Coffee in Moderation May Lower Heart Failure Risk
Two Cups a Day Linked With Best Effect, Researchers Say, but Excessive Drinking Linked With Ill Effects
Coffee and Heart Failure Risk Reduction, Explained?
The health benefits linked with coffee aren't fully understood, Mittleman says. He suspects the reduced heart failure risk is due to coffee's seeming ability to reduce the risk of type 2 diabetes.
Type 2 diabetes is ''directly related to developing heart failure," he says.
Coffee Drinking and Heart Health: Second Opinion
The study is potentially good news, especially for people at risk of heart failure, says cardiologist Arthur Klatsky, MD, adjunct investigator at the Kaiser Permanente Northern California Division of Research and a senior consultant in cardiology for Kaiser.
He reviewed the findings.
"The chief practical application of this study is, people with heart disease at risk of heart failure should not be advised to totally abstain from coffee if they drink moderately," Klatsky says.
Klatsky defines "moderately" as not more than four cups a day.
However, he stresses that "the study does not prove benefit [of coffee in reducing heart failure risk]."
Heart failure is ''the end result of underlying heart disease," Klatsky says. Among the heart problems that can cause heart failure are abnormal heart rhythms, heart valve disease, heart attack, or congenital heart disease, according to the NIH.
