(August 26, 2009 - Insidermedicine) From New Haven - According to research in the Journal of the American College of Cardiology, many patients who undergo percutaneous coronary intervention are readmitted. In a study of nearly 300,000 patients who underwent PCI, researchers found that about 15% were readmitted within 30 days of discharge. Those who were readmitted were also more likely to die within 30 days than those who were not.

From Seattle - According to a study in the journal Cancer Research, tamoxifen may increase the risk of some forms of breast cancer. In a study of over 360 breast cancer survivors, researchers found that those who took tamoxifen for secondary prevention had a 4.4 times higher risk of estrogen receptor-negative contralateral breast cancer. However, the researchers caution that these findings don't substantially change the risk-benefit ratio for tamoxifen.

And finally, from Alabama - According to research in the journal Neurology, high diastolic blood pressure may be linked to cognitive problems. In a study of nearly 20,000 people, researchers found that in those aged 45 and older, every 10-point increase over 90 mm Hg was associated with a 7% higher risk of cognitive problems. This association was not found with systolic pressure.
