Soil and water pollution from heavy metals, pesticides, and microplastics may affect a person's risk of cardiovascular disease. These pollutants can enter the body when people eat crops grown in dirty soil, drink water contaminated by dirty soil, or inhale soil dust. Lead, cadmium, and arsenic are among the most pressing concerns. Potentially helpful actions include testing one's drinking water, buying organic foods, and minimizing plastic use.

A bubble study is a test done in conjunction with an echocardiogram to check for the presence of a tiny opening between the heart's upper chambers called a patent foramen ovale. Such an opening could explain how an unexpected stroke happened.

Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

Being self-employed can offer advantages like flexibility and autonomy in a person's work life. Now, data from a long-term health study suggests that self-employment may provide another benefit for some women: improved health outcomes.

A trial from 2019 showed a medication dramatically reduced triglyceride levels in participants, but subsequent analysis found that the placebo used in the trial may have negatively affected those assigned to take it.

Taking an aggressive approach to lower high blood pressure with more medication can help many older adults reduce their risk for heart attacks, stroke, and heart failure. But they need to weigh the benefits with the potential side effects of extra medication.

Over the years, studies have produced conflicting results about the link between alcohol intake and heart health. Some studies suggest drinking alcohol protects against cardiovascular disease, including heart attack, heart failure, and stroke, while others imply the opposite. Now growing evidence says that not only won't alcohol lower a person's risk for cardiovascular disease, but consuming even moderate amounts may increase risk.

A big, hearty salad can provide the recommended daily dose of vegetables. Adding other filling ingredients such as starches and proteins turns a salad into a healthy, satisfying meal.

Sitting too much can boost stroke risk. But adding more movement—even low-effort activity such as doing household chores—may help lower that risk.
