Table Of Contents: Heart Health

1. Heart Disease
Heart disease is the number one cause of death in the U.S., most frequently due to coronary artery disease. This disease is the result of an accumulation of thick deposits of fat and calcium on the arterial walls. These deposits block blood flow, cutting off the supply of oxygen to the heart.
2. Hypertension – High Blood Pressure
Hypertension is blood pressure that exceeds the normal value of 120/80 mm/Hg and can come about as a result of a variety of factors. In many cases, the underlying cause is not clear. However, poor choices in diet and lifestyle can play major roles in promoting high blood pressure. Obesity, high fat and salt diets, stress, alcohol consumption and smoking are just some of the factors that contribute to hypertension. High blood pressure puts a great strain on the heart because it must pump more forcefully to keep blood moving in the right direction.
3. Keeping the Heart Healthy
Regular exercise, proper nutrition, weight control and stress management are just some of the more common ways to help promote a healthy heart. People who exercise regularly have much more efficient hearts and a corresponding blood pressure that reduces stress on heart function.
