoracic/mediastinal cancer and RT, irrespective of the time interval from cancer diagnosis or RT to TTS occurrence.

Frequency of takotsubo cardiomyopathy in epilepsy-related hospitalizations among adults and its impact on in-hospital outcomes: A national standpoint.

BACKGROUND: Literature remains constrained to case reports with respect to epilepsy-associated takotsubo cardiomyopathy (TC) or stress-induced cardiomyopathy and its impact on in-hospital outcomes remains largely obscure. METHODS: The National Inpatient Sample databases (2010-2014) were queried to identify and compare baseline characteristics and outcomes in adult hospitalizations for epilepsy with and without secondary TC using ICD-9-CM codes and propensity-matching. Primary outcomes were the frequency of TC, ensuing all-cause mortality, and complications. Secondary outcome was healthcare resource utilization. RESULTS: Of 981,571 epilepsy-related hospitalizations, 854 (0.1%, 1 in 1000) admissions (unspecified, 49.1%; grand mal/status epilepticus, 28.1% and generalized convulsive 11.7%) revealed associated in-hospital TC. Of the propensity-matched cohorts of epilepsy (TC = 793; mean 61.1 ±â€¯15.0 yrs. & 82.4% females vs. non-TC = 795; mean 60.7 ±â€¯14.2 yrs. & 84.2% females), the TC group consisted more often white (83.7% vs. 78.0%, p < 0.02) patients with higher cardiovascular risk factors. The all-cause inpatient mortality (3.7% vs <11; p = 0.002), arrhythmia (22.7% vs. 18.7%, p = 0.05), cardiac arrest (3.9% vs <11; p = 0.001), cardiogenic shock (3.2% vs <11, p < 0.001), stroke (3.5% vs 1.9%, p = 0.04), venous thromboembolism (4.4% vs. 1.9%, p = 0.004), and respiratory failure (29.4% vs. 14.8%, p < 0.001) were significantly higher in the TC cohort. The mean LOS (6.3 ±â€¯5.6 vs. 5.1 ±â€¯7.1 days), hospital charges ($77,908 vs. $45,881), transfers to other facilities (3.8% vs. 3.2%), and need of home healthcare (19.4% vs. 9.9%) were higher in the TC group (p < 0.001). CONCLUSION: In this nationwide population-based study, 1 in every 1000 epilepsy-related hospitalizations was associated with secondary TC which resulted in poor inpatient outcomes and higher healthcare resource utilization.

Regional trends in In-hospital Cardiac Arrest following sepsis-related admissions and subsequent mortality.

BACKGROUND: Previous studies have reported regional variation in either the incidence or outcomes of sepsis or In-hospital Cardiac Arrest (IHCA) discretely; however, regional variations in the incidence and outcomes of sepsis-associated IHCA (SA-IHCA) have never been studied. METHODS: From the National Inpatient Sample (NIS), discharges with sepsis and sepsis-associated IHCA were identified in 4 geographic regions (Northeast, Midwest, South, West) from 2007 to 2014 using applicable ICD-9-CM codes. We assessed the regional incidence and trends in SA-IHCA and subsequent inpatient outcomes. RESULTS: Out of 8,058,091 sepsis-related admissions, 187,163 (2.3%) were associated with IHCA with a rising trend in the incidence from 2007- to 2014 (2.0% to 2.6%, ptrend < 0.001). The overall incidence of SA-IHCA was highest in South (2.6%) with the highest mortality in West (74.4%) (p < 0.001). The incidence of SA-IHCA increased in the South (2.4%-3.0%) and Midwest (1.6%-2.4%) from 2007 to 2014. Mortality has not significantly increased or decreased across all regions. Compared with the West, survivors in the Northeast, Midwest, and the South were less likely to be discharged home and were more likely to be transferred to other facilities. In the SA-IHCA cohort, the mean length of stay for SA-IHCA was highest in Northeast (˜10.9 days) and lowest in Midwest (˜8.6 days) (p < 0.001). Hospital charges were highest in the West ($234,278) and lowest in the Midwest ($125,725) (p < 0.001). CONCLUSION: This nationwide analysis demonstrates that the highest incidence of SA-IHCA is in the Southern region of the US whereas the associated in-hospital mortality was highest in the West. The incidence of SA-IHCA is rising in the Midwest and South from 2007 to 2014. Despite significant advances in the treatment of sepsis and IHCA, there has been no significant improvement in the incidence of SA-IHCA and subsequent survival in any US geographic region from 2007 to 2014.

