Why the study?

Risk factors for stress-induced hyperglycemia in patients without diabetes after cardiac surgery required systematic evaluation.

Do specific clinical and procedural risk factors increase the risk of postoperative stress hyperglycemia in patients without diabetes following cardiac surgery?

Comparison

Presence vs absence of clinical and procedural risk factors

Design

Systematic review and meta-analysis of 8 case-control and 3 cohort studies

Key result

Age >65 years (OR 3.47) and cardiopulmonary bypass time >2 hours (OR 20.26) were identified as major risk factors for postoperative stress hyperglycemia in patients without diabetes following cardiac surgery.

Overview

May identify high-risk non-diabetic patients after cardiac surgery; leaves open prospective validation before guiding practice.

Study Design

Type

Systematic Review (n=11,645)

Structured PICO

Do specific clinical and procedural risk factors increase the risk of postoperative stress hyperglycemia in patients without diabetes following cardiac surgery?

P
Population
11,645 patients without diabetes who underwent cardiac surgery across 11 studies, evaluated for risk factors associated with postoperative stress hyperglycemia.
E
Exposure
Presence of clinical and procedural risk factors (including age >65 years, female gender, combined heart valve and coronary artery bypass surgery, ejection fraction <40%, history of heart surgery, myocardial infarction, hyperlipidemia, hypertension, anticoagulant medication, cardiopulmonary bypass time >2 hours, and history of cardiopulmonary bypass).
C
Comparator
Absence of the respective clinical and procedural risk factors.
O
Outcome
Postoperative stress hyperglycemia (defined as fasting blood glucose >7.0 mmol/L or random blood glucose >11.1 mmol/L on two or more occasions).surrogate

Main Result

Odds Ratio: 3.47 (95% CI 2.61–4.32)

p-value: p=<0.00001

In non-diabetic patients undergoing cardiac surgery, prolonged cardiopulmonary bypass time, advanced age, and combined surgical procedures are major risk factors for developing postoperative stress hyperglycemia.

Limitations

  • Variability in the types of studies included
  • Bias in the selection of risk factors across different studies
  • Heterogeneity among included studies due to varying clinical characteristics and disease severity
  • Different study designs introducing inherent biases and limitations
  • Potential publication bias from low-quality studies

Cite This Study

Zhang et al. (2025) conducted a systematic review in Postoperative stress hyperglycemia (n=11,645). Age >65 years vs. Age ≤65 years was evaluated on Postoperative stress hyperglycemia (OR 3.47, 95% CI 2.61-4.32, p=<0.00001). Age >65 years (OR 3.47) and cardiopulmonary bypass time >2 hours (OR 20.26) were identified as major risk factors for postoperative stress hyperglycemia in patients without diabetes following cardiac surgery.
