Aims/Background Research evidence has demonstrated a significant association between hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF), but the causality and pattern of this link remain unexplored. Therefore, this study investigated the causal relationship between HCM and AF using a two-sample and bidirectional Mendelian randomization (MR) approach. Additionally, this assessed the role of cardiovascular proteins (CPs) associated with cardiovascular diseases between HCM and AF by applying a two-step MR analysis. ⋯ Moreover, Two-step MR analyses indicated that 5 CPs were causally associated with HCM; 12 CPs with AF and 1 CP (Melusin) with both HCM and AF. Additionally, Melusin was observed as a protective factor for both HCM and AF and may serve as a mediator variable for these two conditions (mediation effect 0.0004, mediation ratio 5.5178%, 95% CI: 5.4624-5.5731). Conclusion HCM may increase the risk of developing AF, with Melusin serving as a mediator for this risk.

Randomized Controlled Trial
Efficacy of General Magnetic Therapy and Motor-Evoked Potential-Guided Precision Magnetic Therapy in Patients with Overactive Bladder: A Randomized Controlled Trial.
Aims/Background Overactive bladder (OAB) is a prevalent chronic condition affecting approximately 12% of adults, with incidence increasing with age. While pharmacological and behavioural therapies are standard treatments, their efficacy is often limited by side effects and poor adherence. This study aimed to compare the therapeutic effects of precision magnetic stimulation guided by motor-evoked potential with general magnetic therapy in patients with OAB. ⋯ While there were no significant differences between the two magnetic stimulation methods in terms of OABSS scores, urgent urination, nocturnal urination, or maximum bladder volume, precision magnetic therapy showed greater efficacy in reducing urination frequency and improving initial bladder volume. These findings suggest that precision magnetic therapy offers an enhanced therapeutic benefit. Clinical Trial Registration Chinese Clinical Trial Registry (ChiCTR2400087888).

The burdens of cardiovascular (CV) diseases and cardiotoxic side effects of cancer treatment in oncology patients are increasing in parallel. The European Society of Cardiology (ESC) 2022 Cardio-Oncology guidelines recommend the use of standardized risk stratification tools to determine the risk of cardiotoxicity associated with different anticancer treatment modalities and the severity of their complications. The use of the Heart Failure Association-International Cardio-Oncology Society (HFA-ICOS) is essential for assessing risk prior to starting cancer treatment, and validation of these methods has been performed in patients receiving anthracyclines, human epidermal receptor 2 (HER2)-targeted therapies and breakpoint cluster region-abelson oncogene locus (BCR-ABL) inhibitors. ⋯ This review summarizes the key points of risk stratification in these patients. The steps include identifying the target population, assessing nonmodifiable and modifiable CV risk factors, reviewing previous oncologic therapies and CV histories, and performing baseline investigations. In summary, this review aims to provide general physicians with a simple 7-step guide that will help steer and navigate them through cardiac risk evaluation of potentially cardiotoxic oncologic treatment strategies.

Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are commonly prescribed in diabetes mellitus and increasingly for cardiorenal protection. They carry the risk of euglycaemic diabetic ketoacidosis (eDKA). Guidelines around the perioperative handling of these medications are limited and some evidence suggests that withholding them can lead to more surgical complications and poorer glycaemic control. This article gives an overview of arguments for and against withholding SGLT-2 inhibitors in the perioperative period.

Aims/Background The relationship between retinal fundus hemorrhage and the severity of coronary artery lesions remains unclear. This study aimed to explore the incidence of fundus hemorrhage in patients at high risk of coronary heart disease (CHD) and to examine its correlation with the SYNTAX score, a tool used to assess the complexity of coronary artery disease. Methods This retrospective study consecutively enrolled patients undergoing coronary angiography (CAG) at Beijing Anzhen Hospital Hospital from June 2019 to January 2020. ⋯ The incidence of fundus hemorrhage was significantly higher in the hSS group compared to the lSS group (21.47% [38/177] vs. 7.56% [53/701], p < 0.001). Multivariate logistic regression analysis identified fundus hemorrhage, body mass index (BMI), and low-density lipoprotein cholesterol (LDL-C) as independent predictors of high SYNTAX scores. Conclusion Fundus hemorrhage is significantly associated with a higher SYNTAX score and may serve as a potential predictor of severe coronary artery lesions in clinical practice.
