Learning Objective 1: The learner will be able to understand the effect of lifestyle modification by the self-monitoring for 6 month in patient with coronary heart disease.

Learning Objective 2: The learner will be able to obtain a suggestion for supporting patients with coronary heart disease using a self-monitoring method.

Purpose: The aim of this study is to suggest whether the frequency of self-monitoring for 6 months is related to the physical condition, nutrient intake, and physical activity in male patients with ischemic heart disease.

Methods: Participants included 41 male outpatients with ischemic heart disease who were recruited at cardiovascular clinics. For 6 months, the patients recorded their physical condition, eating habits, exercise, and any incidents in a “ health diary”. The frequency of these diary entries and the patients’ physical condition (blood pressure, body mass index, and serum lipid), nutrient intake, and physical activities were assessed at baseline and 1, 3and 6 months after initiating self-monitoring.

Results: The average number of days for which the patients wrote in their diaries for 6 months  was 136.0 ± 52.1 per person (74.9 ± 26.2%). The frequency of diary entries for 6 months had a significantly negative correlation (p < 0.05) with BMI (r = −0.38), but did not show any significant correlation with blood pressure, serum cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, daily caloric and cholesterol intake, and activity levels. A comparison between the patients who made diary entries 50% or more of the time and those who made diary entries less than 50% of the time showed that the total cholesterol in the former group was 180.9 ± 28.7 mg/dl before self-monitoring began and had significantly dropped to 173.4 ± 28.4 mg/dl 6 months later, while the latter group showed no such significant difference (p < 0.05). There were no significant differences between the two groups in daily caloric intake, daily salt intake, and activity levels.

Discussion: It is to suggest that the frequency of self-monitoring for 6 months was significantly correlated with changes in BMI and serum lipids, but not with physical activity in patients with ischemic heart disease.
