2023 AHA/ACC/ACCP/ASPC/NLA/PCNA Guideline for the Management of Patients With Chronic Coronary Disease: A Report of the American Heart Association/American College of Cardiology Joint Committee on Clinical Practice Guidelines.

AIM: The "2023 AHA/ACC/ACCP/ASPC/NLA/PCNA Guideline for the Management of Patients With Chronic Coronary Disease" provides an update to and consolidates new evidence since the "2012 ACCF/AHA/ACP/AATS/PCNA/SCAI/STS Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease" and the corresponding "2014 ACC/AHA/AATS/PCNA/SCAI/STS Focused Update of the Guideline for the Diagnosis and Management of Patients With Stable Ischemic Heart Disease." METHODS: A comprehensive literature search was conducted from September 2021 to May 2022. Clinical studies, systematic reviews and meta-analyses, and other evidence conducted on human participants were identified that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. STRUCTURE: This guideline provides an evidenced-based and patient-centered approach to management of patients with chronic coronary disease, considering social determinants of health and incorporating the principles of shared decision-making and team-based care. Relevant topics include general approaches to treatment decisions, guideline-directed management and therapy to reduce symptoms and future cardiovascular events, decision-making pertaining to revascularization in patients with chronic coronary disease, recommendations for management in special populations, patient follow-up and monitoring, evidence gaps, and areas in need of future research. Where applicable, and based on availability of cost-effectiveness data, cost-value recommendations are also provided for clinicians. Many recommendations from previously published guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Transcatheter edge-to-edge mitral valve repair for mitral regurgitation in patients with cardiogenic shock: A systematic review and meta-analysis.

BACKGROUND: There is currently little evidence for transcatheter edge-to-edge mitral valve repair (TEER) for mitral regurgitation (MR) in patients with cardiogenic shock (CS). Therefore, this study investigated the characteristics and outcomes of CS patients who underwent TEER for MR. METHODS: PubMed, EMBASE were searched in July 2023. Case series and observational studies reporting clinical characteristics and outcomes in CS patients with MR who underwent TEER were included. We performed a one-group meta-analysis using a random effects model. RESULTS: A total of 4060 patients from 7 case series and 5 observational studies were included. The mean age was 68.2 (95% confidence interval [CI]: 64.1-72.2) years, and 41.4% of patients (95% CI: 39.1%-43.7%) were female. Pre-TEER, severe MR was present in 85.3% (95% CI: 76.1%-91.3%) of patients. Mean left ventricular ejection fraction was 36.7% (95% CI: 29.2%-44.2%), and 54.6% (95% CI: 36.9%-71.2%) of patients received mechanical circulatory support. The severity of MR post-TEER was less than 2+ in 88% (95% CI: 87%-89%) of patients. In-hospital mortality was 11% (95% CI: 10%-13%), whereas 30-day and 1-year mortality rates were 15% (95% CI: 13%-16%), and 36% (95% CI: 21%-54%), respectively. CONCLUSIONS: This systematic review and meta-analysis assessed the clinical characteristics and outcomes of TEER in CS patients with MR. TEER for MR in patients with CS has been successful in reducing MR in most of the patients, but with a high mortality rate. Randomized controlled trials of TEER for MR and CS are needed.

Long-term outcomes after transcatheter aortic valve replacement: Meta-analysis of Kaplan-Meier-derived data.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is as an alternative treatment to surgical AVR, but the long-term outcomes of TAVR remain unclear. AIMS: This study aimed to analyze long-term outcomes following TAVR using meta-analysis. METHODS: A literature search was performed with MEDLINE, EMBASE, Cochrane Library, Web of Science, and Google Scholar through November 2022; studies reporting clinical outcomes of TAVR with follow-up periods of ≥8 years were included. The outcomes of interest were overall survival and/or freedom from structural valve deterioration (SVD). Surgical risk was assessed with the Society of Thoracic Surgeons (STS) predicted risk of mortality (PROM) score. A subgroup analysis was conducted for intermediate-/high-surgical risk patients only. RESULTS: Eleven studies including 5458 patients were identified and analyzed. The mean age was 82.0 ± 6.5 years, and mean STS PROM score ranged from 2.9 to 10.6%. Survival rate at 5 and 10 years was 47.7% ± 1.4% and 12.1 ± 2.0%. Five studies including 1509 patients were analyzed for SVD. Freedom from SVD at 5 and 8 years was 95.5 ± 0.7% and 85.1 ± 3.1%. Similar results for survival and SVD were noted in the subgroup analysis of intermediate-/high-risk patients. CONCLUSIONS: Following TAVR, approximately 88% of patients died within 10 years, whereas 85% were free from SVD at 8 years. These date suggest that baseline patient demographic have the greatest impact on survival, and SVD does not seem to have a prognostic impact in this population. Further investigations on longer-term outcomes of younger and lower-risk patients are warranted.

