OBJECTIVES: To quantify the impact of clopidogrel plus aspirin on the individual outcomes of death, myocardial infarction, or stroke in patients with established cardiovascular disease, or in patients with multiple risk factors for vascular disease. BACKGROUND: Randomized trials have demonstrated a reduction in composite outcomes when clopidogrel is added to aspirin therapy in patients with coronary artery disease; however, the magnitude of benefit on individual outcomes is unknown. METHODS: We conducted a meta-analysis on randomized, controlled trials that compared aspirin plus clopidogrel with aspirin plus placebo for the treatment of coronary artery disease. RESULTS: This analysis included five randomized trials (CURE, CREDO, CLARITY, COMMIT, and CHARISMA) in 79 624 patients. The incidence of all-cause mortality was 6.3% in the aspirin plus clopidogrel group versus 6.7% in the aspirin group (odds ratio [OR] 0.94; 95% CI 0.89, 0.99; p = 0.026). The incidence of myocardial infarction was 2.7% and 3.3% (OR 0.82; 95% CI 0.75, 0.89; p < 0.0001), and stroke was 1.2% and 1.4% (OR 0.82; 95% CI 0.73, 0.93; p = 0.002). Similarly, the incidence of major bleeding was 1.6% and 1.3% (OR 1.26; 95% CI 1.11, 1.41; p < 0.0001), and fatal bleeding was 0.28% and 0.27% (OR 1.04; 95% CI 0.76, 1.43; p = 0.79). CONCLUSION: The addition of clopidogrel to aspirin results in a small reduction in all-cause mortality in patients with ST-elevation myocardial infarction and a modest reduction in myocardial infarction and stroke in patients with cardiovascular disease. The overall incidence of major bleeding however is increased, although there is no excess of fatal bleeds or hemorrhagic strokes. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study sought to determine if the initiation of statin (HMG-CoA reductase inhibitor) therapy during acute coronary syndromes reduces long-term mortality and other adverse cardiac outcomes. BACKGROUND: Initiation of statin therapy during acute coronary syndromes has not been shown to reduce mortality, myocardial infarction or stroke within 4 months of follow-up. METHODS: Clinical trials that randomized patients with acute coronary syndromes to early statin therapy compared with less intensive lipid reduction (placebo/lower-dose statin/usual care), and reported long-term outcomes were included for analysis. RESULTS: In all, there were seven studies (L-CAD, PTT, FLORIDA, Colivicchi et al., PROVE-IT, ESTABLISH, and A-to-Z) with 9553 patients who started statin therapy within 12 days of hospital presentation. The incidence of all-cause mortality was 3.4% in the statin group versus 4.6% in the less intensive lipid reduction group over a weighted mean follow-up of 22.9 months (relative risk [RR] 0.74; 95% CI 0.61, 0.90; p = 0.003). The number of patients needed to treat to prevent one death was 84 patients. Similarly, the incidence of cardiovascular mortality in the statin versus the less intensive lipid reduction group was 2.4% versus 3.3% (RR 0.74; 95% CI 0.58, 0.93; p = 0.010), unstable angina 4.1% versus 5.0% (RR 0.81; 95% CI 0.68, 0.98; p = 0.027), revascularization 11.2% versus 12.9% (RR 0.86; 95% CI 0.78, 0.96; p = 0.006), stroke 1.1% versus 1.2% (RR 0.90; 95% CI 0.62, 1.30; p = 0.56), and myocardial infarction 6.6% versus 7.0% (RR 0.94; 95% CI 0.81, 1.09; p = 0.41). CONCLUSIONS: The benefit of early initiation of statin therapy during acute coronary syndromes slowly accrues over time so that a survival advantage is seen around 24 months. Relatively few patients need to be treated to prevent one death over this time period. Furthermore, this approach significantly reduces unstable angina and the need for revascularization.

Background: There is a paucity of data regarding the relationship between overall hospital volumes for total aortic valve replacement (AVR; transcatheter AVR [TAVR] or surgical AVR [SAVR]) and patient outcomes., Methods and Results: We queried the 2019 Nationwide Readmission Database for patients undergoing AVR. Based on procedural volumes of TAVR or SAVR, we classified hospitals as high (≥50th percentile) or low (<50th percentile) volume centers and categorized hospitals as high TAVR/high SAVR, high TAVR/low SAVR, high SAVR/low TAVR, and low TAVR/low SAVR. Multivariable regression models were employed. The main study outcomes were in-hospital mortality and 30-day readmission after total AVR. Our final analysis included 72 123 patients undergoing AVR at 400 hospitals across the United States. The median (interquartile range) hospital procedural volumes for total AVR, TAVR, and SAVR were 137 (86-210), 82 (50-127), and 56 (31-87) procedures, respectively. There was an inverse correlation between hospital procedural volumes of AVR, TAVR, or SAVR and in-hospital mortality after total AVR but not with 30-day readmission. Using high TAVR/high SAVR hospitals as reference, there was higher in-hospital mortality after total AVR among low TAVR/low SAVR hospitals (adjusted odds ratio [OR], 1.29 [95% CI, 1.07-1.56]) but similar in-hospital mortality among high TAVR/low SAVR hospitals and low TAVR/high SAVR volumes. There was no difference in 30-day readmission rates after total AVR among the 4 hospital categories., Conclusions: Nationwide data revealed that in-hospital mortality after total AVR (SAVR or TAVR) is inversely related to hospital total volumes of AVR. Patients with aortic stenosis have better outcomes if they are managed among experienced centers with high case volumes of both TAVR and SAVR.

