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.

Leadless pacemakers, which are no bigger than a multivitamin pill, are far less prone to complications that traditional pacemakers, which have long leads (wires). These wires may become infected, dislodged, frayed, or broken. Scar tissue or blood clots can form around the leads, which may hinder blood flow and cause pain and swelling. Thanks to recent advances, most people who need pacemakers may now be candidates for leadless devices. However, doctors have less experience with what happens with leadless pacemakers over the long term-and they cost two to three times as much as a traditional pacemaker.

Drinking is linked to increased risks of high blood pressure. Alcohol elevates levels of the hormone renin, which narrows blood vessels and decreases urine output. The more often someone drinks, the more likely high blood pressure will result.

Older adults who consume ultra-processed foods as a substantial part of their diet have a higher risk of early death than those who eat less of these foods.

Carbohydrates include fiber, starches, and sugars. The healthiest sources include whole grains, legumes, vegetables, and fruits, which are rich in fiber as well as vitamins and minerals. Starches, the most commonly consumed form of carbohydrate, make up a large part of cereal grains such as rice, wheat, and corn; root vegetables such as potatoes and sweet potatoes; and vegetables like peas and winter squashes. Low-quality carbohydrate choices include sodas, candy, and sugary desserts.

Atrial fibrillation and supraventricular tachycardia are rapid, abnormal heart rhythms that originate in the upper part of the heart. But they tend to arise at different ages, and they require different treatments.

About one in five medications taken by older people is inappropriate. Many of these are heart drugs that are potentially harmful, have no clear benefit, or aren't as good as other options. These should be stopped or switched. One common example is low-dose aspirin, which is advised only for people who've had or are at high risk for a heart attack. Other drugs that may need to be stopped or replaced include beta blockers, warfarin, and older diabetes drugs.

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.
