Blood Pressure and Body Weight Have Different Effects on Pulse Wave Velocity and Cardiac Mass in Children.
<p><strong>Background: </strong>High blood pressure (BP) and excess weight can lead to early cardiovascular organ damage already in children. Carotid-femoral pulse wave velocity (cf-PWV) is the non-invasive gold standard method for assessing aortic stiffness, while carotid-radial PWV (cr-PWV) provides information on the distensibility of the upper limb arteries. The aim of this study was to evaluate the relationship of BP and BMI z-scores with arterial stiffness and left ventricular mass index (LVMI) in a pediatric population.</p> <p><strong>Methods: </strong>In 343 children (57.7% males; age ± SD 11.7 ± 2.9 years), systolic (SBP) and diastolic (DBP) BP, BMI, cf-PWV, cr-PWV and LVMI were measured. A multiple linear regression model was used to assess the impact of BMI and SBP (or DBP) z-scores on cf-PWV, cr-PWV and LVMI.</p> <p><strong>Results: </strong>About 21% of children were normal weight, 34% were overweight and 45% obese. Adjusted for possible confounders, SBP and DBP z-scores were significantly associated with cf-PWV (<em>p</em> < 0.001), while only DBP z-scores were related to cr-PWV (<em>p</em> < 0.01). BMI was neither associated with cf-PWV nor with cr-PWV values but was a strong predictor of LVMI (<0.001), whereas cardiac mass and BP z-scores were not related.</p> <p><strong>Conclusions: </strong>Our study suggests that, in children, elevated BP values and excess weight may have different effects on the heart and the vessels in causing early cardiovascular alterations.</p> <div class="pg-extension"> </div>
Prognostic Relevance of Left Ventricular Thrombus Motility: Assessment by Pulsed Wave Tissue Doppler Imaging
<p>Raw data.</p> <p>Abstract<br> Pulsed wave tissue Doppler imaging (PW-TDI) easily detects motion of cardiac structures. Hence, PW-TDI could be of value for<br> assessing potentially cardioembolic masses. We sought to evaluate the prognostic value of left ventricular (LV) thrombus mobility<br> assessed by PW-TDI. In 83 consecutive patients with echocardiographically detected LV thrombi, PW-TDI echocardiographic<br> study was performed. At 1-year follow-up, the composite of major adverse cardiovascular events (MACE) defined as all-cause<br> mortality plus hospitalizations for stroke/systemic embolism was evaluated. Seventy-two patients (77.1 + 13.1 year/old,<br> 32 males) were studied. All thrombi were located at the LV apex. At 1-year follow-up, 17 cardioembolic events occurred. By<br> univariable Cox analysis, variables associated with MACE were heart rate (hazard ratio: 1.02, 95% CI: 1.00-1.05; P ¼ .03), thrombi<br> with mobile free edge (hazard ratio: 3.25, 95% CI: 1.25-8.44; P ¼ .01), hypoechoic thrombi (hazard ratio: 2.86, 95% CI: 1.10-7.42;<br> P ¼ .03), and mass peak antegrade velocity (Va) 10 cm/s (hazard ratio: 8.79, 95% CI: 2.00-38.5; P ¼ .004). By multivariable<br> analysis, thrombi with mobile free edge (hazard ratio: 3.54, 95% CI: 1.23-10.2; P ¼ .02), and mass peak Va 10 cm/s (hazard ratio:<br> 7.97, 95% CI: 1.60-39.6; P ¼ .01) retained statistical significance. Mass peak Va 10 cm/s predicted the composite end point with<br> 94% sensitivity and 85% specificity (area under the curve ¼ 0.86). In conclusion, PW-TDI allows objective prognostication of LV<br> thrombi embolic risk.</p>
Non-Invasive assessment of arterial stiffness: pulse wave velocity, pulse wave analysis and carotid cross sectional distensibility. Comparison between methods
<p>Background: The stiffening of large elastic arteries is currently estimated in research and clinical practice by propagative and non-propagative models, as well as parameters derived from aortic pulse waveform analysis. Methods: Common carotid compliance and distensibility were measured by simultaneously recording the diameter and pressure changes during the cardiac cycle. The aortic and upper arm arterial distensibility was estimated by measuring carotid–femoral and carotid–radial pulse wave velocity (PWV), respectively. The augmentation index and blood pressure amplification were derived from the analysis of central pulse waveforms, recorded by applanation tonometry directly from the common carotid artery. Results: 75 volunteers were enrolled in this study (50 females, average age 53.5 years). A significant inverse correlation was found between carotid distensibility and carotid–femoral PWV (r = −0.75; p < 0.001), augmentation index (r = −0.63; p < 0.001) and central pulse pressure (r = −0.59; p < 0.001). A strong correlation was found also between the total slope of the diameter/pressure rate carotid curves and aortic distensibility, quantified from the inverse of the square of carotid–femoral PWV (r = 0.67). No correlation was found between carotid distensibility and carotid–radial PWV. Conclusions: This study showed a close correlation between carotid–femoral PWV, evaluating aortic stiffness by using the propagative method, and local carotid cross-sectional distensibility.</p>
