[Effects of cold air activity on serum catecholamine level in patients with cardiovascular or cerebrovascular disease].

ABSTRACT

OBJECTIVE: To study the influence on serum catecholamine (CA) in process of cold air activities. METHODS: Residents of Zhangye City in Gansu Province were selected by means of random cluster sampling. Dopamine (DA), adrenaline (AD), norepinephrine (NE) were measured before, in the transit and after the cold air transit. RESULTS: The DA of cases and control group have notable changes before, in and after the cold air transit, statistics test have significant difference (P < 0.05), multiple comparison have significant difference (P < 0.05) in DA changed obviously (P < 0.05) of control group. Before and mid cold air activity, the DA and NE level have the differences of case group. CONCLUSION: The cold air activities have the influence on catecholamine level in health people and patients. DA and NE may play the critical role in disease happening.
