Increased Incidence of Transient Left Ventricular Apical Ballooning (So-Called Takotsubo' Cardiomyopathy) After the Mid-Niigata Prefecture Earthquake

On October 23, 2004, a major earthquake, which registered 6.8 on the Richter scale, occurred in Niigata Prefecture in Japan. Emotional stress is important as a trigger of transient left ventricular apical ballooning (so-called 'Takotsubo' cardiomyopathy), but its incidence and clinical profile immediately after a natural disaster have not been fully elucidated. 'Takotsubo' cardiomyopathy was diagnosed in 16 patients (1 man, 15 women, mean age 71.5 years) within 1 month after the earthquake. Of them, 13 (81%) lived in areas where the Japan Meteorological Agency seismic intensity scale registered 6 or above, and 11 (69%) developed symptoms on the day of the earthquake. The incidence of 'Takotsubo' cardiomyopathy 1 month after the earthquake was approximately 24-fold higher near the epicenter than that before the earthquake. 'Takotsubo' cardiomyopathy can occur on the day of the earthquake in elderly women living near the epicenter.

Left ventricular apical ballooning: not an uncommon variant of acute myocardial infarction in women.

Left ventricular apical ballooning, a new syndrome recently described in Japan, is characterized by chest pain, electrocardiographic changes mimicking acute myocardial infarction, and transient apical dyskinesia with normal coronary arteries. Although several studies have defined the clinical characteristics, the prevalence of this syndrome remains unclear. This study sought to determine the prevalence of left ventricular apical ballooning syndrome. From January 2002 to September 2004, clinical, echocardiographic, and angiographic data of hospitalization and follow-up were collected from 638 consecutive patients referred to our Heart Institute for primary percutaneous intervention. Thirteen patients (2%) were diagnosed with transient left ventricular apical ballooning. All but one patient were women, representing a 6% incidence for the female patients with acute myocardial infarction. A triggering factor was identified in eight. One patient died of cardiogenic shock. Left ventricular systolic function recovered completely within 4-5 weeks in the remaining 12 survivors. This syndrome is not uncommon and should be considered particularly in female patients presenting with acute myocardial infarction.

Clinical Characteristics, Demographics and Prognosis of Transient Left Ventricular Apical Ballooning Syndrome

Transient left ventricular apical ballooning syndrome also called Tako-Tsubo cardiomyopathy is defined as a syndrome consisting of stress induced apical ballooning of the left ventricle and normal coronary arteries. The majority of the published reports are case reports or case series with a small number of patients. The goal of this study was to perform statistical analysis of reported cases and case series in the literature in order to study demographic, clinical characteristics and prognosis of this syndrome. A PubMed search of the terms transient left ventricular apical ballooning, Tako-Tsubo, takotsubo, and apical cardiomyopathy was conducted for this study. All reports that contained information about individual patients were included in the statistical analysis. The majority of the patients were women (93.5%). Asians were the largest group (57.2%) followed by Caucasians (40%). The presentations mimics an acute myocardial infarction. The most frequent presenting symptom was chest pain (65.9%) followed by dyspnea (16.2%). ST elevation was the most common ECG abnormality (87.5%). Contrary to most reports, this is not a benign disease with complications occurring in 18.9% and death in 3.2%. The most common complication was shock followed by left ventricular thrombus formation and congestive heart failure. Apical ballooning syndrome occurs most commonly in women and is associated with high complication rate. There are significant differences in presenting symptoms between race and gender which warrant further investigation.

