The differences in the change of hope life can be due to disparities in care
Women and black patients lose more years of their expected life after heart attack compared with whites, according to a study published in the Journal of the American College of Cardiology.
Previous research has looked at gender and racial differences in survival after a heart attack, but this was the first study to account for the hope of longer life of women in the general population and lower life expectancy of blacks.
“It is imperative that we understand whether differences we observe in a specific group, such as people with heart attacks, is special to them or, more broadly reflect the experience in the population,” said Harlan Krumholz, MD, FACC, the author main study and director of the Center hospital Yale-New Haven Outcomes Research and evaluation. “We found that women and black patients are losing more years of his life after a heart attack one of the reasons potentially be they are not getting the attention on par with men and white patients. The study clearly establishes the disadvantage of these groups and suggests that increasing the quality of care for everyone could be a useful remedy. ”
The researchers used data from Project Cooperative Cardiovascular, a prospective cohort includes all service fee Medicare beneficiaries discharged from US hospitals nongovernmental intensive care with a heart attack diagnosis in mid 1990s.
“Previous research has shown that women and men have similar mortality after a heart attack,” said Emily Bucholz, M.P.H., lead author of the study and a pediatric resident at Children’s Hospital Boston. “Recognizing that women in the general population live longer than men, we ask the question of whether women who have a heart attack are actually survival at a disadvantage because they are losing more years of life after the fact that men . ”
The study authors reviewed the records of 146, 743 heart attack patients. Overall, 48.1 percent of patients were women and 6.4 percent were black. Women and black patients had a higher prevalence of diabetes hypertension and heart failure compared to white men. One limitation of the study was that black patients represented a small part of the cohort of this type.
After 17 years of follow-up, the survival rate was 8.3 percent for white males, 6.4 percent for white women, 5.4 percent for black men and 5.8 percent for black women. However, when adjusted for differences in survival expected, women lost significantly more years of life than men. Researchers estimate that, on average, a white man of 65 years old, lost 5.1 years of life after a heart attack and a white woman loses 10 years, which translates into a reduction of 29 percent in the remaining life for men and a reduction of 41 percent for women.
Black men lost 0.3 years longer than white men and black women lost another year of life than white women, equivalent to black patients lose 5 percent of their white patients life. According to the researchers, racial differences in life expectancy can be explained by differences in comorbidities and treatment utilization. This was not the case for women. After adjusting for differences in clinical presentation and treatment, women still lost more of his life than men.
“The role again reminds us that we need to study further the reason for the disparity in life expectancy for patients female and black sex – both in our clinical practice and our research,” said JACC Editor-in- chief Valentin Fuster, MD, Ph.D., MACC.
