Objective: Cardiac resynchronization therapy (CRT), in addition to optimal medical therapy, is an approved treatment for patients with coronary artery disease (CAD) and advanced heart failure (HF). Electrical dyssynchrony as determined by QRS duration is currently applied to select the patients for CRT; however, it may not necessarily represent mechanical dyssynchrony and therefore may not necessarily represent patient response to CRT. Some other factors may be related to the dyssynchrony of the left ventricle. The current study is designed to evaluate the relationship between mechanical dyssynchrony and some other factors such as CAD risk factors and myocardial perfusion indices. 
Materials and Methods: One-hundred and three patients with angiographically proven CAD and heart failure entered in the study. Gated myocardial perfusion imaging (MPI) using Tc-99m MIBI and quantitative perfusion, function and phase analyses was carried out for each patient. Phase standard deviation (PSD), phase histogram bandwidth (PHB), left ventricular ejection fraction (LVEF), summed rest/stress perfusion scores (SRS/SSS) and summed difference perfusion score (SDS) were calculated according to quantitative perfusion SPECT (QPS) and quantitative gated SPECT (QGS) software. 
Results: Both parameters of phase analyses, i.e. PSD and PHB showed significant correlations with SSS (r=0.61, p<0.001, r=0.64, p<0.001, respectively). There are also significant correlations of PSD and PHB with SRS (r=0.56, p<0.001 & r=0.58, p<0.001, respectively) but not with SDS (p=0.635, p=0.563). Among different factors such as QRS duration, LVEF <35% vs. 35-45%, SSS, SRS, territory of coronary stenosis and the risk factors of CAD such as diabetes mellitus, hypertension and obesity , the only independent factors affecting the severity of mechanical dyssynchrony were EF, SSS and SRS. 
Conclusions: MPI with perfusion, function and phase analyses can be used to select the best candidates for CRT in CAD patients with heart failure. The patients with EF<35% and those with EF of about 35-45% concomitant with SRS>20, regardless of CAD territory, QRS duration, and CAD risk factors, are associated with more severe dyssynchrony and thus may be good candidates for CRT.

The Congress Reporting Form
How many volunteers were present at the Congress? : About 1000
Delegates from which countries presented in the congress? : The organizer was World federation of Nuclear Medicine and Biology and delegates from about 50 countries were presented in the congress including Iran, Mexico, USA, Brazil, France, Swiss, Germany, Austria, Denmark, Canada, Italy, Spain, Australia, Japan, India, China, Singapore, Indonesia, North Korea, Thailand, Kuwait, Bangladesh, ....
Were the delegates of any other organizations present in the congress? : Yes
If yes, please write the names of the organizations in the box : IAEA, EANM, SNM
What were the responses to your talking points? Were specific questions or concerns raised? : I presented 2 research works upon two different topics. One of them was considered a lot. Also all of the scientific questions were directly answered.
If you met staff members, please list their full names & positions. : Dr. Enrique Estrada Lobato, President, World Federation of Nuclear Medicine and Biology
Please inform us if there are any follow up actions we need to talk with the members of the congress : Our colleagues will follow the new ways for further collaboration and also we were often volunteers for holding the great meeting in the field of our specialty. For instance, the head of ISNM from Iran was elected as the 10th President of the Asia Oseania Federation at the 9th AOFNMB Governing Council meeting which was held during the 9th Congress and consequently the tenth congress was held in Tehran, Iran in May 16-20, 2012. Organizers were President Dr. Mohsen Saghari, Vice President and Chair of the scientific committee Dr. Mohammad Eftekhari, and Chair of organizing Comittee, Me (Dr. Babak Fallahi). The theme was ‘Nuclear Medicine All Over The World’. The total number of participants was 1027 from 36 countries, 382 papers were presented and the congress was very successful. However, we have a far way to go to achieve better communications and sharing of knowledge and experiences among the researchers and academic members, better education and training, and promotion of nuclear medicine practice in the world especially in our country.
Your experiences about the travel processes(Providing ticket, accommodation,...) : This was a very long-distance travel; A tour- travel company prepared all requirements including air-tickets and accomodation arrangements.
Please give a briefing of your own observations and outcomes of the congress: : The WFNMB organizes a quadrennial Congress, the third largest nuclear medicine meeting world-wide. The current WFNMB Congress was held in Cancun, Mexico, and received more than 1000 attendees. The diversity of participating countries (85 countries) and participation of scientists and experts in the field of nuclear medicine was given a good credibility to the Congress. In addition, several scientific programs at the meeting were presented such as Plenary Sessions, Symposia, Continuing Medical Educations, Categorical Seminars, and World Summits

Congress committees put great effort into providing us with state-of-the-art Continuous Medical Education sessions, enhanced by interactive sessions. There was a long list of guest speakers who had lecture in the multidisciplinary joint symposia where the committees provided an insight into the collaborations they have established outside of nuclear medicine. The latest achievements in clinical nuclear medicine, science and technology presented and discussed during oral and poster sessions. In addition, several scientific programs at the meeting were presented such as Plenary Sessions, Symposia, Continuing Medical Educations, Categorical Seminars, and World Summits. At the end of the meeting, the tradition of summarizing the meeting highlights in order to provide us with a broad overview of the science presented at the congress. The next global participation and interaction will be in Australia, 2018.
