WEDNESDAY, Dec. 12, 2018 (HealthDay News) — Because of greater patient delays from symptom onset to first medical contact, female patients with ST-segment elevation myocardial infarction (STEMI) experience greater total ischemic time than male patients, according to a study recently published in the European Heart Journal: Acute Cardiovascular Care<\/i>.<\/p>\n
Matthias R. Meyer, M.D., from Triemli Hospital in Zurich, and colleagues compared patient delay (symptom onset to first medical contact) and system delay (first medical contact to percutaneous coronary intervention-facilitated reperfusion) between 967 women and 3,393 men in a STEMI treatment network. Trends were analyzed from 2000 to 2016, with additional comparisons between three periods (2000-2005, 2006-2011, and 2012-2016).<\/p>\n
The researchers observed an independent association for female gender with greater patient delay (P = 0.02 versus men), accounting for a 12 percent greater total ischemic time among women in 2012 to 2016 (median, 215 minutes for women versus 192 minutes for men; P < 0.001). Median system delay was reduced by 18 and 25 minutes in women and men, respectively, from 2000-2005 to 2012-2016 (P < 0.0001 for trend; P = not significant for gender difference). In men but not women, total occlusion of the culprit artery, stent thrombosis, a Killip class of 3 or greater, and presentation during off-hours predicted delays.<\/p>\n
“In this contemporary analysis of a large STEMI treatment network, women and men experience equal reductions in system delays, yet women continue to have greater patient delays that have remained unchanged for more than a decade,” the authors write.<\/p>\n
