We studied one hundred consecutive patients with rheumatoid arthritis from the cardiological point of view through non invasive methods to detect the frequency of cardiovascular complications. Seventy three (73%) were females and twenty seven (27%) males. Mean age, 48.6 years. Mean age of presentation of the disease, 34.2 years. Mean age of duration of the illness, 21.8 years. Fifty seven per cent had some type of cardiopulmonary complication. Clinically 52 per cent referred some type of cardiopulmonary symptoms. The physical examination was abnormal in 27 per cent. Rheumatoid factor (Waaler-Rose) was positive in 82 per cent. The cardiac X ray series was abnormal in 33 per cent, the resting electrocardiogram in 48 per cent and the M mode echocardiogram in 52 per cent of the cases. The complications detected were: pericardial effusion (21%); pleural effusion (9%); pulmonary fibrosis (6%) which represents a higher incidence of previously reported in the literature; congestive heart failure (10%); valvular lesion (9%) among those are included six patients with valvular heart disease of non detectable etiology; ischemic heart disease (8%); myocarditis (6%); rythm disturbances (22%) and conduction defects (20%) including a 46 year old female patient who developed a complete AV block during an exacerbation of her illness, requiring the insertion of definitive pacemaker. Our results showed that some of the detected lesions are in part more frequent and severe than those reported in the literature, probably due to, that on one hand their search was intentional and on the other, our group was constituted by with severe and long standing rheumatoid arthritis.

We report a case of secondary antiphospholipid syndrome (APS) occurring in a progressive systemic sclerosis (PSS) patient who took herbal medication. Clinical findings compatible with APS included positive IgM anticardiolipin antibody (ACL), thrombocytopenia, and obstruction of the left radial artery on digital subtraction angiography (DSA). Clinical findings compatible with PSS included sclerodactyly and digital ulcers, Raynaud's phenomenon, pulmonary fibrosis and pulmonary hypertension, proteinuria and renal mesangial reaction, and myocarditis.

We describe a 40-year-old man with limited scleroderma who presented with acute heart failure following a flu-like illness. He was known to have incomplete left anterior bundle branch block, initial isolated pulmonary hypertension with enlarged right atrium, and no pulmonary fibrosis. He received therapy for acute heart failure and was transferred to a scleroderma centre for specific treatment of scleroderma cardiomyopathy. Investigations showed raised inflammatory markers and diffuse hyperechogenic thickening of the myocardium on echocardiography. Contrast-enhanced (Gd-DOTA) cardiovascular magnetic resonance imaging (CV-MRI) showed multiple areas of non-homogeneous delayed hyperenhancement in the left ventricle, suggestive of myocarditis. Antiadenovirus IgM antibodies were detected with a titer consistent with recent infection. Six weeks later a repeat Gd-DOTA CV-MRI showed an almost complete resolution of the areas of hyperenhancement and there was a significant reduction in the adenovirus antibody titer with serological conversion to IgG. To our knowledge this is the first report of viral myocarditis in scleroderma. Infections are important causes of morbidity and mortality in this disease and should always be included in the differential diagnosis of cardiac symptoms. We propose that contrast-enhanced CV-MRI is valuable in a non-invasive diagnosis of heart disease in patients with scleroderma.

Q fever is a bacterial infection affecting mainly the lungs, liver, and heart. It is found around the world and is caused by the bacteria Coxiella burnetii. The bacteria affects sheep, goats, cattle, dogs, cats, birds, rodents, and ticks. Infected animals shed this bacteria in birth products, feces, milk, and urine. Humans usually get Q fever by breathing in contaminated droplets released by infected animals and drinking raw milk. People at highest risk for this infection are farmers, laboratory workers, sheep and dairy workers, and veterinarians. Chronic Q fever develops in people who have been infected for more than 6 months. It usually takes about 20 days after exposure to the bacteria for symptoms to occur. Most cases are mild, yet some severe cases have been reported. Symptoms of acute Q fever may include: chest pain with breathing, cough, fever, headache, jaundice, muscle pains, and shortness of breath. Symptoms of chronic Q fever may include chills, fatigue, night sweats, prolonged fever, and shortness of breath. Q fever is diagnosed with a blood antibody test. The main treatment for the disease is with antibiotics. For acute Q fever, doxycycline is recommended. For chronic Q fever, a combination of doxycycline and hydroxychloroquine is often used long term. Complications are cirrhosis, hepatitis, encephalitis, endocarditis, pericarditis, myocarditis, interstitial pulmonary fibrosis, meningitis, and pneumonia. People at risk should always: carefully dispose of animal products that may be infected, disinfect any contaminated areas, and thoroughly wash their hands. Pasteurizing milk can also help prevent Q fever.

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis. Rare and severe cardiovascular manifestations include pericarditis, arrhythmias, myocarditis, and aortic valve disease. Our patient is a 43-year-old female with typical pulmonary and renal lesions from GPA and also acute myocarditis, multiple episodes of ventricular tachycardia, and a severe reactive thrombocytosis.

Immune checkpoint inhibitors (ICIs), including inhibitors of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) have demonstrated prominent clinical benefits in a variety of cancers and have been rapidly applied to treat a variety of carcinomas such as melanoma, non-small-cell lung cancer, and head and neck cancer. Meanwhile, the occurrence of immune-related adverse events (irAEs) has been increasing. In this case, we report a 45-year-old man with metastatic nasopharyngeal carcinoma suffering from pulmonary fibrosis and myocarditis on the 4th day after receiving pembrolizumab treatment which belongs to anti-PD-1 drugs. Although the endomyocardial biopsy (EMB) could not be performed, the strong temporal association with pembrolizumab treatment and the specific changes of electrocardiograph, echocardiography and cardiovascular magnetic resonance (CMR) suggest that the myocardial injury and edema were related to pembrolizumab-induced myocarditis. With glucocorticoid treatment, the symptoms and myocardium lesion were almost resolved and the patient agreed to tapered chemotherapy with steroid treatment.

Coronavirus disease (COVID-19) is a severe infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that binds to the cells; angiotensin converting enzyme 2 (ACE2) receptor. In the first severe case of COVID-19 in Shenzhen city, we found that in addition to the typical clinical manifestations, our patient presented hemoptysis, refractory hypoxemia and pulmonary fibrosis-like changes on computed tomography (CT) involving alveoli and pulmonary interstitium in the early stage and acute pulmonary hypertension and right heart failure in the later stage, which were not completely justified by myocarditis, acute respiratory distress syndrome (ARDS), pulmonary fibrosis and high PEEP level. The lung compliance deterioration of this patient was not as serious as we expected, indicating classic ARDS was not existed. Simultaneously, the first autopsy report of COVID-19 in China showed normal-structured alveoli and massive thick excretion in the airway. Then, we speculated that the virus not only attacked alveolar epithelial cells, but also affected pulmonary vascular endothelial cells. Imbalance in the ACE2-RAAS- bradykinin axis and the cytokine storm could be an important mechanism leading to pathophysiological changes in pulmonary vascular and secondary refractory hypoxemia. Pulmonary vasculitis or capillaritis associated to immune damage and an inflammatory storm could exist in COVID-19 because of ground-glass opacities in the subpleural area, which are similar to connective tissue disease associated interstitial lung disease (CTD-ILD). Thus, this case elucidates new treatment measures for COVID-19.
