ImportanceTranscatheter aortic valve replacement (TAVR) is an established treatment option for many patients with severe symptomatic aortic stenosis; however, debris dislodged during the procedure can cause embolic stroke. The Sentinel cerebral embolic protection (CEP) device is approved for capture and removal of embolic material during TAVR but its efficacy has been debated.ObjectiveTo explore regional differences in the association of CEP utilization with stroke outcomes in patients undergoing TAVR.Design, Setting, and ParticipantsThis post hoc analysis of a prospective, postmarket, randomized clinical trial evaluating TAVR performed with or without the CEP took place at 51 hospitals in the US, Europe, and Australia from February 2020 to January 2022. Patients with symptomatic aortic stenosis treated with transfemoral TAVR were included. Randomization was stratified according to center, operative risk, and intended TAVR valve type. Patients were excluded if the left common carotid or brachiocephalic artery had greater than 70% stenosis or if the anatomy precluded placement of the CEP device. Data for this post hoc study were analyzed from August to October 2024.InterventionTAVR with or without CEP.Main Outcomes and MeasuresThe primary end point was the rate of all stroke events at hospital discharge or 72 hours post-TAVR, whichever came first. Neurological examinations were performed at baseline and postprocedure to identify stroke, disabling stroke, and other neurological outcomes.ResultsThe Stroke Protection With Sentinel During Transcatheter Aortic Valve Replacement (PROTECTED TAVR) trial enrolled and randomized 3000 patients (1803 [60.1%] male; mean [SD] age, 78.9 [7.8] years): 1833 in the US cohort (TAVR alone: 919, TAVR with CEP: 914) and 1167 patients in the outside the US (OUS) cohort (TAVR alone: 580, TAVR with CEP: 587). Patients in the US cohort were younger, more predominantly male, had a lower prevalence of atrial fibrillation, and had a higher prevalence of bicuspid aortic valve, diabetes, and peripheral vascular disease compared with the OUS cohort. In the main trial, the incidence of stroke within 72 hours after TAVR or before discharge did not differ significantly between the CEP group and the control group, and there was no interaction by geographic region. In this post hoc analysis, patients treated with CEP in the US cohort exhibited a 50% relative risk reduction for overall stroke and a 73% relative risk reduction for disabling stroke compared to TAVR alone; a treatment effect on stroke risk reduction was not observed in the OUS cohort.Conclusion and RelevanceThe PROTECTED TAVR trial could not show that the use of CEP had a significant effect on the incidence of periprocedural stroke during TAVR. Although there was no significant interaction by geographic region, this exploratory post hoc analysis suggests a trend toward greater stroke reduction in the US cohort but not in the OUS cohort.

ImportanceThe clinical utility of polygenic risk scores (PRS) for blood pressure (BP) response to antihypertensive treatment (AHT) has not been elucidated.ObjectiveTo investigate the ability of a systolic BP (SBP) PRS to predict AHT response and apparent treatment-resistant hypertension (aTRH).Design, Setting, and ParticipantsThe Genetics of Hypertension Associated Treatments (GenHAT) study was an ancillary pharmacogenomic study to the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). ALLHAT, which enrolled participants aged 55 years or older with hypertension (HTN) starting in February 1994, completed follow-up in March 2002. The current study was conducted from a subset of Black GenHAT participants randomized to the treatment groups of either chlorthalidone (n = 3745) or lisinopril (n = 2294), with genetic data available from a prior genetic association study. The current study's objective was to examine the association of the SBP PRS to AHT response over 6 months, as well as to examine the predictive accuracy of the SBP PRS with aTRH. The current analysis took place in February 2023, with additional analyses conducted in July 2024.ExposureAn SBP PRS (comprising 1 084 157 genetic variants) stratified as quintiles and per SD.Main Outcomes and MeasuresThe primary outcome was change in SBP (ΔSBP) and diastolic BP (ΔDBP) over 6 months. aTRH was defined as the use of 3 AHTs with uncontrolled HTN at year 3 of