Congestive heart failure (CHF) occurs when the heart can’t pump enough blood to meet the body’s needs. Symptoms include difficulty breathing, abnormal heart rhythm, extreme fatigue, and muscle weakness. CHF is a leading cause of hospitalization in people over 64. Coffee drinking may decrease the risk of heart failure in aging men and women.
A study from the Pennington Biomedical Research Center in Baton Rouge, Louisiana, showed that coffee drinking decreased the risk of heart failure by as much as 40 percent, particularly in women. Caffeine increases the strength of muscle contractions, but the reason for the link between coffee drinking and a reduced risk of heart failure is unknown. Other recent studies found that coffee drinking protects liver cells and promotes blood sugar metabolism. (Heart, published online; Diabetologia)