In-hospital outcomes of inflammatory bowel disease in cannabis users: a nationwide propensity-matched analysis in the United States.

BACKGROUND: Literature suggests the role of cannabis (marijuana) as an anti-inflammatory agent. However, the impact of recreational marijuana usage on in-hospital outcomes of inflammatory bowel disease (IBD) remains indistinct. We assessed the outcomes of Crohn's disease (CD) as well as ulcerative colitis (UC) with vs. without recreational marijuana usage using a nationally illustrative propensity-matched sample. METHODS: The Nationwide Inpatient Sample datasets (2010-2014) were queried to identify adults with CD and UC hospitalizations with cannabis use and linked complications using ICD-9 CM codes. Categorical and continuous variables were compared between propensity-matched cohorts using Chi-square and Student's t-test, respectively. Primary endpoints were in-hospital complications, whereas secondary endpoints were the discharge disposition, mean length of stay (LOS) and hospital charges. RESULTS: Propensity-matched cohorts included 6,002 CD (2,999 cannabis users & 3,003 non-users) and 1,481 UC (742 cannabis users & 739 non-users) hospitalizations. In CD patients, prevalence of colorectal cancer (0.3% vs. 1.2%, P<0.001), need for parenteral nutrition (3.0% vs. 4.7%, P=0.001) and anemia (25.6% vs. 30.1%, P<0.001) were lower in cannabis users. However, active fistulizing disease or intraabdominal abscess formation (8.6% vs. 5.9%, P<0.001), unspecific lower gastrointestinal (GI) hemorrhage (4.0% vs. 2.7%, P=0.004) and hypovolemia (1.2% vs. 0.5%, P=0.004) were higher with recreational cannabis use. The mean hospital stay was shorter (4.2 vs. 5.0 days) with less hospital charges ($28,956 vs. $35,180, P<0.001) in cannabis users. In patients with UC, cannabis users faced the higher frequency of fluid and electrolyte disorders (45.1% vs. 29.6%, P<0.001), and hypovolemia (2.7% vs. <11) with relatively lower frequency of postoperative infections (<11 vs. 3.4%, P=0.010). No other complications were significant enough for comparison between the cannabis users and non-users in this group. Like CD, UC-cannabis patients had shorter mean hospital stay (LOS) (4.3 vs. 5.7 days, P<0.001) and faced less financial burden ($30,393 vs. $41,308, P<0.001). CONCLUSIONS: We found a lower frequency of colorectal cancer, parenteral nutrition, anemia but a higher occurrences of active fistulizing disease or intraabdominal abscess formation, lower GI hemorrhage and hypovolemia in the CD cohort with cannabis usage. In patients with UC, frequency of complications could not be compared between the two cohorts, except a higher frequency of fluid and electrolyte disorders and hypovolemia, and a lower frequency of postoperative infections with cannabis use. A shorter LOS and lesser hospital charges were observed in both groups with recreational marijuana usage.

Epidemiology of acute coronary syndrome co-existent with allergic/hypersensitivity/anaphylactic reactions (Kounis syndrome) in the United States: A nationwide inpatient analysis.

BACKGROUND: The nationwide epidemiological data on Kounis Syndrome (KS), still remains indistinct in the United States (US) after it was first reported in 1991. METHODS: We assessed the prevalence of KS among patients primarily hospitalized for allergic/hypersensitivity/anaphylactic reactions. We then compared baseline demographics, comorbidities, and outcomes of KS with patients with only allergic/hypersensitivity/anaphylactic reactions using the National Inpatient Sample, 2007-2014. RESULTS: The cohort comprised of 235,420 patients primarily hospitalized with allergy/hypersensitivity/anaphylactic reactions. Of these, 2616 [1.1%; 0.2% unstable angina, 0.2% ST-elevation myocardial infarction & 0.7% non-ST-elevation myocardial infarction] patients experienced ACS and were identified as having KS. Patients with KS were older (mean 65.9 ±â€¯14.1 vs. 57.2 ±â€¯17.8 yrs), more often White (71.1% vs. 58.6%), male (46.4% vs. 39.9%) and Medicare enrollees (58.9% vs. 41.5%) admitted non-electively (96.8% vs. 95.3%) as compared to non-KS group (p < 0.001). The hospitalizations with KS demonstrated higher all-cause in-hospital mortality (7.0% vs. 0.4%, p < 0.001), prolonged hospitalization stay (mean 5.8 ±â€¯6.0 vs. 3.0 ±â€¯3.9 days, p < 0.001), higher hospitalization charges ($52,656 vs. $20,487, p < 0.001) and more frequent transfers to other facilities. The rates of stroke (1.0% vs. 0.2%), arrhythmias (30.4% vs. 12.4%), venous thromboembolism (1.6% vs. 1.0%), and diagnostic and therapeutic coronary interventions were also found to be significantly higher in patients with KS (p < 0.05). Patients with KS had increased odds of in-hospital mortality [unadjusted OR: 18.52; 95% CI: 15.74-21.80, p < 0.001 & adjusted OR: 9.74, 95% CI: 8.08-11.76, p < 0.001] compared to non-KS group. CONCLUSIONS: Overall US prevalence of KS among patients hospitalized for allergic/hypersensitivity/anaphylactic reactions is 1.1% with a subsequent all-cause inpatient mortality rate of 7.0%.

