Project no. 23685 · Status: Kapanmış · 2022
Summary
<p>Objective</p><p>Preventing hypertension in patients with a continuous flow ventricular assist device (CF-VAD) is</p><p>crucial for minimizing numerous complications, including pump thrombosis and cerebral hemorrhage.</p><p>Consequently, the objective of this study was to evaluate the dependability of noninvasive Vascular</p><p>Doppler blood pressure measurements by comparing them to invasive arterial pressure measurements.</p><p>Methods</p><p>The research involved 32 individuals aged 18 or above who received a left ventricular assist device</p><p>implant and were monitored using an invasive arterial pressure catheter in Ege University</p><p>Cardiovascular Department. The blood pressure of these patients was measured non-invasively with a</p><p>vascular hand Doppler device in the extremity where the invasive arterial monitoring was performed.</p><p>Pressure measurements were recorded twice daily for a period of 3 days in each participant.</p><p>Results</p><p>Of the patients, 96.9% were male. The mean patient age was 52.28. Heartmate-2 device was implanted</p><p>in 6.3% of the patients, the Heartmate-3 device was implanted in 84.4%, and the Heartware device</p><p>was implanted in 9.4%.</p><p>A comparison of the mean arterial pressure and Doppler measurement pressure is presented in Table 2.</p><p>The mean arterial pressure and Doppler pressure measurements were analyzed using Spearman’s</p><p>correlation analysis. Most of the correlations are above 0.75 and are considered good-to-excellent</p><p>correlations. (Table 3) When the systolic arterial pressure and blood pressure measurements with the</p><p>Doppler device were compared using Spearman correlation analysis, they were found to be below</p><p>0.75. (Table 5)</p><p>When subjected to Spearman correlation analysis and Wilcoxon Signed Rank Test, the measurements</p><p>obtained using the Doppler device were found to yield results that were closer to the invasive mean</p><p>arterial pressure.(Table 4,Table 6)</p><p>Conclusion</p><p>For continuous-flow VAD patients, Doppler pressure correlates well with invasive Mean Arterial</p><p>Pressure. It is most appropriate to use Doppler pressure measurement as the standard non-invasive</p><p>Blood Pressure measurement method for VAD patients.</p>
