Endocarditis Guide: Causes, Symptoms and Treatment Options

The increase in infective endocarditis has taken place amid a broader debate about the impact of “harm-reduction” strategies — services including syringe exchange, which data shows as highly effective at preventing infectious disease transmission. Many of those patients soon wind up readmitted to the hospital for repeat infections. In recent years, such cases have engendered frustration from hospitals and additional stigma among health providers — even leading to public debates about whether patients with multiple endocarditis cases are worthy of additional care.

Papers of particular interest, published recently, have been highlighted as: •• Of major importance

Cardiac computed tomography (cardiac CT) scan further elucidated the PA that measured 6.9 x 8.4 x 7.2 cm as shown in Figures ​Figures33-​-44. The 2015 American Heart Association (AHA) guidelines on managing IE (published in Circulation) suggest avoiding surgery in people who inject drugs because of the risk of prosthetic infection. The 2020 joint guidelines of the American College of Cardiology (ACC) and AHA on valvular heart disease (published in JACC) provide only limited guidance. They do say valve repair is preferable to valve replacement when feasible (as is usually the case in younger patients). The infection can be caused by bacteria introduced into the blood stream.

Risk factors of infective endocarditis in persons who inject drugs

In the 10% to 20% of endocarditis patients who have artificial heart valves, infections that follow within 60 days of valve surgery often are caused by a staphylococcus, while endocarditis that occurs later most frequently is caused by a streptococcus. Surgical intervention is indicated if the patient has refractory heart failure, persistent or recurrent infections including bacteria and fungi, prosthetic valves, development of a ring abscess, fistulae or worsening conduction abnormalities. However, special considerations are involved in the surgical treatment of IE in the population of IDU.

Infective Endocarditis and Intravenous Drug Users: Never Was and Never Will Be Taken Lightly

  • Check with your local chapter or print the card from the association’s website.
  • Fluid resuscitation, antibiotics, and vasopressors were appropriately utilized.
  • When comparing primary and redo valve operations in the DU-IE cohort, the same risk model was used except that redo was defined as previous valve operation.
  • In the 10% to 20% of endocarditis patients who have artificial heart valves, infections that follow within 60 days of valve surgery often are caused by a staphylococcus, while endocarditis that occurs later most frequently is caused by a streptococcus.
  • Confocal laser scanning microscopic analysis of infected valve tissue demonstrates bacterial biofilms embedded with platelet collections.

Repeat imaging revealed that the PA had significantly increased in size. Despite optimal medical management, the patient’s condition deteriorated, and she, unfortunately, succumbed to her illness. Antibiotic treatment should start immediately after blood cultures are obtained.

International Patients

In general, antibiotics are given one to two hours before a high-risk procedure, and up to eight hours afterward. Before a dental procedure, an antiseptic mouth rinse also can be used, especially one containing chlorhexidine or povidone-iodine. DeSimone, the infectious disease specialist who was the lead author for the AHA’s new recommendations, acknowledged those doctors may be uncomfortable providing addiction medications, like writing a prescription for buprenorphine or connecting their patients with a methadone clinic. The resulting void forces other doctors — in this case, cardiologists or infectious disease specialists — to treat their patients’ addiction, which they’re sometimes ill-equipped to do. The Department of Justice has weighed in as well, issuing guidance and announcing a number of settlements and new lawsuits aimed at forcing health care facilities to admit patients who’ve been prescribed addiction medications like methadone or buprenorphine.

Using 3D-Printed Anatomical Models for Surgical Planning

Early infection, which occurs within two months of valve placement, is generally the result of intraoperative contamination of the prosthesis or of postoperative infection. The tricuspid valve may be more susceptible to heroin use, as heroin can cause an increase in pulmonary arterial pressure, creating more turbulence at the tricuspid valve. Substances such as cocaine and metamphetamines, on the other hand, increase systemic afterload, causing increased turbulence at the sites of the aortic and mitral valves.

  • A paper in the Journal of Cardiac Surgery presents the STOP score, a tool for predicting operative morbidity and mortality in individual patients with DUA-IE.
  • It depends on the type of germs causing the infection and whether there are other heart problems.
  • Another barrier to dalbavancin use is the lack of a defined optimal dosing and monitoring schedules.
  • Physical examination on presentation was significant for temperature of 39.3°C, controlled blood pressure, sinus tachycardia at a rate of 105 beats/min, and a respiratory rate of 28/min.

Community and healthcare related MRSA infections are increasing in prevalence, and are becoming more common in IE (6, 10, 11, 23). Infective endocarditis (IE), also called bacterial endocarditis, is an infection caused by bacteria that enter the bloodstream and settle in the heart lining, a heart valve or a blood vessel. IE is uncommon, but people with some heart conditions have a greater risk of developing it. Infective endocarditis, also called bacterial endocarditis, is an infection caused by bacteria that enter the bloodstream and settle in the heart lining, a heart valve or a blood vessel. A retrospective analysis was performed of all patients undergoing IV sotalol loading and oral sotalol initiation for ventricular arrhythmias, or IV sotalol loading for atrial arrhythmias between August 2021 and December 2023 at Northwestern University.

But for patients with addiction, each of those steps adds a new layer of complexity — in particular, lengthy hospital stays and ensuing withdrawal for patients accustomed to regular opioid use. Among people with opioid use disorder, the rate of endocarditis jumped from 4 per million per day to 30 per million per day. The sharpest increase occurred between 2021 and 2022 — a spike that the study’s authors attribute to the Covid-19 pandemic. Opioids such as morphine are sometimes used in the cardiovascular setting to reduce pain and anxiety. However, researchers are finding that there is also potential for prescribed opioids to adversely affect outcomes for patients with acute coronary syndrome. Recent data from American Heart Association researchers suggests that opioid use may interfere with medications used to manage and treat cardiovascular disease and stroke.
