Heart disease in cattle remains medically challenging both to diagnose and to treat. This is in part due to its low incidence in the bovine species but also because the prognosis is typically guarded to poor. The majority of published data concerning bovine heart disease are case studies and case reports. The aim of this article is to review the evidence-based medicine on the principal heart diseases of cattle (pericarditis, bacterial endocarditis, congenital heart defects, cor pulmonale, dilated cardiomyopathy and heart neoplasms), with emphasis on their diagnosis, prognosis and treatment.

Despite advancements in engineered heart tissue (EHT), challenges persist in achieving accurate dimensional accuracy of scaffolds and maturing human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), a primary source of functional cardiac cells. Drawing inspiration from cardiac muscle fiber arrangement, a three-dimensional (3D)-printed multi-layered microporous polycaprolactone (PCL) scaffold is created with interlayer angles set at 45° to replicate the precise structure of native cardiac tissue. Compared with the control group and 90° PCL scaffolds, the 45° PCL scaffolds exhibited superior biocompatibility for cell culture and improved hiPSC-CM maturation in calcium handling.

Pulmonary rehabilitation (PR) services are increasingly using alternative programme delivery modes, for example telerehabilitation strategies including videoconferencing, to improve patient choice and accessibility. Although telerehabilitation results in improvements in core outcomes, the effect on knowledge attainment is not known. To observe the real-world responses of patients choosing to undergo videoconference PR to a matched control group choosing to undergo in-person PR, in terms of knowledge attainment.

Background: Vascular calcification is a detrimental aging pathology markedly accelerated in patients with chronic kidney disease. Prelamin A is a biomarker of vascular smooth muscle cell aging that accelerates calcification however the mechanisms remain undefined.
Methods: Vascular smooth muscle cells were transduced with prelamin A using an adenoviral vector and epigenetic modifications were monitored using immunofluorescence and targeted polymerase chain reaction array.

Background: Despite fractional flow reserve (FFR)-guided deferral of revascularization, recurrent events in patients with diabetes or after myocardial infarction remain common. This study aimed to assess the association between FFR-negative but high-risk nonculprit lesions and clinical outcomes.
Methods: This is a patient-level pooled analysis of the prospective natural-history COMBINE (OCT-FFR) study (Optical Coherence Tomography Morphologic and Fractional Flow Reserve Assessment in Diabetes Mellitus Patients) and PECTUS-obs study (Identification of Risk Factors for Acute Coronary Events by OCT After STEMI and NSTEMI Patients With Residual Non- Flow Limiting Lesions).
