Abstract PDF: BACKGROUND
The incidence of acute heart failure (AHF) increases in cold weather. Whether or not AHF has seasonal variation in Korea is unclear, and the influence of humidity on AHF incidence is also unclear. The aim of this study was to examine the correlation between the number of daily emergency department (ED) visits for AHF and the temperature and humidity in Korea.
METHODS
On a retrospective basis, we investigated the medical records of patients who visited the ED with dyspnea from Jan. 1, 2008 to Dec. 31, 2010. Inclusion criteria comprised both evidence of clinical symptoms and the presence of signs of pulmonary congestion on chest X-rays. Exclusion criteria included a medical history showing end-stage renal disease with dialysis or showing an acute ST elevation myocardial infarction. The number of daily ED visits for AHF was compared with meteorological data after stratifying temperature or humidity into 3 parts.
RESULTS
After stratification by humidity, the results revealed that the number of daily ED visits was significantly associated with minimum temperatures occurring one to 2 days prior to ED admission, although only in the lowest tertile of humidity (p = 0.012, p = 0.021, respectively). The relationship between humidity and daily ED visits for AHF was the same as that mentioned above (p = 0.016, p = 0.039, respectively).
CONCLUSIONS
The number of patients with AHF in Korea increases in cold weather, as is the case in other countries. Specifically, AHF incidence was related to temperature minimums occurring one to 2 days prior to ED admission, as well as with humidity.

Acute heart failure (AHF) has emerged as a major public health problem over the past 2 decades and AHF represents a period of high risk for patients, during which time the patients are more susceptible to have fatal outcomes or be re-hospitalized, compared to periods of chronic stable heart failure. The goals of AHF treatment are symptomatic relief and hemodynamic stabilization, which need accurate assessment of volume status and cardiac function of patients. Until now, there is a paucity of controlled clinical data to define optimal treatment for patients with AHF and most guidelines published by the American Heart Association or European Society of Cardiology have been generated by the consensus opinions of experts. In these guidelines, routine invasive hemodynamic monitoring of AHF patients is not recommended because there have not been any reports showing survival benefit in patients monitored with pulmonary artery catheters. At present, treatment strategies based on clinical characteristics such as pulmonary congestion and tissue hypoperfusion rather than invasive hemodynamic monitoring is widely accepted. In this article, we discuss an optimal management plan including appropriate assessment of the hemodynamic status of patients and treatment of AHF.
