[Predisposition to Psychological Distress in Patients After Coronary Bypass Surgery: Relation to One Year Prognosis]

to assess effect of type D personality (TDP) on one year prognosis after coronary artery bypass grafting (CABG).

Personality type was evaluated using the DS-14 scale in 683 patients before and in 1 year after CABG; 152 patients had TDP, 531 had not. After 1 year of follow-up we assessed functional class of angina and chronic heart failure, and registered cardiovascular complications (CVC): deaths, myocardial infarctions, strokes, amputations, thromboses of arteries of lower extremities, hospitalizations, requirements in repetitive angiographies of coronary grafts. Rate of development of combined end point comprising all these events was also evaluated.

During follow-up CVC developed more often in patients with TDP compared with those without TDP (31.8 and 14.6%, respectively, =0.049). According to multifactorial regression analysis TDP was independently associated with 3.21 fold increase in risk of CVC.

Detection of TDP after CABG is advisable for conducting subsequent interventions directed at improvement of long term results of treatment.
