Article Synopsis
  • Research indicates that metabolic dysfunction plays a role in heart changes due to aortic stenosis, but a significant study on human metabolism hasn't been done yet.
  • In a study involving 519 patients, researchers examined 12 heart function metrics before valve implantation and identified three patterns of heart remodeling, linking these to specific metabolic profiles.
  • A distinctive metabolite score for heart function was found to predict higher death rates post-surgery and was related to overall health issues, emphasizing the need to explore metabolic factors to improve patient outcomes after transcatheter aortic valve placement.

Background Endovascular intervention of femoropopliteal chronic total occlusions (CTOs) is technically more complex. However, there is lack of comparative analysis between CTO and non-CTO femoropopliteal interventions. Methods and Results We report procedural details and outcomes of patients treated for femoropopliteal CTO and non-CTO lesions in the XLPAD (Excellence in Peripheral Artery Disease) registry (NCT01904851) between 2006 and 2019.

Background Premature discontinuation of P2Y12 inhibitor therapy has been associated with adverse cardiac events, which might be preventable by improving medication persistence. Current risk models have limited ability to predict patients at risk of P2Y12 inhibitor nonpersistence. Methods and Results ARTEMIS (Affordability and Real-World Antiplatelet Treatment Effectiveness after Myocardial Infarction Study) was a randomized, controlled trial testing the impact of a copayment assistance intervention on P2Y12 inhibitor persistence and outcomes.

Article Synopsis
  • Current clinical recommendations for young athletes with cardiovascular conditions are mainly based on expert consensus, lacking robust data on outcomes.
  • The ORCCA study aims to monitor the health and decision-making of competitive athletes aged 18-35 with cardiovascular issues over a 5-year period, focusing on sports participation and psychosocial well-being.
  • This research seeks to provide data that can help shape future guidelines on sports participation for athletes at risk of serious cardiovascular events.

Background Diabetes and hypertension have been associated with adverse left ventricular (LV) remodeling. While they often occur concurrently, their individual effects are understudied. We aimed to assess the independent effects of diabetes and hypertension on LV remodeling in Black adults.

Background Advanced kidney disease is often a relative contraindication to left ventricular assist device (LVAD) implantation because of concerns for poor outcomes including worsening kidney disease. Data are lacking on long-term changes and sex-based differences in estimated glomerular filtration rate (eGFR), with published data limited by potential bias introduced by the competing risks of death and heart transplantation. Methods and Results We conducted a longitudinal analysis of 288 adults receiving durable continuous-flow LVADs from January 2010 to December 2017 at a single center.

Background Among patients with nonvalvular atrial fibrillation (AF) and an elevated stroke risk, guidelines recommend direct oral anticoagulants (DOACs) over warfarin for stroke prevention. Changes in DOAC use over the past decade have not been well described. Methods and Results We evaluated trends in use of DOACs and warfarin from 2011 to 2020 among adults with AF and a CHADS-VASc score ≥2 based on electronic health record data from 88 health systems in the United States contributing to Cerner Real World Data.

Background Persistence to P2Y12 inhibitors after myocardial infarction (MI) remains low. Out-of-pocket cost is cited as a factor affecting medication compliance. We examined whether a copayment intervention affected 1-year persistence to P2Y12 inhibitors and clinical outcomes.

Article Synopsis
  • Global longitudinal strain (GLS) serves as a measure of left ventricular function, and the study aimed to see if cardiac damage (troponin) and stress (NT-proBNP) biomarkers can enhance GLS effectiveness in identifying high-risk patients with severe aortic stenosis.
  • In a study involving 499 patients who underwent transcatheter aortic valve implantation, it was found that patients with impaired GLS had higher levels of cardiac troponin and NT-proBNP compared to those with normal GLS.
  • The analysis revealed that while lower GLS indicated increased mortality likelihood, the biomarkers of cardiac damage and stress were independently linked to mortality risk, suggesting that these biomarkers may be more reliable for assessing patient risk and timing for valve replacement.

Background Patients with congenital heart disease (CHD) are at risk for the development of low cardiac output and other physiologic derangements, which could be detected early through continuous stroke volume (SV) measurement. Unfortunately, existing SV measurement methods are limited in the clinic because of their invasiveness (eg, thermodilution), location (eg, cardiac magnetic resonance imaging), or unreliability (eg, bioimpedance). Multimodal wearable sensing, leveraging the seismocardiogram, a sternal vibration signal associated with cardiomechanical activity, offers a means to monitoring SV conveniently, affordably, and continuously.

Background The AHA Registry (American Heart Association COVID-19 Cardiovascular Disease Registry) captures detailed information on hospitalized patients with COVID-19. The registry, however, does not capture information on social determinants of health or long-term outcomes. Here we describe the linkage of the AHA Registry with external data sources, including fee-for-service (FFS) Medicare claims, to fill these gaps and assess the representativeness of linked registry patients to the broader Medicare FFS population hospitalized with COVID-19.

Background We showed that Beclin-1-dependent autophagy protects the heart in young and adult mice that underwent endotoxemia. Herein, we compared the potential therapeutic effects of Beclin-1 activating peptide, TB-peptide, on endotoxemia-induced cardiac outcomes in young adult and aged mice. We further evaluated lipopolysaccharide (lipopolysaccharide)-induced and TB-peptide treatment-mediated alterations in myocardial metabolism.

Article Synopsis
  • The WATCH-DM and TRS-HF risk scores were created to predict heart failure risk specifically in individuals with type 2 diabetes, with WATCH-DM focusing on predicting new heart failure events and TRS-HF on hospitalizations due to heart failure.
  • In a study analyzing two clinical trial cohorts (TECOS and Look AHEAD) and a health record cohort, both risk scores demonstrated similar performance in predicting five-year heart failure risk, particularly in the Look AHEAD cohort.
  • However, there were significant differences in performance, with lower predictive accuracy found in the TECOS cohort, where both scores underpredicted the risk of heart failure events.

Benzylic/allylic alcohols are converted site-selective C(sp)-C(sp) cleavage to value-added nitrogenous motifs, , anilines and/or nitriles as well as N-heterocycles, utilizing commercial hydroxylamine--sulfonic acid (HOSA) and EtN in an operationally simple, one-pot process. Notably, cyclic benzylic/allylic alcohols undergo bis-functionalization with attendant increases in architectural complexity and step-economy.

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.

Background Assessing the risk of serious adverse events (SAEs) during hypertension treatment is important for understanding the benefit-harm trade-offs of lower blood pressure goals. It is unknown whether high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) provide information about SAEs. Methods and Results In SPRINT (Systolic Blood Pressure Intervention Trial), hs-cTnT and NT-proBNP were measured at baseline in 8828 (94.
