The heat has claimed two more people in Maryland, bringing the total to 12, according to state officials. One was a senior from Harford County who was found inside a building with the temperature exceeding 100 degrees. The second was an adult from Baltimore City, found in a residence where the temperature exceeded 95 degrees. Like most of the others who have succumbed to the heat, they both had heart disease or high blood pressure. Authorities are warning people with heart problems to consult their doctors on potentially altering their medications, particularly diuretics, and stay hydrated.
