Commonly prescribed drugs used to lower blood pressure can actually have the opposite effect—raising blood pressure in a statistically significant percentage of patients. A new study by researchers at Albert Einstein College of Medicine of Yeshiva University suggests that doctors could avoid this problem—and select drugs most suitable for their patients—by measuring blood levels of the enzyme renin through a blood test that is becoming more widely available. The study appears in the online edition of the American Journal of Hypertension.

Dr. Amar Sethi, VP of Science and Technology at Pacific Biomarkers, Inc, observed that in ischemic heart disease patients untreated with statins, there is a difference in the way bad cholesterol is removed from the body by the HDL particle. They found that a particle called pre-β1 HDL is increased, while LCAT—the enzyme that packs cholesterol into the core of the HDL particle—is reduced.
Vitamin D deficiency is associated with arterial stiffness, a risk factor for heart disease and stroke, in black teens according to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM). Black teens taking vitamin D supplementation of 2,000 international units (IU) per day had a decrease in central arterial stiffness.

A new study published online today by JAMA shows that among patients age 65 years and older, rosiglitazone (a medication for treating Type 2 diabetes) is associated with an increased risk of stroke, heart failure, and all-cause mortality (death) when compared with pioglitazone (another medication for diabetes). The study was published online today in advance of an upcoming Food and Drug Administration meeting that will review the safety of rosiglitazone. The paper will appear in the July 28 print issue of JAMA.
A new study done by researchers at Wake Forest University Baptist Medical Center indicates that chest pain may no longer have to mean a hospital stay – there is another option for diagnosing heart-related chest pain that costs less and, in some cases, allows the patient to return home the same day.
Researchers at UT Southwestern Medical Center have pinpointed a set of biological mechanisms through which estrogen confers its beneficial effects on the cardiovascular system, independent of the hormone’s actions on cancer.

New research from NYU Langone Medical Center shows that a simple, inexpensive and noninvasive carotid artery ultrasound of the neck can be used as a preliminary diagnostic tool for coronary artery disease (CAD). This may be an alternative to the standard, expensive and more invasive coronary angiography. The ultrasound test can also be used to rule out the diagnosis of CAD in patients presenting with reduced heart pump function.
