Significant financial stress associated with 13-fold higher odds of having a heart attack

Significant financial stress is associated with a 13-fold

higher odds of having a heart attack, according to research

presented at the 18th Annual Congress of the South African

Heart Association.

‘The role of psychosocial factors in causing disease is a

neglected area of study in South Africa, perhaps because

there are so many other pressing health challenges such

as tuberculosis and HIV,’ said lead author Dr Denishan

Govender, associate lecturer, University of theWitwatersrand,

Johannesburg.

‘The INTERHEART study showed that psychosocial

factors are independently associated with acute myocardial

infarction (heart attack) in Africa but as far as we are aware

there are no other published local data,’ said last author

Professor Pravin Manga, professor of cardiology, University

of the Witwatersrand.

This study included 106 patients with acute myocardial

infarction who presented to a large public hospital in

Johannesburg. A control group of 106 patients without cardiac

disease was matched for age, gender and race. All participants

completed a questionnaire about depression, anxiety, stress,

work stress and financial stress in the previous month. The

Likert scale was used to grade the experience of each condition.

Regarding financial stress, patients were graded with no

financial stress if they were coping financially; mild financial

stress if they were coping financially but needed added support;

moderate financial stress if they had an income but were in

financial distress; and significant financial stress if they had no

income and at times struggled to meet basic needs. Levels of

psychosocial conditions were compared between groups and

used to calculate associations with having a heart attack.

Self-reported stress levels were common, with 96% of

heart attack patients reporting any level of stress, and 40%

reporting severe stress levels. There was a three-fold increased

risk of myocardial infarction if a patient had experienced

any level of depression (from mild to extremely severe) in the

previous month compared to those with no depression.

Both work stress and financial stress were associated

with a higher risk of acute myocardial infarction. The odds

of myocardial infarction was 5.6 times higher in patients

with moderate or severe work stress compared to those with

minimal or no stress. Patients with significant financial stress

had a 13-fold higher odds of having a myocardial infarction.

Dr Govender said: ‘Our study suggests that psychosocial

aspects are important risk factors for acute myocardial

infarction. Often patients are counselled about stress after

a heart attack but there needs to be more emphasis prior to

an event. Few doctors ask about stress, depression or anxiety

during a general physical and this should become routine

practice, like asking about smoking. Just as we provide advice

on how to quit smoking, patients need information on how

to fight stress.’
