From the methods section of the abstract: “We excluded post-fibrinolysis patients, patients with old stents, and those who presented more than 24 hours
after the onset of pain.”[edit: I misread the PDF version which included multiple abstracts, the methods I’m referring to was from a separate study with the title cutoff, this specific abstract didn’t specify. But from below and table 1 in:
https://jamanetwork.com/journals/jama/article-abstract/20140... which looked at 68,000 STEMIs, 3.1% presented > 12 hours and 8.4% had an unknown time of symptom onset. Wouldn’t explain the magnitude of effect seen in this study. Circadian effects on STEMI and increased incidence on Monday are not new observations.]
Don’t think late presentation STEMIs are that common to begin with for your argument to have logical sense, this is the worst form of a “heart attack”.
From this single center study presentations > 12 hours only comprised 10%.
