The advent of increasingly sensitive cardiac troponin assays probably makes cardiac ischemia increasingly questionable as the true cause of a hospitalization for chest-pain symptoms without biochemical evidence of myocyte injury.
“The advent of increasingly sensitive cardiac troponin assays probably makes cardiac ischemia increasingly questionable as the true cause of a hospitalization for chestpain symptoms without biochemical evidence of myocyte injury.27”
From Evolocumab and Clinical Outcomes in Patients with Cardiovascular Disease (2017) · cites this paper as [27]
The Conclusions (page unavailable) say that more sensitive troponin assays have reduced the proportion of patients classified as having unstable angina and that it is unclear whether acute coronary syndrome events occur without some troponin increase. That supports questioning an acute coronary syndrome diagnosis when sensitive testing shows no increase, but the paper does not extend that inference to cardiac ischemia as the cause of every chest-pain hospitalization; it also discusses angina without myocardial infarction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
