The aim of the paper is to analyze the association between heart function among obese patients and Type D personality to predict the potential risk for coronary heart disease (CHD). Overall, 30 obese patients were evaluated for the DS14 score. Body mass with body mass index (BMI), systolic and diastolic blood pressure, heart rate (HR), and heart rate variability (HRV) were measured before and after a 3-month period. Half of the subjects had been instructed to exercise 4-times weakly (walking 5 km/h) for an hour, the other half did not exercise. Additionally, STAX-1, SWLS, and QOLLTI-P questionnaires had been used. All participants had a normal CRP and sedimentation rate at the enrolment and after 3-month follow up. None of the psychological tests (STAX-1, SWLS and QLLTI-P) showed statistical difference in results between June and October. Participants who exercised showed lower HR compared to participants who did not exercise. Obese patients with high DS14 score showed reduced HRV as an additional risk factor for the future cardiovascular and other stress-related diseases. Type D personality was associated with an increased risk of CHD proved by the HRV measures when the individual was not exercising. Thus, individual personality in fact correlates to autonomic regulation of the heart.
