Zusammenfassung
Ziel
Ziel ist die Deskription populationsbasierter geschlechts- und altersstratifizierter Daten der karotidalen Intima-Media-Dicke (CIMT)-Verteilung sowie der Vergleich fixer Cut-off- und Perzentilenwerte für Personen mit und ohne koronare Herzerkrankung (KHK) und die Deskription von CIMT-Perzentilen.
Methoden
Zwischen 2000 und 2003 wurden 4.814 Teilnehmer zwischen 45 und 75 Jahren in die Heinz Nixdorf Recall Studie (HNR) rekrutiert. Die Ultraschalluntersuchung wurde an den extrakraniellen Gefäßen durchgeführt und die CIMT manuell 1 cm proximal des Bulbus der Arteria carotis communis (ACC) auf beiden Seiten gemessen und der Mittelwert herangezogen.
Ergebnisse
Die CIMT konnte für 1.749 Männer und 1.802 Frauen ohne und 177 Männer und 50 Frauen mit vorbekannter KHK gemessen werden. Die mittlere CIMT war bei Männern höher als bei Frauen (Männer 0,71±0,14 mm vs. Frauen 0,65±0,11 mm, p<0,0001) und auch bei Probanden mit KHK gegenüber denen ohne KHK erhöht (Männer mit und ohne KHK: 0,76±0,14 mm und 0,70±0,14 mm, p<0,0001; Frauen mit und ohne KHK: 0,73±0,15 mm und 0,64±0,11 mm, p<0,0001). Bei Männern stieg die mittlere CIMT von 0,62±0,10 mm in der jüngsten (45–49 Jahre) bis auf 0,79±0,13 mm in der ältesten Altersgruppe (≥70 Jahre), bei Frauen von 0,57±0,08 mm bis auf 0,71±0,12 mm (p<0,0001 für beide).
Schlussfolgerung
Wir berichten über CIMT-Verteilungen mit hoher Übereinstimmung verglichen mit internationalen Studien. Besonders bei älteren Teilnehmern beobachteten wir allerdings niedrigere CIMT-Werte, was auf den Ausschluss karotidaler Plaque-Formationen bei der CIMT-Messung zurückgeführt werden kann.
Abstract
Purpose
The aim of this study was to introduce population-based sex and age-stratified distributions of carotid intima media thickness (CIMT), to compare fixed cut-off and percentile values for subjects with and without known coronary heart disease (CHD) and to describe CIMT percentiles.
Methods
Between 2000 and 2003, a total of 4,814 subjects aged 45–75 years were recruited into the Heinz Nixdorf recall study (HNR). Ultrasound examination of extracranial arteries was performed and the CIMT was measured manually over a distance of 1 cm proximal to the bulb in the common carotid artery (CCA). Both sides were measured and the average of the right and left artery were calculated (mean CIMT).
Results
The CIMT was measured for 1,749 men and 1,802 women without prevalent CHD and 177 men and 50 women with prevalent CHD. Mean CIMT values were higher in men compared to women (men 0.71 ± 0.14 mm vs. women 0.65 ± 0.11 mm, p ≤ 0.0001) and in subjects with CHD compared to those without (men with and without CHD: 0.76 ± 0.14 mm and 0.70 ± 0.14 mm, p ≤ 0.0001, respectively; women with and without CHD: 0.73 ± 0.15 mm and 0.64 ± 0.11 mm, p ≤ 0.0001, respectively). In men the mean CIMT increased from 0.62 ± 0.10 mm in the youngest (45–49 years old) up to 0.79 ± 0.13 mm in the highest age group (≥ 70 years) (0.57 ± 0.08 mm up to 0.71 ± 0.12 mm in women, p ≤ 0.0001 for both).
Conclusions
Compared to international studies similar CIMT distributions were found in this study using both continuous and percentile distributions. However, lower CIMT values were observed in older participants, which can be explained by exclusion of carotid plaque formation in CIMT measurements.
