Multimorbidity Patterns in Patients with Pulmonary Arterial Hypertension Identified Through Hospital Discharge Records: A Network-Based Analysis

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Considerable variability exists in the clinical presentations of pulmonary arterial hypertension (PAH). Greater understanding of the comorbidities observed in Chinese patients with PAH is urgently needed.

This 10-year retrospective analysis was based on clinical data from hospital discharge records for individuals diagnosed with PAH (n = 2584. Propensity score matching was used to match patients with PAH to individuals without a PAH diagnosis in a ratio of 1:1, by age, sex, discharge time, and department, over the same period. Multimorbidity networks were constructed based on sex and age, and used the cosine index to measure the co-occurrence of chronic diseases.

FGF-23: A Novel and Critical Predictor of Reduced Left Atrial Appendage Emptying Velocity in Patients with Atrial Fibrillation

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Current AF management guidelines have introduced the CARE treatment model to strengthen management strategies; in this acronym, the “A” indicates anticoagulation therapy. However, despite anticoagulation, approximately one-third of patients with AF experience ischemic stroke, which is closely associated with factors such as poor adherence to anticoagulation, inappropriate anticoagulant dosing, and reduced LAAev.

Therefore, patients with reduced LAAev should be closely monitored and, when necessary, LAA excision or closure should be considered to decrease residual thrombotic risk. Although TEE can accurately measure LAAev, its high technical requirements and potential esophageal injury limit its widespread use in routine examinations of patients with AF.

Approaches for Localizing the Origin of PVCs in the Outflow Tract: Future Perspectives and Challenges

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Idiopathic ventricular arrhythmias (IVAs) are a type of arrhythmias with focal origins. The locations of most such arrhythmias have been identified and confirmed. In cases in which pharmacological treatment is ineffective or limited, radiofrequency catheter ablation is a therapeutic option whose success rate largely depends on accurate IVA localization.

The current standard approach for localizing the origin of IVAs involves comparing the normal electrocardiogram (ECG) with the characteristic ECG of the arrhythmia. This comparison includes analysis of parameters such as the QRS wave polarity in different leads, QRS duration, R/S ratio, and S-R difference in precordial leads.

Clinical Application of Artificial Intelligence in the Diagnosis, Prediction, and Classification of Coronary Heart Disease

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Coronary heart disease (CHD), the most common cause of mortality globally, poses a formidable challenge to modern healthcare systems. Artificial intelligence (AI) is playing an increasingly important role in multiple diagnostic applications of CHD, by facilitating early intervention and personalized treatment. This article describes the state of the art and provides clinicians with updated insights into the transformative potential of AI to enhance CHD detection.

AI can be used to increase diagnostic and prognostic accuracy. However, its reliance on homogeneous numerical data might potentially lead to misdiagnoses and unnecessary radiation exposure in diagnosing CHD.

Effects of Cardiac Abnormalities on the Brain, Revealed by Brain Magnetic Resonance Imaging and Genetics

Announcing a new article publication for Cardiovascular Innovations and Applications journal. The heart is the central organ of the human circulatory system. Both congenital and acquired structural changes in the heart can lead to hemodynamic alterations affecting the function of various organs, including the brain. Recent advancements in magnetic resonance imaging (MRI) have provided further evidence of the heart’s influence on the brain.

Investigating this connection is crucial for understanding the pathological mechanisms through which cardiac abnormalities contribute to brain-related diseases, and providing additional support for the heart-brain axis theory.

Association Between Malnutrition and Guideline-Directed Medical Therapy Utilization at Discharge in Hospitalized Patients with Heart Failure

Announcing a new article publication for Cardiovascular Innovations and Applications journal. This study was aimed at identifying crucial gaps in guideline-directed medical therapy (GDMT) application among malnourished patients at Beijing Anzhen Hospital. Data from patients with heart failure (HF) admitted between January 1, 2018, and April 30, 2023, were analyzed. Malnutrition was assessed with Controlling Nutritional Status (CONUT) and Geriatric Nutritional Risk Index (GNRI) scores.

GDMT regimens were defined as follows. The triple-therapy regimen included β-blockers, renin-angiotensin system inhibitors (RASIs), and mineralocorticoid receptor antagonists (MRAs).

Exploration of the Causal Roles of Immune Cells and Inflammatory Proteins in Aortic Dissection via Mendelian Randomization

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Aortic dissection is a life-threatening condition with complex immunological underpinnings. This article explored the causal relationships among immune cells, inflammatory proteins, and aortic dissection, through Mendelian randomization analysis. A two-step Mendelian randomization approach was used to assess potential mediators, focusing on the roles of blood immune cells and inflammatory proteins.

GWAS data was analyzed for 731 immune cell traits, 91 inflammatory proteins, and aortic dissection. Single-nucleotide polymorphisms were used as instrumental variables, and analyses were conducted with inverse variance weighting and sensitivity tests to ensure robustness.

Chronic Kidney Disease and Cognitive Dysfunction after Cardiac Surgery

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Patients with chronic kidney disease (CKD) often encounter cardiovascular complications, most commonly coronary heart disease. Although coronary artery bypass grafting is an effective treatment for this condition, many patients experience cognitive dysfunction after cardiac surgery.

The complex interactions among functional status, general anesthesia, cardiopulmonary bypass, and surgical trauma in patients with CKD elevate the risk of neurological issues and increase the mortality rates after surgery.

Potential Therapeutic Targets of PANoptosis for Myocardial Infarction: A Summary-Data-Based Mendelian Randomization Study Integrating eQTL, mQTL, and Multi-GWAS Data

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Acute myocardial infarction (MI), a critical and dangerous manifestation of coronary heart disease resulting from arterial or bypass graft thrombosis, rapidly induces myocardial ischemia and hypoxia, and culminates in cardiac failure.

PANoptosis, an inflammasome-dependent, inflammatory form of programmed cell death, involves a complex molecular network in which pyroptosis, apoptosis, and necroptosis mediate apoptotic programs in an interconnected manner. However, the causal relationships and regulatory mechanisms linking MI and PANoptosis have not been clarified. In addition, DNA methylation regulates PANoptosis pathways, thereby mediating changes in cardiac diseases.

MicroRNAs Have an Immunomodulatory Role in Diabetes Mellitus and Diabetic Cardiomyopathy

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Diabetic cardiomyopathy (DCM), an independent diabetes complication, is characterized by abnormalities in myocardial structure, function, and metabolism, including diminished myocardial contractility, myocardial hypertrophy, and fibrosis. Factors such as hyperglycemia, metabolic disorders, microangiopathy, inflammation, oxidative stress, and insulin resistance have been found to play important roles in DCM pathophysiology.

Recent research has shown that miRNAs are involved in processes such as myocardial cell proliferation, differentiation, and metastasis, and promote the progression of DCM. Despite these insights, the regulatory effects of miRNAs on immune function in DCM remain inadequately explored.
