Introduction:
Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular risk in patients with chronic renal disease (CRD) on hemodialysis (HD).
Objective:
To show the usefulness of chest radiography in the diagnosis of LVH in CRD patients on HD.
Methods:
Cross-sectional study including 100 patients (58 men and 42 women), mean age 46.2 ± 14.0 years, with CRD of all causes, for at least six months on HD. Were obtained echocardiogram and chest x-rays of patients, always up to one hour after the end of HD sessions.
Results:
LVH was detected in 83 patients (83%), of whom 56 (67.4%) had the concentric pattern and 27 (32.6%) with eccentric pattern of LVH. Cardiomegaly - defined by cardiothoracic index (CTI) > 0.5 - was present in 61 patients (61%). The following were the sensitivity, specificity and accuracy, respectively, for the variable ICT: 66.2%, 70.5% and 68.0%. The Pearson correlation between ICT and index of left ventricular mass (LVMI) was 0.552 (p < 0.05) and positive likelihood ratio of 2.2.
Conclusion:
Chest radiography is a safe and useful as a diagnostic tool of LVH in CKD patients on HD.
