Atherosclerosis is the underlying cause of most cardiovascular-related deaths in industrialized nations. Determining the etiology of atherosclerosis and detecting lesions in the early stages of the disease for possible pharmacological or mechanical intervention have been challenges facing cardiovascular researchers. In addition to genetic and environmental factors, the formation and growth of atheroma have been linked to the complex fluid dynamics and mass transport in these arterial segments. This article reviews the current state of affairs in imaging modalities and image processing techniques that allow the visualization and morphologically realistic reconstruction of coronary arterial geometry to aid in the diagnosis and treatment of coronary artery disease (CAD). In addition, studies pertaining to our current understanding of the complex flow dynamics in the coronary arteries and the relationship between fluid-induced stresses on the initiation and growth of the atherosclerotic lesions are also reviewed. The article concludes with a brief discussion on possible future directions of research that will advance our knowledge of this challenging problem.

Left bundle branch pacing (LBBP) is an emerging physiological pacing technique characterized by stable pacing parameters and a narrower QRS duration. This study aims to compare the long-term efficacy and safety of biventricular pacing (BIVP) and LBBP in patients with heart failure with reduced ejection fraction (HFrEF) and complete left bundle branch block (CLBBB). A retrospective analysis was conducted on 35 patients with chronic HFrEF accompanied by CLBBB treated at our center from April 2018 to October 2022.

Angina pectoris (AP), a clinical syndrome characterized by paroxysmal chest pain, is caused by insufficient blood supply to the coronary arteries and sudden temporary myocardial ischemia and hypoxia. Long-term AP typically induces other cardiovascular events, including myocardial infarction and heart failure, posing a serious threat to patient safety. However, AP's complex pathological mechanisms and developmental processes introduce significant challenges in the rapid diagnosis and accurate treatment of its different subtypes, including stable angina pectoris (SAP), unstable angina pectoris (UAP), and variant angina pectoris (VAP).

Background: Prior studies have demonstrated an association between retinal vascular features and cardiovascular disease (CVD), however most studies have only evaluated a few simple parameters at a time. Our aim was to determine whether a deep-learning artificial intelligence (AI) model could be used to predict CVD outcomes from routinely obtained diabetic retinal screening photographs and to compare its performance to a traditional clinical CVD risk score.
Methods: We included 6127 individuals with type 2 diabetes without myocardial infarction or stroke prior to study entry.

Evidence has argued about the association between dairy intake and premature coronary artery disease (PCAD) development aimed to be discussed in this study. This case-control study was conducted on 813 individuals with PCAD and 471 healthy controls. The dairy intake of participants was assessed by a validated semi-quantitative food frequency questionnaire.

However, lack of large sample size studies and methods to link adverse haemodynamics to anatomical information has hindered meaningful insights to date. The Left Main coronary bifurcations of 127 patients with suspected coronary artery disease in the absence of significant stenosis were segmented from CTCA images before computing the local haemodynamics.
