Radionuclide ventriculography allows the visualization of the right and left ventricles, the objective quantitation of right and left ventricular function at rest and during stress, and an evaluation of the influence of a variety of different physiologic, pharmacologic, and surgical interventions on global and regional ventricular function. The further development of tomographic imaging devices and sophisticated associated computer systems should allow sensitive three-dimensional analysis of global and segmental ventricular function and evaluations of the interrelationships between myocardial perfusion, metabolism, and function.

Beyond health promotion: reducing need and demand for medical care.

A population's medical need represents its illness burden. Medical demand represents the service level requested for a particular need. Medical care costs are, in large part, a function of need and demand. Our review of health education programs designed to reduce health risks and reduce costs identified thirty-two programs with documented effectiveness, generally achieving claims reductions of 20 percent. Specific program features including chronic disease self-management, risk reduction, and increased self-efficacy appear important. A broadened definition of health promotion focused on increased personal responsibility for health-related actions and directed at improvement of long-term health outcomes also could reduce health care costs.
