[ANTIHYPERTENSIVE THERAPY IN PATIENTS WITH COPD - THE SIGNIFICANCE OF NEBIVOLOL]

FARSANG Csaba

[The occurrence of hypertension associated with chronic obstructive pulmonary disease (COPD) is increasing. Recognising COPD is important in order to choose the appropriate antihypertensive drugs. Antihypertensive drugs that can be used to treat patients with hypertension and COPD include diuretics, ACE-inhibitors, angiotensine receptor blockers (AT1 receptor antagonists) and calcium antagonists, as well as cardioselective beta blockers, as these drugs decrease total and cardiovascular mortality. Of these agents, the importance of the most cardioselective one, nebivolol should be stressed, as this drug has no clinically significant effect on parameters of respiratory function, and, through its additional effects (namely by increasing the synthesis of NO), it has a beneficial effect on COPD-related deterioration of respiratory functions, haemodynamic alterations (cor pulmonale) and local factors that participate in the respiratory inflammation and endothelial dysfunction.]

[ENDOTHELIUM PROTECTION IN HYPERTENSIVE PATIENTS]

KÉKES Ede

[The author presents a review about the fundamental principles of normal endothelial function and the main causes for the development of endothelial dysfunction. First of all, endothelial dysfunction results in structural alterations in the wall of the vessel - the „vascular remodelling” in hypertension - and that is the base of hypertensive microangiopathy and target organ damage. In patients with high blood pressure the reactivity of vessels is impaired by the endothelial dysfunction. The members of the main drug groups can influence the vasoactive factors produced in endothelium differently. This different effects of drugs create different clinical benefits. Especially, the ACE inhibitors, the calcium antagonists (mostly the new generation of dihydropyridines) have endothelial protective effects, but some β-blockers, α-1 adrenergic blockers and - in a totally different way of action - the statins are capable of influencing the endothelial dysfunction.]
