Abstract
Background Left ventricular thrombus (LVT) is a significant complication in STEMI. Previous studies were conducted prior to modern timely percutaneous reperfusion networks. Current expert opinion suggests incidence in the current era has decreased. We conducted a systematic review and meta-analysis to better understand the incidence and diagnosis of LVT in patients with STEMI treated with timely percutaneous techniques as assessed by multimodality imaging. Methods Cochrane, EMBASE, LILACS, and MEDLINE were searched over the last 10 years only including studies using contemporary techniques. The primary outcome was detection of LVT in patients via echocardiogram with or without contrast or Cardiac MRI (cMRI) following STEMI (both anterior and any territory) treated with PCI. Data was pooled across studies and statistical analysis was conducted via random effects model. Results 31 studies were included. 18 studies included data on any territory STEMI, totaling 14,172 patients, and an incidence of 5.6% [95% CI 4.3-7.0]. 18 studies were included in analysis for anterior STEMI, totaling 7382 patients and incidence of 12.7% [95% CI 9.8-15.6]. Relative to cMRI as a gold standard, the sensitivity of non-contrast echocardiography to detect LVT was 58.2% [95% CI 46.6-69.2] with a specificity of 97.8% [95% CI 96.3-98.8]. Conclusions Incidence of LVT in STEMI patients treated with contemporary timely percutaneous revascularization is in keeping with historical data and remains significant, suggesting this remains an ongoing issue for further investigation. Numerically, both cMRI and contrast echo detected more LVT compared to non-contrast echo in any-territory STEMI patients.

ESC Heart Fail 2021; 8:5248-5258. [PMID: 34498435 PMCID: PMC8712797 DOI: 10.1002/ehf2.13605] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 08/02/2021] [Accepted: 08/25/2021] [Indexed: 11/17/2022] Open
Abstract
AIMS This study aimed to identify echocardiographic determinants of left ventricular thrombus (LVT) formation after acute anterior myocardial infarction (MI). METHODS AND RESULTS This case-control study comprised 55 acute anterior MI patients with LVT as cases and 55 acute anterior MI patients without LVT as controls, who were selected from a cohort of consecutive patients with ischemic heart failure in our hospital. The cases and controls were matched for age, sex, and left ventricular ejection fraction. LVT was detected by routine/contrast echocardiography or cardiac magnetic resonance imaging during the first 3 months following MI. Formation of apical aneurysm after MI was independently associated with LVT formation [72.0% vs. 43.5%, odds ratio (OR) = 5.06, 95% confidence interval (CI) 1.65-15.48, P = 0.005]. Echocardiographic risk factors associated with LVT formation included reduced mitral annular plane systolic excursion (<7 mm, OR = 4.69, 95% CI 1.84-11.95, P = 0.001), moderate-severe diastolic dysfunction (OR = 2.71, 95% CI 1.11-6.57, P = 0.028), and right ventricular (RV) dysfunction [reduced tricuspid annular plane systolic excursion < 17 mm (OR = 5.48, 95% CI 2.12-14.13, P < 0.001), reduced RV fractional area change < 0.35 (OR = 3.32, 95% CI 1.20-9.18, P = 0.021), and enlarged RV mid diameter (per 5 mm increase OR = 1.62, 95% CI 1.12-2.34, P = 0.010)]. Reduced tricuspid annular plane systolic excursion (<17 mm) significantly associated with increased risk of LVT in anterior MI patients (OR = 3.84, 95% CI 1.37-10.75, P = 0.010), especially in those patients without apical aneurysm (OR = 5.12, 95% CI 1.45-18.08, P = 0.011), independent of body mass index, hypertension, anaemia, mitral annular plane systolic excursion, and moderate-severe diastolic dysfunction. CONCLUSIONS Right ventricular dysfunction as determined by reduced TAPSE or RV fractional area change is independently associated with LVT formation in acute anterior MI patients, especially in the setting of MI patients without the formation of an apical aneurysm. This study suggests that besides assessment of left ventricular abnormalities, assessment of concomitant RV dysfunction is of importance on risk stratification of LVT formation in patients with acute anterior MI.

Abstract
Background Animal models are well established for studying the effects of alkaloids in preventing myocardial ischemia-reperfusion injury. However, few studies have investigated the therapeutic effects of alkaloids in humans. This meta-analysis and systematic review assessed the efficacy of alkaloids in attenuating infarct size in rats with myocardial ischemia-reperfusion injury. Methods An integrated literature search including the PubMed, Embase, and Cochrane Library databases was performed to identify studies that evaluated the therapeutic effects of alkaloids on myocardial ischemia-reperfusion injury in rats. The main outcome was infarct size, and SYRCLE's risk of bias tool was used to assess the quality of the studies. Results 22 studies were brought into the meta-analysis. Compared with the effects of vehicle, alkaloids significantly reduced infarct size (standardized mean difference (SMD) = -0.45; 95% confidence interval (CI) = -0.64 to - 0.26). In subgroup analyses, isoquinoline alkaloids (SMD = -0.43; 95%CI = -0.70 to - 0.16) significantly reduced infarct size versus the control. Conclusion Isoquinoline alkaloids can potentially alleviate myocardial ischemia-reperfusion injury. This meta-analysis and systematic review supply a reference for research programs aiming to develop alkaloid-based clinical drugs. This trial is registered with CRD42019135489.

