Coretta Scott King's family is optimistic she will make a full recovery from a minor heart attack and a major stroke that impaired her ability to speak and affected her right side.

Says her daughter, Yolanda King, "We are completely assured she will come to a complete recovery."

Dr. Charles Wickliffe, a cardiologist at Piedmont Hospital, says King - the widow of slain civil rights leader Martin Luther King Jr. - had a blood clot that moved from her heart and lodged in an artery in the left side of her brain, The Associated Press

Dr. Wickliffe says, "This same clot caused a small heart attack and a big stroke."

King was hospitalized Tuesday and listed in fair condition early Friday. She is being treated with blood thinners to prevent more problems and prepare for the long days of rehabilitation.

The stroke caused weakness in King's right arm, right leg and right side of her face, and left her unable to speak. She will remain in the hospital for days, receiving intensive therapy.

Martin Luther King III says the family decided to disclose Coretta Scott King's condition after first withholding it because it was important "to bring some clarity."
