Seafood selections that help your heart - and our planet

Choosing seafood that's lower on the food chain (such as herring, sardines, clams, and oysters) is beneficial for both cardiovascular health and the health of the environment. Finfish, crustaceans, mollusks, cephalopods, aquatic plants, and seaweed are all considered aquatic foods. Replacing terrestrial animal proteins such as beef, pork, and chicken (especially processed forms) with aquatic foods helps people eat less saturated fat and more omega-3 fatty acids. Also, producing aquatic foods generates far fewer greenhouse gases than producing terrestrial foods.

What you should know about recalls of cardiac devices

Implanted heart devices include pacemakers and implantable cardioverter defibrillators (ICDs), which monitor and correct abnormal heart rhythms. While very reliable, they are not perfect, and recalls of these devices affect thousands of people each year, according to a 2024 study. Testing the effectiveness and safety of cardiac devices is far more complicated than testing drugs. But efforts are under way to improve postmarket tracking of device complications by using electronic health records, Medicare databases, and registries developed in partnership with device manufacturers.

Soup up your diet

Winter soups containing beans, seasonal vegetables (such as squash, greens, and root vegetables), and whole grains are rich in heart-protecting nutrients. All the ingredients include lots of fiber, which helps lower cholesterol and is filling without adding too many calories. Homemade soups can be made with far less sodium (which raises blood pressure) than the amount found in many store-bought and restaurant soups.

Tracking your afib with a smart watch? Avoid this pitfall

People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

Need a push to learn CPR?

People can learn how to give chest compressions-a key aspect of cardiopulmonary resuscitation, or CPR-by watching a 90-second online video. CPR keeps blood flowing to the brain and vital organs during a cardiac arrest. There are various ways to practice chest compressions on a mannequin, including at an in-person class or at one of 30 kiosks (including six at major airports) located nationwide.

Device of the month: Smart ring

Smart rings can do many of the same things a smart watch can, including heart rate monitoring, blood oxygen level measurement, and activity and sleep tracking.

What's the right blood pressure?

U.S. guidelines define normal blood pressure as less than 120/80 millimeters of mercury (mm Hg). Studies have shown that the lower a person's blood pressure, the greater the heart health benefits. However, the "best" blood pressure number for someone depends on several factors, such as the person's health condition, lifestyle, family history, and personal goals. Depending on an individual's situation, a higher-than-normal number may be adequate.

Drops in air pollution linked to fewer heart disease hospitalizations

A 2024 study found that when air pollution levels decreased during a five-year period in Italy, so did hospitalizations for heart-related emergencies. The results suggest that reducing air pollution could lower the prevalence of heart disease.

Heart and soul: Spirituality in cardiovascular care

Most hospitals have chaplains who can provide emotional and spiritual support to patients and their families during challenging medical situations, such as impending heart surgery, a worsening bout of heart failure, or cardiac arrest. Spiritual care, which has been linked to improved health outcomes, encompasses but does not necessarily include formal religious practices. It aims to help people explore sources of comfort and hope while coping with the challenge of a diagnosis.

The latest thinking on inherited high cholesterol

About 5% of Americans have low-density lipoprotein (LDL) values of 190 mg/dL or higher. Their risk of heart disease is five times higher than people with near-optimal values (less than 130 mg/dL). Some have familial hypercholesterolemia, a genetic condition that can lead to LDL values up to 350 mg/dL (or even higher in some cases). Known as FH, it's a common cause of early heart attacks.
