The aim of the present study was to define the prevalence, characteristics, risk factors and impact on clinical outcomes of acute myocardial infarction (AMI) versus other cardiovascular events (CVEs) in patients with community-acquired pneumonia (CAP). This was an international, multicentre, observational, prospective study of CAP patients hospitalised in eight hospitals in Italy and Switzerland. Three groups were identified: those without CVEs, those with AMI and those with other CVEs. Among 905 patients, 21 (2.3%) patients experienced at least one AMI, while 107 (11.7%) patients experienced at least one other CVE. Patients with CAP and either AMI or other CVEs showed a higher severity of the disease than patients with CAP alone. Female sex, liver disease and the presence of severe sepsis were independent predictors for the occurrence of AMI, while female sex, age >65 years, neurological disease and the presence of pleural effusion predicted other CVEs. In-hospital mortality was significantly higher among those who experienced AMI in comparison to those experiencing other CVEs (43% versus 21%, p=0.039). The presence of AMI showed an adjusted odds ratio for in-hospital mortality of 3.57 (p=0.012) and for other CVEs of 2.63 (p=0.002). These findings on AMI versus other CVEs as complications of CAP may be important when planning interventional studies on cardioprotective medications.

A 50-year-old hypertensive smoker presented with a typical angina of 2 days duration. An urgent ECG revealed extensive anterior wall myocardial infarction. In view of the delayed presentation, the patient was conservatively managed with heparin. In-hospital echocardiogram showed akinesia of entire left anterior descending artery (LAD) territory with severe left ventricular (LV) dysfunction. He was discharged with a plan for early coronary intervention. However, he presented a fortnight later with acute pulmonary oedema. General appraisal revealed a restless individual who was dyspnoeic and diaphoretic at rest. On clinical examination, the patient was in hypotension with features of biventricular failure. A 12-lead ECG showed QS pattern with persistent ST segment elevation in precordial leads. The chest radiograph demonstrated features of pulmonary oedema, cardiomegaly and bilateral pleural effusion. Creatine Phosphokinase-MB (CPK-MB) was negative. A preliminary transthoracic echocardiography was done (figure 1 and see online supplementary video 1).

The aim of the present study was to investigate the characteristics and value of 3D dynamic contrast-enhanced magnetic resonance pulmonary angiography (3D-DCE-MRPA) for the diagnosis of pulmonary embolism (PE). Among patients suspected with PE, 30 cases were scheduled for 3D-DCE-MRPA [magnetic resonance imaging (MRI) group], and 30 cases were examined using multislice computed tomographic pulmonary angiography (msCTPA) [computed tomography (CT) group]. Direct signs including location, number, morphology of emboli, and indirect signs such as pulmonary infarction, pneumonia and pleural effusion, were analyzed. Pulmonary artery enhancement was observed. Image quality was contrasted, branches of the pulmonary artery revealed, and differences in sensitivity, specificity and signal-to-noise ratio (SNR) were compared. The number and morphology of emboli in the two groups were compared, and there were no significant differences (P>0.05). In the MRI group, significantly more emboli were located in segmental and subsegmental bronchi (P<0.05). The indirect signs in the two groups were compared and the differences were not statistically significant (P>0.05). The difference in image quality between the two groups was not statistically significant (P>0.05). Levels 5 and 6 of the pulmonary artery branch were more evident in the MRI group compared to the CT group. The SNR and carrier-to-noise ratio in the MRI group were significantly higher than those in the CT group (P<0.05). Twenty-six cases of PE were diagnosed in the CT group, with a sensitivity of 90.5% and specificity of 86.7%. Twenty-five cases were diagnosed in the MRI group, with a sensitivity of 92.3% and specificity of 84.2%. In conclusion, 3D-DCE-MRPA surpassed msCTPA in revealing segmental and subsegmental pulmonary artery PE.

Left ventricular pseudoaneurysm is a rare complication of acute myocardial infarction, associated with high mortality. However, it can present in a non-specific manner, complicating and delaying the diagnosis. The authors present the case of a 65-year-old patient, hypertensive, with no other known relevant medical history, who presented with chest pain, cough and left pleural effusion, initially attributed to a pulmonary process. However, these were in fact the result of a left ventricular pseudoaneurysm following silent acute myocardial infarction. The diagnosis was suspected on echocardiography and confirmed by cardiac magnetic resonance imaging, and the patient underwent successful surgical pseudoaneurysm repair. This case illustrates an atypical presentation of a left ventricular pseudoaneurysm, in which the manifestations resulted from pericardial and pleural extension of the inflammatory process associated with contained myocardial rupture. The case demonstrates the need for a high index of suspicion, and the value of imaging techniques to confirm it, in order to proceed with appropriate surgical treatment, and thus modify the course of the disease.

