Many cardiovascular conditions can benefit from the prevention strategies described in this article. However, there are still other specific strategies that can be used to prevent deep vein thrombosis (DVT). DVT is a condition in which a blood clot (thrombus) has formed in one of the deep veins. If the clot breaks loose, it could cause a pulmonary embolism or other possibly fatal event. Regular exercise is an excellent strategy for preventing DVT because it promotes strong muscles and good circulation.

Because there is always a small risk of DVT associated with surgery, you should perform calf and leg exercises before surgery and resume activity as soon as possible after surgery. If you are confined to a bed or chair, regular stretching and leg movement are vital, especially if you sit at a desk all day or travel on long trips. You should avoid smoking, sitting with crossed legs and wearing tight garments below the waist such as garters or knee-high hosiery. Maintaining a healthy weight is equally important.

Preparing questions in advance can help patients have more meaningful conversations with their physicians about their conditions. Patients may wish to ask their doctors the following questions about ways to keep a healthy heart:

1. I do not know much about my family history. Can you determine my risk of heart disease without that information?
   
   
2. Many of my relatives have coronary artery disease. Will I get it as well?
   
   
3. I quit smoking years ago. Can that still affect the condition of my heart?
   
   
4. I eat a healthy diet but my cholesterol level is still high. Is this a problem?
   
   
5. I am in general good health with few risk factors for heart disease. Is there anything else I should do to protect my heart?
   
   
6. If I am taking medications to lower cholesterol, do I still need to change my diet?
   
   
7. How much do I need to exercise to help my heart?
   
   
8. I have already had a heart attack. Will any changes prevent another one?
