Pregnancy Increases Heart Attack Risk in Women
"Our initial report indicated a mortality rate of 20 percent, and nearly 40 percent was reported by other studies. In contrast, the new data suggest that only 5 percent to 10 percent of expectant and new mothers who have a heart attack die as a result," he added.
The gives credit to increased awareness, more aggressive clinical approaches to treating AMI in general, including standardized hospital protocols for screening and diagnosis, as well as the application of these approaches to pregnant women.
"Interestingly, the mechanism of AMI is somewhat different when it occurs in association with pregnancy. One in four women had a weakening and separation of the walls of the coronary arteries (coronary dissection), which is a rare cause of heart attack in the general population," explains Dr. Elkayam.
"Another 13 percent had normal coronary arteries. These findings signify the need to establish the cause of AMI in pregnancy in order to decide on appropriate therapy."
Dr. Elkayam said that those who experienced AMI within 24 hours before or after delivery are twice as likely to die from heart attack as those who have a cardiac event before labour or postpartum (24 hours to three months after delivery).
He hopes that guidelines presented in the paper will further increase awareness about AMI in pregnancy.
The study is published in the July 15, 2008, issue of the Journal of the American College of Cardiology.
