Impact of Advanced Therapy Centers on Characteristics and Outcomes of Heart Failure Admissions. Circ Heart Fail 2024; 17:e011115. [PMID: 38456308 DOI: 10.1161/circheartfailure.123.011115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 01/08/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND Although much attention has been paid to admission and transfer patterns for cardiogenic shock, contemporary data are lacking on decompensated heart failure (HF) admissions and transfers and the impact of advanced therapy centers (ATCs) on outcomes. METHODS HF hospitalizations were obtained from the Nationwide Readmissions Database 2016 to 2019. Centers performing at least 1 heart transplant or left ventricular assist device were classified as ATCs. Patient characteristics, outcomes, and procedural volume were compared among 3 cohorts: admissions to non-ATCs, admissions to ATCs, and transfers to ATCs. A secondary analysis evaluated outcomes for severe HF hospitalizations (cardiogenic shock, cardiac arrest, and mechanical ventilation). Multivariable logistic regression was performed to adjust for the presence of HF decompensations and significant clinical variables during univariate analysis. RESULTS A total of 2 331 690 hospitalizations (81.2%) were admissions to non-ATCs (94.5% of centers), 525 037 (18.3%) were admissions to ATCs (5.5% of centers), and 15 541 (0.5%) were transferred to ATCs. Patients treated at ATCs (especially those transferred) had higher rates of HF decompensations, procedural frequency, lengths of stay, and costs. Unadjusted mortality was 2.6% at non-ATCs and was higher at ATCs, both for directly admitted (2.9%, P<0.001) and transferred (11.2%, P<0.001) patients. However, multivariable-adjusted mortality was significantly lower at ATCs, both for directly admitted (odds ratio, 0.82 [95% CI, 0.78-0.87]; P<0.001) and transferred (odds ratio, 0.66 [95% CI, 0.57-0.78]; P<0.001) patients. For severe HF admissions, unadjusted mortality was 37.2% at non-ATCs and was lower at ATCs, both for directly admitted (25.3%, P<0.001) and transferred (25.2%, P<0.001) patients, with similarly lower multivariable-adjusted mortality. CONCLUSIONS Patients with HF treated at ATCs were sicker but associated with higher procedural volume and lower adjusted mortality.

Impella Versus Intra-Aortic Balloon Pump in Patients With Cardiogenic Shock Treated With Venoarterial Extracorporeal Membrane Oxygenation: An Observational Study. J Am Heart Assoc 2024; 13:e032607. [PMID: 38240236 PMCID: PMC11056174 DOI: 10.1161/jaha.123.032607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 12/19/2023] [Indexed: 02/07/2024]
Abstract
BACKGROUND Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used for patients with cardiogenic shock. Although Impella or intra-aortic balloon pump (IABP) is frequently used for left ventricular unloading (LVU) during VA-ECMO treatment, there are limited data on comparative outcomes. We compared outcomes of Impella and IABP for LVU during VA-ECMO. METHODS AND RESULTS Using the Nationwide Readmissions Database between 2016 and 2020, we analyzed outcomes in 3 groups of patients with cardiogenic shock requiring VA-ECMO based on LVU strategies: extracorporeal membrane oxygenation (ECMO) only, ECMO with IABP, and ECMO with Impella. Of 15 980 patients on VA-ECMO, IABP and Impella were used in 19.4% and 16.4%, respectively. The proportion of patients receiving Impella significantly increased from 2016 to 2020 (6.5% versus 25.8%; P-trend<0.001). In-hospital mortality was higher with ECMO with Impella (54.8%) compared with ECMO only (50.4%) and ECMO with IABP (48.4%). After adjustment, ECMO with IABP versus ECMO only was associated with lower in-hospital mortality (adjusted odds ratio [aOR], 0.83; P=0.02). ECMO with Impella versus ECMO only had similar in-hospital mortality (aOR, 1.09; P=0.695) but was associated with more bleeding (aOR, 1.21; P=0.007) and more acute kidney injury requiring hemodialysis (aOR, 1.42; P<0.001). ECMO with Impella versus ECMO with IABP was associated with greater risk of acute kidney injury requiring hemodialysis (aOR, 1.49; P=0.002), higher in-hospital mortality (aOR, 1.32; P=0.001), and higher 40-day mortality (hazard ratio, 1.25; P<0.001). CONCLUSIONS In patients with cardiogenic shock on VA-ECMO, LVU with Impella, particularly with 2.5/CP, was not associated with improved survival at 40 days but was associated with increased adverse events compared with IABP. More data are needed to assess Impella platform-specific comparative outcomes of LVU.

Trends in the Incidence of Cardiogenic Shock, and Utilization of Mechanical Circulatory Support in Myocarditis: Insights from the National Inpatient Sample 2016 to 2019. Am J Cardiol 2023; 205:406-412. [PMID: 37659261 DOI: 10.1016/j.amjcard.2023.07.183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 07/20/2023] [Accepted: 07/30/2023] [Indexed: 09/04/2023]
Abstract
A subset of patients with myocarditis present with cardiogenic shock. There is a lack of contemporary data assessing the use of mechanical circulatory support (MCS) in these patients. Myocarditis hospitalizations were analyzed using the National Inpatient Sample between 2016 and 2019. Characteristics of patients with and without cardiogenic shock were assessed. Trends in mortality, MCS, right-sided cardiac catheterization (RHC) and endomyocardial biopsy were evaluated. The impact of RHC on consequent MCS and mortality was studied. A total of 38,300 hospitalizations for myocarditis were included in the study, of which 3,490 hospitalizations (9.1%) had cardiogenic shock. Patients with cardiogenic shock were older (p <0.001) and had more chronic kidney disease and atrial fibrillation. Between 2016 and 2019, there was an increase in myocarditis admissions but no difference in rates of cardiogenic shock and mortality and the use of extracorporeal membrane oxygenation, percutaneous ventricular assist devices, intra-aortic balloon pumps, left ventricular assist devices, and cardiac transplant. The most common form of MCS used in myocarditis was extracorporeal membrane oxygenation. The rates of RHC (p = 0.02) and endomyocardial biopsy (p = 0.03) increased over time. Patients who underwent RHC were more likely to receive mechanical support, and in patients with shock, RHC was associated with lower mortality (adjusted odds ratio 0.34, p <0.01). Myocarditis admissions increased over time but with no increase in the rates of cardiogenic shock and MCS. In patients with cardiogenic shock, RHC resulted in lower mortality.

Abstract
Background: New mild or persistent moderate paravalvular leak (PVL) is a known predictor of poor outcomes after transcatheter aortic valve replacement (TAVR). Its impact on left ventricular (LV) remodeling and global longitudinal strain (GLS) has not been well studied. Materials & methods: We collected echocardiographic data in 99 TAVR patients. LV remodeling and GLS were compared between patients with and without PVL. Results: Patients without PVL (n = 84) had significant LV ejection fraction, wall thickness and LV mass improvement compared with patients with PVL (n = 15; p < 0.001 for all). Diastolic function worsened in patients with PVL. Baseline GLS improved significantly regardless of PVL (p = 0.016 and p = 0.01, respectively) and was not predictive of LV ejection fraction or LV mass improvement when analyzed in tertiles. Conclusion: PVL impedes reverse LV remodeling but not GLS improvement 1-year after TAVR. Baseline GLS was not a predictor of LV remodeling.