Global, Regional, and National Burden of Calcific Aortic Valve and Degenerative Mitral Valve Diseases, 1990-2017.

BACKGROUND: Nonrheumatic valvular diseases are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease Study 2017, mortality, prevalence, and disability-adjusted life-years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease, and other nonrheumatic valvular diseases were estimated for 195 countries and territories from 1990 to 2017. METHODS: Vital registration data, epidemiologic survey data, and administrative hospital data were used to estimate disease burden using the Global Burden of Disease Study modeling framework, which ensures comparability across locations. Geospatial statistical methods were used to estimate disease for all countries, because data on nonrheumatic valvular diseases are extremely limited for some regions of the world, such as Sub-Saharan Africa and South Asia. Results accounted for estimated level of disease severity as well as the estimated availability of valve repair or replacement procedures. DALYs and other measures of health-related burden were generated for both sexes and each 5-year age group, location, and year from 1990 to 2017. RESULTS: Globally, CAVD and degenerative mitral valve disease caused 102 700 (95% uncertainty interval [UI], 82 700-107 900) and 35 700 (95% UI, 30 500-42 500) deaths, and 12.6 million (95% UI, 11.4 million-13.8 million) and 18.1 million (95% UI, 17.6 million-18.6 million) prevalent cases existed in 2017, respectively. A total of 2.5 million (95% UI, 2.3 million-2.8 million) DALYs were estimated as caused by nonrheumatic valvular diseases globally, representing 0.10% (95% UI, 0.09%-0.11%) of total lost health from all diseases in 2017. The number of DALYs increased for CAVD and degenerative mitral valve disease between 1990 and 2017 by 101% (95% UI, 79%-117%) and 35% (95% UI, 23%-47%), respectively. There is significant geographic variation in the prevalence, mortality rate, and overall burden of these diseases, with highest age-standardized DALY rates of CAVD estimated for high-income countries. CONCLUSIONS: These global and national estimates demonstrate that CAVD and degenerative mitral valve disease are important causes of disease burden among older adults. Efforts to clarify modifiable risk factors and improve access to valve interventions are necessary if progress is to be made toward reducing, and eventually eliminating, the burden of these highly treatable diseases.

Association of Acute Kidney Injury with Outcomes in Patients Undergoing Transcatheter Mitral Valve Repair.

INTRODUCTION: Although transcatheter mitral valve repair (TMVr) is a contrast-free procedure, prior single-center studies have demonstrated a high incidence of acute kidney injury (AKI) following TMVr. The main objective of this study was to examine risk factors for AKI, and its association with outcomes in patients undergoing TMVr. METHODS: We queried the National Readmission Database to identify TMVr procedures performed between January 2014 and December 2017. Complex samples multivariable logistic and linear regression models were used to identify risk factors associated with AKI, as well as to determine the association between AKI and clinical outcomes (in-hospital mortality, index length of stay (LOS), 30-day all-cause readmissions, and 30-day heart failure [HF] readmissions). RESULTS: Of 14,623 patients who underwent TMVr during the study period, 2,001 (13.6%) had a diagnosis of AKI. HF, chronic kidney disease, chronic liver disease, fluid/electrolyte disorder, weight loss, nonelective admission, cardiogenic shock, and bleeding/transfusion were independently associated with an increased risk of AKI. In patients undergoing TMVr, AKI was associated with an increased risk of in-hospital mortality (adjusted odds ratio [aOR], 4.94; 95% confidence interval [CI], 2.92-8.34), 30-day all-cause readmissions (aOR, 1.91; 95% CI, 1.49-2.46), 30-day HF readmissions (aOR, 2.30; 95% CI, 1.38-3.84), and longer index LOS (adjusted parameter estimate, 5.78; 95% CI, 5.26-6.41). CONCLUSION: AKI in the setting of TMVr is common and is associated with worse clinical outcomes. Further studies are needed to determine if optimizing renal function prior to TMVr may improve outcomes, as well as to understand the impact of TMVr itself on renal function.

