Background: Bruton Tyrosine Kinase inhibitors (BTKi) are targeted therapies that have demonstrated promising results in the treatment of hematological malignancies; however, they are associated with adverse cardiac events. Direct comparisons of the cardiotoxic profile between old-generation and new-generation BTKi are limited. Research Question: Are novel BTKi associated with a lower incidence of cardiac adverse events compared with ibrutinib? Aims: We aimed to perform a systematic review and meta-analysis of cardiac events from studies comparing new-generation BTKi versus ibrutinib in patients with hematological malignancies. Methods: We searched PubMed, Embase, and Cochrane Library for studies comparing any new-generation BTKi with ibrutinib in patients with hematological malignancies. Outcomes included 1) risk of cardiac events; 2) atrial fibrillation (AF); 3) rate of treatment discontinuations due to AF; and 4) hypertension. We pooled risk ratios (RR) with 95% confidence intervals (CI). Statistical analysis was performed using R software 4.3.1, under a random-effects model. Heterogeneity was assessed using I 2 statistics. Results: We included four randomized controlled trials with 1905 patients, of whom 957 (50%) received new-generation BTKi. Age ranged from 28 to 90 years, with 1337 (70%) male patients. Prior lines of systemic therapy ranged from none to 12. Overall cardiac events were significantly lower in patients who received novel BTKi compared with those who received ibrutinib (RR 0.75; 95% CI 0.63 to 0.90; p=0.002; I 2 =0%; Fig.1A). New-generation BTKis were associated with a statistically significant reduction in the risk of AF (RR 0.48; 95% 0.35 to 0.64; p<0.001; I2=0% Fig.1B) and treatment discontinuation due to AF (RR 0.07; 95% CI 0.01 to 0.34; p=0.001; I 2 =0%), compared with ibrutinib. However, there was no statistically significant reduction in the risk of hypertension with novel BTKi relative to ibrutinib (RR 0.58; 95% CI 0.34 to 1.01; p=0.053; I 2 =81%). Conclusion: Our findings suggest that treatment with new-generation BTKi is associated with a significant reduction in the risk of cardiac events, AF, and AF-related treatment discontinuation compared with the old-generation BTKi.

INTRODUCTION: AI-based EKG has shown good accuracy for diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with reduced ejection fraction (LVEF <40%) is not yet well established. Research question: What it is the sensitivity and specificity of artificial-based electrocardiogram to diagnose heart failure with low ejection fraction(cut-off of 40%) Aims: We conducted a meta-analysis and systematic review to evaluate the accuracy of artificial intelligence electrocardiograms in predicting an ejection fraction below 40%. METHODS: We searched PubMed, Embase and Cochrane Library for studies evaluating the performance of AI EKGs in diagnosing HFrEF. We computed true positives, true negatives, false positives and false negatives events to estimate pooled sensitivity, specificity and area under the curve, using R software version 4.3.1, under a random-effects model. RESULTS: We identified 8 studies,including 136151 patients with a paired artificial intelligence enabled electrocardiogram with an echocardiography. 9349(6.8%) patients had an ejection fraction below 40% according to the echocardiogram. The AI-ECG data yielded areas under the receiver operator of, sensitivity of 0.861(0.815-0.897), and specificity of 0.874(0.834-0.905) , and area under the curve of 0.929(0.876-0.949). Mean/median age ranged from 60±9 to 67.8±14.4 years. CONCLUSIONS: In this systematic review and meta-analysis, the use of electrocardiogram-based artificial intelligence models demonstrated high sensitivity and specificity for the diagnosis of heart failure with an ejection fraction below 40%

