Kraftigare sammandragning av den glatta luftrörsmuskulaturen vid en given retning än vad som är normalt. Detta tillstånd ses hos praktiskt taget alla symtomatiska astmapatienter. Den påtagligaste mani festationen av muskelsammandragningen är minskade luftvägsdimensioner, vilka enkelt kan mätas i samband med lungfunktionstester.
Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory.