Abstract
Background We sought to examine patient characteristics, peri‐infarction invasive and pharmacologic management, and in‐hospital major bleeding in myocardial infarction patients with atrial fibrillation or flutter, based on home anticoagulant use. Methods and Results We stratified patients by home anticoagulant: (1) no anticoagulant, (2) warfarin, and (3) direct oral anticoagulants (DOACs) among ST‐segment–elevation myocardial infarction (STEMI) and non‐STEMI (NSTEMI) patients with atrial fibrillation or flutter treated at 761 US hospitals in the ACTION (Acute Coronary Treatment and Intervention Outcomes Network) Registry from January 2015 to December 2016. The primary outcome of our study was in‐hospital major bleeding. Multivariable logistic regression was used to examine the independent association between home anticoagulant and in‐hospital major bleeding. Among 6471 STEMI patients with atrial fibrillation or flutter, 15.7% were on warfarin and 13.0% on DOACs; among 19 954 NSTEMI patients, 22.8% were on warfarin and 15.4% on DOACs. In STEMI, door‐to‐balloon times were slightly higher in those on anticoagulant, with similar rates of angiography within 24 hours in the 3 groups. NSTEMI patients on anticoagulant were less likely to undergo angiography (49.3% no anticoagulant, 33.4% on warfarin, 36.4% on DOACs; P<0.01) or percutaneous coronary intervention within 24 hours (21.1% no anticoagulant, 14.3% on warfarin, 15.9% on DOACs; P<0.01). After multivariate adjustment, use of home warfarin (odds ratio: 1.00 [95% CI, 0.79–1.27] in STEMI and 1.13 [95% CI, 0.97–1.30] in NSTEMI) or DOAC (odds ratio: 0.93 [95% CI, 0.73–1.20] in STEMI and 0.97 [95% CI, 0.81–1.16] in NSTEMI) was not associated with increased in‐hospital major bleeding compared with no anticoagulant. Conclusions In routine clinical practice, home warfarin or DOAC therapy is not associated with an increased risk of in‐hospital bleeding compared with no anticoagulant.

Abstract
Background The ability to accurately predict the occurrence of in‐hospital death after percutaneous coronary intervention is important for clinical decision‐making. We sought to utilize the New York Percutaneous Coronary Intervention Reporting System in order to elucidate the determinants of in‐hospital mortality in patients undergoing percutaneous coronary intervention across New York State. Methods and Results We examined 479 804 patients undergoing percutaneous coronary intervention between 2004 and 2012, utilizing traditional and advanced machine learning algorithms to determine the most significant predictors of in‐hospital mortality. The entire data were randomly split into a training (80%) and a testing set (20%). Tuned hyperparameters were used to generate a trained model while the performance of the model was independently evaluated on the testing set after plotting a receiver‐operator characteristic curve and using the output measure of the area under the curve (AUC) and the associated 95% CIs. Mean age was 65.2±11.9 years and 68.5% were women. There were 2549 in‐hospital deaths within the patient population. A boosted ensemble algorithm (AdaBoost) had optimal discrimination with AUC of 0.927 (95% CI 0.923–0.929) compared with AUC of 0.913 for XGBoost (95% CI 0.906–0.919, P=0.02), AUC of 0.892 for Random Forest (95% CI 0.889–0.896, P<0.01), and AUC of 0.908 for logistic regression (95% CI 0.907–0.910, P<0.01). The 2 most significant predictors were age and ejection fraction. Conclusions A big data approach that utilizes advanced machine learning algorithms identifies new associations among risk factors and provides high accuracy for the prediction of in‐hospital mortality in patients undergoing percutaneous coronary intervention.

Abstract
Background Readmission after ST-segment-elevation myocardial infarction (STEMI) poses an enormous economic burden to the US healthcare system. There are limited data on the association between length of hospital stay (LOS), readmission rate, and overall costs in patients who underwent primary percutaneous coronary intervention for STEMI. Methods and Results All STEMI hospitalizations were selected in the Nationwide Readmissions Database from 2010 to 2014. From the patients who underwent primary percutaneous coronary intervention, we examined the 30-day outcomes including readmission, mortality, reinfarction, repeat revascularization, and hospital charges/costs according to LOS (1-2, 3, 4, 5, and >5 days) stratified by infarct locations. The 30-day readmission rate after percutaneous coronary intervention for STEMI was 12.0% in the anterior wall (AW) STEMI group and 9.9% in the non-AW STEMI group. Patients with a very short LOS (1-2 days) were readmitted less frequently than those with a longer LOS regardless of infarct locations. However, patients with a very short LOS had significantly increased 30-day readmission mortality versus an LOS of 3 days (hazard ratio, 1.91; CI, 1.16-3.16 [P=0.01]) only in the AW STEMI group. Total costs (index admission+readmission) were the lowest in the very short LOS cohort in both the AW STEMI group (P<0.001) and the non-AW STEMI group (P<0.001). Conclusions For patients who underwent primary percutaneous coronary intervention for STEMI, a very short LOS was associated with significantly lower 30-day readmission and lower cumulative cost. However, a very short LOS was associated with higher 30-day mortality compared with at least a 3-day stay in the AW STEMI cohort.

Impact of the COVID-19 pandemic on interventional cardiology fellowship training in the New York metropolitan area: A perspective from the United States epicenter. Catheter Cardiovasc Interv 2020; 97:201-205.

Abstract
Background The healthcare burden posed by the coronavirus disease 2019 (COVID‐19) pandemic in the New York Metropolitan area has necessitated the postponement of elective procedures resulting in a marked reduction in cardiac catheterization laboratory (CCL) volumes with a potential to impact interventional cardiology (IC) fellowship training. Methods We conducted a web‐based survey sent electronically to 21 Accreditation Council for Graduate Medical Education accredited IC fellowship program directors (PDs) and their respective fellows. Results Fourteen programs (67%) responded to the survey and all acknowledged a significant decrease in CCL procedural volumes. More than half of the PDs reported part of their CCL being converted to inpatient units and IC fellows being redeployed to COVID‐19 related duties. More than two‐thirds of PDs believed that the COVID‐19 pandemic would have a moderate (57%) or severe (14%) adverse impact on IC fellowship training, and 21% of the PDs expected their current fellows' average percutaneous coronary intervention (PCI) volume to be below 250. Of 25 IC fellow respondents, 95% expressed concern that the pandemic would have a moderate (72%) or severe (24%) adverse impact on their fellowship training, and nearly one‐fourth of fellows reported performing fewer than 250 PCIs as of March 1st. Finally, roughly one‐third of PDs and IC fellows felt that there should be consideration of an extension of fellowship training or a period of early career mentorship after fellowship. Conclusions The COVID‐19 pandemic has caused a significant reduction in CCL procedural volumes that is impacting IC fellowship training in the NY metropolitan area. These results should inform professional societies and accreditation bodies to offer tailored opportunities for remediation of affected trainees.

Abstract
Background:
By virtue of its proximity to structures vital to cardiac conduction, aortomitral continuity calcification (AMCC) may help identify patients at highest risk for developing atrioventricular conduction disease requiring permanent pacemaker implantation (PPMI). We aim to determine the association of AMCC and need for PPMI after transcatheter aortic valve replacement.
Methods:
Of 614 patients who underwent transcatheter aortic valve replacement (11.8% PPMI rate), we included 136 patients (age 85±8 years, 47% male) without a preexisting intracardiac device or prior valve surgery who underwent preprocedural computed tomography. We analyzed for the presence of AMCC, aortic valve calcification, and mitral annular calcification as well as quantified AMCC and aortic valve calcification score using the Agatston method. We further stratified AMCC score into 3 categories: 0, 1 to 300, and >300. End point was PPMI at 1 month after transcatheter aortic valve replacement.
Results:
There were 51 (38%) new PPMIs (median time to PPMI, 5 days). Patients who underwent PPMI had a higher prevalence of AMCC than patients without PPMI (69% versus 32%;
P
<0.0001), as well as higher median AMCC score (263 versus 0;
P
<0.0001). There was no difference in aortic valve calcification and mitral annular calcification between patients with and without PPMI (all
P
≥0.09). Patients with AMCC had a 4-fold increase in odds for PPMI compared with those without (adjusted odds ratio, 4.0;
P
=0.0026). Compared with patients with an AMCC score of 0, patients with an AMCC score >300 had greater than a 5-fold increased odds for PPMI (adjusted odds ratio, 5.7;
P
=0.0016).
Conclusions:
Presence of AMCC, particularly with AMCC score >300, is associated with the need for PPMI after transcatheter aortic valve replacement.

