Yes. When you’re overwhelmed with stress, your body goes into “fight-or-flight” mode, which triggers your adrenal glands to release the hormones cortisol and adrenaline. These can make your heart beat faster and your blood pressure rise.
This usually happens when there’s a momentary stressor, and the effects pass once it’s over. However, over time, too many episodes of this kind of acute stress can cause inflammation in your arteries, which could be a contributing factor to heart attacks.
