In chronic case of myocardial infarction (OMI), alternation of a daily total energy consumption (DTEC) between in OMI and in the pre-infarction stage was investigated. The limiting factors of DTEC, including functional classification according to New York Heart Association (NYHA) subset, Forrester's hemodynamic subset (FS) in the stage of acute myocardial infarction (AMI), numbers of significant coronary arterial stenosis (NCAG), cardiac function at rest in OMI, for example; cardiac index (CI), pulmonary capillary wedge pressure (PCW), left ventricle end-diastolic pressure (EDP) and exercise tolerance in OMI, were considered. Subjects, consisting of 191 OMI cases, were classified into the younger group <59 years old (79 males and 10 females) and the older group >60 years old (102 males and 23 females). Daily physical activity was examined by questionnaries from these patients and DTEC was calculated based on daily physical activity. Results in the younger group and older group were investigated separately. Reduction of DTEC after myocardial infarction was recognized in all ages and both sexes. however, reduction of DTEC in the older group was less than in the younger group, especially in males. Concerning the limiting factors of the older group, exercise tolerance in OMI was related to reduction of DTEC. NYHA category, FS in the AMI stage, NCAG, CI, PCW and EDP had no significant relation to DTEC. In addition, the effects of social limiting factors, for instance retirement, and mental limiting factors were considered to be important.
