Remote monitoring-enabled insertable cardiac monitors (ICMs) are useful tools for arrhythmias and symptom management. This study sought to evaluate the outcome of ICM implantation in a large, heterogeneous cohort of pediatric and young adult patients.

Single centre, retrospective analysis of patients who underwent ICM implantation in 2010-2019. Patients were analysed according to age, symptoms, arrhythmias and underlying heart disease.

A total of 200 consecutive patients (58% male), aged 11.5 ± 5.8 years at ICM implantation, were included. Follow-up was 31 ± 18 months. Electrophysiologic study (EPS) was initially performed in 123 patients and was negative in 85%. Patients had no heart disease (57.5%), congenital heart defects (21%), channelopathies (14.5%), cardiomyopathies/heart tumors (8%). The commonest symptoms were syncope/presyncope (45.5%) and palpitations (12.5%). A definite diagnosis was made in 63% of patients (positive diagnosis in 25%, negative in 38%) after 8 (2-19) months of monitoring. EPS results and the presence/absence of an arrhythmia before ICM implantation had no impact on the diagnostic yield. Symptomatic patients as well as patients without structural heart disease showed higher diagnostic yield. Patients with a positive diagnosis underwent pacemaker/implantable cardioverter-defibrillator implantation (13%), pharmacological treatment (10.5%), or catheter ablation (1.5%).

In a large cohort of 200 children and young adults, ICMs with remote monitoring showed a high diagnostic yield (63%), especially in symptomatic patients and in patients without structural heart disease.

For women presenting with stable chest pain (SCP), the appropriate risk assessment strategy to identify individuals unlikely to benefit from further cardiovascular imaging testing (CIT) is debatable. Thus, the present study intended to compare two risk assessment strategies in these individuals.

2592 women with SCP who underwent coronary computed tomography angiography (CCTA) were divided into low and high risk group according to 2016 National Institute of Health and Care Excellence guideline-determined strategy (NICE strategy) and 2019 European Society of Cardiology guideline-determined strategy (ESC strategy), respectively. The associations of coronary artery disease (CAD), major adverse cardiovascular event (MACE) and other subsequent clinical outcomes with risk groups and net reclassification improvement (NRI) were evaluated to compare different strategies.

Both NICE strategy which focused on symptom evaluation and ESC strategy which was based on pretest probability (PTP) determined by ESC-PTP model and coronary artery calcium score-weighted clinical likelihood (CACS-CL) model classified a proportion (34.49% and 63.97%, respectively) of individuals into the low risk group. Compared to NICE strategy, ESC strategy indicated stronger associations between risk groups and obstructive CAD (odds ratio 27.63 versus 3.57), MACE (hazard ratios 4.24 versus 1.91), more intensive clinical management as well as a positive NRI (27.71%,

< 0.0001).

Compared to NICE strategy, ESC strategy which sequentially incorporated ESC-PTP model with CACS-CL model seemed to be associated with greater effectiveness in identifying individuals who may derive maximum benefit from further CIT in women presenting with SCP.

Recent advances in various imaging modalities, including three-dimensional electroanatomic mapping systems, magnetic resonance imaging, transesophageal and intracardiac echocardiography (ICE) have been adopted in catheter ablation of ventricular arrhythmias improving procedural outcome and safety. ICE is an imaging tool which provides real-time visualization of anatomical structures of the heart, facilitating catheter manipulation and navigation during ablation procedures. In this review we aim to highlight the benefits of ICE use in catheter ablation of ventricular arrhythmias and to describe practical techniques for visualization of cardiac structures with ICE during ventricular tachycardia ablations.

Elevated heart rate (HR) is associated with cardiovascular mortality and other events associated with acute myocardial infarction (AMI). The heart rate after discharge is likely superior to reflect the deteriorating heart function, which negatively responds to normal physical activity. This study aimed to explore the effect of HR at the first outpatient visit on clinical outcomes.

We retrospectively identified 605 patients with AMI. HRs at admission, discharge, and first outpatient visits were measured. The primary endpoint was defined as major adverse cardiovascular events (MACEs), including cardiovascular (CV) death, readmission for worsening heart failure, recurrent nonfatal myocardial infarction (MI), repeated coronary revascularization, and ischemic stroke.

During the follow-up period, 145 cases of MACE occurred, including 34 CV deaths, 31 recurrent MI, 89 revascularizations, 41 heart failures, and 4 strokes. The event group displayed an elevated HR at the first outpatient visit compared to the event-free group (

< 0.001). After adjustment for confounding risk factors, Cox models showed that the outpatient HR had the best correlation with MACE [Hazard ratio (HR) = 1.33, 95% confidence interval (CI) = 10.8-59.3,

< 0.01 for increments of 1 standard deviation (SD) in the outpatient HR) and CV mortality (HR = 1.18, 95% CI = 1.052-1.325,

< 0.01) compared with the other two HRs. The restricted spline model indicated that HR at the first post-discharge above 71 bpm was associated with CV mortality.

