Imaging tests such as chest CT scans and mammograms, which can detect calcium deposits in arteries, can provide information about a person's cardiovascular health. These so-called incidental findings-when a medical test discovers something unrelated to the original purpose of the test-have become increasingly common in recent years. With a chest CT, calcifications are grouped into four categories: none, mild, moderate, or severe. That's often enough for a cardiologist to make a solid decision about whether to maintain or intensify a person's drug treatment to prevent heart disease progression.

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.

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.

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."

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.

Few people get the recommended two fruits and three vegetables per day. Tips for helping people add more produce into their diets include starting small (making just one minor addition or substitution at a time and sticking with it for several weeks); choosing smarter snacks (like hummus and carrots or apples and peanut butter); sneaking pureed vegetables into pasta and other dishes; making smoothies and soups; and relying on frozen fruits and vegetables.

There are no medications to treat aortic stenosis (narrowing of the aortic valve), but several possibilities are currently being studied, including a class of drugs to treat diabetes and others that lower high lipoprotein(a) blood levels.

In a 2025 analysis involving about 200 million people, those who used cannabis had a 29% higher risk for sudden heart attacks or angina and twice the risk of premature death from cardiovascular disease, compared with people who didn't use cannabis.

Growing numbers of people have microvascular disease, which is caused by problems in the network of tiny blood vessels in the heart rather than blockages in the heart's major arteries. Evidence for this trend comes from large studies using diagnostic imaging tests coupled with heart disease registry data. Experts believe today's higher rates of obesity, diabetes, high blood pressure, and chronic kidney disease is changing how cardiovascular disease is manifested.

According to a 2025 study, people living near coastlines with high levels of marine microplastics had higher rates of heart disease than those living close to coastlines with less plastic pollution.
