A University of Leeds study looked at UK data from the past 20 years. It found that women were much less likely to be treated for heart attacks and heart failure. And that after the most severe type of heart attack, known as a Stemi, women were 28% less likely to have a coronary angiogram. A potentially life-saving diagnostic tool. Women were also less likely to receive drugs to prevent future heart attacks, such as statins or beta-blockers. And they were significantly more likely to die in hospital after a severe heart attack.
