Losing one’s temper or exercising too much could be contributing factors for stroke, according to new research.

In a study published Wednesday in the “European Heart Journal” of the European Society of Cardiology, a team of international researchers looked at more than 13,000 stroke patients in 32 countries as part of the Interstroke study.

using a “case-crossover approach,” The team determined whether a trigger was associated with an acute stroke within an hour of symptom onset, versus the same period of the previous day.

“Stroke prevention is a priority for physicians, and despite progress it is difficult to predict when a stroke will occur. Many studies have focused on medium- to long-term risks, such as high blood pressure, obesity or smoking. Our study The aim is to look at acute exposures that may act as triggers,” said lead researcher and Professor Andrew Smyth from the National University of Ireland Galway said in a statement.

The research analyzed patterns in patients who ischemic stroke and less common intracerebral hemorrhage.

One in 11 survivors experienced periods of anger or upset within an hour, and the global Interstroke study found that one in 20 patients had done heavy physical exertion.

The paper, co-led by the National University of Ireland Galway, suggested that anger or emotional distress was associated with an almost 30% increase in stroke risk during the one hour following an episode – a greater increase if the patient had not. with a history of depression and major barriers for people with a low level of education.

Heavy physical exertion was associated with an approximately 60% increase in the risk of intracerebral hemorrhage (ICH) – a rare form of stroke that causes bleeding in the brain – after heavy exertion during the same period but of all strokes or ischemic strokes. with not.

There was a greater increase for women and a lower risk for those with a normal body mass index (BMI).

“Acute anger or emotional distress was associated with the onset of all stroke, ischemic stroke and ICH, whereas intense heavy physical exertion was associated with ICH only,” the authors wrote.

“The study also concluded that there was no increase in exposure to both triggers of anger and heavy physical exertion,” Smith said.

The study reported that there was no modifying effect based on region, prior heart disease, risk factors, cardiovascular medications, time of symptom onset, or day.

“The likelihood of stroke was not additive by exposure to both triggers, compared to exposure to neither trigger during the control period,” the study said.

Dr. Michelle Canavan, co-author and consultant stroke physician at Galway University Hospitals, said that people at all ages should practice mental and physical health, but added that “for some people avoiding heavy physical exertion may also important, especially if they are high- risk of cardiovascular disease, even when adopting a healthy lifestyle of regular exercise.”

in America, The Centers for Disease Control and Prevention (CDC) says Every 40 seconds someone has a stroke and every four minutes someone dies from a stroke.

About 800,000 people have a stroke each year in the US. about 87, All strokes are ischemic strokes, in which blood flow to the brain is blocked.

“Some of the best ways to prevent stroke are to maintain a healthy lifestyle, treat high blood pressure, and not smoke, but our research shows other events such as being angry or upset or periods of heavy physical exertion can increase independently. “Short-term risk.” Study co-leader and Professor Martin O’Donnell from the National University of Ireland Galway said.

“We would emphasize that a brief episode of heavy physical exertion is different to getting regular physical activity, which reduces the long-term risk of stroke,” he explained.
