Emotional stress key factor for heart attacks in women: Study

The results showed that emotional stress, which occurs in about half of the patients (49%), is one of the leading causes of heart attack in women before SCAD.

 

According to the researchers, the emotional stress triggers “spontaneous dissection of the coronary artery” (SCAD), a condition that causes about one-third of heart attacks in women under 60 years.

 

SCAD occurs when the wall of an artery supplying blood to the heart is detached from the outer layer of the artery. Blood infiltrates the space between layers and forms a clot that narrows the artery and limits blood flow.

 

Symptoms are similar to a heart attack and chest pain, rapid heartbeat, pain in the arms, shoulders or jaw, discomfort, difficulty breathing, sweating and dizziness.

 

The results showed that emotional stress, which occurs in about half of the patients (49%), is one of the leading causes of heart attack in women before SCAD.

 

While 30% of cases predisposed to physical exertion (10% in this over 23 kg raised) before SCAD, the most common condition was fibromuscular dysplasia (40%), which causes abnormal development of cells in the arteries and can cause narrowing (stenosis), or aneurysms Cause tears (dissections).

 

“Emotional stress seems to be an important trigger for the Scientific Commission on Fibromuscular Dysplasia, which is more prevalent in women than in men when he played an important role. We often have no symptoms, but some patients called headaches or tinnitus called pulsatile tinnitus, “said senior researcher Jacqueline Saw, a professor at the University of British Columbia in Vancouver, Canada.

 

Other predisposing conditions were five or more pregnancies, peripartum, fertility treatment, systemic inflammatory conditions and connective tissue disease.

 

For the study, the team studied 750 patients aged 52 years with SCAD in 20 centers in Canada and two centers in the U.S. possibly between 2014 and 2018. The main symptom was chest pain in nine out of ten patients.

 

In angiography, the left anterior descending artery was most commonly affected (52 percent) and a long diffuse narrowing was the most common characteristic (a type called SCAD 2, 58 percent).

 

The results were presented at the ESC 2018 Congress, the annual conference of the European Society of Cardiology in Munich.