follow-up or taking 4 or more AHTs at year 3 of follow-up, regardless of BP. Baseline demographics were compared across PRS quintiles using Kruskal-Wallis or χ2 tests as appropriate. The least-square means of BP response were calculated through multivariable adjusted linear regression, and multivariable adjusted logistic regression was used to calculate the odds ratios and 95% confidence intervals for aTRH.ResultsAmong 3745 Black GenHAT participants randomized to chlorthalidone treatment, median (IQR) participant age was 65 (60-71) years, and 2064 participants (55.1%) were female. Each increasing quintile of the SBP PRS from 1 to 5 was associated with a reduced BP response to treatment over 6 months. Participants in the lowest quintile experienced a mean ΔSBP of -10.01 mm Hg (95% CI, -11.11 to -8.90) compared to -6.57 mm Hg (95% CI, -7.67 to -5.48) for participants in the median quintile. No associations were observed between the SBP PRS and BP response to lisinopril. Participants in the highest PRS quintile had 67% higher odds of aTRH compared to those in the median quintile (odds ratio, 1.67; 95% CI, 1.19-2.36). These associations were independently validated.Conclusions and RelevanceIn this genetic association study, Black individuals with HTN at a lower genetic risk of elevated BP experienced an approximately 3.5 mm Hg-greater response to chlorthalidone compared with those at an intermediate genetic risk of elevated BP. SBP PRS may also identify individuals with HTN harboring a higher risk of treatment-res

ImportanceAlthough transcatheter aortic valve replacement (TAVR) outcomes in the US have improved substantially since 2011, it is unknown whether these trends have continued since 2019.ObjectiveTo examine changes in risk-adjusted TAVR outcomes from 2019 to 2022 and to examine any noteworthy trends over time.Design, Setting, and ParticipantsThis cohort study examined data from patients with severe aortic stenosis treated with TAVR at 786 US hospitals between January 1, 2019, and March 31, 2022, included in the Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) Transcatheter Valve Therapies (TVT) Registry.ExposurePatients who underwent TAVR.Main Outcomes and MeasuresThe primary outcome was 30-day mortality, and the secondary outcomes were in-hospital mortality and 30-day composite adverse events. To understand factors explaining these trends, a series of logistic regression models was constructed for each outcome, with time as the primary explanatory variable. After adjusting for changing patent characteristics and procedural factors, a series of exploratory analyses was performed to examine the extent to which these findings could be explained by several plausible hypotheses.ResultsThis study's analytic cohort included a total of 210 495 patients. Median (IQR) patient age was 79 (73-85) years, and 91 313 patients (43.4%) were female. Median (IQR) STS predicted risk of mortality (PROM) was 3.3% (2.0%-5.3%). There were no significant changes in unadjusted 30-day mortality from quarter 1 of 2019 (2.4%) to the end of quarter 1 of 2022 (2.2%) (P for trend = .10), with an unadjusted odds ratio (OR) for time of 0.98 per year (95% CI, 0.94-1.01). After adjusting for patient characteristics, the OR increased to 1.05 per year (95% CI, 1.02-1.08), which increased further after adjusting for procedural characteristics to 1.09 per year (95% CI, 1.05-1.13). In exploratory analyses, there were no meaningful changes in the adjusted odds of death after excluding sites that entered the STS/ACC TVT Registry in 2019 or later (OR, 1.09; 95% CI, 1.05-1.13), low-volume sites (OR, 1.09; 95% CI, 1.06-1.13), low-risk patients (OR, 1.11; 95% CI, 1.07-1.15), patients with a bicuspid aortic valve (OR, 1.09; 95% CI, 1.05-1.13), in-hospital deaths (OR, 1.08; 95% CI, 1.03-1.14), or patients who experienced a major vascular complication (OR, 1.09; 95% CI, 1.05-1.12).Conclusions and RelevanceIn this observational cohort study performing a national analysis of outcomes after TAVR, it was found that risk-adjusted 30-day mortality increased modestly from January 2019 to March 2022. However, no site-level, patient-related, or process-related factors were identified that could explain these findings. Although the absolute increase in risk-adjusted mortality during the study period was relatively small, these findings warrant continued surveillance.
