Why Are African-Americans at Greater Risk for Heart Disease?

Heart disease has haunted generations of Robin Drummond's family. "I have a family history of heart disease on both sides," says the 55-year-old African-American and resident of Hammond, La. "I've had uncles, aunts, and grandparents who've died from heart attacks and heart disease, and two of my mother's brothers died four months apart.

  • Has your baby been urinating less often than usual?
  • Does your baby's color change when he or she is crying? If so, does the color quickly return to normal after crying stops?
  • What position does he or she seem most comfortable in when resting?
  • Has your baby ever passed out? If the child is older: Has your child ever complained of his or her heart beating in a strange way?
  • Did you have or were you exposed to rubella (German measles) or any other infections during your pregnancy?
  • Did you take any medicines, use illegal drugs, or drink alcohol during your pregnancy?
  • Do you have a family history of congenital heart defects?

Physical exam

The doctor will:

  • Check your child's weight and length.
  • Check your child's heart rate and blood pressure.
  • Listen to your child's heart and lungs with a stethoscope to detect whether a heart murmur is present. A heart murmur can be normal in children but should be checked by a doctor.
  • Check your child's heart rate (pulses) on the neck, wrist, legs, and feet.
  • Check your child's nail beds, lips, and skin for a bluish tint (cyanosis) and/or clubbing. Your doctor may also check the amount of oxygen in your child's blood with an oximeter.
  • Look at the skin over the blood vessels in the neck to see whether the vessels bulge. This may happen if the heart is weak (heart failure).
  • Look at and feel your child's belly to check for an enlarged liver. The liver may be enlarged in children who have heart failure.
