Metabolik sendromlu hastalarda sol atriyal volüm indeksi'nin subklinik ateroskleroz ile ilişkisi3,4, 3,

Metabolik sendrom (MetS) ateroskleroza, sol ventrikül yapı ve fonksiyonlarında bozulmaya neden olur. Diyastolik disfonksiyon (DD) subklinik kardiyak hasarın erken dönem bulgusudur. Sol atriyal volüm DDun ciddiyetini ve süresini göstermede bir belirteç olarak kullanılabilir. Çalışmamızda, MetSlu hastalarda sol ventrikül DD ve derecesini, sol atriyal volüm indeksi (SAVİ) ile birlikte değerlendirdik ve bunun karotis intima media kalınlığı (KİMK) ile tespit edilen subklinik aterosklerozla ilişkisini araştırdık. Çalışmaya MetSlu 82 hasta alındı. Hastalar KİMK ölçümüne göre, KİMK≥1,0 mm olan 35 hasta grup 1, KİMK

Relation of left atrial volume index with subclinical atherosclerosis at patients with metabolic syndrome

Metabolic syndrome (MetS) increases the frequency of cardivovascular events by causing atherosclerosis and impairment at left ventricle structure and function. Diastolic dysfunction (DD) is an early finding of subclinical cardiac injury. Left atrial volume may be used as an indicator for demonstrating severity and duration of DD. With this study, we investigated the relationship between subclinical atherosclerosis ,evaluated by carotid intima-media thickness (CIMT) measurement and subclinical cardiac injury evaluated by diastolic functions and left atrial volume index (LAVI) in MetS patients. 82 patients with MetS were enrolled to the study. Patients were divided into 2 groups according to CIMT measurement: 35 patients with CIMT≥1.0 mm were at group 1 and 47 patients with CIMT
