Minnesota Leisure Time Physical Activity Questionnaire as an additional Tool in Clinical Assessment of Patients undergoing Percutaneous Coronary Interventions

摘要

The aim was to analyze the usability of Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) in assessment of physical activity in patients before and 6 months after percutaneous coronary intervention (PCI). The study group consisted of 211 patients aged between 34-79 years (x = 59,5±7,89 yeras), with history of ischemic heart disease (IHD) with or without previous incidence of myocardial infarction (MI). The MLTPAQ was administered to all patients at the time of PCI and then 6 months later, as was the treadmill stress test (TST) and echocardiography (ECHO). Total energy expenditure calculated with the MLTPAQ remained at the same level and was of low intensity (4 MET, 2000kcal/week) 6 months after the PCI. There was an increased physical capacity noted 6 months after initial PCI: increased metabolic cost (MET); maximal oxygen uptake (VO2max); maximal heart rate (HRmax) obtained during the TST and decreased resting heart rate (HRrest). ECHO examination showed improved LVEF%. Despite increased physical capacity and improved heart hemodynamics, resulting most likely from PCI procedure, the patients showed a similar level of leisure time physical activity 6 months after the PCI.
