    A study on the short-term cognitive outcome of percutaneous transluminal coronary angioplasty with intra-coronary stenting
    (2006) Macfarlane, Robert; Ameen, Ozayr
    This study explores the short term cognitive outcome of percutaneous transluminalcoronary angioplasty with intra-coronary stenting. Participants were assessed cognitively using specific neuropsychological tests used to measure performance in the seven cognitive domains. Forty people took part in the study, with twenty of them making up the stented group, and twenty of them making up the control group. The stented group were assessed a few days before, and then a few weeks after their procedures. The control group were simply assessed whenever they agreed to participate, and then again a few weeks later. There were ten males and ten females in each group. The participants were all between the ages of 34 and 75, and the sample had an average age of 57. The researchers were given access to patients at Groote Schuur Hospital and Gatesville Medical Centre. Analysis of variance was used in order to assess differences between the groups with respect to changes in cognitive performance in all seven cognitive domains. Results indicated that there were not significant differences between the groups, with respect to changes in cognitive performance between the first and second interviews.
