Antidepressants May Not Raise Heart Attack Risk
Underlying Depression May Be the Problem, Says British Study
Heart Attack Risk Subsides
Antidepressants were associated with an increased risk of heart attacks. But it wasn't quite that simple.
Taking all risk factors into account, both tricyclic antidepressants and SSRIs were associated with an increased risk of a person's first heart attack. But the risk was higher for the first 28 days on either type of antidepressant. After that, the risk subsided, rising again for 29-56 days after the patients stopped taking antidepressants.
"Reassuringly ... there was no increased risk of [heart attack] with prolonged antidepressant exposure," says the study.
The researchers say they're not sure why the risk rose after patients stopped taking the drugs. They say it could be due to the drugs, but it could also be that patients quit the drugs as their heart problems worsened or developed other illnesses. More work is needed to sort that out, say the researchers, who included Laila Tata of England's Nottingham City Hospital.
Their study appears in the April edition of the journal Heart.
