Bacterial endocarditis is a serious heart infection that can be life-threatening if not treated properly. While it’s usually linked to certain heart conditions or intravenous drug use, cocaine use—especially when snorted or injected—can also increase the risk of developing this condition.

Bacterial endocarditis happens when bacteria enter the bloodstream and infect the inner lining of the heart. This can damage heart valves and lead to complications like heart failure or stroke. The infection is often caused by bacteria entering through broken skin or during procedures like surgery or dental work, but it can also happen from drug use, particularly with cocaine. If you or a loved one would like help to avoid cocaine use, then Contact us today and take the first step toward a healthier future.

Topic 01 · Mechanism

How cocaine use leads to bacterial endocarditis

Using cocaine can damage blood vessels and tissues, making it easier for bacteria to enter the bloodstream and travel to the heart. This is especially true for people who inject cocaine with non-sterile needles, which introduces bacteria directly into the bloodstream. Even snorting or smoking cocaine can damage the nasal passages or lungs, allowing bacteria to enter the body. Additionally, cocaine weakens the immune system, making it harder for the body to fight infections, creating the perfect storm for bacterial endocarditis.

Topic 02 · Symptoms

Symptoms to watch for

The symptoms of bacterial endocarditis can include:

  • Fever
  • Fatigue or weakness
  • Shortness of breath
  • Swelling in the legs, feet, or abdomen
  • Heart murmur (an abnormal heartbeat sound)
  • Aches and pains, including joint or chest pain

Topic 03 · Risk factors

How cocaine increases the risk

Cocaine has several harmful effects that increase the risk of bacterial endocarditis:

  • Damaging blood vessels.Cocaine restricts blood flow, making the heart more vulnerable to infection.
  • Weakening the immune system.Cocaine suppresses the body’s ability to fight off infections.
  • Dirty needles.Injecting cocaine with unclean needles can directly introduce bacteria into the bloodstream.
  • Damage to mucous membranes.Snorting cocaine can cause tears in the nasal passages, making it easier for bacteria to enter.

Topic 04 · Treatment