Cardiac implantable electronic device placement following alcohol septal ablation for hypertrophic cardiomyopathy in the United States.

BACKGROUND: Cardiac implantable electronic devices (CIED) are sometimes required after alcohol septal ablation (ASA) for hypertrophic cardiomyopathy (HCM). The primary objectives of this study were to characterize the incidence, timing, and predictors of CIED placement after ASA for HCM. METHODS: Patients were identified from the 2010-2015 Nationwide Readmissions Databases. Incidence, timing and independent predictors of CIED placement, as well as 30-day readmission rates were examined. RESULTS: There were 1296 patients (national estimate = 2864) with HCM who underwent ASA. CIED were implanted in 322 (25% overall; 14% permanent pacemaker, 11% implantable cardioverter defibrillator) during the index hospitalization. Of these, 21%, 23%, 21%, and 18% occurred on postprocedure day 0, 1, 2, and 3, respectively. Only 17 (1.3%) patients underwent CIED implantation between discharge and 30-day follow up. Independent predictors of index hospitalization CIED implantation included older age, diabetes, heart failure, nonelective index hospital admission and hospitalization at a privately owned hospital. Nonelective 30-day readmission rates among those who did and did not undergo CIED placement during their index hospitalization, were 6.8% and 7.9%, respectively (p = .53); median time to readmission was also similar between groups. CONCLUSIONS: One in four HCM patients undergoing ASA underwent CIED implantation during their index hospitalization; nearly 2/3rd during the first 48 h postprocedure. Private hospital ownership independently predicted CIED placement. More data are needed to better understand the unexpectedly high rates of CIED placement, earlier than anticipated timing of implantation and differential rates by hospital ownership.

Thirty-day readmissions after transcatheter versus surgical mitral valve repair in high-risk patients with mitral regurgitation: Analysis of the 2014-2015 Nationwide readmissions databases.

OBJECTIVE: Determine the rates, reasons, predictors, and costs of 30-day readmissions following transcatheter mitral valve repair (TMVR) versus surgical mitral valve repair (SMVR) in the United States. BACKGROUND: Data on 30-day readmissions after TMVR are limited. METHODS: High-risk patients with mitral regurgitation (MR) undergoing TMVR or SMVR were identified from the 2014-2015 Nationwide Readmissions Databases. Multivariable stepwise regression models were used to identify independent predictors of 30-day readmission. Risk of 30-day readmission was compared between the two groups using univariate and propensity score adjusted regression models. RESULTS: Among 8,912 patients undergoing mitral valve repair during 2014-2015 (national estimate 17,809), we identified 7,510 (84.7%) that underwent SMVR and 1,402 (15.3%) that underwent TMVR. Thirty-day readmission rates after SMVR and TMVR were 10.7% and 11.7%, respectively (unadjusted OR 1.11, 95% CI 0.89-1.39, p = .35). After propensity score adjustment, TMVR was associated with a lower risk of 30-day readmissions compared with SMVR (adjusted OR 0.70, 95% CI 0.51-0.95, p = .02). Heart failure and arrhythmias were the leading cardiac reasons for readmission. Anemia and fluid and electrolyte disorder were independent predictors of 30-day readmission after TMVR. Demographics, comorbidities, and length of stay were independent predictors of 30-day readmission after SMVR. CONCLUSIONS: One in 10 patients are readmitted within 30 days following TMVR or SMVR. Approximately half of the readmissions are for cardiac reasons. The predictors of 30-day readmission are different among patients undergoing TMVR and SMVR, but can be easily screened for to identify patients at highest risk for readmission.

Predictors of Contrast Volume in Transcatheter Aortic Valve Replacement.

