Impact of a Virtual Reality-Based Simulation on Empathy and Attitudes Toward Schizophrenia.

Virtual Reality (VR) has been identified as one of the most promising resources for developing empathy towards stigmatized groups as it allows individuals to experience a situation close to reality from another person's perspective. This quasi-experimental study aimed to examine the impact on empathy, knowledge, and attitudes towards people with schizophrenia of a VR simulation that reproduces the experience of psychotic symptoms while performing a cognitive task compared with watching a 2D video and, thus, how these experiences could reduce stigma towards people diagnosed with schizophrenia. The sample comprised of 102 higher education health students, distributed by the experimental and control groups. The impact of the program was measured by completing multiple questionnaires on levels of empathy, attitudes, and mental health knowledge. Both methods (VR and 2D video) were, to a certain extent, effective. However, VR was more effective at eliciting attitudes and knowledge change compared to the control group. These findings suggest that not only VR but also 2D videos could be interesting strategies to enhance empathy and improve attitudes towards people with schizophrenia in higher education health students.

[The impact of direct access to primary angioplasty on reducing the mortality associated with anterior ST-segment elevation myocardial infarction: the experience of the Algarve region of Portugal]. / Impacto da via verde coronária e da angioplastia primária na redução da mortalidade associada ao enfarte com elevação do segmento ST anterior. A experiência algarvia.

INTRODUCTION: There are few published data on mortality in anterior ST-segment elevation myocardial infarction (STEMI) in Portugal, particularly in centers with direct access to primary angioplasty. We present the experience of a center with direct access to primary angioplasty in the management of patients admitted with anterior STEMI. METHODS: We performed a retrospective study of 120 patients admitted with anterior STEMI in 2008 to Faro Hospital (Algarve region, Portugal). RESULTS: Significant coronary artery stenosis was found in 99 patients (82.5%). These patients were predominantly male (79%), and had a mean age of 63 years. Primary angioplasty was performed in the majority of patients within 6 hours of symptom onset and median ECG-to-balloon time was 89 minutes. Primary angioplasty was successful in 98% of patients and complete revascularization was achieved in 83%. Radial access was used in 82% of cases. In-hospital and 30-day mortality was 3%. CONCLUSION: Direct access to primary angioplasty was associated with low mortality in patients admitted with anterior STEMI.

[Loeffler's endocarditis--a case report]. / Endomiocardite de Löffler--a propósito de um caso clínico.

Loeffler's endocarditis is an acute form of primary restrictive cardiomyopathy. We report the case of a young woman with pleuritic chest pain associated with fever and hypereosinophilia. She was hospitalized with suspected acute myopericarditis and was treated with aspirin, leading to clinical improvement. Ten days after discharge, she was rehospitalized due to recurrence of chest pain. The echocardiogram showed what appeared to be a mass filling the apex of the right ventricle (RV). She was referred for magnetic resonance imaging, which revealed marked myocardial thickening in the apex of the RV. The patient underwent an endomyocardial biopsy, resulting in a diagnosis of eosinophilic endocarditis. After treatment with prednisolone, all symptoms and the eosinophilia disappeared, and there was complete remission of the RV abnormalities. After three years of follow-up, the patient remains asymptomatic. This case shows that, even without an etiologic diagnosis of eosinophilia, the prognosis for Loeffler's endocarditis can be favorable if treatment is initiated early.

Implementation of a pre-hospital network favoring primary angioplasty in STEMI to reduce mortality: the Algarve Project.

