It is possible to experience a stroke without symptoms. Addressing cardiovascular risk factors can help lower the risk.

Some people with borderline high blood pressure have higher readings during winter, even high enough to need medicine to control it. In spring or summer, they might be able to reduce the dose or stop taking the medication. Losing excess weight and cutting back on salt also can help.

The most common type of heart failure in older adults is heart failure with preserved ejection fraction. This is caused by the heart's left ventricle not being able to relax, which means less blood enters the chamber, so less gets pumped out. Prevention and treatments continue to evolve, but include controlling blood pressure, addressing weight gain with exercise and diet, not smoking, and curbing alcohol intake.

The FDA called for the food industry to voluntarily cut the amount of sodium in processed, packed, and prepared foods. Those products provide about 70% of the sodium in the typical American diet.

Exposure to chemicals called phthalates, found in commonly used plastics, may be linked to a higher risk of dying from cardiovascular disease.

A draft guideline from a national panel of experts recommends that people without heart disease who are 60 and older should not take low-dose aspirin to prevent a heart attack or stroke.

For people over 60, aiming for a blood pressure target below 130/80 mm Hg may prevent more cardiovascular problems than aiming for the higher target suggested by some physicians. Some feared that the more intensive treatment required to reach the lower target might cause more adverse side effects (such as dizziness and falls) in older people. But side effects do not appear to differ among people taking intensive versus standard therapy.

For people with stable angina, which occurs in about two-thirds of people with heart disease, optimal medical therapy is almost always the best treatment. It includes all the medications a person needs to get cholesterol, blood pressure, and blood sugar into a healthy range. Certain medications, including beta blockers, calcium-channel blockers, and nitrates, also help relieve the discomfort of angina.

Reducing added sugar in sweetened beverages and packaged foods may help reduce obesity, diabetes, and heart disease in the United States, which could lead to substantial health care cost savings. Most of the added sugar in the typical American diet comes from sugary beverages, which add extra calories that have no nutritional advantages and may contribute to weight gain. Replacing sugar with artificial or non-nutritive sweeteners is one popular option, but it's not clear that eating such products offers any health advantages. A better option would be to substitute fresh, whole foods such as fruit for processed junk food and to drink sparkling water with a splash of juice instead of a soda.

In aortic stenosis, the heart's aortic valve narrows and can't open fully. In aortic regurgitation, the valve doesn't close properly. The cause may be present at birth (congenital) or acquired later in life, and the problems can occur alone or together.
