In the United States, chronic diseases are the leading cause of disability and death. While many can be prevented, such diseases are notoriously difficult or even impossible to cure once they have developed. Chronic diseases require on-going medical management. Though serious and ongoing or recurring, in a lot of cases people with chronic diseases can manage their symptoms and live fairly normal lives.
Heart disease is a leading cause of death in many Western nations, including the United States. The term refers to a wide range of conditions and symptoms that affect the heart, from heart defects to coronary artery disease. Heart disease requires continuing medical management. While some conditions are preventable with the implementation of changes to diet and lifestyle, others cannot be. Symptoms of heart disease include tightness in the chest, weakness in the arms or legs, and loss of breath. Heart conditions may be managed with medication, but some people require surgical intervention.
