What is the leading cause of death in the United States? Heart disease? Cancer? No, it’s smoking. Smoking? Yes, depending on how you ask the question.
In the early 90s, McGinnis and Foege turned the age-old question of what people die of on its head by asking not what diseases people die of but rather what the causes of these are. Instead of chalking up the death of an older man to say lung cancer, they sought to understand the proximate cause of death, which in the case of lung cancer is largely smoking. Using published data, the researchers performed a simple but profound calculation — they multiplied the mortality rates of leading diseases by the cause-attributable fraction, that proportion of a disease that can be attributed to a particular cause (for example, in lung cancer 90 percent of deaths in men and 80 percent of deaths in women are attributable to smoking). Published in JAMA in 1993, their landmark study became a call to action for the public health community.
When looked at the conventional way, using data from the 2004 update of the original study, heart disease, cancer, and stroke are the leading causes of death, respectively. This accounting may help us understand the nation’s burden of illness, but does little to tell us how to prevent these diseases and improve health. Through the lens of McGinnis and Foege we get the actual causes of death (e.g., the major external modifiable factors that contribute to death). This analysis shows that the number one cause of death in America is tobacco use, followed closely by poor diet and lack of physical activity, and then alcohol consumption. Read more »

It’s hard to believe that turbulence could be a good thing for the heart. Consider how the word turbulent is defined: “Characterized by conflict, disorder, or confusion; not controlled or calm.” Those traits don’t sound very heart-healthy. But when it comes to heart rhythm, it turns out that a turbulent response — to a premature beat — is better than a blunted one. The more turbulent the better.
No, you haven’t missed anything, and turbulence isn’t another of my typos. Until [recently], heart rate turbulence was an obscure phenomenon buried in the bowels of heart rhythm journals.
What Is Heart Rate Turbulence (HRT)?
When you listen to the heart of a young physically-fit patient, you are struck not just by the slowness of the heartbeat, but also by the variability of the rhythm. It isn’t perfectly regular, nor is it chaotic like atrial fibrillation (AF). Doctors describe this — in typical medical speak — as regularly irregular: The heart rate increases as the patient inhales and slows as he or she exhales. This variability occurs as a result of the heart’s responsiveness to its environment. The more robustly and quickly the heart responds, the healthier it is.
HRT seeks to measure how quickly and vigorously the heart rate reacts in response to a single premature beat from the ventricle — a premature ventricular contraction (PVC). Normally after a PVC, the heart rate speeds for a few beats, and then slows back to baseline over the next 10 beats. The healthy heart responds with a more intense rise in heart rate and a quicker return to baseline. Using simple measurements of heart rate from a standard 24-hour electrocardiogram (ECG) monitor, a propriety software program averages many of these responses and comes up with a measurement of turbulence onset and turbulence slope.

This is the time of year when stores are filled with red hearts and other reminders that Valentine’s Day is approaching. It’s a mood booster, not to mention a nice break from all that winter grey (at least up here in Boston). After all, what would life be like without romance, love — and sex?
Unfortunately, a variety of health problems — as well as some of the treatments for them — can get in the way of sexual desire and functioning. Here’s a quick look at some of the main sources of trouble and suggestions about what to try first. If these initial strategies don’t work, have a heart to heart with your doctor about what to do next. There may not be a quick fix for health-related sexual problems, but there are steps you can take to help ensure that you can still enjoy a love life while taking care of the rest of your health.
Arthritis
Arthritis comes in many guises, but most forms of this disease cause joints to become stiff and painful. The limitations on movement can interfere with sexual intimacy — especially in people with arthritis of the knees, hips, or spine.
One common solution is to try different positions to find a way to make sex physically more comfortable. Another option is to take a painkiller or a warm shower before sex to ease muscle pain and joint stiffness. Or try a waterbed — which will move with you.

Cancer
Cancer treatment may have long-term impact on sexual desire and functioning. Surgery or radiation in the pelvic region, for example, can damage nerves, leading to loss of sensation and inability to have an orgasm in women and erectile dysfunction in men. Chemotherapy can lower sex drive in both men and women. Read more »

From the Dallas Morning News, a creative moniker if there ever was one, but it should probably be reserved for primary care specialists instead:
DALLAS — Heart attacks are the No. 1 cause of death and a major cause of disability in America. For nearly half of the casualties, the first symptom is the last. That’s how cardiovascular disease has earned the nickname “silent killer” — you never know when it will strike.
Doctors are trying to change that by treating heart disease as a progressive problem. They are becoming “heart whisperers,” seeking new tests to read the small stresses that can, unchecked, grow into big ones.
“By the time someone rolls in with a heart attack, his family will look at me bewildered, and the patient may say, ‘Doc, what happened?'” says Dr. Bruce Gordon of Heart Hospital Baylor Plano. “But it’s not what happened. It’s what’s been happening. The process has been going on for decades.”
It’s a process that can be accelerated by high cholesterol, high blood pressure, obesity, diabetes, tobacco use and secondhand smoke.

Heart disease and February: What relationship could be more cozy? From the scary risks of shoveling snow (yep, you could die, so be sure to lift a little at a time), Mercedes-sponsored red dress parades and government-sponsored National Wear Red Day®, to tips for identifying heart attacks in women (men, you need a different month I guess), February has all the important stories to improve your awareness. Such a polite term “awareness.”
But I wonder, now that the Internet is upon us and people are seeing their insurance rates and co-pays skyrocket, if maybe we’re shooting ourselves in the foot with all this heart-month marketing hype. People are sick and tired of testing “just to be sure.” It’s starting to directly cost them a fortune, and people are frustrated at having to pay a fortune for healthcare, let alone heart care.
I know, I know — I should be at the forefront of working with patients to stomp out heart disease. And goodness, people DO need to be attuned to diet, exercise, and weight loss. But the reality is, if we’re giving you the 10 latest tips on how to detect a heart attack, we’re probably a bit too late.
That’s the problem with all these press releases: While there’s a need to raise “awareness” of heart health, there’s also a very real need for people to take us — heart disease professionals — seriously to help cut costs in healthcare here. The last thing our healthcare system needs is more frivolous testing. Yet this is exactly what all this marketing does for our healthcare system — and it helps those with the largest PR budgets most of all. Read more »
