- Brief Summary
Chronic heart failure affects up to three million people in Germany, with prevalence increasing with age. It is a leading cause of cardiovascular disease-related deaths. Patients with heart failure undergoing non-cardiac surgery face higher risks of complications and death compared to those with coronary artery disease. Despite guidelines recommending comprehensive preoperative evaluation, there is no systematic risk assessment structure in place, leading to inadequate perioperative care. This study aims to evaluate a multidisciplinary approach for high-risk patients aged 65 and above, regardless of prior heart failure diagnosis, to mitigate postoperative complications. The investigators measure the NTpro BNP before surgery and include patients with NTproBNP\> 450 in this study and randomize them either to the standard care group or the intervention group.The hypothesis is that standardized risk screening and multidimensional care (Intervention group) can reduce complications in these patients undergoing non-cardiac surgery.
- Detailed Description
Currently, up to three million people in Germany suffer from chronic heart failure, with prevalence increasing with age. Chronic heart failure ranks among the most common cardiovascular diseases, leading to over 50,000 deaths annually. The proportion of older patients at risk of developing or already having heart failure undergoing non-cardiac surgical procedures is also rising. Studies from the USA indicate that patients with chronic heart failure face a higher risk of cardiac complications, including death, following non-cardiac surgeries compared to those with coronary heart disease. A significant proportion of deaths after non-cardiac surgeries are due to cardiac complications. In Europe, this translates to at least 167,000 cardiac complications annually from non-cardiac surgeries, with around 19,000 being life-threatening. Recent analysis suggests that preoperative elevation of NT-proBNP, a heart failure biomarker, is associated with a significantly increased risk of cardiac complications post-surgery. While German data on this topic are lacking, anesthesia and cardiology guidelines advocate for comprehensive evaluation and risk assessment of heart failure patients before non-cardiac surgeries with medium to high operative risk. However, there's a lack of systematic structures for assessing postoperative morbidity and mortality risks in an interdisciplinary and intersectoral context. Due to workload and resource constraints, comprehensive risk assessments are often delayed until shortly before surgery, leading to inadequate peri- and postoperative care. Evidence supporting improved outcomes through preoperative optimization of heart failure patients and risk-adapted precision medicine for non-cardiac surgeries is also lacking. Consequently, this study aims to evaluate a care model providing multimodal, interdisciplinary, and intersectoral optimization for high-risk patients aged 65 and above with elevated heart failure biomarkers (NT-proBNP\>450), regardless of prior heart failure diagnosis. The null hypothesis posits that standardized risk screening and multidimensional interdisciplinary care cannot reduce postoperative complications in these high-risk patients undergoing non-cardiac surgeries.

Group Intervention Description Intervention group Interdisciplinary decision-making for perioperative care A cardiology consultation is conducted, which includes a standardized evaluation. This includes, medical history and physical examination:ECG, Echocardiography, Determination of cardiac troponins and natriuretic peptides in the local central laboratory. The echocardiography aims to qualitatively and quantitatively describe the left and right ventricular systolic and diastolic dimensions and function, as well as the valvular apparatus, the collected findings are presented at the interdisciplinary and intersectoral preoperative medical (POM) conference. Bedside visits with the patient are also possible.During this conference, structured preoperative interdisciplinary and intersectoral case discussions take place, involving the attending outpatient physicians. The POM conference consists of Anesthesiology, Cardiologist, Treating surgeon and optimize preoperative therapy and plan further pre-, intra-, and postoperative as well as outpatient care.
