Types of aortic valve problems

Published January 1, 2022

In aortic stenosis, the heart's aortic valve narrows and can't open fully. In aortic regurgitation, the valve doesn't close properly. The cause may be present at birth (congenital) or acquired later in life, and the problems can occur alone or together.

Adding ultrasound to mammography improves cancer detection rate

Published November 1, 2021

A combination of mammography and ultrasound may increase accuracy of breast cancer screening.

If it’s not breast cancer, should you worry?

Published November 1, 2021

Most breast lumps are not cancerous. Some 80% of biopsies are negative. But some women develop noncancerous breast conditions that may raise their risk of a future cancer. For women with these conditions, doctors may recommend additional monitoring. This might include additional screenings, or screenings using other technology, such as MRI or breast ultrasound.

From the wrist to the heart: A safer route for angioplasty?

Published November 1, 2021

At least half of all artery-opening angioplasties done in the United States now begin at the wrist instead of the top of the thigh. The wrist (or transradial) approach is easier on patients, safer, and less expensive. After the procedure, people can sit up right away instead of lying flat for several hours, and they are much less likely to experience bleeding, including serious bleeding in the abdomen. The lower complication rates mean people can leave the hospital sooner, which translates to decreased costs.

You don't say? Brain space

Published October 1, 2021

It’s thought that the average person uses just 10% of the brain. While some parts of the brain may be more active at any given time or during a particular activity, there is no part that is known to be unused or completely unnecessary.

Do BMI numbers add up?

Published October 1, 2021

For decades, researchers have used body mass index (BMI) to estimate a person’s body fat mass and predict possible health risks. While BMI is helpful, it can’t accurately measure the type of fat people accumulate, especially among older adults. Monitoring one’s waist size with a simple measuring tape may be a better option.

Radiation risk from medical imaging

Updated September 30, 2021

Given the huge increase in the use of CT scans, concern about radiation exposure is warranted. Patients should try to keep track of their cumulative radiation exposure, and only have tests when necessary.

A closer look at heart disease risk

Updated September 21, 2021

Sometimes the presence of atherosclerosis, the disease underlying most heart attacks, is not clear or easily recognized, especially before a heart attack or other crisis happens. In those instances, doctors may rely on a coronary artery calcium (CAC) scan, which measures the amount of calcium in the heart's arteries, high levels of which are associated with cardiovascular disease. The CAC results can help predict a person's risk for heart attack or stroke, even if that person doesn't have obvious risk factors or symptoms.
