Perioperative Myocardial Injury Clinical Trial
— PMI-VITALOfficial title:
Continuous Monitoring of Vital Signs for Improved Phenotyping of Perioperative Myocardial Infarction/Injury After Noncardiac Surgery in High Risk Patients: PMI-VITAL
The goal of this observational prospective cohort study is to learn about the pathophysiology of perioperative myocardial infarction/injury in high-risk patients undergoing major non-cardiac surgery. Participants will: - Wear wearable device (Basler Band) for up to seven days after the operation or until hospital discharge - Provide three blood samples. A venous specimen of blood (25 mL) will be collected preoperatively and on postoperative days 1 and 2. - Be contacted to answer a questionnaire one year after the surgery.

Primary | Perioperative myocardial infarction/injury (PMI) | PMI is defined as an absolute increase in high-sensitivity cardiac troponin (hs-cTn) of the 99th percentile of healthy individuals for the respective assay above baseline cTn-value or between two postoperative values if the preoperative value was missing.
PMI will be further classified as type I myocardial infarction, type II myocardial infarction, or myocardial injury due to non-cardiac causes. Two independent cardiologists or anaesthesiologists will adjudicate all PMI cases. |
3 days after surgery | |
Primary | Major adverse cardiac and cerebral events (MACCE) | MACCE is defined as a composite of all-cause death, acute myocardial infarction, acute heart failure (requiring admission to a hospital or intra-hospital transfer to the internal medicine or intensive care unit), clinically relevant arrhythmias (cardiac arrest, sustained ventricular tachycardia, atrioventricular (AV)-block III, high rate atrial fibrillation/flutter requiring treatment, bradycardia requiring pacemaker, or rhythmogenic syncope) and stroke/transient ischaemic attack within one year. | 1 year | |
Primary | Postoperative atrial fibrillation (POAF) | POAF is defined as new-onset atrial fibrillation (AF) in the immediate postoperative period of duration/burden at least 30 minutes detected using continuous monitoring of vital signs using the wearable device (Basler Band), but not recorded and documented using the current clinical monitoring standards. | During surgery and up to 7 days after surgery or until hospital discharge. | |
Primary | Documentation and quantification of the frequency and duration of tachyarrhythmia, bradycardia, hypotension, hypertension, and/or hypoxaemia. | Frequency and duration of tachyarrhythmia, bradycardia, hypotension, hypertension, and/or hypoxaemia detected using continuous monitoring of vital signs using the "Basler Band" throughout the whole perioperative period, and use this information to characterise PMI.
Major abnormalities will be defined as: hypotension (systolic blood pressure <85 mmHg or more than 40 mmHg lower than at the initiation of analgosedation for >10 minutes), hypertension (systolic blood pressure >190 mmHg >20 minutes), tachyarrhythmia (ventricular rate >120 for >20 minutes), bradycardia (asystole >10 s or heart rate <40/min for >30 minutes), and/or hypoxaemia (pulse oximetry <85% for >20 minutes). |
During surgery and up to 7 days after surgery or until discharge. | |
Primary | Comparison of the incidence and prognostic impact of PMI detected by using different troponin assays | Comparison of the incidence and prognostic impact of PMI detected by using different high-sensitivity cardiac troponin I (hs-cTnI) assays in parallel to the clinical PMI-screening using high-sensitivity cardiac troponin T (hs-cTnT) assays. | 3 days after surgery | |
Primary | Using biomarkers as tools for prediction of major cardiac complications in patients undergoing non-cardiac surgery | Evaluation of the incremental value of additional cardiovascular biomarkers and continuous vital sign monitoring in the prediction of PMI and other cardiac complications, as well as the prediction of death, and the understanding of the pathophysiology of PMI. | 3 days after surgery | |
Secondary | Number of patients with PMI with ischemic symptoms and signs detected in a screening program in high-risk patients undergoing major non-cardiac surgery | Patients with PMI are evaluated for: presence of chest pain, atypical symptoms, palpitations, dyspnea, edema, or nausea; ST-changes, Q-waves, T-wave abnormalities, new bundle branch block. | 3 days after surgery |
