UNASSIGNED: Periprocedural myocardial injury impacts clinical outcome after transcatheter aortic valve replacement (TAVR). The optimal medical management strategy for TAVR-related periprocedural myocardial injury has not been established.
UNASSIGNED: The authors aimed to investigate the prognostic association of renin-angiotensin system (RAS) inhibitors in patients with periprocedural myocardial injury after TAVR.
UNASSIGNED: In a prospective TAVR registry, patients were retrospectively stratified according to Valve Academic Research Consortium (VARC)-3 periprocedural myocardial injury and RAS inhibitor prescription after TAVR. The main outcomes of interest were prevalence of myocardial injury and cardiovascular death. Logistic and Cox proportional hazards regression were used to analyze outcomes of interest.
UNASSIGNED: Among 2,083 eligible patients undergoing TAVR between August 2007 and June 2023, 283 patients (13.8%) developed VARC-3 periprocedural myocardial injury. RAS inhibitors were prescribed in 197 patients (70%) with periprocedural myocardial injury and in 1,251 patients (71.2%) without injury. Compared with patients without periprocedural myocardial injury, patients with myocardial injury had an increased risk of cardiovascular death at 1 year (HRadjusted: 2.08; 95% CI: 1.39-3.11). The use of RAS inhibitors after TAVR was associated with a reduced risk of cardiovascular death in patients with and without periprocedural myocardial injury (HRadjusted: 0.46; 95% CI: 0.22-0.95, and HRadjusted: 0.44; 95% CI: 0.30-0.65, respectively).
UNASSIGNED: One out of 7 patients undergoing TAVR experienced periprocedural myocardial injury. VARC-3 periprocedural myocardial injury was associated with a 2-fold increased risk of cardiovascular death at 1 year after TAVR. The favorable association of RAS inhibitor prescription was consistent in patients with and without periprocedural myocardial injury. (SwissTAVI Registry; NCT01368250).