Objective The aim of the study was to analyze respiratory system function after minimally invasive aortic valve replacement through right anterior minithoracotomy (RAT-AVR). Methods An observational study of 187 patients electively scheduled for RAT-AVR between January 2010 and December 2013. Pulmonary complications were analyzed and spirometry examinations were performed preoperatively, 1 week, 1 month, and 3 months after surgery. Results Hospital mortality was 1.1%. A double-lumen intratracheal tube was used in 88.2% and single-lumen intratracheal tube was used in 11.8% of patients. Pulmonary complications occurred in 10.8% of the patients. Prolonged (>24 hours) mechanical ventilation time was present in five patients (2.7%). The reasons were stroke (n = 1), perioperative myocardial infarction (n = 2), and pneumothorax (n = 2). Right pleural effusion, which occurred in 7.7% (n = 14) of patients, was the most frequent respiratory system complication. One week after surgery, the spirometry parameters decreased in comparison to the preoperative period, then after 3 months statistically significant improvement occurred; however, the spirometry parameters still had not returned to preoperative values. Multivariable median regression analysis shows that the presence of chronic obstructive pulmonary disease and pulmonary complications were associated with lower values of forced expiratory volume in 1 second after surgery. There was no statistically significant difference regarding spirometry values or incidence of pulmonary complications after surgery between patients in whom single-lung or double-lung ventilation was applied. Conclusion Pulmonary functional status measured with spirometry parameters was diminished after RAT-AVR surgery. Single-lung ventilation did not result in a higher rate of respiratory complications after RAT-AVR surgery.

Crimean-Congo Hemorrhagic Fever (CCHF) is a disease transmitted by the Crimean-Congo hemorrhagic fever virus (CCHFV), characterized by severe fever and hemorrhage and with a reported fatality level of 3-30%. Cerebral hemorrhage, gastrointestinal hemorrhage, severe anemia, shock, myocardial infarction, pulmonary edema, and pleural effusion may be seen as causes of death. Cardiac troponin T (cTn-T) is a biochemical marker with high sensitivity and specificity in myocardial injury. The purpose of this study was to determine the prognostic significance of serum troponin T levels in CCHF patients. Patients hospitalized with a diagnosis of CCHF and whose serum cTn-T was investigated were examined retrospectively. Patients were divided into two groups on the basis of presence or absence of hemorrhage. Data were subjected to statistical analysis. One hundred thirty-five CCHF patients and 72 control subjects were included. Hemorrhage was present in 48 (35.6%) patients. Mean serum cTn-T level was 17.3 ± 28.0 ng/L in the patients with hemorrhage, 9.98 ± 5.97 ng/L in the non-hemorrhage patients (P = 0.001) and 6.6P = 2.6 ng/L in the control samples (P < 0.001). At a cTn-T level cut-off point of 9 ng/L, area under the ROC curve was 0.797 (95%CI: 0.730-0.854), sensitivity 83.0%, specificity 87.5%, PPD 95.7%, and NPV 60.3%. At logistic regression analysis, a rise in cTn-T level above 14 ng/L increased the probability of hemorrhage in CCHF patients approximately threefold. An increased troponin T level may be a prognostic risk factor for hemorrhage in CCHF patients. This marker should therefore be borne in mind in determining treatment strategy in these patients. J.

We describe the case of a 23-year-old man presenting with recurrent pleuritic chest pain and prolonged fever after electrophysiology testing and placement of an implantable cardioverter-defibrillator because of a suspected arrhythmogenic right ventricular dysplasia. The clinical suspicion was initially directed toward pneumonia with pleural effusion and later toward an infection of the cardiac device complicated by septic pulmonary embolism. The definitive diagnosis of pulmonary embolism and infarction was suggested by a point-of-care thoracic sonography, performed at the bedside by a clinician caring for the patient, and then confirmed by contrast enhanced computed tomography, which also showed thrombosis of the left iliofemoral vein, site of percutaneous puncture for cardiac catheterization. Prolonged fever was attributable to a concomitant Epstein-Barr virus primary infection that acted as confounding factor. The present report confirms the value of bedside thoracic sonography in the diagnostic evaluation of patients with nonspecific respiratory symptoms.
