Enbrel is one of the brand names of the generic drug etanercept. According to the website NetDoctor UK, Enbrel works by decreasing the production of a tumor necrosis factor alpha, which is a protein in the body linked to inflammatory response and inflammatory activities. Drugs.com notes that it is used to treat plaque psoriasis, rheumatoid arthritis symptoms and juvenile arthritis. In addition to overall side effects, Enbrel carries risk of some specific side effects on the heart.
Changes in Blood Density
Enbrel can cause changes in blood density levels, which can affect regular heart operation. According to the Arthritis Research UK website, Enbrel has been linked to negative changes in blood cell counts. Unexplained bruising, bleeding or paleness are a cause for medical concern as a result, since NetDoctor UK reports that low red blood cell counts can cause problems with regular blood clotting.
Opportunistic Infections
One of the side effects that Enbrel has on heart health and function is opening up the heart to opportunistic infections. Drugs.com notes that lowering the blood cell count can weaken the body's immune system, and any sign of an infection while on Enbrel should be taken seriously. A fever, feeling of general poor health or other signs of infection specific to the patient's body should be reported to a doctor for the appropriate next steps.
Congestive Heart Failure
According to MedBroadcast.com, Enbrel has been linked to an increased risk of congestive heart failure. This is considered to be a rare but extremely serious side effect of Enbrel use, and patients with a history of heart problems should discuss it with their doctors. Warning signs of Enbrel-related congestive heart failure include shortness of breath and swelling of the feet and ankles. MedBroadcast.com states that if these warning signs are evident, immediate medical attention should be sought.
