The Term “Takotsubo”[3]
Japanese term meaning “octopus pot”
First described in 1990 by Japanese MDs correlating the heart shape to a fisherman’s tako-tsubo

Etiology and Pathophysiology[1-
9]
The true cause of TTC is still under study but some proposed factors include…
Coronary spasm Emboli with spontaneous fibrinolysis Myocarditis Stunning after/during stressful event Abnormal response (increase) in
catecholamines such as epinephrine/norepinephrine

Diagnostic Measures
Echocardiography Contrast ventriculography CMRI (Cardiac MRI) To distinguish the difference
between TTC and AMI, a coronary angiography (CAG) is usually performed [8]
![Page 11: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/11.jpg)
Mayo Clinic Criteria for Dx of TTC [3,5]
1. Transient akinesis or dyskinesis of the left ventricular apical and mid-ventricular segments w/ regional wall-motion abnormalities extending beyond a single epicardial vascular distribution
2. Absence of obstructive coronary disease or angiographic evidence of acute plaque rupture
3. New electrocardiographic abnormalities (either ST-segment elevation or T-wave inversion)
![Page 12: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/12.jpg)
Mayo Clinic TTC Dx cont’d
ABSENCE OF:Recent significant head traumaIntracranial bleedingPheochromocytomaObstructive epicardial coronary artery
diseaseMyocarditisHypertrophic cardiomyopathy

Exclusions made before TTC Dx
Coronary Artery disease (especially proximal L main or L anterior coronary artery stenosis)
Acute coronary syndrome Acute myocardial infarction Myocarditis, Pericarditis, Aortic
dissections

Takotsubo vs. Acute Anterior MI[8]
Can be distinguished by CAG 12 Lead ECG study performed to see if
other differences can be picked up between the two. 3 main results found in TTC vs. AMI were…-1. greater ST segment elevation in leads V4-6
-2. absence of reciprocal changes in the inferior leads-3. absence of abnormal Q waves
![Page 15: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/15.jpg)
Prognosis[1,2,310]
The prognosis of patients with TTC is generally favorable; however, fatal complications have been reported with TTC such as left ventricular free wall rupture.
Patients generally recover in a couple of days to a few weeks with excellent outcomes.
Heart failure, with or without pulmonary edema, is the most common clinical complication. We believe that the published in-hospital mortality data are underestimated.
It is important to pay attention to the hemodynamics in the acute phase, which often correspond to New York Heart Association class III heart failure. Only a handful of recurrent TTC cases have been reported.
Mechanisms underlying susceptibility to recurrence are not understood. Articles are being published
![Page 16: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/16.jpg)
Prognosis Cont’d[4]
In a systematic study of multiple case reports, 14, a favorable outcome was likely. In-Hospital mortality was found in 3 of 286 patient (2 multiple organ failure, 1 ovarian cancer)
In addition, only 6 of 169 evaluated patients had a recurrence (true recurrence rate limited to the 169 out of 286)

So What does it look like?

Takotsubo “In Motion”
![Page 19: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/19.jpg)
Prevalence The prevalence of the disease is still
unknown and under study More cases are being found in women,
especially for those 60+ (one study states 75-95% of cases)
Since TCC is becoming more and more widely recognized and more specific diagnostic criteria are being established, higher prevalence rates are being reported. In 2006, a study found the U.S. presenting a 2-2.2% of TTC cases for patients admitted for STEMI or unstable angina

Treatment and Intervention
Immediate treatment involves the catheterization lab to rule out coronary obstruction disease
Mild Heart Failure-Beta blockers-ACE Inhibitors-Diuretics
Severe Heart Failure-Positive inotropic therapy-Intra-aortic balloon pump

Tx and Intervention cont’d
Stress Management-Psychiatrist, Counseling
Dietary changes Physical Therapy
Cardiac Rehab Supervised Exercise until cleared

Role of PT in Takotsubo Patients
Since Takotsubo is a cardiomyopathy, cardiac rehab should be utilized.
Easy non-stressful exercises Postural exercises to open chest
wall Breathing exercises to aide in
oxygen uptake Relaxation exercises to ease
stressors
![Page 23: Takotsubo Cardiomyopathy](https://reader036.fdocuments.us/reader036/viewer/2022062519/56815269550346895dc09b2b/html5/thumbnails/23.jpg)
Other Related Findings… In a study, African American (AA) women had
similar presenting symptoms of TTC to Non-AA women, but may differ in the electrocardiographic findings and in-hospital course of the disease. Fewer developed hypotension or needed hemodynamic support.[5]
In a case report a 37 year old woman was diagnosed with TTC after being struck by lightning. She developed an acute cardiogenic shock that put her into respiratory distress during the initial hospital assessment. Transthoracic ECG confirmed the diagnosis.[6]

Limitations in Studies
The ONE main factor affecting good validity of data in all research for TTC remains with subject numbers. Although it is growing in diagnostic criteria, the numbers are still relatively low and cohort studies are hard to design due to its rarity. [8,5]
Timing of follow-up assessments varied widely, ranging from 8-days to 4 years.[4]
