This network meta-analysis evaluated the impact of various antidepressants on QTc interval and early major adverse cardiovascular events (MACE) in adults with major depressive disorder. Among 8679 participants, escitalopram and amitriptyline were linked to significant QTc prolongation (8.7 ms and 5.3 ms, respectively). However, no association was found between antidepressant use and early MACE compared to placebo.
Key findings
- Escitalopram and amitriptyline increased QTc intervals by 8.7 ms and 5.3 ms, respectively.
- Amitriptyline and escitalopram showed the highest QTc prolongations at 58.8% and 21.3%.
- Venlafaxine and vortioxetine were associated with the lowest QTc intervals at 24.1% and 9.7%.
- No association was found between antidepressant use and early MACE (risk difference 0.01%).
Why it matters
Understanding the cardiovascular effects of antidepressants is crucial for clinicians to make informed treatment decisions, particularly in patients with pre-existing cardiovascular conditions. This study highlights the importance of considering individual risk factors when prescribing.
