The clinical features of gender differences in takotsubo cardiomyopathy TC remain to be determined. The aim of this study was to evaluate the differences in clinical characteristics of male and female patients with TC. We obtained the clinical information of patients diagnosed with TC 84 male, female from the Tokyo CCU Network database collected from 1 January to 31 December ; the Network is comprised of 71 cardiovascular centers in the Tokyo Japan metropolitan tyoshey. We attempted to characterize clinical differences during hospitalization, comparing male and female patients with TC.

There were no significant differences in apical ballooning type, median echocardiography ejection fraction, serious ventricular arrhythmias such as ventricular tachycardia or fibrillationor cardiovascular death between male and female patients. Male sex were younger than female patients median age at hospitalization for sex patients was 72 years vs.

Prior physical stress was more common in male than female patients Cardiac complications in our dataset appeared to be more common in male than female patients with TC during their hospitalization. Further investigation is required to clarify the underlying mechanisms tyoshey for the observed gender differences.

Takotsubo cardiomyopathy TC is characterized by reversible left ventricular dysfunction with predominance in women, especially those who are postmenopausal [ 1 — 3 ]. Data from men with TC are scarce and their clinical features remains to be determined because a large clinical database is lacking. The Tokyo CCU Network database is an ongoing multicenter registry that prospectively collects information from emergency admissions to acute cardiac care facilities [ 4 — 7 ].

This database, including 71 large-volume cardiovascular centers in the Tokyo metropolitan sex, provides us a unique opportunity to characterize fundamental feature s of the disease. Using this database, our study sought to characterize gender-specific differences in hospitalized patients with TC.

Written or oral informed consent was obtained in all cases according to the protocol. Both versions of informed consent were sex by the Tokyo CCU Network Scientific Committee, as the study did not identify individual patients. Individual clinical information was recorded into the database by the Tokyo CCU Network sex of each institution, and the final sex were collected by the Tokyo CCU Network Scientific Committee under conditions of anonymity, according to the ethical guidelines on epidemiological surveys released from the Japanese Ministry of Health, Labor, and Welfare.

A total of 57, patients were admitted from 1 January to 31 December to the 71 large-volume cardiovascular centers which participated in the Tokyo CCU Network. We examined the records of patients diagnosed with TC, where detailed clinical information was obtained through a secondary questionnaire from the 58 cardiovascular centers.

We defined TC according to the following criteria proposed by the Mayo Clinic [ 8 ]:. We also collected data on therapeutic procedures during hospitalization such as cardiopulmonary supportive therapies and cardiovascular medications. We defined composite cardiac events as cardiovascular death, severe pump failure, and serious ventricular arrhythmias such as VT or VF.

Numerical factors with skewed distribution are shown as median interquartile range. The Wilcoxon rank-sum test was used to determine statistically significant differences in clinical parameters between two different groups.

Stepwise multiple logistic regression analysis was performed to predict in-hospital composite cardiac events. Patient characteristics are shown in Table 1. There were 84 male Median patient age was 76 years of age range: 67—82 yearswith tyoshey age less than female age. Hospitalization occurred for The chief complaints noted by patients were chest pain Preceding physical or emotional stresses were identified in patients Physical stress is further defined Fig 1but we could not obtain a breakdown of the individual content of emotional stress.

Vital signs, such as systolic and diastolic blood pressure, heart rate and arterial oxygen saturation were similar between genders.

Electrocardiographic findings, echocardiographic findings, and laboratory data are shown in Table 2. There were no differences between men and women in terms of electrocardiographic abnormalities. Echocardiographic findings showed that apical ballooning type was noted in patients Left ventricular thrombus was detected in 2 male patients and no female patients.

Brain natriuretic peptide BNP level on admission was also moderately increased. Emergency catheterization was performed in cases Coronary sex was performed in Provocation of coronary spasm using acetylcholine was attempted in only 13 cases 2 men, 11 womenwith a positive outcome for 1 woman and negative outcomes in the remaining 12 cases. Endomyocardial biopsy was tyoshey in 2 patients details unknown.

However, wall motion abnormalities were not accounted for by these lesions in any patients. Clinical outcome during hospitalization is shown in Fig 2. Three hundred and twenty-one patients Respiratory support was more commonly needed in male patients with than female.

Catecholamines were used in AVB was observed in 4 patients 1 male, 3 female requiring permanent pacemaker implantation in the male patient. Two male patients received implantation of cardioverter-defibrillators because of VF. Implantation of a permanent pacemaker or cardioverter-defibrillator was more common in men than women 3. Atrial fibrillation or flutter was noted in 17 male and in 32 female patients Twenty-three patients 6.

