There are few medical conditions that people fear more than a stroke. We know that blood pressure control and lowering cholesterol levels reduces stroke risk. Now, thanks to a huge analysis from Italy published in the Journal of the American College of Cardiology, we know that higher dietary consumption of potassium is associated with lower rates of stroke and could also reduce the risk of coronary heart disease and total cardiovascular disease, too. What is even more remarkable is that the results apply to all parts of society and not just to specific “at-risk” subgroups.
Most doctors aren’t even aware of how important it is to eat potassium-rich foods. And what are these foods that have potassium? Surprise: It’s fruits and vegetables like bananas, tomatoes, oranges, apricots, most legumes, spinach, winter squash, avocado, kiwi, and cantaloupe. Actually, almost all fruits and veggies have moderate to high potassium content.
The researchers looked a number of well-done studies that included 247, 510 participants over age 30 and found that those patients with the higher potassium intake reduced their stroke risk by 21 percent. The Italian doctors say the protective effect of potassium against stroke is in part due to its blood pressure lowering effects and also due to other properties of the potassium mineral, such as the inhibition of free radical formation.
I’ve written before about the DASH diet, which also found that reduction of sodium and addition of fruits and vegetables to the diet is an effective way to control blood pressure. The DASH diet is high in potassium.
Think about it: Did you have five servings of fruits and vegetables today? Numerous studies have shown their life-prolonging benefits. This new study just adds to what we already know. I challenge all readers to keep a diet count and make sure you are eating five fruit and vegetable servings a day — every day — to help reduce your risk of stroke, cancer, and heart attack.
News that tennis star Serena Williams was treated for a blood clot in her lungs is shining the spotlight on a frightfully overlooked condition that can affect anyone — even a trained athlete who stays fit for a living.
Williams had a pulmonary embolism. That’s doctor speak for a blood clot that originally formed in the legs or elsewhere in the body but that eventually broke away, traveled through the bloodstream, and got stuck in a major artery feeding the lungs. (To read more about pulmonary embolism, check out this article from the Harvard Heart Letter.) Pulmonary embolism is serious trouble because it can prevent the lungs from oxygenating blood — about one in 12 people who have one die from it.
“No one is immune from pulmonary embolism, not even super athletes,” says Dr. Samuel Z. Goldhaber, professor of medicine at Harvard Medical School and one of the country’s leading experts in this clotting disorder.
Pulmonary embolism tends to happen among people who have recently had surgery, been injured, or been confined to bed rest for some time. It can also strike after long-haul flights.
Signs of a PE
How do you know if you’re experiencing a pulmonary embolism? The most common symptoms include shortness of breath when you aren’t exerting yourself, along with chest pain and coughing up blood. If you experience any of these symptoms, see a doctor immediately. Other worrisome signs include:
Excessive sweating
Clammy or bluish skin
Light-headedness
Fast or irregular heartbeat
The tennis star’s pulmonary embolism could have been the result of the perfect storm. After having a cast removed from a foot she cut at Wimbledon, Williams flew from New York to Los Angeles. It was in LA, after an appearance at the Oscars ceremony on Sunday, that she underwent emergency treatment at Cedars Sinai Hospital for a blood clot in her lungs.
A call to action by the U.S. Surgeon General says that pulmonary embolism and a related condition — deep-vein thrombosis — affect an estimated 350,000 to 600,000 Americans each year. Together, they account for somewhere between 100,000 and 180,000 deaths each year.
Having a baby can be a beautiful thing until something goes wrong. The tragedy is that many high-risk conditions can be managed appropriately if the patient is cooperative and the healthcare provider is competent and well trained. Unfortunately, almost 600 pregnant women die in the U.S. each year from complications and the most common complication is significant blood loss after birth or postpartum hemorrhage (PPH).
PPH occurs when there is a blood loss of 500 cc or greater for a vaginal delivery and 1,000 cc after a cesarean section (C-section). Or, if you were admitted with a hemoglobin of 12 and it drops by ten points to 11, there should be a high index of suspicion for PPH as well. Therefore, if you feel lightheaded or dizzy, have palpitations or an increased heart rate after delivering a baby, inform the hospital staff immediately.
The most common cause of PPH is uterine atony or lack of contractions after the baby is delivered. Any pregnant condition that stretches the uterus significantly — such as having twins or a higher gestation, excess amniotic fluid (aka polyhydramnios), a prolonged induction of labor (greater than 24 hours) — increases the risk of PPH. Retained products of conception, such as the placenta, also places the patient at risk for developing PPH.
Other risk factors for PPH include:
Women with a known placenta previa
African-American women
Hypertension or preeclampsia
Mothers with infants weighing greater than 8.8 pounds (or 4,000 grams)
Mothers with greater than seven children
Women with a history of hemophilia
If you have any of the risk factors listed above, please be proactive and discuss the possibility of a PPH with your healthcare provider. Read more »
The film “The King’s Speech” won the Academy Award for Best Picture [on Sunday night.] The movie has come in for some criticism for its depiction of the political machinations surrounding the abdication of Edward VIII and Britain’s appeasement of Hitler. The British-born writer Christopher Hitchens, unsparing and deliciously eloquent as always, puts the politics of George VI in a far less favorable light than the movie does.
But “The King’s Speech” has won almost universal praise for its portrayal of the reluctant monarch’s stuttering, a speech pattern that includes involuntary repetition of sounds and syllables and “speech blocks” that cause prolonged pauses. Many young children who stutter grow out of the problem, but perhaps as many as one in every 100 adults are affected by the condition, 80 percent of whom are men. Stuttering clusters in families, so researchers have been searching for inherited genes that might cause the condition. Last year, in The New England Journal of Medicine, NIH researchers reported some success with results showing an association between three mutated genes and stuttering, although those mutations are probably responsible for a very small minority of cases.
It’s been said that “The King’s Speech” will do for stuttering what “Rain Man” did for autism: Plant a sympathetic view of a disability in the public consciousness. One danger of such a quick infusion of awareness, however, is that it can harden into a fixed, if largely favorable, stereotype. We are finding out — or are being reminded — about all the famous people who have stuttered (many of them writers). First-person accounts are popping up all over the place because of the film. The best I’ve come across is by Philip French, a British film critic, who describes vividly what it was like to listen to the radio broadcasts of the real King George VI, wondering if he would make it to the end “like a drunken waiter crossing a polished floor bearing a tray laden with wine glasses.” Read more »
Want to try to avoid a visit to the doctor for that cough or cold? Why not go to the pharmacy to get an over-the-counter (OTC) medicine? In this video from local TV news, I talk about the good and bad of OTC cough and cold meds. Will that medicine from the pharmacy actually help you get better faster?
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
