BACKGROUND: Echocardiographic myocardial dysfunction is reported commonly in sepsis and septic shock, but there are limited data on sepsis-related right ventricular dysfunction. This study sought to evaluate the association of right ventricular dysfunction with clinical outcomes in patients with severe sepsis and septic shock. METHODS: Historical cohort study of adult patients admitted to all intensive care units at the Mayo Clinic from January 1, 2007 through December 31, 2014 for severe sepsis and septic shock, who had an echocardiogram performed within 72 h of admission...

The subject was an 83-year-old female; she had a history of Propionibacterium acnes-related sarcoidosis at the age of 79 years. At diagnosis, she was treated with clarithromycin and achieved remission. Four years later, during a routine physical check-up, she presented with pulmonary opacities and swelling of multiple lymph nodes. A definitive diagnosis of lymphoma could not be made by inguinal lymph node biopsy. The patient's general condition was good, and we observed her clinical course. Oh the 56th day of her illness, she died suddenly...

BACKGROUND: Tumor embolisms (TE) are an underappreciated source of pulmonary embolisms in sarcoma. Most evidence in the literature is limited to case reports and none have described the presence of TE secondary to myxofibrosarcoma. We report the first case of myxofibrosarcoma TE and perform a review of the literature for TE secondary to bone and soft tissue sarcomas (STS). CASE PRESENTATION: A 36-year-old female presented with debilitating pain of the right upper extremity secondary to a recurrent soft tissue sarcoma...

Acute respiratory distress syndrome (ARDS) is burdened with significant mortality, mainly in connection with circulatory failure. The right ventricle (RV) is the weak link of hemodynamic stability among ARDS patients and its failure, also named "severe" acute cor pulmonale (ACP), is responsible for excess mortality. Driving pressure ≥18 cmH2O, PaCO2 ≥48 mmHg and PaO2/FiO2 <150 mmHg are three preventable factors recently identified as independently associated with ACP, on which ventilator strategy designed to protect the RV has to focus...

RATIONALE: The original in vivo study of ventilator-induced lung injury by Webb and Tierney (1974) reported that high VT with zero PEEP caused overwhelming lung injury, subsequently shown by others to be due to lung shear stress. OBJECTIVE: To reproduce the lung injury and edema in the 'Webb and Tierney' study and investigate the mechanism. METHODS: Sprague-Dawley rats (≈400 g) received mechanical ventilation for 60 min according to the protocol of Webb and Tierney (14/0, 30/0, 45/10, 45/0 cmH2O)...

Pulmonary embolism (PE) is an important cause of perioperative morbidity and mortality. In patients with suspected PE, electrocardiogram (ECG) alone is thought to have a limited utility due to its low sensitivity and specificity. This case report describes a patient with intraoperative PE presenting with hypotension and hypoxemia for whom the ECG finding of SIQIIITIII was key in identifying acute cor pulmonale. The ECG was paramount in our decision to acquire computed tomography angiography to confirm the diagnosis, reinforcing its invaluable role in early detection of intraoperative PE...

Hypoxic hepatitis (HH) is characterized by marked and transient elevations in liver enzyme levels in the absence of other potential causes of liver injury. Although rare, it can occur in the presence of hemodynamic instability and hypoxemia in patients with cor pulmonale. We report two cases of perioperative HH in patients with severe pulmonary disease and cor pulmonale. The first case is of a patient with cor pulmonale who underwent hemiarthroplasty for a femur fracture. Transient hypotension developed during spinal anesthesia and severe hypoxemia were observed in the postoperative period...

In 2005, the combined pulmonary fibrosis and emphysema (CPFE) was first defined as a distinct entity, which comprised centrilobular or paraseptal emphysema in the upper pulmonary lobes, and fibrosis in the lower lobes accompanied by reduced diffused capacity of the lungs for carbon monoxide (DLCO). Recently, the fibrosis associated with the connective tissue disease was also included in the diagnosis of CPFE, although the exposure to tobacco, coal, welding, agrochemical compounds, and tire manufacturing are the most frequent causative agents...

BACKGROUND AND PURPOSE: In cor pulmonale, the increased afterload imposed on the right ventricle (RV) generates a maladaptive response, impairing the contractile cardiac function. Oxidative mechanisms play an important role in the pathophysiology and progression of this disease. The administration of pterostilbene (PTS), a phytophenol with antioxidant potential, may represent a therapeutic option. In the present study, we evaluated the effect of PTS complexed with hydroxypropyl-β-cyclodextrin (HPβCD) on hypertrophy, contractile function and oxidative parameters in the RV of rats with pulmonary hypertension, induced by the administration of monocrotaline (MCT)...

