Introducing the Coronary Health Starter Kit!

 

Dear Friends,

In an effort to make heart scans more widely available, I am delighted to introduce a new service:  AHSF’s Coronary Health Starter Kit.

This service consists of an affordable telephone consultation focused on a cardiac prevention.  As part of this service, I order the famed “mammogram of the heart“, the coronary heart scan that can detect the presence of coronary artery plaques in their early stage, before they cause complications such as heart attacks and sudden cardiac arrest.

I recommend this service for men over age 40 and for women over age 50 (or younger women  if they had premature menopause).  You may consider obtaining the service at an earlier age if you have strong risk factors, such as a family history of coronary disease at a young age. This is a screening service, so it assumes that you feel generally well and have no specific symptoms to report.

I cannot think of a better investment for your heart health than to take advantage of this service and obtain a heart scan.  Please do not delay.  It is as simple as picking up the phone and calling 1-415-567-1014 between 9a-3p to make time for a telephone consultation.Read more

The “mammogram of the heart”

 

The phrase “mammogram of the heart” refers to the heart scan that detects calcium build-up in the coronary arteries.  The phrase was coined by the pioneers in this technology to try to impress on the public and on the medical community the simplicity and value of this test.

Just as a mammogram can identify cancer before it spreads, a heart scan can identify the presence of coronary artery disease before it causes symptoms.  And like the mammogram, the heart scan is easy to perform, uses a low amount of radiation, and is inexpensive.Read more

621 kids screened for heart disease!

 

Desta and I had the pleasure of participating in a heart screening day at Sequoia High School in Redwood City last Sunday.

Volunteer briefing at the start of the day

Volunteers obtaining 12-lead ECG’s

The event was organized by Via Heart Project, a non-profit organization that equips California public schools with AED’s.   Via Heart recently decided to organize heart screenings, and they put a lot of effort and talent into this first event.

They were assisted by the folks at the EP Save-a-Life Foundation, who have been organizing heart screens in the San Diego area for several years and who provided some of the equipment we used, such as the cardiac ultrasound machines.  In total, 203 volunteers helped out, not including the Redwood City Fire Department.Read more

The Widowmaker

 

UPDATE (07/06/2015):  THIS MOVIE IS NOW AVAILABLE ON NETFLIX

Anyone out there concerned about heart disease in yourself or a loved one?

Do me a favor and watch The Widowmaker.  This is the best piece of medical investigative journalism I have ever watched.  It will make you understand what is wrong with heart disease prevention in our broken health care system.

widowmaker-movie

The movie also has great drama, both in the personal testimonies of ordinary folks who have lost a loved one to heart disease, and in the depiction of the political power plays at the highest levels of the cardiology community.

The trailer is below, but it doesn’t begin to give justice to the richness of the movie.  To see the film, click on this link.  You can download it as a rental for $4.99 or buy it for $9.99.  You won’t regret it and I agree with their tag line:  IT COULD SAVE YOUR LIFE.Read more

Demystifying the cardiac stress test

 

For most people, the cardiac stress test is the epitome of modern cardiology.  For some, the thought of undergoing one may also cause cold sweats…Perhaps a little introduction can help clarify what it is and what it does, and will minimize any misplaced fear about this helpful diagnostic tool.Read more

What should your pulse rate be?

The topic of the pulse rate is one that our patients and healthy athletes frequently like to discuss with us.

With the increased availability and ease of use of wearable monitors, the optimal exercise heart rate has become an almost universal subject of conversation, not only in the athletic community but also among those who are just embarking on an exercise program.

In general, athletes are interested in the pulse rate in 2 situations:  the resting pulse rate, best measured upon waking in the morning, and the pulse rate during sustained aerobic exercise, such as running or cycling.  Today we will address the pulse rate during exercise and leave the resting pulse rate for a separate article.

So what is the physiologic meaning of the exercise pulse rate?  Is there a pulse rate one should aim for?  What if the rate falls outside the target zone?  Can the pulse rate ever be a clue to a cardiovascular problem?  Let’s take these questions one by one.Read more

Q&A about high blood pressure during exercise

The adverse effect of lack of exercise on the blood pressure is well known.  A sedentary life frequently leads to chronic hypertension, and in turn, high blood pressure can lead to heart, brain, and kidney damage.

We will address the topic of chronic hypertension in a separate article.  Today, we will discuss a phenomenon called “hypertensive response to exercise” which can occur in seemingly healthy subjects who have no history of hypertension but whose blood pressure during exercise seems to increase “too much.”Read more

Is your job affecting your heart?

Is your job putting you at risk of a heart attack?

As you can imagine, this question has preoccupied epidemiologists and public health specialists for decades.  But despite years of research, straightforward or clear answers are not always available for specific job descriptions.  The medical literature is usually guarded in its assessment of occupational factors leading to heart disease.

Also, if a certain job is linked to an increased risk of heart disease, the job itself may not be the cause of the problem.  For example, risk factors for heart disease (such as smoking) may be more common in certain occupations than in others, making it seem like the job itself imparts the risk.

With this in mind, below are 8 findings that have emerged from years of research:

Can you ever exercise too much?

Professional athletic trainer and sports journalist Ian MacMahan asked us that question as part of an article he published in The Atlantic Monthly magazine.

McMahan reported on recent research that raises concerns about ultra-endurance sports carried to an extreme level for many years.  Such an exercise regimen increases one’s chance of having arrhythmia, such as atrial fibrillation, and may also cause scarring in the ventricle of the heart.

Some cardiologists have sounded alarm bells, comparing such exercise regimens to a “toxin.”  In my opinion, it is not yet clear if long-term, high-intensity exercise alone is the cause of the problem, or if those affected have other factors that come into play.  Nevertheless, the research should not be dismissed.   Here are some highlights:Read more

Outside Magazine highlights value of cardiac screening for athletes

 

In his excellent article on the debate regarding cardiac screening for athletes, Peter Vigneron remarks:

Advanced cardiac screening can reduce the likelihood of sudden cardiac arrest, the most common cause of death among athletes. So why is it so controversial?

We wonder as much!

The key to the controversy has to do with what perspective one adopts.

If one looks at the issue from a public health or population perspective, recommending mass screening for every athlete is logistically daunting, and potential problems (such as false positives and false negative test results) are likely to occur.  There is also an important socioeconomic dimension to the recommendation: who would pay for this?

Furthermore, the cost of comprehensive screening does not have to be as onerous as Vigneron states.  He warns that an echocardiogram (ultrasound study of the heart) can cost up to $2000.  We provide the entire battery of tests for a fraction of that amount!Read more