Abstract
Background Readmission after ST-segment-elevation myocardial infarction ( STEMI ) poses an enormous economic burden to the US healthcare system. Efforts to prevent readmissions should be based on understanding the timing and causes of these readmissions. This study aimed to investigate contemporary causes, timing, and cost of 30-day readmissions after STEMI . Methods and Results All STEMI hospitalizations were selected in the Nationwide Readmissions Database ( NRD ) from 2010 to 2014. The 30-day readmission rate as well as the primary cause and cost of readmission were examined. Multivariate regression analysis was performed to identify the predictors of 30-day readmission and increased cumulative cost. From 2010 to 2014, the 30-day readmission rate after STEMI was 12.3%. Within 7 days of discharge, 43.9% were readmitted, and 67.3% were readmitted within 14 days. The annual rate of 30-day readmission decreased by 19% from 2010 to 2014 ( P<0.001). Female sex, AIDS , anemia, chronic kidney disease , collagen vascular disease, diabetes mellitus, hypertension, pulmonary hypertension, congestive heart failure , atrial fibrillation, and increased length of stay were independent predictors of 30-day readmission. A large proportion of patients (41.6%) were readmitted for noncardiac reasons. After multivariate adjustment, 30-day readmission was associated with a 47.9% increase in cumulative cost ( P<0.001). Conclusions Two thirds of patients were readmitted within the first 14 days after STEMI , and a large proportion of patients were readmitted for noncardiac reasons. Thirty-day readmission was associated with an ≈50% increase in cumulative hospitalization costs. These findings highlight the importance of closer surveillance of both cardiac and general medical conditions in the first several weeks after STEMI discharge.

Absence of electrocardiographic left ventricular hypertrophy is associated with increased mortality after transcatheter aortic valve replacement. Clin Cardiol 2018; 41:1246-1251.

Abstract
BACKGROUND Electrocardiographic (ECG) left ventricular hypertrophy (LVH) has been associated with increased mortality in patients with asymptomatic aortic stenosis (AS) and hypertension. However, patients with symptomatic AS undergoing transcatheter aortic valve replacement (TAVR) have higher percentages of myocardial fibrosis or amyloidosis that have been associated with decreased ECG voltage and worse outcomes. HYPOTHESIS We tested the hypothesis that baseline ECG LVH is independently associated with increased all-cause mortality after TAVR. METHODS A total of 231 patients (96 men; mean age 84.7 ± 7.8 years) that underwent TAVR at our institution were included. Cornell voltage, defined as SV3 + RaVL, was used to assess for presence of ECG LVH using gender-specific cut-off values. We used the Kaplan-Meier estimator to derive survival curves. Multivariate Cox regression analysis was used to compare mortality between patients without vs with ECG LVH and adjust for echocardiographic LVH and predictors of mortality in this cohort. RESULTS Over a follow-up time of 16.3 ± 10.4 months, the absence of ECG LVH was significantly associated with increased mortality (40.4% vs 23.6% at 2-years, log rank P = 0.003). After adjusting for echocardiographic LVH and predictors of mortality in our cohort, the absence of ECG LVH remained a predictor of increased mortality (HR = 1.79, CI 95% 1.02-3.14, P = 0.042). CONCLUSIONS The absence of ECG LVH was independently associated with increased mortality in patients undergoing TAVR. Baseline ECG may have an important prognostic role in these patients and could lead to further testing to evaluate for myocardial fibrosis or amyloidosis.

Abstract
OBJECTIVES The aim of this study was to compare trends and outcomes of 3 approaches to carotid revascularization in the coronary artery bypass graft (CABG) population when performed during the same hospitalization. BACKGROUND The optimal approach to managing coexisting severe carotid and coronary disease remains controversial. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are used to decrease the risk of stroke in patients with carotid disease undergoing CABG surgery. METHODS The authors conducted a serial, cross-sectional study with time trends of 3 revascularization groups during the same hospital admission: 1) combined CEA+CABG; 2) staged CEA+CABG; and 3) staged CAS+CABG from the Nationwide Inpatient Sample database 2004 to 2012. The primary composite endpoints were in-hospital all-cause death, stroke, and death/stroke. RESULTS During the 9-year period, 22,501 concurrent carotid revascularizations and CABG surgeries during the same hospitalization were performed. Of these, 15,402 (68.4%) underwent combined CEA+CABG, 6,297 (28.0%) underwent staged CEA+CABG, and 802 (3.6%) underwent staged CAS+CABG. The overall rate of CEA+CABG decreased by 16.1% (ptrend = 0.03) from 2004 to 2012, whereas the rate of CAS+CABG did not significantly change during these years (ptrend = 0.10). The adjusted risk of death was greater, whereas risk of stroke was lower with both combined CEA+CABG (death odds ratio [OR]: 2.08, 95% confidence interval [CI]: 1.08 to 3.97; p = 0.03; stroke OR: 0.65, 95% CI: 0.42 to 1.01; p = 0.06) and staged CEA+CABG (death OR: 2.40, 95% CI: 1.43 to 4.05; p = 0.001; stroke OR: 0.50, 95% CI: 0.31 to 0.80; p = 0.004) approaches compared with CAS+CABG. The adjusted risk of death or stroke was similar in the 3 groups. CONCLUSIONS In patients with concomitant carotid and coronary disease undergoing combined revascularization, combined CEA+CABG is utilized most frequently, followed by staged CEA+CABG and staged CAS+CABG strategies. The staged CAS+CABG strategy was associated with lower risk of mortality, but higher risk of stroke. Future studies are needed to examine the risks/benefits of different carotid revascularization strategies for high-risk patients requiring concurrent CABG.

Transapical transcatheter aortic valve replacement in patients with or without prior coronary artery bypass graft operation. J Cardiothorac Surg 2016; 11:158. [PMID: 27899140 PMCID: PMC5129212 DOI: 10.1186/s13019-016-0551-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2016] [Accepted: 11/23/2016] [Indexed: 11/10/2022] Open
Abstract
Background Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. Methods A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed. Patients were classified as having prior CABG (n = 45) or no prior CABG (n = 81). Baseline clinical characteristics, in-hospital, 30-day, 6 months and one-year clinical outcomes were compared. Results Compared to patients without prior CABG, CABG patients were more likely to be male (62.2 vs. 29.6%, p < 0.001) with a higher STS score (11.66 ± 5.47 vs. 8.99 ± 4.19, p = 0.003), history of myocardial infarction (55 vs. 21.1%, p < 0.001), implantable cardioverter defibrillator (17.8 vs. 3.7%, p = 0.017), left main coronary artery disease (42.2 vs. 4.9%, p < 0.001), and proximal left anterior descending coronary artery stenosis (57.8 vs. 16%, p < 0.001). They also presented with a lower left ventricular ejection fraction (%) (42.3 ± 15.3 vs. 54.3 ± 11.6, p < 0.01) and a larger effective valve orifice area (0.75 ± 0.20 cm2 vs. 0.67 ± 0.14 cm2, p = 0.025). There were no intra-procedural deaths, no differences in stroke (0 vs. 1.2%, p = 1.0), procedure time in hours (3.50 ± 0.80 vs. 3.26 ± 0.86, p = 0.127), re-intubation rate (8.9 vs. 8.6% p = 1.0), and renal function (highest creatinine value 1.73 ± 0.71 mg/ml vs.1.88 ± 1.15 mg/ml, p = 0.43). All-cause mortality at 6 months was similar in both groups (11.4, vs. 17.3% p = 0.44), and one-year survival was 81.8 and 77.8% respectively (p = 0.51). On multivariate analysis, the only factor significantly associated with one-year mortality was prior history of stroke (HR, 2.76; 95% CI, 1.06-7.17, p = 0.037). Conclusion Despite the higher baseline clinical risk profile, patients with history of prior CABG undergoing TA-TAVR had comparable in-hospital, 6 months and one-year clinical outcomes to those without prior CABG.

