Test Diagnoses Preeclampsia Earlier; Aspirin Reduces Risk


Laurie Barclay, MD

Sept. 27, 2002 — Two studies presented on Sept. 26 at the American Heart Association 56th Annual High Blood Pressure Research Conference in Orlando, Florida, offer good news for early detection and prevention of preeclampsia. The first verifies the utility of a tolerance-hyperbaric test (THT) that finds gestational hypertension and preeclampsia 23 weeks earlier than would be suspected clinically. The other study shows that aspirin given at bedtime, but not in the morning, significantly reduced the risk of developing preeclampsia.

The THT “is the first test that provides such high degrees of sensitivity and specificity at such a low gestational age,” lead author Ramon C. Hermida, PhD, from the University of Vigo in Spain, says in a news release. “The price of the equipment is insignificant compared to the cost of just one preterm delivery caused by preeclampsia.”

Compared with stents, coronary artery bypass graft (CABG) reduced the rate of revascularization procedures in patients with coronary artery disease (CAD), according to results of the multicenter Stent or Surgery (SoS) trial reported in the Sept. 28 issue of The Lancet. Although a secondary outcome assessment also suggested lower frequency of death with CABG than with stents, this study took place before the use of drug-eluting stents.

Earlier this week at the 14th annual Transcatheter Cardiovascular Therapeutics (TCT)

symposium, investigators from the SIRIUS trial reported favorable final results for the sirolimus-eluting stent.
