Osteoarthritis is the most common type of arthritis among older adults. Often called the “wear and tear” disease, osteoarthritis doesn’t occur because of overusing or stressing one’s joints. While there is no cure for osteoarthritis, people can lower their risk or better manage the condition by losing excess weight, strengthening the muscles surrounding joints, and using over-the-counter pain medication as needed.

Studies have shown a link between lower risks of cardiovascular disease, some cancers, and even dementia in people who consume higher amounts of olive oil. However, no definitive studies show extra-virgin olive oil has greater benefits than regular olive oil.

People with nonalcoholic fatty liver disease, which is fatty liver not caused by high alcohol intake, should refrain from most drinking and lose weight to avoid cirrhosis and lower their risk of liver cancer.

People who describe themselves as happy tend to have fewer health problems, a lower risk of depression, and longer lives. Research suggests that, on average, 50% of people’s general level of happiness is determined by genetics, with the rest dependent on the individual’s perception and specific circumstances. Some research suggests that people can adopt various strategies that can increase happiness, from forming stronger social bonds to investing in experiences to interacting more with outdoor green spaces.

Regular aerobic exercise such as walking and cycling may help people with resistant hypertension lower their blood pressure.

A Swedish study suggests that risk of a heart attack or stroke at least triples in the week following a COVID-19 diagnosis.

Diets rich in vitamin K, especially the kind found in green leafy vegetables and vegetable oils, are associated with a lower risk of cardiovascular disease.

So-called silent heart attacks (marked by unexplained weakness, fatigue, shortness of breath, or nausea) often go unrecognized. But they may be almost as concerning as regular heart attacks and have been linked to a higher risk of stroke. Some of this heightened stroke risk stems from shared risk factors, including high blood pressure, diabetes, and elevated cholesterol levels. But heart attacks can also damage the heart’s lower chambers. This may prevent the heart from contracting normally, which can lead to formation of a clot that then travels to the brain, causing a stroke.

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.

Post-traumatic stress disorder (PTSD) can be triggered by many harrowing events, including serious car accidents, violent personal trauma, and military combat. Over a lifetime, about 8% of adults develop PTSD, which is linked to an increased risk of heart disease. Many factors closely linked to heart disease—such as smoking, high blood pressure, and diabetes—are also common in people with PTSD, so untangling the true nature of the association has proven challenging. But repeated, long-term stress can increase blood pressure, heart rate, and inflammation, all of which can encourage clogged heart arteries. Ongoing research looking at the genetics and epidemiology of PTSD, cardiovascular disease, and their shared, related risks is under way.
