Stroke killed 2,000 fewer Americans in 2008 (the last year with complete numbers) than it did in 2007, the Centers for Disease Control and Prevention (CDC) said yesterday in its latest annual Deaths report. That dropped stroke from the third leading cause of death in the United States to the fourth. Good news? Yes and […]

One of the things I like most about Thanksgiving is the laughter around the dinner table. The food is great, make no mistake. But it’s the sounds of happiness—the high peal, the good-natured guffaw, the snort-and-shaking-shoulders, and the deep belly laugh—that really make me give thanks. Laughter isn’t just a way to stay connected with […]

Taking an aspirin can protect you from heart attack, blood clots and more

First marketed by the Bayer Company in 1897, aspirin (acetylsalicylic acid) is one of our oldest modern medications — and its parent compound is much older still, since Hippocrates and the ancient Egyptians used willow bark, which contains salicylates, to treat fever and pain. Over the past 100 years, aspirin has made its way into nearly every medicine chest in America. Indeed, this old drug is still widely recommended to control fever, headaches, arthritis, and pain.

Although aspirin remains an excellent medication for fever and pain, other drugs can fill these roles equally well. But aspirin has a unique role that was not even suspected by its early advocates. In patients with coronary artery disease, aspirin prevents heart attacks.

Q. I avoid grapefruit juice because my doctor says it affects how my body handles the Lipitor I take for my cholesterol. Should I also stay away from pomelo?

A. The pomelo (also called shaddock, pumelo, pommelo, and Chinese grapefruit) is the largest citrus fruit, ranging from the size of a cantaloupe to that of a large watermelon. Botanists believe that crosses between pomelo and wild orange created grapefruit. Pomelo mixes the sweet taste of orange with the tang of lemon. Its lineage means that pomelo contains many of the same compounds as grapefruit.

Takotsubo cardiomyopathy, also called broken-heart syndrome, is a weakening of the left ventricle that is usually the result of severe stress. Its symptoms resemble those of a heart attack, and treatment is usually the same as that for heart failure.

Embryonic stem cell research continues to be a political and legal hot potato that stirs up a lot of emotion and argument. In the meantime, researchers are making some remarkable progress using an alternative stem cell approach called induced pluripotent stem cells, or iPSCs (sometimes that gets  shortened to iPS). An induced pluripotent stem cell is an adult cell, often a skin cell, […]

The advice to “keep it simple, stupid”—kiss, kiss—seems to apply to cardiopulmonary resuscitation (CPR). But with CPR, kiss-kiss means no mouth-to-mouth contact. A study published in tomorrow’s Journal of the American Medical Association (JAMA) adds to the evidence that the old way of doing CPR—alternating chest compressions with blows into the mouth—is needlessly complicated in most cases (there are exceptions, which we will get into below). Instead, this study and others (The New England […]

Rosiglitazone (Avandia) should be used only by people who can’t control their diabetes other ways, the FDA said today. Across the Atlantic, the European Medicines Agency ordered rosiglitazone off the market until its maker, GlaxoSmithKline, can supply “convincing data” that there exists a group of people with diabetes for whom the blood-sugar-lowering benefit of taking rosiglitazone […]

Prostate cancer drug treatments that block the activity of hormones have been associated with a higher risk of heart attack and heart disease. But a 2009 study suggests that these drugs may not cause cardiovascular problems after all.
