This prospective observational study investigates the incidence of acute myocardial injury after radical prostatectomy for prostate cancer. Consecutive patients undergoing elective open or robot-assisted radical prostatectomy at the Martini-Klinik are included. High-sensitivity cardiac troponin I (hs-cTnI) is measured preoperatively and on postoperative days 1 and 2 to identify acute myocardial injury, defined according to the 4th Universal Definition of Myocardial Infarction. Secondary outcomes include the incidence of myocardial infarction, major adverse cardiac and cerebrovascular events, and mortality during the hospital stay and at 24 months. Baseline patient characteristics (age, BMI, cardiovascular risk factors including the Revised Cardiac Risk Index, comorbidities, and prior cardiac therapy) as well as surgical and tumor-specific parameters are recorded. Associations between acute myocardial injury and clinical variables are analyzed.

Primary endpoint: Acute myocardial injury, defined as a postoperative troponin concentration above the 99th percentile sex-specific upper reference limit with a) an increase of ≥ 50% from baseline if the baseline troponin I or T concentration was below the 99th percentile sex-specific upper reference limit or with b) an increase of ≥ 20% from baseline if the baseline troponin I or T concentration was above the 99th percentile sex-specific upper reference limit. percentile or with b) an increase of ≥ 20 % compared to the initial value if the initial troponin I or T concentration was above the sex-specific upper reference limit of the 99th percentile. Secondary endpoints: 1. recording the frequency of acute myocardial damage without or with clinical findings typical of ischaemia. 2. frequency of cardiovascular events during hospitalisation. Cardiovascular events are defined as follows: non-fatal cardiac arrest, heart failure, interventional coronary angiography, coronary artery bypass surgery, new-onset atrial fibrillation, stroke, pulmonary artery embolism, deep vein thrombosis of leg or arm. 3. correlation between the level of postoperative troponin increase and the occurrence of cardiovascular events during hospitalisation. 4. predictive value of the Revised Cardiac Risk Index for the occurrence of acute myocardial damage. 5. differences in the incidence of acute myocardial damage in open radical prostatectomies versus minimally invasive radical prostatectomies. Furthermore, the included patients are followed up for 24 months and questioned about cardiovascular events.