Abstract
Despite advances in medical and device therapy, patients with heart failure remain at high risk for morbidity and mortality. Experimental and clinical studies have shown an association between heart failure and a hypercoagulable state, and that patients with heart failure experience an increased incidence of stroke and other thromboembolic events, regardless of whether they are in atrial fibrillation. Although oral anticoagulation is recommended when atrial fibrillation is present, the benefits of this therapy in patients with heart failure in sinus rhythm are uncertain. Older randomized controlled trials comparing warfarin with antiplatelet therapy were, for the most part, underpowered and failed to show convincing benefits of warfarin therapy in this population. Several recent studies that assessed the effects of low-dose direct-acting oral anticoagulant therapy in patients with coronary artery disease in sinus rhythm either included or specifically targeted patients with heart failure. Post hoc analysis of their results showed that this treatment strategy was associated with improved outcomes in patients with acute coronary syndrome or stable coronary artery disease and also a significant reduction in thromboembolic events, including ischemic stroke. This review presents the rationale for anticoagulant therapy in patients with heart failure in sinus rhythm, discusses gaps in our knowledge base, offers suggestions for when anticoagulation might be considered, and identifies potential directions for future research.

Predictive utility of left heart catheterization indices for left ventricular thrombus formation after anterior ST-elevation myocardial infarction. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 34:106-111. [PMID: 33461935 DOI: 10.1016/j.carrev.2021.01.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 12/22/2020] [Accepted: 01/12/2021] [Indexed: 11/12/2022]
Abstract
BACKGROUND Left ventricular thrombus (LVT) has a 5% incidence after anterior ST-elevation myocardial infarction (STEMI). Multiple risk factors predispose to LVT formation, including left ventricular systolic dysfunction and infarct size, however measurable predictors during index left heart catheterization (LHC) have not been determined. METHODS We performed a retrospective analysis of patients presenting between January 2010 and September 2017 with anterior STEMI who had in-hospital transthoracic echocardiography (TTE). LHC variables that were assessed included coronary anatomy, location of culprit stenosis, presence of diffuse stenosis, number of severely diseased vessels, apical akinesis on left ventriculogram (LVG), left ventricular end diastolic pressure, and success of percutaneous coronary intervention (PCI). RESULTS Of 598 consecutive anterior STEMI patients, records and inpatient TTE results were available in 425 patients. The incidence of LVT was 6.8% (n = 29). After multivariate adjustment, severe triple vessel coronary disease (OR = 8.27, CI = 2.97-23.00, p ≤0.001), apical akinesis on LVG (OR = 6.74, CI = 1.48-30.73, p = 0.014), wrap-around left anterior descending (LAD) anatomy (OR = 5.10, CI = 1.97-13.23, p = 0.001), and failure of recanalization after PCI (OR = 3.94, CI = 1.06-14.66, p = 0.04) were predictors for LVT formation. The combined negative predictive value (NPV) for the absence of these four indices was 99.2%. CONCLUSION Severe triple vessel disease, apical akinesis on LVG during index admission, wrap-around LAD, and failure of recanalization after PCI are associated with increased risk of LVT formation after anterior STEMI. The high NPV for the absence of these indices could serve as a risk stratification tool for LVT risk to guide early TTE utilization.

Abstract
Thrombosis in COVID-19 is increasingly recognized and is generally associated with a high mortality rate. The key clinical question of this report was whether COVID-19 could be complicated with cardiac thrombus and pulmonary embolism in Asian population. We demonstrated the case series of thrombosis in Thai patients with confirmed severe acute respiratory syndrome coronavirus 2 infection. One patient had the first case of a large left ventricular thrombus, and three other patients had pulmonary embolism. All patients were male and had low absolute lymphocyte count, while lactate dehydrogenase level and d-dimer were markedly elevated, especially at the time when the thrombosis was diagnosed. All patients had severe COVID-19 with pneumonia. Two patients who needed mechanical ventilation were successfully extubated. After hospitalization for 13-49 days, pneumonia and thrombosis improved and all of them could be discharged from the hospital. Thrombosis is common in COVID-19 and could present in both arterial and venous sites even in Asian populations. d-dimer is a strong marker to predict thrombosis and could be a prognostic predictor for severity of COVID-19.

