BACKGROUND: Dirofilaria immitis infection occurs in dogs and cats, both of which species are clinically affected by mature adult infections. Cats are uniquely affected by immature-adult infections with an inflammatory pulmonary disease called Heartworm-Associated Respiratory Disease (HARD). D. immitis infection causes pulmonary parenchymal and vascular pathology in the dog and cat. Dogs develop pulmonary hypertension and cor pulmonale, whereas the development of pulmonary hypertension is rare in the cat...

BACKGROUND: Emphysema is a progressive disease characterized by irreversible airspace enlargement followed by a decline in lung function. It also causes extrapulmonary effects, such as loss of body mass and cor pulmonale, which are associated with shorter survival and worse clinical outcomes. Ghrelin, a growth-hormone secretagogue, stimulates muscle anabolism, has anti-inflammatory effects, promotes vasodilation, and improves cardiac performance. Therefore, we hypothesized that ghrelin might reduce lung inflammation and remodelling as well as improve lung mechanics and cardiac function in experimental emphysema...

Children with biliary atresia (BA) following Kasai portoenterostomy have a high risk for portal hypertension, however, while variceal and hemorrhagic complications have been more commonly studied, less frequent but no less possibly devastating complications of hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPH) remain less well understood. HPS and PPH both occur in a setting of portal hypertension, however, paradoxically patients with HPS develop pulmonic vasculature dilation leading to shunting and hypoxia, while those with PPH develop an opposite progression of pulmonary vasoconstriction eventually leading to cor pulmonale and decompensation...

Cor pulmonale rat models were induced by a single intraperitoneal injection of monocrotaline(MCT), and the sham group received a single intraperitioneal injection of normal saline. After the model rats received intragastric administration of Qishen Yiqi droplet(QS) for 6 weeks, the contents of adenylate(ATP, ADP and AMP) in right myocardial tissues were measured by HPLC, and then the metabolism changes in myocardium of cor pulmonale rats with QS were investigated. The results showed that ATP, ADP, and AMP were well separated, with a good linearity within a certain range of concentration; and the recovery rates were within the range of 90%-108%...

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...
