Background: In advanced heart failure patients, heart transplantation is currently the most effective treatment. However, in a low-organ environment, it is usually necessary to proceed in long-term mechanical circulatory support through left ventricular assist device (LVAD) implantation as bridge-to-transplantation METHODS: The study included all patients with advanced heart failure who underwent continuous flow LVAD implantation as a bridge to transplant strategy in our centre (n = 68). Following LVAD implantation and for the period that patients were on LVAD support, pump thrombosis, strokes, gastrointestinal bleeding and right heart failure occurrence rates were recorded. Outcomes were compared between patients implanted with HeartMate 3 (HM3) and HeartWare (hVAD) LVADs as well as between patients who did reach heart transplantation (HTx group) and those who did not (noHTx group).
Results: 35 out of 68 patients underwent heart transplantation at a mean time of 691 ± 457 days. 41 patients received a HeartWare hVAD and 27 a HeartMate 3 (HM3) device. HM3 patients had significantly better survival (p = 0.010) and lower complication rates (p = 0.025). Additionally, the noHTx group had significantly higher complication rates compared to the HTx group (p = 0.00041). The five-year estimated Kaplan-Meier survival rates following heart transplantation was 77%.
Conclusions: Patients with advanced heart failure gain substantial benefit from left ventricular assist devices awaiting heart transplantation. In a low organ donation environment, the need for reliable left ventricular assist devices can further improve the outcomes through the reduction of complications provided by current devices.

Background: Although several studies have highlighted the benefits of statins in improving arterial stiffness, there is limited research on whether pitavastatin, a more recently developed statin, has similar effects. This study aimed to investigate the impact of pitavastatin on arterial stiffness in patients with hypercholesterolemia.
Methods: This prospective study enrolled 115 patients with hypercholesterolemia (mean age 59 years; 22% female) who had not previously been treated with statins. Participants underwent lifestyle interventions followed by administration of pitavastatin (2 or 4 mg daily) if target low-density lipoprotein (LDL) cholesterol levels were not achieved. The primary outcome measured was the change in brachial-ankle pulse wave velocity (baPWV) from baseline after three months of treatment.
Results: Pitavastatin treatment significantly reduced LDL cholesterol by 41.1% (from 158 ± 28 to 93.0 ± 29.6 mg/dL; P < 0.001). Additionally, systolic blood pressure (SBP) decreased significantly from 130 ± 14 mmHg to 126 ± 14 mmHg (P < 0.001), representing a 2.9% reduction, and baPWV decreased significantly from 1,522 ± 325 to 1,407 ± 289 cm/s (P < 0.001), a 7.6% reduction. There was a significant correlation between changes in SBP and changes in baPWV (r = 0.565; P < 0.001). Even after adjusting for changes in SBP, the reduction in baPWV induced by pitavastatin remained statistically significant (P < 0.001).
Conclusions: A three-month treatment with pitavastatin effectively reduced arterial stiffness in patients with hypercholesterolemia, alongside significant improvements in lipid profiles and blood pressure reductions. These findings support the use of pitavastatin for managing key cardiovascular risk factors.

Objectives: This study investigated the association between the utilization of extracorporeal membrane oxygenation (ECMO) or intra-aortic balloon pump (IABP) and in-hospital mortality among patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock undergoing primary percutaneous coronary intervention (PCI).
Methods: Data encompassing 9635 cases of STEMI complicated by cardiogenic shock and treated with primary PCI using ECMO/IABP support were retrieved from the Chinese Cardiovascular Association database (2019-2021). We conducted an analysis to assess in-hospital survival disparities among percutaneous mechanical circulatory device recipients and explore the potential advantages of ECMO through multivariable logistic regression analysis within a propensity score-matched (1:2) cohort population.
Results: ECMO was administered to 2028 patients, while IABP was utilized in 7607 patients. Patients supported by ECMO showed a lower in-hospital mortality compared with those supported by IABP (7.2% vs. 15.1%, p<0.001). Within the propensity-matched (case : control=1:2) cohort, we noted a 34% reduced risk of in-hospital mortality among patients supported by ECMO compared to those supported by IABP (7.7% vs. 11.7%; odds ratio = 0.66; 95% CI, 0.53-0.80; p< 0.001) independent of age, sex, systolic blood pressure, obesity, smoke, hypertension, diabetes, dyslipidaemia, family history of coronary artery disease, coronary artery disease, stroke, atrial filiation, peripheral artery disease, chronic kidney disease, vascular lesion sites, 3A-grade hospital, and regional distributions in China.
Conclusions: Among patients undergoing primary PCI for STEMI complicated by cardiogenic shock, ECMO was associated with better in-hospital survival than IABP.