Comparison of Recent Trends in Patients With and Without Major Depression and Acute ST-Elevation Myocardial Infarction. Am J Cardiol 2016; 118:779-784. [PMID: 27453511 DOI: 10.1016/j.amjcard.2016.06.051] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2016] [Revised: 06/14/2016] [Accepted: 06/14/2016] [Indexed: 12/11/2022]
Abstract
Depression has been associated with adverse outcomes after acute coronary syndrome, including ST-elevation myocardial infarction (STEMI). However, trends over time in the incidence and inhospital treatment of STEMI for patients with co-morbid depression in the current era are unknown. We conducted a serial, cross-sectional analysis of patients with STEMI (weighted n = 3,057,998) in the National Inpatient Sample from 2003 to 2012. We examined trends in STEMI incidence and percutaneous coronary intervention (PCI) for patients with and without depression. We used multivariate logistic regression to assess observed differences and to explore trends in inhospital mortality. Depression was present in 153,180 (5%) of the sample. Patients with depression were more likely to be female (55% vs 37%), of white race (86% vs 78%), and had lower crude mortality (12.0% vs 14.2%; p <0.001 for all). Over time, STEMI incidence decreased 52% in patients without depression (p for trend <0.001) but remained stable in those with depression (p for trend 0.74). Although the use of PCI increased in all subgroups over the study duration (p for trend <0.001), depression was associated with lower adjusted odds of PCI (odds ratio 0.90, 95% confidence interval 0.89 to 0.92, p <0.001). In conclusion, in contrast to the wider population, the incidence of STEMI is not decreasing in patients with co-morbid depression. Patients with STEMI and co-morbid depression are less likely to receive revascularization therapy with PCI. These concerning differences warrant further attention.

Abstract
OBJECTIVE To examine peri-procedural and long-term outcomes in patients with chronic kidney disease (CKD) undergoing percutaneous coronary interventions (PCI). BACKGROUND Patients with advanced CKD are considered high risk when undergoing PCI. Limited published data exist on quantifying risk and assessment of long-term outcomes after PCI in this group. METHODS Examining the Cornell Coronary Registry, we prospectively collected data of 6,478 consecutive patients who underwent elective or urgent PCI between 2009 and 2013. Patients were grouped into CKD stages by estimated glomerular filtration rate (eGFR) according to KDOQI guidelines. Procedural and 30-day outcomes are reported with assessment of long-term differences in 5-year all-cause mortality. RESULTS Patients were grouped by CKD stages: 1,351 patients with eGFR ≥90 mL/min/1.73 m2 (stage 1), 2,882 with eGFR 60-89 (stage 2), 1,742 with eGFR 30-59 (stage 3), 191 with eGFR 15-29 (stage 4), and 312 with eGFR <15 or on dialysis (stage 5). The incidence of post-procedural acute heart failure, stroke, new dialysis requirement, transfusions, and bleeding events were higher in patients with greater CKD stage (P < 0.05). Five-year Kaplan-Meier overall survival among CKD stages 1-5 was 98.1, 95.5, 91.8, 82.5, and 76.9%, respectively (P < 0.001 by log-rank test). The hazard ratios of all-cause mortality for CKD stages 2-5 as compared to stage 1 by multivariate Cox regression analysis were as follows: 1.32 (P = 0.26), 2.04 (P < 0.01), 2.79 (P < 0.01), and 5.49 (P < 0.001). CONCLUSION Among patients undergoing PCI, lower GFR is associated with decreased long-term survival. © 2016 Wiley Periodicals, Inc.

Gender Differences in In-Hospital Outcomes After Coronary Artery Bypass Grafting. Am J Cardiol 2016; 118:362-8. [PMID: 27269585 DOI: 10.1016/j.amjcard.2016.05.004] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2016] [Revised: 05/04/2016] [Accepted: 05/04/2016] [Indexed: 12/21/2022]
Abstract
Women historically have a greater risk of operative mortality than men after coronary artery bypass grafting (CABG). There is paucity of contemporary data in gender outcomes of surgical revascularization and understanding modifiable factors that contribute to gender differences are critical for quality improvement and practice change. We, therefore, sought to examine whether the gender gap in CABG outcomes is closing in the contemporary era by conducting a retrospective analysis from the Nationwide Inpatient Sample database from 2003 to 2012. We included all patients who underwent isolated CABG surgery (n = 2,272,998; female n = 623,423 [27.4%]; male n = 1,649,575 [72.6%]). The annual rate of CABG surgeries decreased by 53.7% in men and 57.8% in women over the 10-year study period. Although internal mammary artery use in women was less frequent than in men in 2003 (77.4% vs 81.9%, p <0.001), a significant uptrend closed this gap by 2012 (86.2% vs 87.0%, ptrend 0.003). Overall, unadjusted in-hospital mortality was greater in women (3.2% vs 1.8%, p <0.001). Female gender remained an independent predictor of mortality after multivariate adjustment (odds ratio 1.40, 95% CI 1.36 to 1.43, p <0.001) across all age groups. However, in-hospital mortality decreased at a faster rate in women (3.8% to 2.7%, RR -29.1%, ptrend 0.002) than in men (2.2% to 1.6%, RR -25.7%, ptrend <0.001) from 2003 to 2012. In conclusion, CABG rates in the United States are decreasing over time, yet in-hospital mortality continues to improve. Women have worse in-hospital outcomes than men; however, the gender gap is slowly closing.

Abstract
BACKGROUND Recent studies have shown improving survival after cardiac arrest. However, data regarding sex-based disparities in treatment and outcomes after cardiac arrest are limited. METHODS AND RESULTS We performed a retrospective analysis of all patients suffering cardiac arrest between 2003 and 2012 using the Nationwide Inpatient Sample database. Annual rates of cardiac arrest, rates of utilization of coronary angiography/percutaneous coronary interventions/targeted temperature management, and sex-based outcomes after cardiac arrest were examined. Among a total of 1 436 052 discharge records analyzed for cardiac arrest patients, 45.4% (n=651 745) were females. Women were less likely to present with ventricular tachycardia/ventricular fibrillation arrests compared with men throughout the study period. The annual rates of cardiac arrests have increased from 2003 to 2012 by 14.0% (Ptrend<0.001) and ventricular tachycardia/ventricular fibrillation arrests have increased by 25.9% (Ptrend<0.001). Women were less likely to undergo coronary angiography, percutaneous coronary interventions, or targeted temperature management in both ventricular tachycardia/ventricular fibrillation and pulseless electrical activity/asystole arrests. Over a 10-year study period, there was a significant decrease in in-hospital mortality in women (from 69.1% to 60.9%, Ptrend<0.001) and men (from 67.2% to 58.6%, Ptrend<0.001) after cardiac arrest. In-hospital mortality was significantly higher in women compared with men (64.0% versus 61.4%; adjusted odds ratio 1.02, P<0.001), particularly in the ventricular tachycardia/ventricular fibrillation arrest cohort (49.4% versus 45.6%; adjusted odds ratio 1.11, P<0.001). CONCLUSIONS Women presenting with cardiac arrests are less likely to undergo therapeutic procedures, including coronary angiography, percutaneous coronary interventions, and targeted temperature management. Despite trends in improving survival after cardiac arrest over 10 years, women continue to have higher in-hospital mortality when compared with men.

