Cold-water dips: Healthy or risky?

Swimming (or just dunking) in cold water is generally safe. But people with heart rhythm disorders should be cautious about this practice. The evidence for the health benefits for cold-water immersion (which allegedly include fat loss and reduced inflammation) is limited. Submerging the face in cold water triggers the diving reflex, which causes the heart to slow down and blood pressure to rise. This response, in addition to an adrenaline surge from cold water on the skin, may trigger an underlying arrhythmia.

Strength training and blood pressure

Most types of strength training, including weight lifting, are safe and beneficial for people who take medication for high blood pressure. But lifting very heavy weights (including boxes of books or heavy furniture) should be avoided.

High blood pressure? Treat the risk, not the number

People with a high risk for heart attacks and strokes might benefit from taking blood pressure–lowering medications, even if their blood pressure is in the normal or "high normal" range and they have no clear signs of cardiovascular disease.

Normal weight, but big belly? That raises heart disease risk

Excess fat in the belly brings a greater risk for developing heart disease, even if one has a normal body weight, according to an American Heart Association statement published online April 22, 2021, by Circulation.

Migraines linked to high blood pressure after menopause

Women with migraine headaches may be more likely to develop high blood pressure after menopause.

Reducing heart risks in the wake of breast cancer treatment

Hormone therapy is a highly successful breast cancer treatment for women, but it can elevate cardiovascular risk. Women can reduce those risks by being vigilant about their heart health and working closely with their doctors. Women who have taken or are taking these medications as part of breast cancer treatment should focus on adopting a healthy lifestyle, exercising regularly, and keeping close tabs on their blood pressure, cholesterol levels, and blood sugar levels.

Keep heart disease at bay with a salad a day?

Eating one cup of leafy green vegetables a day may help lower heart disease risk. Leafy greens are rich in nitrates, which the body converts to nitric oxide (a compound that helps reduce blood pressure).

Pregnancy problems may foretell future heart disease

Women who develop health problems such as high blood pressure or diabetes while pregnant face an increased risk of heart disease later in life.

Screening for atrial fibrillation: An update

Atrial fibrillation (afib), an often-silent heart rhythm disorder, increases the risk of stroke. Early detection may enable people to start taking anti-clotting drugs to prevent a stroke. Current afib screening methods include asking people about afib symptoms and taking an electrocardiogram during routine check-ups. Wearable devices such as smart watches and fitness trackers can detect afib, but they aren’t yet accurate enough to be used for widespread screening.

Why people faint: From common to very rare causes

All episodes of fainting results from insufficient blood flow to the brain. But there are many underlying causes for that diminished blood flow, ranging from common, usually harmless issues to rare, potentially serious problems. Common causes include vasovagal syncope and orthostatic hypotension; rare causes include carotid sinus hypersensitivity and rotational vertebral artery syndrome.
