Cardiac contraindications for smallpox vaccination
The Centers for Disease Control and Prevention (CDC) issued the following statement on cardiac risk factors and smallpox vaccination:
As a precautionary step, if you have been diagnosed by a doctor as having a heart condition with or without symptoms you should NOT get the smallpox vaccine at this time while experts continue their investigations. These include conditions such as:
- known coronary disease including:
- previous myocardial infarction (heart attack);
- angina (chest pain caused by lack of blood flow to the heart);
- congestive heart failure;
- cardiomyopathy (heart muscle becomes inflamed and doesn’t work as well as it should);
- stroke or transient ischemic attack (a "mini-stroke" that produces stroke-like symptoms but no lasting damage);
- chest pain or shortness of breath with activity (such as walking up stairs);
- other heart conditions under the care of a doctor.
In addition, you should NOT get the smallpox vaccine if you have 3 or more of the following risk factors:
- You have been told by a doctor that you have high blood pressure.
- You have been told by a doctor that you have high blood cholesterol.
- You have been told by a doctor that you have diabetes or high blood sugar.
- You have a first-degree relative (for example mother, father, brother, or sister) who had a heart condition before age 50.
- You smoke cigarettes now.
