Cervical artery dissection, a rare but potentially devastating cause of stroke, is a tear in the lining of one of the main arteries that carry blood to the brain. Any sudden, jerky neck movements, including chiropractic neck adjustments and whiplash from a car accident, can cause such a tear. Cervical artery dissections also have been reported after strenuous weight lifting, tennis, head-flinging dance moves, yoga, and roller coaster rides. The dissections occur in only about three in 100,000 people per year, but they are one of the most common causes of stroke in younger people.

Prices for six common heart tests and procedures at top-ranked U.S. hospitals showed surprisingly wide variations, according to a 2022 Harvard study. There was a 10-fold difference in the median prices patients pay for a heart ultrasound, and even larger disparities for procedures such as implanting a pacemaker. The differences may reflect power dynamics between hospitals and insurance companies. For both entities, factors such as location, size, and popularity influence that dynamic — which, in turn, affects the market dynamics that dictate costs.

A long, leisurely meal like Thanksgiving can be a good opportunity to practice mindful eating. Being mindful simply means bringing close attention and awareness to the present moment, without judgment.

Listening to music (or singing or playing an instrument) may benefit cardiovascular health. Evidence suggests music helps rebalance the nervous system to promote the relaxation response and dampen the stress response. The benefits may result from greater heart rate variability, enhanced exercise performance, lower stress hormone levels, or reductions in blood pressure.

The American Heart Association revamped its online tool, My Life Check, designed to help people prevent cardiovascular disease. Along with other changes, the AHA added healthy sleep duration to the list of seven other factors assessed by the tool. Those factors are maintaining a healthy weight, not smoking, being physically active, eating a healthy diet, and keeping blood pressure, blood sugar, and cholesterol at acceptable levels. Each factor (now known as Life's Essential 8) are scored on a scale of 1 to 100 and used to generate a composite cardiovascular health score.

Elevated LDL cholesterol contributes to cardiovascular disease. Taking statin drugs can substantially lower this risk. But what if a person's LDL level remains too high on their maximally tolerated dose? An expert consensus report lays out a clear path for next steps.

Older adults exposed to light while sleeping at night may be more likely to have obesity, high blood pressure, and diabetes compared with adults who sleep in darkness.

Cardiac rehabilitation, which teaches heart-healthy habits coupled with supervised exercise, can help people with heart conditions prevent future problems. Some parts of the program can be done at home, delivered through a computer, tablet, or smartphone. Known as virtual cardiac rehab, this approach offers several advantages over conventional rehab, such as avoiding the time and expense of traveling to multiple sessions during the week.

Vascular dementia, which arises from longstanding, cumulative damage to small blood vessels in the brain, may cause or contribute to up to half of cases of dementia. The vessels may thicken or become blocked by blood clots, causing tiny strokes that damage specific parts of the brain important for various thinking abilities. Keeping blood pressure in the recommended range of 120/80 or lower is the best way to prevent vascular dementia.

Anti-clotting medications have a well-known and fairly common effect: a heightened risk of bleeding. Being older, having certain health conditions, and taking certain drugs (including popular over-the-counter pain relievers) can increase this risk. Minor bleeding includes bleeding gums after toothbrushing or flossing and nosebleeds that take longer than usual to stop. Signs of more serious bleeding (which requires immediate medical care) include tea-colored, pink, or red urine; blood in the stool or black, tarry stools; or a sudden, severe headache.
