All good physicians want to do the right thing. They want to recommend effective therapies to their patients that will improve outcomes or alleviate symptoms. It is widely accepted that the best way to discover new effective therapies is through the use of clinical trials. Among clinical trials, the reference standard is the randomized, double-blinded, placebo-controlled trial, which is designed to minimize bias in the selection of therapies or the interpretation of results.
I have written before about the limitations of clinical research in advancing medical practice. As I have said, it is literally impossible to study every clinically relevant question, and it is also impossible even in theory to use randomized controlled trials as the methodology for many of the questions that can be studied.
A recent article in the New York Times highlighted another challenge to the paradigm of clinical trials as the engine for improving medical practice. The piece was about a change in policy at the National Institutes of Health, being implemented by Michael Lauer, the “newly appointed deputy director for extramural research.” In the interest of full disclosure, I have known Mike for many years (we were cardiology fellows in the same program at Boston’s Beth Israel Hospital in the late 1980’s) and you would be hard-pressed to find a nicer, smarter or more upstanding guy.

What does someone having a heart attack look like? I think the New York Times captured what many of us probably have in mind, when they published this picture as part of a recent series on advances in cardiovascular care:

Here is the iconic middle-aged guy, in extremis, pointing to his chest, with a team of health care professionals at the bedside. There are also signs of initial management – he has ECG electrodes on his chest, an IV in his left arm, what looks like monitor/defibrillator pads on his right chest and below his left arm and, of course, an oxygen mask.
What is wrong with this picture?

Every so often I come across a research paper that leaves me feeling as if I am glimpsing the future. I had that experience when I came across the work of Cingolani and colleagues in the December 23 issue of the Journal of the American College of Cardiology (volume 64, no. 24). The paper, entitled “Engineered electrical conduction tract restores conduction in complete heart block: from in vitro to in vivo proof of concept” details a new approach to an old problem.
Here’s the problem. Many people develop serious disturbances of the heart rhythm based on deterioration or destruction of specialized “conduction tissue” within the heart. This tissue is responsible for transmitting the electrical impulses that govern the beating of the heart. In the case of the dysfunction of conduction tissue between the atria and ventricles, the chambers become electrically and mechanically dissociated – a condition termed complete heart block, and generally treated with an implanted pacemaker.

There is an old gag about an intensely optimistic child whose bright outlook on life is so irrepressible that when he is presented with a room full of manure for Christmas, he screams with delight, convinced that there “must be pony in there someplace.” Continue reading Looking for the Pony
