The FDA has approved a new drug called rilonacept (Arcalyst) to specifically treat recurrent pericarditis, a painful inflammation of the fluid-filled sac that surrounds the heart.
Women who develop health problems such as high blood pressure or diabetes while pregnant face an increased risk of heart disease later in life.
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.
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.
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.
A buildup of fat inside the liver, known as nonalcoholic fatty liver disease (NAFLD) affects about 25% of adults. This under-recognized condition is closely linked to obesity (especially excess weight around the middle of the body), type 2 diabetes, and cardiovascular disease. People with NAFLD can slow or even reverse the condition with the same lifestyle strategies that improve cardiovascular health: losing weight, adopting a healthy diet, and exercising regularly.
Melons have a high water content and are fairly low in calories, making them a good choice for people watching their weight. Watermelon contains lycopene and citrulline, two nutrients thought to benefit heart health.
Enhancing food with different flavors from spices, herbs, aromatic roots, citrus juice and zest, and vinegars can help people eat less sodium, a main component of salt. Fresh herbs such as basil, cilantro, and mint can deliver flavor, fragrance, and color to foods; so can spice blends such as garam masala, za’atar, and Chinese five-spice blend. Other flavor-boosting, salt-free strategies include choosing the freshest possible foods and using appropriate cooking techniques. Reducing dietary sodium helps lower blood pressure, which reduces cardiovascular disease risk.
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.
Adopting healthier lifestyle habits doesn’t happen at once, but is a process that happens in stages. Setbacks along the way are normal, but they provide opportunities for growth and learning.
