TY - THES A1 - Stefenelli, Ulrich T1 - Der „Würzburger Herz-Score“, ein Modell zur tageweisen Vorhersage des Sterberisikos in den ersten 4 Wochen nach Herzklappen- oder Bypass-Operation bei 5555 Patienten T1 - The Wuerzburg Heart-Score, a model to predict the mortality risk (daily ) in the first 4 weeks after heart valve or bypass surgery in 5555 patients N2 - Bei 5555 Patienten des Würzburger Zentrums für operative Medizin wurden Sterberisiken und assoziierte Faktoren nach Bypass- oder Aortenklappen-OP beschrieben. Eine Risikovorhersage war frühzeitig, sogar tageweise möglich, und nicht (wie bisher) mit Blick auf den 30. postoperativen Tag. Das stärkste Risiko ist ein fehlender Entlassungs-Sinusrhythmus, gefolgt von einer schweren präoperativen Einschränkung (ASA) und einem erhöhten Kreatinin, gefolgt vom kardiogenen anamnestischen Schock, vom zerebrovaskulären Ereignis, der Notwendigkeit von Frischplasma, von einer respiratorischen Insuffizienz, aber auch der Notwendigkeit mechanischer Kreislaufunterstützung. Hochprädiktiv war auch ein kürzlich stattgefundener Myokardinfarkt und eine Angina Pectoris in Ruhe. Liegen bis 4 dieser Ereignisse vor, so zeigt sich das Mortalitätsrisiko als statistisch normal (Verlauf der Grundgesamtheit): Es steigt je Woche nach OP um etwa 1% auf rund 5% nach 4 Wochen an. Bestehen 5 oder 6 Risiken, so erhöht sich das Sterberisiko deutlich: Es steigt um +10% je weitere Woche an und erreicht etwa 40% in der 4. postoperativen Woche. Ab 7 oder mehr erfüllte Risiken nimmt das Sterberisiko drastisch zu. Es erhöht sich um +20% je weitere Woche und kumuliert nach 3 Wochen auf rund 70%. Festzuhalten ist: Bis 4 Risiken ergibt sich je weitere Woche +1% Mortalitätsrisiko, ab 5 Risikofaktoren +10%, ab 7 und mehr Risikofaktoren finden sich je Woche nach der OP ein um +20% erhöhtes Sterberisiko. Diese Erkenntnisse wurden verwendet, um einen Risikoscore zu konstruieren. Die Einzelrisiken werden summiert, d.h. man betrachtet das Risiko als erfüllt oder nicht, und zählt. Das tageweise Risiko ist graphisch ablesbar und ist für die klinische Routine verwendbar, für Studien (Risikostratifizierung) oder für das präoperative Aufklärungsgespräch. Neu ist, dass dieser Score im klinischen Verlauf angepaßt werden kann, wenn neue Risikofaktoren auftreten hinzukommen oder Faktoren therapiebedingt wegfallen. N2 - Mortality risks and associated factors after bypass or aortic valve surgery were described in 5555 patients at the Würzburg Center for Operative Medicine. A risk prediction was possible at an early stage, even on a daily basis, and not - as before - only with a view to the 30th postoperative day. The greatest risk is an absent discharge sinus rhythm, followed by severe impairment (ASA) and elevated creatinine, followed by a history of cardiogenic shock, cerebrovascular event, the need for fresh plasma, respiratory failure, but also the need for mechanical circulatory support . A recent history of myocardial infarction and angina pectoris at rest were also highly predictive. If up to 4 of these events are present, the mortality risk is statistically normal, because it roughly corresponds to the course of the population: it increases by around 1% per postoperative week to around 5% after 4 weeks (+ 2nd % as confidence range). If the patient has 5 or 6 risks, the risk of death increases significantly: it increases by +10% for each additional week and reaches about 40% in the 4th postoperative week. From 7 or more risk factors fulfilled, the risk of death increases drastically. It increases by +20% for each additional postoperative week and accumulates to around 70% (+ 15%) after 3 weeks of intensive care. It should be noted: Up to 4 risk factors result in a +1% mortality risk for each additional week, from 5 risk factors +10%, from 7 and more risk factors there is a +20% increased risk of death per week after the operation. Findings from this work were used to construct a risk score. The individual risks mentioned above are added up, i.e. the risk is considered to be fulfilled or not and counted. The daily risk can then be read graphically. This could be used for clinical routine, for studies (risk stratification) or for preoperative informational discussions. What is also new is that this score can be adjusted in the clinical course if new risk factors are added or factors are removed.

In 2020, the German Society for Prevention&Rehabilitation and the German Society for Cardiology requested establishing dedicated ""HF training groups."" Here, we aimed to implement and evaluate the feasibility and safety of one of the first HF training groups in Germany. Methods Twelve patients (three women) with symptomatic HF (NYHA class II/III) and an ejection fraction ≤ 45% participated and were offered weekly, physician-supervised exercise training for 1 year. Patients received a wrist-worn pedometer (M430 Polar) and underwent the following assessments at baseline and after 4, 8 and 12 months: cardiopulmonary exercise test, 6-min walk test, echocardiography (blinded reading), and quality of life assessment (Kansas City Cardiomyopathy Questionnaire, KCCQ). Results All patients (median age [quartiles] 64 [49; 64] years) completed the study and participated in 76% of the offered 36 training sessions. The pedometer was worn ≥ 1000 min per day over 86% of the time. No cardiovascular events occurred during training. Across 12 months, NT-proBNP dropped from 986 pg/ml [455; 1937] to 483 pg/ml [247; 2322], and LVEF increased from 36% [29;41] to 41% [32;46]%, (p for trend = 0.01). We observed no changes in exercise capacity except for a subtle increase in peak VO2% predicted, from 66.5 [49; 77] to 67 [52; 78]; p for trend = 0.03. The physical function and social limitation domains of the KCCQ improved from 60 [54; 82] to 71 [58; 95, and from 63 [39; 83] to 78 [64; 92]; p for trend = 0.04 and = 0.01, respectively. Positive trends were further seen for the clinical and overall summary scores. Conclusion This pilot study showed that the implementation of a supervised HF-exercise program is feasible, safe, and has the potential to improve both quality of life and surrogate markers of HF severity. This first exercise experiment should facilitate the design of risk-adopted training programs for patients with HF.
