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.

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.

Shining a light on the diabetes–heart disease connection

Having type 2 diabetes doubles a person's odds of heart disease, and this risk may be present as early as 30 years prior to the diabetes diagnosis, according to a 2024 study. The findings support the long-held observation of the shared underlying causes of diabetes and heart disease. These include factors that contribute to both conditions, especially the tendency to accumulate fat in the middle of the body, known as abdominal obesity. This problem tends to occur in tandem with high blood pressure, unhealthy lipid levels, and elevated blood sugar-a cluster of signs and symptoms called metabolic syndrome.

Boosting share of protein from plants in diet may lower heart disease risk

A 2024 study found that people who follow a diet with a higher ratio of plant-based protein to animal-based protein may have a lower risk for cardiovascular disease and coronary artery disease compared with individuals who eat a lower plant-to-animal protein ratio.

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.

A heart disease trigger that lurks inside bone marrow

A condition caused by spontaneous genetic mutations in bone marrow cells, known as clonal hematopoiesis of indeterminate significance (CHIP), is linked to an increased risk of cardiovascular disease. Some of these mutations are clearly related to inflammation, a well-known contributor to the buildup of fatty plaque inside arteries. Experts hope that future research on CHIP will eventually lead to genetically directed therapies to address the condition.

Lipoprotein(a): An update on testing and treatment

High levels of Lp(a)-a fatty particle similar to LDL cholesterol-may double or triple a person's risk of a heart attack. About one in five adults may have elevated levels, which also raises the risk of stroke and aortic stenosis. Unlike LDL, which rises with age and is influenced by diet and exercise, Lp(a) remains largely constant over a person's lifetime, so a one-time test suffices for screening. Lp(a) testing is becoming more common now that five promising new Lp(a) therapies are in development.

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.

Even small amounts of extra exercise could lower blood pressure

A 2024 study suggested that even five minutes of additional vigorous daily exercise could lower blood pressure.
