QTc changes and early major adverse cardiovascular events associated with antidepressant treatment for major depressive disorder in adults: individual participant data network meta-regression of double blind randomised trials.

Escitalopram and amitriptyline significantly prolong QTc intervals in adults with depression, with effects varying widely among individuals, but no increase in early cardiovascular events.

• Why it matters: Understanding how antidepressants impact heart rhythm and cardiovascular risk is crucial for safe treatment, especially since depression treatments can carry potential cardiac side effects.
• What they did: The study analyzed data from 35 trials with 8,679 participants, comparing 10 antidepressants and placebo, focusing on QTc changes and early major adverse cardiovascular events using network meta-regression and meta-analysis.
• The result: While escitalopram and amitriptyline increased QTc intervals, no link was found between antidepressant use and higher rates of early cardiovascular events, emphasizing the importance of individualized risk assessment in treatment decisions.
