Psychological features of takotsubo cardiomyopathy: report of four cases

Takotsubo or stress-induced cardiomyopathy is a cardiomyopathy in which the patient has a sudden onset, reversible left ventricular systolic dysfunction without any significant coronary artery disease. Four women, who were at a mean age of 64 years and suffered from chest pain exacerbated by emotional stress, were admitted as cases of acute coronary syndrome and were completely evaluated through precise history taking, physical examination, and ECG. Coronary angiography or coronary multidetector computed tomography was used to exclude significant coronary artery disease. In these patients with confirmed Takotsubo cardiomyopathy, in addition to the Diagnostic and Statistical Manual of the American Psychiatric Association [DSM-IV] criteria, a 71-item form of the Minnesota Multiphasic Personality Inventory [MMPI]-Mini-Mult-was employed for psychological assessment. The main common elevated scale was hypochondriasis. Individuals with high scores on this scale are obsessed with themselves, especially in regard to their body, and often use their disease symptoms in order to manipulate others. They are mainly passive aggressive, critical, and demanding, which stems from their lack of effective verbal abilities as a means of communication, specifically when it comes to anger or hostility expression. To the best of our knowledge, there is no available study evaluating patients with Takotsubo cardiomyopathy using the Mini-Mult questionnaire for psychological assessment

Correlation between plasma adiponectin levels and the presence and severity of coronary artery disease

The existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease [CAD]. However, the results of the studies conducted hitherto on this subject are inconsistent. We sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of CAD in patients undergoing non-urgent coronary angiography. In 399 consecutive patients undergoing non-urgent coronary angiography for CAD survey, plasma adiponectin, triglyceride, total cholesterol, high-density lipoprotein and low-density lipoprotein cholesterol, and fasting blood sugar levels were measured and demographic characteristics such as age, sex, Body Mass Index, diabetes mellitus history, systemic hypertension history, and family history of CAD were collected. According to the angiography results, the patients were divided into two groups of CAD and non-CAD. The severity of coronary atherosclerosis in the CAD group was defined using the Gensini score system. Average age was 61.4 +/- 9.94 years in the CAD group and 57.9 +/- 10.75 years in the non-CAD group. Also, 73.7% of the CAD group and 55.4% of the non-CAD group were male. Totally, 278 [69.7%] patients were found to have CAD. Patients without CAD did not have higher mean plasma adiponectin concentrations than did those with CAD [13.38 +/- 11.96 vs. 14.95 +/- 14.11 mcg/ml; p value = 0. 896]. After adjustment for CAD conventional risk factors, plasma adiponectin levels still were not associated with CAD. No association was found between plasma adiponectin levels and the Gensini score. Furthermore, in contrast to the fairly strong correlation previously reported, there was no correlation between adiponectin levels and conventional CAD risk factors. We could not observe any relationship between plasma adiponectin concentrations and the presence or severity of CAD in patients undergoing coronary angiography

Recurrence of Takotsubo cardiomyopathy: role of multi-detector computed tomography coronary angiography

Takotsubo cardiomyopathy [TCM], also known as stress-induced cardiomyopathy, is a clinical syndrome of transient left ventricular [LV] apical wall motion abnormality with relative preservation of the basal heart segments in the absence of any significant atherosclerosis. Recurrence of this condition is rare. We report a postmenopausal woman, who experienced two episodes of TCM within 4 months following emotional and physical stress. In the first episode, she was admitted due to severe dyspnea, accompanied by sudden-onset, prolonged, burning chest pain and palpitation. Transthoracic echocardiography revealed akinesia of the LV, with the exception of the basal regions. Coronary angiography demonstrated no significant coronary artery disease, and follow-up echocardiography showed normalization of the LV wall motion abnormalities. In the second episode, she experienced similar symptoms and echocardiography revealed similar changes. Multi-detector computed tomography revealed normal coronary arteries. After 9 days, she was discharged in good condition; and at 3 months' follow-up, she was symptom-free with normal echocardiography

Late diagnosis of large left ventricular pseudoaneurysm after mitral valve replacement and coronary artery bypass surgery by real-time three-dimensional echocardiography

One of the most serious complications of mitral valve replacement is left ventricular rupture and pseudoaneurysm formation, which is rare but potentially lethal. We herein present a late type of post mitral valve replacement and coronary artery bypass surgery pseudoaneurysm in a 74-year-old female, who was admitted to our hospital with a recent history of exertional dyspnea. She had the above-mentioned operation 10 months before. The diagnosis was made via two-dimensional and real-time three-dimensional transthoracic echocardiography. The prosthetic mitral valve was removed, and the large orifice of the pseudoaneurysm was closed by surgery. At one year's follow-up, the patient was in good condition

Prosthetic valve endocarditis: early outcome following medical or surgical treatment

Prosthetic valve endocarditis [PVE] is an important cause of morbidity and mortality associated with heart valve replacement surgery. The aim of the present study was to describe the early outcome of treatment in patients with PVE in a single center. The data of all the episodes of PVE registered at our institution between 2002 and 2007 were collected and analyzed retrospectively. The patients were assessed using clinical criteria defined by Durack and colleagues [Duke criteria]. The analysis included a detailed study of hospital records. The continuous variables were expressed as mean +/- standard deviation, and the discrete variables were presented as percentages. Thirteen patients with PVE were diagnosed and treated at our center during the study period. In all the cases, mechanical prostheses were utilized. The patients' mean age was 46.9 +/- 12.8 years. Women made up 53.8% of all the cases. Early PVE was detected in 6 [46.2%] patients, and late PVE occurred in 7 [53.8%]. Eleven [84.6%] patients were treated with intravenous antimicrobial therapy, and the other two [15.4%] required surgical removal and replacement of the infected prosthesis in addition to antibiotic therapy. Blood cultures became positive in 46.2% of the patients. Mortality rate was 15.4% [2 patients]. It seems that in selected cases with PVE, i.e. in those who remain clinically stable and respond well to antimicrobial therapy, a cure could be achieved by antimicrobial treatment alone with acceptable morbidity and mortality risk
