Impact of renal impairment on atrial fibrillation: ESC-EHRA EORP-AF Long-Term General Registry

Background: Atrial fibrillation (AF) and renal impairment share a bidirectional relationship with important pathophysiological interactions. We evaluated the impact of renal impairment in a contemporary cohort of patients with AF. Methods: We utilised the ESC-EHRA EORP-AF Long-Term General Registry. Outcomes were analysed according to renal function by CKD-EPI equation. The primary endpoint was a composite of thromboembolism, major bleeding, acute coronary syndrome and all-cause death. Secondary endpoints were each of these separately including ischaemic stroke, haemorrhagic event, intracranial haemorrhage, cardiovascular death and hospital admission. Results: A total of 9306 patients were included. The distribution of patients with no, mild, moderate and severe renal impairment at baseline were 16.9%, 49.3%, 30% and 3.8%, respectively. AF patients with impaired renal function were older, more likely to be females, had worse cardiac imaging parameters and multiple comorbidities. Among patients with an indication for anticoagulation, prescription of these agents was reduced in those with severe renal impairment, p <.001. Over 24 months, impaired renal function was associated with significantly greater incidence of the primary composite outcome and all secondary outcomes. Multivariable Cox regression analysis demonstrated an inverse relationship between eGFR and the primary outcome (HR 1.07 [95% CI, 1.01–1.14] per 10 ml/min/1.73 m2 decrease), that was most notable in patients with eGFR <30 ml/min/1.73 m2 (HR 2.21 [95% CI, 1.23–3.99] compared to eGFR ≥90 ml/min/1.73 m2). Conclusion: A significant proportion of patients with AF suffer from concomitant renal impairment which impacts their overall management. Furthermore, renal impairment is an independent predictor of major adverse events including thromboembolism, major bleeding, acute coronary syndrome and all-cause death in patients with AF

Cardiopoietic cell therapy for advanced ischemic heart failure: results at 39 weeks of the prospective, randomized, double blind, sham-controlled CHART-1 clinical trial

Cardiopoietic cells, produced through cardiogenic conditioning of patients' mesenchymal stem cells, have shown preliminary efficacy. The Congestive Heart Failure Cardiopoietic Regenerative Therapy (CHART-1) trial aimed to validate cardiopoiesis-based biotherapy in a larger heart failure cohort

P2758Role of echocardiographic findings and blood culture in embolic complications in patients with infective endocarditis

Abstract Echocardiography is essential for the diagnosis of infective endocarditis (IE), treatment choice and follow-up. Prognosis in IE is multifactorial and includes both structural changes of the heart induced by IE and extra-cardiac IE complications. Aims Aims of the study were to analyse: 1) relation between embolic complications of IE and structural changes of the heart detected by echocardiography in IE patients; 2) association between embolic complications of IE and IE causative microorganism. Methods 335 patients with definitive IE from the single tertiary center were enrolled in the study between 2009–2018. Echocardiographic changes are defined in accordance with 2015 ESC guideline. Associations between embolic complication and structural heart changes, as well as between IE causative microorganism and embolic complications were tested by Chi square test. Results Observed embolic complication were: ischemic stroke (in 12.5% of patients), haemorrhagic stroke (2.1%), neuroinfection (9.6%), brain abscess (1.8%), discitis (3%), pulmonary embolism (1.5%), spleen abscess (7.8%) and peripheral arterial embolization (1.5%). There were several significance associations: vegetations larger than 15 mm were associated with ischemic stroke (p=0.041) and peripheral arterial embolization (p=0.05); perivalvular abscess was associated with brain abscess (p=0.037) and peripheral arterial embolization (p=0.019). Staphylococcus aureus isolated from blood cultures was associated with discitis (p&lt;0.001), brain abscess (p&lt;0.001) and neuroinfection (p&lt;0.001). Bacterias from HACEK group were associated with peripheral arterial embolisation (p&lt;0.001) and non-HACEK bacterias were associated with ichemic stroke (p=0.016). Patients with more than one isolated bacteria from blood culture had more often spleen abscess (p=0.003) and ichemic stroke (p=0.049). Conclusion Results point that large vegetations, but also perivalvular abscesses are coupled with higher rate of embolic complications in patients with IE. Staphylococcus aureus, HACEK group and non-HACEK bacteria are, more than other causative IE microorganisms, associated with embolism. These results might be clinically important for treatment chose and prognosis of the patients with IE. </jats:sec
