Iodinated radiologic contrast agents should, ideally, passively provide radiographic contrast in blood vessels and soft tissues but have no effects on physiology, hematology or biochemistry. In practice, no such agent exists although the nonionics most closely approach the ideal. All agents have a bewildering variety of effects on the cardiovascular system, which, in turn, engender a variety of neurogenic and humoral responses. The mechanisms underpinning these many phenomena appear to involve hyperosmolality, molecular structure, ionic content and balance. This review presents the current state of knowledge of these effects and their mechanisms, with emphasis on the differences between conventional ionic and more inert nonionic agents.

Cardiovascular Diseases: Risk Factors
Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
