Heart disease is under diagnosed especially in women. One simple indicator is a measure of blood pressure. The experts have now decided that pre-high blood pressure is 120-139 (systolic, the upper measure) and 80-89 (diastolic, the lower measure). Many people have no symptoms of high blood pressure. If there is heart disease in your family it may be a good idea to purchase an electric blood pressure monitor from a local pharmacy and monitor your blood pressure on a regular basis. Next time you go to the doctor, take your readings and have them reviewed. Taking care of your health with early preventative measures will help avoid more significant issues later.
