Rule Out

Presentation of a 62-year-old man with baseline chronic obstructive pulmonary disease admitted to the hospital with dyspnea and newly diagnosed COVID-19 infection. CT scan of the chest was obtained to rule out pulmonary embolism. This revealed a mural thrombus of the inner curvature of the aortic arch with a floating component. Therapeutic full dose anticoagulation was initiated in combination with close clinical observation and treatment for modest hypoxia. He did well for 1 month and then returned with ischemic rest pain of the right foot. Angiography revealed thrombosis of all 3 tibial arteries in the right leg. Percutaneous mechanical thrombectomy with tissue plasminogen activator injection and angioplasty was performed with success in 1 tibial artery to achieve in line flow to the foot. After continued anticoagulation, the remainder of the tibial arteries autolysed and the aortic thrombus was noted to be resolved 4 months later. A brief pathophysiology discussion is included.

Introduction: In recent years, COPD is observed as not an isolated, but an associated pathology, in particular, concurrent with metabolic syndrome. The aim of the research is to identify the differences in changes of the rheopulmonography parameters (RPG) depending on the presence of hypertrophy or atrophy of the right ventricular myocardium in patients with COPD concurrent with metabolic syndrome.. Materials and methods: We studied changes in rheopulmonography (RPG) in 145 patients with chronic obstructive pulmonary disease (COPD) concurrent with metabolic syndrome. Results: We detected precapillary hypertension of the pulmonary circulation in patients with right ventricular myocardial hypertrophy: anacrotism serration; flattened peak of the systolic wave; decreased Vcp; high placement of incisura; horizontal course of catacrotism; decreased amplitude of the systolic wave (in this case, due to a greater increase in the resistance of the blood flow in the pulmonary vessels than the decreased impact volume of the right ventricle); prolonged Q-a (in this group of patients, it depends more on hypertension of the pulmonary circulation than on the reduction of contractile function of the myocardium). In atrophy of the right ventricular myocardium, the following changes in the RPG were revealed: decreased systolic wave at its dramatic rise; prolonged Q-a (in this case, due to the weakened heart contraction); Vmax reduction (it reflects the reduction of myocardial contractility); in hypertrophy of the myocardium, Vcp., unlike RPG, does not decrease, which is explained by the decrease in the pressure of the pulmonary circulation. Conclusions: We believe that these changes in RPG allow differentiating hypertrophy and right ventricular myocardial atrophy along with established diagnostic criteria, and can be used as markers for the diagnosis and treatment of COPD concurrent with metabolic syndrome.

Aortic Thrombus

Thrombus formation in a morphologically normal a aorta is a very rare event. A 50-year-old man with a his- s tory of chronic obstructive pulmonary disease, pre- e sented to the emergency department with pulmonary C edema. Transthoracic and transesophageal echocardio- t graphy revealed a highly mobile, pedunculated floating c thrombus in the descending thoracic aorta 3-4 cm dis- t tal to the origin of the left subclavian artery. The orig- t inal lumen of the aorta was almost obliterated by the thrombus. The aortic wall was free of any atheroma. Thrombolytic treatment was administered, but 3 hours d after starting streptokinase, he developed sudden and severe low-back pain accompanied by loss of lower-extremity pulses which were patent on admission. Cardiopulmonary arrest developed within an hour and the patient died despite resuscitation. The potential causes of aortic thrombus, the clinical spectrum that the patients may present, diagnostic methods, and therapeutic options are discussed.

The Impact

The formation and progression of chronic dust bronchitis and chronic bronchitis of toxic-chemical etiology, chronic obstructive pulmonary disease is accompanied by an increase in the degree of ventilation disorders, echocardiographic signs of hypertrophy and dilatation of the right ventricle are formed, typical for chronic pulmonary heart disease. The progression of disturbances in the function of external respiration in dusty lung diseases leads to a decrease in myocardial contractility. The detection of hemodynamic disturbances at the early stages of the development of occupational lung diseases indicates the need for individual monitoring of the functional state of the cardiovascular system in the process of contact with industrial aerosols, especially in groups of workers with long-term exposure.

The benefit of non-invasive ventilation (NIV) in stable chronic obstructive pulmonary disease (COPD) remains controversial. However, there is increasingly more evidence of NIV efficiency, especially high-flow NIV. This review presents the old and the new evidence of NIV effectiveness in stable COPD, considering pathophysiological arguments for NIV in COPD. Guidelines, randomized controlled trials (RCTs) and crossover studies included in review and metaanalysis based on patient-reported outcomes (PROs) have been analyzed. The role of NIV in rehabilitation and in palliative care and the role of telemedicine in relation with NIV are still up for debate. Challenges in choosing the right device and the optimal mode of ventilation still exist. There are also discussions on the criteria for patient inclusion and on how to meet them. More studies are needed to determine the ideal candidate for chronic NIV and to explain all the benefits of using NIV.

