Why the study?
Do specific ECG criteria accurately diagnose echocardiographic LVH and LAE in middle-aged hypertensive patients without evident cardiovascular disease?
Do specific ECG criteria accurately diagnose echocardiographic LVH and LAE in middle-aged hypertensive patients without evident cardiovascular disease?
In middle-aged hypertensive patients, the SD+SV4 ECG criterion offers the highest sensitivity for diagnosing LVH, while PTFV1 is a valuable marker for detecting left atrial enlargement.
May improve ECG detection of LVH/LAE in middle-aged hypertensives; leaves open prospective validation before any practice change.
This article compared the performance of 18 electrocardiographic (ECG) left ventricular hypertrophic (LVH) criteria and four P‐wave indices for the diagnosis of echocardiographic (ECHO) LVH and left atrial enlargement (LAE), including the deepest S‐wave amplitude added to the S‐wave amplitude of lead V 4 (S D +SV 4 ) and P‐wave terminal force in lead V 1 (PTFV 1 ). A total of 152 middle‐aged hypertensive patients without evident cardiovascular diseases (CVDs) were enrolled. The gold standard for the diagnosis of LVH and LAE was ECHO left ventricular mass index (LVMI) and largest left atrial volume index (LAVI). For the detection of LVH, Sokolow‐Lyon voltage, Cornell voltage, Cornell product, S D +SV 4 , Manning, and R+S in any precordial lead had relatively higher sensitivity, especially S D +SV 4 criteria. Their combination could further increase sensitivity (43% vs 29% [S D +SV 4 ], P = 0.016). PTFV 1 was the only criterion that had significant diagnostic value for ECHO LAE (AUC, 0.68; 95% CI: 0.54‐0.73, P = 0.008). For middle‐aged hypertensive patients without evident cardiovascular diseases, S D +SV 4 had the highest sensitivity for the diagnosis of LVH and the combination of several ECG LVH criteria might further increase sensitivity. PTFV 1 had significant diagnostic value for ECHO LAE.
