“…TTE reflected invasive measurement of coronary flow velocity and CFVR accurately, and the agreement between the two methods was 0.97 for averaged diastolic and systolic peak velocities, 0.98 for diastolic peak velocity and 0.97 for CFVR. A very good correlation was observed between TTE and intracoronary Doppler guide wire not only for the LAD (Caiati et al, 1999a(Caiati et al, , 1998bLethen et al, 2003) but for the PDA as well (Ueno et al, 2002b). The correlation ranging from 0.79 to 0.97 has been reported for noninvasive techniques compared with invasive ones in cases of decision-making process (Hozumi et al, 1998a(Hozumi et al, , 1998bCaiati et al, 1999aCaiati et al, , 1998b) and intracoronary intervention (Lethen et al, 2003).…”

Thus, TTE can be used as a possible substitute of the invasive method for correct clinical measurement of CFVR, particularly in the LAD.…”

“…Transthoracic measurements of coronary flow velocity are proved to be highly reproducible and correlate with invasive measurements and measurements with positron emission tomography (Hozumi et al, 1998a;Caiati et al, 1999a, 1999b, Lethen et al, 2003Ueno et al, 2002b). The measurements can include assessment of peak velocity, time velocity integral, and mean velocity in systole and diastole ( fig.…”

“…Unlike intracoronary Doppler studies with the guide wire or guiding catheter, the influence of which on the vascular endothelium and coronary flow dynamics is unpredictable and may be a cause of high rate of impaired CFVR after balloon angioplasty or stenting (50% and 30%, respectively) even in the absence of any residual angiographic stenosis, TTE, being a non-invasive technique, is deprived of this effect, and can more accurately reflect changes of coronary flow. In the study including 53 patients, coronary angiography and CFVR detection were performed 6 months after PTCA of the LAD (Lethen et al, 2003). The investigators observed CFVR to significantly differ in the groups with and without restenosis, and CFVR with the cut-off value <2.0 demonstrated 89% sensitivity and 90% specificity for predicting Fig.…”

“…adenosine or dipyridamole) infusion is difficult to quantify accurately using echo Doppler, the ratio between hyperemic and baseline coronary blood flow velocity provides a good measure of endothelial function. CFR evaluated by transthoracic Doppler echocardiography corresponds to invasively measured CFR using intracoronary Doppler guidewire technique (43,44).…”

The endothelium, the inner layer of vessels, represents a huge organ, an important regulator and mediator of vasoactive factors. A number of common diseases including preeclampsia, hypertension, coronary heart disease and diabetes have been linked to poor endothelial function. Tests have been developed to measure endothelial function, but have not been suitable for population-based studies until they became noninvasive. Ultrasound imaging of the vessel diameter and the blood velocity has opened that door. The techniques are used to assess vascular distension and increased flow velocity as a response to reactive hyperemia after arterial occusion or administration of different drugs. Here we discuss the background, describe the techniques currently in use and their potential application in epidemiological studies.

Objective. Accelerated atherosclerosis is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Altered coronary microvascular function may act as a marker of changes that predispose to the development of significant coronary vascular disease. The purpose of this study was to compare coronary flow reserve (CFR) in a group of premenopausal women with SLE and a group of age-, sex-, and race-matched healthy control subjects.Methods. Coronary flow velocity in 18 premenopausal women with SLE (mean ؎ SD age 29.4 ؎ 5.9 years) and 19 matched healthy controls (mean ؎ SD age 28.2 ؎ 4.3 years) was assessed by transthoracic Doppler echocardiography after an overnight fast. The CFR was calculated as the ratio of hyperemic to baseline coronary blood flow velocity in the left anterior descending coronary artery. Hyperemia was induced by intravenous administration of adenosine triphosphate.Results. The mean ؎ SD duration of SLE was 8.2 ؎ 7.2 years (range 0.25-25 years), and the mean ؎ SD score on the Systemic Lupus Erythematosus Disease Activity Index was 11.0 ؎ 5.3 (range 4.0-21.0). Adequate recordings of flow velocity in the left anterior descending artery under both conditions were obtained using an ultrasound procedure in all study subjects. CFR was significantly lower in SLE patients as compared with control subjects (mean ؎ SD 3.4 ؎ 0.8 versus 4.5 ؎ 0.5; P < 0.0001).Conclusion. These findings provide evidence that coronary vasomotor function is impaired in patients with SLE and support the notion that many of these young patients have subclinical coronary artery disease.