AIM: To assess the interference of nail polish on the reading of peripheral oxygen saturation in patients with chronic obstructive pulmonary disease on the step exercise. METHODS: In this study, there was the inclusion of patients with chronic obstructive pulmonary disease, current non-smokers, of both sexes. Four different colours of nail polish were used in the present study (base, light pink, red and brown), randomly distributed among the fingers of the right hand, with the corresponding fingers on the opposite hand being controls. Saturation was measured at rest, with and without the polish, and also during the 4th, 5th and 6th minutes of the exercise programme. RESULTS: The experimental universe included 42 patients with ages of 62.9±8.7 years. In the exercise considered, the red colour reduced it in the fourth minute of the exercise (p=0.047). In contrast, the brown colour reduced saturation at rest and also during the course of exercise (p=0.01). CONCLUSION: In patients with chronic obstructive pulmonary disease, the red and brown colours interfered with the reading of the peripheral oxygen saturation during exercise. This study is registered at the Brazilian Register of Clinical Trials (Registro Brasileiro de Ensaios Clínicos) under No. RBR-9vc722.

Background and Aims: Chronic obstructive pulmonary disease (COPD) is highly prevalent in the Nepalese population. It is associated with significant extrapulmonary effects among which cardiovascular complications are most common. Echocardiography evaluation mainly focused on effects on the right heart function is a salient tool to evaluate the presence of degree of pulmonary hypertension and also identify those group of patients who need more early aggressive therapy for the underling lung disease . We aimed to prospectively study the patients with diagnosed COPD with echocardiogram for evaluating the right heart.Methods: An observational, cross sectional study was done on 50 patients with COPD who were admitted at Bir Hospital and underwent echocardiographic evaluation from Dec 2015 –Dec 2016. All echocardiogaphic parameters focused on right heart and its function were assessed .Results: Out of total 50 COPD patients studied, majority of them were female (32 patients. 64%). The mean age group of the studied patients was 60.9 ±11.4 years. Pulmonary hypertension defined as sPAP>30 mmHg was evident in all of the patients ; with 30 patients (60% ), 14 (28 %) and 6(12 %) patients having severe, moderate and mild pulmonary hypertension respectively. RV dysfunction was evident with reduced average TAPSE values (1.59± 0.38 cm) and elevated RIMP values (0.58±0.16).Conclusion: Majority of COPD patients had evidence of pulmonary hypertension. Echocardiogram can be a helpful tool to assess early changes on the right heart size and function in patients with COPD and also monitor these patients for rapid progression of the illness.Nepalese Heart Journal 2017; Vol 14(2), 9-12

Objective: To report an apparent pharmacokinetic interaction between clinafloxacin and theophylline in a patient with chronic obstructive pulmonary disease (COPD). Case Summary: A patient with a history of COPD was admitted for a fracture of the right femoral neck. Admission medications included extended-release theophylline 400 mg bid. The initial serum theophylline concentration was 81.03 µmol/L (normal 55—110). A subsequent concentration was subtherapeutic (46.62 µmol/L) and the theophylline dosage was increased to 300 mg tid. Therapeutic steady-state concentrations were achieved. The patient later developed pneumonia and was enrolled in a study of nosocomial acquired pneumonia involving clinafloxacin versus ceftazidime. He was randomized to receive clinafloxacin 200 mg iv ql2h. After clinafloxacin therapy was initiated, the serum theophylline concentration increased into the toxic range (155.96 µmol/L). Theophylline administration was held for 2 doses and the dosage then reduced to 200 mg tid. Serum concentrations decreased to within the therapeutic range. Discussion: The fluoroquinolones have been shown to interact with the hepatic metabolism of theophylline and increase serum theophylline concentrations. The quinolone metabolite, 4-oxo-quinolone, inhibits the N-demethylation of theophylline, leading to a decrease in the clearance of theophylline. The resultant rise in theophylline concentrations corresponds with the decrease in clearance and possible toxicity. In our patient, careful monitoring of theophylline concentrations and dosage adjustments resulted in the restoration of therapeutic serum concentrations. Conclusions: The observation of this drug interaction between clinafloxacin and theophylline suggests a need for prudent monitoring of theophylline concentrations. Dosage adjustments may be warranted when this combination of medications is used. Such action may prevent significant toxicities and prolonged hospitalization. Further controlled clinical trials in healthy volunteers are needed to substantiate the interaction between clinafloxacin and theophylline.
