Researchers from the National University of Ireland Galway, in a fresh study identified two factors that may trigger a stroke, which are extreme physical exertion or strong feelings of anger or emotional upset.

Andrew Smyth, one of the researchers, pointed out that medical professionals are continuously trying to determine how to better predict when strokes will occur and that his team鈥檚 work may be able to provide a helpful, new perspective.

Smyth said: 鈥淢any studies have focused on medium to long-term exposures, such as hypertension, obesity, or smoking. Our study aimed to look at acute exposures that may act as triggers.鈥�

In knowing the risks for the study, the researchers analysed data from the 鈥業nterstroke鈥� study, which includes information on more than 13,000 cases of strokes from 32 countries, agency report said

The team was most interested in revealing patterns among stroke patients to better understand some of the factors that trigger the condition.

The study was focused on patients who had ischemic strokes and intracerebral hemorrhages.

So, in order to understand if one of the risk factors led to a stroke, it had to occur within one hour of when the patient started experiencing stroke symptoms.

The researchers compared that information with how the patient responded at the same time the day prior to the stroke.

The team identified episodes of anger or emotional upset and heavy physical exertion as two triggers that may incite a stroke.

One in 11 patients experienced emotional disturbances prior to their stroke, and one in 20 had engaged in serious physical activity.

Smyth also stated: 鈥淲e looked at two separate triggers.

Our research found that anger or emotional upset was linked to an approximately 30% increase in risk of stroke during one hour after an episode 鈥� with a greater increase if the patient did not have a history of depression. The odds were also greater for those with a lower level of education.鈥�

He as well noted: 鈥淲e also found that heavy physical exertion was linked to an approximately 60% increase in risk of intracerebral hemorrhage during the one-hour after the episode of heavy exertion.

鈥淭here was a greater increase for women and less risk for those with a normal Body Mass Index (BMI).

鈥淭he study also concluded that there was no increase with exposure to both triggers of anger and heavy physical exertion.鈥�

Following a healthy lifestyle

Whereas knowing these triggers may help consumers lower their risk of having a stroke, the researchers yet emphasised that following a healthy lifestyle is critical for long-term health outcomes.

Researcher Martin O鈥橠onnell said: 鈥淪ome of the best ways to prevent a stroke are to maintain a healthy lifestyle, treat high blood pressure, and not to smoke, but our research also shows other events such as an episode of anger or upset or a period of heavy physical exertion independently increase the short-term risk.

鈥淲e would emphasise that a brief episode of heavy physical exertion is different to getting regular physical activity, which reduces the long-term risk of stroke.鈥�
