A Double-Blind, Placebo-Controlled Study of Escitalopram in the Prevention of Depression in Patients With Acute Coronary Syndrome
A Double-Blind, Placebo-Controlled Study of Escitalopram in the Prevention of Depression in Patients With Acute Coronary Syndrome
Objective: To evaluate the efficacy of preventive treatment with a selective serotonin reuptake inhibitor (SSRI) (escitalopram) in the first year after acute coronary syndromes (ACS).
Methods: 240 patients with acute coronary syndromes (ST-elevation myocardial infarction [STEMI]), non-STEMI or unstable angina) will be enrolled within 8 weeks after ACS and will be randomly assigned to treatment with escitalopram/placebo (5-20 mg) in 52 weeks. Primary outcome measures are the diagnosis of depression and HDS (Hamilton Depression Scale). Psychiatric measurements: SCAN (Schedules for Clinical Assessment in Neuropsychiatry), HDS, HAS (Hamilton Anxiety Rating Scale), Udvalg for Kliniske Undersogelser (UKU) Side Effect Rating Scale, ESSI (Enhancing Recovery in Coronary Heart Disease [ENRICHD] Social Support Instrument), SF-36 (Short Form-36 Health Survey), SCL-92 (Symptom Check List) and BDI (Beck´s Depression Inventory). Cardiological measurements are blood pressure, electrocardiography, echocardiography (left ventricular ejection fraction), heart rate variability and use of medicine.
Discussion: ACS patients with mental illness are usually only diagnosed to a very small extent during admission in a cardiologic department. These patients mainly remain untreated with an increased risk of somatic comorbidity and mortality. Therefore, it is in accordance with ethical principles to conduct a double blind, placebo-controlled study investigating the interface between anxiety, depression and ACS. Even in this blinded study, where one of the groups are treated with placebo, there will be a higher degree of treatment of depressive symptoms due to the low recognition of this problem.
Conclusion: The DECARD study is the first study evaluating the effect of prophylactic treatment of depression in patients with ACS. The study will show if prophylactic treatment will improve cardiac prognosis.
