Hi Everyone,

We are excited to let you know about a new feature of RightHealth’s DailyDose blog.  Starting today, every Monday will be “Ask the Doctor” day.  In every Monday’s DailyDose post, I will respond to one of the questions posed by our readers.  If you have a question about a personal health issue or want to learn more about health topic that you find interesting, please email it to dailydose@righthealth.com.  Don’t worry, your identity will be kept confidential.

Please understand that we can’t answer all of your questions each week!  But we’ll do our best to select the questions which have the broadest interest among you.

So let’s get started!  This week’s question is from Mark V…

The cardiologist who recently examined President Obama, an admitted occasional smoker, told the Commander in Chief that although he received a clean bill of health, he’s still at risk for heart disease because he is a smoker in a high-stress job. Does smoking less frequently or just occasionally reduce the health risks for smokers?

Smoking accounts for over 400 thousand deaths annually in the United States, mostly in the form of lung cancer, stroke, and coronary heart disease. In fact, smoking increases every kind of cancer risk with 80% of lung cancers linked to smoking. It doesn’t matter if you smoke only one cigarette a day or one pack a day. The act of smoking will increase your risk of these diseases. We also know there is a clear link between second hand smoke and cardiovascular disease. Approximately 23 to 70 thousand premature deaths occur each year in the U.S. because of second hand smoke.

Does smoking less reduce health risks? The answer is yes. If you smoke three packs a day as opposed to one pack a day, you do have more of a risk for heart disease.  But it’s not until you quit smoking do you see some amazing results. Here’s what we know:

• At 20 minutes after quitting your blood pressure decreases and the body temperature of your hands and feet increase, due to improved circulation.
• At 24 hours you begin to see a decrease in heart attack risk.
• At 48 hours your senses of smell and taste improve and nerve endings actually begin to regrow!
• After 1 year your risk of coronary heart disease drops by 50%.
• After 5-15 years your stroke risk drops by 50%.
• After 10 years your risk of lung cancer drops by 50%.
• After 15 years your risk of coronary heart disease and death rate returns to the same level as those who never smoked.

A study from New York-Presbyterian Hospital in the current issue of Circulation: Cardiovascular Quality and Outcomes, a journal of the American Heart Association, shows that American women’s awareness of heart attack symptoms remain just as poor as it was over a decade ago. In fact, only 53% of women said they would call 9-1-1 if they were having symptoms of a heart attack. The majority of women were also not aware of these common symptoms – only 56%  cited chest pain and neck, shoulder and arm pain, 29% shortness of breath, 17% chest tightness, 15% nausea, and 7% fatigue as signs of heart attack. However, it should be noted that women do not necessarily experience these same classic symptoms as the majority of men. A significant number of women will experience symptoms such as shortness of breath, weakness, unusual fatigue, cold sweat, and dizziness as major symptoms during a heart attack. So, as heart disease continues to remain the top killer of women in the US, it is evident that continued education directed towards awareness of heart attacks in women is very much needed.

This past week new data suggested that some people taking the anti-obesity drug Meridia (sibutramine) are at greater risk of heart attacks and strokes than people taking a placebo. It also raised blood pressure and heart rate among users. What is interesting is how two large regulatory agencies responded to this data. The European Medicines Agency (EMEA) has already advised physicians and pharmacists to stop prescribing and dispensing the medication, while the U.S. FDA has urged pharmaceutical company Abbott Laboratories, the maker of Meridia, to place a stronger warning on the drug. The warning is to caution against the use of the drug by people who are already at increased risk of cardiovascular disease. Was the EMEA too hasty in its decision or is the FDA not forceful enough? Proponents of the drug agree that it shouldn’t be given to those with cardiovascular disease or diabetes, while critics are in favor of an overall ban. In the drug’s twelve years on the market it has been linked to more than 80 deaths, including 30 people under age 50. [via New York Times]

After tackling high-calorie fast foods and trans fats, the New York City Health Department is teaming up with other municipalities and companies to reduce the amount of salt in prepackaged and restaurant foods over the next five years. “Salt is a huge problem in our diets,” said Dr. Sonia Angell, director of the Cardiovascular Disease Prevention and Control Program at the New York City Department of Health and Mental Hygiene. “The majority of us consume too much salt, which increases blood pressure and puts us at risk for heart attack and stroke.” Most people need about 1,500 mg of salt per day. However, the average American adult consumes upwards of 3,500 mg, mostly from prepackaged and restaurant-served meals. The goal of the New York City initiative is to reduce sodium levels in prepared foods, so as to allow consumers to add salt if desired. Subway, one of the participating restaurants, has already committed to reducing salt in their sandwiches nationwide. “If salt is reduced gradually, we won’t notice a difference in our palate,” Angell said. “Our palate will adjust and we’ll enjoy foods as much as we do now.” [via CNN]