Abstract
BACKGROUND Hospitalizations for heart failure with preserved ejection fraction (HFpEF) are increasing. There are limited data examining national trends in patients hospitalized with HFpEF. METHODS Using the Nationwide Inpatient Sample, we examined 5,046,879 hospitalizations with a diagnosis of acute heart failure in 2003-2012, stratifying hospitalizations by HFpEF and heart failure with reduced ejection fraction (HFrEF). Patient and hospital characteristics, in-hospital mortality, and length of stay were examined. RESULTS Compared with HFrEF, those with HFpEF were older, more commonly female, and more likely to have hypertension, atrial fibrillation, chronic lung disease, chronic renal failure, and anemia. Over time, HFpEF comprised increasing proportions of men and patients aged ≥75 years. In-hospital mortality rate for HFpEF decreased by 13%, largely due to improved survival in those aged ≥65 years. Multivariable regression analyses showed that pulmonary circulation disorders, liver disease, and chronic renal failure were independent predictors of in-hospital mortality, whereas treatable diseases including hypertension, coronary artery disease, and diabetes were inversely associated. CONCLUSIONS This study represents the largest cohort of patients hospitalized with HFpEF to date, yielding the following observations: number of hospitalizations for HFpEF was comparable with that of HFrEF; patients with HFpEF were most often women and elderly, with a high burden of comorbidities; outcomes appeared improved among a subset of patients; pulmonary hypertension, liver disease, and chronic renal failure were strongly associated with poor outcomes.

Abstract
OBJECTIVES We sought to examine whether baseline diastolic dysfunction (DD) is associated with increased mortality in patients who develop aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR). BACKGROUND Significant post-TAVR AI is associated with increased mortality, likely secondary to adverse hemodynamics secondary to volume overload and decreased LV compliance from chronic pressure overload. However, the effect of baseline DD on outcomes of patients with post-TAVR AI has not been studied. METHODS A total of 195 patients undergoing TAVR were included in the study. Patients with moderate-to-severe mitral stenosis, prior mitral valve replacement or atrial fibrillation were excluded. DD was classified at baseline by a 2-step approach as recommended by the American Society of Echocardiography while AI was evaluated 30 days post-TAVR. Follow up data up to 2 years post-TAVR was used in survival analysis. RESULTS Patients with severe baseline DD who developed ≥mild post-TAVR AI had increased mortality compared to all other patients (HR = 3.89, CI: 1.76-8.6, P = 0.001), which remained significant after adjusting for post-TAVR AI, pre-TAVR AI, baseline mitral regurgitation, ejection fraction, pulmonary artery pressure, creatinine clearance and history of stroke. CONCLUSIONS Even mild post-TAVR AI may have a negative impact on outcomes of patients with underlying severe DD. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Paravalvular aortic regurgitation (PAR) remains a common complication following transcatheter aortic valve replacement (TAVR), and has been associated with increased mortality. Adverse left ventricular (LV) remodelling has been reported in patients with post-TAVR PAR, but the association between adverse LV remodeling and increased mortality remains unclear. The aim of the present study was to examine the association between PAR, LV remodeling and mortality following TAVR in a non-PARTNER (Placement of Aortic Transcatheter Valves) trial population. METHODS A total of 195 patients that underwent TAVR was included in the study. The LV ejection fraction (LVEF), LV mass index (LVMI), LV internal dimension at systole (LVIDs) and diastole (LVIDd) were compared between patients with different degrees of PAR at baseline, and at one month and one year after TAVR. Survival analysis was performed for different degrees of PAR and LV remodeling. RESULTS PAR ≥moderate was associated with increased mortality (HR 4.58 [1.80-11.63], p = 0.001), but PAR >mild was not. The LVIDd and LVIDs were persistently increased at one year after TAVR in patients with PAR >mild compared to those with PAR ≤mild (5.9 ± 0.8 cm versus 5.4 ± 0.7 cm, p = 0.02 and 4.4 ± 0.8 cm versus 3.9 ± 0.8, p = 0.03, respectively). The LVEF was improved similarly between the two groups at one year after TAVR (p = 0.1). Patients with PAR ≥moderate had significantly more adverse LV remodeling at one month after TAVR in terms of LVIDd, LVIDs, and LVMI. The degree of remodeling as expressed in terms of LVIDd, LVIDs, LVMI and LVEF changes from baseline did not have a direct impact on mortality. CONCLUSIONS A worse PAR was associated with more adverse LV remodeling and a higher mortality after TAVR in a non-PARTNER patient population.

Abstract
IMPORTANCE Many patients undergo cardiac catheterization and/or percutaneous coronary intervention (PCI) before noncardiac surgery even though these procedures are not routinely indicated. Data on this cohort of patients are limited. OBJECTIVE To describe the characteristics, angiographic findings, and treatment patterns of clinically stable patients undergoing cardiac catheterization and/or PCI before noncardiac surgery in a large national registry. DESIGN, SETTING, AND PARTICIPANTS This study is a retrospective, descriptive analysis of National Cardiac Data Registry CathPCI Registry diagnostic catheterization and PCI data from July 1, 2009, through December 31, 2014. Data analysis was performed from April 21, 2015, to January 4, 2016. The study included 194 444 patients from 1046 sites who underwent coronary angiography before noncardiac surgery. Patients with acute coronary syndrome, cardiogenic shock, cardiac arrest, or emergency catheterization were excluded. MAIN OUTCOMES AND MEASURES Demographic characteristics, preprocedure noninvasive testing results, angiographic findings, and treatment recommendations are summarized. Among the 27 838 patients who underwent PCI, procedural details, inpatient outcomes, and discharge medications are reported. RESULTS Of the 194 444 included patients, 113 590 (58.4%) were male, the median age was 65 years (interquartile range, 57-73 years), and 162 532 (83.6%) were white. Most were overweight or obese (152 849 [78.6%]), and 78 847 (40.6%) had diabetes mellitus. Most patients were asymptomatic (117 821 [60.6%]), although 112 302 (57.8%) had been taking antianginal medications within 2 weeks of the procedure. Prior noninvasive stress testing was reported in 126 766 (65.2%), and results were positive in 109 458 (86.3%) of those with stress data. Obstructive disease was present in 93 447 (48.1%). After diagnostic angiography, revascularization with PCI or bypass surgery was recommended in 46 380 patients (23.8%) in the overall cohort, 27 191 asymptomatic patients (23.1%), and 45 083 patients with obstructive disease (48.3%). In the 27 191 patients undergoing PCI, 367 treated lesions (1.3%) were in the left main artery and 3831 (13.8%) in the proximal left anterior descending artery. A total of 11 366 patients (40.8%) received drug-eluting stents. Complications occurred in a few patients, with a catheterization-related mortality rate of 0.05%. CONCLUSIONS AND RELEVANCE In the largest contemporary US cohort reported to date, most patients undergoing diagnostic catheterization before noncardiac surgery are asymptomatic. The discovery of obstructive coronary artery disease is common, and although randomized clinical trials have found no benefit in outcomes, revascularization is recommended in nearly half of these patients. The overall findings highlight management patterns in this population and the need for greater evidence-based guidelines and practices.

Comparison of Trends in Incidence, Revascularization, and In-Hospital Mortality in ST-Elevation Myocardial Infarction in Patients With Versus Without Severe Mental Illness. Am J Cardiol 2016; 117:1405-10.

