I think one of the greatest public safety advances of the last 15 years has been the widespread installation of automated external defibrillators (AEDs). Automated external defibrillators are medical devices designed to deliver an electrical shock to the heart in ventricular fibrillation – a cardiac rhythm that is commonly associated with cardiac arrest.

I was working in emergency medicine when medical device companies first began to advocate for the placement of AEDs in public places and worked closely with many companies, organizations, and government agencies to incorporate AEDs into their emergency response plans. This wasn’t an easy sell in the late 1990s. People were worried about safety, liability, and cost. But, AED programs have been a great success. AEDs are most effective when they are used within 3-5 minutes of arrest. For example, if you have a cardiac arrest with ventricular fibrillation in New York City, Read more »

Those who market heart scan services should be more careful about what they promote and to whom.
When ProPublica’s Marshall Allen got a telemarketing offer for heart scans for him and his wife, he followed up with a story, “Body Imaging Business Pushes Scans Many Don’t Need – Including Me.”
Reminding Allen about the deaths of figure skater Sergei Grinkov, baseball player Darryl Kile, newsman Tim Russert and actor Patrick Swayze, the salesman said:
“You never know when it could happen. … Boom, you’re dead!” he exclaimed, slapping a desk for emphasis.
But Allen tells another story – of complaints by patients and regulators about the business. Read more »

When cyclists find out that I am a heart doctor, they most frequently ask about cholesterol numbers.
“…My cholesterol is this…What do you think?”
“…My doctor wants me to take a statin…But I read that these drugs might lower my functional threshold power 2.014 watts/40km.”
All this focus on numbers saddens me. Remember, I am a forest guy, not a tree guy. What’s more, as a doctor that revels in the adrenaline rush of ablating rogue circuits with technology that would impress even a twenty-something, I find questions about biochemistry dreary–like eating quinoa.
I wish folks would ask me about how to terminate AF with a catheter, or how an (evidenced-based) ICD saved a mom’s life, or perhaps even this: “Do you do heart surgery?”
But more often than not people want to know about cholesterol.
Okay. It just so happens that this week brought some very interesting news concerning the treatment of abnormal cholesterol lab values. News that big-picture docs have to like. Read more »

Ready to learn more about nurses who work beyond the bedside? Nurses who work in the Cardiac Catheterization Lab (CCL) play an important role in cardiac care. Amy Sellers, RN BSN CCRN CSC CMC blogs at Nursing Influence and graciously agreed to give us a peek at what a nurse is responsible for doing in the CCL.
Amy has worked in the Cath Lab for about 6 months now. She previously worked in CVICU for almost 5 years before deciding that she needed a new challenge. She is paid hourly and works three 12 hour shifts per week (all daytime Mon-Fri) with lots of opportunities for overtime and call shifts.
A cath lab is an area of the hospital that uses fluoroscopy and contrast dye to check for narrowing/blockages in arteries or veins in the body. Using special equipment, they are able to perform angioplasty (open the arteries with a balloon), place stents, insert IVC filters (a filter that is inserted into a large vein which prevents blood clots that form in the leg from getting to the lungs) as well as inserting pacemakers/ICDs. ICDs are Implantable Cardiac Defibrillators. They detect if a patient’s heart goes into a lethal rhythm and provides a shock to the heart if necessary to get it beating correctly again.

It was just a visit to manage her paroxysmal atrial fibrillation. She was long overdue for the visit. So she arrived as she had so many times before: with little fanfare and folderol. She sat patiently after her weight was obtained, vitals recorded, and medications verified. Clutching her purse, whe sat patiently as the examination door opened.
“Hello, Ms. Smith, how have you been doing?”
“Wonderfully, doctor. I haven’t had any more problems with my heart rhythm.” She leaned sideways to put down her purse on the floor next to her.
“Any dizziness, lightheadedness, shortness of breath, cough?…”
“No, I’m doing fine, thankfully,” her eyes glistening.
I proceeded to complete her history and catch up on a few details with her, then moved on to the physical examination. I watched as she got up on the exam table and noted her moving a bit more slowly than I had recalled.
“Is your strength doing okay?”
“Oh sure. Never better. Just slowing down a bit is all. But I’m not sure how well I’d be doing if it weren’t for my daughter.”
“How’s that?” Read more »