Renal denervation as an option for difficult to treat hypertension has been a concept for several decades, with recent U.S. FDA approval of new, minimally invasive devices. However, while renal denervation has the potential to improve hypertension management, several challenges require consideration prior to widespread adoption. The effect relative to sham control is modest, and generally similar to addition of a single blood pressure lowering medication. It is possible that with additional technique refinement greater effects may be possible. Key factors to consider beyond the direction, strengths, and limitations of the renal denervation technologies themselves, are an understanding of patient groups that derive greatest benefit and phenotypes or biomarkers that predict greater response. This review provides an update on these challenges in addition to the current state and future of renal denervation within the context of hypertension management and treatment., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Background: Contemporary research in peripheral artery disease (PAD) remains limited due to lack of a national registry and low accuracy of diagnosis codes to identify PAD patients in electronic health records., Methods & Results: Leveraging a novel natural language processing (NLP) system that identifies PAD with high accuracy using ankle brachial index (ABI) and toe-brachial index (TBI) values, we created a registry of 103,748 patients with new onset PAD patients in the Veterans Health Administration (VHA). Study endpoints include mortality, cardiovascular (hospitalization for acute myocardial infarction or stroke) and limb events (hospitalization for critical limb ischemia or major amputation) and were identified using VA and non-VA encounters. The mean age was 70.6 years; 97.3% were males, and 18.5% self-identified as Black race. The mean ABI value was 0.78 (SD: 0.26) and the mean TBI value was 0.51 (SD: 0.19). Nearly one-third (32.4%) patients were currently smoking and 35.4% formerly smoked. Prevalence of hypertension (86.6%), heart failure (22.7%), diabetes (54.8%), renal failure (23.6%), and chronic obstructive pulmonary disease (35.4%) was high. At 1-year, 9.4% of patients had died. The 1-year incidence of cardiovascular events was 5.6 per 100 patient-years and limb events was 4.5 per 100 patient-years., Conclusions: We have successfully launched a registry of >100,000 patients with a new diagnosis of PAD in the VHA, the largest integrated health system in the U.S. The ncidence of death and clinical events in our cohort is high. Ongoing studies will yield important insights regarding improving care and outcomes in this high-risk group.

Cardiogenic shock after acute myocardial infarction (AMI-CS) carries significant mortality despite advances in revascularization and mechanical circulatory support. We sought to identify the process-based and structural characteristics of centers with lower mortality in AMI-CS. We analyzed 16,337 AMI-CS cases across 440 centers enrolled in the National Cardiovascular Data Registry's Chest Pain-MI Registry, a retrospective cohort database, between January 1, 2015, and December 31, 2018. Centers were stratified across tertiles of risk-adjusted in-hospital mortality rate (RAMR) for comparison. Risk-adjusted multivariable logistic regression was also performed to identify hospital-level characteristics associated with decreased mortality. The median participant age was 66 (interquartile range 57 to 75) years, and 33.0% (n = 5,390) were women. The median RAMR was 33.4% (interquartile range 26.0% to 40.0%) and ranged from 26.9% to 50.2% across tertiles. Even after risk adjustment, lower-RAMR centers saw patients with fewer co-morbidities. Lower-RAMR centers performed more revascularization (92.8% vs 90.6% vs 85.9%, p <0.001) and demonstrated better adherence to associated process measures. Left ventricular assist device capability (odds ratio [OR] 0.78 [0.67 to 0.92], p = 0.002), more frequent revascularization (OR 0.93 [0.88 to 0.98], p = 0.006), and higher AMI-CS volume (OR 0.95 [0.91 to 0.99], p = 0.009) were associated with lower in-hospital mortality. However, several such characteristics were not more frequently observed at low-RAMR centers, despite potentially reflecting greater institutional experience or resources. This may reflect the heterogeneity of AMI-CS even after risk adjustment. In conclusion, low-RAMR centers do not necessarily exhibit factors associated with decreased mortality in AMI-CS, which may reflect the challenges in performing outcomes research in this complex population., Competing Interests: Declaration of competing interest Dr. Bhatt discloses the following relationships - Advisory Board: Angiowave, Bayer, Boehringer Ingelheim, CellProthera, Cereno Scientific, Elsevier Practice Update Cardiology, High Enroll, Janssen, Level Ex, McKinsey, Medscape Cardiology, Merck, MyoKardia, NirvaMed, Novo Nordisk, PhaseBio, PLx Pharma, Stasys; Board of Directors: American Heart Association New York City, Angiowave (stock options), Bristol-Meyers Squibb (stock), DRS.LINQ (stock options), High Enroll (stock); Consultant: Broadview Ventures, GlaxoSmithKline, Hims, SFJ, Youngene; Data Monitoring Committees: Acesion Pharma, Assistance Publique-Hôpitaux de Paris, Baim Institute for Clinical Research (formerly Harvard Clinical Research Institute, for the PORTICO trial, funded by St. Jude Medical, now Abbott), Boston Scientific (Chair, PEITHO trial), Cleveland Clinic, Contego Medical (Chair, PERFORMANCE 2), Duke Clinical Research Institute, Mayo Clinic, Mount Sinai School of Medicine (for the ENVISAGE trial, funded by Daiichi Sankyo; for the ABILITY-DM trial, funded by Concept Medical; for ALLAY-HF, funded by Alleviant Medical), Novartis, Population Health Research Institute; Rutgers University (for the NIH-funded MINT trial); Honoraria: American College of Cardiology (Senior Associate Editor, Clinical Trials and News, ACC.org; Chair, ACC Accrediation Oversight Committee), Arnold and Porter law firm (work related to Sanofi/Bristol-Meyers Squibb clopidogrel litigation), Baim Institute for Clinical Research (formerly Harvard Clinical Research Institute; RE-DUAL PCI clinical trial steering committee funded by Boehringer Ingelheim; AEGIS-II executive committee funded by CSL Behring), Belvoir Publications (Editor in Chief, Harvard Heart Letter), Canadian Medical and Surgical Knowledge Translation Research Group (clinical trial steering committees), CSL Behring (AHA lecture), Cowen and Company, Duke Clinical Research Institute (clinical trial steering committees, including for the PRONOUNCE trial, funded by Ferring Pharmaceuticals), HMP Global (Editor in Chief, Journal of Invasive Cardiology), Journal of the American College of Cardiology (Guest Editor; Associate Editor), K2P (Co-Chair, interdisciplinary curriculum), Level Ex, Medtelligence/ReachMD (CME steering committees), MJH Life Sciences, Oakstone CME (Course Director, Comprehensive Review of Interventional Cardiology), Piper Sandler, Population Health Research Institute (for the COMPASS operations committee, publications committee, steering committee, and USA national co-leader, funded by Bayer), WebMD (CME steering committees), Wiley (steering committee); Other: Clinical Cardiology (Deputy Editor); Patent: Sotagliflozin (named on a patent for sotagliflozin assigned to Brigham and Women's Hospital who assigned to Lexicon; neither I nor Brigham and Women's Hospital receive any income from this patent); Research Funding: Abbott, Acesion Pharma, Afimmune, Aker Biomarine, Alnylam, Amarin, Amgen, AstraZeneca, Bayer, Beren, Boehringer Ingelheim, Boston Scientific, Bristol-Meyers Squibb, Cardax, CellProthera, Cereno Scientific, Chiesi, CinCor, Cleerly, CSL Behring, Eisai, Ethicon, Faraday Pharmaceuticals, Ferring Pharmaceuticals, Forest Laboratories, Fractyl, Garmin, HLS Therapeutics, Idorsia, Ironwood, Ischemix, Janssen, Javelin, Lexicon, Lilly, Medtronic, Merck, Moderna, MyoKardia, NirvaMed, Novartis, Novo Nordisk, Otsuka, Owkin, Pfizer, PhaseBio, PLx Pharma, Recardio, Regeneron, Reid Hoffman Foundation, Roche, Sanofi, Stasys, Synaptic, The Medicines Company, Youngene, 89Bio; Royalties: Elsevier (Editor, Braunwald's Heart Disease); Site Co-Investigator: Abbott, Biotronik, Boston Scientific, CSI, Endotronix, St. Jude Medical (now Abbott), Philips, SpectraWAVE, Svelte, Vascular Solutions; Trustee: American College of Cardiology; Unfunded Research: FlowCo. oooo Dr. Fonarow reports consulting for Abbott, Amgen, AstraZeneca, Bayer, Cytokinetics, Edwards, Janssen, Medtronic, Merck, and Novartis.