UNASSIGNED: Hospital admission for a critical illness episode creates communication breakpoints and can lead to medication discrepancies during hospital stays. Due to the patient\'s underlying condition and the care setting, chronic medications such as cardiovascular medication are often held, discontinued, or changed to alternative administration routes. Unfortunately, data on the optimal timing of cardiovascular drug reinitiation among intensive care unit (ICU) survivors are lacking.
UNASSIGNED: The primary objective of this study was to describe the prevalence of chronic cardiovascular medication taken before hospital admission and discontinued at ICU discharge and hospital discharge for critically ill patients. A secondary objective was to assess factors associated with medication discontinuation.
UNASSIGNED: We conducted a multicentered retrospective cohort study at 2 tertiary academic hospitals in Canada. All adult patients taking cardiovascular medication before ICU admission and surviving to hospital discharge between April 1, 2016, and April 1, 2017, were eligible.
UNASSIGNED: The main outcome of the study was the discontinuation of cardiovascular medication prescribed before ICU admission. The outcome was assessed through participants\' chart review.
UNASSIGNED: We included 352 patients with a median age of 71.0 years. A total of 155 patients (44.03%) had at least 1 cardiovascular medication discontinued during their stay. Our adjusted model uncovered 3 factors associated with cardiovascular medication discontinuation: male sex (odds ratio [OR] = 0.564, 95% confidence interval [CI] = 0.346-0.919), number of cardiovascular medications taken preadmission (OR = 1.669, 95% CI = 1.003-2.777 for 2 medications and OR = 3.170, 95% CI = 1.325-7.583), and the use of vasopressors (OR = 1.770, 95% CI = 1.045-2.997).
UNASSIGNED: Our study uncovered that cardiovascular medication discontinuation for ICU patients is frequent, especially for renin-angiotensin system (RAS) blockers. Data from our study could be used to reinforce site-specific protocols of medication reconciliation and optimization, as well as inform future protocols aimed at RAS blocker reinitiation follow-up.
UNASSIGNED: L’admission à l’hôpital pour un épisode de maladie grave crée des ruptures de communication et peut entraîner des écarts dans la médication pendant le séjour à l’hôpital. Il arrive souvent, selon l’état sous-jacent du patient et l’environnement de soins, que les médicaments destinés à traiter des maladies chroniques, comme les médicaments cardiovasculaires, soient poursuivis, cessés ou administrés par d’autres voies. On manque malheureusement de données sur le moment optimal pour la reprise du traitement cardiovasculaire chez les survivants des unités de soins intensifs (USI).
UNASSIGNED: L’objectif principal était de décrire la prévalence de l’arrêt, à la sortie de l’USI et de l’hôpital, des médicaments pris par les patients gravement malades pour traiter les maladies cardiovasculaires chroniques avant leur admission. Un objectif secondaire était d’évaluer les facteurs associés à l’arrêt du traitement.
UNASSIGNED: Nous avons mené une étude de cohorte rétrospective multicentrique dans deux hôpitaux universitaires tertiaires canadiens. Étaient admissibles tous les patients adultes qui prenaient des médicaments cardiovasculaires avant leur admission à l’USI entre le 1er avril 2016 et le 1er avril 2017 et qui avaient survécu jusqu’à leur sortie de l’hôpital.
UNASSIGNED: Le principal critère d’intérêt était l’arrêt du traitement cardiovasculaire prescrit avant l’admission à l’USI. Ce critère a été établi par l’examen des dossiers des sujets.
UNASSIGNED: Nous avons inclus 352 patients (âge médian : 71,0 ans) desquels 155 (44 %) avaient vu au moins un de leurs médicaments pour traiter une maladie cardiovasculaire cessé pendant leur séjour. Notre modèle corrigé a révélé trois facteurs associés à l’arrêt du traitement cardiovasculaire : être de sexe masculin (rapport de cotes [RC] : 0,564; IC95 % : 0,346-0,919), le nombre de médicaments cardiovasculaires pris avant l’admission (RC : 1,669; IC95 % : 1,003-2,777 pour deux médicaments, et RC : 3,170; IC95 % : 1,325-7,583) et l’utilisation de vasopresseurs (RC : 1,770; IC95 % : 1,045-2,997).
UNASSIGNED: Notre étude a révélé que l’arrêt du traitement contre les maladies cardiovasculaires chroniques, en particulier les inhibiteurs du SRA, est fréquent chez les patients hospitalisés aux soins intensifs. Les données de notre étude pourraient servir à renforcer les protocoles de bilan de médication et d’optimisation propre à chaque site de même que pour éclairer les futurs protocoles visant à assurer le suivi de la réinitiation des inhibiteurs du SRA.

BACKGROUND: The optimal medical treatment strategy after transcatheter aortic valve replacement (TAVR) has not been established, and might be affected by the extent of extravalvular cardiac damage. We aimed to investigate the prognostic association of renin-angiotensin system (RAS) inhibitors in TAVR patients stratified according to the extent of extravalvular cardiac damage.
METHODS: In a prospective TAVR registry, patients were retrospectively evaluated for baseline cardiac damage and classified into 5 stages of cardiac damage (0-4) according to established criteria. Clinical outcomes at 1 year were compared according to RAS inhibitor prescription at discharge.
RESULTS: Among 2247 eligible patients who underwent TAVR between August 2007 and June 2021, 1634 (72.7%) were prescribed RAS inhibitors at discharge. Eighty-three patients (3.7%) were classified as stage 0, 276 (12.3%) as stage 1, 889 (39.6%) as stage 2, 489 (21.8%) as stage 3, and 510 (22.7%) as stage 4. RAS inhibitor prescription after TAVR was associated with a reduced risk of 1-year mortality (adjusted hazard ratio [HRadjusted], 0.59; 95% confidence interval [CI], 0.45-0.77). The protective association was accentuated among patients with cardiac stages 3 and 4 (HRadjusted, 0.54 [95% CI, 0.32-0.92]; and HRadjusted, 0.58 [95% CI, 0.36-0.92], respectively), but not statistically significant in for those with stage 2 (HRadjusted, 0.70; 95% CI, 0.43-1.14).
CONCLUSIONS: In patients who underwent TAVR, we found a strong association of RAS inhibitor prescription and improved clinical outcome in the overall population, and there were no signs of heterogeneity across stages of cardiac damage.
BACKGROUND: NCT01368250.

