Population Screening for Coronary Artery Calcification Does Not Increase Mental Distress and the Use of Psychoactive Medication

Abstract

Detection of coronary artery calcification (CAC) has been proposed for population screening. It remains unknown whether such a strategy would result in unnecessary concern among participants. Therefore, we set out to assess whether CAC screening affects the psychological well-being of screening participants. A random sample of 1825 middle-aged subjects (men and women, 50 or 60 y old) were invited for health screening. The European HeartScore was calculated, and a CAC score was measured using a cardiac computed tomography scanner. Therapeutic interventions as a result of the observations were at the discretion of the individual general practitioner. Before screening and at 6-month follow-up a depression test (Major Depression Inventory) was conducted, and the use of psychoactive medication was recorded. A total of 1257 (69%) subjects agreed to participate. Because of known cardiovascular disease or diabetes mellitus, 88 persons were excluded. Of the remaining 1169, 47% were men, and one half were 50 years old. At 6-month follow-up, significant reductions were observed in the Major Depression Inventory score from 5.3 to 3.9 (P<0.0001) and in the prescription rates of psychoactive medication from 7.1% (83 of 1169) to 6.2% (72 of 1169) (P=0.003). The results were independent of sex, age, HeartScore, CAC Score, and changes in other medication. A population screening program including CAC score appears to have no detrimental impact on mental distress and does not increase the use of psychoactive medication.
