What we eat plays an important role in health and quality of life - but is there a single best diet? One newer choice is the largely plant-based portfolio diet, which combines aspects of highly regarded eating patterns and focuses on foods proven to lower harmful blood lipids and enhance cardiovascular health.

In a 2024 study by Harvard researchers, people who reported feeling persistently lonely had a 56% higher risk of experiencing a stroke compared with people who did not report feelings of loneliness.

Mobile ECG devices are small, handheld devices that people can use to record a simple ECG at home. They are designed to detect heart rhythm disorders such as atrial fibrillation.

High levels of lipoprotein(a), or Lp(a)-a variant of LDL (bad) cholesterol- may triple the risk of a heart attack, even among healthy people with no other known risks for heart disease.

People with post-traumatic stress disorder (PTSD) are especially vulnerable to cardiovascular problems, including a 40% increased risk of heart attack. The amygdala, a brain structure involved in processing anxiety, fear, and stress, is overactive in people with PTSD. But these people also have decreased activity in the ventromedial prefrontal cortex, which is responsible for regulating emotions and dampening the fear response. This brain activity imbalance triggers chronic activation of the body's "fight-or-flight" response. The resulting physiological changes appear to underlie the development of atherosclerosis.

Older adults who received interpersonal exercise coaching (which included connecting with peers to learn and share information) improved their step counts and activity levels more than seniors who received intrapersonal coaching that was mostly self-focused, a 2024 study found. Finding an exercise partner (a spouse, friend, or neighbor) may help inspire people to exercise more. A group exercise class may provide the same benefit, in addition to providing structure, a trained instructor, and camaraderie.

Contrary to previous recommendations, people who think they are having a heart attack or stroke should not take an aspirin on their own. Their symptoms might be caused by a different problem that might be made worse by taking aspirin.

New research has found that Americans are now dying from heart failure at a higher rate than 25 years ago, making prevention more important than ever. The best strategy to lower one's risk from heart failure is to address its top underlying contributors: high blood pressure, abnormal blood lipid levels, and weight gain. Addressing these risk factors can also protect against developing coronary artery disease and diabetes, two of the main medical conditions that cause heart failure.
