Systolic inter-arm pressure difference (SIAD) is considered as cardiovascular risk. We aimed to ascertain whether the presence of(SIAD) is associated with impaired left ventricular (LV) functions or not. Methods: Blood pressure (BP) was measured on both arms of 81 participants, echocardiographic parameters of LV functions; ejection fraction, mitral E, A, e`, a`and tricuspid regurgitant velocities, left atrial volume index, E/A and E/e` ratio, LV stiffness index and myocardial performance index (MPI) were measured, and global longitudinal strain (GLS) was assessed. Results: Higher SIAD level had good positive correlations with age, body mass index (BMI), duration of hypertension (HTN), MPI, and LV end‑systolic volume. SIAD had good negative correlations with mitral E wave velocity, E/A ratio, e` and s` wave velocities, and with the average GLS. Impaired LV average GLS is independently associated with: Years from HTN discovery followed by BMI, gender, and age. Conclusion: BP reading in both arms on the first visit is not sufficient; hypertensive patients need evaluation of the SIAD on follow up. We need to consider the SIAD on risk stratification and BP control. This will be simple to follow in primary care and areas with low resources.
