Abstract

Aim: Although previous studies have shown a significant association between coronary risk factors or carotid atherosclerosis and valvular calcifications, there is conflicting evidence about which clinical cardiovascular risk factors are related to valvular calcifications.We aimed to evaluate the cardiovascular risk factors and carotid intima media thicknesses in patients with single and double valve calcifications in whom echocardiography has been performed prior to elective coronary angiography. Materials and Methods: 100 patients having double valve calcifications (aortic valve calcification and mitral annular calcification; 47 female and 53 male; mean age 68.1±8.7 years) and 90 patients having single valve calcification (aortic valve calcification; 29 female and 61 male; mean age 62.8±9.8 years) were enrolled into the study. All patients underwent transthoracic echocardiography, carotis ultrasonography and coronary angiography. Results: Age, female gender and hypertension were found to be significantly higher in patients with double valve calcifications (p=0.0001, 0.038 and 0.027; respectively). In means of hyperlipidemia, smoking, diabetes mellitus, body mass index, coronary artery disease and carotis intima media thickness, no significant difference was observed between the both groups. Age and female gender were found to be independent predictors in patients with double valve calcifications. Conclusion: These data have suggested that aortic and mitral valve calcifications may have different pathogenetic mechanisms and mitral annular calcification may also have some additional pathogenetic factors. Key words: Aortic Valve Calcification; Mitral Annular Calcification; Carotis Intima Media Thickness; Cardiovascular Risk Factors.

Tek Kapak ve Çift Kapak Kalsifikasyonlu Hastalarda Kardiyovasküler Risk Faktörleri ve Karotis İntima Media Kalınlığının Karşılaştırılması

Abstract

Amaç: Önceki çalışmalarda, kapak kalsifikasyonları ile koroner arter hastalığı veya karotid aterosklerotik hastalık arasındaki yakın ilişki gösterilmiş olmasına rağmen, hangi klinik kardiyovasküler risk faktörlerinin kapak kalsifikasyonları ile ilişkili olduğu hakkında çelişkiler mevcuttur. Bu çalışmada, elektif koroner anjiyografi öncesi ekokardiyografi yapılan tek kapak ve çift kapak kalsifikasyonlu hastalarda kardiyovasküler risk faktörlerini ve karotis intima media kalınlıklarını değerlendirmeyi amaçladık. Gereç ve Yöntem: Çalışmaya çift kapak kalsifikasyonu olan 100 hasta (aort kapak kalsifikasyonu ve mitral annüler kalsifikasyon; 47 kadın ve 53 erkek; ortalama yaş 68,1±8,7 yaş) ve tek kapak kalsifikasyonu olan 90 hasta (aort kapak kalsifikasyonu; 29 kadın ve 61 erkek; ortalama yaş 62,8±9,8 yaş) alındı. Tüm hastalara transtorasik ekokardiyografi, karotis ultrasonografi ve koroner anjiyografi yapıldı. Bulgular: Yaş, kadın cinsiyet ve hipertansiyon çift kapak kalsifikasyonu olan hastalarda anlamlı olarak daha yüksek bulundu (sırasıyla; p=0,0001, p=0,038 ve p=0,027). Her iki grup arasında hiperlipidemi, sigara içimi, diyabetes mellitus, vücut kitle indeksi, koroner arter hastalığı ve karotis intima media kalınlığı yönünden anlamlı farklılık bulunmadı. Çift kapak kalsifikasyonu olan hastalarda, yaş ve kadın cinsiyet bağımsız belirleyiciler olarak bulundu. Sonuç: Bu veriler, aort ve mitral kapak kalsifikasyonlarının farklı patojenik mekanizmaları olabileceğini ve mitral annüler kalsifikasyon gelişiminde ayrıca bazı ek faktörlerin rol oynayabileceğini düşündürmektedir. Anahtar kelimeler: Aort Kapak Kalsifikasyonu; Mitral Annüler Kalsifikasyon; Karotis İntima Media Kalınlığı; Kardiyovasküler Risk Faktörleri.
