[Troponins and chronic kidney disease]
Summary
High-sensitivity cardiac troponin (hs-cTn) assays present challenges in diagnosing acute myocardial infarction (AMI) in chronic kidney disease (CKD) patients due to elevated baseline levels. This review examines hs-cTn utility for AMI diagnosis and prognosis in CKD.
Area of Science:
- Cardiology
- Nephrology
- Biomarker Research
Background:
- Coronary thrombosis has a long history, with acute myocardial infarction (AMI) distinguished from angina pectoris in 1912.
- Diagnostic tools evolved from ECG and basic labs to cardiac enzymes and finally troponins, with high-sensitivity assays emerging in 2010.
- Chronic kidney disease (CKD) patients face increased cardiovascular risk, complicating the interpretation of cardiac troponin levels.
Purpose of the Study:
- To review the diagnostic role of high-sensitivity cardiac troponin (hs-cTn) in patients with CKD for acute myocardial infarction (AMI).
- To evaluate the prognostic significance of elevated hs-cTn levels in CKD patients without AMI.
Main Methods:
- Literature review focusing on hs-cTn assays in CKD populations.
- Analysis of studies investigating hs-cTn for AMI diagnosis in CKD.
- Examination of research on hs-cTn as a prognostic marker in CKD patients without AMI.
Main Results:
- Elevated baseline hs-cTn levels are common in CKD patients, posing interpretation challenges for AMI diagnosis.
- hs-cTn assays require careful consideration in CKD for accurate AMI detection.
- Elevated hs-cTn levels in CKD patients without AMI may hold prognostic value for cardiovascular events.
Conclusions:
- The interpretation of hs-cTn in CKD requires specific strategies to differentiate AMI from other causes of troponin elevation.
- hs-cTn assays are valuable tools, but their application in CKD necessitates a nuanced approach for both diagnosis and prognosis.

627
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

1.2K
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
