Cardiology experts who analyzed three sets of hypertension guidelines told an international conference all of the documents agreed on most major issues. The investigators also found, however, many guidelines included in the three documents were not based on the highest levels of evidence.
An FDA-approved, 150 g barium sulfate and bismuth oxide cap protects interventional cardiologists from radiation exposure, according to a poster presented at the SCAI Scientific Sessions. The study used data from dosimeters placed on the inside and outside of the caps on the left and right sides and in the center during an average of 50 procedures each by fellows and attending clinicians. The results show that the left side of the head receives significantly more radiation than the right, that the cap is protective and that the primary operator receives less overall radiation than the supervising clinician.
Women who suffered pregnancy complications including preeclampsia and those who have a systemic autoimmune collagen-vascular disease are considered at risk for cardiovascular disease under 2011 American Heart Association guidelines for CVD prevention, writes Dr. C. Noel Bairey Merz. The developments reflect increased understanding of CVD in women, but more work must be done, Merz writes. Future guidelines may incorporate recent data such as research confirming women who have had their ovaries removed as a prophylactic measure face heightened risks, she writes, and EHR technology would ensure cardiologists can connect the dots in women's health histories.
Researchers discovered that a gene called Tbx3 may interfere with cardiac conduction, potentially causing heart arrhythmia. The study, published in the Proceedings of the National Academy of Sciences, showed that increasing Tbx3 protein resulted in irregular heartbeat or sudden death in mice.
St. Louis-based CardiaLen has obtained $2.4 million in a funding round. The startup is preparing to conduct clinical studies of an implantable device that the company says can allow patients with atrial fibrillation to receive pain-free cardioversion treatment.
