Recently, we’ve started to hear more about Lyme carditis as one potentially lethal manifestation of Lyme disease. What exactly is it, why does it happen, and how does it cause disease?
What is Lyme Carditis?
First of all, a little Latin. When you see the suffix “-itis”, it denotes inflammation – often caused by an infection. So, carditis literally means inflammation of the heart.
When a Borrelia infection enters the body, we know from animal studies that it disseminates quickly. It tries to find the tissues where it is most comfortable, and often that includes the heart. Borrelia can infect all parts of the heart – the myocardium, the pericardium, and the endocardium, the cardiac muscle, the valves, and even the aorta itself. The immune system senses the presence of the spirochete bacteria and induces inflammation, the first prong of the immune system’s response.

Lyme disease, if treated early, can usually be successfully eradicated with antibiotics. Unfortunately, as many patients know, if it is not diagnosed early, it can cause debilitating sickness and a myriad of symptoms that are much harder to treat. And not all treatments are covered by insurance, making the whole experience potentially very financially as well as physically draining.