A Nationwide Assessment of the "July Effect" and Predictors of Post-Endoscopic Retrograde Cholangiopancreatography Sepsis at Urban Teaching Hospitals in the United States.

BACKGROUND/AIMS: To analyze the incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) sepsis in the early (July to September) and later (October to June) academic months to assess the "July effect". METHODS: The National Inpatient Sample (2010-2014) was used to identify ERCP-related adult hospitalizations at urban teaching hospitals by applying relevant procedure codes from the International Classification of Diseases, 9th revision, Clinical Modification. Post-ERCP outcomes were compared between the early and later academic months. A multivariate analysis was performed to evaluate the odds of post-ERCP sepsis and its predictors. RESULTS: Of 481,193 ERCP procedures carried out at urban teaching hospitals, 124,934 were performed during the early academic months. The demographics were comparable for ERCP procedures performed during the early and later academic months. A higher incidence (9.4% vs. 8.8%, p<0.001) and odds (odds ratio [OR], 1.07) of post-ERCP sepsis were observed in ERCP performed during the early academic months. The in-hospital mortality rate (7% vs. 7.5%, p=0.072), length of stay, and total hospital charges in patients with post-ERCP sepsis were also equivalent between the 2 time points. Pre-ERCP cholangitis (OR, 3.20) and post-ERCP complications such as cholangitis (OR, 6.27), perforation (OR, 3.93), and hemorrhage (OR, 1.42) were significant predictors of higher post-ERCP sepsis in procedures performed during the early academic months. CONCLUSION: The July effect was present in the incidence of post-ERCP sepsis, and academic programs should take into consideration the predictors of post-ERCP sepsis to lower health-care burden.

Predictors of blood transfusion and in-hospital outcomes in patients with gastric antral vascular ectasia (GAVE): a nationwide population-based analysis.

BACKGROUND: Gastric antral vascular ectasia (GAVE) is a rare cause of chronic non-variceal upper gastrointestinal (GI) bleeding and can turn into life-threatening bleed in some patients. Packed red blood cell (PRBC) transfusions are often required in these patients during hospitalization. We aimed to investigate the hospitalization outcomes and predictors of PRBC transfusions in patients with GAVE lesions. METHODS: Using the ICD-9-CM codes (537.82, 537.83), we queried the National Inpatient Sample (NIS) [2010-2014] to recognize hospitalized GAVE patients. A 1:2 random sample was obtained from the non-GAVE cohort and these groups were compared (GAVE vs. non-GAVE). The predictors of PRBC transfusion in GAVE cohort were analyzed with multivariate analysis by using SPSS Statistics 22.0. RESULTS: We included weighted 89,081 GAVE and 178,550 non-GAVE hospitalized patients. The GAVE patients were tended to be older, female and white. Significantly higher proportions of comorbidities such as congestive heart failure, diabetes, hypertension, hypothyroidism, liver disease, renal failure, Sjogren syndrome, systemic sclerosis and portal hypertension, etc. were present in these patients. The all-cause inpatient mortality was found to be 1.4%. The mean hospital charges and length of stay (LOS) per GAVE hospitalization were $36,059 and 4.63±5.3 days, respectively. A total of 6,276 (weighted 31,102) (34.9%) of these patients received at least one PRBC transfusion during hospitalization. Advanced age, multiple comorbidities, non-elective admissions, male gender, and African American race were the independent factors associated with higher chances of receiving PRBC transfusion. CONCLUSIONS: Our analysis showed that hospitalized patients with GAVE lesions had lower overall mortality rate despite having multiple comorbidities. There was no difference in the LOS and hospital charges between the two cohorts. Nearly 35% of the GAVE patients received at least one PRBC transfusion.

