Insights

Elevated D-dimers and prolonged PT-INR indicate higher in-hospital mortality in infective endocarditis (IE). Shorter activated partial thromboplastin time (aPTT) predicts embolic events, while longer aPTT is linked to increased 1-year mortality in IE patients.

Area of Science:

  • Cardiology
  • Hematology
  • Infectious Diseases

Background:

  • Infective endocarditis (IE) is a serious infection affecting heart valves.
  • Hemostasis parameters play a crucial role in IE pathogenesis and outcomes.
  • Assessing prognostic markers in IE is vital for patient management.

Purpose of the Study:

  • To evaluate the clinical significance of key hemostasis markers in IE.
  • To determine the prognostic role of PT-INR, aPTT, fibrinogen, D-dimers, platelet count, and homocysteine in IE.
  • To identify predictors of mortality and embolic complications in IE patients.

Main Methods:

  • A cohort of 337 patients diagnosed with IE was analyzed.
  • Clinical, hemato-chemical, and echocardiography data were collected.
  • Coagulation parameters, including D-dimers and aPTT, were measured upon admission.

Main Results:

  • Elevated D-dimers and prolonged PT-INR were associated with increased in-hospital mortality (p=0.012, p=0.013).
  • Prolonged aPTT correlated with higher 1-year mortality (p=0.021).
  • Higher D-dimer levels and shorter aPTT were linked to embolic complications (p<0.001).

Conclusions:

  • Elevated D-dimers are a significant predictor of in-hospital mortality in IE.
  • Both high D-dimers and short aPTT are associated with a greater risk of embolic events in IE.
  • aPTT duration serves as a prognostic indicator for both short-term and long-term outcomes in IE.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
