[Correlation between prior coronary revascularization and perioperative cardiac events in patients for noncardiac
Insights
The timing of noncardiac surgery after coronary revascularization impacts cardiac events. Performing surgery soon after percutaneous transluminal coronary angioplasty or long after bypass grafting increases cardiac complication risks.
Area of Science:
- Cardiology
- Cardiac Surgery
- Vascular Surgery
Context:
- Patients with prior coronary revascularization undergoing noncardiac surgery face perioperative cardiac risks.
- Understanding these risks is crucial for optimizing patient management and outcomes.
Purpose:
- To evaluate the influence of the interval between prior coronary revascularization and subsequent noncardiac surgery on perioperative cardiac events.
- To identify risk factors associated with adverse cardiac outcomes in this patient population.
Summary:
- A retrospective study of 162 patients found 6.2% experienced postoperative cardiac complications.
- Complications were higher in patients with unstable angina, recent myocardial infarction, cerebrovascular disease, peripheral vascular disease, renal dysfunction, and higher preoperative risk scores.
- Increased cardiac complications were observed when noncardiac surgery was performed within 1 week of percutaneous transluminal coronary angioplasty (PTCA) or more than 5 years after coronary artery bypass grafting (CABG) or PTCA.
Impact:
- The study highlights the importance of considering the time elapsed since coronary revascularization and patient-specific atherosclerotic risk factors when assessing perioperative cardiac risk.
- Findings can inform clinical decision-making regarding the optimal timing for noncardiac surgery in patients with a history of coronary revascularization.
Abstract:
We evaluated the influence of interval between prior coronary revascularization and subsequent noncardiac surgery on perioperative cardiac events. We retrospectively identified 162 consecutive patients with previous revascularization procedures who had undergone noncardiac surgery. Postoperative cardiac complications occurred in 10 (6.2%) patients, cardiac death in 1 patient, and significant arrhythmia in 3 patients. These patients had higher rates of unstable angina, myocardial infarction within 3 months, cerebrovascular disease, peripheral vascular disease, renal dysfunction (Cr > or = 1.9 mg.dl-1) and higher preoperative risk scores as described by the Cleveland Clinic (P < 0.05). Also, the incidence of cardiac complications increased when noncardiac surgery was performed within 1 week of previous percutaneous transluminal coronary angioplasty (PTCA) and in more than 5 years after coronary artery bypass grafting or PTCA (P < 0.05). Although PTCA is widely accepted, especially in Japan, early lesion progression was observed during the first several days and atherosclerotic progression was apparent in more than 5 years after the procedure. Therefore, the time between coronary revascularization and noncardiac surgery, as well as atherosclerotic risk factors, is important in evaluating patients with history of previous revascularization procedures.
