My mom recently called with the news that she had gone to the hospital in the middle of the night. She had had chest pain and thought she was having a heart attack. By the next morning, she felt better and anticipated going home. At the end of my work day, she called and said they still hadn’t let her leave. It turns out they decided they should do an angiogram (cardiac catheterization) because my mom does have several risk factors for a heart problem, including age over 55yo, high blood pressure and diabetes.
