Molecular imaging identifies high-risk patients with heart disease
Date:8/10/2010

Reston, Va.A study published in the August Journal of Nuclear Medicine (JNM) finds that molecular imaginga non-invasive imaging procedurecan identify high-risk patients with potentially life-threatening cardiovascular conditions and help physicians determine which patients are best suited for implantable cardioverter defibrillator (ICD) therapy.

"If the molecular imaging techniques are used for appropriate selection of ICD candidates, not only overuse but also underuse of ICD could be avoided and the assessment may be shown to be more cost-effective," said Kimio Nishisato, M.D., a physician in the cardiology division of Muroram City General Hospital, Muroram, Japan, and corresponding author for the study.

According to researchers from Sapporo University, Sapporo, Japan, the study shows that molecular imaging can play an important role in diagnosing and guiding the treatment strategy for arrhythmia, coronary artery disease and heart failure.

"This research holds significant potential for the detection, diagnosis and treatment of many common cardiovascular conditions," said Tomoaki Nakata, M.D., Ph.D., an associate professor at the Sapporo Medical University School of Medicine and director of the Hokkaido Prefectural Esashi Hospital, Japan. "With molecular imaging, physicians can improve patient care by pinpointing the precise location of the disease in order to eliminate the need for invasive medical devices and unnecessary surgical techniques." Nakata adds that molecular imaging can also reduce unnecessary medical costs by better targeting treatment for each individual patient.

In this study, researchers hypothesized that both the impairment of myocardial perfusion and/or cell viability and cardiac sympathetic innervations are responsible for heart arrhythmia and sudden cardiac death. However, there was no established reliable method, including a molecular imaging technique which is highly objective, reproducible and
