Hopkins study finds no 'cognitive decline' after use of heart-lung machine during bypass surgery

The use of a cardiopulmonary heart pump during coronary artery bypass grafting (CABG) surgery does not significantly damage such high-level mental tasks as thinking, reasoning and remembering, according to a study by Johns Hopkins researchers recently published in Neurology.

CABG surgery is effective for the relief of angina and reducing the risk of a heart attack but has been widely feared to cause "pump-related" damage to the cerebral cortex, according to Guy M. McKhann, M.D., a professor in the Department of Neurology at The Johns Hopkins University School of Medicine.

To gauge whether there was a clinical basis for this concern, McKhann led a non-randomized study comparing the cognitive abilities of on-pump CABG patients, off-pump CABG patients, nonsurgical patients with coronary artery disease and heart- healthy individuals. The results of the study showed that on-pump CABG patients had no significant differences in their higher-level mental functions than the other groups tested, according to McKhann.

"This outcome should be reassuring to both patients and surgeons engaged in on-pump CABG surgeries," McKhann said.

The study, conducted between September 1997 and September 2003, involved 380 individuals -- 140 on-pump CABG patients, 72 off-pump CABG patients, 99 nonsurgical patients with coronary artery disease and 69 heart-healthy patients.

Both the on-pump CABG patients and the nonsurgical patients with coronary artery disease were exclusively Hopkins-based, whereas the off-pump CABG patients came from Hopkins; Sinai Hospital, Baltimore, Md.; Washington Adventist Hospital, Takoma Park, Md.; University of Maryland Medical Center, Baltimore, Md., and Pinnacle Health System, Harrisburg, Pa.

Study participants were given a battery of standardized neuropsychological tests that were repeated three months and 12 months later.

Test scores were sorted and combined into eight areas: verbal memory, visual me