Introduction: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic cause of myocardial infarction. Migraine headache has been reported to be common among patients with SCAD, but the degree of migraine-related disability has not been quantified., Methods: Clinical data and headache variables were obtained from the baseline assessment of the prospective, multicenter iSCAD Registry. Migraine-related disability was quantified using the self-reported Migraine Disability Assessment (MIDAS). Demographic, clinical, psychosocial, and medical characteristics from data entry forms were compared between patients with and without migraine., Results: Of the 773 patients with available data, 46% reported previous or current migraines. Those with migraines were more likely to be women (96.9% vs 90.3%, p = 0.0003). The presence of underlying carotid fibromuscular dysplasia was associated with migraine (35% vs 27%, p = 0.0175). There was not a significant association with carotid artery dissection and migraine. Current migraine frequency was less than monthly (58%), monthly (24%), weekly (16%), and daily (3%). Triptan use was reported in 32.5% of patients, and 17.5% used daily migraine prophylactic medications. Using the MIDAS to quantify disability related to migraine, 60.2% reported little or no disability, 14.4% mild, 12.7% moderate, and 12.7% severe. The mean MIDAS score was 9.9 (mild to moderate disability). Patients with SCAD had higher rates of depression and anxiety (28.2% vs 17.7% [ p = 0.0004] and 35.3% vs 26.7% [ p = 0.0099], respectively)., Conclusions: Migraines are common, frequent, and a source of disability in patients with SCAD. The association between female sex, anxiety, and depression may provide some insight for potential treatment modalities., Competing Interests: Declaration of conflicting interestsThe authors declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr Malissa Wood is a member of the Scientific Advisory Board of SCAD Alliance; she has no relationships with industry.

Background: Myocardial infarction secondary to spontaneous coronary artery dissection (SCAD) can be traumatic and potentially trigger posttraumatic stress disorder (PTSD). In a large, multicenter, registry-based cohort, we documented prevalence of lifetime and past-month SCAD-induced PTSD, as well as related treatment seeking, and examined a range of health-relevant correlates of SCAD-induced PTSD., Methods and Results: Patients with SCAD were enrolled in the iSCAD (International SCAD) Registry. At baseline, site investigators completed medical report forms, and patients reported demographics, medical/SCAD history, psychosocial factors (including SCAD-induced PTSD symptoms), health behaviors, and health status via online questionnaires. Of 1156 registry patients, 859 patients (93.9% women; mean age, 52.3 years) completed questionnaires querying SCAD-induced PTSD. Nearly 35% (n=298) of patients met diagnostic criteria for probable SCAD-induced PTSD in their lifetime, and 6.4% (n=55) met criteria for probable past-month PTSD. Of 811 patients ever reporting any SCAD-induced PTSD symptoms, 34.8% indicated seeking treatment for this distress. However, 46.0% of the 298 patients with lifetime probable SCAD-induced PTSD diagnoses reported never receiving trauma-related treatment. Younger age at first SCAD, fewer years since SCAD, being single, unemployed status, more lifetime trauma, and history of anxiety were associated with greater past-month PTSD symptom severity in multivariable regression models. Greater past-month SCAD-induced PTSD symptoms were associated with greater past-week sleep disturbance and worse past-month disease-specific health status when adjusting for various risk factors., Conclusions: Given the high prevalence of SCAD-induced PTSD symptoms, efforts to support screening for these symptoms and connecting patients experiencing distress with empirically supported treatments are critical next steps., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT04496687.

