The American Heart Association will hold its annual Palmetto Heart Walk on Saturday, April 27th at Shelter Cove Community Park on Hilton Head Island. More than 700 supporters and survivors are expected to attend and raise funds to support cardiovascular research and education. The Heart Walk raises awareness that walking 30 minutes a day greatly reduces your risk of heart disease and stroke, which are America’s No. 1 and No. 5 killers.
