Clinical Scorecard: Outcomes of Cardiac Surgery Among Patients with a History of Bariatric Procedures
At a Glance
Category
Detail
Condition
Obesity and cardiovascular disease in patients undergoing cardiac surgery
Key Mechanisms
Metabolic and bariatric surgery (MBS) leads to durable weight loss and multisystem benefits reducing mortality and complications
Target Population
Adults eligible for bariatric surgery undergoing cardiovascular surgery
Care Setting
Inpatient hospital setting during cardiovascular surgery
Key Highlights
Patients with a history of MBS had lower in-hospital mortality (0.9% vs. 1.7%) after cardiac surgery compared to MBS-eligible patients without MBS.
MBS patients experienced fewer respiratory complications including pneumonia and respiratory failure, and fewer infectious complications.
In obesity class 3 patients, MBS was associated with significantly fewer pneumonia and infections compared to non-MBS counterparts.
Guideline-Based Recommendations
Diagnosis
Identify patients eligible for MBS based on BMI >35 or BMI 30-35 with metabolic comorbidities per American Society for Metabolic and Bariatric Surgery criteria.
Management
Consider MBS as a treatment option for eligible obese patients to improve cardiovascular surgery outcomes.
Monitor and manage comorbidities such as autoimmune conditions, anemia, and diabetes in patients undergoing MBS.
Monitoring & Follow-up
Monitor for nutritional deficiencies post-MBS, including anemia.
Assess for respiratory and infectious complications post-cardiac surgery, especially in obese patients.
Risks
Recognize that MBS patients may have higher prevalence of autoimmune conditions and deficiency anemia.
Be aware of potential nutritional deficiencies as common morbidities post-MBS.
Patient & Prescribing Data
Adults undergoing cardiovascular surgery with obesity and eligibility for bariatric surgery
MBS is underutilized (1.1% of eligible patients) despite evidence of reduced mortality and complications post-cardiac surgery.
Clinical Best Practices
Use propensity score matching to adjust for confounders when comparing outcomes between MBS and non-MBS patients.
Stratify patients by obesity class to identify differential benefits of MBS on surgical outcomes.
Evaluate and optimize comorbid conditions prior to cardiac surgery in patients with obesity.
