People from lower socioeconomic backgrounds who suffer a heart attack come to the emergency department more often, are less likely to be treated aggressively and have higher mortality rates a year after the attack, says new University of Alberta research that has important implications for access to cardiac care.
Dr. Padma Kaul and a group of U of A researchers investigated 5622 patients in Alberta who went to a hospital emergency department with a first heart attack. Following the common practice of using the neighbourhood median household income as a proxy for socioeconomic status, the researchers classified patients into separate income groups. Patients in the lowest income quartile were more likely to be older, female and to have other illnesses such as diabetes and peripheral vascular diseases. Researchers first looked at who was more likely to have an angioplasty or coronary bypass surgery and then did a one-year follow-up after the emergency department visit to see whether the patient was still alive. The study is published in the January 2007 issue of the prestigious American Journal of Medicine.
"We found a clear discrepancy when it comes to socioeconomic status," said Kaul. "We may have equal access health-care coverage in Canada but the bottom line is that people may not be getting equal treatment."