Background: Cyclophosphamide is an alkylating agent of the nitrogen mustard class that has become standard of care for graft-versus-host disease prophylaxis after hematopoietic stem cell transplantation. Although its cardiac toxicity in conditioning regimens is well-documented, data on cardiac events after administration of post-transplant cyclophosphamide (PT-Cy) administration remains limited. Research Question: Is PT-Cy associated with a higher incidence of cardiac adverse events compared with no PT-Cy? Aims: We aimed to perform a systematic review and meta-analysis of cardiac events from studies comparing PT-Cy versus no PT-Cy in patients with hematological disorders who received hematopoietic stem cell transplantation. Methods: We searched PubMed, Embase, and Cochrane Library for studies comparing PT-Cy versus no PT-Cy in patients with hematological conditions who received hematopoietic stem cell transplantation. We pooled risk ratios (RR) with 95% confidence intervals (CI). Statistical analyses were performed using Review Manager 5.4.1, under a random-effects model. Heterogeneity was assessed using I2 statistics. Results: We included four studies, all of which were retrospective, with 1,546 patients, of whom 826 (53%) received PT-Cy. Age ranged from 18 to 77 years, and 840 (54%) were male. A total of 1549 allogeneic transplants were performed, primarily for malignant hematological conditions. The conditioning regimens used were myeloablative (52%), reduced intensity (33%), non-myeloablative (8%), and sequential (7%). The most common cardiac events in patients receiving PT-Cy were heart failure (28%) and cardiomyopathy (27%), followed by arrhythmias (25%), pericarditis/pericardial effusion (14%) and acute coronary syndrome (5%). The incidence of adverse cardiac events was significantly higher in patients who received PT-Cy compared with those who did not receive PT-Cy (RR 2.05; 95% CI 1.36, 3.10; p<0.001; I 2 =44%). Conclusion: These findings suggest that PT-Cy is associated with a higher incidence of adverse cardiac events, the most common of which is heart failure/cardiomyopathy.

Introduction: The efficacy and safety of use and impact of pulmonary artery catheter (PAC) in patients with cardiogenic shock (CS) treated with Impella remains unclear. The use of PAC in conjunction with Impella for patients with CS might be associated with improved clinical outcomes and increased safety compared to the use of Impella alone. We aimed to perform a systematic review and meta-analysis comparing Impella with versus without PAC for patients with CS. Methods: We systematically searched PubMed, Embase, and Cochrane databases for studies comparing PAC use in patients with CS treated with Impella. We pooled odds ratios (OR) with 95% confidence intervals (CI) applying random-effects model. We used R version 4.3.2 for statistical analyses. Results: We included two observational studies comprising 11,463 patients, of whom 6,058 (53%) had PAC. Compared with no PAC, the use of PAC was associated with a significantly lower in short-term mortality rates (37% vs. 42%; OR 0.83; 95% CI 0.77-0.90; p<0.01; Figure 1A). There was no significant difference in the incidence of arrhythmias 59% vs. 63%; OR 1.14; 95% CI 0.92-1.41 p=0.44; Figure 1B) or renal complications between groups (47% vs. 50%; OR 1.08; 95% CI 1.00-1.17; p=0.06; Figure 1C). Conclusions: In patients with CS, adjunctive PAC to Impella is associated with lower mortality rates, but no significant difference in arrhythmias and renal complications. Randomized controlled trials are warranted to further validate this results.

ABSTRACT The triglyceride/high-density lipoprotein (TG/HDL) ratio emerges as a promising marker for cardiovascular risk. However, the relationship between overall serum lipid levels and hemorrhagic stroke (HS) remains uncertain. Therefore, our study aims to explore the association between this novel index and mortality in HS patients. Utilizing a retrospective-prospective framework from January 2020 to August 2023, we scrutinized data from 104 hospitalized patients diagnosed with HS, with particular attention to their medical backgrounds and lipid profiles. Age (odds ratio [OR], 1.078; 95% confidence interval [CI], 1.032–1.125; P = 0.001), atrial fibrillation (OR, 0.237; 95% CI, 0.074–0.760; P = 0.015), glucose level (OR, 1.121; 95% CI, 1.007–1.247; P = 0.037), and TG/HDL index (OR, 0.368; 95% CI, 0.173–0.863; P = 0.020) emerged as independent predictors for in-hospital mortality, as determined by both univariable and multivariable logistic regression analyses. Our results add weight to the growing evidence backing the utility of the TG/HDL index in assessing cardiovascular risk among HS patients. They emphasize the necessity of adopting a comprehensive risk assessment and management strategy that incorporates both traditional markers and novel indicators.