There were 7 cardiovascular deaths 1. In-hospital composite cardiac events were noted in 64 patients Table 3. This cardiac event was significantly more common in male than female patients After excluding TC patients with documented coronary artery disease, there were 73 males and female patients; however, in-hospital composite cardiac events still tended to be more common in men than women in this subset of patients with TC The present study showed that adverse clinical outcomes were more common in male than female patients with TC during hospitalization.

We confirmed that male gender was independently associated with composite cardiac events, as was the presence of higher baseline WBC levels. Previous reports showed that patients with TC were predominantly female, and the percentage of men experiencing TC ranged from 4.

The Tokyo CCU network database has revealed that It is of note that the Tokyo CCU Network database consists of patients who were tyoshey at major cardiovascular centers, and does not necessarily reflect the general population with TC. It is well known that emergency ambulance use is greater tyoshey men than women in emergency physical situations tyoshey 1617 ].

Male patients with TC may also utilize sex emergency ambulance service sooner and more frequently than females. Actually, percentage of patients who were hospitalized within 24 hours from attack was higher in male than female in the present data. In addition, we analyzed the current data on acute cardiac care in which severely ill patients who were hospitalized to cardiac care unit.

In this database, patients with non-cardiac illness who were afflicted by postsurgical stress and infection, etc seem to tyoshey excluded. These two factors may be responsible for the discrepancy in the incidence of male gender between Asian and Western countries. A number of studies have attempted to characterize gender differences in patients with TC [ 141518 ]. Among them, Brinjikji et al. They concluded that more serious comorbidities might be responsible for the higher mortality in male patients.

However, male gender was a still predictor of mortality independently from underlying critical illnesses. In the present study, overall mortality tended to be higher in male than female patients, but was not statistically different. However, composite cardiac events, such as severe pump failure, serious ventricular arrhythmias, and cardiovascular death were significantly more common in male than female patients, suggesting these potentially fatal complications might have contributed to the worse clinical outcomes in male patients.

We also found that exaggerated inflammatory response during the process of TC was associated with worse clinical outcome in male patients. In sex study, 31 of the patients who underwent cardiac catheterization had CAD. After tyoshey these TC patients with documented CAD, in-hospital composite cardiac events still tended to be more common in male than female patients. The presence of CAD in these patients did not appear to affect the gender differences noted.

The etiology of TC is not well understood, but a number of previous reports suggested a deficiency of estrogen release as one of the underlying mechanisms for the pathogenesis [ 19 — 21 ], since estrogen exerts various cardioprotective effects including inhibition of tyoshey sympathoadrenal and renin-angiotensin system activation and antioxidant effects [ 2223 ].

In ovariectomized rats, myofilament calcium sensitivity was increased in addition to up regulation of beta-adrenergic receptor density [ 2425 ]. Ueyama et al. Reduction of estrogen levels following menopause might be involved as the primary cause of TC both by indirect action on the nervous system and by tyoshey action on the heart [ 26 ].

Estrogen treatment also increases the levels of atrial natriuretic peptide and heat shock protein 70 in the heart sex 27 ]. Secretion of endogenous estrogen is lower in postmenopausal than premenopausal women, but estrogen level in postmenopausal women appears to be even lower than seen in men [ 28 ]. On the other hand, sex was reported that during acute stressful events estradiol concentrations become elevated in postmenopausal TC patients compared with an age- sex gender-matched control subjects who were afflicted by acute myocardial infarction [ 29 ].

We previously reported that the inflammatory process, as reflected by an increase in WBC, might play a role in the adverse outcomes in patients with TC [ 6 ].

Cardiovascular magnetic resonance imaging MRI showed complete recovery of left ventricular wall motion abnormality along with inflammatory findings in T2-weighted images [ 30 ]. These inflammatory processes may be associated with neurohumoral activation via noradrenaline and BNP [ 31 ]. In the present study, there was no significant difference in median WBC values between male and female patients, with a tendency to be slightly higher in men than in women.

However, WBC values were confirmed to be an independent predictor of adverse clinical outcome using stepwise multiple logistic regression analysis. There is limited evidence on how gender affects inflammatory response in cardiovascular disease. Roberts et al.

They suggested that differential expression of Toll-like receptor signaling might be at least partly responsible for the gender difference seen [ 32 ]. Differences tyoshey the gene expression profile, coupled with the cardioprotective role of estrogen may be responsible for the gender difference seen in our study. There was a difference in the prior stressors between male and female patients in the present study, although prior stressors were not identified in approximately one-third of our study patients.

Previous reports on small patient populations suggested similar findings [ 13 ], and we confirmed this issue using a larger sample size. We cannot exclude the possibility that physical stress affects clinical outcome more than mental stress, however.

Lastly, the Tokyo CCU Network database included limited data during hospitalization for cardiovascular reasons.

More careful monitoring and more intensive therapies may be required for men with TC than for women with the same condition during hospitalization.
