Even though a newly recognized cardiomyopathy, which mainly impacts women, is typically treatable, Tako-tsubo cardiomyopathy can also be deadly when compounded by other co-morbidities, such as heart failure, according to a study being presented March 9 at the American College of Cardiology (ACC) Scientific Sessions.
This condition, formally known as Tako-tsubo cardiomyopathy (TTC) and informally known as stress cardiomyopathy or broken heart syndrome, has abrupt onset of symptoms and is characterized by a distinctive left ventricular (LV) contraction profile. Ninety percent of the time, this condition affects women, who are usually middle aged and older, and the condition usually is triggered by a stressful event.
"Although TTC is typically reversible and considered to have favorable clinical outcomes, we have identified an important subset of patients, particularly those with severe heart failure and hypotension, who can have a substantial mortality risk," says the study's lead author Scott W. Sharkey, MD, a research cardiologist at the Minneapolis Heart Institute Foundation and a physician at the Minneapolis Heart Institute at Abbott Northwestern Hospital in Minneapolis. "It's also important that physicians are aware this is not a rare a condition, as it is present in nearly 10 percent of women who present to the hospital with suspected heart attacks."
MHIF researchers reviewed 250 TTC patients who presented to the Minneapolis Heart Institute at Abbott Northwestern Hospital between 2001 and 2012. Then, they segregated those TTC patients presenting with particularly severe heart failure and very low pressure, or hypotension (systolic blood pressure < 100 mm Hg), who required supportive treatment.
They found that severe hypotensive heart failure occurred in 45 patients. In this subset, 9 female patients died in-hospital despite aggressive treatment intervention, representing the only TTC-related hospital deaths in the 250 pa