BACKGROUND: Contrast-induced acute kidney injury (CIAKI) is a frequent and serious complication of transcatheter aortic valve replacement (TAVR). The most important procedural risk factor for CIAKI is contrast volume. OBJECTIVES: Because contrast volume is a modifiable factor that directly predicts CIAKI, we sought to identify predictors of increased contrast volume in TAVR patients. Identification of such predictors may allow both prediction and mitigation of CIAKI risk following TAVR. METHOD: We retrospectively analyzed data from consecutive patients not on hemodialysis who underwent successful TAVR at a single US center from 2013 to 2018. Using multivariable linear regression modelling, we assessed the relationships between contrast volumes and 49 patient and procedural factors hypothesized to be potential predictors. RESULTS: In 295 patients, we identified 17 factors that independently predicted contrast volume, 10 of which contributed 90% of the complete model's r2 value. Procedure year (suggesting a learning curve), aortic insufficiency, radiation dose, prior AVR, and previous pacemaker placement were statistically the most significant predictors of CIAKI. TAVR device and diabetes were notably not predictors. CONCLUSIONS: To predict and reduce contrast use in TAVR, patients at risk for increased contrast volume may be identified using the predictors elucidated in this study. For such patients, strategies for contrast reduction and renal protection may be employed.

Intracardiac vs transesophageal echocardiography for percutaneous left atrial appendage occlusion: A meta-analysis.

INTRODUCTION: Percutaneous left atrial appendage closure (LAAC) is typically performed utilizing transesophageal echocardiography (TEE) and fluoroscopy. Intracardiac echocardiography (ICE) can be a suitable alternative to guide implantation. Given the limited data, we performed a meta-analysis of all studies that compared ICE vs TEE for percutaneous LAAC. METHODS: A comprehensive literature search was performed in PubMed, Embase, Scopus, Google Scholar, and major scientific conference sessions for published abstracts and manuscripts until 1 August 2018. Studies reporting clinical outcomes comparing TEE vs ICE for endocardial LAAC in human subjects aged greater than or equal to 18 years were included. Two investigators independently extracted the data and individual quality assessment was performed. The analysis was performed using Cochrane Collaboration software, RevMan 5.3. RESULTS: Five eligible studies consisting of 1157 patients (ICE-391 patients and TEE-766 patients) were included. Four studies were retrospective and one was prospective, nonrandomized. Two studies included Watchman, two included the Amplatzer Cardiac Plug/Amulet device, and one included both devices. There was no significant difference in CHA2DS2VASC or HAS-BLED scores between both groups. There was no significant difference in acute procedural success between ICE vs TEE (risk ratio, 1.01; 95% CI, 0.99-1.04; P = 0.24). There was no significant difference in fluoroscopy time (mean difference [MD], 1.84 minutes; 95% CI, 0.59-4.27; P = 0.14) and total procedure time (MD, -5.06 minutes; 95% CI, -24.6-14.4; P = 0.61) between both groups. There was also no significant difference in complications including pericardial tamponade, device embolization, and stroke between both groups. CONCLUSION: In our meta-analysis, ICE was as effective as TEE during percutaneous LAAC.

Outcomes of multivessel vs culprit lesion-only percutaneous coronary intervention in patients with acute myocardial infarction complicated by cardiogenic shock: Evidence from an updated meta-analysis.

OBJECTIVES: This updated meta-analysis evaluated outcomes with multi-vessel (MV-PCI) vs culprit lesion-only percutaneous coronary intervention (CL-PCI), in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS). BACKGROUND: There is considerable debate regarding the optimal revascularization strategy in patients with AMI and CS, particularly regarding management of non-culprit lesions. METHODS: Databases were searched for studies comparing MV-PCI and CL-PCI in patients with AMI and CS. The primary outcome of interest was short-term all-cause mortality. Secondary outcomes included long-term mortality, repeat revascularization and myocardial reinfarction. Safety outcomes were stroke, acute renal failure and major bleeding. Pooled odds ratios (OR) and 95% confidence intervals (CI) were estimated using random-effects models. RESULTS: Our meta-analysis consisting of 14 studies (13 observational, 1 RCT) involving 8,552 patients showed that in comparison to CL-PCI, MV-PCI was associated with similar short-term mortality (OR 1.14; 95% CI 0.9-1.43), as well as similar long-term mortality (OR 0.94; 95% CI 0.68-1.28). There was no significant difference in the risk of myocardial reinfarction (OR 1.19; 95% CI 0.76-1.86), or repeat revascularization (OR 0.79; 95% CI 0.41-1.55) between the two groups. Compared to CL-PCI, MV-PCI was associated with a similar risk of bleeding (OR 1.13; 95% CI 0.91-1.40) and stroke (OR 1.28; 95% CI 0.84-1.96), but a higher risk of developing renal failure (OR 1.32; 95% CI 1.05-1.65). CONCLUSIONS: Our meta-analysis suggests that there is a higher risk of renal failure with no additional benefit in efficacy outcomes with MV-PCI, compared to CL-PCI in patients with AMI and CS.