UNASSIGNED: There is a lack of real-world evidence regarding the impact of concomitant metformin and renin-angiotensin system inhibitors (RASis) on sodium-glucose cotransporter-2 inhibitor (SGLT2i)-associated kidney outcomes. This study was aimed to investigate whether SGLT2i-associated kidney outcomes were modified by the concomitant use of metformin or RASis in patients with type 2 diabetes.
UNASSIGNED: SGLT2i users were identified from three electronic health record databases during May 2016 and December 2017 and categorized into those with and without concomitant use of metformin or RASis. Propensity score matching was performed to minimize baseline differences between groups. Study outcomes were mean estimated glomerular filtration rate (eGFR) change and time to 30%, 40%, and 50% eGFR reductions. A meta-analysis was performed to combine the estimates across databases.
UNASSIGNED: After matching, there were 6,625 and 3,260 SGLT2i users with and without metformin, and 6,654 and 2,746 SGLT2i users with and without RASis, respectively. The eGFR dip was similar in SGLT2i users with and without metformin therapy, but was greater in SGLT2i users with RASis compared to those without RASis. Neither metformin nor RASi use had a significant effect on SGLT2i-associated eGFR reductions, as evidenced by the hazard ratios (95% CIs) of 30% eGFR reductions for SGLT2is with versus without metformin/RASis, namely 1.02 (0.87-1.20)/1.09 (0.92-1.31). Such findings were also observed in the outcomes of 40% and 50% eGFR reductions.
UNASSIGNED: Using metformin or RASis did not modify SGLT2i-associated kidney outcomes in type 2 diabetes.

BACKGROUND: Many guidelines have recommended renin-angiotensin system inhibitors (RASI) as the first-line treatment for patients with chronic kidney disease (CKD). We studied RASI prescription trends from 2010 to 2019, and analyzed the characteristics associated with RASI prescription in Chinese hospitalized CKD patients.
OBJECTIVE: To study the prescription of renin angiotensin system inhibitors in hospitalized patients with CKD in China.
METHODS: It was retrospectively, cross-sectional reviewed RASI prescriptions in hospitalized CKD patients in China from 2010 to 2019. RASI prescribing trends were analyzed from 2010 to 2019, and bivariate and multivariate logistic regression analyses were conducted to identify characteristics associated with RASI prescription.
RESULTS: A total of 35090 CKD patients were included, with 10043 (28.6%) RASI prescriptions. Among these patients, 18919 (53.9%) met the criteria for RASI treatments based on the 2012 kidney disease: Improving global outcomes guidelines. Of these, 7246 (38.3%) patients received RASI prescriptions. RASI prescriptions showed an initial rapid increase from 2011 to 2012, reached its peak around 2015 and 2016, and then exhibited a subsequent slight decreasing trend. Both bivariate and multivariate analyses showed that several characteristics, including the male gender, age less than 60-year-old, nephrology department admission, lower CKD stage, history of hypertension or diabetes, proteinuria, glomerulonephritis as the CKD etiology, and non-acute kidney injury were associated with RASI prescriptions.
CONCLUSIONS: The frequency of RASI prescriptions showed an initial increase but a slight decreasing trend in more recent years. CKD patients with certain characteristics such as elderly age, advanced disease stage, surgery department admission, or acute kidney injury were less likely to receive RASI prescriptions. In the application of RASI in hospitalized CKD patients is insufficient. The actual clinical practice needs to be improved. The development of related research is helpful to guide the correct choice of clinical treatment strategy.

