Cardiac rehab appears to help people with atrial fibrillation

A 2025 analysis of randomized trials found that cardiac rehab—a personalized program of supervised exercise and healthy lifestyle coaching—can also help people with atrial fibrillation, an irregular heartbeat that can cause stroke and heart failure.

Heart-healthy habits appear to benefit the entire body

Habits that promote cardiovascular health are linked to benefits in nearly every organ system and improved function throughout the body, according to a 2025 review of 483 studies.

When do you really need an angioplasty and stenting?

Coronary artery disease, the most common form of heart disease, occurs when cholesterol-laden debris narrows the arteries that supply blood to the heart. It is treated with lifestyle changes and medications. However, sometimes people also need a procedure called angioplasty to open a blocked or narrowed artery to improve blood flow to the heart, along with insertion of a stent to hold it open. Most people need this if they experience a heart attack or unstable angina, when chest discomfort occurs repeatedly and unexpectedly, often at rest.

Just 7,000 daily steps reduces heart disease risk

A 2025 review found the people who walked 7,000 steps per day had a 25% lower of cardiovascular disease and a 47% lower risk of death from all causes compared to people who walked only 2,000 steps per day.

How do I make sense of my medication orders?

Hospital discharge instructions about medications can be complicated and confusing. Having a family member or friend along as a second set of ears during the discharge meeting can be helpful.

The heart attack and stroke emergency playbook

Everyone should learn what to do if a heart attack or stroke occurs, beyond calling 911. It helps to become familiar with heart attack and stroke symptoms, so they can be recognized. It’s also important to speak with one’s own doctor in advance, to find out if he or she advises taking an aspirin in one of those emergencies. Other precautions include keeping emergency contact and medication lists updated and handy, and talking about emergency plans with family and friends, especially one’s health care proxy.

The future of blood pressure monitoring: Cuffless devices

Many devices that measure blood pressure without an inflatable arm cuff are in development, including a wristband recently cleared by the FDA for over-the-counter sale. It relies on a light-based sensor to detect changes in the amount of blood flowing through the vessels of the inner wrist, a technique known as photoplethysmography. But the devices have to be periodically calibrated, and as yet, there are no standards to validate the accuracy of cuffless devices.

A cold drink may trigger an episode of atrial fibrillation

For some people with atrial fibrillation, cold drinks and foods can trigger a bout of the rapid, irregular heartbeat that characterizes the disorder. Avoiding those triggers nearly always prevents this phenomenon, dubbed “cold drink heart.”

Weight-loss strategies to protect your heart

Obesity is a common, chronic disease that can harm the heart. The powerful weight-loss medications known as GLP-1s, semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), are now recommended as first-line therapy for eligible people, according to the American College of Cardiology. People using these drugs should work with a dietitian or nutritionist who can help them create a personalized eating plan that ensures they’re getting enough nutrients while minimizing common side effects.

Infections, vaccines, and heart disease: What you need to know

Getting vaccinated against influenza (flu), COVID-19, and pneumonia is especially important for people who have cardiovascular disease. The coughing and congestion that commonly occur with respiratory infections can make breathing more difficult, and the potential drop in oxygen puts added stress on the heart. Serious infections sometimes trigger sepsis, which happens when the immune system is overwhelmed or goes into overdrive, causing symptoms such as a rapid heart rate, very fast breathing, and low blood pressure. These complications can lead to a heart attack.
