Long-term effects of radiofrequency ablation on symptom severity, depression, anxiety and quality of life in patients with atrial fibrillation: a longitudinal observational study.

Introduction: Atrial fibrillation (AF) is the most common cardiac arrhythmia, significantly affecting patients' quality of life (QoL) and increasing the risk of complications such as heart failure, stroke and dementia. In addition to the physical burden, psychological distress, including depression and anxiety, is prevalent among patients with AF and can exacerbate clinical symptoms and worsen overall well-being. While radiofrequency ablation (RFA) is widely used for rhythm control in AF, its long-term effects on both physical and psychological outcomes, including symptom severity, anxiety, depression and QoL, remain underexplored.

Prognostic impact of type 2 diabetes mellitus and coronary microvascular dysfunction in patients undergoing rotational atherectomy during PCI.

Background: The combined predictive value of type 2 diabetes mellitus (T2DM) and coronary microvascular dysfunction (CMD) in rotational atherectomy (RA) patients during the PCI remains unclear. The study examined whether the co-occurrence of DM and CMD, determined by angiography-derived index of microcirculatory resistance in RA patients influences clinical outcomes.

Methods: This was a retrospective, multicenter, observational study involving 452 patients at 3 medical centers.

A Patient With Pulmonary Hypertension Carrying Loss-of-Function Variant.

In a recent study conducted by Laura Stourm et al., the authors identified that patients with pulmonary hypertension (PH) harboring loss-of-function variants in the gene exhibit a unique spectrum of phenotypes. These include pulmonary involvement with lung parenchymal abnormalities and emphysema, as well as a range of extrapulmonary manifestations such as dysmorphic facial features, epilepsy, congenital heart defects, valvular and aortic diseases, thrombocytopenia, and periventricular nodular heterotopia (PVNH).

Analysis of risk factors for complications in echocardiography-guided percutaneous intramyocardial septal radiofrequency ablation.

Background: The feasibility of percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) for the treatment of hypertrophic obstructive cardiomyopathy (HOCM) has been previously reported. However, limited investigation has been conducted regarding the complications associated with this procedure.

Objective: This study aims to analyze the risk factors affecting the occurrence of complications during PIMSRA, such as pericardial effusion, ventricular premature beats, and interventricular septal perforation.

Targeting pro-inflammatory T cells as a novel therapeutic approach to potentially resolve atherosclerosis in humans.

Atherosclerosis (AS), a leading cause of cardio-cerebrovascular disease worldwide, is driven by the accumulation of lipid contents and chronic inflammation. Traditional strategies primarily focus on lipid reduction to control AS progression, leaving residual inflammatory risks for major adverse cardiovascular events (MACEs). While anti-inflammatory therapies targeting innate immunity have reduced MACEs, many patients continue to face significant risks.

Accuracy of death risk prediction models for acute coronary syndrome patients: a systematic review and meta-analysis.

Introduction: This study systematically evaluates the accuracy of several death risk prediction models for patients with acute coronary syndrome (ACS) through evidence-based methods. We identify the most accurate and effective ACS death risk prediction model and provide an evidence-based basis for clinical healthcare personnel to evaluate their choice of death risk prediction model for ACS patients.

Evidence Acquisition: An evidence-based approach was used to study the current death risk prediction model for ACS.

Association between dietary patterns and cardiovascular diseases: A review.

Cardiovascular disease (CVD), especially atherosclerosis, is the primary cause of global deaths. It accounts for millions of deaths annually. Even a small reduction in CVD through preventive treatment can have a substantial impact.

Analysis of Risk Factors for Complications after Percutaneous Coronary Intervention in Patients with Acute ST-segment Elevation Myocardial Infarction.

Background: Acute ST segment elevation myocardial infarction (ASTEMI) is the most common and serious type of AMI, percutaneous coronary intervention (PCI) is currently the most commonly used approach for clinical treatment of ASTEMI. After PCI, patients with ASTEMI are very prone to various complications, which will seriously threaten their health and life safety.

Objective: This study aims to analyze the risk factors for complications in patients with acute ST-segment elevation myocardial infarction (ASTEMI) treated with percutaneous coronary intervention (PCI).

Malnutrition Predicts Adverse Outcomes After Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis.

Background: Several studies have shown that malnutrition helps to predict the occurrence of adverse outcomes after transcatheter aortic valve replacement. However, there is still controversy and uncertainty regarding the prevalence and consequences of malnutrition. We performed a systematic review and meta-analysis to assess the relationship between malnutrition and poor postoperative outcomes in transcatheter aortic valve replacement.

Analysis of risk factors for systemic inflammatory response syndrome in patients after transcatheter aortic valve replacement.

Objective: Our aim was to determine the risk factors of postoperative systemic inflammatory response syndrome (SIRS) in patients with transcatheter aortic valve replacement (TAVR), identify those with a high risk of SIRS, and help reduce SIRS occurrence.

Methods: A retrospective cohort study was conducted to collect the clinical data of patients who underwent TAVR from January 2014 to December 2019 at a tertiary hospital in Zhejiang Province. The study included 156 men and 94 women.

Factors affecting ozone sensitivity of tobacco Bel-W3 seedlings.

Background: Since 1962, the tobacco variety Nicotiana tabacum cv. Bel-W3 has been used worldwide as an ozone (O3) bio-indicator. The use of indicator plants to monitor O3 pollution has proven problematic when trying to correlate the severity of injury to ambient O3 concentration.

[Study of severe hepatitis treated with a hybrid artificial liver support system].

Objectives: To evaluate the efficacy of a hybrid artificial liver support system in the treatment of chronic severe hepatitis.

Methods: The hybrid artificial liver support system (HALSS) consisted of a bioreactor containing more than 5 x 10(9) porcine hepatocytes and plasma exchange device. 15 patients with chronic severe viral hepatitis were treated with the hybrid system.
