Artificial intelligence applied in identifying left ventricular walls in myocardial perfusion scintigraphy images: Pilot study.
PLoS One
January 2025
Electrical, Mechanical & Computer Engineering School, Federal University of Goias, Goiania, Brazil.
This paper proposes the use of artificial intelligence techniques, specifically the nnU-Net convolutional neural network, to improve the identification of left ventricular walls in images of myocardial perfusion scintigraphy, with the objective of improving the diagnosis and treatment of coronary artery disease. The methodology included data collection in a clinical environment, followed by data preparation and analysis using the 3D Slicer Platform for manual segmentation, and subsequently, the application of artificial intelligence models for automated segmentation, focusing on the efficiency of identifying the walls of the left ventricular. A total of 83 clinical routine exams were collected, each exam containing 50 slices, which is 4,150 images.

Department of Clinical Epidemiology, Graduate School of Medicine, Fukushima Medical University, Fukushima-city, Fukushima, Japan.
This study analyzed the association of romosozumab, a human monoclonal antibody with bone-forming and bone resorption-inhibiting effects, and bisphosphonates with the development of cardiovascular disease among patients with osteoporosis. A new-user design was employed to address selection bias, and instrumental variable analysis was used to address confounding by indication. Japanese patients aged ≥40 years, diagnosed with osteoporosis or experienced a fragility fracture, were admitted to medical facilities covered by a commercial administrative claims database, and newly prescribed romosozumab or bisphosphonates after the commercialization of romosozumab in Japan (March 4, 2019) were included based on verification of a 180-day washout period.

Eur J Heart Fail
January 2025
Department of Medicine, University of Chicago Medicine, Chicago, IL, USA.
Aims: This post hoc analysis aimed to assess the efficacy and safety of the non-steroidal mineralocorticoid receptor antagonist finerenone by baseline diuretic use in FIDELITY, a pre-specified pooled analysis of the phase III trials FIDELIO-DKD and FIGARO-DKD.
Methods And Results: Eligible patients with type 2 diabetes (T2D) and chronic kidney disease (CKD; urine albumin-to-creatinine ratio [UACR] ≥30-<300 mg/g and estimated glomerular filtration rate [eGFR] ≥25-≤90 ml/min/1.73 m, or UACR ≥300-≤5000 mg/g and eGFR ≥25 ml/min/1.
Metabolic cardiomyopathy associated with a compound heterozygous variant in NAD(P)HX dehydratase: a case report and literature review.

Department of Pediatric Intensive Care Unit, National Regional Medical Center, Guizhou Branch of Shanghai Children's Medical Center, School of Medicine, Shanghai Jiao Tong University, Guizhou Provincial People's Hospital, Guiyang, China.
Background: Metabolic cardiomyopathy is characterized by structural and functional changes to the heart and interstitial fibrosis without coronary artery disease or hypertension. Inborn metabolic defects are a common cause of cardiomyopathy in children. There are more than 40 kinds of inborn metabolic defects that cause cardiomyopathy.

CTVS Department, AIIMS Rishikesh, Rishikesh, 249203 India.
Unlabelled: Testing methods of detecting various cardiac biomarkers play a significant influence in determining and treating cardiac-related conditions and ultimate prognosis. With the increasing global prevalence of cardiac disease, the importance of rapid testing methods in diagnosis and management has grown tremendously. The point-of-care testing (POCT) method is a potential biochemical diagnostic technique that may overcome the issue of delayed laboratory results, particularly in regions with limited access to advanced laboratory equipment or resource-constrained.
