As per a new study stress hormones affect male and female hearts differently

According to a recent study published in Science Advances, the hearts of men and women react differently to the stress hormone noradrenaline. In the research done on rats, it was seen what effect heart failure and drugs can have on different genders.

The team created a new type of fluorescence imaging system that allowed them to use light to see how the rats’ hearts responded to hormones and neurotransmitters in real time. The rats were exposed to noradrenaline, also known as norepinephrine.

The results revealed that after exposure to noradrenaline, the hearts of male and female rats first reacted similarly. However, some regions of the female heart normalised more quickly than those of the male heart, which creates differences in the heart's electrical activity.
