As many as 60% of heart attacks go unnoticed when they occur. So-called silent heart attacks occur for a variety of reasons, including differences in pain perception and people not recognizing symptoms or dismissing them. People may assume heart attack symptoms are limited to the chest, but nerves in the heart can send signals to the surrounding nerves, causing pain that radiates to the stomach, back, neck, arm, or jaw. Sometimes people assume their chest pain is caused by a respiratory infection or heartburn when they're actually having a heart attack.

About one in 500 people has hypertrophic cardiomyopathy (HCM), a condition that causes the walls of the heart to thicken and enlarge. It's often caused by genetic mutations and is the most common inherited form of heart disease. Contrary to popular belief, vigorous exercise appears to be safe for most people with HCM. For people with symptoms, several treatments are available, including mavacamten (Camzyos), a first-in-class medication that targets the underlying cause of HCM by inhibiting a protein that helps power heart muscle contractions.

Many tests and data can help people gauge their overall health, but when it comes to heart health, the most important are the "Big 3": blood pressure, cholesterol, and blood sugar. They can help predict cardiovascular disease risks, including heart disease, heart attack, and stroke. While standard guidelines from health organizations recommend what are considered healthy numbers for the Big 3, ideal numbers may differ depending on a person's health and other risk factors, and individuals should work with their doctor about which numbers to aim for.

In 2023, a small preliminary study found that single injection of a new RNA-based drug may lower blood pressure for up to six months.

Too much saturated fat tends to raise levels of harmful LDL cholesterol, but limited amounts are not a problem. Eating mostly whole or minimally processed foods can help achieve that goal.

Silent heart attacks often go unnoticed because they don't produce any symptoms or only mild symptoms that are mistaken for something else, such as heartburn or muscle pain. They are thought to make up from 20% to 60% of heart attacks and can raise risk of a future heart attack or related problem. Both women and men are at substantial risk. Making lifestyle changes and being proactive about managing risk factors for heart disease can help prevent future heart-related problems.

Periodontal disease, the leading cause of adult tooth loss, may increase the risk of diabetes, heart disease, and dementia.

A buildup of fat inside the liver, known as nonalcoholic fatty liver disease (NAFLD) affects about 25% of adults. This under-recognized condition is closely linked to obesity (especially excess weight around the middle of the body), type 2 diabetes, and cardiovascular disease. People with NAFLD can slow or even reverse the condition with the same lifestyle strategies that improve cardiovascular health: losing weight, adopting a healthy diet, and exercising regularly.