We report the case of a previously healthy man who presented with subacute dyspnoea after a long drive. He developed hypoxic respiratory failure, thought secondary to a massive pulmonary embolism and was treated with tissue plasminogen activator but died in the hospital despite aggressive medical measures. Autopsy revealed pulmonary tumour thrombotic microangiopathy (PTTM) from papillary renal cell carcinoma. PTTM is a rare clinicopathological syndrome that clinically results in symptoms of dyspnoea and right heart failure...

Acute respiratory distress syndrome (ARDS) is a severe respiratory condition that is characterized by rapidly progressive hypoxemia with noncardiogenic pulmonary edema. Despite the improvement of therapeutic methods, the mortality of ARDS is in the range of 40%-50% all over the world. Some studies have shown that a significant number of patients with ARDS had acute cor pulmonale (ACP), and ACP is independently associated with the mortality of patients with ARDS, which has attracted wide attention in recent years...

Chronic cor pulmonale is defined as right ventricular failure secondary to pulmonary hypertension. Our study reviewed all cases of chronic cor pulmonale secondary to respiratory diseases in a ten-year period (2004-20014) in the Department of Child Health, Korle-Bu Teaching Hospital, Ghana. Nine cases of chronic cor pulmonale were recorded during the period. The age range was 1-9 years (average age = 3 years). Obstructive sleep apnoea secondary to adenoid hypertrophy was the commonest cause of pulmonary hypertension...

INTRODUCTION: Pulmonary hypertension (PH) is a disorder of the pulmonary vasculature with high mortality and bears a large economic burden on the healthcare system. We conducted a review of the largest inpatient database in the United States and analyzed the trends in hospitalizations due to PH from the turn of the century (2000) to 2013 to evaluate the rate of hospitalizations and determine the cost and mortality associated with PH. MATERIAL AND METHODS: We analyzed the National Inpatient Sample Database (NIS) for all patients in which PH (Primary or Secondary) or cor pulmonale was the primary discharge diagnosis (ICD-9: 416...

Atmospheric fine particulate matter 2.5 (PM 2.5) may carry many toxic substances on its surface and this may pose a public health threat. Epidemiological research indicates that cumulative ambient PM2.5 is correlated to morbidity and mortality due to pulmonary and cardiovascular diseases and cancer. Mitigating the toxic effects of PM2.5 is therefore highly desired. Bufei Huoxue (BFHX) capsules have been used in China to treat pulmonary heart disease (cor pulmonale). Thus, we assessed the effects of BFHX capsules on PM2...

Cystic fibrosis (CF), the most common autosomal recessive lethal disease in Caucasians, causes chronic pulmonary disease and can lead to cor pulmonale with right ventricular dysfunction. The presence of the cystic fibrosis transmembrane conductance regulator (CFTR) in cardiac myocardia has prompted debate regarding possible defective ion channel-induced cardiomyopathy. Clinical heart disease in CF is considered rare and is restricted to case reports. It has been unclear if this is due to the lack of physiological importance of CFTR in the heart, the relatively short lifespan of those with CF, or a technical inability to detect subclinical disease...

BACKGROUND: Levels of plasma brain natriuretic peptide (BNP) have been shown to be elevated in chronic obstructive pulmonary disease (COPD) especially in connection with cor pulmonale (CP) and the late stages of the disease. BNP is also raised in left sided heart failure which sometimes coincides with COPD. Whether BNP is elevated in subjects with mild-moderate stable COPD and normal left ventricular function is not clear. OBJECTIVE: To investigate BNP levels in subjects with mild-moderate COPD and normal left ventricular function...

The heart may be affected directly or indirectly by a variety of protozoa and helminths. This involvement may manifest in different ways, but the syndromes resulting from impairment of the myocardium and pericardium are the most frequent. The myocardium may be invaded by parasites that trigger local inflammatory response with subsequent myocarditis or cardiomyopathy, as occurs in Chagas disease, African trypanosomiasis, toxoplasmosis, trichinellosis and infection with free-living amoebae. In amoebiasis and echinococcosis, the pericardium is the structure most frequently involved with consequent pericardial effusion, acute pericarditis, cardiac tamponade or constrictive pericarditis...
