Anthracyclines are effective chemotherapeutic agents widely used to treat various cancers, but their use is limited by the risk of cardiotoxicity and heart failure. While strategies like dose reduction have been explored, there are no well-established therapies to mitigate this risk. Emerging evidence suggests sodium-glucose cotransporter 2 inhibitors (SGLT2i) may have cardioprotective effects, providing a rationale for investigating their potential utility in anthracycline-treated patients. We conducted a systematic review and meta-analysis to synthesize available evidence on the efficacy of SGLT2i in reducing heart failure incidence and mortality in patients undergoing anthracycline-based cancer therapy. Relevant studies were identified through comprehensive database searches and screened based on predefined criteria. Data extraction and quality assessment were performed independently by two reviewers. Four observational studies, encompassing 5,590 patients, were included. The pooled analysis showed a higher but non-significant risk of developing heart failure in the non-SGLT2i group compared to the SGLT2i group (RR = 0.67, 95% CI: 0.40-1.41). The risk of all-cause mortality was significantly lower in patients receiving SGLT2i (RR = 0.55, 95% CI: 0.39-0.77). This meta-analysis suggests SGLT2i are associated with a lower risk of mortality and heart failure incidence in anthracycline-treated patients, although larger studies are needed to confirm these findings. The mechanisms underlying these potential benefits require further elucidation. Despite limitations, this analysis highlights the promising role of SGLT2i as a cardioprotective strategy in this high-risk population., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Tabowei et al.)

The aim of this meta-analysis was to determine the effect of pulmonary hypertension (PH) on survival in patients undergoing transcatheter aortic valve replacement (TAVR). The present study was conducted according to the guidelines of Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA). We conducted a comprehensive search of electronic databases including PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science from January 1, 2015, to March 10, 2024. Outcomes assessed in this meta-analysis included early and late all-cause mortality and cardiovascular mortality. Total 15 studies were integrated into the pooled analysis to assess the impact of PH on outcomes among patients undergoing TAVR, comprising a total sample size of 35,732 individuals. The pooled prevalence of PH stood at 52.57% (n=18,767). Predominantly, the studies were conducted in the United States (n=6), followed by Germany (n=3), with one study each from Japan, Italy, Switzerland, Brazil, Poland, and Australia. Pooled analysis showed that risk of short-term mortality was greater in patients with PH compared to patients without PH (risk ratio (RR): 1.46, 95% CI: 1.19 to 1.80). Risk of long-term mortality was greater in patients with PH (RR: 1.42, 95% CI: 1.29 to 1.55). Risk of cardiovascular mortality was also greater in patients with PH compared to patients without PH (RR: 1.66, 95% CI: 1.36 to 2.02). We advocate for further research to address gaps in understanding different types of PH and their impacts on mortality and cardiovascular outcomes., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

The objective of this network meta-analysis was to assess the efficacy and safety of apixaban, dabigatran, rivaroxaban, and edoxaban in patients diagnosed with atrial fibrillation and valvular heart disease. A comprehensive search was conducted across various electronic databases, including PubMed, Embase, and Web of Science, from inception to February 15, 2024. The search strategy utilized a combination of medical subject headings (MeSH) terms and relevant keywords related to valvular heart disease, atrial fibrillation, anticoagulant therapy, and study design, such as randomized controlled trials and observational studies. The outcomes evaluated in this analysis comprised the incidence of stroke or systemic embolism (SE), as well as the occurrences of major bleeding events. A total of 10 studies were incorporated into this meta-analysis, encompassing 40,662 participants. Of these, 12,385 received apixaban, 2,829 received dabigatran, 13,662 received rivaroxaban, 2,582 received edoxaban, and 9,202 received warfarin. The duration of follow-up in the included studies ranged from 3 to 54 months. Among the four direct oral anticoagulants (DOACs) studied, apixaban demonstrated a significant reduction in the risk of stroke or SE when compared to other DOACs and warfarin, highlighting its efficacy in patients with atrial fibrillation and valvular heart disease. Additionally, apixaban exhibited a lower risk of major bleeding events, further emphasizing its favorable safety profile compared to the other agents assessed. In conclusion, our findings suggest that apixaban may be more effective and safer than other DOACs and warfarin in this patient population. However, additional studies are warranted to compare the various DOACs in this cohort to identify the optimal treatment strategy for preventing adverse outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Huma et al.)
