BACKGROUND
47%
= 116 million people in the United States have hypertension
41%
Asthma patients have experienced Asthma attacks in the last 12 months
Data from CDC
How Might We design a medical device to solve these problems?
Research
The Impact of Feelings on Cardiac Attack
The effect of negative emotions on the
acute onset of asthma
Depression
is the biggest impact. It tends to lead to morbidity.
Angry and hostile
Short-Term and Long-Term stimulation of anger can increase the incidence.
