Living with a dog may help protect against heart disease and help people live longer. Potential perks of dog ownership include lower blood pressure, a lower resting heart rate, and possible small improvements in cholesterol levels, perhaps because dog owners are less sedentary than non-owners. But dogs may also provide emotional and social benefits, such as reducing loneliness and anxiety, encouraging people to interact with neighbors, and fostering stronger ties to the community.

The blood vessels that supply the heart may narrow with age, known as coronary artery disease. But people have misconceptions about this condition, which is responsible for the heart attacks that strike somewhere in this country roughly every 40 seconds. For example, people don’t usually experience angina (the classic symptom of coronary artery disease) until an artery is 70% to 90% blocked. Angioplasty plus a stent to reopen a blocked coronary artery can be lifesaving when done during a heart attack. For people with stable angina, a stent can relieve symptoms but has not been proved to prevent a future heart attack or extend a person’s life.

Golf is a low-impact sport with several features that make it a good exercise for people who have or are at risk for heart disease. Playing 18 holes of golf without riding in a cart involves walking four to five miles, which easily meets the recommended daily step count of 10,000 steps. It also provides a chance to socialize with friends and to spend time in a relaxing natural environment, which may help lower stress.

At-home genetic tests such as 23andMe and Ancestry Health are unlikely to help predict a person’s odds of heart disease. The results reveal only limited information about a person’s risk for abnormally high cholesterol (a condition known as familial hypercholesterolemia) or harmful blood clots (known as hereditary thrombophilia). Most cases of coronary artery disease, the most common form of heart disease, are polygenic, meaning they result from changes in multiple genes.

Although it’s classified as a seed, quinoa is usually eaten like a whole grain, as a side dish or added to salads and soups. Quinoa is rich in high-quality protein, making it a good choice for people trying to eat a more heart-friendly, plant-based diet.

A vegetarian diet may help lower a person’s risk of stroke. Diets high in plant-based foods are rich in fiber and antioxidants, which help protect against cardiovascular disease.

For people with coronary artery disease or peripheral artery disease who also have diabetes, a combination of clot-preventing drugs helps lower their risk of heart attack or stroke.

The dietary supplement CoQ₁₀ does not seem to help prevent muscle pain associated with taking cholesterol-lowering statins.

Research has shown that feelings of general anxiety, nervousness, and fear tend to rise with age. This can lead to increased isolation and less exercise, and may progress to an anxiety disorder. Strategies to help manage and overcome increased feelings of fear include seeing a therapist, practicing mindfulness, consulting with a financial expert, and hiring a personal trainer.

A well-hydrated person’s urine color is often pale yellow. However, certain colors, especially red or brown urine, can signal problems that should be checked out by a doctor.