OBJECTIVE: To analyze the impact of reperfusion by either primary percutaneous coronary intervention (PPCI) or fibrinolysis, and mortality rates of a pre-hospital fast-track network for treating patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: A pre-hospital network for STEMI patients, designated the Green Lane for Acute Myocardial Infarction (GL-AMI), has been implemented in the southern region of Portugal --the Algarve Project. We performed an observational study based on a prospective registry of 1338 patients admitted to Faro Hospital between 2004 and 2009, classified in two groups according to the method of admission: emergency department group (EDG) and GL-AMI group (GLG). More patients from GLG were reperfused (p < 0.0001). PPCI was the preferred method of reperfusion, 73.1% in GLG and 45.3% in EDG. Time delays were significantly shorter in GLG, except for pre-hospital delay: pre-hospital delay (p = 0.11); door-to-needle (p < 0.0001); door-to-balloon (p < 0.0001); and delay between symptoms and reperfusion (p < 0.0001). In-hospital mortality (4.3% vs 9.2%, p = 0.0007) and 6-month mortality (6.3% vs 13.8%, p < 0.0001) were significantly lower in GLG. CONCLUSIONS: The Algarve Project significantly reduced the time delay between onset of symptoms and reperfusion, significantly increased the rate of reperfusion, and significantly reduced in-hospital and six-month mortality.

Female gender: an independent factor in ST-elevation myocardial infarction.

INTRODUCTION: Cardiovascular disease is the leading cause of death in women. In ST-elevation myocardial infarction (STEMI) in particular, the question has been raised whether specific characteristics of women confer a worse prognosis. OBJECTIVE: To evaluate the differences in STEMI patients between the genders in cardiovascular risk profile, clinical presentation, therapeutic approach and in-hospital and 6-month mortality rates. METHODS: We analyzed 1578 patients admitted consecutively with STEMI during a 7-year period (from January 13, 2002 to December 31, 2008). The patients were divided into two groups according to gender, and compared in terms of baseline clinical and demographic characteristics, pre-hospital and in-hospital delay, clinical presentation on admission, reperfusion therapy, severity of coronary disease and in-hospital and 6-month mortality. RESULTS: Of the 1578 patients, 26% were female. Women were older (by 8 years), and had a higher cardiovascular risk profile. On admission, their clinical presentation was more severe, with a higher frequency of anterior myocardial infarction and acute heart failure symptoms. Women had longer ischemic times and lower rates of reperfusion therapy. Mortality in women was significantly higher than in men, both in-hospital (17.5 vs. 5.3%) and at 6 months (23.5% vs. 8.2%). After adjustment in multivariate analysis, mortality in women remained higher. CONCLUSIONS: The adverse demographic and clinical profile could partially explain the worse prognosis of STEMI in women. This, together with longer pre-hospital delays, led to underuse of reperfusion therapy. Even so, female gender by itself had a negative and independent influence on mortality in STEMI patients.

[Endomyocardial fibrosis with massive calcification of the left ventricle]. / Fibrose endomiocárdica com calcificação maciça do ventrículo esquerdo.

Endomyocardial fibrosis is a rare disease, endemic in tropical countries. It is characterized by fibrosis of the endocardium that can extend to myocardium. Important calcification of the endocardium is rare with only a few cases reported in the literature. We report a case of endomyocardial fibrosis in a european caucasian patient, associated with massive calcification of left ventricle.

A case of rare longevity of tetralogy Fallot.

Tetralogy of Fallot is one of the most common forms of cyanotic congenital heart disease. In the absence of surgical correction it has high early mortality, with most patients dying in childhood. Survival beyond the seventh decade of life is extremely rare. The authors present the case of a patient with uncorrected tetralogy of Fallot who survived to the age of eighty. The longevity of this patient is certainly linked to the association between a large ventricular septal defect and "balanced" pulmonary stenosis: sufficiently mild not to cause severe hypoxia, but significant enough to protect the pulmonary vasculature.

Unstable angina as initial manifestation of Wegener granulomatosis: case report.

Wegener granulomatosis (WG) is a necrotizing vasculitis that usually affects the respiratory tract, in association with kidney disease. Cardiac involvement is rare and silent in most cases, only becoming evident in necropsy studies. The authors report the case of a patient with WG, whose unstable angina was the first clinical manifestation, although the patient had suffered a previous unrecognized myocardial infarction. In most cases cardiovascular disease is clinically silent, but there may be symptoms indicating involvement of the coronary arteries, pericardium, myocardium, endocardium, cardiac valves, conduction system or thoracic great vessels. In most cases cardiac manifestations appear late in the natural history of GW. In the case reported, cardiac symptoms appeared as the first manifestation of the disease, a situation which we were unable to find described in the literature. The authors review the literature on cardiac manifestations of WG, together with recommendations for diagnosis and follow-up of this disease.