This week the British Medical Journal is warning physicians regarding high blood pressure (hypertension) treatment in people over 80 years of age. Despite limited evidence about treatment of hypertension in this age group, UK and US guidelines continue to recommend applying the same target blood pressures to people over 80 as to any other age group (the current target blood pressure for uncomplicated hypertension is 140/90). However, based on some new reviews of up-to-date data, there is evidence that mortality may likely be decreased by being more conservative with the number of drugs and the dosages of medications used in this group, in addition to allowing a higher target systolic blood pressure of 150. Trials are now needed to compare this conservative approach with the more aggressive treatment strategies currently in use. [via Medical News Today]

A new blood thinner not yet available in the U.S. is showing promise in its efficacy and safety. A study published in this week’s New England Journal of Medicine demonstrates that the drug, dabigatran etexilate, performed just as well as warfarin (also known as coumadin) in helping patients with potentially dangerous clots in their veins avoid a subsequent clot or death over the next six months. In previous studies dabigatran was shown to be effective in preventing blood clots in patients with acute coronary syndrome (an umbrella term for symptoms that may indicate a heart attack), and was superior to warfarin in preventing strokes among patients with atrial fibrillation, a type of heart arrhythmia. However, what sets dabigatran apart from warfarin is it’s easy of use. Since it doesn’t interact with food and has minimal interactions with other drugs it is very easy to manage how well one’s blood is being thinned out, unlike with warfarin where patients often visit an anticoagulation clinic once a week. Dabigatran is currently available in Canada and Europe. [via HealthDay]

Swedish researchers are reporting positive outcomes in a study examining the use of a device called RhinoChill, which cools the brains of heart attack patients by pumping coolant into the patient’s nose during CPR. In patients where resuscitation efforts began within 10 minutes of cardiac arrest researchers found that 59.1% of cooled patients and 29.4% of standard care patients survived to hospital discharge; 45.5% of cooled patients and 17.6% of standard care patients were neurologically intact at hospital discharge. The results also suggest that the earlier the cooling is started the better. When cooling efforts were delayed, there was no significant difference in survival when compared to those who did not receive nasal cooling. During a heart attack the heart is unable to properly pump blood to the brain (and other vital organs) which can lead to subsequent brain injury. [via Medline Plus]

The National Heart, Lung and Blood Institute (NHLBI) has published an update to their popular cookbook entitled “Keep The Beat.” It’s a collection of recipes that are limited in saturated fats, trans fats, cholesterol, and sodium, as well as being moderate in calories. The majority of the recipes were created in collaboration with Culinary Institute of America-trained chef and instructor David Kamen and a James Beard Foundation award-winning registered dietitian based on guidelines from NHLBI. For those with heart disease, or those who simply want to eat healthier, it’s often difficult to find nutritionally sound recipes that are delicious at the same time. Costing only a nominal $5 it may just be the healthiest pocket change you spent in a while. The book can be purchased at the NHLBI website. [via NIH News]

The Drug and Therapeutics Bulletin, a monthly review of pharmacotherapeutics in medicine published by the British Medical Journal, is recommending that physicians take a second look before prescribing daily low-dose aspirin to patients. A recent review of European data questions whether there is any benefit at all for those without a history of cardiovascular disease to be taking a daily aspirin, especially since long-term low-dose aspirin therapy almost doubles the likelihood of gastrointestinal bleeding (a potentially serious side effect). The journal authors support continued use of aspirin in those with known cardiovascular disease, such as diabetes, high blood pressure and heart attacks. But, in light of current evidence, is not recommending daily low-dose aspirin for prevention of cardiovascular disease. [via Drug and Therapeutics Bulletin]

Herbs and supplements are a largely unregulated market in the US. And now there’s new concern about an herbal supplement, aconite, which can be toxic to the heart. Aconite is a flowering plant that is commonly known as aconitum, monkshood and wolfsbane. It has also been called “herbal valium” because it can cause sensations of tingling and numbness. In higher doses it can slow down the heart and cause low blood pressure and heart rhythm abnormalities. Most homeopathic preparations containing aconite are likely safe since the aconite is appropriately diluted. However, consumers should be aware that herbal preparations may contain higher amounts and may cause dangerous side effects, especially if you have a heart condition. Speaking to your health care provider about any herbs and supplements you may be interested in taking is a good idea – it can serve to educate both you and your doctor! [via Medical News Today]
