RESUMO

Resumo Fundamento A patologia subjacente da ectasia da artéria coronária (EC) isolada não foi totalmente elucidada. Objetivo Nosso objetivo foi examinar a relação entre o índice de inflamação imune sistêmica (Sıı), que corresponde à multiplicação da razão neutrófilos-linfócitos (RNL) e as contagens de plaquetas, e EC isolada. Método A população do estudo retrospectivo incluiu 200 pacientes com EC isolada, 200 consecutivos com doença arterial coronariana obstrutiva e 200 consecutivos com angiografia coronária normal. Um valor de p bicaudal <0,05 foi considerado significativo. Resultados Sıı, RNL, razão plaqueta-linfócito (RPL) e razão monócito-colesterol de lipoproteína de alta densidade (MHR) foram significativamente maiores no grupo EC em comparação com os outros grupos (todos p<0,001). Na análise multivariada, Sıı (p<0,001, OR = 1,005, IC 95% =1,004-1,005) foi considerado um preditor independente de EC isolada. Na análise da curva Receiver Operating Characteristic (ROC), Sıı teve uma área sob a curva maior em comparação com RNL, RPL e MHR. O valor de Sıı >517,35 tem 79% de sensibilidade, 76% de especificidade para a predição do EC [AUC: 0,832, (p<0,001)]. Sıı teve correlação significativa com o número de artérias coronárias ectásicas e classificação de Markis (r: 0,214 p=0,002; r:-0,195, p=0,006, respectivamente). Conclusão Até onde sabemos, este é o primeiro estudo em que Sıı foi significativamente associado à presença isolada de EC e gravidade anatômica.


Abstract Background The underlying pathology of isolated coronary artery ectasia (CE) has not been fully elucidated. Objective We aimed to examine the relationship between the systemic immune inflammation index (Sıı), which corresponds to the multiplying of the neutrophil-to-lymphocyte ratio (NLR) and the platelet counts, and isolated CE. Method The retrospective study population included 200 patients with isolated CE, 200 consecutive with obstructive coronary artery disease, and 200 consecutive with a normal coronary artery angiogram. A 2-sided p-value of <0.05 was considered significant. Results Sıı, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-high density lipoprotein cholesterol ratio (MHR) were significantly higher in the CE group compared with the other groups (all p<0.001). In multivariate analysis, Sıı (p<0.001, OR = 1.005, 95% CI =1.004-1.005) was found to be an independent predictor of isolated CE. In Receiver Operating Characteristic curve analysis, Sıı had a higher Area Under the Curve than NLR, PLR, and MHR. Sıı value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sıı had a significant correlation with the number of ectatic coronary arteries and Markis classification (r:0.214 p=0.002; r:-0.195, p=0.006, respectively). Conclusion To the best of our knowledge, this is the first study that Sıı was significantly associated with isolated CE presence and anatomical severity.

RESUMO

There is a lack of evidence regarding the short-term predictive value of serum albumin to creatinine ratio (sACR) in patients with ST-segment elevation myocardial infarction (STEMI). This study aims to investigate the relationship between sACR and short-term outcomes in these patients. We retrospectively enrolled 3057 patients with STEMI who underwent primary percutaneous coronary interventions (PCI) (median age was 58 years, and 74.3% were male). In-hospital mortality occurred in 114 (3.7%) patients. Contrast-induced nephropathy (CIN) was reported in 381 (12.4%) patients. During a 30-day follow-up, stent thrombosis (ST) occurred in 28 (.9%) patients and 30-day death in 147 (4.8%) patients. Multivariable logistic regression analysis reported that sACR was inversely associated with 30-day mortality (adjusted odds ratio (aOR): .51, 95% confidence interval (CI) .31-.82, P < .001). The sACR was also inversely associated with in-hospital mortality (aOR: .71, 95% CI .56-.90, P = .009), CIN (aOR: .60, 95% CI .52-.68, P < .001), congestive heart failure (CHF) (aOR: .64, 95% CI .47-.87, P = .007), and ST (aOR .61, 95% CI .41-.92, P = .001) at 30 days. Our findings suggest that sACR is inversely associated with short-term clinical outcomes in patients with STEMI after PCI.

RESUMO

Narrowing of the iliac artery is a common presentation of systemic atherosclerosis. With the recent development of invasive techniques, angioplasty and stenting offer excellent results for fixing limb ischemia of aorto-iliac arteries. However, despite novel interventional approaches and constantly increasing experience, complications such as distal embolization, stent migration, acute or subacute iliac artery occlusion, dissection, and perforations are still challenging. Early restenosis and/or reocclusion of peripheral artery stents is uncommon, but the risk of delayed or late thrombotic occlusions of iliac artery stents is unclear. Although with questionable impact, hypercoagulable state or patient noncompliance may contribute to the pathogenesis of stent thrombosis. We describe a patient with terminal renal cell carcinoma who developed late iliac artery stent thrombosis despite dual chronic antiplatelet therapy with aspirin and clopidogrel.