Background: VA ECMO has emerged as an effective rescue therapy in patients with cardiogenic shock refractory to standard treatment protocols and its use is rising worldwide in the last decade. Although experience and availability are growing, outcomes remain poor. There is need for evidence to ameliorate clinical practice and improve outcomes.
Methods: We retrospectively reviewed the medical records of all patients who were supported with VA ECMO for cardiogenic shock at our institution between January 2015 and January 2023. The study purpose was to compare outcomes between patients who were supported with central versus peripheral configuration.
Results: ECMO was applied in 108 patients of whom central configuration in 48 (44%) and peripheral in 60 (56%). Patients supported with central VA ECMO were more likely to be supported for post cardiotomy shock [OR 4.6 (CI 95% 2.03 - 10.41)], while patients in the peripheral group for chronic heart failure decompensation [OR 9.4 (CI 95% 1.16 - 76.3]. Central VA ECMO had worse survival during ECMO support (29.2% vs 51.7%, p=0.018) and at discharge (8% vs 37%, p=0.001). These patients were at high risk of complications, such as acute kidney injury (AKI), [OR 2.37 (CI 95% 1.06 - 5.3), p = 0.034] and major bleeding [OR 3.08 (CI 95% 1.36 - 6.94), p<0.001].
Conclusions: Patients on central VA ECMO were supported mainly for post cardiotomy shock, presented with more complications such as major bleeding and AKI and had worse survival to hospital discharge, compared with patients on peripheral VA ECMO. Patient selection, timing of implementation, cannulation strategy and configuration remain main determinants of clinical outcome.

Out-of-hospital cardiac arrest (OHCA) is a global public health problem. Lay bystanders witness almost half of OHCA, so early recognition is critical to allow immediate initiation of cardiopulmonary resuscitation (CPR) by the bystander. The present investigation aims to analyze the most recent scientific evidence of the effect of bystander CPR on survival after an OHCA. A systematic literature review was carried out at the "Web of Science," "Scopus," and "PubMed" databases, including publications from the last 20 years. After inclusion/exclusion criteria, 37 articles were identified. Results indicate that patients who receive CPR are more likely to survive than those who don't, and CPR is associated with a good quality of life post-OHCA. Emphasis should be placed on practicing chest compressions only when the bystander has not mastered the artificial ventilation technique. Finding an AED is the first step to using it in an OHCA situation. Correct use of an AED by laypeople is associated with nearly double the survival rate after an OHCA when compared to standard CPR. It is important to promote CPR and AED training to non-professionals, such as community residents and youth, as training is associated with higher success rates of effective CPR-AED. A mobile phone positioning system to recruit trained laypeople or text message alerts to send citizen volunteers as well as assistance through a mobile app appear to have significant advantages in practicing effective CPR. The benefits of bystander CPR outweigh the risk of injury to victims, highlighting the need to disseminate training to laypeople.

