Assessment of The Clinical Course of Dyspnea and Its Association With Respiratory Rate in Patients With Acute Heart Failure Syndromes
Acute heart failure (AHF) is defined as a gradual or rapid change in heart failure (HF)
signs and symptoms, such as shortness of breath (also called dyspnea or breathlessness), leg
swelling, fatigue, breathlessness with exertion, trouble sleeping flat at night, and weight
gain resulting in a need for urgent therapy. AHF results in over 1 million hospitalizations
every year, resulting in an enormous public health burden. Approximately 1/3rd of patients
will either be re-hospitalized or die within three months, and the resultant financial costs
are large. As such, improving outcomes for AHF patients is critically important.
Shortness of breath is the most common reason why patients with AHF present to the ER. As
such, understanding how severe this symptom is, how much it improves with current treatments
is very important to both patients and physicians. The purpose of this study is to determine
the degree to which your shortness of breath improves during the first few days of
hospitalization and its association with how fast you are breathing.