In-hospital delay in ST-segment-elevation myocardial infarction after Manchester Triage.

INTRODUCTION: In ST-segment elevation myocardial infarction (STEMI), time to reperfusion influences morbidity and mortality, and reducing in-hospital delay (IHD) continues to be important. Doubts have been expressed whether the Manchester Triage System (MTS) contributes to this objective. OBJECTIVE: To evaluate the effectiveness of the MTS in classifying STEMI patients and its effect on IHD. METHODS: We analyzed 278 patients with STEMI admitted to the Coronary Care Unit through the Emergency Department between January 13 2005 and November 26 2006. The patients were divided into two groups according to their MTS classification: Group A--emergent and very urgent patients; Group B--urgent and standard patients. The two groups were compared in terms of clinical and demographic characteristics, pre-hospital delay (PHD), IHD and door-to-needle (DNT) and door-to-balloon (DBT) times. RESULTS: The mean age of the patients studied was 68 +/- 14 years, and 184 patients (65.7%) were male. Group A comprised 220 patients (79%) and Group B 58 patients (21%). There were no significant differences between the two groups in clinical or demographic characteristics or in PHD. IHD, DNT and DBT were significantly longer in Group B. CONCLUSIONS: 1) Although the majority of STEMI patients were classified as emergent or very urgent, the percentage not classified as such by the MTS was excessively high. 2) This could not be explained by clinical characteristics or by PHD. 3) The incorrect classification by the MTS of patients with STEMI resulted in significantly increased IHD in a large proportion of patients, limiting prompt access to reperfusion therapy.

Apical ballooning syndrome--a review of five cases.

INTRODUCTION: Takotsubo syndrome (apical ballooning syndrome) was described for the first time in Japan, at the beginning of the 1990s. It is characterized by the acute onset of extensive but transient akinesia of the apical and mid portions of the left ventricle, in the absence of significant coronary disease. OBJECTIVE: We describe five patients who were admitted to our hospital with this new syndrome between June 2004 and December 2005. These patients represented 0.8% of a total of 613 patients admitted for acute myocardial infarction in that period. RESULTS: All the patients were female, with a mean age of 60.2+/-10.3 years. Chest pain was the most frequent clinical presentation (n=5). A possible triggering factor, intense emotional stress, was identified in two patients. At admission, the electrocardiogram showed ST elevation in two patients and Q waves in the precordial leads in one. All cases had negative T waves in the precordial leads at some point. All patients had increased troponin levels but only two had elevated cardiac enzymes. The echocardiogram revealed extensive akinesia of the apical and mid portions of the left ventricle, and a thrombus was observed in one patient. Coronary angiography showed no significant lesions. Currently, all five patients are virtually asymptomatic, with regression of left ventricular wall-motion abnormalities on echocardiography. CONCLUSION: This is the first series of apical ballooning syndrome described in Portugal. Although rare, it should be considered in the differential diagnosis of acute myocardial infarction. Despite its transient nature, in the acute phase it can be a serious condition. More research is needed to better characterize this new entity.

Evaluation of glucose metabolism profile in coronary disease. Prospective study in hospitalized patients.

