Cardiovascular responses to upper gastrointestinal endoscopy
The American Journal of Gastroenterology
|June 1, 1978
Summary
Upper gastrointestinal endoscopy is safe for patients with cardiovascular disease. However, monitoring heart rate and blood pressure during the procedure can help reduce cardiac stress.
Area of Science:
- Cardiology
- Gastroenterology
- Medical Monitoring
Background:
- Upper gastrointestinal endoscopy is a common procedure.
- Patients with cardiovascular disease may be at higher risk during endoscopic procedures.
Purpose of the Study:
- To assess the cardiovascular safety of upper gastrointestinal endoscopy.
- To evaluate the impact of sedation and the procedure on cardiovascular parameters.
Main Methods:
- Continuous Holter monitoring and serial blood pressure recordings were performed on 51 patients undergoing endoscopy.
- Patients included those with and without pre-existing cardiovascular disease.
Main Results:
- Intravenous diazepam sedation caused a significant decrease in blood pressure and heart rate.
- During endoscopy, heart rate and rate-pressure product increased significantly.
- Electrocardiographic changes, including arrhythmias and ST depression, occurred in 9 patients, with no significant difference between those with and without cardiovascular disease.
Conclusions:
- Upper gastrointestinal endoscopy can be safely performed in patients with cardiovascular disease.
- Minimizing cardiac stress during endoscopy can further enhance patient safety.