Background: A single, multitiered valve center designation has been proposed to publicly identify centers with expertise for all valve therapies. The correlation between transcatheter aortic valve replacement (TAVR) and mitral transcatheter edge-to-edge repair (MTEER) procedures is unknown., Objectives: The authors sought to examine the relationship between site-level volumes and outcomes for TAVR and MTEER. We further explored variability between sites for MTEER outcomes., Methods: Using the STS/ACC TVT (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy) national registry, TAVR and MTEER procedures at sites offering both therapies from 2013 to 2022 were examined. Sites were ranked into deciles of adjusted in-hospital and 30-day outcomes separately for TAVR and MTEER and compared. Stepwise, hierarchical multivariable models were constructed for MTEER outcomes, and the median OR was calculated., Results: Between 2013 and 2022, 384,394 TAVRs and 53,274 MTEERs (median annualized volumes: 93.6 and 18.8, respectively) were performed across 453 U.S. sites. Annualized TAVR and MTEER volumes were moderately correlated (r = 0.48; P < 0.001). After adjustment, 14.3% of sites had the same decile rank for TAVR and MTEER 30-day composite outcome, 50.6% were within 2 decile ranks; 35% had more discordant outcomes for the 2 procedures (P = 0.0005). For MTEER procedures, the median OR for the 30-day composite outcome was 1.57 (95% CI: 1.51-1.64), indicating a 57% variability in outcome by site., Conclusions: There is modest correlation between hospital-level volumes for TAVR and MTEER but low interprocedural correlation of outcomes. For similar patients, site-level variability for mortality/morbidity following MTEER was high. Factors influencing outcomes and "centers of excellence" as a whole may differ for TAVR and MTEER., Competing Interests: Funding Support and Author Disclosures Dr Kumbhani has received honoraria from the American College of Cardiology and the American Heart Association.

Background: Frailty associates with worse outcomes after transcatheter aortic valve replacement (TAVR). Sarcopenia underlies frailty, but the association between a comprehensive assessment of sarcopenia-muscle mass, strength, and performance-and outcomes after TAVR has not been examined., Methods: From a multicenter prospective registry of patients with symptomatic severe aortic stenosis undergoing TAVR, 445 who had a preprocedure computed tomography and clinical assessment of frailty were included. Cross-sectional muscle (psoas and paraspinal) areas were measured on computed tomography and indexed to height. Gait speed and handgrip strength were obtained, and patients were dichotomized into fast versus slow; strong versus weak; and normal versus low muscle mass. As measures of body composition, cross-sectional fat (subcutaneous and visceral) was measured and indexed to height., Results: The frequency of patients who were slow, weak, and had low muscle mass was 56%, 59%, and 42%, respectively. Among the 3 components of sarcopenia, only slower gait speed (muscle performance) was independently associated with increased post-TAVR mortality (adjusted hazard ratio, 1.12 per 0.1 m/s decrease [95% CI, 1.04-1.21]; P =0.004; adjusted hazard ratio, 1.38 per 1 SD decrease [95% CI, 1.11-1.72]; P =0.004). Meeting multiple sarcopenia criteria was not associated with higher mortality risk than fewer. Lower indexed visceral fat area (adjusted hazard ratio, 1.48 per 1 SD decrease [95% CI, 1.15-1.89]; P =0.002) was associated with mortality but indexed subcutaneous fat was not. Death occurred in 169 (38%) patients., Conclusions: Among patients with symptomatic severe aortic stenosis and comprehensive sarcopenia and body composition phenotyping, gait speed was the only sarcopenia measure associated with post-TAVR mortality. Lower visceral fat was also associated with increased risk pointing to an obesity paradox also observed in other patient populations. These findings reinforce the clinical utility of gait speed as a measure of risk and a potential target for adjunctive interventions alongside TAVR to optimize clinical outcomes., Competing Interests: Disclosures Dr Fearon receives institutional research support from Edwards, Abbott, Boston Scientific, and Medtronic; Dr Elmariah has received research grants from Edwards Lifesciences, Medtronic, and Abbott and consulting fees from Edwards Lifesciences; Dr Gillam is an advisor to Philips and Edwards Lifesciences and directs an imaging core laboratory with contracts with Edwards Lifesciences, Medtronic, and Abbott (no direct compensation); Dr Zajarias is a consult at Edwards Lifescience; Dr Welt formerly sat on the Medtronic Advisory Board; Dr Coylewright received research funding from Edwards LifeSciences; Dr Piana serves on the data safety monitoring boards for Abbott Medical and Baim Cardiovascular Research Institute; Dr Gupta receives research support from Imara Inc; and Dr Lindman has served on the scientific advisory board for Roche Diagnostics and has received research grants from Edwards Lifesciences and Roche Diagnostics.

There is a paucity of data regarding the contemporary temporal trends in the adoption of advanced pulmonary embolism (PE) therapies in the United States as well as the parallel trends in outcomes of patients with acute PE. Therefore, we queried the Nationwide Readmissions Database (years 2016-2020) to report the temporal trends in utilization of advanced PE therapies. Our final analysis included 920 770 hospitalizations with acute PE. We demonstrated an increase in the proportion of patients diagnosed with high-risk PE during the study years. Overall, there was an increase in the use of advanced PE therapies, which was mainly due to the increase in the utilization of systemic thrombolytics, and catheter-directed therapies. Also, extracorporeal membrane oxygenation cannulation showed an incremental increase over the study years. The use of inferior vena cava filter has declined, while the use of surgical embolectomy did not change during the study years. The use of advanced therapies has increased among urban teaching, but not among urban non-teaching hospitals. During the study years, there was no change in unadjusted or adjusted in-hospital mortality rates among patients with acute PE, while the 90-day unplanned readmission rate has declined., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

Background: There is a paucity of data regarding the comparative efficacy and safety of Mitral valve transcatheter edge-to-edge repair (MTEER) using the PASCAL or MitraClip systems for patients with mitral regurgitation (MR)., Methods: An electronic search was conducted for MEDLINE, COCHRANE, and EMBASE, through February 2023, for studies comparing the clinical outcomes of MTEER using PASCAL versus MitraClip systems among patients with severe MR. The primary study outcome was residual MR ≤ 2 at discharge. Data were pooled using a random-effects model., Results: The final analysis included six studies with a total of 1581 patients, with a weighted follow-up period of 3.5 months. Two studies only included patients with degenerative MR, while the remaining studies included both degenerative and functional MR. There was no significant difference in procedure duration between MTEER with the PASCAL or MitraClip systems. There was no difference in residual MR ≤ 2 at discharge (94.7% vs. 91.9%; odds ratio [OR]: 1.44; 95% confidence interval [CI]: 0.92-2.27) or residual MR ≤ 2 at the mid-term follow-up (94.6% vs. 91.0%, p = 0.05) among the PASCAL versus MitraClip systems. There was no difference between both groups in residual MR ≤ 1 at discharge (73.1% vs. 63.8%, p = 0.12), while there was greater incidence of residual MR ≤ 1 at midterm follow-up with the PASCAL system (71.3% vs. 56.2%, p < 0.001). There was no difference between the PASCAL and MitraClip MTEER systems in technical success (97.0% vs. 97.9%, p = 0.15), procedural success (89.1% vs. 87.1%, p = 0.78), single leaflet detachment (1.8% vs. 1.4%, p = 0.55), or all-cause mortality (3.6% vs. 4.6%, p = 0.71)., Conclusion: In this meta-analysis, we demonstrated comparable efficacy and safety between the PASCAL and MitraClip MTEER systems at short- and mid-term assessments. Randomized trials are warranted to evaluate the comparative long-term outcomes between both MTEER systems., (© 2023 Wiley Periodicals LLC.)

