Clues To 'Broken Heart Syndrome'
Science Daily The causes of "broken heart syndrome" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to new data.
Researchers from Brown University in Providence, RI, have developed the largest registry of patients in the United States with Takotsubo cardiomyopathy, informally known as broken heart syndrome because it is often preceded by an emotional or physical shock of some kind and almost always strikes women. One thing is certain: Patients are usually critically ill during the first 48 hours.
"These patients can be difficult to manage for emergency physicians and cardiologists alike," said cardiology fellow Richard Regnante, M.D. "They may be in cardiac arrest, cardiogenic shock, or severe heart failure. They may require advanced life support with airway management and medications to support blood pressure."
In fact, based on symptoms, electrocardiographic (ECG) tracings, and blood tests for heart damage, it often seems as if the patient is having a heart attack. The mystery deepens in the cardiac catheterization laboratory, when the interventional cardiologist finds no blockage in the coronary arteries.
To date, the registry has enrolled 40 patients diagnosed with Takotsubo cardiomyopathy at two major hospitals in Rhode Island over a period of nearly 2½ years. Ninety-five percent were women, and 60 percent experienced some type of stress shortly before coming to the emergency room. The intensity of the stress varied dramatically, however, ranging from armed robbery to a heated argument, tooth extraction, or preparation for a colonoscopy.
"We don't know why some women develop this syndrome after what appears to be minimal stress, while other women experience severely stressful events but don't develop Takotsubo cardiomyopathy," Dr. Regnante said. A surge of stress hormones likely plays a role, he said, but it is also possible that a blood clot temporarily blocks a major artery of the heart, then dissolves before being detected during coronary angiography.
The most common symptom of broken heart syndrome was chest pain, in 70 percent of patients, followed by shortness of breath in 33 percent. All patients had ECG changes suggestive of an acute coronary syndrome, a term that encompasses both heart attack and unstable angina. Troponin-I, a blood test for heart damage, was positive in 95 percent of patients. Twenty percent of patients were unable to breathe on their own and needed a respirator. In all patients, cardiac catheterization showed characteristic abnormalities in the motion of the heart. One patient died of acute heart failure.
The good news is that most patients who survived the first 48 hours had a steady recovery. Thirty one, or 78 percent, of patients had follow-up echocardiography within a few weeks. Heart function was found to be normal in 29 of 30.
Dr. Regnante said that long-term follow-up will be critical to improved understanding of Takotsubo cardiomyopathy. In addition, he and his colleagues are gathering information on patients who have intravascular ultrasound during cardiac catheterization. This imaging test, in which a tiny ultrasound probe is threaded into the coronary arteries on the tip of a catheter, may show whether the patient has clogged arteries or unstable plaques that are not visible on coronary angiography. These findings will help guide long-term treatment.
"Because we don't yet know what causes this phenomenon, we don't know what the best long-term management should include," he said. "As we gather more information on these patients, we can start to understand who is affected by Takotsubo cardiomyopathy, offer more focused long-term care, and make predictions about their outcomes."
This data was reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9--12, 2007, in Orlando, FL.

Doctors doing this or that to solve the mystery in question may be nobel, but sorry folks, there some things the doctors can’t fix.
Does this apply to baseball fans?
If you're a Royals fan, like me, yes it does.
The causes of “broken heart syndrome” remain a mystery ... THANKS blam for this thread.
Of course it does ... especially if you are a Red Sox fan.
I’m an O’s fan - a decade of grief from Angelos.
"Cardiogenic shock typically is triggered by a heart attack, and is definitely life-threatening. Even with treatment, it ends in death 65 to 80 percent of the time. Cardiogenic shock is characterized by a decreased pumping ability of the heart that causes a shocklike state with inadequate perfusion to the tissues."
Most interesting.
It sounds like this is what happened to Bono’s mother.
I don’t know that story.
As I walk this land with broken dreams
I have visions of many things
Love’s happiness is just an illusion
Filled with sadness and confusion,
What becomes of the broken hearted
Who had love that’s now departed?
I know I’ve got to find
Some kind of peace of mind
Maybe.
The fruits of love grow all around
But for me they come a tumblin’ down.
Every day heartaches grow a little stronger
I can’t stand this pain much longer
I walk in shadows
Searching for light
Cold and alone
No comfort in sight,
Hoping and praying for someone to care
Always moving and goin to where
What becomes of the broken hearted
Who had love that’s now departed?
I know I’ve got to find
Some kind of peace of mind
Maybe.
I’m searching though I don’t succeed,
But someone look, there’s a growing need.
Oh, he is lost, there’s no place for beginning,
All that’s left is an unhappy ending.
Now what’s become of the broken-hearted
Who had love that’s now departed?
I know I’ve got to find
Some kind of peace of mind
I’ll be searching everywhere
Just to find someone to care.
I’ll be looking everyday
I know I’m gonna find a way
Nothings gonna stop me now
I’ll find a way somehow
I’ll be searching everywhere
Bono was 14 when his grandfather died (mother’s father)
Apparantly she collapsed at the cemetary during her father’s burial and was dead within 1 or 2 days.
It’s the inspiration for some great songs, especially “I Will Follow”

Anyone? Do you happen to know how I can re-set my line width? I use firefox. Thanks.
AMEN! PRAISE GOD!
Interesting. We shall see what it all will mean.
I’ll certainly say AMEN to that.
PING TO END TIMES PING LIST
I’ve read two prophetic words on attacks on 7 cities, one in Canada (Montreal) and the others in the US. I think they were NYC, Washington, Cincinnati, Chicago, possibly San Francisco and I believe in TX but am not sure. It’s been a while since I read them.
