Heart disease is the leading cause of death for men and women in the United States. Early heart disease often does not have symptoms, or the symptoms may be barely noticeable. This is especially true in older adults. That is why regular checkups with your doctor are important. Many forms of heart disease can be prevented or treated when people make healthy lifestyle choices and manage their health conditions.