There is a paucity of data regarding the temporal trends and outcomes of transcatheter aortic valve implant (TAVI) among patients with a previous coronary artery bypass graft (CABG) surgery. We queried the Nationwide Readmissions Database (2016 to 2019) for hospitalized patients who underwent TAVI using the appropriate International Classification of Diseases, Tenth Revision procedural codes. A multivariable regression analysis was used to adjust for the patients' and hospitals' characteristics in comparing the study groups. The primary outcome was in-hospital mortality. The final analysis included 237,829 patients who underwent TAVI, of whom 42,671 (17.9%) had a previous CABG. During the study period, there was a decrease in the proportion of patients with previous CABG who underwent TAVI (21.0% in 2016 vs 15.5% in 2019, p trend  = 0.01), although there was no change in their in-hospital mortality rate (1.08% in 2016 vs 1.25% in 2019, p trend  = 0.43). Patients with a previous CABG were younger and less likely to be women than those without a previous CABG. TAVI among those with a previous CABG was associated with lower in-hospital mortality (adjusted odds ratio [aOR] 0.79, 95% confidence interval [CI] 0.69 to 0.91), similar rate of ischemic stroke (aOR 0.81, 95% CI 0.71 to 0.93) and permanent pacemaker implant (aOR 1.00, 95% CI 0.93 to 1.05). Patients with a previous CABG had a lower all-cause 90-day readmission (odds ratio 0.95, 95% CI 0.94 to 1.06) but higher readmission for transient ischemic attack. Among those with a previous CABG, female gender and chronic kidney disease stage ≥3 were independently associated with a higher in-hospital mortality, whereas obesity was associated with a lower in-hospital mortality. In conclusion, there was a decrease in the proportion of patients with a previous CABG among those who underwent TAVI. TAVI among those with a previous CABG was not associated with increased in-hospital adverse events or 90-day all-cause readmissions., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Inc.

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.

Background: Depression and cognitive dysfunction (CD) are not routinely screened for in patients before transcatheter aortic valve replacement (TAVR) and their association with postprocedural outcomes is poorly understood. The objectives of this study are to determine the prevalence of depression and CD in patients with aortic stenosis undergoing TAVR and evaluate their association with mortality and quality of life., Methods: We analyzed a prospective, multicenter TAVR registry that systematically screened patients for preexisting depression and CD with the Patient Health Questionnaire-2 and Mini-Cog, respectively. The associations with mortality were assessed with Cox proportional hazard models and quality of life (Kansas City Cardiomyopathy Questionnaire and EuroQol visual analogue scale) were evaluated using multivariable ordinal regression models., Results: A total of 884 patients were included; median follow-up was 2.88 years (interquartile range=1.2-3.7). At baseline, depression was observed in 19.6% and CD in 31.8%. In separate models, after adjustment, depression (HR, 1.45 [95% CI, 1.13-1.86]; P <0.01) and CD (HR, 1.27 [95% CI, 1.02-1.59]; P =0.04) were each associated with increased mortality. Combining depression and CD into a single model, mortality was greatest among those with both depression and CD (n=62; HR, 2.06 [CI, 1.44-2.96]; P <0.01). After adjustment, depression was associated with 6.6 (0.3-13.6) points lower on the Kansas City Cardiomyopathy Questionnaire 1-year post-TAVR and 6.7 (0.5-12.7) points lower on the EuroQol visual analogue scale. CD was only associated with lower EuroQol visual analogue scale., Conclusions: Depression and CD are common in patients that undergo TAVR and are associated with increased mortality and worse quality of life. Depression may be a modifiable therapeutic target to improve outcomes after TAVR., Competing Interests: Disclosures Dr Fearon receives institutional research support from Edwards, Abbott, Boston Scientific, and Medtronic.

Background Studies in mice and small patient subsets implicate metabolic dysfunction in cardiac remodeling in aortic stenosis, but no large comprehensive studies of human metabolism in aortic stenosis with long-term follow-up and characterization currently exist. Methods and Results Within a multicenter prospective cohort study, we used principal components analysis to summarize 12 echocardiographic measures of left ventricular structure and function pre-transcatheter aortic valve implantation in 519 subjects (derivation). We used least absolute shrinkage and selection operator regression across 221 metabolites to define metabolic signatures for each structural pattern and measured their relation to death and multimorbidity in the original cohort and up to 2 validation cohorts (N=543 for overall validation). In the derivation cohort (519 individuals; median age, 84 years, 45% women, 95% White individuals), we identified 3 axes of left ventricular remodeling, broadly specifying systolic function, diastolic function, and chamber volumes. Metabolite signatures of each axis specified both known and novel pathways in hypertrophy and cardiac dysfunction. Over a median of 3.1 years (205 deaths), a metabolite score for diastolic function was independently associated with post-transcatheter aortic valve implantation death (adjusted hazard ratio per 1 SD increase in score, 1.54 [95% CI, 1.25-1.90]; P <0.001), with similar effects in each validation cohort. This metabolite score of diastolic function was simultaneously associated with measures of multimorbidity, suggesting a metabolic link between cardiac and noncardiac state in aortic stenosis. Conclusions Metabolite profiles of cardiac structure identify individuals at high risk for death following transcatheter aortic valve implantation and concurrent multimorbidity. These results call for efforts to address potentially reversible metabolic biology associated with risk to optimize post-transcatheter aortic valve implantation recovery, rehabilitation, and survival.

