Although this association is well-established, the factors inducing and accelerating cognitive decline beyond ageing and the intricate causal pathways and multilateral interdependencies involved remain poorly understood. Dysregulated and persistent inflammatory processes have been implicated as potentially causal mediators of the adverse consequences on brain function in patients with cardiac disease. Recent advances in positron emission tomography disclosed an enhanced level of neuroinflammation of cortical and subcortical brain regions as an important correlate of altered cognition in these patients. In preclinical and clinical investigations, the thereby involved domains and cell types of the brain are gradually better characterized. Microglia, resident myeloid cells of the central nervous system, appear to be of particular importance, as they are extremely sensitive to even subtle pathological alterations affecting their complex interplay with neighboring astrocytes, oligodendrocytes, infiltrating myeloid cells, and lymphocytes. Here, we review the current evidence linking cognitive impairment and chronic neuroinflammation in patients with various selected cardiac disorders including the aspect of chronic neuroinflammation as a potentially druggable target.}, language = {en} } @article{RadakovicPenovLazarusetal.2023, author = {Radakovic, Dejan and Penov, Kiril and Lazarus, Marc and Madrahimov, Nodir and Hamouda, Khaled and Schimmer, Christoph and Leyh, Rainer G. and Bening, Constanze}, title = {The completeness of the left atrial appendage amputation during routine cardiac surgery}, series = {BMC Cardiovascular Disorders}, volume = {23}, journal = {BMC Cardiovascular Disorders}, doi = {10.1186/s12872-023-03330-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-357376}, year = {2023}, abstract = {Background Left atrial appendage (LAA) is the origin of most heart thrombi which can lead to stroke or other cerebrovascular event in patients with non-valvular atrial fibrillation (AF). This study aimed to prove safety and low complication rate of surgical LAA amputation using cut and sew technique with control of its effectiveness. Methods 303 patients who have undergone selective LAA amputation were enrolled in the study in a period from 10/17 to 08/20. The LAA amputation was performed concomitant to routine cardiac surgery on cardiopulmonary bypass with cardiac arrest with or without previous history of AF. The operative and clinical data were evaluated. Extent of LAA amputation was examined intraoperatively by transoesophageal echocardiography (TEE). Six months in follow up, the patients were controlled regarding clinical status and episodes of strokes. Results Average age of study population was 69.9 ± 19.2 and 81.9\% of patients were male. In only three patients was residual stump after LAA amputation larger than 1 cm with average stump size 0.28 ± 0.34 cm. 3 patients (1\%) developed postoperative bleeding. Postoperatively 77 (25.4\%) patients developed postoperative AF (POAF), of which 29 (9.6\%) still had AF at discharge. On 6 months follow up only 5 patients had NYHA class III and 1 NYHA class IV. Seven patients reported with leg oedema and no patient experienced any cerebrovascular event in early postoperative follow up. Conclusion LAA amputation can be performed safely and completely leaving minimal to no LAA residual stump.}, language = {en} } @article{DoehlerRoederSchlesingeretal.2023, author = {D{\"o}hler, Ida and R{\"o}der, Daniel and Schlesinger, Tobias and Nassen, Christian Alexander and Germer, Christoph-Thomas and Wiegering, Armin and Lock, Johan Friso}, title = {Risk-adjusted perioperative bridging anticoagulation reduces bleeding complications without increasing thromboembolic events in general and visceral surgery}, series = {BMC Anesthesiology}, volume = {23}, journal = {BMC Anesthesiology}, doi = {10.1186/s12871-023-02017-z}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-357305}, year = {2023}, abstract = {Background Perioperative bridging of oral anticoagulation increases the risk of bleeding complications after elective general and visceral surgery. The aim of this study was to explore, whether an individual risk-adjusted bridging regimen can reduce bleeding events, while still protecting against thromboembolic events. Methods We performed a quality improvement study comparing bridging parameters and postoperative outcomes before (period 1) and after implementation (period 2) of a new risk-adjusted bridging regimen. The primary endpoint of the study was overall incidence of postoperative bleeding complications during 30 days postoperatively. Secondary endpoints were major postoperative bleeding, minor bleeding, thromboembolic events, postoperative red blood cell transfusion, perioperative length-of-stay (LOS) and in-hospital mortality. Results A total of 263 patients during period 1 and 271 patients during period 2 were compared. The included elective operations covered the entire field of general and visceral surgery. The overall incidence of bleeding complications declined from 22.1\% during period 1 to 10.3\% in period 2 (p < 0.001). This reduction affected both major as well as minor bleeding events (8.4\% vs. 4.1\%; p = 0.039; 13.7\% vs. 6.3\%; p = 0.004). The incidence of thromboembolic events remained low (0.8\% vs. 1.1\%). No changes in mortality or length-of-stay were observed. Conclusion It is important to balance the individual thromboembolic and bleeding risks in perioperative bridging management. The risk adjusted bridging regimen reduces bleeding events in general and visceral surgery while the risk of thromboembolism remains comparably low.}, language = {en} }
