Lee Kun-Hee, the 72-year-old chairman of Samsung Electronics, is in a hospital in Seoul, South Korea after suffering a heart attack, reports The Wall Street Journal. He was sent to the emergency room after having trouble breathing late Saturday. Currently, he is in stable condition.

According to PC World, it is unclear how long Lee will have to be hospitalized. However, he is expected to make a full recovery. Lee has been in charge of the company since his father passed away in 1987. Set to take over after Kun-Hee is his son, Jay Y. Lee. Jay is currently the vice chairman and was previously the Chief Operating Officer.

Statistics from the U.S. Centers for Disease Control and Prevention (CDC), indicate that 715,000 Americans have a heart attack each year.  Of these, 525,000 are a first attack and 190,000 have already had a heart attack before.  The CDC also interviewed Americans to identify if there was a lack of education on heart attacks.  With 47 percent of sudden cardiac deaths occurring outside of a hospital, the CDC concluded that many Americans do not know when it is time to seek emergency medical care.

WebMD reports that commonly known symptoms of a heart attack are squeezing chest pain, shortness of breath, and a crushing chest pain that radiates down one arm.  However, these are more often seen in male victims.  Females experience subtler or less obviously related symptoms, such as pain in seemingly unrelated areas including the back, neck, jaw, and stomach.  Women also experience a fatigued feeling, primarily in the chest, which makes simple physical exertion difficult.