Background In-stent restenosis (ISR) is commonly encountered even in the era of contemporary percutaneous coronary intervention (PCI). There is a paucity of data on the comparative outcomes of PCI for ISR lesions versus de novo lesions. Methods and Results An electronic search was conducted for MEDLINE, Cochrane, and Embase through August 2022 for studies comparing the clinical outcomes after PCI for ISR versus de novo lesions. The primary outcome was major adverse cardiac events. Data were pooled using a random-effects model. The final analysis included 12 studies, with a total of 708 391 patients, of whom 71 353 (10.3%) underwent PCI for ISR. The weighted follow-up duration was 29.1 months. Compared with de novo lesions, PCI for ISR was associated with a higher incidence of major adverse cardiac events (odds ratio [OR], 1.31 [95% CI, 1.18-1.46]). There was no difference on a subgroup analysis of chronic total occlusion lesions versus none ( P interaction =0.69). PCI for ISR was associated with a higher incidence of all-cause mortality (OR, 1.03 [95% CI, 1.02-1.04]), myocardial infarction (OR, 1.20 [95% CI, 1.11-1.29]), target vessel revascularization (OR, 1.42 [95% CI, 1.29-1.55]), and stent thrombosis (OR, 1.44 [95% CI, 1.11-1.87]), but no difference in cardiovascular mortality (OR, 1.04 [95% CI, 0.90-1.20]). Conclusions PCI for ISR is associated with higher incidence of adverse cardiac events compared with PCI for de novo lesions. Future efforts should be directed toward prevention of ISR and exploring novel treatment strategies for ISR lesions.

Background: Randomized clinical trials (RCTs) evaluating the role of intravenous (IV) iron administration in patients with heart failure (HF) and iron deficiency (ID) have yielded inconsistent results., Methods: Electronic search of MEDLINE, EMBASE and OVID databases was performed until November 2022 for RCTs that evaluated the role of IV iron administration in patients with HF and ID. The main study outcomes were the composite of HF hospitalization or cardiovascular mortality, and individual outcome of HF hospitalization. Summary estimates were evaluated using random effects model., Results: The final analysis included 12 RCTs with 3,492 patients (1,831 patients in the IV iron group and 1,661 patients in the control group). The mean follow-up was 8.3 months. IV iron was associated with a lower incidence in the composite of HF hospitalization or cardiovascular mortality (31.9% vs. 45.3%; relative risk [RR] 0.72; 95% confidence interval [CI] 0.59-0.88) and individual outcome of HF hospitalization (28.4% vs. 42.2; RR 0.69; 95% CI 0.57-0.85). There was no significant difference between both groups in cardiovascular mortality (RR 0.88; 95% CI 0.75-1.04) and all-cause mortality (RR 0.95; 95% CI 0.83-1.09). IV iron was associated with lower New York Heart Association class and higher left ventricular ejection fraction (LVEF). Meta-regression analyses showed no effect modification for the main outcomes based on age, hemoglobin level, ferritin level or LVEF., Conclusion: Among patients with HF and ID, IV iron administration was associated with reduction in the composite of HF hospitalization or cardiovascular mortality and driven by a reduction in HF hospitalization., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Importance: Professional societies and the Centers for Medicare & Medicaid Services suggest volume thresholds to ensure quality in transcatheter aortic valve implantation (TAVI)., Objective: To model the association of volume thresholds vs spoke-and-hub implementation of outcome thresholds with TAVI outcomes and geographic access., Design, Setting, and Participants: This cohort study included patients who enrolled in the US Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy registry. Site volume and outcomes were determined from a baseline cohort of adults undergoing TAVI between July 1, 2017, and June 30, 2020., Exposures: Within each hospital referral region, TAVI sites were categorized by volume (<50 or ≥50 TAVIs per year) and separately by risk-adjusted outcome on the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy 30-day TAVI composite during the baseline period (July 2017 to June 2020). Outcomes of patients undergoing TAVIs from July 1, 2020, to March 31, 2022, were then modeled as though the patients had been treated at (1) the nearest higher volume (≥50 TAVIs per year) or (2) the best outcome site within the hospital referral region., Main Outcomes and Measures: The primary outcome was the absolute difference in events between the adjusted observed and modeled 30-day composite of death, stroke, major bleeding, stage III acute kidney injury, and paravalvular leak. Data are presented as the number of events reduced under the above scenarios with 95% bayesian credible intervals (CrIs) and median (IQR) driving distance., Results: The overall cohort included 166 248 patients with a mean (SD) age of 79.5 (8.6) years; 74 699 (47.3%) were female and 6657 (4.2%) were Black; 158 025 (95%) were treated in higher-volume sites (≥50 TAVIs) and 75 088 (45%) were treated in best-outcome sites. Modeling a volume threshold, there was no significant reduction in estimated adverse events (-34; 95% CrI, -75 to 8), while the median (IQR) driving time from the existing site to the alternate site was 22 (15-66) minutes. Transitioning care to the best outcome site in a hospital referral region resulted in an estimated 1261 fewer adverse outcomes (95% CrI, 1013-1500), while the median (IQR) driving time from the original site to the best site was 23 (15-41) minutes. Directionally similar findings were observed for Black individuals, Hispanic individuals, and individuals from rural areas., Conclusions and Relevance: In this study, compared with the current system of care, a modeled outcome-based spoke-and-hub paradigm of TAVI care improved national outcomes to a greater extent than a simulated volume threshold, at the cost of increased driving time. To improve quality while maintaining geographic access, efforts should focus on reducing site variation in outcomes.

