About this study
Official title: Evaluation of a Model for Post-anesthesia Troponin Increase and Heart Injury Estimation
This study evaluates the preoperative cardiovascular risk, the intraoperative hemodynamic characteristics and the surgical photo-plethysmographic index of patients undergoing general anesthesia for non-cardiac vascular surgery to develop a multiple variable model assessing the risk for postoperative myocardial ischemic events.
Read the detailed description
Perioperative cardiac troponin leak is common and is strongly associated with mortality even in absence of classic myocardial infarction signs. In the VISION study 11.6% of patients undergoing non-cardiac surgery were troponin positive and 1.9% (95%CI 1.7-2.1%) of those patients died within 30 days of surgery. In selected populations of patients undergoing vascular surgery, a postoperative cTn leak, without clinical features of myocardial ischemia, is associated with an increased risk of 30-day mortality (odds ratio 5.03, 95% CI 2.88-8.79). Myocardial oxygen supply-demand imbalance and plaque rupture/thrombosis are the main mechanism involved in the pathogenesis of postoperative myocardial ischemic events. Frequently cardiac troponin leaks occur in absence of classical signs and symptoms of myocardial infarction. More than 80% of patients with postoperative cardiac troponin leak are clinically asymptomatic for myocardial ischemia, and ischemic ECG changes are often absent.
The identification of patients who will experience a postoperative myocardial ischemia will continue to be a challenge for anaesthesiologists.The current tool used for risk stratification using the AHA/ACC algorithm is Lee's Revised Cardiac Risk Index. Unfortunately, this tool can only reliably exclude low-risk patients and cannot identify patients which are likely to have perioperative cardiovascular complications.
The surgical plethysmographic index (SPI, GE Healthcare, Finland) during general anaesthesia has been correlated with the stressors of surgery (e.g. intubation, incision, …), and with stress hormone production. It has been demonstrated that SPI and other pulse photo-plethysmographic indices reflect sympathetic-mediated vasoconstriction, thus monitoring the SPI during general anesthesia could lead to a reduced sympathetic response to surgical stimuli. Unfortunately there is not a desirable level of SPI, and it is unknown if difference in SPI values during the surgery might affect the postoperative outcome.
Intraoperative hemodynamic parameters and SPI will be recorded in conjunction with preoperative cardiovascular risk scores and will be used to develop a multiple variable model for postoperative risk of myocardial ischemic events.
In this study Electrocardiogram, invasive arterial pressure, photoplethysmography,and electroencephalographic entropy will be collected continuously from 10 min before induction of general anesthesia until 20 min after awakening from anesthesia. Gupta's score and Revised Cardiac Risk Index will be recorded the day before surgery.
Blood samples for high sensitive cardiac troponin T (hs-TnT) assay will be collected on day of surgery (baseline) and on postoperative day 1, 2 and 3. According to this methodology, in this study postoperative myocardial ischemic events will be defined as:
- Myocardial Infarction according to the third universal definition (Thygesen K. et al. Third universal definition of myocardial infarction. Circulation 2012;126:2020-35 )
- Myocardial Injury defined a hs-TnT plasmatic concentration of (i) 20-65 ng/L with an increase >5ng/L between baseline to days 1-3, or (ii) >65 ng/L, or (iii) a rise >50% between baseline and days 1-3 in case of renal insufficiency, all of them in absence of non-ischemic causes of troponin increase (sepsis, pulmonary embolism, electrical cardioversion and acute respiratory failure).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study evaluates the preoperative cardiovascular risk, the intraoperative hemodynamic characteristics and the surgical photo-plethysmographic index of patients undergoing general anesthesia for non-cardiac vascular surgery to develop a multiple variable model assessing the risk for postoperative myocardial ischemic events.
Detailed description
Perioperative cardiac troponin leak is common and is strongly associated with mortality even in absence of classic myocardial infarction signs. In the VISION study 11.6% of patients undergoing non-cardiac surgery were troponin positive and 1.9% (95%CI 1.7-2.1%) of those patients died within 30 days of surgery. In selected populations of patients undergoing vascular surgery, a postoperative cTn leak, without clinical features of myocardial ischemia, is associated with an increased risk of 30-day mortality (odds ratio 5.03, 95% CI 2.88-8.79). Myocardial oxygen supply-demand imbalance and plaque rupture/thrombosis are the main mechanism involved in the pathogenesis of postoperative myocardial ischemic events. Frequently cardiac troponin leaks occur in absence of classical signs and symptoms of myocardial infarction. More than 80% of patients with postoperative cardiac troponin leak are clinically asymptomatic for myocardial ischemia, and ischemic ECG changes are often absent.

Unfortunately, this tool can only reliably exclude low-risk patients and cannot identify patients which are likely to have perioperative cardiovascular complications.

Questions about this trial
What is this clinical trial studying?
An observational study of Postoperative Myocardial Ischemia, run by ASST Fatebenefratelli Sacco at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prediction of Postoperative Myocardial Ischemia (time frame: 72 hours after the surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03375476, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2020.
