Nearly 2,400 Americans die of cardiovascular disease each day, an average of one death every 36 seconds. Cardiovascular disease claims more lives each year than cancer, chronic lower respiratory diseases, accidents and diabetes mellitus combined. This book summarises the available evidence comparing the efficacy and safety of using ACE inhibitors, ARBs, or their combination vs. standard medical therapy in a population with stable ischemic heart disease, or an ischemic heart disease risk equivalent, and preserved left ventricular function.
