This contributed volume focuses on cardiovascular diseases (CVDs), and explores the ways in which signaling mechanisms at the biochemical, molecular, and cellular levels in the blood vessels (vascular) and heart contribute to the underlying causes of development and progression of the CVDs. This volume covers unique topics such as oxidant signaling in vascular and heart diseases and health, cytoskeletal signaling in vascular health and disease, phospholipase signaling in CVDs, lipid signaling in vascular and myocardial health and diseases, and drug discovery in cellular signaling for cardiovascular diseases. This book assembles the most important discoveries made by leaders on the cellular signaling mechanisms operating behind the development and progression of life-threatening CVDs. It is an extremely useful resource for the investigators in the field of CVDs, and opens the discussion for further discovery of efficient management and effective treatment of the CVDs.
