Key Takeaways

This cross-sectional study was undertaken to determine the prevalence of left ventricular hypertrophy (LVH) among elderly primary care patients with long-standing asymptomatic hypertension. Also, in this specific patient group, the diagnostic worth of ECG as a screening instrument in LVH identification, relative to echocardiography, was assessed. This inquiry was performed in five general practices in the south-east of the Netherlands, and involved patients (n = 422) with primary care-treated hypertension, aged between 60 and 85 years, without known heart failure. Findings demonstrated a high prevalence of previously undetected LVH, which rose with age, in asymptomatic primary care patients with long-standing hypertension. In this patient population, the inadequacy of ECG for detecting LVH was found. More awareness for the optimal regulation of hypertension and compliance to therapy could potentially be created by early detection of LVH. Thus, experts suggested considering echocardiography as a screening tool for the detection of LVH in this patient group.
