Researchers discover drug that can mend the physical damage of a broken heart

by Chris Melore

MELBOURNE, Australia — From someone experiencing chest pain after a breakup, to a married couple dying within minutes of each other, there are many real examples of what doctors call broken heart syndrome. While the emotional scars are a separate issue, there may finally be a way to prevent lasting physical injury. Researchers in Australia say, for the first time, scientists have uncovered a drug that can literally mend a broken heart.

A team from Monash University find Suberanilohydroxamic acid (SAHA) can significantly improve cardiac health due to this condition. In their study, researchers used SAHA to target genes affected by a “broken heart” — or Takotsubo cardiomyopathy.

Although many may think broken heart syndrome is just a saying, doctors know it to be a very real ailment. Patients suffer a weakening of the left ventricle, the heart’s main pumping chamber. Stressful emotional triggers, usually following a traumatic event like the death of a loved one, often cause this problem. Researchers add broken heart syndrome can mimic a heart attack, causing chest pain, shortness of breath, and an irregular heartbeat.

How does SAHA heal the heart?

Suberanilohydroxamic acid is currently serving as a cancer treatment, with the U.S. Food and Drug Administration approving its use. The drug works on the heart by protecting certain genes and the acetylation/deacetylation (Ac/Dc) index in particular. This is a vitally important process which regulates gene expression in humans.

“We show for the first time a drug that shows preventative and therapeutic benefit is important to a healthy heart. The drug not only slows cardiac injury, but also reverses, the damage caused to the stressed heart,” says study leader Professor Sam El-Osta from Monash Central Clinical School in a university release.

Mostly women suffer from this mysterious condition

The study finds, in western nations, broken heart syndrome almost exclusively affects women, especially after menopause. In fact, researchers say up to eight percent of women believed to be having a heart attack may actually be dealing with Takotsubo cardiomyopathy.

While the symptoms are similar, the exact cause of the physical pain of a broken heart is still a mystery. Doctors believe a surge of stress hormones flood the heart during a traumatic event. This may cause changes in the heart muscles and blood vessels which prevent the left ventricle from working properly. The result is the heavy, achy feeling people get in the chest that can be mistaken for a heart attack.

The good news is most people recover from broken heart syndrome within two months. The bad news, unfortunately, is that some patients may suffer from heart failure due to their extreme trauma. Although death from a broken heart is rare, researchers say 20 percent of patients experience some degree of heart failure. Until now, there has been no standard treatment to alleviate this condition.

“This pre-clinical study describes a new standard in preventative and therapeutic potential using a cardioprotective drug that targets genes in the heart,” Professor El-Osta concludes.

“The team is committed to the research of women’s health recognizing the uneven sex prevalence of almost 9:1 (female to male). Based on these promising results we are focused on the continued development of compounds like SAHA to improve cardiac benefit and healthier life.”
