A systematic review and meta-analysis. Heart Lung 2024; 67:121-136. [PMID: 38754272 DOI: 10.1016/j.hrtlng.2024.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 04/28/2024] [Accepted: 04/29/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND Since the introduction of direct oral anticoagulants (DOACs) and their comparison with vitamin K antagonists (VKAs), conflicting results have been reported regarding the optimal treatment for left ventricular thrombosis (LVT). OBJECTIVES In this meta-analysis, we intend to comprehensively evaluate the safety and efficacy of these treatments. METHODS All clinical trials and cohorts that compared the efficacy or safety of VKAs with DOACs in the treatment of LVTs were systematically searched until April 15, 2023. RESULTS The results of 32 studies with a pooled sample size of 4213 patients were extracted for meta-analysis. DOACs, especially rivaroxaban and apixaban, cause faster resolution, lower mortality, and fewer complications (SSE and bleeding events) than VKAs in the management of LVTs. CONCLUSION Compared with VKAs, DOACs result in significantly faster (only rivaroxaban) and safer resolution of left ventricular thrombosis.

Abstract
BACKGROUND AND OBJECTIVE Left ventricular thrombus (LVT) formation in patients with acute myocardial infarction (AMI) or cardiomyopathies is not uncommon. The optimal oral anticoagulation therapy for resolving LVT has been under intense debate. Vitamin K antagonists (VKAs) remain the anticoagulant of choice for this condition, according to practice guidelines. Evidence supporting the use of direct oral anticoagulants (DOACs) in the management of LVT continues to grow. We performed a systematic review and meta-analysis to compare the efficacy and safety of DOACs versus VKAs. METHODS A comprehensive literature search was carried out in PubMed, Cochrane Library, Web of Science, Embase, and Scopus databases in July 2023. The efficacy outcomes of this study were thrombus resolution, ischemic stroke, systemic embolism, stroke/systemic embolism, all-cause mortality, and adverse cardiovascular events. The safety outcomes were any bleeding, major bleeding, and intracranial hemorrhage. A total of twenty-seven eligible studies were included in the meta-analysis. Data were analyzed utilizing Stata software version 15.1. RESULTS There was no significant difference between DOACs and VKAs with regard to LVT resolution (RR = 1.00, 95% CI 0.95-1.05, P = 0.99). In the overall analysis, DOACs significantly reduced the risk of stroke (RR = 0.74, 95% CI 0.57-0.96, P = 0.021), all-cause mortality (RR = 0.70, 95% CI 0.57-0.86, P = 0.001), any bleeding (RR = 0.75, 95% CI 0.61-0.92, P = 0.006) and major bleeding (RR = 0.67, 95% CI 0.52-0.85, P = 0.001) when compared to VKAs. Meanwhile, in the sub-analysis examining randomized controlled trials (RCTs), the aforementioned outcomes no longer differed significantly between the DOACs and VKAs groups. The incidences of systemic embolism (RR = 0.81, 95% CI 0.54-1.22, P = 0.32), stroke/systemic embolism (RR = 0.85, 95% CI 0.72-1.00, P = 0.056), intracranial hemorrhage (RR = 0.59, 95% CI 0.23-1.54, P = 0.28), and adverse cardiovascular events (RR = 0.99, 95% CI 0.63-1.56, P = 0.92) were comparable between the DOACs and VKAs groups. A subgroup analysis showed that patients treated with rivaroxaban had a significantly lower risk of stroke (RR = 0.24, 95% CI 0.08-0.72, P = 0.011) than those in the VKAs group. CONCLUSION With non-inferior efficacy and superior safety, DOACs are promising therapeutic alternatives to VKAs in the treatment of LVT. Further robust investigations are warranted to confirm our findings.

Direct oral anticoagulants (DOAC) versus vitamin K antagonist in left ventricular thrombus: An updated meta-analysis. Health Sci Rep 2023; 6:e1736. [PMID: 38028683 PMCID: PMC10667961 DOI: 10.1002/hsr2.1736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 10/29/2023] [Accepted: 11/06/2023] [Indexed: 12/01/2023] Open
Abstract
Background and Aims Current clinical guidelines for treating left ventricular thrombus (LVT) are limited by inadequate evidence to inform the comparative efficacy of oral anticoagulants. In this meta-analysis, we aimed to compare the efficacy and safety of direct oral anticoagulants (DOAC) to vitamin K antagonists (VKA) in patients with LVT. Methods Four standard databases were searched for relevant literature comparing the efficacy and safety between DOAC and VKA for LVT treatment, published before August 19, 2023. Both the randomized controlled trials and observational studies were included in the analysis. The outcomes of interest were the resolution of LVT, all-cause mortality, stroke, systemic embolism, and bleeding. Data from the selected studies were extracted and analyzed using RevMan 5.4 using odds ratio. Results Among 3959 studies from the database search and bibliography review, 33 were included in the analysis. LVT resolution was observed in 72.59% in the DOAC group versus 67.49% in the VKA group (odds ratio [OR]: 1.28, confidence interval [CI]: 1.07-1.53). Mortality was lower in the DOAC group (11.71% vs. 18.56%) (OR: 0.60, CI: 0.36-1.00; borderline statistical significance). Likewise, bleeding events (9.60% vs. 13.19%) (OR: 0.65, CI: 0.52-0.81) and stroke (7.54% vs. 11.04%) (OR: 0.71, CI: 0.53-0.96) were also significantly lower in the DOAC group. Conclusion DOAC use for LVT showed better thrombus resolution and reduced risk of bleeding and stroke compared to VKA. Likewise, DOAC use was associated with lower mortality with borderline statistical significance.

