The point of increased pressure in relation to pulmonary capillary wedge pressure is divided into postcapillary (passive), capillary and precapillary (active) pulmonary hypertension (PH). We assume that reduction of alveolar oxygen partial pressure leads to a growth of mast cells not only peribronchially, but also especially perivascularly, causing pulmonary arteriolo-vasoconstriction during release of eicosanoids (mediators). The individual components (vasoconstrictive, obliterative, obstructive, reactive, nutritive, primary, porto-pulmonary) are discussed. Long-term elevated pulmonary artery pressure (increased arterial vasoconstriction) results in right heart hypertrophy, which begins particularly in the right heart ejection tract. Depending on the underlying parenchymal or vascular diseases, we must differentiate between chronic cor pulmonale parenchymal or vascular. Right ventricular catheterisation may be differentiated into compensated or decompensated situation. Timely normalisation of pulmonary artery pressure may even lead to regression of the right ventricular hypertrophy. Right ventricular contractility on hypoxia is basically different in adapted and non-adapted patients (important for therapy and prognosis). Progression of right ventricular muscle mass and constant myocardial vasculature will cause stenocardias; in that case, permanent oxygen insufflation is indicated.

The underlying severe and mostly progressive pulmonary vascular disease with unknown aetiology is defined as primary pulmonary hypertension (PPH) with three different pathomorphological subtypes, plexogenic pulmonary arteriopathy (PPA), thrombotic pulmonary arteriopathy (TPA) and pulmonary venoocclusive disease (PVOD). The endemic occurrence of PPH after the ingestion of anorexigenic drugs (aminorex fumarate) and toxic rapeseed oil lead to the hypothesis that PPH is a pulmonary vascular reaction to exogenous toxic agents on the base of a genetic disposition. The initial response could be an endothelial cell dysfunction leading to pathological proliferation of vascular smooth muscle cells, vasospasm and local disturbances of haemostasis. The derived therapeutic concepts with vasodilators (high dose calcium channel-blocking therapy, prostacyclin) and with anticoagulant drugs show some encouraging results.

Apart from a significantly higher number of inflammatory joint conditions in the MTX group there was no difference in the two patient groups at the beginning of the study. MTX treatment led clearly to a more conspicuous activity decrease of the illness (ESR, joint index) and a more favourable effect on the locomotor function. Furthermore, the sphygmomanometer readings (for grip strength determination), the dose reduction of the concomitant prednisolone medication as well as the doctor's opinion were in favour of MTX.
