nly when symptomatic or if their hemoglobin levels dropped below 8 g/dL, a more restrictive strategy. For patients in the liberal transfusion strategy group, 4.3 percent of patients had a heart attack, unstable angina, or died in the hospital; whereas, 5.2 percent of patients on the restrictive transfusion arm had either a heart attack, unstable angina, or died in the hospital, a difference that was not statistically significant. Although anemia occurs in most patients with hip fracture, many of whom are women, the data emerging from the analysis of this study indicate that transfusion in the absence of symptoms is not always required. Appropriate use of blood transfusions assures more efficient use of the Nation's blood supply. NHLBI Spokesperson: Simone Glynn M.D., MPH. Study Investigator: Jeffrey L.

Air pollution impacts blood-vessel health. (Embargoed until 2 p.m. EST, Monday, Nov. 16.)Results from the Multi-Ethnic Study of Atherosclerosis (MESA) and Air Pollution Study confirm that air pollution appears to have short- and long-term ill effects on the health and resiliency of blood vessels. The researchers used ultrasound-guided measurements of blood-vessel diameter and responsiveness in 3,501 people participating in the ongoing MESA study, a long-term population-based study of ethnically diverse Americans in six urban U.S. regions. The researchers recorded air pollution levels in these locales the day before the blood vessel measurements were taken and estimated annual exposure to fine particulate air pollution. The results link long-term exposure to air pollution with both forearm-artery narrowing and a reduced ability of these arteries to adjust to normal changes in blood flow. In contrast, short-term exposure to air pollution
