Characteristics of High-Performing Hospitals in Cardiogenic Shock Following Acute Myocardial Infarction.

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.

Posttraumatic Stress Disorder After Spontaneous Coronary Artery Dissection: A Report of the International Spontaneous Coronary Artery Dissection Registry.

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.

National Variation in Hospital MTEER Outcomes and Correlation With TAVR Outcomes: STS/ACC TVT Registry Analysis.

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.

Associations of Sarcopenia and Body Composition Measures With Mortality After Transcatheter Aortic Valve Replacement.

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.

Temporal trends in the utilization of advanced therapies among patients with acute pulmonary embolism: insights from a national database.

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.

Outcomes of Transcatheter Aortic Valve Implant Among Patients With A Previous Coronary Artery Bypass Graft: A Nationwide Analysis.

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, ptrend = 0.01), although there was no change in their in-hospital mortality rate (1.08% in 2016 vs 1.25% in 2019, ptrend = 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.

Association of Depression and Cognitive Dysfunction With Patient-Centered Outcomes After Transcatheter Aortic Valve Replacement.

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.

Transcatheter edge-to-edge repair for mitral regurgitation using PASCAL or MitraClip.

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.