Transient left ventricular apical ballooning in a community hospital in Germany

Introduction Tako-tsubo cardiomyopathy represents an intermittent left ventricular dysfunction with a ballooning of the left ventricular apical myocardium without significant coronary artery disease. Precise epidemiological data are not yet available. Methods and results We retrospectively reviewed 16,989 cases with diagnostic angiographies in our catheter laboratory from January 2001 until December 2004 for intermittent left ventricular apical ballooning. Thirty-two (0.2%) patients were included (50% of all cases presented in 2004, 50% of all cases during the summer months). Twenty-nine (91%) were female, median age was 67.5 years. Fourteen patients (44%) were known to have chronic obstructive pulmonary disease or asthma. Thirteen patients (41%) reported an acute stressful event prior to onset of symptoms. Twenty-five (78%) of the patients presented with clinical signs of an acute coronary syndrome with positive troponin T in 20 (63%) patients. Median left ventricular ejection fraction was 42.5%. Follow-up data of 30 patients (94%) could be obtained; median follow-up time is 6 months. Two patients died during follow-up (malignancy; unknown cause). Echocardiography was performed in 26 (81%) patients; median ejection fraction was 70%. Conclusion Tako-tsubo-like cardiomyopathy might be considered a differential diagnosis for acute coronary syndrome especially in elderly women. Chronic pulmonary diseases may be associated with a higher risk. The reason for the increasing number of cases during the last year is not clear; however, the tendency for early angiography in acute coronary syndrome may have contributed. The reason for the accumulation of cases during the summer months is also not yet understood.

META-ANAYLSIS OF TRANSIENT LEFT VENTRICULAR APICAL BALLOONING SYNDROME BASED ON GENDER AND RACE

PURPOSE: Transient Left Ventricular Apical Ballooning (LVAB) was first described in Japan in the early 1990's. Since then it has been reported in many countries worldwide. It typically presents after physical or emotional stress with chest pain, ECG changes, positive cardiac markers and marked akinesia of mid to apical left ventricular wall with ballooning appearance despite normal coronaries. The goal of this study was to perform meta-analysis of the published cases in regards to race and gender.

Assessment of Takotsubo cardiomyopathy (transient left ventricular apical ballooning) using99mTc-tetrofosmin,123I-BMIPP,123I-MIBG and99mTc-PYP myocardial SPECT

We compared Takotsubo cardiomyopathy (transient left ventricular apical ballooning) with acute myocardial infarction (AMI) using two-dimensional echocardiography, 99mTc-tetrofosmin, 99mTc-PYP, 123I-BMIPP and 123I-MIBG myocardial SPECT. We examined 7 patients with Takotsubo cardiomyopathy and 7 with AMI at the time of emergency admission (acute phase), and 2-14 days (subacute phase), one month (chronic phase), and 3 months (chronic II phase) after the attack. The left ventricle was divided into nine regions on echocardiograms and SPECT images, and the degree of abnormalities in each region was scored according to five grades from normal (0) to severely abnormal (4). Coronary angiography showed the absence of stenotic regions in patients with Takotsubo cardiomyopathy, and severely stenotic and/or occlusive lesions in patients with AMI. The total ST segment elevation on electrocardiograms (mm) was 7.8 +/- 3.7 in those with Takotsubo cardiomyopathy, and 7.3 +/- 3.9 in patients with AMI. Abnormal wall motion scores on echocardiograms were 14.2 +/- 4.6, 4.7 +/- 4.0, 1.7 +/- 2.0 and 0.5 +/- 0.4 during the acute, subacute, chronic and chronic II phases, respectively, in patients with Takotsubo cardiomyopathy, and 14.0 +/- 4.3, 11.4 +/- 3.9, 8.8 +/- 3.6 and 5.2 +/- 4.8 in those with AMI. Abnormal myocardial perfusion scores on 99mTc-tetrofosmin images were 11.8 +/- 3.5, 3.2 +/- 3.0, 0.5 +/- 1.2 and 0.2 +/- 0.4 during the acute, subacute, chronic and chronic II phases, in patients with Takotsubo cardiomyopathy, and 16.2 +/- 4.3, 13.9 +/- 4.6, 7.9 +/- 4.6 and 5.0 +/- 4.5, respectively, in those with AMI. Abnormal myocardial fatty acid scores on 123I-BMIPP images were 12.6 +/- 3.7, 6.8 +/- 3.2 and 0.4 +/- 0.6 during the subacute, chronic and chronic II phases, respectively, in patients with Takotsubo cardiomyopathy, and 16.5 +/- 5.1, 14.7 +/- 4.8 and 7.5 +/- 4.5 in those with AMI. Abnormal myocardial sympathetic nerve function scores on 123I-MIBG images were 14.8 +/- 4.0, 8.8 +/- 4.0 and 0.4 +/- 0.6 during the subacute, chronic, chronic II phases, respectively, in patients with Takotsubo cardiomyopathy, and 18.6 +/- 6.5, 16.8 +/- 6.8 and 12.9 +/- 5.2 in those with AMI. Myocardial 99mTc-PYP uptake was abnormal not only in patients with AMI but also in those with Takotsubo cardiomyopathy during the acute phase. Takotsubo cardiomyopathy might represent a stunned myocardium caused by a disturbance of the coronary microcirculation.

