Data on the MacNew and its development have been reported in a total of 76 publications including the 17 validation studies. Of the 59 non-validation reports, 39 [66%] are interventional studies with a total of 8,960 patients; of these 39 studies, 18 [46%] are randomized controlled trials. Of the 39 interventional studies, 21 [54%] included patients with coronary
heart disease, 10 [26%] where the diagnosis was specified as MI, four [10%] either angina or heart failure and four [10%] either ICD or pacemaker. Of the interventional studies, cardiac rehabilitation is the intervention of interest in 23 studies [59%] with an invasive procedure the focus of 11 studies [28%]. The other 20 publications reported on MacNew psychometrics, predictors or determinants of MacNew HRQL and cross-sectional comparisons with other instruments. These observations support previous reports of the potential of the MacNew as a core HRQL questionnaire in patients with IHD, specifically in patients with angina, heart failure or MI.
