Dyspnea on Exertion in Hemodialysis Patients

Cardiovascular Causes

The American Journal of Kidney Diseases recommends that left ventricular hypertrophy (LVH) be considered a significant contributor to dyspnea, affecting approximately 75% of patients by the start of hemodialysis therapy and impairing cardiac function 2
Congestive heart failure is a major cause of dyspnea in CKD patients, with cardiac structural changes beginning early in kidney disease progression, according to the American Journal of Kidney Diseases 3, 1
Dysrhythmias are common in dialysis patients, with ventricular dysrhythmias observed in up to 76% of maintenance dialysis patients, contributing to reduced cardiac output and dyspnea, as reported by the American Journal of Kidney Diseases 1, 4
Ischemic heart disease is prevalent even at dialysis initiation and increases the risk of cardiac dysfunction leading to dyspnea, according to the American Journal of Kidney Diseases 1

Anemia reduces oxygen-carrying capacity, leading to tissue hypoxia and dyspnea on exertion in CKD patients, with the National Kidney Foundation recommending hemoglobin targets generally in the range of 11.0-12.0 g/dL for CKD patients on dialysis receiving ESA therapy 6

Uremic lung disease can reduce lung compliance and gas exchange efficiency, as reported by the International Journal of Oral Science 7

Electrolyte fluctuations during dialysis, particularly potassium, calcium, and magnesium, can trigger dysrhythmias that worsen dyspnea, according to the American Journal of Kidney Diseases 1, 4

The American Journal of Kidney Diseases recommends that all dialysis patients undergo a routine 12-lead ECG at the initiation of dialysis to assess for cardiac abnormalities that may contribute to dyspnea 1
Echocardiography should be performed in all patients at the initiation of dialysis therapy to assess for cardiomyopathy, valvular disease, and pulmonary hypertension, as recommended by the American Journal of Kidney Diseases 1
Careful assessment of fluid status and achievement of dry weight is crucial for managing dyspnea related to fluid overload, according to the American Journal of Kidney Diseases 5
