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]

If you still have doubts about the perils of smoking, a new report in Circulation: Journal of the American Heart Association should clarify any suspicion. After looking at 13 major studies which evaluated the number of heart attacks after smoking bans were instituted in the US, Canada and Europe, researchers found that the total number of heart attacks dropped almost immediately – 17% within one year – and nearly 36% over a three-year period. This dramatic decline in heart attack rate is not only due to less smokers having heart attacks, but passive or secondhand smokers are spared as well. “This study adds to the already strong evidence that secondhand smoke causes heart attacks, and that passing 100 percent smoke-free laws in all workplaces and public places is something we can do to protect the public,” said study author James Lightwood, assistant adjunct professor in the department of clinical pharmacy at the University of California, San Francisco.

As the nation gears up for another July 4th holiday, those with respiratory diseases such as asthma, bronchitis and COPD need to be aware of potential disease flare ups due to soot and ozone propelled into the air by barbecues, fireworks, and the increased number of cars on roads. Exposure to high levels of ozone can cause coughing, wheezing, shortness of breath and even heart attacks in both healthy people and those with pulmonary disease. Therefore, be aware of your local pollution level and limit strenuous exercise (which can cause you to inhale more pollutants) during times of increased air pollution. Have a safe and happy fourth!

Physicians and researchers at Cedars-Sinai and Johns Hopkins hosipitals have embarked on an exciting study involving the use of stem cells to fix heart muscle that have been damaged during heart attacks. Heart-specific stem cells are harvested directly from the patient’s own heart and grown in a petri dish. The stem cells form clusters called “cardiospheres” that can even start to beat while in the dish. These cells are then injected back into the damaged heart of the patient from which they came. The researchers are hoping that these new cells will grow into healthy muscle to replace a damaged and scarred heart. This minimally-invasive procedure was completed in the first patient on Friday, June 26, 2009.

BMW and the German Federal Ministry of Education and Research are involved in a new project titled “SmartSenior – Intelligent services for senior citizens.” The goal of the project is the development of intelligent technology which recognizes and assists senior citizens in emergency road situations.  BMW is working on a safety system called Emergency Stop Assistant that will sense medical dangers, such as those associated with heart attacks, stroke and diabetes. Once an emergency is detect (through sensors that monitor vital signs disbursed throughout the car) the system will switch to an autonomous driving mode to safely stop the vehicle out of harm’s way.

New York University researchers published in the New England Journal of Medicine today that long term exposure to high levels of ozone, a main component of smog, is linked to an increased risk of death from respiratory diseases. Many studies have linked ozone to poor health, and others have shown that high-ozone days are linked to increased risk of acute health problems the next day, such as more asthma and heart attacks. However, this is the first study to demonstrate the effects of long term ozone exposure. In fact, the risk of dying from respiratory disease was more than 30 per cent higher in metropolitan areas with the highest ozone levels. During the 18-year study the city with the highest mean daily maximum ozone concentration was Riverside, California; the lowest ozone city was San Francisco. But even so, the average amount of ozone in San Francisco correlated with a 14 percent increase in death from respiratory diseases.

Smoking is a major risk factor for heart disease, including heart attacks. It is, therefore, no surprise that the CDC reported this week that hospitalizations for heart attacks in Pueblo, Colorado have sustained a 3-year decrease after the city implemented a law making public and work places smoke-free. Multiple studies have shown similar rapid and dramatic decreases within one year after the implementation of smoke-free laws. However, this was the first study to show that the benefits continue years after the initial drop.

The American Chemical Society reports new evidence that humans can make their own salicylic acid (SA), the compound largely responsible for aspirin’s effects on pain, fever, and inflammation. SA is a naturally occurring substance that can be obtained directly from eating fruits and vegetables. Researchers have previously shown that vegetarians have much higher levels of SA in their bodies (sometimes as high as in those who take low doses of aspirin). Now, the same research group claims that new evidence suggest that our bodies can actually manufacture SA from compounds we consume in our diet. Could SA be one of the chemicals responsible for the health benefits of a vegetarian diet? Numerous studies have shown that vegetarians seem to have a lower risk of obesity, coronary heart disease (which can cause heart attacks), high blood pressure, and diabetes.

Boston University researchers report that children of centenarians live longer than their counterparts, and with less risk of heart attacks, strokes, and diabetes. In a study published in the November issue of the Journal of the American Geriatrics Society, researchers found that offspring of centenarians had 78% lower risk of myocardial infarction (heart attack), an 83% lower risk of stroke, and an 86% lower risk of developing diabetes.

Regular aerobic exercise has been extensively studied and is known to have long-term cardiac benefits. However, did you know that listening to your favorite tune can dilate your blood vessels the same way exercise or drugs used to treat high blood pressure and cholesterol do? Researchers have shown that when people listen to music that makes them feel good (you pick the song) the effect of blood vessel dilation can last for almost an hour afterwords. Blood vessels that are able to react by dilating are termed as more “elastic.” More elastic vessels decrease the risk of atherosclerosis and blood clot formation that can lead to stroke and heart attacks.
