Having type 2 diabetes doubles a person's odds of heart disease, and this risk may be present as early as 30 years prior to the diabetes diagnosis, according to a 2024 study. The findings support the long-held observation of the shared underlying causes of diabetes and heart disease. These include factors that contribute to both conditions, especially the tendency to accumulate fat in the middle of the body, known as abdominal obesity. This problem tends to occur in tandem with high blood pressure, unhealthy lipid levels, and elevated blood sugar—a cluster of signs and symptoms called metabolic syndrome.

High levels of Lp(a)—a fatty particle similar to LDL cholesterol—may double or triple a person's risk of a heart attack. About one in five adults may have elevated levels, which also raises the risk of stroke and aortic stenosis. Unlike LDL, which rises with age and is influenced by diet and exercise, Lp(a) remains largely constant over a person's lifetime, so a one-time test suffices for screening. Lp(a) testing is becoming more common now that five promising new Lp(a) therapies are in development.

Social media sources may share misleading information about canola, soybean, and other seed oils. But these oils, which consist mostly of unsaturated fat, can be a good source of heart-healthy fat when combined with whole, fresh foods rather than in processed foods like crunchy, salty, or sweet snack foods. Consuming unsaturated fat in place of saturated fat (found mainly in animal-based foods) is linked to a lower risk of heart attack and death from heart disease.

After a heart attack or stent placement, people typically take a combination of aspirin and another antiplatelet drug. After one year, the new standard practice is to stop the aspirin, in contrast to the previous practice of stopping the other drug.

A 2024 study involving more than 72,000 healthy people ages 40 to 79 found that those whose sleep and wake times fluctuated most had a 26% higher risk of having a heart attack, stroke, or similar problem, compared with those whose sleep patterns fluctuated least.

Broken heart syndrome (officially known as takotsubo syndrome) causes symptoms similar to a heart attack. While intense emotional stress can trigger the condition, physical stressors such as surgery or severe illness are more common causes. Most cases occur in women, but proportion of cases recognized in men has risen in recent decades. Most people fully recover within weeks to months. But those who also have other serious health conditions may face a higher risk of dying within two months after being diagnosed with takotsubo syndrome.

In a 2024 study, researchers found that the heart rate variability of a dog and its owner mirror each other during interactions, which may reflect the strong emotional connection between humans and their dogs.

Each year, an estimated 700,000 Americans suffer from cardiac arrest, when the heart abruptly stops beating, causing the person to collapse and stop breathing. Immediately performing hands-on cardiopulmonary resuscitation (CPR) can more than double the odds of survival. Experts recommend that all adults should take an in-person CPR class at least once and have a refresher course every two to three years.
