THEW and Northwestern University collaborate to host Holter ECGs from the DEFINITE Trial in the THEW.
Database: E-HOL-03-0401-017
The purpose of the Defibrillator in Non-Ischemic Cardiomyopathy Treatment Evaluation (DEFINITE) Trial was to determine if
the combination of
ICD therapy to optimal medical therapy reduces all-cause mortality in non-ischemic cardiomyopathy patients with low ejection fraction and
NSVT/PVC's compared to optimal medical therapy only. The enrolled patients in this trial had a diagnosis of nonischemic dilated
cardiomyopathy, a LVEF < 36%, and PVC's or unsustained ventricular tachycardia. The control group received standard medical therapy, while
the test-ICD group received standard medical therapy and a single-chamber ICD. At 2 years, the mortality rate was greater in the control
group (14.1%) than the test-ICD group (7.9%). There were significantly more sudden deaths from arrhythmia in the control group than there
were in the test-ICD group (p=0,006). The investigators concluded that the combination of ICD therapy with standard optimal medical therapy
reduced the risk of sudden death from arrhythmia in patients with severe non-ischemic dilated cardiomyopathy.
We are glad to announce that the Holter ECG recordings acquired in this trial are now hosted in the THEW and are available for
research. Two hundred and thirty nine patients were enrolled in this study and got an Holter ECG recording acquired either at enrollment of
later during the trial, the patients were followed for 29 months in average. The enrollment criteria included LVEF<36%, the presence of
ambient arrhythmias, a history of symptomatic heart failure, and the presence of non-ischemic dilated cardiomyopathy. Ambient arrhythmias were
defined by an episode of non-sustained ventricular tachycardia on Holter (3 to 15 beats at heart rate superior to 120 beats per minutes)
(different from the ECGs hosted in this database). The acquisition of the Holter recordings was initiated after the start of the trial. ECGs
were acquired at baseline or at the next scheduled follow-up visit for patients who were already enrolled in the study.
Importantly, the THEW designed a specific type of research agreement with Northwestern University (Chicago, IL) in order to enable the
distribution of the DEFINITE data to the Scientific community. This agreement includes the involvement of a special committee to review the
research proposal proposed by THEW members. This committee consists of Prof. Alan Kadish, his collaborators and members of the THEW steering
committee. This ad-hoc group will be appointed according to the topics of the research proposal submitted by the THEW members.

The University of Bologna was probably the first University in the western world. Its history is one of great thinkers in science and the humanities, making it an indispensable point of reference in the panorama of European culture. Bologna has thus been called upon to forge relationships with institutions in the most advanced countries to modernise and expand its activity. Among the many challenges which it has met with success, Bologna committed itself to the European dimension which has now led to adoption of the new university system.