Background: The precise triggers for atherosclerotic plaque rupture and the underlying pathophysiology of coronary thrombogenesis remain elusive. Polymorphonuclear neutrophils, particularly their formation of neutrophil extracellular traps (NETs), have garnered attention in the context of coronary atherothrombosis. This study sought to explore the association of NETs burden with clinical and angiographic characteristics in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI) and thrombus aspiration (TA).
Methods: For this study, 336 consecutive STEMI patients undergoing pPCI were considered for TA. Aspirated thrombi underwent histological analysis and NETs quantification via immunohistochemistry. Potential associations of clinical variables and angiographic outcomes with NETs burden were assessed.
Results: Manual TA was selectively performed in 72 cases with increased thrombotic burden, and 60 thrombi were suitable for analysis and included in the current study. Most thrombi specimens displayed lytic features (63%), and almost three out of four were identified as white thrombi. Increased NETs burden was significantly associated with prolonged pain-to-balloon time (>300 min), OR = 10.29 (95% CI 2.11-42.22, p = 0.001), and stress-induced hyperglycemia OR = 6.58 (95% CI 1.23-52.63, p < 0.01) after multivariate regression analysis. Additionally, distal embolization, and left ventricular ejection fraction ≤40% were more frequent among patients with an elevated NETs burden OR = 16.9 (95% CI 4.23-44.52, p < 0.01) and OR = 3.2 (95% CI 1.05-12.1, p = 0.05), respectively.
Conclusion: Elevated NETs burden in STEMI thrombi may be due to delayed reperfusion and stress-induced hyperglycemia, and it is associated with an increased risk of distal embolization and lower left ventricular ejection fraction. Further research is needed to elucidate the role of NETs as a potential therapeutic target in acute atherothrombosis.
背景:动脉粥样硬化斑块破裂的确切诱因和冠状动脉血栓形成的潜在病理生理学仍然难以捉摸。多形核中性粒细胞,尤其是它们形成的中性粒细胞胞外陷阱(NETs),在冠状动脉粥样硬化血栓形成中引起了关注。本研究旨在探讨接受经皮冠状动脉介入治疗(pPCI)和血栓抽吸术(TA)的ST段抬高型心肌梗死(STEMI)患者的NETs负担与临床和血管造影特征之间的关系:在这项研究中,考虑对 336 名连续接受经皮冠状动脉介入治疗的 STEMI 患者进行血栓抽吸。抽吸出的血栓进行了组织学分析,并通过免疫组化对NETs进行了定量。评估了临床变量和血管造影结果与 NETs 负荷的潜在关联:对72例血栓负担加重的病例选择性地进行了人工TA,有60个血栓适合进行分析并纳入本次研究。大多数血栓标本具有溶解特征(63%),几乎四分之三的标本被鉴定为白色血栓。NETs负荷增加与疼痛至气球时间延长(>300分钟)(OR=10.29 (95% CI 2.11-42.22, p=0.001))和应激性高血糖(OR=6.58 (95% CI 1.23-52.63, p)明显相关:STEMI 血栓中 NETs 负荷升高可能是由于再灌注延迟、应激诱发的高血糖所致,并且与远端栓塞风险增加有关。需要进一步研究以阐明 NETs 在急性动脉粥样硬化血栓形成中作为潜在治疗靶点的作用。

Acute myocardial infarction (AMI) usually represents the clinical manifestation of atherothrombotic coronary artery disease (CAD) resulting from atherosclerotic plaque rupture. However, there are cases in which coronary angiography or coronary computed tomography angiography reveals patients with acute coronary syndrome with non-obstructive CAD. This clinical entity is defined as myocardial infarction with non-obstructive coronary arteries (MINOCA) and often considered as a clinical dynamic working diagnosis that needs further investigations for the establishment of a final etiologic diagnosis. The main causes of a MINOCA working diagnosis include atherosclerotic, non-atherosclerotic (vessel-related and non–vessel-related), and thromboembolic causes This literature review aimed to investigate the major thromboembolic causes in patients presenting with MINOCA regarding their etiology and pathophysiologic mechanisms, as well as diagnostic and treatment methods.