Background: The contemporary measures of hospital performance for heart failure hospitalization and 30-day risk-standardized readmission rate (RSRR) and risk-standardized mortality rate (RSMR) are estimated using the same risk adjustment model and overall event rate for all patients. Thus, these measures are mainly driven by the care quality and outcomes for the majority racial and ethnic group, and may not adequately represent the hospital performance for patients of Black and other races., Methods: Fee-for-service Medicare beneficiaries from January 2014 to December 2019 hospitalized with heart failure were identified. Hospital-level 30-day RSRR and RSMR were estimated using the traditional race-agnostic models and the race-specific approach. The composite race-specific performance metric was calculated as the average of the RSRR/RMSR measures derived separately for each race and ethnicity group. Correlation and concordance in hospital performance for all patients and patients of Black and other races were assessed using the composite race-specific and race-agnostic metrics., Results: The study included 1 903 232 patients (75.7% White [n=1 439 958]; 14.5% Black [n=276 684]; and 9.8% other races [n=186 590]) with heart failure from 1860 hospitals. There was a modest correlation between hospital-level 30-day performance metrics for patients of White versus Black race (Pearson correlation coefficient: RSRR=0.42; RSMR=0.26). Compared with the race-agnostic RSRR and RSMR, composite race-specific metrics for all patients demonstrated stronger correlation with RSRR (correlation coefficient: 0.60 versus 0.74) and RSMR (correlation coefficient: 0.44 versus 0.51) for Black patients. Concordance in hospital performance for all patients and patients of Black race was also higher with race-specific (versus race-agnostic) metrics (RSRR=64% versus 53% concordantly high-performing; 61% versus 51% concordantly low-performing). Race-specific RSRR and RSMR metrics (versus race-agnostic) led to reclassification in performance ranking of 35.8% and 39.2% of hospitals, respectively, with better 30-day and 1-year outcomes for patients of all race groups at hospitals reclassified as high-performing., Conclusions: Among patients hospitalized with heart failure, race-specific 30-day RSMR and RSRR are more equitable in representing hospital performance for patients of Black and other races.

Background: Cardiac amyloidosis can coexist in patients with severe aortic stenosis. There are limited outcomes data on whether this impacts the risk of transcatheter aortic valve replacement (TAVR)., Objectives: The authors aimed to investigate the effect of amyloidosis on outcomes of TAVR., Methods: We used the Nationwide Readmissions Database to identify hospitalizations for TAVR between 2016 and 2019. The presence of a diagnosis of amyloidosis was identified. Propensity score-weighted regression analysis was used to identify the association of amyloidosis with in-hospital mortality, acute ischemic stroke, and 30-day readmission rate after TAVR., Results: We identified 245,020 hospitalizations for TAVR, including 273 in patients with amyloidosis. The mean age was 79.4 ± 8.4 years. There was no difference in in-hospital mortality or 30-day readmission rate in patients with and without amyloidosis (1.8% vs 1.5%, P  = 0.622; and 12.9% vs 12.5%, P  = 0.858; respectively). However, there was a higher rate of acute ischemic stroke in patients with amyloidosis (6.2% vs 1.8%, P  < 0.001). Propensity score-weighted logistic regression analysis showed the presence of amyloidosis was associated with greater odds of acute ischemic stroke (odds ratio: 3.08, 95% CI: 1.41-6.71, P  = 0.005), but no difference in mortality (odds ratio: 0.79, 95% CI: 0.28-2.27, P  = 0.666) or 30-day readmission rate after TAVR (HR: 0.72, 95% CI: 0.41-1.25, P  = 0.241)., Conclusions: This analysis suggests amyloidosis may be associated with a higher thromboembolic risk after TAVR that merits further investigation., Competing Interests: Dr Grodin is a consultant for Pfizer, Alnylam, Eidos and Sarepta; and has received research support from Eidos and the Texas Health Resources Clinical Scholarship.

There was no difference in in-hospital mortality or 30-day readmission rates. TRANSLATIONAL OUTLOOK: The observed higher risk of stroke highlights the potential for greater thromboembolic risk after TAVR that deserves to be further studied., (© 2023 The Authors.)

Background: Assessing hospital performance for cardiac surgery necessitates consistent and valid care quality metrics. The association of hospital-level risk-standardized home time for cardiac surgeries with other performance metrics such as mortality rate, readmission rate, and annual surgical volume has not been evaluated previously., Methods: The study included Medicare beneficiaries who underwent isolated or concomitant coronary artery bypass graft, aortic valve, or mitral valve surgery from January 1, 2013, to October 1, 2019. Hospital-level performance metrics of annual surgical volume, 90-day risk-standardized mortality rate, 90-day risk-standardized readmission rate, and 90-day risk-standardized home time were estimated starting from the day of surgery using generalized linear mixed models with a random intercept for the hospital. Correlations between the performance metrics were assessed using the Pearson correlation coefficient. Patient-level clinical outcomes were also compared across hospital quartiles by 90-day risk-standardized home time. Last, the temporal stability of performance metrics for each hospital during the study years was also assessed., Results: Overall, 919 698 patients (age 74.2±5.8 years, 32% women) were included from 1179 hospitals. Median 90-day risk-standardized home time was 71.2 days (25th-75th percentile, 66.5-75.6), 90-day risk-standardized readmission rate was 26.0% (19.5%-35.7%), and 90-day risk-standardized mortality rate was 6.0% (4.0%-8.8%). Across 90-day home time quartiles, a graded decline was observed in the rates of in-hospital, 90-day, and 1-year mortality, and 90-day and 1-year readmission. Ninety-day home time had a significant positive correlation with annual surgical volume ( r =0.31; P <0.001) and inverse correlation with 90-day risk-standardized readmission rate ( r =-0.40; P  <0.001) and 90-day risk-standardized mortality rate ( r =-0.60; P  <0.001). Use of 90-day home time as a performance metric resulted in a meaningful reclassification in performance ranking of 22.8% hospitals compared with annual surgical volume, 11.6% compared with 90-day risk-standardized mortality rate, and 19.9% compared with 90-day risk-standardized readmission rate. Across the 7 years of the study period, 90-day home time demonstrated the most temporal stability of the hospital performance metrics., Conclusions: Ninety-day risk-standardized home time is a feasible, comprehensive, patient-centered metric to assess hospital-level performance in cardiac surgery with greater temporal stability than mortality and readmission measures.

