Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. At least half of heart failure is due to coronary heart disease.
An estimated 5-million Americans suffer from CHF.
According to a 1991 report, several UK physicians suggested that the likelihood of cardiac problems were greater for shorter men. In a study of 2,500 men, the physicians found that those who were 5 feet tall were twice as likely to suffer heart complications as those who were over 6 feet tall. Their explanations for the disparity ranged from differences in nutrition to differences in the size of blood vessels between shorter and taller individuals. The same year, a Danish physician studied 20,000 men and women and declared the UK findings inapplicable to the study of heart complications.
