Medicines known as blood thinners are prescribed as long-term treatment to avoid initial or recurring blood clots that could cause serious complications. What does an ad in heavy rotation about the brand name blood thinner Eliquis get right and what else do you need to consider?

A 2021 study suggests that sildenafil (Viagra, Revatio), which is used to treat erectile dysfunction and pulmonary arterial hypertension, might also protect against Alzheimer's disease.

Almost 20% of people with hypertension may be taking medications that raise blood pressure, most often pain relievers such as ibuprofen (Advil) and naproxen (Aleve). Other classes, such as certain antidepressants, may also increase blood pressure.

There are many questions a patient should ask when a new medication is prescribed. Examples include why the medication is needed, what side effects to watch for, whether it might interfere with other drugs, how to take the drug, how long to take it, what to do for a missed dose, how to store it, how much it costs, whether there's a generic form, what signs indicate the drug is working, and how to get refills.

A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

The FDA recently moved to help make certain that women considering breast implants have a clear picture of what implants involve before moving ahead with surgery. The agency announced a series of changes in October 2021. These include new labeling requirements for breast implant manufacturers, a requirement that facilities provide patients with a checklist outlining potential risks and benefits related to breast implants, and updated screening recommendations to detect leaks in silicone breast implants.

Certain devices that use magnetic chargers may interfere with cardiac devices such as pacemakers. A doctor should advise people on which ones to avoid or to use caution when operating.

When a smart watch alert suggests that person's heart rate is below 40 beats per minute, it could be an error, especially if no symptoms are present. But it could signal a heart problem called bradycardia that has many possible causes.

Stimulant medications, which are usually prescribed to treat attention deficit disorder in children, are being prescribed increasingly to older adults. These drugs may cause a short-term spike in the risk of heart-related problems, including heart attacks, strokes, and arrhythmias. Dietary supplements that promise weight loss or better physical or mental performance may contain prohibited, unlisted, and potentially dangerous stimulants.

Nitrates are added to processed meats (such as bacon, ham, and deli meats) and are found naturally in leafy green vegetables (such as spinach and kale). But it's not clear how crucial these molecules are compared with other components of those foods, as dietary nitrate levels don't appear to affect heart disease risk. However, nitrate-based drugs are used to treat angina, a common symptom of coronary artery disease.
