INSIGHT: Perioperative Inflammatory Response Assessment in High-risk Patients Undergoing Noncardiac Surgery
Study Details
Study Description
Brief Summary
Postoperative cardiovascular complications are common after noncardiac surgery. The association between perioperative inflammation and the occurrence of cardiovascular complications after surgery is still unknown. Therefore, we will evaluate as our primary aim the association between patients with increased postoperative inflammation, assessed with C-reactive protein measurements, and the occurrence of major cardiovascular complications after noncardiac surgery. We will further evaluate the influence of perioperative inflammation on the occurrence of postoperative acute kidney injury. We will also evaluate the association between inflammation and the influence on Days-At-Home within 30 days. Furthermore, we will evaluate the association between increased inflammatory biomarkers and postoperative N-terminal pro brain natriuretic peptide (NT-proBNP) concentration.

Outcome Measures
Primary Outcome Measures
- Composite of cardiovascular complications [within 30 days after surgery and one year after surgery]
The primary aim of the study is to investigate the influence of the maximum C-reactive protein value (over the first 3 days after surgery) on the incidence of major cardiovascular complications within 30 days after surgery. The composite binary endpoint is defined as myocardial infarction, myocardial injury after noncardiac surgery, new onset of atrial fibrillation, stroke or death.
Secondary Outcome Measures
- C-reactive protein [within 30 days after surgery]
Secondary goals of the study are to investigate the influence of the C-reactive protein on day 5 on the incidence of cardiovascular complications within 30 days after surgery (combined binary endpoint).
- Acute Kidney Injury - C-reactive proteint [within 5 days after surgery]
We will evaluate the influence C-reactive protein on the occurrence of postoperative acute kidney injury.
- Acute Kidney Injury - Interleukin 6 [within 5 days after surgery]
We will evaluate the influence of Interleukin 6 on the occurrence of postoperative acute kidney injury.
- Acute Kidney Injury - Procalcitonin [within 5 days after surgery]
We will evaluate the influence of Procalcitonin on the occurrence of postoperative acute kidney injury.
- Acute Kidney Injury - Copeptin [within 5 days after surgery]
We will evaluate the influence of Copeptin on the occurrence of postoperative acute kidney injury.
- Days at home within 30 days (DAH 30) [within 30 days after surgery]
We will evaluate the correlation between perioperative inflammation (C-reactive protein, Interleukin 6, Procalcitonin, Copeptin) and the number of days patient spend at home after surgery within 30 days (DAH30). Outcomes measure: Hospital discharge data will be used to calculate hospital length of stay. DAH30 will be calculated using mortality and hospitalization data from the date of the index surgery (day 0). For example, if a patient will die on day 2 after surgery, they were assigned 0 DAH30. If a patient will be discharged from hospital at day 6 after surgery but will be readmitted for 4 days before the second hospital discharge, we will assign 20 DAH30. If a patient will die within 30 days after surgery, irrespective of whether they will spend time at home, DAH30 will be scored as 0.
- NT-proBNP [within 5 days after surgery]
We will evaluate the correlation of each of the following inflammatory parameters including C-reactive protein, Interleukin 6, Procalcitonin, Copeptin on postoperative NT-proBNP concentration. NT-proBNP will be measured before surgery, and on the first, second and third postoperative day.
- Interleukin 6 [within 30 days after surgery]
We investigate the influence of the Interleukin 6 ,measured within the first five days after surgery, on the incidence of cardiovascular complications within 30 days after surgery (combined binary endpoint).
- Copeptin [within 30 days after surgery]
We investigate the influence of the copeptin ,measured within the first five days after surgery, on the incidence of cardiovascular complications within 30 days after surgery (combined binary endpoint).
- Procalcitonin [within 30 days after surgery]
We investigate the influence of the procalcitonin ,measured within the first five days after surgery, on the incidence of cardiovascular complications within 30 days after surgery (combined binary endpoint).
Other Outcome Measures
- Atrial fibrillation (AF) evaluation [within 5 days after surgery]
To evaluate the incidence of asymptomatic atrial fibrillation (AF) and symptomatic AF. Asymptomatic AF will be defined as irregular pulse without any clinical symptoms. Symptomatic AF will be defined as irregular pulse with one of the symptoms including racing heart, fluttering or palpitations; fatigue, shortness of breath; and lightheadedness.
- SARS-Cov-2 - Inflammation [within first 5 days after surgery]
We will evaluate the effect of having a perioperative or previous infection with Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) on postoperative inflammatory parameters including C-reactive protein, Copeptin, Interleukin 6 and Procalcitonin.
- SARS-Cov-2 - Cardiovascular Complications [One year after surgery]
We will evaluate the effect of having a perioperative or previous infection with SARS-CoV-2 on the incidence of our composite outcome including myocardial myocardial infarction, myocardial njury after noncardiac surgery, new onset of atrial fibrillation, stroke or death. We will evaluate the outcome one year after surgery via a telephone interview.
- SARS-Cov-2 One Year Follow-Up [One year after surgery]
We will evaluate the effect of a perioprative or previous SARS-Cov-2 infection on the neurocognitive function one year after surgery. Therefore, we will perform the telphone Montreal Cognitive Assessment (MoCA) before surgery and one year after surgery.