BACKGROUND: In 1995, it was estimated that 4% of the adult population had a diagnosis of diabetes mellitus. The trend is for growing prevalence, with a prediction of 300 million individuals with diabetes diagnosed in 2025. There seems to be a large number of asymptomatic individuals with undiagnosed disorders of glucose metabolism. These disorders, whether diabetes mellitus or conditions considered as prediabetic, including impaired glucose tolerance or impaired fasting glucose, represent an important risk factor for coronary disease and worsen the prognosis of established disease. The aim of this study was to evaluate the prevalence of glucose metabolism disorders in individuals admitted to hospital with coronary disease and to determine whether a significant number of these patients had previously undiagnosed diabetes or prediabetic conditions. METHODS: We conducted a prospective study of 44 consecutive patients admitted to the Cardiology Department with a diagnosis of coronary disease, whether previously established or established at the time of admission. We measured morning plasma glucose in all patients, after at least eight hours fasting, and all except those with a previous diagnosis of diabetes underwent an oral glucose tolerance test with 75 g of glucose before hospital discharge. For classification of glucometabolic state, we used the values defined by the World Health Organization (1999). RESULTS: The mean age of our cohort was 64.2+/-13.6 years. The most prevalent disorder was diabetes, with 19 patients (43.2%). Of these, 12 patients (27.3%) had a previous diagnosis of diabetes and 7 patients (15.9%) were unaware that they had the disease. We identified isolated impaired glucose tolerance in 11 patients (25%), isolated impaired fasting glucose in one patient (2.3%) and combined impaired glucose tolerance and impaired fasting glucose in another (2.3%). The remaining 12 patients (27.3%) revealed normal glycemia values. CONCLUSIONS: Glucose metabolism disorders including diabetes and impaired glucose tolerance have a high prevalence in coronary patients. This population includes a significant number of asymptomatic patients with undiagnosed diabetes or undetected prediabetic conditions. A systematic evaluation of the glucometabolic state of individuals with coronary disease during hospitalization, using an oral glucose tolerance test, may enable earlier identification of these disorders and implementation of measures to reduce their future impact.

Are degenerative changes in the aortic valve an additional important marker of atherosclerosis?

BACKGROUND AND AIM: Degenerative changes of the mitral annulus are associated with atherosclerotic disease. It has recently been suggested that degenerative changes in the aortic valve may also be associated with atherosclerosis. The intima-media thickness of the carotid arteries has been used as one of the best and earliest markers of atherosclerosis. The aim of this study was to evaluate whether the additional presence of degenerative changes in the aortic valve in coronary patients with mitral annular degenerative disease reflects different degrees of intima-media thickness as assessed by carotid ultrasonography. METHODS: The study group included 55 patients admitted for myocardial infarction who presented with degenerative changes of the mitral annulus assessed by echocardiography. Exclusion criteria were moderate or severe valvular heart disease and chronic renal failure. All patients underwent echocardiography, cardiac Doppler and carotid ultrasonography. Based on the echocardiographic findings, two sub-groups were formed: 1--with degenerative changes of the aortic valve; and 2--without degenerative changes of the aortic valve. Carotid ultrasonography was performed with a 7.5-10 MHz linear transducer and the following parameters were evaluated: 1--bilateral measurement of intima-media thickness in the common carotid artery; 2-- incidence of atheromatous plaques in the carotid arteries, and 3--incidence of >50% lesion in the internal carotid arteries assessed by pulsed Doppler (Vmax >125 cm/s). RESULTS: Thirty-three patients (aged 71.6 +/- 7.1 years), 21 men and 12 women, did not present degenerative changes in the aortic valve. The other group consisted of 22 individuals (aged 72.9 +/- 6.8 years), 14 men and 8 women, who did have such changes. Differences in age and gender distribution between the two groups were not significant. Patients with degenerative aortic valve disease had greater intima-media thickness than the control group (1.6 +/- 0.3 mm versus 1.3 +/- 0.4 mm, p < 0.001). Fifteen (68%) patients with aortic degenerative disease had plaques in the carotid arteries compared to 11 (33%) patients in the control group (p < 0.05). No significant differences were found between the two groups regarding the incidence of >50% atherosclerotic lesion in the internal carotid artery (22% versus 12%; NS). CONCLUSIONS: Patients with degenerative changes in the aortic valve presented significantly greater intima-media thickness and a higher incidence of atherosclerotic plaques than the control group, suggesting that their presence may constitute an additional important marker of severity of atherosclerotic disease.
