A bold initiative called Million Hearts aims to prevent one million heart attacks and strokes from happening over the next five years. As explained in the Harvard Heart Letter, the initiative is spearheaded by the federal Centers for Disease Control and Prevention (CDC) and the Centers for Medicare and Medicaid Services. Its main focus is to encourage more widespread and appropriate use of simple, effective, and inexpensive heart-protecting actions, dubbed the ABCS. These include taking daily low-dose Aspirin, if prescribed; managing Blood pressure and Cholesterol levels; quitting Smoking. The Harvard Heart Letter adds D for Diet and E for Exercise.

“Limit salt” has been a key part of dietary advice for decades. Once aimed at individuals, the FDA is hoping to persuade food companies to cut back on salt added to prepared foods. That’s probably a good idea, since the average American gets more salt—and thus sodium—than needed, most of it from prepared foods. But the question of how low we should go with sodium hasn’t been answered. Two studies suggest that getting too little sodium could pose problems, just as eating too much does. Trials to determine the safest range for sodium aren’t in the offing. What to do in the interim? Aiming for the recommended target of 2,300 milligrams per day from all sources is probably good for most people.
In most people, blood pressure begins to rise just before getting out of bed in the morning, and reaches its peak around mid-day. It falls during sleep, reaching its lowest point of day between midnight and 3:00 or 4:00 am. This drop is sometimes called “dipping.” But people with high blood pressure often have little or no decrease in their blood pressure at night. One possible reason for this is blood pressure medicines taken around breakfast time have worn off. That oft-quoted passage doesn’t A new study suggests that taking blood pressure drugs at night might improve blood pressure and prevent more heart attacks and strokes than taking the same medications during the day.
Heart disease, stroke, diabetes, asthma, osteoporosis and other common chronic diseases are often blamed on genes, pollution, or the wear and tear caused by personal choices like a poor diet, smoking, or too little exercise. An intriguing hypothesis is that these and other conditions stem from a developing baby’s environment, mainly the womb and the placenta. During the first thousand days of development, from conception to age 2, the body’s tissues, organs, and systems are exquisitely sensitive to conditions in their environment during various windows of time. A lack of nutrients or an overabundance of them during these windows, so the thinking goes, programs a child’s development and sets the stage for health or disease.
The combination of brutal heat and humidity can be downright dangerous to people with heart disease and other chronic conditions. They may have trouble getting rid of extra body heat, or the process may strain the already–overworked heart and arteries. Taking it easy, finding air conditioning, and drinking plenty of water (not sugary soda or fruit juice or caffeinated beverages) can help beat the heat. It’s also important to be aware of the warning signs of heat illness—nausea or vomiting, unusual fatigue, headache, disorientation or confusion, or muscle twitches—and call for help right away.
Millions of people take nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin and others), naproxen (Aleve, Naprosyn, and others), and celecoxib (Celebrex) to relieve pain and inflammation. During the last few years, researchers have raised concerns that taking these drugs often may be hard on the heart as well. The latest study, published in the July 2011 issue of the American Journal of Medicine, suggests that regular use of NSAIDs poses a special problem for people who already have heart disease, boosting their chances of having a heart attack or stroke. This research doesn’t mean that people with high blood pressure and heart disease should stop taking NSAIDs, especially if they are used to ease pain from a chronic condition like arthritis. But it may make sense to try an alternative first.
A new study from Europe published in the May 4 Journal of the American Medical Association shows that taking in less salt may increase the risk of heart disease and has little effect on the development of high blood pressure. The findings contradict results of many other studies showing that less salt prevents heart disease. Flaws in the new study, from the young age of the participants to the small number of heart attacks, strokes, and other cardiovascular problems that occurred over the course of the study, suggest that it is not a game changer. If you are leery about the low-salt message for whatever reason, there are other ways to keep your blood pressure in check, like more exercise, weight loss, and following a diet like the DASH diet.
A panel discussion at Harvard School of Public Health called “Boosting Vitamin D: Not Enough or Too Much?” highlights the current controversy over the once-overlooked sunshine vitamin. A panel of experts assembled by the Institute of Medicine recommends a daily dose of 600 IU per day for everyone from ages 1 to 70 and 800 IU for those over 70. Other experts think the IOM recommendation is too low. One way to get vitamin D is to spend a few minutes a day outside in the sun, but that’s a hot-button issue because sun exposure is a cause of skin cancer.
A large new study links drinking sugar-sweetened sodas and juices with higher blood pressure and extra pounds. The results are in line with earlier studies, and with some clinical trials, showing that daily consumption of sugar-sweetened beverages isn’t so good for the body.
Health problems, or treatments for them, sometimes thwart sexual desire and sexual function. There may not be a quick fix for health-related sexual problems, but there are things you can do to enjoy your love life while taking care of the rest of your health.
