Correlation Study Between Meteorological Factors and the Number of Daily Heart Failure Patients in Emergency Room at Fengxian District of Shanghai / 中国循环杂志

ABSTRACT

Objective: To analyze the relationship between meteorological factors and the number of daily heart failure (HF) patients for emergency room (ER) visit at Fengxian district of Shanghai in order to provide the experience for prevention and control of HF morbidity. Methods: Daily number of HF patients treated in ER of our hospital from 2012-01 to 2014-12 with corresponding meteorological, air pollution data at the same period were collected and analyzed by Spearman correlation study and multiple stepwise regression analysis. Results:①The differences of temperature, humidity, air pressure at 24-, 48-hour before and 48-hour after ER visit were positively related to the number of HF patients; the number of HF patients was signiifcantly related to the differences of temperature and air pressure at 48-hour before ER visit,P<0.001.②Multiple stepwise regression analysis showed that the most affecting meteorological factor for ER visit of HF patients was the daily lowest temperature,P<0.05, the second factor was the daily average relative humidity,P<0.05. Conclusion: Radical changes of temperature, relative humidity and air pressure elevated the number of HF patients for ER visit; daily lowest temperature and decreased relative humidity were the important factors for elevating the number of HF patients for ER visit.
