Abstract: |
Cardiovascular disease is responsible for ~ 33% of all deaths in the USA (Heart Facts 2012) [1]. Approximately 28% (83 million people) of the US population has one or more forms of acquired heart or blood-vessel disease. Elevated blood pressure (hypertension) is present in 64 million adults, coronary artery disease in 16.3 million (9 million with angina or chest pain of cardiac origin), congestive heart failure (HF) in ~ 5.7 million, and stroke in 7 million. In 2008, coronary artery disease (CAD) caused ~405,000 deaths in the United States, making it the number one killer. About 1.2 million people will suffer a new or recurrent heart attack each year. In addition to CAD, HF (inability of the heart to pump sufficient blood to meet the demands of the body) is becoming more prevalent. © Springer-Verlag Italia 2013. |