Abstract
Patients with severe mental illness (SMI), including schizophrenia and bipolar disorder, are at elevated risk of ST-elevation myocardial infarction (STEMI) but have previously been reported as less likely to receive revascularization. To study the persistence of these findings over time, we examined trends in STEMI incidence, revascularization, and in-hospital mortality for patients with and without SMI in the National Inpatient Sample from 2003 to 2012. We further used multivariate logistic regression analysis to assess the odds of revascularization and in-hospital mortality. SMI was present in 29,503 of 3,058,697 (1%) of the STEMI population. Patients with SMI were younger (median age 58 vs 67 years), more likely to be women (44% vs 38%), and more likely to have several co-morbidities, including diabetes, chronic pulmonary disease, substance abuse, and obesity (p <0.001 for all). Over time, STEMI incidence significantly decreased in non-SMI (p for trend <0.001) but not in SMI (p for trend 0.14). Revascularization increased in all subgroups (p for trend <0.001) but remained less common in SMI. In-hospital mortality decreased in non-SMI (p for trend = 0.004) but not in SMI (p for trend 0.10). After adjustment, patients with SMI were less likely to undergo revascularization (odds ratio 0.59, 95% CI 0.52 to 0.61, p <0.001), but SMI was not associated with increased in-hospital mortality (odds ratio 0.97, 95% CI 0.93 to 1.01, p = 0.16). In conclusion, in contrast to the overall population, the incidence of STEMI is not decreasing in patients with SMI. Despite changes in the care of STEMI, patients with SMI remain less likely to receive revascularization therapies.

Abstract
With the rapid advance of transcatheter aortic valve implantation (TAVI), it is important to evaluate the relationship between TAVI volumes and outcomes. The aim of this study was to analyze in-hospital outcomes after TAVI stratified according to hospital volumes. Using the National Inpatient Sample files from 2012, hospitals performing transfemoral (TF)-TAVI and transapical (TA)-TAVI were divided into high-volume and low-volume centers. A total of 7,660 patients underwent TAVI in 256 hospitals in 2012. In the TF-TAVI cohort, multivariate logistic regression analyses demonstrated that low TF-TAVI volume status was an independent predictor of death and bleeding. In the TA-TAVI cohort, low volume status was a predictor of death, myocardial infarction, and need for permanent pacemaker. In addition, hospitals that performed low TA-TAVI volume were associated with significantly higher rate of death after surgical aortic valve replacement in comparison with the hospitals that perform high TA-TAVI volume (3.6% vs 2.3%, p <0.001). In conclusion, centers with lower volume of TAVI had more frequent adverse events compared with higher volume centers.

Abstract
BACKGROUND Following percutaneous coronary intervention (PCI), elevations in serum creatinine level and declines in glomerular filtration rate are common. Prior studies have demonstrated benefit of chronic statin therapy in the prevention of contrast-induced nephropathy (CIN); however, it is unknown whether chronic statin therapy reduces the incidence of CIN in the non-emergent PCI setting. METHODS Using the 2004-2005 Cornell Angioplasty Registry, a total of 1171 consecutive patients were selected for analysis. The population was divided into two groups: (1) patients on chronic (≥30 days) statin therapy prior to PCI (n = 874); and (2) patients not on chronic statin therapy (n = 297). RESULTS Patients taking chronic statin therapy were more likely to have diabetes mellitus (35.7% vs 22.6%; P<.001), previous myocardial infarction (36.3% vs 20.5%; P<.001), previous PCI (38.9% vs 16.2%; P<.001), and previous coronary artery bypass graft surgery (19.5% vs 11.4%; P=.01). Statin users were also more likely to be taking long-term aspirin (77.8% vs 59.6%; P<.001) and clopidogrel therapy (29.9% vs 14.1%; P<.001). Baseline serum creatinine levels were comparable between the two groups, as were procedural characteristics. The incidence of CIN following PCI was not significantly different between patients on chronic statin therapy versus those not on chronic statin therapy (4.2% vs 5.4%; P=.42). However, after multivariate adjustment, chronic statin therapy was associated with a lower incidence of CIN (odds ratio [OR], 0.21; 95% confidence interval [CI], 0.05-0.94; P=.04). Acute heart failure on admission and the urgency of the procedure (urgent vs elective PCI) were also independent predictors for developing CIN (OR, 3.04; 95% CI, 1.45-6.66 [P=.01] and OR, 2.80; 95% CI, 1.42-5.55 [P=.01], respectively). Long-term mortality rates were similar between those on chronic statin therapy and those not on statins. CONCLUSION CIN occurred in 4.5% of patients following non-emergent PCI. Multivariate analysis demonstrated that chronic statin therapy decreased the odds of developing CIN in patients undergoing PCI.

Trends in hospital treatments for peripheral arterial disease in the United States and association between payer status and quality of care/outcomes, 2007-2011. Catheter Cardiovasc Interv 2015; 86:864-72.

Abstract
OBJECTIVE This study sought to identify the temporal trends of presenting diagnoses and vascular procedures performed for peripheral arterial disease (PAD) along with the rates of procedures and in-hospital outcomes by payer status. BACKGROUND Previous studies suggest that patients with Medicare, Medicaid, or lack of insurance receive poorer quality of care leading to worse outcomes. METHODS We analyzed 196,461,055 discharge records to identify all hospitalized patients with PAD records (n=1,687,724) from January 2007 through December 2011 in the Nationwide Inpatient Sample database. RESULTS The annual frequency of vascular procedures remained unchanged during the study period. Patients with Medicaid were more likely to present with gangrenes, whereas patients with Medicare were more likely to present with ulcers. After adjustment, patients with Medicare and Medicaid were more likely to undergo amputations when compared with private insurance/HMO (OR=1.13, 95% CI=1.10-1.16 and OR=1.24, 95% CI=1.20-1.29, respectively). Patients with both Medicare and Medicaid were less likely to undergo bypass surgery (OR=0.82, 95% CI=0.81-0.84 and OR=0.87, 95% CI=0.85-0.90, respectively), but more likely to undergo endovascular procedures (OR=1.18, 95% CI=1.17-1.20 and OR=1.03, 95% CI=1.01-1.06, respectively). Medicare and Medicaid status versus private insurance/HMO was associated with worse adjusted odds of in-hospital outcomes, including mortality after amputations, endovascular procedures, and bypass surgeries. CONCLUSIONS In this analysis, patients with Medicare and Medicaid had more comorbid conditions at baseline when compared with private insurance/HMO cohorts, were more likely to present with advanced stages of PAD, undergo amputations, and develop in-hospital complications. These data unveil a critical gap and an opportunity for quality improvement in the elderly and those with poor socioeconomic status.

Abstract
BACKGROUND Recent reports have suggested that advanced age may preclude favorable outcomes in transcatheter aortic valve replacement (TAVR), particularly when performed via transapical (TA) access. However, detailed examinations of TA-TAVR in nonagenarian patients are lacking in the contemporary literature. We therefore describe our experience with 25 consecutive nonagenarians who underwent TA-TAVR and report their short- and mid-term outcomes. METHODS We identified all patients 90 years old or greater who underwent TA-TAVR between 2009-2014 at our institution. Demographic, comorbidity and echocardiographic data were obtained for all patients as were their in-hospital, 30-day, and 1-year outcomes. Overall survival was calculated using the Kaplan-Meier method. RESULTS The mean Society of Thoracic Surgeons' predicted risk of mortality was 10.2% (SD±3.4). Twenty-four nonagenarians received TA-TAVR secondary to severe aortic stenosis while 1 had a valve-in-valve procedure for a regurgitant bioprosthetic valve. There were no conversions to open surgery, no aborted procedures, and no in-hospital deaths or strokes; 44% of patients (N.=11) were discharged to home. Five patients required cardiac rehospitalization within the first 30 days and 2 experienced strokes during the first year. Overall 30-day and 1-year survival were 100% and 83%, respectively. CONCLUSIONS TA-TAVR can safely be performed on nonagenarians subjected to otherwise standard selection criteria. Chronology should not stand as a routine contraindication to this procedure; rather, comorbidities and functional status should define patient eligibility for TA-TAVR.

Abstract
BACKGROUND AND AIM OF THE STUDY Multidetector computed tomography (MDCT) is widely used for transcatheter aortic valve replacement (TAVR) planning, and its use predicts and prevents complications. To date, the reproducibility of aortoiliofemoral measurements and prediction of fluoroscopic angles for TAVR deployment remain inadequately studied. METHODS Twenty-five consecutive patients (six males, 19 females; mean age 81.1 years) undergoing pre-procedural evaluation for TAVR were studied for 74 separate variables by MDCT. Two experienced readers made repeated measurements of the diameter and area of the aortic annulus, the aortic root at the level of the sinuses of Valsalva, sinotubular junction, and ascending aorta, and the diameters of peripheral vessels at the level of the distal abdominal aorta, and the iliofemoral arteries. A fluoroscopic angle prediction was obtained for left anterior oblique (LAO) 0 degrees, 20 degrees and 30 degrees projections. Pearson's correlation coefficient (r) was obtained, and intra-class correlation coefficients and Bland-Altman plots were generated to examine agreements, respectively. RESULTS The mean aortic valve area was 0.7 cm2. Each measurement generally showed good intra- and inter-observer reproducibility. The mean difference between readers was -0.3 mm for mean annular diameter and 3.6 mm2 for annular area. The area- derived diameter showed better reproducibility than the mean diameter (ICC 0.87, 0.84). However, the right coronary artery height showed poor inter-observer agreement (ICC 0.48). Angle predictions for 0 degrees, 20 degrees and 30 degrees-LAO were reproducible within and between readers (ICC 0.68-0.96 and 0.75-0.85). Qualitative assessments were also reliable between readers. CONCLUSION Inter- and intra-observer measurements of the pre-TAVR planning parameters are reliable, with generally a high degree of agreement.

Costs and in-hospital outcomes of transcatheter aortic valve implantation versus surgical aortic valve replacement in commercial cases using a propensity score matched model. Am J Cardiol 2015; 115:1443-7. [PMID: 25784513 DOI: 10.1016/j.amjcard.2015.02.026] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Revised: 02/13/2015] [Accepted: 02/13/2015] [Indexed: 10/24/2022]
Abstract
The aim of this study was to compare in-hospital cost and outcomes between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). TAVI is an effective treatment option in patients with symptomatic aortic stenosis who are at high risk for traditional SAVR. Several studies using trial data or outside United States registry data have addressed TAVI cost issues, although there is a paucity of cost data involving commercial cases in the United States. Using Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project Nationwide Inpatient Sample files, a propensity score-matched analysis of all commercial TAVI and SAVR cases performed in 2011 was conducted. Overall hospital cost and length of stay, as well as procedural complications, were compared between the 2 matched cohorts: 595 TAVI patients were matched to 1,785 SAVR patients in a 1:3 ratio. There was no difference in mean ($181,912 vs $196,298) or median ($152,993 vs $155,974) hospital cost between TAVI and SAVR (p = 0.60). The TAVI group had significantly shorter lengths of hospital stay than the SAVR group (mean 9.76 vs 12.01 days, p <0.001). There was no difference in postprocedural in-hospital death or stroke, but TAVI patients were more likely to have bleeding complications, to have vascular complications, and to require pacemakers. In conclusion, when analyzing in-hospital cost of commercial TAVI and SAVR cases using the Nationwide Inpatient Sample data set, TAVI is an economically satisfactory alternative to SAVR and results in an approximately 2-day shorter length of stay during the index hospitalization.

Abstract
Although the benefit of percutaneous coronary interventions (PCIs) for patients presenting with acute coronary syndromes (ACS) has been established in numerous studies, the role of PCI in stable coronary artery disease (CAD) remains controversial. With the publication of the Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluations trial and the appropriate use criteria for coronary artery revascularization, we sought to examine the impact of these treatment strategies and guidelines on the current practice of PCI in United States. We conducted a serial cross-sectional study with time trends of patients undergoing PCI for ACS and stable CAD from 2007 to 2011. The annual rate of all PCI decreased by 27.7% from 10,785 procedures per million adults per year in 2007 to 2008 to 7,801 procedures per million adults per year in 2010 to 2011 (p=0.03). Although there was no statistically significant decrease in the PCI utilization for ACS from 2007 to 2011, PCI utilization for stable CAD decreased by 51.7% (from 2,056 procedures per million adults per year in 2008 to 992 procedures per million adults per year in 2011, p=0.02). Hospitals with a higher volume of PCI experienced a more significant decrease. Decrease in PCI utilization for stable CAD was statistically significant for patients with Medicare and private insurance/health maintenance organization (44.5%, p=0.03 and 59.5%, p=0.007, respectively). In conclusion, the rate of PCI decreased substantially starting from 2009 in the United States. Most of the decrease was attributed to the reduction in PCI utilization for stable CAD.

Abstract
BACKGROUND Radial access for percutaneous coronary intervention (r-PCI) is associated with reduced vascular complications; however, previous reports have shown that <2% of percutaneous coronary intervention (PCI) procedures in the United States are performed via the radial approach. Our aims were to evaluate temporal trends in r-PCI and compare procedural outcomes between r-PCI and transfemoral PCI. METHODS AND RESULTS We conducted a retrospective cohort study from the CathPCI registry (n=2 820 874 procedures from 1381 sites) between January 2007 and September 2012. Multivariable logistic regression models were used to evaluate the adjusted association between r-PCI and bleeding, vascular complications, and procedural success, using transfemoral PCI as the reference. Outcomes in high-risk subgroups such as age ≥75 years, women, and patients with acute coronary syndrome were also examined. The proportion of r-PCI procedures increased from 1.2% in quarter 1 2007 to 16.1% in quarter 3 2012 and accounted for 6.3% of total procedures from 2007 to 2012 (n=178 643). After multivariable adjustment, r-PCI use in the studied cohort of patients was associated with lower risk of bleeding (adjusted odds ratio, 0.51; 95% confidence interval, 0.49-0.54) and lower risk of vascular complications (adjusted odds ratio, 0.39; 95% confidence interval, 0.31-0.50) in comparison with transfemoral PCI. The reduction in bleeding and vascular complications was consistent across important subgroups of age, sex, and clinical presentation. CONCLUSIONS There has been increasing adoption of r-PCI in the United States. Transradial PCI now accounts for 1 of 6 PCIs performed in contemporary clinical practice. In comparison with traditional femoral access, transradial PCI is associated with lower vascular and bleeding complication rates.

Abstract
OBJECTIVES This study sought to compare short- and long-term (4-year) outcomes in patients with and without peripheral vascular disease (PVD) following non-emergent percutaneous coronary intervention (PCI) in current clinical practice. BACKGROUND Patients with PVD undergoing coronary revascularization have high rates of adverse short-term outcomes. However, the long-term clinical outcomes of patients with PVD undergoing PCI in the contemporary drug-eluting stent (DES) era have not been well characterized. METHODS The 2004/2005 Cornell Angioplasty Registry database was used to evaluate the in-hospital and long-term clinical outcomes in patients undergoing non-emergent (urgent or elective) PCI. A total of 2455 study patients were examined. We excluded patients presenting with an ST-elevation myocardial infarction (MI) ≤ 24 hours, hemodynamic instability/shock, thrombolytic therapy ≤ 7 days, or renal insufficiency (creatinine ≥ 4 mg/dL). Mean clinical follow-up was 4.4 ± 1.1 years. RESULTS Of the 2455 patients, a total of 173 (7%) had PVD and 2282 (93%) had no reported history of PVD. DESs were used in 87% of the PCIs. The incidence of in-hospital death (1.8% vs 0.1%; P=.006) was greater in the PVD group, whereas postprocedural MI (6.4% vs 6.8%; P=.810) and major adverse cardiovascular event rates including death, stroke, emergent coronary artery bypass graft/PCI, and MI (8.7% vs 7.0%; P=.360) were similar in the PVD versus no PVD groups. Long-term Kaplan-Meier survival (89.2% vs 76.2%; P<.001) was significantly higher in patients without PVD versus with PVD, respectively. After adjustment with a multivariate Cox regression analysis, long-term all-cause survival was similar in patients with versus without PVD (hazard ratio, 1.16; 95% confidence interval, 0.69-1.93; P=.581). CONCLUSIONS In contemporary PCI utilizing DESs, glycoprotein IIb/IIIa inhibitors, and clopidogrel, PVD is associated with a higher in-hospital and 4-year all-cause mortality. In our study, this difference in long-term survival was mainly driven by a higher rate of comorbidities in the PVD population that underwent PCI.