Thirty-day readmission after endovascular or surgical revascularization for chronic mesenteric ischemia: Insights from the Nationwide Readmissions Database.

There are limited contemporary data on readmission after revascularization for chronic mesenteric ischemia (CMI). This study aimed to determine the rates, reasons, predictors, and costs of 30-day readmission after endovascular or surgical revascularization for CMI. Patients with CMI discharged after endovascular or surgical revascularization during 2013 to 2014 were identified from the Nationwide Readmissions Database. The rates, reasons, length of stay, and costs of 30-day all-cause, non-elective, readmission were determined using weighted national estimates. Independent predictors of 30-day readmission were determined using hierarchical logistic regression. Among 4671 patients with CMI who underwent mesenteric revascularization, 19.5% were readmitted within 30 days after discharge at a median time of 10 days. More than 25% of readmissions were for cardiovascular or cerebrovascular conditions, most of which were for peripheral or visceral atherosclerosis and congestive heart failure. Independent predictors of 30-day readmission included non-elective index admission, chronic kidney disease (CKD), and discharge to home healthcare or to a skilled nursing facility. Revascularization modality did not independently predict readmission. In a nationwide, retrospective analysis of patients with CMI undergoing revascularization, approximately one in five were readmitted within 30 days. Predictors were largely non-modifiable and included non-elective index admission, CKD, and discharge disposition.

Risk Calculator to Predict 30-Day Readmission After Coronary Artery Bypass: A Strategic Decision Support Tool.

BACKGROUND: Re-admission is an important source of patient dissatisfaction and increased hospital costs. A simple calculator to determine the probability of re-admission may help guide patient dismissal planning. METHODS: Using the national readmissions database (NRD), we identified admissions for isolated primary coronary artery bypass (CABG) and stratified them according to 30-day readmission. Including pre, intra and postoperative variables, we prepared a logistic regression model to determine the probability for re-admission. The model was tested for reliability with boot-strapping and 10-fold cross-validation. RESULTS: From 135,699 procedures, 19,355 were readmitted at least once within 30days of dismissal. Patients who were readmitted were older (67±10 vs 65 ± 10 years, p<0.01), females (32% vs 24%; p<0.01) and had a higher Elixhauser comorbidity score (1.5±1.4 vs 1.1±1.2; p<0.01). Our final model (c- statistic=0.65) consisted of 16 pre and three postoperative factors. End-stage renal disease (OR 1.79 [1.57-2.04]) and length of stay>9days (OR 1.60 [1.52-1.68]) were most prominent indicators for readmission. Compared to Medicaid beneficiaries, those with private insurance (OR 0.62 [0.57-0.68]) and Medicare (OR 0.85 [0.79-0.92]) coverage were less likely to be readmitted. CONCLUSIONS: Our simple 30-days CABG readmission calculator can be used as a strategic tool to help reduce readmissions after coronary artery bypass surgery.

Thirty-Day Readmissions After Endovascular or Surgical Therapy for Critical Limb Ischemia: Analysis of the 2013 to 2014 Nationwide Readmissions Databases.

