When it comes to managing blood pressure, doctors tend to focus on lowering the top (systolic) number, but the bottom (diastolic) number also plays an essential role in heart health. Diastolic pressure is the pressure during the resting phase between heartbeats, and helps coronary vessels supply oxygen to the heart muscle. It’s important to keep both blood pressure numbers low per guidelines, but research suggests the diastolic number should not fall too low.

Traditional Southern cuisine features side dishes based on vegetables, beans, and whole grains that, when served together, can make a complete, meat-free meal that’s both filling and tasty.

A study of Black adults living in the Atlanta area suggests that feeling rooted in community and socializing with neighbors may strongly contribute to better cardiovascular health, which might lower risk for heart attacks and strokes.

Eating breakfast is a good opportunity to eat some of the nutrient-rich foods that help keep the heart in good shape. One option is whole-grain toast topped with avocado, which is rich in healthy fats and fiber. Another is oatmeal, known for its ability to lower cholesterol. Adding fruits and nuts provides additional nutrition. Eggs are another acceptable choice, ideally paired with vegetables instead of bacon, sausage, and white toast.

Consuming less sodium and more potassium may be linked to better heart health, according to a November 2021 study published in the New England Journal of Medicine. After controlling for other risk factors, the researchers found that for every extra 1,000 milligrams (mg) of sodium detected in the urine, there was an 18% increase in the risk of cardiovascular disease. For every extra 1,000 mg of potassium in the urine, there was an 18% decrease in risk.

People who follow a low-carbohydrate/high-fat diet for weight loss often eat high amounts of saturated fat. Even though saturated fat can contribute to cardiovascular disease, a 2021 study suggests that eating higher amounts might not be bad for heart health in the short term.

Older adults who eat fish several times a week may be less likely to develop early signs of cerebrovascular disease, a category that includes strokes, aneurysms, and related problems.

Being exposed to even low levels of certain toxic metals, including arsenic, cadmium, and titanium, may raise a person's risk for clogged arteries.

Anger or emotional upset may be linked to an increased risk of stroke within an hour of experiencing those negative emotions.

Air pollution is an often overlooked yet important contributor to cardiovascular disease. Tiny particles known as PM_2.5 travel deep into the lungs, where they irritate receptors and trigger nerves involved in the autonomic nervous system. This irritation also contributes to inflammation, which accelerates atherosclerosis. Climate change can worsen the damaging effects of air pollution in several ways, such as by promoting wildfires and dust storms, which creates more PM_2.5. To reduce pollution's harmful effects, people can check air quality information and use portable indoor air cleaners when pollution levels are elevated.
