Summary: Congenital long QT syndrome is a hereditary cardiovascular disorder characterized by prolonged QT interval. This study demonstrates the effectiveness of using patient-specific iPSCs to identify potential cures and alternative therapies for long QT syndrome patients who do not respond well to conventional treatments. Verapamil and lidocaine show promise as therapeutic agents in reducing symptoms and improving the quality of life for these patients.

Summary: In the past decade, personalized medicine has made significant progress in addressing patient-specific disease complexities and developing individualized treatment strategies. The emergence of 3D bioprinting has provided novel opportunities for personalized medicine, although current bioprinted constructs have limitations in achieving anatomically realistic organs with mature biological functions. This review discusses the principles and realizations of bioprinting, focusing on techniques such as extrusion printing and digital light processing (DLP). It also explores the applications of bioprinted constructs in regenerative medicine and drug discovery. Despite the challenges, bioprinting shows promise as an empowering technology to overcome critical obstacles in personalized medicine.

Summary: The current healthcare system is limited by the concept of one size fits all, resulting in varied responses and adverse reactions in patients. Personalized medicine (PM) offers customized therapy for individual patients, potentially revolutionizing the healthcare system. 3D printing techniques can be used to design PM in metabolic syndrome, delivering the desired dose and drug release profile for optimal efficacy and safety.

Summary: During the early stages of the COVID-19 pandemic, the use of drug repurposing to find compounds for improving the prognosis of symptomatic patients was common. Hydroxychloroquine (HCQ) was one of the first drugs used for COVID-19 treatment, but its effectiveness is debated and it may cause electrocardiographic abnormalities. By studying human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), researchers found that HCQ had proarrhythmic effects and could potentially distinguish symptomatic from asymptomatic mutation carriers.

Summary: This research established an effective three-dimensional culture system for generating kidney cancer organoids and successfully generated 33 organoid lines from different subtypes of kidney cancer. These organoids preserved the histological architecture, mutational landscape, and transcriptional profile of the parental tumor tissues, and revealed inter- and intra-tumoral heterogeneity. Additionally, the organoids can be used for drug screening and evaluating the efficacy of immunotherapy.

The generated cells showed similar secretory responsiveness as human pituitary cells in vivo. This model could be used in various studies such as drug discovery, prediction of side effects, and elucidation of tumorigenic mechanisms. Furthermore, it may contribute to the development of regenerative medicine for the pituitary gland.

Summary: A recent randomized trial showed that catheter ablation for atrial fibrillation (AF) in heart failure patients with reduced ejection fraction (EF) can reduce the risk of death or heart failure. However, the effectiveness of catheter ablation for AF in heart failure patients with mid-range or preserved EF remains uncertain.

Summary: This study aims to capture the cardiopulmonary complexity of patients with mitral regurgitation (MR) using a machine-learning (ML)-based phenotyping approach. The study found considerable heterogeneity in cardiac damage among MR patients depending on underlying factors and comorbidities. The ML model identified four phenotypes and correlated them with 5-year outcomes.

Summary: This study found that BNP and NT-proBNP levels change over time during hospitalization for AHF, with BNP significantly decreasing on Days 2-5 and Before-discharge, while NT-proBNP remains unchanged. The research also revealed that a high NT-proBNP/BNP ratio on Day 2-5 is associated with poorer prognosis, even if BNP levels adequately decrease.

Summary: A 77-year-old female presented with loss of consciousness, hypotension, and bradycardia. She had elevated Trop-T and lactate levels, indicating an infero-posterior ST elevation myocardial infarction. Echocardiography revealed a reduced left ventricular ejection fraction, abnormal wall motion in the infero-posterior region, hyperkinetic apical movement, and severe mitral regurgitation. Coronary angiography showed a hypoplastic right coronary artery, total thrombotic occlusion of the dominant left circumflex artery, and 75% stenosis in the left anterior descending artery. Hemodynamic improvement and reduction of acute ischemic mitral regurgitation were achieved with the use of Impella 2.5 and successful percutaneous coronary intervention with stents. The patient underwent staged PCI to the left anterior descending artery and was discharged after completion.

Summary: Patients with life-threatening acute myocardial infarction (AMI) are transferred to either emergency medical care center (EMCC) or cardiovascular intensive care unit (CICU). The EMCC group had more severe disease, longer door-to-reperfusion time, and higher in-hospital mortality rates, especially from non-cardiac causes, compared to the CICU group. Additionally, the EMCC group had a significantly higher 1-year post-discharge mortality rate than the CICU group.

Summary: This study aimed to compare the incidence of intracranial hemorrhage (ICH) and ischemic stroke in elderly patients with nonvalvular atrial fibrillation (NVAF) taking direct oral anticoagulants (DOACs) versus warfarin in a real-world setting. The results showed that patients on DOACs had lower risks of ischemic stroke, ICH, and subdural/epidural hemorrhage compared to those on warfarin.

Summary: There were limited clinical studies on the relationship between SGLT2 inhibitors and hematopoiesis in patients with diabetes and heart failure. In the CANDLE trial, 226 patients were studied, and it was found that canagliflozin was associated with increased hematocrit and hemoglobin levels compared to glimepiride. In conclusion, canagliflozin improved hematologic parameters in patients with diabetes and heart failure.

Summary: This study used next-generation sequencing to analyze the genes of a familial case with complex congenital heart disease (CHD). Two rare variants in the NODAL and TBX20 genes were identified and found to affect downstream signaling pathways involved in heart development. These findings suggest that loss-of-function mutations in NODAL and TBX20 may contribute to the etiology of complex CHD associated with single ventricle defects in this family.

Summary: This sub-analysis of the ANAFIE Registry investigated 2-year outcomes and oral anticoagulant use stratified by glycated hemoglobin (HbA1c) levels among Japanese patients aged ≥ 75 years with non-valvular atrial fibrillation (NVAF) with and without clinical diagnosis of diabetes mellitus (DM). The results showed that only HbA1c ≥ 8.0% was associated with increased all-cause death and net clinical outcome risks, while the event risks did not increase in other HbA1c subgroups.

Summary: This sub-cohort study aimed to estimate the incidence of clinical outcomes in elderly Japanese patients with non-valvular atrial fibrillation (NVAF) and high home systolic blood pressure (H-SBP) receiving anticoagulant therapy. The results showed that in warfarin-treated patients, the incidence of cardiovascular events was higher in those with H-SBP ≥ 145 mmHg compared to those with H-SBP < 125 mmHg. In the DOAC group, there was also a tendency for increased cardiovascular events at H-SBP ≥ 145 mmHg. Therefore, strict blood pressure control is necessary in elderly NVAF patients receiving anticoagulant therapy.

Summary: This study aimed to identify the preferred left ventricular (LV) lead position for upgrading conventional right ventricular (RV) apical pacing to cardiac resynchronization therapy (CRT). The results showed that the QRS duration decreased and the left ventricular dP/dt(max) increased at the LV anterolateral site compared to the posterolateral site during biventricular pacing compared with RV apical pacing. Therefore, the LV anterolateral site is the preferred LV lead position for upgrading RV apical pacing to CRT.

Summary: Understanding patient perspectives and the association with patient-physician communication is crucial for improving multidisciplinary education programs and adherence to self-care in heart failure patients. This study found that patients had high confidence in most self-care behaviors, except for low-salt diet, regular exercise, and flu vaccination. The quality of patient-physician communication was also found to be associated with patient confidence.
