Severe mental illness linked to higher death rate after heart attack
People with a severe mental illness are more likely to die following a heart attack than those without a psychiatric diagnosis, new research has suggested.
Experts at the University of Edinburgh examined anonymous hospital data for more than 235,000 people admitted for heart attack in Scotland from 1991 to 2014.
They compared the risks of death and further heart attack and stroke among heart attack patients with schizophrenia, major depression or bipolar disorder to patients without a history of mental illness.

After 30 days, patients with schizophrenia were twice as likely to have died and patients with bipolar disorder or major depressionhada30percent-50 percentincreasedriskofdeath.
People with severe mental illness were also less likely to receive revascularisation - an operation to restore blood flow - which researchers say may indicate differences in care.
Researchers say the findings may be due to a number of reasons including poor general health, social exclusion and possible differences in longerterm treatment, and are calling for disparities to be urgently addressed.
Dr Caroline Jackson, lead researcher at the University of Edinburgh's Usher Institute, said: "This study highlights marked and persistent mental health inequalities in heart attack outcomes in Scotland.
"The underlying reason is likely to be multifactorial and complex, and remains poorly understood.

The researchers found no evidence of any improvement across the 24-year period up to 2014 examined in the study.
They advise that people with mental health conditions should continue to seek advice from their medical team if they have any concerns about their health.
