Insights
Neuropsychological outcomes are similar after coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA). However, executive functioning is impaired post-revascularization, and psychiatric issues are common after PTCA but improve.
Area of Science:
- Cardiology
- Neuropsychology
- Psychiatry
Background:
- Coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA) yield similar medical outcomes.
- Limited research exists comparing neuropsychological outcomes between CABG and PTCA.
Purpose of the Study:
- To compare detailed neurocognitive and psychosocial functioning between patients undergoing CABG and PTCA.
- To assess executive functioning, processing speed, attention, learning, memory, psychopathology, and psychosocial health.
Main Methods:
- Retrospective analysis of 32 patients (16 CABG, 16 PTCA) 9-15 months post-procedure.
- Neurocognitive and psychosocial assessments including General Health Questionnaire (GHQ) and SF-36.
- Prospective evaluation of 55 patients undergoing PTCA using GHQ and SF-36 pre- and post-procedure.
Main Results:
- No significant differences in neuropsychological or psychosocial endpoints between CABG and PTCA groups.
- Both groups exhibited poorer executive functioning compared to healthy controls.
- PTCA patients showed higher rates of psychiatric abnormality (GHQ > 4) than CABG patients, but improved post-intervention.
Conclusions:
- Neuropsychological status is comparable following CABG and PTCA, despite common executive function impairments.
- Psychiatric pathology is prevalent in PTCA patients but demonstrates improvement after the procedure.
Background:
Medical outcomes following coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA) are similar, but few studies have compared neuropsychological outcomes after these procedures.
Methods:
A retrospective study compared detailed neurocognitive and psychosocial functioning in 32 patients (CABG, n = 16; PTCA, n = 16) aged 61 +/- 6 years, 9-15 months after coronary revascularisation. Subjects were tested for executive functioning, speed of processing/attention and learning/memory, significant psychopathology (General Health Questionnaire, GHQ) and psychosocial functioning (Short Form (SF)-36 health survey). In the prospective study, 55 patients completed GHQ and SF-36 surveys, the day prior to and 6 months following PTCA.
Results:
There were no significant differences between the CABG and PTCA groups for neuropsychological or psychosocial end-points (P > 0.20). Executive functioning in both groups, however, was worse than for healthy population controls (P < 0.01). The PTCA patients were significantly more likely than CABG patients to have psychiatric abnormality (GHQ Score >4; P < 0.01). After PTCA, however, there was a significant improvement in the GHQ and SF-36 scores (P < 0.05).
Conclusions:
Although executive function is often impaired after coronary revascularisation, neuropsychological status appears equivalent after CABG or PTCA. Psychiatric pathology is common in patients undergoing PTCA, but improves after this intervention.