BACKGROUND: Thirty-day readmission rates have gained increasing importance as a key quality metric. A significant number of patients are hospitalized for the management of critical limb ischemia (CLI), but limited data are available on the incidence, predictors, and causes of 30-day readmission after hospitalization for CLI. METHODS: Hospitalizations for a primary diagnosis of CLI during which patients underwent endovascular or surgical therapy (revascularization and/or amputation) and were discharged alive were identified in the 2013 to 2014 Nationwide Readmissions Databases. Incidence, reasons, and costs of 30-day unplanned readmissions were determined. Hierarchical logistic regression models were used to identify independent predictors of 30-day readmissions. RESULTS: We included 60 998 (national estimate, 135 110) index CLI hospitalizations (mean age, 68.9±11.9 years; 40.8% women; 24.6% for rest pain, 37.2% for ulcer, and 38.2% for gangrene). The 30-day readmission rate was 20.4%. Presentation with ulcer or gangrene, age ≥65 years, female sex, large hospital size, teaching hospital status, known coronary artery disease, heart failure, diabetes mellitus, chronic kidney disease, anemia, coagulopathy, obesity, major bleeding, acute myocardial infarction, vascular complications, and sepsis were identified as independent predictors of 30-day readmission. Mode of revascularization was not independently associated with readmissions. Infections (23.5%), persistent or recurrent manifestations of peripheral artery disease (22.2%), cardiac conditions (11.4%), procedural complications (11.0%), and endocrine issues (5.7%) were the most common reasons for readmission. The inflation-adjusted aggregate costs of 30-day readmissions for CLI during the study period were $624 million. CONCLUSIONS: Approximately 1 in 5 patients hospitalized for CLI and undergoing revascularization is readmitted within 30 days. Risk of readmission is influenced by CLI presentation, patient demographics, comorbidities, and in-hospital complications, but not by the mode of revascularization.

Catheter ablation of ventricular tachycardia in nonischemic cardiomyopathy: A propensity score-matched analysis of in-hospital outcomes in the United States.

INTRODUCTION: Monomorphic ventricular tachycardia (VT) is an important cause of morbidity and mortality. Use and outcome data of catheter ablation for VT in nonischemic cardiomyopathy (NICM) are limited. METHODS AND RESULTS: We obtained data from the 2003-2014 National Inpatient Sample databases. We used propensity score matching to compare patients undergoing catheter ablation versus medical therapy of VT related to NICM, and described the temporal trends in utilization and in-hospital outcomes of catheter ablation of VT in patients with NICM in the United States. From 2003 to 2014, of 133,529 patients hospitalized with the principal diagnosis of VT in NICM, 14,651 (11.0%) underwent catheter ablation. In this period, there was an increasing trend in utilization of catheter ablation (9.3% in 2003-2004 to 12.1% in 2003-2014, adjusted OR [per year], 1.12; 95% CI, 1.08-1.16; Ptrend  < 0.001). After propensity score matching, in-hospital mortality occurred in 172 of 14,318 (1.2%) patients in the catheter ablation group, compared with 297 of 14,156 (2.1%) of patients undergoing medical therapy (47% lower; 43% relative difference [adjusted OR, 0.53; 95% CI, 0.43-0.66]). CONCLUSIONS: In patients with NICM, catheter ablation of VT is associated with lower in-hospital mortality compared with those managed medically. The utilization rates of CA for VT related to NICM have increased in the past decade. Adequately powered randomized trials will be necessary to confirm these findings.

Transcatheter aortic valve replacement in patients with severe aortic stenosis and heart failure.

Severe aortic stenosis (AS) and heart failure (HF) represent an important and high-risk group of patients who are often referred for transcatheter aortic valve replacement (TAVR) due to high risk for surgical intervention. Thus far, randomized controlled trials have shown comparable outcomes between TAVR and surgical aortic valve replacement in patients with severe AS and heart failure with reduced ejection fraction. In the current review, we will discuss (1) the pathophysiology of HF in patients with severe AS, (2) role of imaging modalities in management, (3) role of biomarkers of HF on prognosis, (4) impact of other valvular heart diseases, (5) evidence from the contemporary trials on the role of TAVR in patients with severe AS and HF, and (6) future directions and research.