Abstract
Background and objectives: Ejection fraction (EF) is a measurement of heart function that reflects the portion of pumped out blood from the filled left ventricle per each heartbeat. The current study aimed to investigate the prevalence of left ventricular thrombus in patients with EF lower than 35% by using Transthoracic Echocardiography (TTE). Methods: In this prospective study, 82 cardiac patients underwent TTE procedure in order to assess the presence of left ventricular thrombus (LVT) from January 1st to December 31st 2017 at the Military Cardiac Centre in Sana’a, Yemen. Results: Out of 82 patients enrolled in this study, the mean age was 49.13 ± 14.8 years and 87.8% were male. The mean of EF was 31.16% and LVT was found in 6.1%. The spontaneous contrast was seen in 25.6% of patients indicating strong relationship with low EF (p < 0.001). Among patients with low EF, ischemic heart disease (IHD) was identified in 50%, hypertension in 30.5%, diabetes mellitus (DM) type 2 in 23.2%, and hyperlipidemia 12.2%. Exactly 80% of LVT were detected in IHD patients with dilated cardiomyopathy (DCMP) and 80% of detected LVT were apical in site. Conclusion: Cardiac patients with low ejection fraction developed left ventricular thrombosis, and most of the affected patients were ischemic heart disease with dilated cardiomyopathy. Interestingly, spontaneous contrast was found high significantly in these patients, which may reflect the continuous process of thrombus formation.

Abstract
BACKGROUNDS The prognosis and management of left ventricular thrombus (LVT) following acute myocardial infarction (AMI) have not been well evaluated since the advent of primary percutaneous coronary intervention (PCI). We therefore conducted a meta-analysis to assess the prognostic effect of LVT after AMI in primary PCI era and investigate the impact of triple therapy on outcomes. METHODS We searched MEDLINE, EMBASE and the Cochrane Library for studies conducted in primary PCI era up to 29 March 2019, compering the incidence of embolic events and mortality after AMI between LVT patients and Non-LVT patients. Random-effect models were used. Subgroup analysis was done by comparing triple therapy treated LVT group with Non-LVT group. RESULT A total of 12 studies were included. LVT was associated with increased risk of embolic events and long-term mortality (RR 3.97, 95%CI 2.68-5.89, P < 0.0001; RR 2.34, 95%CI 1.38-3.96, P = 0.002). Subgroup analysis was also done by comparing triple therapy treated LVT group with Non-LVT group. Despite a downward tendency was observed, the embolic risk of triple therapy subgroup was higher than non-LVT group (RR 2.79, 95%CI 1.32-5.91, P = 0.007). Triple therapy subgroup had a similar mortality rate compared with non-LVT group (RR 0.93, 95%CI 0.34-2.52, P = 0.88). CONCLUSION In primary PCI era, LVT formation after AMI indicated a fourfold increased embolic risk and twofold long-term mortality rate. Triple therapy may be a safe way to improve the outcomes, but still need to be confirmed by future trials.

Abstract
Myocardial infarction (MI) remains one of the leading contributors to overall mortality and morbidity in the modern world, even with recent advances in medicine. Various complications can arise following an MI, particularly with delayed or inadequate treatment. Even though many of these complications are uncommon, they can have a significant impact on patient outcomes. Some of these complications can be diagnosed based on clinical, laboratory and echocardiographic evaluation. Other times, however, cardiac MR and multidetector CT are necessary in their diagnosis and proper evaluation. Accurate detection of these complications is an important aspect of optimising prompt and effective patient care, leading to better clinical outcomes. It is the goal of this article to review the role of cross-sectional imaging in patients with post-MI as well as the characteristic imaging findings and differential diagnosis of common and uncommon complications of MI.

Abstract
BACKGROUND AND OBJECTIVES Left ventricular (LV) apical thrombi are usually present with LV dilatation, and oral anticoagulants reduce embolic risk in these patients. However, echocardiographic data regarding thrombus resolution remain limited. We studied its echocardiographic features that were associated with early resolution (within 1 month). METHODS We performed a retrospective observational study by reviewing baseline and follow-up echocardiographic images and medical records in patients with LV apical thrombi. RESULTS Between January 2005 and December 2017, 77 patients (59 males, mean 61±12 years old) were enrolled. Patients were classified into 2 groups based on duration of thrombus resolution: group 1 showing resolution within 1 month (n=23) and group 2 with persistence after 1 month (n=54). Thrombus size was significantly smaller in group 1 (10.7±4.2 vs. 12.1±5.5 mm, p=0.046). Grade 1 mobility (partially mobile; odds ratio [OR], 7.800; p=0.012) and grade 2 mobility (highly mobile; OR, 14.625; p=0.002) were significantly associated with the early resolution. Round thrombi were associated with early resolution than mural form (OR, 3.187; p=0.026). Multivariate analysis showed that the mobility was the most important parameter, and a highly mobile (grade 2 mobility) LV apical thrombi showed earlier resolution (OR, 12.525; p=0.013). During the follow-up over 62±44 months, 25 patients (32.5%) had ≥1 adverse clinical events. The late resolution of thrombi was associated with poor long-term clinical outcomes (hazard ratio, 5.727; p=0.020). CONCLUSIONS Mobility of LV apical thrombi was the most important parameter associated with early thrombus resolution. Late resolution of LV apical thrombi was associated with poor long-term clinical outcomes.
