[Myocardial infarct after gastroscopy. Case report and pathogenetic considerations]
Schweizerische Medizinische Wochenschrift
|July 10, 1976
Summary
Patients with coronary heart disease face significant risks during gastroscopy. Endoscopic procedures can trigger myocardial infarction and ischemia due to factors like tachycardia and coronary artery proximity.
Area of Science:
- Cardiology
- Gastroenterology
- Medical Procedures
Context:
- Coronary heart disease (CHD) patients undergoing gastrointestinal endoscopy.
- Gastroscopy as a common diagnostic procedure.
- Potential cardiovascular complications of endoscopic interventions.
Purpose:
- To report cases of myocardial infarction and ischemia post-gastroscopy in CHD patients.
- To highlight the elevated risks associated with endoscopy in this population.
- To explore the underlying pathogenetic mechanisms.
Summary:
- Three cases of myocardial infarction and severe myocardial ischemia following gastroscopy are presented.
- These events occurred in patients with pre-existing coronary heart disease.
- Pathogenetic factors implicated include catecholamine-mediated tachycardia and proximity of the esophagus to the right coronary artery, potentially inducing coronary spasms.
Impact:
- Underscores the critical need for risk assessment before gastroscopy in CHD patients.
- Suggests enhanced monitoring and preventative strategies during endoscopy for at-risk individuals.
- Informs clinical practice regarding the cardiovascular safety of gastroscopy.
