Laboratory Grown Biofilms of Bacteria Associated with Human Atherosclerotic Carotid Arteries Release Collagenases and Gelatinases during Iron-Induced Dispersion
This study shows that plaque-associated bacteria, when cultured as mixed-species biofilms in the laboratory, can release degradative enzymes into their environment as the result of a dispersion response triggered by iron. These degradative enzymes can digest proteins and lipids which are associated with the tissues that separate the plaque lesion from the arterial lumen. Thus, this study demonstrates that if mixed species biofilms are induced to undergo dispersion in an infected atherosclerotic lesion when exposed to an elevated concentration of free iron, they have the potential to contribute to the weakening of arterial ...

Evolutionary cardiology and experimental research
Arch Cardiol Mex. 2022 May 10. doi: 10.24875/ACM.210002751. Online ahead of print.ABSTRACTEvolutionary medicine studies the role of evolution in health problems. Diseases are considered as phenotypes generated by the expression of sets of genes and a complex interplay with the environment. The main mechanisms involved in evolutionary medicine are antagonistic pleiotropy, ecological antagonistic pleiotropy, atavisms and heterochrony. Antagonistic pleiotropism refers to genes that are beneficial during certain stages of development but become detrimental in others. Ecological antagonistic pleiotropy refers to the misadaptati...

Po-661-07 a photoplethymography-based approach to atrial fibrillation-burden estimation in high-risk patients
Atrial fibrillation (AF) is the most common arrhythmia leading to hospital admission. Its incidence is linked to increased risk of stroke, congestive heart failure, and overall mortality. AF burden is a key determinant of outcomes, but accurate quantification can be limited by the cardiac monitoring period (typically days). Alternatively, longer-term monitoring comes at higher cost and often requires an invasive approach. The introduction of reliable wrist-worn devices may improve access to long-term monitoring of AF burden.

Use of TIMI Risk Index as a Simple and Valuable Prognostic Tool in Patients with ST-Segment Elevation Myocardial Infarction Who Underwent Primary Percutaneous Coronary Intervention
CONCLUSION: The results of this study indicated that Thrombolysis in Myocardial Infarction Risk Index value is an independent predictor of clinical outcomes such as death and heart failure but not subsequent myocardial infarction in ST-segment elevation myocardial infarction patients. The use of Thrombolysis in Myocardial Infarction Risk Index can be considered in ST-segment elevation myocardial infarction patients who underwent primary percutaneous coronary intervention as it is an easily applicable and important indicator of prognosis.PMID:35450843 | DOI:10.5152/tkda.2022.21143
