M. Josephson et S. Nisam, PROSPECTIVE TRIALS OF IMPLANTABLE CARDIOVERTER-DEFIBRILLATORS VERSUS DRUGS - ARE THEY ADDRESSING THE RIGHT QUESTION, The American journal of cardiology, 77(10), 1996, pp. 859
There is already considerable evidence that the implantable cardiovert
er-defibrillator prolongs life in properly selected patients (remarkab
ly, there is no evidence to the contrary). Studies that are under way
and those being planned need to focus on other important issues (e.g.,
clinical and health-economic) rather than on questions that have alre
ady been answered.
