Stress May Be Tougher on Women’s Hearts Than Men’s: Study Preliminary research found blood flow doesn’t rise in women, possibly raising their cardiac risk TUESDAY, April 24 (HealthDay News) — Heart blood flow increases in men when they experience mental stress, but does not change in women, a small new study suggests. The finding may explain why women are more likely than men to have heart trouble when they suffer emotional distress, the Penn State College of Medicine researchers said. The investigators measured heart rate, blood pressure and heart blood flow in 17 healthy adults — a near-equal mix of men and women — at rest and while they did three minutes of mental arithmetic. In order to increase the stress of doing the math task, the researchers urged the participants to hurry up or informed them they were wrong even when they gave the right answer. At rest, men and women showed little difference in heart rate, blood pressure and heart blood flow. During the math task, all the participants had increases in heart rate and blood pressure. Heart blood flow also increased in men during the stressful task, but did not change in women. The study was slated for Tuesday presentation at the Experimental Biology meeting, in San Diego. The findings suggest that women may be more susceptible to heart problems while under stress and could explain why women tend to have more heart troubles after stressful events, such as losing a spouse, study leader Chester Ray said. The results also underscore how mental stress can affect health. “Stress reduction is important for anyone, regardless of gender, but this study shines a light on how stress differently affects the hearts of women, potentially putting them at greater risk of a coronary event,” Ray said in an American Physiological Society news release. He added that further research on the mechanism behind this difference between women and men could someday lead to more targeted treatments and prevention efforts for women at risk of coronary artery disease. Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Mentalni stres doslovce može slomiti žensko srce, tvrde američki znanstvenici čije istraživanje upućuje na to da će žene izložene stresu vjerojatnije i češće patiti od koronarnih problema nego muškarci Novo istraživanje objašnjava zašto žene imaju veću vjerojatnost da obole od koronarnih simptoma nakon emocionalnog šoka poput gubitka supružnika, piše Mail Online I na protok krvi kroz srce utvrdila je kako se kod žena, za razliku od muškarca, povećaju promjene prilikom stresa. Protok krvi, tlak i otkucaji srca mjereni su kod 17 zdravih muškaraca i žena. Pod stresom je kod svih zabilježeno povećanje otkucaja srca i krvnog tlaka, bez obzira na spol. Međutim, dok su muškarci pokazali povećanje srčanog protoka krvi pod stresom, kod žena nije uočena takva promjena. 'Upravo je ova razlika potencijalni uzrok srčanih problema kod žena pod stresom', kazao je voditelj istraživanja dr. Chester Ray s Medicinskog fakulteta sveučilišta Penn State. Rezultati su iznenadili i njegov tim budući da su prethodne studije pokazale da muškarci imaju znatno manji protok krvi kroz srce nego žene za vrijeme fizičkog stresa, ali mogu objasniti zašto žene češće pate od srčanih problema nakon stresnog događaja, poput gubitka supružnika. 'Smanjenje stresa važno je za svakoga, bez obzira na spol, ali ova studija ukazuje na to kako stres utječe na srce žena budući da ih potencijalno stavlja u veći rizik od koronarnih problema.'