Abstract
Periprocedural statin therapy has been shown to decrease the rate of myocardial infarctions (MIs) after percutaneous coronary intervention (PCI). However, the impact of long-term statin therapy on postprocedure MI remains unknown. We examined the impact of long-term statin therapy on cardiac enzyme (cardiac troponin I [cTnI] and creatine kinase-MB [CK-MB]) increases after PCI in patients undergoing nonemergency PCI. Using the 2004/2005 Cornell Angioplasty Registry, we evaluated 1,482 patients undergoing elective or urgent PCI with normal preprocedure cardiac enzymes levels (cTnI and CK-MB). The population was divided into 2 groups: (1) patients on long-term (≥7 days) statin therapy before PCI (n = 1,073) and (2) patients not on long-term statin regimen (n = 409). Cardiac enzyme levels after PCI were assessed at 8, 12, and 18 hours after PCI. An increase in cTnI ≥1 time upper-limit of normal (ULN) was observed in 830 patients (56.1%) and an increase in cTnI ≥3 times ULN was observed in 518 patients (35.0%). There was no difference in incidence of cTnI increases ≥3 times ULN in patients on long-term statin therapy versus those not on long-term statin therapy in the overall group (35.1% vs 34.5%, p = 0.855). There was a trend toward a lower incidence of small cTnI increases ≥1 time ULN in patients on long-term statin therapy versus those not receiving long-term statins (54.6% vs 59.7%, p = 0.090). Incidence of CK-MB increases ≥1 time or ≥3 times ULN and peak cTnI and CK-MB levels were similar between the 2 groups. In a subgroup of patients with unstable angina, long-term statin therapy decreased small cTnI increases (≥1 time ULN) after PCI (54.6% vs 64.3%, p = 0.023). The greatest benefit in decrease of MIs after PCI was seen in patients with unstable angina receiving long-term high-dose statin therapy. In conclusion, long-term statin therapy did not decrease the incidence of periprocedural MI in patients with stable coronary artery disease undergoing nonemergency PCI. In patients with unstable coronary syndromes, long-term statin therapy may be beneficial, particularly at a high dose.

Abstract
OBJECTIVES The aim of this meta-analysis was to assess the prevalence and prognostic value regarding mortality of cTnT or cTnI elevations after nonemergent percutaneous coronary intervention (PCI) in a large number of cohort/registry studies. BACKGROUND Routine cardiac troponin measurement after elective PCI has been controversial among interventionalists. Recent studies have provided conflicting data in regard to predictive value of cardiac troponin-T (cTnT) and troponin-I (cTnI) elevation after non-emergent PCI. METHODS Electronic and manual searches were conducted of all published studies reporting on the prognostic impact of cTnT or cTnI elevation after elective PCI. A meta-analysis was performed with all-cause mortality at follow-up as the primary endpoint. RESULTS We identified 22 studies, involving 22,353 patients, published between 1998 and 2009. Postprocedural cTnT and cTnI were elevated in 25.9% and 34.3% of patients, respectively. Follow-up period ranged from 3 to 67 months (mean: 17.7 ± 14.9 months). The results showed no heterogeneity among the trials (Q-test: 25.39; I(2) : 17%; P = 0.23). No publication bias was detected (Egger's test: P = 0.16). The long-term all-cause mortality in patients with cTnI or cTnT elevation after PCI (5.8%) was significantly higher when compared to patients without cTnI or cTnT elevation (4.4%); OR 1.45 (95% CI: 1.22-1.72), P < 0.01. In addition, the postprocedural composite adverse clinical events of all-cause mortality or myocardial infarction (MI) in patients with cTnI or cTnT elevation after PCI (9.2%) was significantly higher when compared to patients without cTnI or cTnT elevation (5.3%); OR 1.77 (95% CI: 1.48-2.11), P < 0.01. CONCLUSIONS The current meta-analysis indicates that cTnI or cTnT elevation after nonemergent PCI is indicative of an increase in long-term all-cause mortality as well as the composite adverse events of all-cause mortality and MI. Efforts to routinely monitor periprocedural cTn levels along with more intensive outpatient monitoring/treatment of patients with cTn elevations may help to improve the long-term adverse outcomes in these patients following non-emergent PCI.

Abstract
OBJECTIVES This study sought to investigate if the efficacy of bivalirudin monotherapy is similar to heparin plus GP IIb/IIIa inhibition in patients with acute coronary syndromes (ACS) treated with clopidogrel following diagnostic angiography. BACKGROUND Prior trials have demonstrated that peri-procedural bivalirudin therapy confers similar efficacy as heparin plus GP IIb/IIIa inhibitors, while lowering the risk of bleeding complications in ACS patients undergoing percutaneous coronary interventions (PCI). However, the incidence of adverse ischemic events post-PCI appeared to be higher in patients receiving bivalirudin without adequate pretreatment with clopidogrel. METHODS Using the 2004/2005 Cornell Angioplasty Registry, we evaluated 980 consecutive patients undergoing urgent PCI for UA/NSTEMI who were treated with either bivalirudin or UFH plus GP IIb/IIIa inhibitor. We excluded patients who were on chronic clopidogrel therapy or received clopidogrel pretreatment prior to angiography. All patients received a clopidogrel load (≥300-mg dose) immediately before or after the PCI. Long-term all-cause mortality was obtained for 100% of patients, with a mean follow-up of 24.6 ± 7.7 months. RESULTS Of the 980 study patients, 461 (47.0%) were treated with bivalirudin and 519 (53.0%) patients received UFH plus GP IIb/IIIa inhibitor. DES were used in 88% of PCI; 45% of patients presented with NSTEMI. The incidence of in-hospital death (0.4% vs. 0.2%, P = 0.604), post-procedural MI (6.9% vs. 5.4%, P = 0.351), and MACE including death, stroke, emergent CABG/PCI, and MI (7.6% vs. 5.8%, P = 0.304) were similar in patients treated with bivalirudin versus UFH plus GP IIb/IIIa inhibitors, respectively. The incidence of in-hospital stent thrombosis was similar (0.7% vs. 0%, P = 0.104), while major (0.9% vs. 2.9%, P = 0.034) and minor bleeding (10.4% vs. 18.9%, P < 0.001) was reduced in the bivalirudin-treated group. By two-years of follow-up, after propensity-score adjusted multivariate Cox regression analysis, there was no significant difference in long-term mortality between the two groups (HR 1.18; 95%CI 0.64-2.19, P = 0.598). CONCLUSIONS In patients presenting with ACS and receiving clopidogrel treatment after angiography (before or within 30 min of PCI), peri-procedural bivalirudin monotherapy suppresses acute and long-term adverse events to a similar extent as does UFH plus GP IIb/IIIa inhibitors, while significantly lowering the risk of bleeding complications.
