Structured case management may improve recovery after CABG in older adults with type 2 diabetes
Last updated June 2, 2026
Key finding
In a 6-month randomized trial of 168 elderly patients with type 2 diabetes after off-pump CABG, structured multidisciplinary case management improved cardiac function, HbA1c, walking distance, lipids, and quality-of-life outcomes versus routine care.
This trial tested a structured case management program in older adults with type 2 diabetes recovering from off-pump CABG. Compared with routine care alone, the program improved heart function, HbA1c, walking distance, lipid measures, and patient-reported recovery over 6 months.

Main Effects
Structured case management ↑ left ventricular ejection fraction at 6 months
Structured case management ↓ HbA1c, triglycerides, total cholesterol, and LDL cholesterol
Structured case management ↑ walking distance, quality of life, and daily living scores
Evidence Suggest
- The primary endpoint, LVEF change, improved by 6.2 percentage points versus routine care
- HbA1c improved by 1.3 percentage points and multiple lipid outcomes also favored the intervention
- Functional and patient-reported recovery outcomes improved while serious adverse events were similar between groups
Who this applies to
Older adults aged 65 years or above
Keep in Mind
The intervention was multi-component, so the study cannot isolate which component mattered most
Between the Lines
- Single-center study in a tertiary hospital in Tianjin
- Participants and care teams were not blinded to the intervention
- The population was selected as relatively low-risk for rehabilitation, which may limit generalizability
- Follow-up lasted 6 months, so longer-term cardiovascular outcomes remain uncertain