The burden and impact of arrhythmia in chronic obstructive pulmonary disease: Insights from the National Inpatient Sample.

BACKGROUND: We aimed to analyze the burden and predictors of arrhythmias and in-hospital mortality in chronic obstructive pulmonary disease (COPD)-related hospitalizations using the nationwide cohort. METHODS: We queried the National Inpatient Sample (NIS) (2010-2014) databases to identify adult COPD hospitalizations with arrhythmia. Categorical and continuous variables were compared using Chi-square and Student's t-test/ANOVA. Predictors of any arrhythmia including AF and in-hospital mortality were evaluated by multivariable analyses. RESULTS: Out of 21,596,342 COPD hospitalizations, 6,480,799 (30%) revealed co-existent arrhythmias including 4,767,401 AF-arrhythmias (22.1%) and 1,713,398 non AF-arrhythmias (7.9%). The AF or non-AF arrhythmia cohort consisted mostly of older (mean age~ 75.8 & 69.1 vs. 67.5 years) white male (53.3% & 51.9% vs. 46.9%) patients compared to those without arrhythmias (p < 0.001). The all-cause mortality (5.7% & 5.2 vs. 2.9%), mean length of stay (LOS) (6.4 & 6.5 vs. 5.3 days), and hospital charges ($52,699.49 & $58,102.39 vs. $41,208.02) were higher with AF and non AF-arrhythmia compared to the non-arrhythmia group (p < 0.001). Comorbidities such as cardiomyopathy (OR 2.11), cardiogenic shock (OR 1.88), valvular diseases (OR 1.60), congestive heart failure (OR 1.48) and pulmonary circulation disorders (OR 1.25) predicted in-hospital arrhythmias. Invasive mechanical ventilation (OR 6.41), cardiogenic shock (OR 5.95), cerebrovascular disease (OR 3.95), septicemia (OR 2.30) and acute myocardial infarction (OR 2.24) predicted higher mortality (p < 0.001) in the COPD-arrhythmia cohort. CONCLUSIONS: About 30% of COPD hospitalizations revealed co-existent arrhythmias (AF 22.1%). All-cause mortality, LOS and hospital charges were significantly higher with arrhythmias. We observed racial and sex-based disparities for arrhythmias and related mortality.

Modern-Day Nationwide Utilization of Intravascular Ultrasound and Its Impact on the Outcomes of Percutaneous Coronary Intervention With Coronary Atherectomy in the United States.

OBJECTIVES: Intravascular ultrasonography (IVUS) and coronary atherectomy (CA) are useful modalities in managing calcified coronary lesions. Considering an inadequacy of data, we aimed to compare the outcomes with versus without IVUS assistance in percutaneous coronary interventions (PCIs) with CA. METHODS: From the National (Nationwide) Inpatient Sample data set for the years 2012 to 2014, we identified adult patients undergoing PCI and CA with or without IVUS assistance using International Classification of Diseases, Ninth Revision, Clinical Modification codes. We assessed the impact of IVUS on procedural outcomes, length of stay, total hospital charges, and predictors of IVUS utilization by multivariable analyses. Discharge weights were used to calculate national estimates. RESULTS: A total of 46,095 PCIs with CA procedures were performed from 2012 to 2014, of these, 4800 (10.4%) procedures were IVUS-assisted. IVUS-assisted procedures showed lower odds of in-hospital mortality (odds ratio, 0.57; P = .024) but higher odds of any cardiac complication (odds ratio, 1.25; P = .025). Total hospital charges were higher in IVUS-assisted procedures without any substantial difference in the length of stay between the groups. Cardiac complication rates declined (from 16.2% to 14.8%) from 2012 to 2014, whereas inpatient mortality increased (1.1%-4.4%) in IVUS-assisted procedures during the same period. The odds of IVUS utilization were higher in Asian/Pacific Islander and urban teaching and western region hospitals. Comorbidities, including hypertension, obesity, and chronic pulmonary disease, raised odds of IVUS utilization. CONCLUSIONS: IVUS-assisted procedures showed lower in-hospital mortality and higher iatrogenic and overall cardiac complications. The mortality rate in patients undergoing IVUS-assisted PCI with CA was on the rise, with declining cardiac complication rates from 2012 to 2014.