Tako Tsubo Cardiomyopathy (Transient Left Ventricular Apical Ballooning): Case Report of a Myocardial Perfusion Echocardiogram Study

We are reporting a case of Tako tsubo cardiomyopathy (transient left ventricular apical ballooning) in the Western population identified by a perfusion echocardiogram that demonstrated perfusion defect at baseline in the apical and adjacent walls that was incongruous to the wall-motion abnormality. The perfusion defect improved within 72 hours on a repeated study indicating that microvasculature disruption is a key feature of this enigmatic cardiomyopathy.

Takotsubo-shaped cardiomyopathy with type I CD36 deficiency

A transient left ventricular apical ballooning (so-called "ampulla" or "Takotsubo-shaped" cardiomyopathy) with type I CD36 deficiency is described in a 71-year-old woman. The patient was referred because of chest pain and worsening of dyspnea. Electrocardiogram showed T-wave inversions on the precordal leads, and acute coronary syndrome was suspected. Left ventricular apical ballooning was observed by echocardiogram and left ventriculography, and coronary arteriography did not reveal any significant stenosis. Left ventricular motion normalized at the follow-up period and there were no increases in specific markers for myocardial damage, such as myocardial band fraction of creatine kinase and troponin T, through out the admission. 123I-metaiodobengylguanidine myocardial single photon emission computed tomography (SPECT) revealed decreased accumulation areas at the apex, while 201Tl SPECT showed normal accumulation. An abnormal metabolism of cardiac free fatty acid was suggested by lack of accumulation of 123I beta-methyliodophenyl pentadecanoic acid (BMIPP) SPECT. No CD36 expression in either platelets or monocytes/macrophages was shown using flow cytometer analysis and type I CD36 deficiency was diagnosed. DNA sequencing showed that the patient had compound heterozygosity of the CD36 gene (a nucleotide change in C478T and an adenine insertion at nucleotide 1159 in exon 10). Although CD36 deficiency is thought to be involved with many cardiovascular disease and metabolic abnormalities, Takotsubo-shaped cardiomyopathy with CD36 deficiency had not been reported. Further studies of Takotsubo-shaped cardiomyopathy and CD36 deficiency may reveal an association between this cardiomyopathy and specific genetic profiles.

Ibanez and colleagues report that intravascular ultrasonography detected plaque rupture in the left anterior descending coronary arteries of 5 patients presenting with transient left ventricular apical ballooning (1). These patients had coronary arteries that appeared normal on angiography and a large recurrent distal segment of the left anterior descending coronary artery. These findings are interesting but seem an unlikely pathophysiologic explanation for most cases of transient left ventricular apical ballooning. First, angiographically detectable intracoronary thrombus in the left anterior descending coronary artery would be expected more ...

Left Ventricular Free Wall Rupture in Transient Left Ventricular Apical Ballooning

A 79-year-old woman presented with chest pain. Her symptoms, combined with the results of an electrocardiogram, echocardiogram and laboratory investigations were compatible with an extensive acute anterior myocardial infarction. However, emergency coronary angiography showed no stenotic lesion in any coronary artery, but left ventriculography revealed apical ballooning akinesis and basal hyperkinesis and she was diagnosed as having transient left ventricular apical ballooning. After 7 days, she suddenly went into cardiopulmonary arrest because of cardiac tamponade. The autopsy revealed a free wall rupture. Generally, the prognosis in transient left ventricular apical ballooning is good; left ventricular free wall rupture is very rare.

