SCORE Kardiyovasküler Risk Puanlama Sistemi ile Non-dipper Hipertansiyon Arasındaki İlişki

Amaç: Non-dipper kan basıncının (KB) uç organ hasarı ve ölümcül - ölümcül olmayan kardiyovasküler hastalıklarla (KVH) anlamlı şekilde ilişkili olduğu gösterilmiştir. Kardiyovasküler (KV) olay riskinde artış bulunan bireylerde sistematik KV risk değerlendirmesi önerilir. SCORE risk sistemi, ilk ölümcül aterosklerotik olayın 10 yıllık riskini değerlendirir. Bu çalışmanın amacı hipertansiyon (HT)hastalarında non-dipper KB ile SCORE risk sistemi arasındaki bir ilişki olup olmadığının araştırılmasıdır. Yöntemler: Bu çalışma retrospektif bir çalışmadır ve esansiyel HT tanısı konulan ardışık 213 hastayı içermektedir. Non-dipper ve dipper hasta grupları 24 saatlik ambulatuar kan basıncı izlemine (AKBİ) göre belirlendi. SCORE sistemine göre yaş, cinsiyet, sigara kullanımı, sistolik kan basıncı (SKB) ve total kolesterol (TK) gibi risk faktörleri kullanılarak 10 yıllık ölümcül KV olay riski hesaplandı. Bulgular: Non-dipper HT hasta grubunda SCORE risk sistemi anlamlı olarak yüksek saptandı (p=0.017). Ayrıca sigara içme alışkanlığı sıklığı ve TK değerleri non-dipper HT’li hasta grubunda anlamlı olarak daha yüksek saptandı. Diğer demografik, klinik ve laboratuvar parametreler iki grup arasında benzerdi. SCORE risk oranı ile gece sistolik ve diyastolik KB’leri arasında orta derecede olmasına rağmen anlamlı pozitif korelasyon izlendi (r = 0.354, p < 0.001; r =0.339, p<0.001; sırasıyla) Sonuç: Bu çalışmada ilk defa non-dipper HT ile SCORE risk sistemi arasında önemli bir ilişki olduğu gösterilmiştir. SCORE risk sistemi ile hesaplanan 10 yıllık fatal KV olay ihtimalinin non-dipper hasta grubunda daha yüksek saptanması, esansiyel HT tanılı hastaların AKBİ ile takibinin önemini ortaya çıkarmıştır

Monocyte-to-HDL-cholesterol ratio is associated with Ascending Aorta Dilatation in Patients with Bicuspid Aortic Valve

Background: The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the patients with bicuspid aortic valve. Methods: The study population included totally 347 patients with bicuspid aortic valve.169 patients with aortic dilatation (ascending aorta diameter 65 4.0 cm) and 178 patients with no aortic dilatation. Echocardiographic and laboratory measurement was done and compared between groups. Results: The mean age of the participants was 44.7 \ub1 15.4 years and average ascending aorta diameter was 3.2 \ub1 0.3 cm in dilatation negative group and 4.4 \ub1 0.4 cm in positive group. MHR was significantly increased in in patients with aortic dilatation. MHR and uric acid level was independently associated with the presence of aortic dilatation in the patients with bicuspid aortic valve. Conclusion: We found a significant relationship between MHR and aortic dilatation in the patients with bicuspid aortic valve

Does the cardiovascular drug levosimendan prevent iodinated contrast medium nephrotoxicity with glycerol aggravation in rats?

Background We investigated whether levosimendan prevents contrast medium nephrotoxicity with glycerol aggravation in rats. Methods Forty-eight Wistar albino rats were assigned to eight groups (n = 6 x 8). No medication was administered to group I (controls); glycerol (intramuscular injection of 25% glycerol, 10 mL/kg) group II; intravenous iohexol 10 mL/kg to group III; glycerol and iohexol to group IV; iohexol and intraperitoneal levosimendan 0.25 mg/kg to group V; glycerol, iohexol, and levosimendan 0.25 mg/kg to group VI; iohexol and levosimendan 0.5 mg/kg to group VII; and glycerol, iohexol, and levosimendan 0.5 mg/kg to group VIII. One-day water withdrawal and glycerol injection prompted renal damage; iohexol encouraged nephrotoxicity; levosimendan was administered 30 min after glycerol injection and continued on days 2, 3, and 4. The experiment was completed on day 5. Serum blood urea nitrogen (BUN) and creatinine levels, superoxide dismutase (SOD) activity, glutathione (GSH), malondialdehyde (MDA) levels, tumour necrosis factor-alpha (TNF-alpha), nuclear factor kappa ss (NFK-ss), interleukin 6 (IL-6), and histopathological marks were assessed. One-way analysis of variance and Duncan's multiple comparison tests were used. Results Levosimendan changed serum BUN (p = 0.012) and creatinine (p = 0.018), SOD (p = 0.026), GSH (p = 0.012), and MDA (p = 0.011). Levosimendan significantly downregulated TNF-alpha (p = 0.022), NFK-ss (p = 0.008), and IL-6 (p = 0.033). Histopathological marks of hyaline and haemorrhagic cast were improved in levosimendan-injected groups. Conclusion Levosimendan showed nephroprotective properties due to its vasodilator, oxidative distress decreasing and inflammatory cytokine preventing belongings
