Gum disease and heart health: Probing the link

Published January 1, 2022

About two-thirds of people over 65 have periodontal disease, which is linked to a higher risk of heart disease. Shared risk factors such as smoking and an unhealthy diet may explain the association, but bacteria and inflammation could be a common thread. The bacteria responsible for periodontal disease can travel to blood vessels throughout the body and have been found in the fatty debris (atherosclerosis) that clogs arteries located far from the mouth—and in blood clots from people who have experienced heart attacks.

What’s the best blood pressure target for older adults?

Published January 1, 2022

For people over 60, aiming for a blood pressure target below 130/80 mm Hg may prevent more cardiovascular problems than aiming for the higher target suggested by some physicians. Some feared that the more intensive treatment required to reach the lower target might cause more adverse side effects (such as dizziness and falls) in older people. But side effects do not appear to differ among people taking intensive versus standard therapy.

Salt substitute associated with lower rates of stroke, death

Published January 1, 2022

A large study published online Aug. 29, 2021, by The New England Journal of Medicine found that people who used a salt substitute on their food had a lower risk of stroke, heart attack, and early death, compared with people who used regular salt.

Saturated fat and low-carb diets: Still more to learn?

Published December 9, 2021

Low-carbohydrate diets have been popular for many years, but due to the high amounts of saturated fat, doctors and nutritionists worry about possible increased risk of cardiovascular disease. A study comparing three diets found that eating a high-fat diet did not necessarily raise heart risk, but the types and quantities of food make a difference.

Switching to a salt substitute may reduce stroke risk

Published December 1, 2021

Swapping regular table salt (sodium chloride) with a salt substitute containing some potassium chloride may lower the risk of strokes and related heart problems.

COVID-19 diagnosis raises risk of heart attack, stroke

Published November 1, 2021

A Swedish study suggests that risk of a heart attack or stroke at least triples in the week following a COVID-19 diagnosis.

Is extra-virgin olive oil extra healthy?

Published November 1, 2021

Studies have shown a link between lower risks of cardiovascular disease, some cancers, and even dementia in people who consume higher amounts of olive oil. However, no definitive studies show extra-virgin olive oil has greater benefits than regular olive oil.

The danger of a "silent" heart attack

Published November 1, 2021

So-called silent heart attacks (marked by unexplained weakness, fatigue, shortness of breath, or nausea) often go unrecognized. But they may be almost as concerning as regular heart attacks and have been linked to a higher risk of stroke. Some of this heightened stroke risk stems from shared risk factors, including high blood pressure, diabetes, and elevated cholesterol levels. But heart attacks can also damage the heart’s lower chambers. This may prevent the heart from contracting normally, which can lead to formation of a clot that then travels to the brain, causing a stroke.

Stroke prevention in atrial fibrillation: Beyond anti-clotting drugs

Published October 1, 2021

People with atrial fibrillation who develop or face a high risk of serious bleeding from anti-clotting drugs may be candidates for procedures that block or remove a part of the heart where dangerous blood clots form. About 90% of blood clots in the heart form in the left atrial appendage (LAA), a small pouch that protrudes from the top of the heart. Two procedures prevent clots from escaping from the LAA and causing a stroke. One delivers a device that blocks the opening of the LAA; the other removes most of the LAA during heart surgery done for another reason.

Exercise & Fitness

Exercise appears to lower atrial fibrillation and stroke risk

Published October 1, 2021

The link between exercise and atrial fibrillation (afib) and stroke prevention is now a little clearer, thanks to a Harvard study. It offers strong evidence that 150 minutes per week of moderate-to-vigorous physical activity is associated with a reduced risk for atrial fibrillation and stroke. Researchers aren’t surprised, since exercise helps the chambers of the heart contract and relax, while being sedentary increases afib and stroke risk. Other ways to ward off afib and stroke include treating sleep apnea, quitting smoking, and drinking only in moderation.