Predictors of patient radiation exposure during transcatheter aortic valve replacement.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) exposes patients to radiation. OBJECTIVES: We sought to identify factors associated with higher radiation exposure and to quantify their relative influence, which may inform reduction of this hazard. METHODS: All TAVR procedures at Rhode Island Hospital between March 20, 2012 and February 12, 2017 were included. Procedures were performed by two co-primary operators using a Siemens Artis Zeego system. Radiation metrics were generated by the imaging system. The primary metric was dose-area product (DAP, Gy*cm2 ), and secondary metrics were reference point air kerma (mGy) and fluoroscopy time (minutes). Data collected for the STS/ACC TVT Registry were utilized to develop a multivariable linear regression model predicting DAP. RESULTS: In 294 TAVRs, median DAP was 169 Gy*cm2 [interquartile range (IQR) 106-238]. The r2 values for the full 27-variable DAP model and reduced eight-variable model were 0.457 and 0.420, respectively. Valve area, aortic insufficiency, and procedure year (suggesting absence of a learning curve) were non-significant predictors in the full model, while increasing weight, cutdown transfemoral access, higher pre-procedure creatinine and hemoglobin, and vascular complications predicted higher DAP in both models. Results were unchanged when DAP was log-transformed. Secondary models for air kerma and fluoroscopy time revealed similar predictors. CONCLUSION: Factors associated with increased procedural complexity and duration as well as radiation attenuation and scatter predict increased patient radiation exposure during TAVR. Modification of procedural technique, especially using percutaneous femoral vascular access, may facilitate reduction in exposure.

Global Cardiovascular and Renal Outcomes of Reduced GFR.

The burden of premature death and health loss from ESRD is well described. Less is known regarding the burden of cardiovascular disease attributable to reduced GFR. We estimated the prevalence of reduced GFR categories 3, 4, and 5 (not on RRT) for 188 countries at six time points from 1990 to 2013. Relative risks of cardiovascular outcomes by three categories of reduced GFR were calculated by pooled random effects meta-analysis. Results are presented as deaths for outcomes of cardiovascular disease and ESRD and as disability-adjusted life years for outcomes of cardiovascular disease, GFR categories 3, 4, and 5, and ESRD. In 2013, reduced GFR was associated with 4% of deaths worldwide, or 2.2 million deaths (95% uncertainty interval [95% UI], 2.0 to 2.4 million). More than half of these attributable deaths were cardiovascular deaths (1.2 million; 95% UI, 1.1 to 1.4 million), whereas 0.96 million (95% UI, 0.81 to 1.0 million) were ESRD-related deaths. Compared with metabolic risk factors, reduced GFR ranked below high systolic BP, high body mass index, and high fasting plasma glucose, and similarly with high total cholesterol as a risk factor for disability-adjusted life years in both developed and developing world regions. In conclusion, by 2013, cardiovascular deaths attributed to reduced GFR outnumbered ESRD deaths throughout the world. Studies are needed to evaluate the benefit of early detection of CKD and treatment to decrease these deaths.

The State of US Health, 1990-2016: Burden of Diseases, Injuries, and Risk Factors Among US States.

Introduction: Several studies have measured health outcomes in the United States, but none have provided a comprehensive assessment of patterns of health by state. Objective: To use the results of the Global Burden of Disease Study (GBD) to report trends in the burden of diseases, injuries, and risk factors at the state level from 1990 to 2016. Design and Setting: A systematic analysis of published studies and available data sources estimates the burden of disease by age, sex, geography, and year. Main Outcomes and Measures: Prevalence, incidence, mortality, life expectancy, healthy life expectancy (HALE), years of life lost (YLLs) due to premature mortality, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) for 333 causes and 84 risk factors with 95% uncertainty intervals (UIs) were computed. Results: Between 1990 and 2016, overall death rates in the United States declined from 745.2 (95% UI, 740.6 to 749.8) per 100 000 persons to 578.0 (95% UI, 569.4 to 587.1) per 100 000 persons. The probability of death among adults aged 20 to 55 years declined in 31 states and Washington, DC from 1990 to 2016. In 2016, Hawaii had the highest life expectancy at birth (81.3 years) and Mississippi had the lowest (74.7 years), a 6.6-year difference. Minnesota had the highest HALE at birth (70.3 years), and West Virginia had the lowest (63.8 years), a 6.5-year difference. The leading causes of DALYs in the United States for 1990 and 2016 were ischemic heart disease and lung cancer, while the third leading cause in 1990 was low back pain, and the third leading cause in 2016 was chronic obstructive pulmonary disease. Opioid use disorders moved from the 11th leading cause of DALYs in 1990 to the 7th leading cause in 2016, representing a 74.5% (95% UI, 42.8% to 93.9%) change. In 2016, each of the following 6 risks individually accounted for more than 5% of risk-attributable DALYs: tobacco consumption, high body mass index (BMI), poor diet, alcohol and drug use, high fasting plasma glucose, and high blood pressure. Across all US states, the top risk factors in terms of attributable DALYs were due to 1 of the 3 following causes: tobacco consumption (32 states), high BMI (10 states), or alcohol and drug use (8 states). Conclusions and Relevance: There are wide differences in the burden of disease at the state level. Specific diseases and risk factors, such as drug use disorders, high BMI, poor diet, high fasting plasma glucose level, and alcohol use disorders are increasing and warrant increased attention. These data can be used to inform national health priorities for research, clinical care, and policy.