Transient Left Ventricular Apical Ballooning

The magnetic resonance imaging characteristics of transient left ventricular apical ballooning are described in this report, and the features that distinguish it from acute myocardial infarction are emphasized.

Transient Ventricular Dysfunction After Emotional Stress

We describe a patient who developed severe ventricular dysfunction and cardiogenic shock after intense emotional stress. Her subsequent course was favorable, with complete recovery of left ventricular systolic function. The coronary arteries were normal and no specific etiologic agent was demonstrated. Her clinical picture was compatible with transient left ventricular apical ballooning. [I123]metaiodobenzyl guanidine cardiac scintigraphy showed a marked decrease in cardiac sympathetic nerve activity. We discuss the pathophysiologic mechanisms of this syndrome.

Transient cerebral ischemic attack induced by transient left ventricular apical ballooning

A 57-year-old woman had transient right hemiplegia 2 days after physical stress. An electrocardiogram exhibited T-wave inversion with QT prolongation. An echocardiogram revealed akinesia of the entire left ventricle except for the basal region. Cranial computed tomography and transthoracic echocardiography revealed an apical thrombus that disappeared 1 month later. Coronary angiography was normal. After 3 months, left ventricular wall motion had completely normalized.

Tako-Tsubo Transient Left Ventricular Apical Ballooning Is Associated With a Left Anterior Descendig Coronary Artery With a Long Course Along the Apical Diaphragmatic Surface of the Left Ventricle

Introduction and objectives Tako-tsubo-like transient left ventricular apical ballooning has been described in Japan, but few cases have been reported in Western countries. We report one of the first series outside Japan, which provides new information on the coronary anatomy of this disorder. Patients and Methods From January 1998 to February 2003 we observed 11 patients with a clinical suspicion of acute myocardial infarction, normal coronary arteries, and transient tako-tsubo-like systolic left ventricular apical ballooning. We compared the coronary artery anatomy in these 11 patients with that in 44 controls matched for age and sex: 22 with normal coronary arteries and 22 with acute myocardial infarction related with an obstructive thrombus in the left anterior descending coronary artery. Results As in Japanese patients, tako-tsubo syndrome in Caucasian patients frequently occurs in women in their seventh or eighth decades of life, and is usually preceded by emotional or physical stress. The left anterior descending in our patients with tako-tsubo syndrome was longer overall, and its recurrent diaphragmatic segment was longer, than in controls. To compare these groups we designed a measure termed recurrent segment index (left anterior descending recurrent segment length/total left anterior descending length x 100). In tako-tsubo syndrome this index was 22.3 (1.5)%, vs 10.9 (6.7)% in normal controls (P Conclusions All our patients with tako-tsubo syndrome had a left anterior descending with a long recurrent segment. The identical ventriculographic findings in patients with tako-tsubo syndrome and those with acute myocardial infarction with a long recurrent segment may be due to a common etiology.

Transient Left Ventricular Apical Ballooning in a Patient With Bicuspid Aortic Valve Created a Left Ventricular Thrombus Leading to Acute Renal Infarction

A 44-year-old woman had tako-tsubo-like ventricular dysfunction with chest pain and ST segment elevation on the ECG. Echocardiography revealed a bicuspid aortic valve with moderate to severe aortic regurgitation. She developed mild heart failure during the clinical course, but the medication (furosemide, enalapril, and asprin) had to be stopped because of skin eruptions. Four weeks after ceasing the antiplatelet agent, she was re-admitted with acute renal infarction. Enhanced chest computed tomography revealed a filling defect in the left ventricle and echocardiography showed a high echogenic mass in the left ventricular apical wall. These findings strongly suggested that the renal infarction was caused by an embolism derived from a left ventricular thrombus that formed during the clinical course of the transient left ventricular apical ballooning. Anticoagulation therapy with urokinase and warfarin successfully lysed the thrombus. Left ventricular thrombus should be considered a complication of transient left ventricular apical ballooning, especially in patients with organic heart disease.

