Panic attacks linked to heart disease

New research suggests that people who suffer from panic attacks are at increased risk of developing heart disease.

Dr Kate Walters and colleagues at University College London examined medical records of more than 400,000 people, including 57,615 who had been diagnosed with panic attacks. Results showed that people who were younger than 50 when they were first diagnosed with panic attack were 38% more likely to have a heart attack and 44% more likely to develop heart disease than those without the condition. Those who were older than 50 at the time of diagnosis did not have an increased risk of heart attack, but were 11% more likely to develop heart disease than those without the condition.

Intriguingly, the results also showed that whilst panic attack sufferers were at increased risk of developing heart disease, they were seemingly less likely to die from it.

Why people who suffer from panic attacks should be at increased risk of developing heart disease is unclear. The study authors put forward several theories, one being that panic disorders might trigger nervous system changes which could promote the clogging of arteries. Another theory is that people may have been misdiagnosed as having panic attacks when they actually have coronary heart disease. “Clinicians should be vigilant for this possibility when diagnosing and treating people presenting with symptoms of panic," said Dr Walters.
