Does antidepressant pharmacotherapy increase the risk of mortality in patients with acute coronary syndrome?
In a real-world cohort of ACS patients, antidepressant use was associated with a 2-fold increased risk of all-cause and cardiovascular mortality at 1 year, highlighting the need for careful management and individualized therapy.

Abstract Background Antidepressant pharmacotherapy (ADP) has been related to increased cardiovascular risk and its use among acute coronary syndrome (ACS) patients remains controversial. Purpose The aim of the study was to evaluate prevalence and outcome of antidepressant treatment in a real-world cohort of ACS patients. Methods We sought to assess the prevalence of established ADP and its impact among ACS patients admitted to four Swiss University Hospital enrolled in the prospective multicenter SPUM registry. The primary endpoint was all-cause mortality. The association between ADP and mortality was tested by adjusted multivariable conditional logistic regression. Results Out of 4’787 ACS patients, 317 patients (6.6%) had ADP. Compared with the overall population, ADP patients were more likely to be younger (65.1±12.2 vs 66.9±11.8, p=0.015), of female sex (34.7% vs 22.5%, p0.001) and smokers (40.4% vs 31.0%, p=0.001). They presented less frequently with hypertension (63.0% vs 75.5%, p0.001) and alcohol consumption (43.2% vs 55.2%, p0.001). Secondary prevention therapy with aspirin (37.9% vs 45.0%, p=0.009) or angiotensin receptor antagonists (24.1% vs 31.8%, p=0.003) was less prescribed in ADP patients and they presented with a slightly increased glomerular filtration rate (82.1±21.5 vs 79.5±21.9, p=0.05). At 1 year follow-up, ADP patients experienced an almost 2-fold risk of all-cause mortality and cardiovascular (CV) mortality. This enhanced risk persisted after adjustment for confounding significant baseline characteristics for all-cause mortality (Adjusted HR 2.1, 95%CI 1.4-3.2, p=0.001, Figure 1) and CV mortality (Adjusted HR 2.1, 95%CI 1.2-3.5, p=0.007, Figure 1). Conclusions Among a real-world cohort of ACS-patients, ADP is associated with a significant increased rate of all-cause mortality and CV mortality. These observations may in part be related to their less favorable clinical phenotype and a less optimal management of their condition. Clinicians should be aware to these findings, assure equally optimal treatment in such patients and further individualize ADP, employing newer and safer ADP.Cumulative survival
Denegri et al. (Sat,) conducted a cohort in acute coronary syndrome (ACS) (n=4,787). Antidepressant pharmacotherapy vs. No antidepressant pharmacotherapy was evaluated on all-cause mortality (Adjusted HR 2.1, 95% CI 1.4-3.2, p=0.001). Antidepressant pharmacotherapy in patients with acute coronary syndrome was associated with an increased risk of all-cause mortality at 1 year (Adjusted HR 2.1; 95% CI 1.4-3.2; p=0.001).
