Coffee ‘may reduce risk of heart attack’, data from three large studies suggests

Drinking between one and three cups of caffeinated coffee a day could reduce the risk of heart failure risk, according to new research based on three long-running heart disease studies examining the health outcomes of tens of thousands of people.

Coronary artery disease, heart failure and stroke are among the top causes of death worldwide, but scientists say the lifestyle elements which can lead to these serious conditions are not yet fully understood.

“While smoking, age and high blood pressure are among the most well-known heart disease risk factors, unidentified risk factors for heart disease remain," said David Kao, senior author of the study, and assistant professor of cardiology at the University of Colorado School of Medicine in Aurora, Colorado.