Elevated HR at the first outpatient visit over a period of 2-4 weeks is related to the adverse outcomes of AMI and may identify AMI patients at higher risk of CV mortality.

Timely reperfusion with primary percutaneous coronary intervention (PPCI) remains the gold standard in patients presenting with ST-segment elevation myocardial infarction (STEMI), limiting infarct size, preserving left ventricular ejection fraction (LVEF), and improving clinical outcomes. Despite this, a significant proportion of STEMI patients develop post-infarct heart failure. We review the current understanding and up-to-date evidence base for therapeutic intervention of ischaemia-reperfusion injury (IRI), a combination of myocardial ischaemia secondary to acute coronary occlusion and reperfusion injury leading to further myocardial injury and cell death. Multiple treatment modalities have been shown to be cardioprotective and reduce IRI in experimental animal models. Recent phase II/III randomised controlled trials (RCT) have assessed multiple cardioprotective strategies ranging from ischaemic conditioning, therapeutic hypothermia and hyperoxaemia to pharmacological therapies. While several therapies have been shown to reduce infarct size in animal models or proof-of-concept studies, many larger scale trial results have proven inconsistent and disappointing. Hard clinical outcomes remain elusive. We discuss potential reasons for the difficulties in translation to clinical practice.

The long-term effect of three-dimensional printed heart model (3DPHM) on knowledge acquisition of congenital heart disease (CHD) remains unknown. This prospective cohort study aims to investigate the role of 3DPHM in improving immediate knowledge gain and long-term knowledge retention on CHD among the medical students.

Fifty-three second and third year medical students were assigned into two groups to compare their immediate knowledge acquisition and knowledge retention after an education session on anatomy and pathophysiology of CHD. During the 1.5 hour-long education session, both the control (n = 25) and study groups (n = 28) had access to identical teaching materials digital 3D heart models, 2D diagrams, and medical images, except for 3DPHM which were only used in the study group. The immediate knowledge gain was assessed via an online quiz, whereas the long-term knowledge retention was assessed using another quiz in 6-weeks' time post-intervention. A survey was also conducted to evaluate the participsize, as well as categorizing the type of questions in the quiz, is needed to better assess the role of 3DPHM in different educational components.After reading with great interest the article entitled "Exploring the impact of the COVID-19 pandemic on provision of cardiology services a scoping review" redacted by Farah Yasmin et al., published by Reviews in Cardiovascular Medicine, we would like to add the following thoughts. Acute respiratory distress syndrome (ARDS) in Coronavirus disease 2019 (COVID-19) and pulmonary insufficiency reduces blood oxygen saturation and results in hypoxia. Therefore, the determining factor in the survival of patients with COVID-19 is their resistance to hypoxia. At the same time, it is the cardiovascular system that is an important and very sensitive link in the human adaptation to hypoxia. That is why it is necessary to carefully study the relationship between diseases of the heart, blood vessels, the reactivity of the cardiovascular system to hypoxia, and mortality in patients who develop ARDS with COVID-19.

Systemic inflammation can occur after transcatheter aortic valve replacement (TAVR) and correlates with adverse outcome. The impact of remote ischemic preconditioning (RIPC) on TAVR associated systemic inflammation is unknown and was focus of this study.

We performed a prospective controlled trial at a single center and included 66 patients treated with remote ischemic preconditioning (RIPC) prior to TAVR, who were matched to a control group by propensity score. RIPC was applied to the upper extremity using a conventional tourniquet. Definition of systemic inflammation was based on leucocyte count, C-reactive protein (CRP), procalcitonin (PCT) and interleukin-6 (IL-6), assessed in the first 5 days following the TAVR procedure. Mortality was determined within 6 months after TAVR. RIPC group and matched control group showed comparable baseline characteristics.

Systemic inflammation occurred in 66% of all patients after TAVR. Overall, survival after 6 months was significantly reduced in patients with systemic inflammation. RIPC, in comparison to control, did not significantly alter the plasma levels of leucocyte count, CRP, PCT or IL-6 within the first 5 days after TAVR. Furthermore, inflammation associated survival after 6 months was not improved by RIPC. Of all peri-interventional variables assessed, only the amount of the applied contrast agent was connected to the occurrence of systemic inflammation.

Systemic inflammation frequently occurs after TAVR and leads to increased mortality after 6 months. selleck chemicals RIPC neither reduces the incidence of systemic inflammation nor improves inflammation associated patient survival within 6 months.
