Distant embolisation in infective endocarditis: characteristics and outcomes.

BACKGROUND: Infective endocarditis is a severe and potentially lethal cardiac disease. Recognition of the clinical features of endocarditis, such as distant embolisation, and adequate treatment should be initiated promptly given the grim perspective of upcoming virulent pathogens. METHODS: We report on our registry-based experience with outcomes of consecutive patients with infective endocarditis with distant embolisation. We aimed to describe the patient characteristics of infective endocarditis complicated by distant organ embolisation and the safety aspects of continuing endocarditis treatment at home in these patients. RESULTS: From November 2018 through April 2022, 157 consecutive patients were diagnosed with infective endocarditis. Of them, 38 patients (24%) experienced distant embolisation, either in the cerebrum (n = 18), a visceral organ (n = 5), the lungs (n = 7) or the myocardium (n = 8). Pathogens identified in blood cultures were predominantly streptococcal variants (43%), with only one culture-negative endocarditis case. Of the 18 patients with cerebral embolisation, 12 had neurological complaints and most often discrete abnormal findings on neurological examination. Six of the 8 cardiac embolism patients experienced chest pain before admission. Visceral organ and pulmonary embolism occurred silently. Of the 38 patients with distant embolisation, 17 could be discharged earlier by providing antibiotic treatment at home without complications. CONCLUSION: This registry-based single-centre experience showed an incidence of distant embolisation in daily care of 24%. Cerebral and coronary embolisation provoked symptoms, while visceral emboli remained silent. Pulmonary emboli may present with inflammatory signs. Distant embolisation was not in itself a contra-indication for outpatient endocarditis@home treatment.

Dataset on blood biomarkers and GRACE score measured at admission for myocardial infarction in a large secondary hospital.

The GRACE score is currently the most widely used model to assess patient prognosis after myocardial infarction (MI). We have demonstrated that the prognostic performance of the GRACE score can be improved by adding blood biomarkers measured routinely at hospital admission in our study recently published in the International Journal of Cardiology: "Addition of routinely measured blood biomarkers significantly improves GRACE risk stratification in patients with myocardial infarction". In this Data-in-Brief article we present additional original data from our dataset. This dataset consists of clinical and biomarker information and follow-up data of 2055 confirmed MI patients. In 143 of these patients the endpoint (all-cause mortality or reMI) occurred during six months follow-up. We describe the differences in baseline characteristics between ST-elevation MI (STEMI) patients and non-STEMI patients, differences in biomarker levels at admission between patients in whom the endpoint occurred and patients who remained endpoint-free, and associations of the biomarkers with the endpoint. Moreover, we show additional statistical results of analyses that compare the original GRACE-only model with our extended GRACE/biomarker model.

Call-to-balloon time dashboard in patients with ST-segment elevation myocardial infarction results in significant improvement in the logistic chain.

AIMS: Timely reperfusion with primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) patients is associated with superior clinical outcomes. Aiming to reduce ischaemic time, an innovative system for home-to-hospital (H2H) time monitoring was implemented, which enabled real-time evaluation of ischaemic time intervals, regular feedback and improvements in the logistic chain. The objective of this study was to assess the results after implementation of the H2H dashboard for monitoring and evaluation of ischaemic time in STEMI patients. METHODS AND RESULTS: Ischaemic time in STEMI patients transported by emergency medical services (EMS) and treated with pPCI in the Noordwest Ziekenhuis, Alkmaar before (2008-2009; n=495) and after the implementation of the H2H dashboard (2011-2014; n=441) was compared. Median time intervals were significantly shorter in the H2H group (door-to-balloon time 32 [IQR 25-43] vs. 40 [IQR 28-55] minutes, p-value <0.001, FMC-to-balloon time 62 [IQR 52-75] vs. 80 [IQR 67-103] minutes, p-value <0.001, and treatment delay 142 [IQR 103-221] vs. 159 [IQR 123-253] minutes, p-value <0.001). The H2H time dashboard was independently associated with shorter time delays. CONCLUSIONS: Real-time monitoring and feedback on time delay with the H2H dashboard improves the logistic chain in STEMI patients, resulting in shorter ischaemic time intervals.
