Does heparin rebound lead to postoperative blood loss in patients undergoing cardiac surgery with cardiopulmonary bypass?
CONCLUSION: The influence of heparin rebound on postoperative bleeding seems to be negligible, but might get significant in conjunction with incomplete heparin reversal or other coagulopathies. For that reason, it might be useful to get a picture of the entire coagulation spectrum after cardiac surgery, as can be done by the use of a viscoelastic test in conjunction with an aggregometry test.PMID:37734336 | DOI:10.1177/02676591231199218

Role of toll-like receptor-mediated pyroptosis in sepsis-induced cardiomyopathy
Biomed Pharmacother. 2023 Sep 19;167:115493. doi: 10.1016/j.biopha.2023.115493. Online ahead of print.ABSTRACTSepsis, a life-threatening dysregulated status of the host response to infection, can cause multiorgan dysfunction and mortality. Sepsis places a heavy burden on the cardiovascular system due to the pathological imbalance of hyperinflammation and immune suppression. Myocardial injury and cardiac dysfunction caused by the aberrant host responses to pathogens can lead to cardiomyopathy, one of the most critical complications of sepsis. However, many questions about the specific mechanisms and characteristics of this ...

Multiscale Structure and Function of the Aortic Valve Apparatus
Physiol Rev. 2023 Sep 21. doi: 10.1152/physrev.00038.2022. Online ahead of print.ABSTRACTWhile studying the aortic valve in isolation has facilitated the development of life-saving procedures and technologies, the dynamic interplay of the aortic valve and its surrounding structures is vital to preserving their function across the wide range of conditions encountered in an active lifestyle. Our view is that these structures should be viewed as an integrated functional unit, herein referred to as the aortic valve apparatus (AVA). The coupling of the aortic valve and root, left ventricular outflow tract, and blood circulation...

Microvascular dysfunction in women with a history of hypertensive disorders of pregnancy: A population-based retrospective cohort study
CONCLUSIONS: The findings reveal microvascular dysfunction at long-term follow up in women with previous pre-eclampsia and strengthen the possible role of endothelial dysfunction as a link to the increased risk of cardiovascular disease in women with HDP.PMID:37732494 | DOI:10.1111/1471-0528.17665

Hyperpolarized 1- < sup > 13 < /sup > Cpyruvate Magnetic Resonance Spectroscopy Shows That Agmatine Increased Lactate Production in the Brain of Type 2 Diabetic Mice
CONCLUSION: Agmatine influences the NADH/NAD+ redox state in the brains of T2DM mice, which may be connected with enhanced cognitive performance and increased conversion of HP [1-13C]pyruvate to HP [1-13C]lactate.PMID:37727922 | DOI:10.3349/ymj.2022.0554

Three-dimensional electrical impedance tomography (EIT) to study regional ventilation/perfusion (V/Q ̇) ratios in anesthetized pigs
This study aimed to develop a 3D method for assessing ventilation/perfusion (V/Q̇) ratios in a pig model of hemodynamic perturbations using electrical impedance tomography (EIT). In order to evaluate the physiological coherence of changes in EIT-derived V/Q̇ ratios, global EIT-derived V/Q̇ mismatches were compared with global gold-standards. The study found regional heterogeneity in the distribution of V/Q̇ ratios in both the ventrodorsal and craniocaudal directions. Although global EIT-derived indices of V/Q̇ mismatch consistently underestimated both low and high V/Q̇ mismatch compared to global gold standards, the ...
