How Can We Prevent Heart Disease?
Dr. Valentin Fuster discusses the rise of cardiovascular disease in the developing world, where the percentage of people who die from heart disease has reached the same levels as in the industrialized countries.
In the developed world it is common medical practice to prescribe 3 drugs to treat coronary related health problems, statins, ACE-inhibitors and aspirin. The average cost per day for this treatment is $2 to $2.50 a day. While this is an acceptable cost in the industrialized world it is unaffordable to the majority of people in poorer countries, where cardiac disease has become a leading killer. Also, the age of death for these cardiac patients is at a younger age than in industrialized nations due to lack of treatment.

The Future of Treating Cardiovascular Disease
Dr. Valentin Fuster discusses the future of treating cardiovascular disease. Dr. Fuster describes the rising worldwide spread of heart disease, as populations in the developing world are now demonstrating rates of heart disease seen previously only in industrialized countries. Simply stated the United States and the rest of the world simply cannot afford to treat cardiovascular related diseases. While we can provide remarkable cures, from stents to heart transplants, it is simply too expensive. Even in America, we will not be able to provide treatment.

Are We Winning the Battle Against Heart Disease?
Dr. Valentin Fuster discusses the paradox of people living longer despite the dramatic increase in the incidence of cardiac disease in the general population. While breakthrough treatments have helped increase the life-span of the population by two years every decade in the last half of the 20th century, the increase in obesity has also increased the number cardiac patients requiring treatment.

The Body's Three Natural Defenses Against Cardiovascular Disease
Dr. Valentin Fuster discusses the body's three natural defense mechanism against cardiovascular disease. First, he describes progenitor endothelial cells produced by the bone marrow help protect coronary artery disease and the prospects of how pharmacologically we may help support the body in this defense mechanism. Secondly, he describes how blood gradient concentration with the help of statins extracts cholesterol from the coronary arteries. Finally, he describes how HDL or good cholesterol helps keep the coronary arteries clear of LDL or bad cholesterol.

Restless Legs Linked to Heart Disease and Stroke
A study published in the latest issue of Neurology found that people with restless leg syndrome (RLS) have double the risk of heart disease and stroke. The study included nearly 3,500 community based participants of average age 68 years from the Sleep Heart Health Study. The researchers used information provided by participants through detailed questionnaires to establish who had RLS and who had received a diagnosis for symptoms of angina, myocardial infarction, stroke or heart failure to help determine the presence of coronary artery disease and cardiovascular disease including reports of stroke or heart failure.

Risk of Heart Attacks and Stroke Doubled by Flu
A recent study from the London School of Hygiene has found that winter infections such as influenza can double the risk of heart attacks and strokes. The effects were found to be independent of age or gender. Victims are twice as likely to be affected during the week following a respiratory infection. The extensive study included two million patients.. Scientists believe that infections such as the flu dislodge fatty deposits and/or blood clots that accumulate in the arteries, leaving them free to move around the body and potentially clog the circulation of the brain or heart where they may block blood flow. There are also cases where viral infection causes short-term abnormalities in blood clotting, with thrombosis and embolism occurring in both sexes and all ages immediately following infection. This research has prompted calls from experts to encourage all who have cardiovascular diseases to have an annual flu shot to minimize their risk.

High Blood Pressure Raises Risk of Cognitive Impairment
Approximately 50 million people in the U.S. suffer from hypertension, and what is most concerning is that nearly 15 million people are undiagnosed.
The latest issue of Archives of Neurology has revealed that high blood pressure is associated with an increased risk of mild cognitive impairment-a condition that affects thinking and learning. Nearly 10 of every 1,000 elderly individuals without dementia develop mild cognitive impairment yearly. Of those, 10 percent to 12 percent progress to Alzheimer's disease each year, compared with 1 percent to 2 percent of the general population. During the study, Researchers followed over 900 Medicare recipients age 65 and over without mild cognitive impairment beginning in 1992 through 1994. Participants underwent an initial interview and physical, in addition to tests of cognitive function. They then were examined again every 18 months for an average of 4.7 years.

Birth Control Pill May Raise Risk of Heart Disease
A recent study from Ghent University in Belgium suggests that oral contraceptives - notably high estrogen ones sold decades ago - might increase the chances of having artery buildups that can raise the risk of heart disease. Researchers claim that women who have used oral contraceptives are more likely to have a buildup of plaque in their arteries compared to those women who have not. The main concern for these women is that higher plaque levels increases the risk of a clot developing that can result in a stroke, heart attack, or sudden cardiac death. Though further testing beyond this single study is necessary, it's important due to the sheer scope - 100 million women use birth control pills worldwide.

Link Between Energy Drinks and Heart Disease Risk Found
A recent study presented to the American Heart Association's Scientific Sessions 2007 has found a link between consumption of energy drinks and high blood pressure and heart disease risk. Researchers found healthy adults who drank two cans of a popular energy drink a day had above normal blood pressure and heart rate. Though the observed heart rate and blood pressure increases were not dangerous for healthy volunteers, the results suggest that there could be dangers for patients with heart disease. Energy drinks differ from sports drinks because they contain high levels of caffeine and taurine to increase "energy levels" or alertness. Similar to caffeine, taurine has been shown to increase blood pressure and heart rate.

Diagnosis and Treatment Guidelines For Stable COPD
The American College of Physicians has released an updated clinical practice guideline for the diagnosis and treatment of chronic obstructive pulmonary disease (COPD). COPD is a collection of slowly progressing lung diseases more commonly found in smokers. Over 5% of adults in the US have COPD and it is the fourth primary cause of death and twelfth leading cause of illness. A patient suffering from the disease will typically have a chronic cough, wheezing, and some patients also have a shortness of breath and and activity limitation.
