Aims: The role of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in patients with cardiac amyloidosis (CA) is controversial. However, they have shown encouraging results in several clinical settings, including heart failure, myocardial infarction, chronic kidney disease, and various forms of restrictive cardiomyopathy. The current study aims to evaluate the tolerability and efficacy of SGLT2i in patients with CA.

Methods and results: PubMed, Scopus, Cochrane Library, and Embase were scanned for eligible articles up to 28th of March 2025. Safety endpoints included the cumulative prevalence of adverse events (AEs) and drug discontinuation (DD) in the SGLT2i-group. Efficacy endpoints were the pooled risk ratio (RR) of all-cause death (ACD) and hospitalization due to worsening heart failure (WHF) between treatment- and control-groups, as well as the difference between mean change of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in both treatment- and control-groups. Thirteen observational studies, encompassing 19 227 patients, were included in the meta-analysis. Sodium-glucose co-transporter 2 inhibitors use in patients with CA resulted to be tolerable, as demonstrated by a low absolute cumulative prevalence of both AEs [8%; 95% confidence interval (CI) 2-17, nine studies, 603 patients] and DD (4%; 95% CI: 1-7, nine studies, 603 patients). Furthermore, its use was associated with a reduction in the risk of ACD (RR 0.59; 95% CI: 0.48-0.72) and NT-proBNP levels (median difference: -525.54; 95% CI: -718.09 to -332.98), despite no significant association with WHF was noted.

Conclusion: The administration of SGLT2i proved to be well tolerated in patients with CA. Randomized controlled trials are urgently needed to confirm the prognostic improvement associated with their use in this clinical setting.

Aims: Transcatheter mitral valve replacement (TMVR) has become a feasible alternative to surgical mitral valve replacement (SMVR) in selected patients at high surgical risk. The risk of valve thrombosis following SMVR and TMVR, and the optimal antithrombotic therapy following these procedures, remains uncertain. We aimed to compare the incidence of bioprosthetic mitral valve thrombosis (bMVT) after SMVR and TMVR, and the incidence of bMVT between patients on different antithrombotic regimens.

Methods and results: A literature search of Medline, Embase, and Cochrane Library was performed between January 2000 and August 2024. Random-effects models were used to derive pooled estimates of the incidence of bMVT in the absence of prior or active endocarditis and valve thrombosis. A total of 47 studies (6170 patients, total follow-up 9541.8 patient-years) were eligible for inclusion. The overall incidence of bMVT was 5.05 [95% confidence interval (CI) 3.18-8.01, I2 = 82%] per 100-patient-years. Subclinical bMVT was more common than clinically significant bMVT: incidence 19.11 vs. 7.91 per 100-patient-years, adjusted incidence rate ratio (aIRR) 4.62 (95% CI 1.39-15.36), P = 0.012. bMVT was numerically more common after TMVR than SMVR, but the comparison was not statistically significant: incidence 7.03 vs. 0.58 per 100-patient-years, aIRR 2.19 (95% CI 0.72-6.72), P = 0.170. Patients on vitamin-K antagonists (VKA) had a lower incidence of bMVT than patients on direct oral anticoagulants (DOAC; incidence 5.72 vs. 17.08, aIRR 0.31, 95% CI 0.13-0.73, P = 0.007).

Conclusions: bMVT is not uncommon, with numerically higher incidence in transcatheter compared to surgical valves, but the comparison was not statistically significant. VKAs are associated with a lower incidence of bMVT compared to DOACs.

Aims: A genotype-guided P2Y12-inhibitor de-escalation strategy, switching acute coronary syndrome (ACS) patients without a CYP2C19 loss-of-function allele from ticagrelor or prasugrel to clopidogrel, has shown to reduce bleeding risk without affecting the effectivity of therapy by increasing ischaemic risk. We estimated the cost-effectiveness of this personalized approach compared to standard dual antiplatelet therapy (DAPT; aspirin plus ticagrelor/prasugrel) in the Netherlands.

Methods and results: We developed a 1-year decision tree based on results of the FORCE-ACS registry, comparing a cohort of ACS patients who underwent genotyping with a cohort of ACS patients treated with standard DAPT. This was followed by a lifelong Markov model to compare lifetime costs and quality-adjusted life years (QALYs) for a fictional cohort of 1000 patients. The cost-effectiveness analysis was performed from the perspective of the Dutch healthcare system. A genotype-guided de-escalation strategy led to an increase of 57.73 QALYs and saved €808788 compared to standard DAPT based on a lifetime horizon. Probabilistic sensitivity analysis showed that the genotype-guided strategy was cost-saving in 96% and increased QALYs in 87% of simulations. The intervention remained cost-effective in the scenario where prices for all P2Y12 inhibitors were equalized. The genotype-guided strategy remained dominant in various other scenarios and sensitivity analyses.

Conclusion: A genotype-guided de-escalation strategy in patients with ACS was both cost-saving and yielded higher QALYs compared to standard DAPT, highlighting its potential for implementation in clinical practice. Trial registration: ClinicalTrials.gov identifier: NCT03823547.

Background and aims: Amiodarone is frequently prescribed alongside direct oral anticoagulants (DOACs) in atrial fibrillation. There are concerns regarding drug-drug interactions (DDIs) between amiodarone and DOACs. The literature is conflicting on the clinical implications of this DDI, hence we conducted a meta-analysis to compare bleeding risk among patients receiving DOACs, with and without concurrent amiodarone.

Methods and results: A systematic search was conducted for studies published between 1 January 2009 and 26 June 2024 in MEDLINE via PubMed, Embase, and CENTRAL. Included studies compared major bleeding in patients on concurrent amiodarone and DOACs to those on DOACs without amiodarone. Event rates were used to calculate odds ratios (ORs), which were pooled with a random-effects model. Nine studies were identified, which included 124 813 patients on amiodarone/DOACs, and 314 074 on DOACs. The average age was 77.2 years in the amiodarone/DOAC group, compared to 74.4 years in the DOAC group (P = 0.21). Among DOAC patients, there was a statistically significant increase in major bleeding with concurrent amiodarone (OR 1.22, 95% confidence interval (CI) 1.03-1.44, P = 0.02, I2 = 88%). Intracranial bleeding rate was numerically higher in the amiodarone/DOAC group (1.0 vs. 0.4%), but the difference did not reach statistical significance (OR 2.20, 95% CI 0.53-9.06, P = 0.27, I2 = 100%). There were no significant differences in gastrointestinal bleeding (OR 1.10, 95% CI 0.98-1.23, P = 0.12, I2 = 62%) and all-cause mortality (OR 1.38, 95% CI 0.70-2.73, P = 0.35, I2 = 99%).

Conclusion: Concurrent use of amiodarone and DOACs was associated with an increase in major bleeding. This should be considered when co-prescribing these medications.
