目的:相关性分析近两年上海的气象因素及心力衰竭发病患者之间的关系,探讨影响心力衰竭高发的天气气候条件,为开展疾病预防和干预提供了理论和实践依据。方法:前瞻性统计2011年1月-2012年12月上海市胸科医院急诊的心力衰竭人数,并与同期气温,气压,湿度等气象资料进行相关性分析。结果:温度、气压、湿度对心衰的发生具有显著的影响。心力衰竭数与平均气温、最高气温、最低气温呈显著负相关,而与日平均气压呈显著正相关。前期相对湿度变化与心衰数显著相关。温度对心力衰竭数的影响具有滞后效应。结论:气温、气压及湿度与心力衰竭发病有明显相关,揭示了急性呼吸系统感染高发的天气气候条件,为开展疾病预防和干预提供了理论和实践依据。
OBJECTIVE: To analyze the relationship between the meteorological factors in Shanghai and the incidence of heart failure in the past two years, and to explore the weather and climatic conditions that affect the high incidence of heart failure, providing theoretical and practical basis for disease prevention and intervention. Methods: We prospectively collected the number of heart failure patients in Shanghai Chest Hospital from January 2011 to December 2012, and analyzed the correlation with the meteorological data of temperature, air pressure and humidity in the same period. Results: Temperature, pressure and humidity had a significant effect on the occurrence of heart failure. There was a significant negative correlation between the number of heart failure and the average temperature, the highest temperature and the lowest temperature, but positively correlated with the mean daily pressure. Pre-relative changes in relative humidity and heart failure were significantly correlated. The effect of temperature on the number of heart failure has a hysteresis effect. Conclusion: The temperature, pressure and humidity are significantly correlated with the incidence of heart failure, revealing the weather and climatic conditions of high incidence of acute respiratory infection, and provide theoretical and practical basis for disease prevention and intervention.