Alarming Increasing Trends in Hospitalizations and Mortality With Heyde's Syndrome: A Nationwide Inpatient Perspective (2007 to 2014).

We studied the trends and outcomes of patients with intestinal angiodysplasia-associated gastrointestinal bleeding (Heyde's syndrome [HS]) with aortic stenosis (AS) who underwent surgical aortic valve replacement (SAVR) versus transcatheter aortic valve implantation (TAVI). The National Inpatient Sample (2007 to 2014) and International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify HS hospitalizations, pertinent co-morbidities, and outcomes of SAVR versus TAVI from 2011 to 2014. The incidence of HS with AS was 3.1%. The trends in hospitalizations and all-cause inpatient mortality showed relative surges of 29.16% (from 48 to 62 per 100,000) and 22.7% (from 3.7 to 4.54 per 100,000) from 2007 to 2014. HS patients were older (mean age ∼80 vs 77 years) females (54.3% vs 52.2%) compared with AS without HS. The all-cause mortality (6.9% vs 4.1%), length of stay (LOS) (∼7.0 vs 5.8 days), and hospitalization charges ($58,519.31 vs $57,598.67) were higher in HS (p<0.001). No differences were reported in all-cause mortality and hospital charges in HS patients who underwent either SAVR or TAVI. However, the TAVI cohort showed lower rates of stroke (1.7% vs 10.0%) and blood transfusion (1.7% vs 11.7%), a shorter LOS (18.3 vs 23.9 days; p<0.001), and more routine discharges (21.7% vs 14.8%, p = 0.01). An older age, male gender, Asian race, congestive heart failure, coagulopathy, fluid and/or electrolytes disorders, chronic pulmonary disease, and renal failure raised the odds of mortality in HS patients. In conclusion, we observed increasing rates of hospitalizations with HS and higher inpatient mortality from 2007 to 2014. The HS patients who underwent TAVI had fewer complications without any difference in the all-cause mortality compared with SAVR.

Thirty-Day Readmissions After Upper and Lower Gastrointestinal Hemorrhage: A National Perspective in the United States.

BACKGROUND: Upper gastrointestinal hemorrhage (UGIH) and lower gastrointestinal hemorrhage (LGIH) are 2 of the most common reasons for hospital admissions across the United States. The 30-day readmission after index admission poses a major burden on the health care infrastructure, and thus, it is important to assess the causes of 30-day readmission for patients with UGIH and LGIH. METHODS: The study cohort was derived from the 2013 National Readmission Database. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) Volume 3 diagnosis codes were utilized to identify UGIH and LGIH patients from this data set. Patients who were readmitted to the hospital within 30 days within the same calendar year were further analyzed. Categorical variables and continuous variables were assessed by the χ test and the student t test, respectively. The independent predictors of unplanned 30-day readmissions were recognized by multivariate logistic regression, adjusting for stratified cluster design of National Readmission Database. SAS 9.4 (SAS Institute Inc., Cary, NC) was used for data analysis. RESULTS: The number of index admissions identified from the National Readmission Data 2013 were 82,290 for UGIH and 133,114 for LGIH. All-cause 30-day readmission rate for UGIH versus LGIH was 14.6% (readmitted N=12,046; 56.64% age 65 y and above) versus 14.4% (readmitted N=19,128; 70.21% age 65 y and above and 49.61% men). Gastrointestinal causes were most common (33.9% vs. 39.6%), followed by cardiac (13.3% vs. 15.3%), infectious (10.4% vs. 9.1%), and respiratory causes (7.8% vs. 7.1%) for 30-day readmission for UGIH and LGIH. Significant predictors of increased 30-day readmission (odds ratio, 95% confidence interval, P-value) included metastatic disease (2.15, 1.75-2.64, P<0.001), discharge against medical advice (1.85, 1.55-2.22, P<0.001), and length of stay >3 days (1.50, 1.38-1.63, P<0.001). Predictors for 30-day readmission for LGIH included metastatic disease (1.75, 1.48-2.06, P<0.001), liver disease (1.59, 1.49-1.71, P<0.001), and drug abuse (1.38, 1.21-1.58, P<0.001). CONCLUSIONS: Most common reason for UGIH and LGIH readmission was related to gastrointestinal disease, followed by cardiac, infectious, and respiratory etiologies. By addressing these etiologies for readmission, it may be possible to reduce adverse outcomes.
