COVID-19 quarantine and depression in patients with congenital heart disease.

COVID-19 outbreak has brought tremendous psychological pressure to the general population, especially to those with associated cardiovascular disease. An online Patient Health Questionnaire (PHQ-9) survey on consecutive congenital heart disease (CHD) patients, was carried out to determine depression during the Spanish coronavirus disease (COVID-19) quarantine. Two-hundred forty-two out of 407 (59%) CHD patients answered the survey, 123 (51%) had mild defects, 88 (36%) moderate and 31 (13%) great defects, most of them between 18 and 24 years old and 51% were male. Patients were dichotomized to no or mild (PHQ-9 < 10) and moderate to severe (≥ 10) depressive symptoms. Thirty-four (14%) patients showed a PHQ-9 ≥ 10 and 10 of them (29%) were under anxiolytic or antidepressant treatment during the quarantine. During the study period, 9 (4%) patients had COVID-19 symptoms. Patients with a NYHA above 2 (P=0.025), living in houses without garden or balcony (P=0.014), needing psychological/psychiatric evaluation/medication in the previous 12 months or being under anxiolytic/antidepressant treatment during the confinement had, significantly, a PHQ-9 score ≥ 10 (P < 0.001). Being under anxiolytic/antidepressant treatment during the coronavirus pandemic [OR 3.92 (95% CI 1.05-14.66), P=0.043] and having previous psychological/psychiatric evaluation in the previous 12 months to the quarantine [OR 3.82 (95% CI 1.16-12.54), P=0.027] were the only variables that reached statistical significance, in the multivariable analysis, as predictors of a pathological PHQ-9 questionnaire (score ≥ 10). In conclusion depression was frequent during the COVID-19 quarantine among CHD patients, with only a third of them being under anxiolytic or antidepressant treatment. Needing psychological/psychiatric evaluation/treatment during the previous 12 months to the lockdown was a predictive factor for an abnormal PHQ-9 score.
