Air travel tips for people who have or are at risk for heart disease include bringing extra prescription medications in a carry-on bag and drinking water-but not alcohol-during the flight. When taking medications (especially blood pressure and anti-clotting drugs), people should try to schedule their doses based on their home time zone. On a long flight, walking a little every hour or so will help improve circulation in the legs; so can flexing the feet and circling the ankles. Doing so may reduce the chance of developing a blood clot, although the overall risk of such clots (known as deep-vein thrombosis) is quite low.

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.

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.

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.

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.

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.

People with hypertension who monitor their blood pressure at home may be able to successfully self-titrate their blood pressure medications, a 2024 study suggests. First, they need to know their target blood pressure. Readings that remain above goal requires consultation with their doctor to create a plan for better BP control, such as specific steps for medication self-titration.

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.
