CT angiography and stress tests can predict heart attacks

Invasive angiography unnecessary?

Noninvasive CT angiography and CT myocardial stress perfusion imaging can adequately predict heart attacks and major adverse cardiovascular events, according to a study published yesterday in Radiologyno invasive coronary angiography (ICA) required.

Invasive coronary angiography (ICA), along with stress tests and single photon emission tomography (SPECT) imaging, has long been the "gold standard" for making determinations of whether a lesion is hemodynamically significant and likely to result in major adverse cardiovascular events, reads a Radiological Society of North America press release.

But this "gold standard" has its drawbacks—in costs and risk.

AACC scientists identify new cardiac biomarker

Plus, get ready for high sensitivity cardiac Troponin assays in practice.

Laboratory medicine experts discovered a new lipid biomarker panel to detect heart failure with reduced ejection fraction (HFrEF) even before symptoms present, with "much greater certainty than standard tests for this condition," according to a January 5 press release from the American Association for Clinical Chemistry (AACC).

The January issue of the AACC's journal, Clinical Chemistry focuses on cardiovascular disease and features research reflecting a "growing understanding of the molecular signatures of heart disease," according to the press release, and a trend towards developing "more precise tests for the early diagnosis, monitoring, and targeted treatment."

The study in question identified three new cardiac lipid biomarkers, a cardiac lipid panel (CLP), which "significantly improved diagnostic performance" when combined with the current standard biomarker approach for diagnosing heart failure, NT-proBNP.
