Eating red meat has long been linked to a higher risk of heart disease. Breakdown products created by gut bacteria when people eat meat may contribute to this heightened risk, according to a 2022 study.

Catheter ablation destroys spots in the heart responsible for atrial fibrillation. Although traditionally used as a second-line treatment after medications fail, undergoing ablation earlier in the course of the disease may be a good option. The overall success rate for catheter ablation is around 75%. People sometimes undergo a second procedure if the first one isn't effective; this boosts the success rate to nearly 90%. Many factors, such as age, other health problems, and duration of afib can affect a person's outcome after catheter ablation.

The American Heart Association revamped its online tool, My Life Check, designed to help people prevent cardiovascular disease. Along with other changes, the AHA added healthy sleep duration to the list of seven other factors assessed by the tool. Those factors are maintaining a healthy weight, not smoking, being physically active, eating a healthy diet, and keeping blood pressure, blood sugar, and cholesterol at acceptable levels. Each factor (now known as Life's Essential 8) are scored on a scale of 1 to 100 and used to generate a composite cardiovascular health score.

Statins continue to be a first-line treatment for many people at risk of heart attacks and strokes. They help reduce cholesterol levels, reduce plaque build-up, and protect against plaque rupturing, and fight inflammation. Possible side effects are often mild, if they occur, and go away after a brief period. Otherwise, people can manage them by changing the dosage or switching to another type of statin, per their doctor's direction.

The American Heart Association added sleep to its list of factors for cardiovascular health. The others are a healthy diet; physical activity; low levels of nicotine exposure; and healthy levels of weight, cholesterol, blood sugar, and blood pressure.

After surgery unrelated to the heart, a diagnosis of atrial fibrillation (afib) may be more common than previously thought. These cases, which may constitute 13% of new afib diagnoses, appear to be undertreated.

Soil and water pollution from heavy metals, pesticides, and microplastics may affect a person's risk of cardiovascular disease. These pollutants can enter the body when people eat crops grown in dirty soil, drink water contaminated by dirty soil, or inhale soil dust. Lead, cadmium, and arsenic are among the most pressing concerns. Potentially helpful actions include testing one's drinking water, buying organic foods, and minimizing plastic use.

Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

Over the years, studies have produced conflicting results about the link between alcohol intake and heart health. Some studies suggest drinking alcohol protects against cardiovascular disease, including heart attack, heart failure, and stroke, while others imply the opposite. Now growing evidence says that not only won't alcohol lower a person's risk for cardiovascular disease, but consuming even moderate amounts may increase risk.
