Treatment of pulmonary hypertension in chronic bronchitis and emphysema.
SIR,-We read with interest the leading article by Dr John Rees on the treatment of pulmonary hypertension in patients with chronic bronchitis and emphysema (24 November, p 1398). An appreciable, but unknown, number of patients with hypoxia also develop polycythaemia, and in these cases reducing packed cell volume may help to ameliorate pulmonary hypertension. Blood viscosity rises -exponentiall...

متن کاملDeep vein thrombosis: diagnosis and treatment.
This article aims to give nurses an insight into proximal deep vein thrombosis (DVT). DVT is relatively common and is associated with significant morbidity and mortality. Complications such as post-thrombotic syndrome, venous leg ulcers, recurrent venous thromboembolism (VTE) - pulmonary embolism (PE) or DVT - and pulmonary hypertension can develop following DVT diagnosis. There is also a risk ...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