Background Global longitudinal strain (GLS) is a sensitive measure of left ventricular function and a risk marker in severe aortic stenosis. We sought to determine whether biomarkers of cardiac damage (cardiac troponin) and stress (NT-proBNP [N-terminal pro-B-type natriuretic peptide]) could complement GLS to identify patients with severe aortic stenosis at highest risk. Methods and Results From a multicenter prospective cohort of patients with symptomatic severe aortic stenosis who underwent transcatheter aortic valve implantation, we measured absolute GLS (aGLS), cardiac troponin, and NT-proBNP at baseline in 499 patients. Left ventricular ejection fraction <50% was observed in 19% and impaired GLS (aGLS <15%) in 38%. Elevations in cardiac troponin and NT-proBNP were present in 79% and 89% of those with impaired GLS, respectively, as compared with 63% and 60% of those with normal GLS, respectively ( P <0.001 for each). aGLS <15% was associated with increased mortality in univariable analysis ( P =0.009), but, in a model with both biomarkers, aGLS, and clinical covariates included, aGLS was not associated with mortality; elevation in each biomarker was associated with an increased hazard of mortality (adjusted hazard ratio, >2; P ≤0.002 for each) when the other biomarker was elevated, but not when the other biomarker was normal (interaction P =0.015). Conclusions Among patients with symptomatic severe aortic stenosis undergoing transcatheter aortic valve implantation, elevations in circulating cardiac troponin and NT-proBNP are more common as GLS worsens. Biomarkers of cardiac damage and stress are independently associated with mortality after transcatheter aortic valve implantation, whereas GLS is not. These findings may have implications for risk stratification of asymptomatic patients to determine optimal timing of valve replacement.

A 60-year-old female underwent a left ventricular assist device implantation during which a 1-mm Gore-Tex sheet was used to cover the device and outflow graft to prevent future sternal re-entry injury. Seven years later, she developed low-flow alarms with a pattern of gradual decline in flow and power suggestive of outflow graft obstruction. After a discussion with the multidisciplinary team, percutaneous stenting of the outflow graft was pursued.

Background Left ventricular hypertrophy (LVH) is associated with increased mortality risk and rehospitalization after transcatheter aortic valve replacement among those with severe aortic stenosis. Whether cardiac troponin (cTnT) and NT-proBNP (N-terminal pro-B-type natriuretic peptide) risk stratify patients with aortic stenosis and without LVH is unknown. Methods and Results In a multicenter prospective registry of 923 patients with severe aortic stenosis undergoing transcatheter aortic valve replacement, we included 674 with core-laboratory-measured LV mass index, cTnT, and NT-proBNP. LVH was defined by sex-specific guideline cut-offs and elevated biomarker levels were based on age and sex cut-offs. Adjusted Cox proportional hazards models evaluated associations between LVH and biomarkers and all-cause death out to 5 years. Elevated cTnT and NT-proBNP were present in 82% and 86% of patients with moderate/severe LVH, respectively, as compared with 66% and 69% of patients with no/mild LVH, respectively ( P <0.001 for each). After adjustment, compared with no/mild LVH, moderate/severe LVH was associated with an increased hazard of mortality (adjusted hazard ratio [aHR], 1.34; 95% CI 1.01-1.77, P =0.043). cTnT and NT-proBNP each risk stratified patients with moderate/severe LVH ( P <0.05). In a model with both biomarkers and LVH included, elevated cTnT (aHR, 2.08; 95% CI 1.45-3.00, P <0.001) and elevated NT-proBNP (aHR, 1.46; 95% CI 1.00-2.11, P =0.049) were each associated with increased mortality risk, whereas moderate/severe LVH was not ( P =0.15). Conclusions Elevations in circulating cTnT and NT-proBNP are more common as LVH becomes more pronounced but are also observed in those with no/minimal LVH. As measures of maladaptive remodeling and cardiac injury, cTnT and NT-proBNP predict post-transcatheter aortic valve replacement mortality better than LV mass index. These findings may have important implications for risk stratification and treatment of patients with aortic stenosis.

Background: Patient-centric measures of hospital performance for transcatheter aortic valve replacement (TAVR) are needed., Objectives: This study evaluated 30-day, risk-adjusted home time as a hospital performance metric for patients who underwent TAVR., Methods: This study identified 160,792 Medicare beneficiaries who underwent elective TAVR from 2015 to 2019. Home time was calculated for each patient as the number of days alive and spent outside the hospital, skilled nursing facility (SNF), and long-term acute care facility for 30 days after the TAVR procedure date. Correlations between risk-adjusted, 30-day home time and other metrics (30-day, risk-adjusted readmission rate [RSRR], 30-day, risk-adjusted mortality rate [RSMR], and annual TAVR volume) were estimated using Pearson's correlation. Meaningful upward or downward reclassification (≥2 quartile ranks) in hospital performance based on quartiles of risk-adjusted, 30-day home time compared with quartiles of other measures were assessed., Results: Median risk-adjusted, 30-day home time was 27.4 days (interquartile range [IQR]: 26.3-28.5 days). The largest proportion of days lost from 30-day home time was hospital stay after TAVR and SNF stay. An inverse correlation was observed between hospital-level, risk-adjusted, 30-day home time and 30-day RSRR (r = -0.465; P < 0.001) and 30-day RSMR (r = -0.3996; P < 0.001). The use of the 30-day, risk-adjusted home time was associated with reclassification in hospital performance rank hospitals compared with other metrics (9.1% up-classified, 11.2% down-classified vs RSRR; 9.1% up-classified, 10.3% down-classified vs RSMR; and 20.1% up-classified, 19.3% down-classified vs annual TAVR volume)., Conclusions: Risk-adjusted, 30-day home time represents a novel patient-centered performance metric for TAVR hospitals that may provide a complimentary assessment to currently used metrics., Competing Interests: Funding Support and Author Disclosures Dr Mack has received consulting fees from Gore; has served as a trial co-primary investigator for Edwards Lifesciences and Abbott; and has served as a study chair for Medtronic.
