A study published online Feb. 16, 2022, by the European Heart Journal suggests that the prevalence of statin intolerance is much lower than commonly cited. Instead of 50%, the study found that prevalence is 6% to 10%.

Full-fat dairy products such as yogurt and cheese can be part of a heart-healthy diet. Compared with nonfat or low-fat products, full-fat dairy products tend to be tastier and more filling. But because they contain more calories and saturated fat, it's best to limit full-fat dairy products to one serving a day and combine them with healthy foods, such as fruit, whole grains, and salads. Cheese is often eaten with less-healthy foods such as refined grains and meat, including pizza, burgers, mac and cheese, and Mexican food.

Heart attacks occur when a blocked coronary artery prevents blood flow to part of the heart. Cardiac arrest is caused by an electrical misfire that causes the heart to abruptly stop beating.

For most people, statins are still the best way to lower harmful LDL cholesterol. But two newer drugs may be promising additions or alternatives for those with stubbornly high LDL levels. Bempedoic acid, which lowers LDL by about 25%, works in a manner similar to statins but may help reduce muscle-related side effects seen with statins. Inclisiran interferes with a protein that's involved with regulating LDL production in the liver; it lowers LDL by about 50%.

Some people may also need to dial back their blood pressure medications if they experience side effects such as dizziness.

People who follow a low-carbohydrate/high-fat diet for weight loss often eat high amounts of saturated fat. Even though saturated fat can contribute to cardiovascular disease, a 2021 study suggests that eating higher amounts might not be bad for heart health in the short term.

Naturally occurring plant compounds called stanols can help reduce cholesterol. But they may not be found in large enough amounts in butter substitutes to reduce cholesterol levels in the body. The best way to lower is cholesterol is still by eating a plant-based diet with more fruits and vegetables and less processed foods, reducing consumption of saturated fat, and working to maintain a healthy weight.
