Debate continues as to whether exercise training accelerates the growth of coronary collateral vessels. Animal research has produced positive results, but human studies have been disappointing, largely because of problems in experimental design and methodology. (IAH)

Speculates as to how understanding of heart disease has developed and provides insight into how medical science makes progress. Summarizes the state of knowledge on arteriosclerosis, heart attacks, and exercising the heart. Contains 23 references. (DDR)

Clinical investigations have established that an aggressive approach to lowering cholesterol levels in coronary heart disease patients is warranted. This article describes optimal goals and discusses the role of diet, exercise, and medication in plasma lipids management. (IAH)

The Framingham Heart Study pioneered the concept of risk factors. This article recaps the history of the study, describes poster and essay contests used to commemorate the 40th anniversary of the study, and outlines the involvement of the National Heart, Lung, and Blood Institute in school health research. (Author/MT)

Study supported in part by the U.S. Army Medical Research and Development Command Contract No. DA-49-193-MD-2741.

Discusses possible reasons why the death rate from heart disease is falling. Three phenomena that are considered partly responsible are: (1) early diagnostic technology; (2) the existence of new tools for treating the disease; and (3) public awareness of risk factors. A prescription for a healthy heart is provided. (BC)

Study supported by the Cardiovascular Research Center, University of Michigan, under Grant HE-6378 (National Heart Institute, U.S. Public Health Service) and Grant CD-00246 (U.S. Public Health Service).

Describes an intensive search and analysis of the literature pertaining to cardiovascular disease which led the authors to conclude that a generous portion of the nation's biomedical research dollars should be directed toward basic research. (MLH)

The National Heart, Lung, and Blood Institute, a federal biomedical research agency, contributes to school health education by means of information dissemination and cooperation with schools and other agencies to apply research findings to health education programs. (CJ)

This study attempted to (1) determine whether stroke patients (n=20) can safely increase their walking speed above that of comfortable walking; (2) describe the relationship between comfortable and maximum safe walking speed; and (3) examine correlations between maximum and comfortable speeds and a functional walking score. Subjects were able to…

Described is a new approach to investigative physiology based on computerized transaxial tomography, in which visualization and measurement of the internal structure of the cardiopulmonary system is possible without postmortem, biopsy, or vivisection procedures. Examples are given for application of the Dynamic Spatial Reconstructor (DSR). (CS)

This paper presents epidemiologic evidence on the contributions of physical inactivity and reduced cardiorespiratory fitness to risk of coronary heart disease (CHD). The types and dose of physical activity to reduce risk of CHD and plausible biologic mechanisms for the partial protective effect are reviewed. (Author/SM)

The document contains the papers presented at the 5th Congress of the World Federation of Hemophilia in Montreal in 1968. Seven papers concern specific therapy of hemophilia, five papers treat nonspecific forms of therapy, seven papers deal with prophylaxis and complications in hemophilia, seven others deal with orthopedic and other surgical…

The roles of the school, health education programs, and health education research in decreasing the risk of cardiovascular and heart disease are discussed. (CJ)
