Abstract [en]

Patients with myocardial infarction with nonobstructive coronary arteries (MINOCA), including Takotsubo syndrome (TS), are considered to have a better survival compared with those with coronary heart disease (CHD). Studies of patients with MINOCA measuring physical and mental function including matched control groups are lacking. The aim of this study was to determine the physical capacity and quality of life in patients with MINOCA. One-hundred patients with MINOCA along with TS (25%) were investigated from 2007 to 2011. A bicycle exercise stress test was performed 6 weeks after hospitalization and QoL was investigated by the Short Form Survey 36 at 3 months' follow-up. Both a healthy and a CHD group that were age and gender matched were used as controls. The MINOCA group had a lower physical capacity (139 ± 42 W) compared with the healthy control group (167 ± 53 W, p <0.001) but better than the CHD control group (124 ± 39 W, p = 0.023). Patients with MINOCA had lower physical and mental component summary scores compared with the healthy controls (p <0.001) and lower mental component summary (p = 0.012), mental health (p = 0.016), and vitality (p = 0.008) scores compared with the CHD controls. In conclusion, the findings of this first study on exercise capacity and QoL in patients with MINOCA showed both physical and mental distress from 6 weeks to 3 months after the acute event similar to CHD controls and in some perspectives even lower scores especially in the mental component of QoL.