UNASSIGNED: The impact of renin-angiotensin system inhibitors (RASIs) on the outcome of hypertensive cancer patients undergoing immune checkpoint inhibitor (ICIs) therapy remains ambiguous. This investigation sought to elucidate the consequences of RASIs use on the prognosis for this specific patient group within the context of ICIs treatment, aspiring to provide a clearer basis for rational, evidence-driven choices in the clinical prescription of these medications.
UNASSIGNED: A comprehensive search was conducted on PubMed, Embase, Web of Science, and the Cochrane Library for original studies published up to 6 August 2023. Studies published in English reporting hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS) and/or progression-free survival (PFS) were included. All statistical analyses were executed utilizing R software (version 4.2.2).
UNASSIGNED: A total of 13 studies, encompassing approximately 12,595 patients, satisfied the inclusion criteria. Meta-analyses demonstrated a statistically significant association between the use of RASIs and a favorable outcome in OS (HR, 0.74; 95% CI, 0.62-0.88) and PFS (HR, 0.77; 95% CI, 0.62-0.96) among cancer patients receiving ICIs treatment.
UNASSIGNED: This investigation provides compelling evidence supporting the beneficial prognostic impact of RASIs on cancer patients receiving ICIs. RASIs present a viable option as antihypertensive agents for cancer patients with hypertension undergoing ICIs treatment. Further exploration and validation through prospective studies are necessary to establish definitive guidelines for the use of RASIs in managing hypertensive cancer patients undergoing immunotherapy with ICIs.

BACKGROUND: Renin-angiotensin system inhibitors (RASi) treatment is the basic therapy for IgA nephropathy (IgAN) patients. However, there is few of biomarker that can predict the efficacy of RASi. This study aimed to find urinary exosomal mRNAs related to the therapeutic effect of RASi in the treatment of proteinuria in IgAN patients.
METHODS: We divided IgAN patients in screening cohort into A1 (proteinuria increase at 3 months), B1 (proteinuria decrease less than 50 % at 3 months), C1 (proteinuria decrease more than 50 % at 3 months) groups according to changes of proteinuria after treatment. The urinary exosomes were collected before biopsy, RNAs were extracted and analyzed with the microarray assay. The candidate genes were screened by differentially expressed genes (DEGs) analysis and then validated by quantitative real-time polymerase chain reaction (qPCR) in a validation cohort. A receiver operating characteristic (ROC) curve was used to evaluate gene performance in predicting therapeutic effect on RASi reducing proteinuria in IgAN patients.
RESULTS: ECE1 and PDE1A mRNAs were significantly different among the three groups, and were gradually decreased among A1, B1 and C1 groups. In the validation cohort, the level of urinary exosomal ECE1 and PDE1A mRNAs were also significantly lower in A2 group compared with C2 group(ECE1, P < 0.001;PDE1A, P < 0.01). Besides, the level of ECE1 mRNA was also lower in B2 group compared with C2 group (P < 0.01). The ROC curve verified that urinary exosomal ECE1 and PDE1A gene level predicted RASi efficacy in IgAN patients with area under curve (AUC) 0.68 and 0.63 respectively.
CONCLUSIONS: Urinary exosomal ECE1 and PDE1A mRNAs expression can serve as potential biomarkers for predicting the RASi efficacy to reduce proteinuria in IgAN patients.

It is controversial whether renin-angiotensin system inhibitors (RASIs) should be stopped in patients with advanced chronic kidney disease (CKD). Recently, it was reported that stopping RASIs in advanced CKD was associated with increased mortality and cardiovascular (CV) events; however, it remains unclear whether stopping RASIs before dialysis initiation affects clinical outcomes after dialysis, which this study aimed to evaluate. In this multicenter prospective cohort study in Japan, we included 717 patients (mean age, 67 years; 68% male) who had a nephrology care duration ≥90 days, initiated hemodialysis, and used RASIs 3 months before hemodialysis initiation. The multivariable adjusted Cox models were used to compare mortality and CV event risk between 650 (91%) patients who continued RASIs until hemodialysis initiation and 67 (9.3%) patients who stopped RASIs. During a median follow-up period of 3.5 years, 170 (24%) patients died and 228 (32%) experienced CV events. Compared with continuing RASIs, stopping RASIs was unassociated with mortality (adjusted hazard ratio [aHR]: 0.82; 95% confidence interval [CI]: 0.50-1.34) but was associated with higher CV events (aHR: 1.59; 95% CI: 1.06-2.38). Subgroup analyses showed that the risk of stopping RASIs for CV events was particularly high in patients aged <75 years, with a significant interaction between stopping RASIs and age. This study revealed that patients who stopped RASIs immediately before dialysis initiation were associated with subsequent higher CV events. Active screening for CV disease may be especially beneficial for these patients.

