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.

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.

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.

Meatless burgers-which include plant-based meat alternatives like Beyond Burger and Impossible Burger and veggie burgers-are healthy replacements for traditional hamburgers. Those with the lowest amounts of saturated fat and sodium are the best options.

A 2025 randomized controlled trial found that GLP-1 receptor agonists, the blockbuster drugs approved to treat diabetes and obesity, boosted the walking ability of people with diabetes and peripheral artery disease (PAD) in the legs. The news is encouraging, since there are few effective treatments for PAD-reduced blood flow in the limbs that leads to pain with activity. However, it will take more evidence before doctors feel comfortable prescribing GLP-1s if a person only has PAD.

Ultraprocessed packaged foods and drinks contain thickeners, preservatives, and other additives to improve their taste, texture, appearance, and shelf life. But the high amounts of salt, sugar, and fat in these products are probably more concerning for a person's health. Foods like sugary drinks and processed meats are the worst culprits. Eating a diet focused on whole, plant-based foods automatically lowers processed food intake and provides heart-protecting nutrients such as fiber, vitamins, and minerals.

A 2025 suggests that an experimental drug called lorundrostat may be an effective add-on therapy for high blood pressure that has not responded to medication. The drug works by reducing aldosterone, a hormone that helps regulate blood pressure.

A 2025 study found that people who walk at an average or brisk pace (3 or more miles per hour) were less likely to develop abnormal heart rhythms than people who walk more slowly.

If a blood clot lodges in an artery or vein, it can choke off blood flow to the heart, brain, or lung. Often called blood thinners, anti-clotting drugs play a big role in treating heart disease. But they can cause minor (and sometimes serious) bleeding, ranging from nosebleeds to bleeding inside the brain. New solutions to balance clot prevention and excess bleeding are in the works, including low-dose drug combinations and new medications.

In a 2025 study of more than 420,000 participants followed for about 13 years, people who walked at a steady or brisk pace had up to a 43% lower risk for developing heart arrhythmias, compared with those who walked at a slow pace.
