The end of the year marks a time for list-intensive posts. Recently Larry Husten from CardioExchange and CardioBrief asked for my opinion on the three most important cardiology-related news stories of 2010. Additionally, he wanted three predictions for 2011. Here goes:
Top Cardiology Stories Of 2010:
1. By far, the #1 heart story of 2010 was the release of the novel blood-thinning drug dabigatran (Pradaxa) for the prevention of stroke in atrial fibrillation. Until this October, the only way to reduce stroke risk in AF was warfarin, the active ingredient in rat poison. Assuming that there aren’t any post-market surprises, Pradaxa figures to be a true blockbuster. Doctors and patients have waited a long time to say goodbye to warfarin.
2. The Dr. Mark Midei stent story: Whether Dr. Midei is guilty or innocent of implanting hundreds of unnecessary stents isn’t really the big story. The real impact of this well-chronicled saga is the attention that it brings to the therapeutic misconceptions of coronary stenting. The problem with squishing and stenting is that although they improve the physics (of bloodflow), they do not change the biology of arterial disease — a hard concept to grasp when staring at a picture of a partial blockage. The vast press coverage of Dr. Midei’s alleged transgressions has served to educate many about heart disease, the nation’s #1 killer. Read more »

Stroke killed 2,000 fewer Americans in 2008 (the last year with complete numbers) than it did in 2007, the Centers for Disease Control and Prevention (CDC) said yesterday in its latest annual Deaths report. That dropped stroke from the third leading cause of death in the United States to the fourth.
Good news? Yes and no. It’s always good news when fewer people die. The reduction suggests a payoff for efforts to prevent stroke and improve the way doctors treat it.
Yet the drop from third to fourth place is due largely to an accounting change. The CDC reorganized another category, “chronic lower respiratory diseases” (mainly chronic bronchitis and emphysema), to include complications of these diseases such as pneumonia. The change substantially increased the number of deaths in this category, which had long trailed stroke as the fourth leading cause of death.
More worrisome is that the decline in deaths from stroke isn’t matched by a decline in the number of strokes. On the rise since 1988, stroke now strikes almost 800,000 Americans a year, and that is expected to grow. Read more »

A mom who took care of us kids far better than she did herself, always. A Dad whose advice grew better with years, although it was good then. Two brothers and a sister to share a driveway basketball court with, rain or shine. The infinite love of grandparents, who lived within hollering distance over an old Connecticut stone wall.
A high school guidance counselor who said I wasn’t smart enough to go to medical school. A college biology professor who rolled out a cart of beers on that first Friday evening research conference. That I watched the movie “Hoosiers” and thought to look at Indiana University for residency, and while there met so many dedicated cardiology teachers.
That I have so many great colleagues to work with now. Immersing oneself in a sea of committed people helps the heart. Medical peeps are a cool crowd. That technological wizardry has allowed us on opportunity to alleviate the heart’s most common hiccup, the AF.
That our family has found some great pals to hang with. Friends that allow us to wear tank tops, shorts and crocs with socks when we visit. But most of all, I am thankful for a family that I would not change one bit — a loving wife who is a best friend, and smart healthy kids who like themselves, each other, and their parents (at least most of the time).
Thanksgiving.

Oops…I am thankful that I am a master bike racer, too. Only I wish that I was faster.

New clinical trials and published research are giving us information on how to improve health in elderly patients. Here are some brief points from the Cleveland Journal of Medicine that were surprising to me:
— Each year 30 percent of people age 65 or older fall and sustain serious injuries so preventing falls and fractures is important. Vitamin D prevents both falls and fractures, but mega doses of Vitamin D (50,000 mg) might cause more falls. A better dose is 1,000mg a day in people who consume a low-calcium diet.
— Exercise boosts the effect of influenza vaccine.
— The benefits of dialysis in older patients is uncertain, as it does not improve function in people over age 80. We don’t even know if it improves survival. Older patients who receive dialysis for kidney failure had a decline in function (eating, bed mobility, ambulation, toileting, hygiene, and dressing) after starting treatment.
— Colinesterase inhibitors (Aricept, Razadyne and Exelon) are commonly used to treat Alzheimer disease, but they all can have serious side effects. Syncope (fainting), hip fractures, slow heart rate, and the need for permanent pacemaker insertion were more frequent in people taking these drugs. The benefits of these drugs on cognition is modest.
— A new drug called Pradaxa (dabigatran) will likely prove to be safer than Coumadin (warfarin). Over two million adults have atrial fibrillation and the median age is 75. The blood thinner warfarin is critical for prevention of strokes but it caries a high risk of bleeding and drug levels have to be monitored frequently. Dabigatran will probably replace warfarin, but it will probably also be a lot more expensive.
As I often say, medicine and science are constantly changing and evolving. As new evidence comes forth, physicians and patients need to re-evaluate they way we do things.

I loved my old status. Perhaps, reveled in it would be a better description. I was a crotchety, generic medicine-only doctor.** Sadly, my status changed today. Dabigatran (brand name Pradaxa) was the culprit.
It was a little nerve racking. I wrote the order, looked at it, thought it out again, talking to myself: “John, are you sure you don’t want to do it the old way? [pause to think] No, I am embracing the new.” And then, I closed the chart and handed it to the nurse.
“What’s that? Pradaxa?” asked the nurse. “Stop the Lovenox? You sure?” My face must have told the story.
Eight days had passed since dabigatran’s approval. “That’s plenty of time to mourn warfarin’s demise,” I thought. Enough studies, enough blogs — it was time for the rubber to hit the road. Read more »
