Cardiovascular physiology in the twentieth century: great strides and missed opportunities

In a broad sense, physiology is the study of the chemical and physical bases of life processes. Consequently, the evolution of our knowledge of cardiovascular functions is closely linked to the developments in many fields of science, including chemistry, physics, engineering, and biology. A cursory examination reveals that different "foundation" sciences predominated in different stages of the history of cardiovascular physiology. Today, cardiovascular physiology is poised to exploit new developments in all areas of scientific inquiry. However, cardiovascular physiologists have not always embraced the power of the multidisciplinary approach. In this brief overview of the history of cardiovascular physiology in the 20th century, the major focus is on some of the major advances in the field and the contributions of other disciplines to these developments. In addition, the forces that influenced cardiovascular science in this century and their impact on the evolution of the field in the new millennium are discussed.