Global Burden of Hypertension and Systolic Blood Pressure of at Least 110 to 115 mm Hg, 1990-2015.

Importance: Elevated systolic blood (SBP) pressure is a leading global health risk. Quantifying the levels of SBP is important to guide prevention policies and interventions. Objective: To estimate the association between SBP of at least 110 to 115 mm Hg and SBP of 140 mm Hg or higher and the burden of different causes of death and disability by age and sex for 195 countries and territories, 1990-2015. Design: A comparative risk assessment of health loss related to SBP. Estimated distribution of SBP was based on 844 studies from 154 countries (published 1980-2015) of 8.69 million participants. Spatiotemporal Gaussian process regression was used to generate estimates of mean SBP and adjusted variance for each age, sex, country, and year. Diseases with sufficient evidence for a causal relationship with high SBP (eg, ischemic heart disease, ischemic stroke, and hemorrhagic stroke) were included in the primary analysis. Main Outcomes and Measures: Mean SBP level, cause-specific deaths, and health burden related to SBP (≥110-115 mm Hg and also ≥140 mm Hg) by age, sex, country, and year. Results: Between 1990-2015, the rate of SBP of at least 110 to 115 mm Hg increased from 73 119 (95% uncertainty interval [UI], 67 949-78 241) to 81 373 (95% UI, 76 814-85 770) per 100 000, and SBP of 140 mm Hg or higher increased from 17 307 (95% UI, 17 117-17 492) to 20 526 (95% UI, 20 283-20 746) per 100 000. The estimated annual death rate per 100 000 associated with SBP of at least 110 to 115 mm Hg increased from 135.6 (95% UI, 122.4-148.1) to 145.2 (95% UI 130.3-159.9) and the rate for SBP of 140 mm Hg or higher increased from 97.9 (95% UI, 87.5-108.1) to 106.3 (95% UI, 94.6-118.1). For loss of DALYs associated with systolic blood pressure of 140 mm Hg or higher, the loss increased from 95.9 million (95% uncertainty interval [UI], 87.0-104.9 million) to 143.0 million (95% UI, 130.2-157.0 million) [corrected], and for SBP of 140 mm Hg or higher, the loss increased from 5.2 million (95% UI, 4.6-5.7 million) to 7.8 million (95% UI, 7.0-8.7 million). The largest numbers of SBP-related deaths were caused by ischemic heart disease (4.9 million [95% UI, 4.0-5.7 million]; 54.5%), hemorrhagic stroke (2.0 million [95% UI, 1.6-2.3 million]; 58.3%), and ischemic stroke (1.5 million [95% UI, 1.2-1.8 million]; 50.0%). In 2015, China, India, Russia, Indonesia, and the United States accounted for more than half of the global DALYs related to SBP of at least 110 to 115 mm Hg. Conclusions and Relevance: In international surveys, although there is uncertainty in some estimates, the rate of elevated SBP (≥110-115 and ≥140 mm Hg) increased substantially between 1990 and 2015, and DALYs and deaths associated with elevated SBP also increased. Projections based on this sample suggest that in 2015, an estimated 3.5 billion adults had SBP of at least 110 to 115 mm Hg and 874 million adults had SBP of 140 mm Hg or higher.
