Anxiety Increases the Risk of Heart AttackAs men age, their risk of heart attack rises, especially if they are prone to anxiety. In a 12-year study, anxiety was found to increase the risk of heart attack by 30% to 40% in men who are anxious when compared to men who are calmer, irrespective of other personality and risk factors. In this...