BACKGROUND: Patients with elevated preoperative plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP >100 pg ml-1) experience more complications after noncardiac surgery. Individuals prescribed renin-angiotensin system (RAS) inhibitors for cardiometabolic disease are at particular risk of perioperative myocardial injury and complications. We hypothesised that stopping RAS inhibitors before surgery increases the risk of perioperative myocardial injury, depending on preoperative risk stratified by plasma NT-proBNP concentrations.
METHODS: In a preplanned analysis of a phase 2a trial in six UK centres, patients ≥60 yr old undergoing elective noncardiac surgery were randomly assigned either to stop or continue RAS inhibitors before surgery. The pharmacokinetic profile of individual RAS inhibitors determined for how long they were stopped before surgery. The primary outcome, masked to investigators, clinicians, and patients, was myocardial injury (plasma high-sensitivity troponin-T ≥15 ng L-1 or a ≥5 ng L-1 increase, when preoperative high-sensitivity troponin-T ≥15 ng L-1) within 48 h after surgery. The co-exposures of interest were preoperative plasma NT-proBNP (< or >100 pg ml -1) and stopping or continuing RAS inhibitors.
RESULTS: Of 241 participants, 101 (41.9%; mean age 71 [7] yr; 48% females) had preoperative NT-proBNP >100 pg ml -1 (median 339 [160-833] pg ml-1), of whom 9/101 (8.9%) had a formal diagnosis of cardiac failure. Myocardial injury occurred in 63/101 (62.4%) subjects with NT-proBNP >100 pg ml-1, compared with 45/140 (32.1%) subjects with NT-proBNP <100 pg ml -1 {odds ratio (OR) 3.50 (95% confidence interval [CI] 2.05-5.99); P<0.0001}. For subjects with preoperative NT-proBNP <100 pg ml-1, 30/75 (40%) who stopped RAS inhibitors had myocardial injury, compared with 15/65 (23.1%) who continued RAS inhibitors (OR for stopping 2.22 [95% CI 1.06-4.65]; P=0.03). For preoperative NT-proBNP >100 pg ml-1, myocardial injury rates were similar regardless of stopping (62.2%) or continuing (62.5%) RAS inhibitors (OR for stopping 0.98 [95% CI 0.44-2.22]).
CONCLUSIONS: Stopping renin-angiotensin system inhibitors in lower-risk patients (preoperative NT-proBNP <100 pg ml -1) increased the likelihood of myocardial injury before noncardiac surgery.

BACKGROUND: The therapeutic efficacy of renin-angiotensin system inhibitors (RASi) in elderly patients with hypertension and at risk of fractures has been in the limelight because of accumulating evidence that localized RAS activation in bone tissue leads to osteoclastic bone resorption, resulting in osteoporosis. This study set out to investigate the association between RASi use and fracture incidence in a large cohort.
METHODS: We employed a nested case-control design to investigate the association between RASi use and newly developed fractures. A case was defined as a patient newly diagnosed with a fracture between January 2004 and December 2015. We selected 1,049 cases and controls using 1:1 propensity score matching. Conditional logistic regression analysis was conducted to estimate the association between RASi exposure and fracture incidence.
RESULTS: Overall, RASi usage was significantly associated with lower odds for fracture incidence (ever-users vs never-users: OR, 0.73; 95% CI, 0.59-0.91). We found that ARB-only users experienced fewer fractures than RASi-never users (OR, 0.65; 95% CI, 0.49-0.86), whereas ACEi-only users or ARB/ACEi-ever users did not. In subgroup analysis, RASi-ever users without cerebrovascular disease, those with a BMI exceeding 23, and statin exposure had significantly lower ORs.
CONCLUSIONS: The present study established a significant association between RASi use and reduced fracture incidence, thus highlighting the potential clinical utility of RASi use as a preventive strategy in elderly patients at risk for osteoporotic fractures.
