Understanding the different types of "brain attack"

Strokes fall into two main categories: ischemic (which result from a blockage inside one of the brain's arteries and account for 87% of all strokes) and hemorrhagic (also known as bleeding strokes, usually from a ruptured blood vessel). Three main types of ischemic strokes are those that result from atherosclerosis in a large artery supplying the brain (large-artery atherothrombotic strokes); those caused by clots in the heart that travel to the brain (cardioembolic strokes); and those in the brain's smallest vessels (small-vessel strokes).

The cancer–heart disease connection

Cancer survivors are more likely to die of heart disease than from cancer-related complications. One reason is that certain cancer treatments can cause cardiovascular complications. But the two diseases share many root causes, including tobacco use and obesity, as well as diabetes and high cholesterol. Growing evidence suggests that people with heart disease may be more likely to develop cancer.

Varicose veins: More than a cosmetic concern

Varicose veins are not just unsightly and uncomfortable; they can also be harbingers of more serious conditions, including deep-vein blood clots and venous ulcers. Ablation therapies to eradicate varicose veins can lower these risks. People can also try simple strategies to prevent and improve varicose veins, including doing exercises that work their calf muscles, elevating their legs, and wearing compression stockings.

New thinking on important blood tests

The approach to certain blood tests appears to be shifting. Doctors might stop ordering routine vitamin D screenings for healthy people younger than 75; they might order a one-time combination of lipoprotein(a), C-reactive protein, and LDL (bad) cholesterol tests as a way to predict future heart problems; and they might rely less on standard ranges designated as "normal" in a complete blood count (CBC) test, and instead focus more on comparing someone's latest CBC results to previous CBC tests.

The heartfelt effects of kindness

Engaging in prosocial, altruistic behavior that benefits other people-such as doing volunteer work, giving money to charity, or performing small acts of kindness-may be beneficial to cardiovascular health. Possible mechanisms include reductions in stress and blood pressure. Volunteering has also been associated with improvements in heart-related risks, including increased step counts and less depression.

Coping with heart disease and arthritis together

For people who have both heart disease and arthritis, two of the main treatments-exercise and medications-require careful planning and attention. Joint pain makes certain types of exercise difficult, and commonly used drugs for both conditions can have potentially serious interactions.

Fasting before lipid test usually unnecessary

Most people don't need to fast before a lipid test because the difference between LDL cholesterol values when fasting or not fasting is very small. But people who have had high triglyceride levels should fast prior to the test.

Brief bursts of vigorous activity linked to lower heart risks

Briefly running or climbing stairs are examples of vigorous intermittent lifestyle physical activity (VILPA). Just a few minutes of VILPA per day was linked to a lower risk of heart-related problems among women who don't exercise, a 2024 study found.

No cognitive effects seen after years of very low LDL cholesterol

Having an extremely low LDL level from aggressive cholesterol-lowering therapy was not associated with cognitive impairment, according to a 2024 study.

Daily dose of dark chocolate linked to lower diabetes risk

In a 2024 study, people with a habit of eating dark chocolate-about an ounce a day-were less likely to develop diabetes compared to those who didn't consume it.