Abstract
Meta-analysis may increase the risk of random errors. Trial sequential analysis (TSA) has been developed to adjust for these random errors. We conducted TSA on the efficacy and safety of direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) in left ventricular thrombus (LVT) patients in order to estimate how many additional patients should be required to draw definite conclusions. PubMed, Scopus, and Cochrane Library databases were searched for articles directly comparing DOACs and VKAs for LVT in LV thrombus resolution, stroke, any thromboembolism, major bleeding, any bleeding, and all-cause death. TSA was conducted with a cumulative Z-curve, monitoring boundaries, and required sample size. A simulated trial was run and TSA estimated the sample sizes of trials needed to draw definite conclusions. Of 4749 articles, 25 studies were used for the analysis. TSA revealed the current sample size already demonstrated superiority of DOACs in LV thrombus resolution and stroke, and futility in any thromboembolism and all-cause death. Two other outcomes did not achieve the required sample size. The sample size of new trials needed to demonstrate the superiority of DOACs over VKAs was estimated 400 for any bleeding. Corresponding trials needed to demonstrate no significant differences could be estimated for major bleeding and any bleeding (n = 200 and n = 2000, respectively). Current results show that the sample size required to draw definite conclusions was not reached for two outcomes, and there was a risk of random error. Further randomized controlled trials with sample sizes estimated by TSA will work effectively to obtain valid conclusions.

Abstract
Aim To perform a systematic review and meta-analysis of efficacy and safety of direct oral anticoagulants (DOAC) as compared to vitamin K antagonists (VKA) in the treatment of left ventricular (LV) thrombosis.Material and methods A search was performed in PubMed and Google Scholar for studies that compared DOAC and VKA in the treatment of LV thrombosis with respect of thromboembolic events, hemorrhagic complications, and thrombus resolution. The effect was evaluated with the odds ratio (OR) that was computed using a fixed effects model.Results For these systematic review and meta-analysis, 19 studies were selected, including 2 randomized and 17 cohort studies. The articles included into these systematic review and meta-analysis, were published from 2018 through 2021. In total, 2970 patients (mean age, 58.8 лет; 1879 (61.2 %) men) with LV thrombus were included into the meta-analysis. Mean follow-up duration was 17.9 months. The meta-analysis showed no significant difference between DOAC and VKA in the incidence of the study outcomes: thromboembolic events (OR, 0.86; 95 % CI: 0.67-1.10; р=0.22), hemorrhagic complications (OR, 0.77; 95 % CI: 0.55-1.07; р=0.12), thrombus resolution (OR, 0.96; 95 % CI: 0.76-1.22; р=0.77). In a subgroup analysis, rivaroxaban compared to VKA significantly (79%) reduced the risk of thromboembolic complications (OR, 0.21; 95 % CI: 0.05-0.83; р=0.03) with no significant differences in hemorrhagic events (OR, 0.60; 95 % CI: 0.21-1.71; р=0.34) or thrombus resolution (OR, 1.44; 95 % CI: 0.83-1.31; р=0.20). The apixaban treatment group had significantly more (4.88 times) cases of thrombus resolution than the VKA treatment group (OR, 4.88; 95 % CI: 1.37-17.30; р=0.01); for apixaban, data on hemorrhagic and thromboembolic complications were not available.Conclusions The therapeutic efficacy and side effects of the DOAC treatment for LV thrombosis were similar to those of VKA with respect of thromboembolic events, hemorrhage, and thrombus resolution.

Abstract
AIMS Left ventricular thrombus (LVT) increases the risk of thrombotic events and mortality. Vitamin K antagonists (VKAs) used to treat LVT have several known risks, as a result of which direct oral anticoagulant (DOAC) use has recently increased. We aimed to evaluate the safety and efficacy of DOACs and VKAs in treating LVT. METHODS AND RESULTS We searched PubMed, Embase, Cochrane Library trials, and Web of Science databases for studies published before 19 April 2022, involving DOAC versus VKA treatment for patients with LVT. This meta-analysis comprised 21 studies (total patients, n = 3172; DOAC group, n = 888; VKA group, n = 2284). A statistically significant reduction in bleeding events was observed in patients on DOACs vs. those on VKAs (risk ratio (RR) = 0.73, P = 0.004). Patients on DOACs residing in North American and European regions and those with ischaemic heart disease (IHD) had a significantly lower risk of bleeding events than patients residing in other regions or those with a different LVT aetiology, respectively (RR = 0.78, P = 0.04; RR = 0.38, P = 0.02; and RR = 0.63, P = 0.009). A statistically significant reduction in stroke in patients on DOACs versus VKAs (RR = 0.72, P = 0.03) was observed, and patients on DOACs residing in North America and those with IHD had a significantly lower risk of stroke (RR = 0.73, P = 0.04, and RR = 0.61, P = 0.03, respectively). Compared with VKAs, DOACs are statistically associated with an increase in LVT resolution at 1 month (RR = 1.96, P = 0.008). No statistical between-group difference in all-cause mortality (RR = 0.72, P = 0.05), systemic embolism (RR = 0.87, P = 0.74), stroke or systemic embolism (RR = 0.90, P = 0.50), and LVT resolution at the end of follow-up (RR = 1.06, P = 0.13) was observed. CONCLUSIONS Compared with VKAs, DOACs significantly reduce the risk of bleeding events and stroke in LVT patients, but mortality was similar in both groups. The advantages are apparent not only in patients belonging to the predominantly white residential areas such as North American and European regions but also in patients with LVT due to IHD. DOACs show promising effects in treating LVT compared with VKAs.
