Renal denervation, a nondrug treatment for uncontrolled high blood pressure, works by disrupting some of the nerves surrounding the renal arteries, which supply the kidneys. Two systems are FDA-approved for people whose blood pressure remains high despite lifestyle changes and medications. Renal denervation lowers systolic blood pressure by an average of 8 to 9 points—about the same as what people get with a single blood pressure drug. But the response varies widely; some people experience more dramatic drops, while others have no response.

People seeking motivation to be more active and connected to their community might consider signing up for a Turkey Trot, a race or "fun run" held on Thanksgiving morning. Most events are 5 kilometers (3.1 miles), and participants can walk all or part of the course. Many feature ways to support a local community charity.

People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.

The Brain Care Score is a quiz developed to help people identify proven, actionable steps to lower their risk of stroke, dementia, and depression. It includes four physical components (blood pressure, blood sugar, cholesterol, and body mass index); five lifestyle components (nutrition, alcohol intake, smoking, aerobic activities, and sleep); and three social-emotional components (stress management, social relationships, and meaning in life). Each response is given a point value, with the highest possible score totaling 21. Higher scores mean better brain care.

Heart attack symptoms can be severe or subtle. The underlying process that causes a heart attack can differ, and people may experience significant heart damage or little to none. Doctors diagnose a heart attack based on symptoms, a person's cardiovascular risk profile, electrocardiogram findings and the blood troponin level. Troponin is a protein released when heart damage occurs. Immediate and long-term treatment depend upon the type of heart attack and its impact on heart function.

A 2024 report suggests that rates of cardiovascular disease, diabetes, and colon cancer would fall substantially if people ate less red and processed meat.

A diagnosis of influenza (flu) was linked to a sixfold risk of heart attack over the following week, according to a 2024 report.

Air travel tips for people who have or are at risk for heart disease include bringing extra prescription medications in a carry-on bag and drinking water—but not alcohol—during the flight. When taking medications (especially blood pressure and anti-clotting drugs), people should try to schedule their doses based on their home time zone. On a long flight, walking a little every hour or so will help improve circulation in the legs; so can flexing the feet and circling the ankles. Doing so may reduce the chance of developing a blood clot, although the overall risk of such clots (known as deep-vein thrombosis) is quite low.

Leadless pacemakers, which are no bigger than a multivitamin pill, are far less prone to complications that traditional pacemakers, which have long leads (wires). These wires may become infected, dislodged, frayed, or broken. Scar tissue or blood clots can form around the leads, which may hinder blood flow and cause pain and swelling. Thanks to recent advances, most people who need pacemakers may now be candidates for leadless devices. However, doctors have less experience with what happens with leadless pacemakers over the long term—and they cost two to three times as much as a traditional pacemaker.
