What is the clinical evidence from this study?

Study design: Observational. Population: Coronary artery disease undergoing vascular surgical procedure (n=51). Intervention: Disabling angina pectoris (Class III and IV) vs. Class II or less or no angina. Primary outcome: Occurrence of myocardial ischemia during the perioperative period (p=<0.001).

Clinical Predictors of Intraoperative Myocardial Ischemia in Patients with Coronary Artery Disease Undergoing Non‐Cardiac Surgery

Q: What are the key findings of this study?

Disabling angina pectoris (Class III and IV) strongly predicted perioperative myocardial ischemia compared to mild or no angina (87.5% vs 17.1%, P<0.001) in patients undergoing vascular surgery.

Q: What question did this study set out to answer?

The aim is to identify clinical predictors of myocardial ischemia in patients with coronary artery disease undergoing non-cardiac surgery.

Overview

Perioperative ischemia common in CAD vascular patients; leaves open whether routine Holter monitoring improves risk stratification or outcomes.

Key Points

The aim is to identify clinical predictors of myocardial ischemia in patients with coronary artery disease undergoing non-cardiac surgery.
Continuous electrocardiogram monitoring by the Holter method was performed in 51 patients.
Preoperative clinical parameters were evaluated to predict the occurrence of myocardial ischemia.
Episodes of myocardial ischemia were recorded during the perioperative period.
20 out of 51 patients experienced 36 episodes of myocardial ischemia, starting in 11 cases during induction.
14 out of 16 patients with Class III and IV disabling angina developed myocardial ischemia (P<0.001).
All patients without or with only mild angina who had ischemic episodes showed ST-T abnormalities on preoperative electrocardiograms.

Type

Observational (n=51)

Structured PICO

Can preoperative clinical parameters predict intraoperative myocardial ischemia in patients with CAD undergoing vascular surgery?

Population

51 patients with coronary artery disease undergoing a vascular surgical procedure monitored for perioperative myocardial ischemia.

Exposure

Preoperative clinical evaluation and continuous Holter ECG monitoring

Outcome

Main Result

Absolute Event Rate: 87.5% vs 17.1%

p-value: p=<0.001

The degree of preoperative angina disability strongly predicts the risk of intraoperative myocardial ischemia in CAD patients undergoing vascular surgery.
