Long touted as beneficial for heart health, high-density lipoprotein (HDL) is more complicated than experts once thought. Some forms of HDL grab cholesterol from the bloodstream and other tissues and transport it to the liver, where it's recycled or disposed, but other types are neutral or perform the opposite action. Most drugs that raise HDL don't seem to prevent heart disease, and very high HDL levels may even be linked to a higher risk.

Too much or too little potassium can harm the heart. Diet, medications, and kidney function can affect the body's potassium level. Dietary potassium helps keep blood pressure in a normal range, but most Americans don't consume enough of this mineral. However, people taking medications that raise potassium levels—which includes certain drugs to treat high blood pressure and heart failure—should avoid salt substitutes made with potassium chloride.

People with high triglyceride levels may be candidates for icosapent ethyl (Vascepa), a drug made from highly purified fish oil. It lowers triglycerides and, when taken with a statin, lowers the risk of heart attack, stroke, and death from cardiac causes.

Geriatricians offer health guidance and treatment to adults 65 and older. The specialty centers on health concerns increasingly common with age, including falls, hearing loss, incontinence, memory problems, and the need to juggle multiple conditions and medications. Among other goals, geriatricians aim to optimize drug dosages and prevent medication overlap or dangerous side effects. They also coordinate each patient's care with other specialists who help manage chronic conditions. Geriatrician visits are typically longer than those with general practitioners.

Around menopause, a decline in estrogen can trigger low-grade inflammation that leads to unexpected symptoms from head to toe. Symptoms can affect the digestive tract, skin, joints, eyes, ears, and heart, among other areas. A 2022 study found that estrogen loss can even fuel the jaw pain known as temporomandibular disorder. A year or longer can pass before many women connect symptoms with menopause. Women can take lifestyle measures to lower inflammation, such as eating more fruits and vegetables, avoiding processed foods, and exercising.

Following healthy habits like exercising, eating a proper diet, and being socially engaged can help people live a longer, healthier life. Still, the ultimate goal is not simply to live longer, but to enjoy life, which means placing more emphasis on quality of life. How life quality is defined can vary depending on people's goals, but it often revolves around three certain mindsets: having a sense of purpose, focusing on where one wants to devote time and energy, and enjoying the process and journey.

For some people, the effects of the influenza (flu) virus can lead to a heart attack or cardiac arrest (sudden death). These people typically have reduced blood flow to the heart due to atherosclerosis (narrowed arteries). Because the flu can cause blood oxygen levels to drop to dangerously low levels, it can further reduce the supply of oxygen to the heart, causing a heart attack or cardiac arrest. Fortunately, getting an annual flu shot is associated with reduced risks of a heart attack and related cardiac events.

Doctors around the world use standardized medical terms for a common frame of reference. Laypeople don't always know what that medical jargon means, which can lead to poor health outcomes. When a patient doesn't understand what a doctor is saying, it's important for the patient to ask for clarification. It may help to prepare a list of questions in advance and bring it to the medical appointment; bring a friend along who can take notes and ask questions; and repeat the doctor's advice before the end of the appointment, to make sure it's understood.

An estimated 3.2% of adults ages 50 or older have very low B₁₂ levels, and up to 20% may have borderline deficiency. Aging is often the cause. Other causes include taking heartburn medications; eating a diet that does not include animal products; weight loss surgery; or autoimmune diseases that attack the stomach lining or gastrointestinal tract. It’s a good idea for older adults to take a B₁₂ supplement of 2.8 micrograms daily to ward off B₁₂ deficiency. People who have very low levels of B₁₂ may need to take a much higher dose or get B₁₂ injections.

A 2022 study found that pregnant women who ate a diet rich in foods typical of a Mediterranean-style eating plan were significantly less likely to develop the potentially serious pregnancy complication pre-eclampsia.