Asociación del síndrome tako-tsubo con la arteria coronaria descendente anterior con extensa distribución por el segmento diafragmático

Tako-tsubo-like transient left ventricular apical ballooning has been described in Japan, but few cases have been reported in Western countries. We report one of the first series outside Japan, which provides new information on the coronary anatomy of this disorder. From January 1998 to February 2003 we observed 11 patients with a clinical suspicion of acute myocardial infarction, normal coronary arteries, and transient tako-tsubo-like systolic left ventricular apical ballooning. We compared the coronary artery anatomy in these 11 patients with that in 44 controls matched for age and sex: 22 with normal coronary arteries and 22 with acute myocardial infarction related with an obstructive thrombus in the left anterior descending coronary artery. As in Japanese patients, tako-tsubo syndrome in Caucasian patients frequently occurs in women in their seventh or eighth decades of life, and is usually preceded by emotional or physical stress. The left anterior descending in our patients with tako-tsubo syndrome was longer overall, and its recurrent diaphragmatic segment was longer, than in controls. To compare these groups we designed a measure termed recurrent segment index (left anterior descending recurrent segment length/total left anterior descending length x 100). In tako-tsubo syndrome this index was 22.3 (1.5)%, vs 10.9 (6.7)% in normal controls (P<.001), and 11.3 (7.7)% in acute myocardial infarction patients (P<.001). Patients with acute myocardial infarction and a high recurrent segment index (> or =16%) had ventriculographic findings of systolic apical ballooning identical to those in patients with tako-tsubo syndrome. All our patients with tako-tsubo syndrome had a left anterior descending with a long recurrent segment. The identical ventriculographic findings in patients with tako-tsubo syndrome and those with acute myocardial infarction with a long recurrent segment may be due to a common etiology.

Assessment of clinical features in transient left ventricular apical ballooning

ObjectivesWe sought to assess the clinical features of transient left ventricular (LV) apical ballooning. BackgroundAlthough several cases regarding transient LV apical ballooning have been reported, the etiology remains unknown. MethodsWe investigated 17 patients (14 women, median age 74 years old with a range of 54 to 91 years old) who fulfilled the following criteria: 1) transient LV apical ballooning; 2) ST-T segment change in several leads in electrocardiogram; and 3) no history of old myocardial infarction, valvular heart disease, subarachnoid hemorrhage, or pheochromocytoma. ResultsEmotional and physical stress were observed in 16 patients (94%). Technetium-99m tetrofosmin tomographic imaging revealed decreased uptake at the apex of the left ventricle in 11 patients (85%) that later returned to uniform. No significant stenosis or angiographical slow flow in epicardial coronary arteries was observed (n = 9). Provocative focal vasospasm was induced in only one patient (14%) (n = 7). Moreover, no significant abnormality in the coronary microcirculation was detected by Doppler guidewire (n = 3) or contrast echocardiography (n = 1). No patients showed a rise in viral antibody titers. Biopsy specimens revealed interstitial fibrosis in six patients (100%) and slight cell infiltration in three others (50%) (n = 6). ConclusionsThese findings suggested that neither abnormalities in the coronary circulation nor acute myocarditis was related to the etiology. Although neurogenic stunned myocardium induced by emotional or physical stress was suggested as the etiology, further investigations are necessary.

Emotional stress induces transient left ventricular hypocontraction in the rat via activation of cardiac adrenoceptors: a possible animal model of 'tako-tsubo' cardiomyopathy.

The etiology of a novel cardiac syndrome 'tako-tsubo' cardiomyopathy, otherwise known as 'transient left ventricular (LV) apical ballooning' and which mimics acute myocardial infarction, is not clear; however, emotional or physical stress is known to precede the attack. Left ventriculography of rats experiencing emotional stress induced reversible LV apical ballooning, which was normalized by pretreatment with adrenoceptor blockade. Together with results of previous studies, activation of cardiac adrenoceptors in the absence of ischemia-reperfusion is proposed as the primary cause of this syndrome.
