Latest CT Scanners Detect Blocked Arteries

Doctors are hoping the results of a new study led by Johns Hopkins University will pave the way for standardized noninvasive imaging of coronary arteries by using newer, more powerful CT scanners. Currently, angiograms are considered the gold standard for detecting blockage of arteries in the heart. However, angiograms (also called cardiac catheterization) are invasive procedures with many risks. CT scans, on the other hand, carry less risks and are noninvasive. Researchers have found that 3D scans produced by CT scanners can accurately pinpoint the size and location of blockages, but not nearly as well as a traditional angiograms. Additional studies will be needed to clarify exactly how this technology can be best used in the detection of coronary heart disease.

Same-sex Heart Transplants Improve Outcome

Are men and women truly different at heart? Perhaps, when it comes to heart transplants. A new Johns Hopkins University study finds that cardiac transplant patients have better odds of survival and a lower risk of rejection if they receive organs from donors of the same sex. Doctors think that heart size is an important factor. Men’s hearts are bigger and have more pumping capacity than women’s. Researchers believe that hormonal and immunologic differences between the sexes may also play a role. However, at this time it is not feasible for every person in need of a heart transplant to be paired with a perfect match – approximately 2,700 Americans are waiting for a heart, but only 2,200 heart transplants are performed annually.
