The joyful and heartbreaking news of accelerating heart rate and the appearance of angina-like symptoms are signs that researchers have termed "broken heart syndrome", which indicates the impact of the brain on heart function. And that disruption of the management of nerve stimuli plays a role in the incidence of this syndrome.
A team of researchers, under the direction of cardiologist Christian Tempelin of the University Hospital Zurich, has recently found evidence confirming this hypothesis, as well as high stress hormones such as epinephrine or norepinephrine. Similar to heart attack symptoms, such as pain, chest tightness and shortness of breath.
But these symptoms are not caused by the blockage of blood vessels, such as during a heart attack, but by a reduction of the coronary arteries due to stress, which causes a weakness of the heart muscle, which also contributes to high blood pressure. .
The left ventricle of the heart also swells, preventing the heart from pumping blood properly and causing fatal consequences. Doctors therefore recommend that patients be taken to hospital as soon as possible.
"Changes in the brain can be a cause of broken heart syndrome," said Hugo Kattos, chairman of the advisory board of the German Foundation for Heart Disease. .
