Canadians who live in low-income neighbourhoods are more likely to have a heart attack than their wealthier counterparts, a new report indicates.

But  their quality of care in hospital seems to be about the same, finds a new report released by the Canadian Institute for Health Information.

Almost 67,000 Canadians landed in hospital due to a heart attack in 2008-09.

A breakdown of five neighbourhood income levels found that those in the least-affluent areas were 37 per cent more likely to have a heart attack than those in the most-affluent districts.

The report says the risk of dying in hospital within 30 days was about the same for all socio-economic groups, averaging 8.3 per cent. However the most affluent patients were seven per cent more likely than the least affluent to have a procedure such as angioplasty or bypass surgery.

"Medical literature indicates that not every patient is selected for or would benefit from such a procedure," the report said.

Heart attack rates were at a high of 347 per 100,000 in Newfoundland and Labrador and a low of 169 per 100,000 in British Columbia, after population age differences were taken into account.

The CIHI researchers said addressing gaps in heart health between socio-economic groups and geographic areas in Canada could help improve the health of the population.

The Health Indicators 2010 report included an estimate of cost savings if all socio-economic groups had a heart-attack rate like that of the most affluent neighbourhoods.

"The overall rate of hospitalized heart attacks would have decreased by approximately 16 per cent, or the equivalent of about 10,400 hospitalized heart attacks," the report said.

"Based on 2007-2008 cost data, this represents an estimated potential savings in hospital costs of about $100 million, not including physician fees."
