Systemic Immune Inflammation Index is a Novel Marker in Predicting the Presence and Severity of Isolated Coronary Artery Ectasia. / O Índice de Inflamação Imune Sistêmica é um Novo Marcador na Previsão da Presença e Gravidade aa Ectasia Coronariana Isolada.

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 (Sii), 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: Sii, 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, Sii (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, Sii had a higher Area Under the Curve than NLR, PLR, and MHR. Sii value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sii 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 Sii was significantly associated with isolated CE presence and anatomical severity.

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 (Sii), 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: Sii, 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, Sii (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), Sii teve uma área sob a curva maior em comparação com RNL, RPL e MHR. O valor de Sii >517,35 tem 79% de sensibilidade, 76% de especificidade para a predição do EC [AUC: 0,832, (p<0,001)]. Sii 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 Sii foi significativamente associado à presença isolada de EC e gravidade anatômica.

Twist deformation for predicting postoperative left ventricular function in patients with mitral regurgitation: A speckle tracking echocardiography study.

PURPOSE: Postoperative LV dysfunction is associated with poor prognosis and increased mortality in patient with mitral regurgitation undergoing surgery. With this study, we aimed to investigate the predictive value of classic and speckle tracking echocardiographic (STE) LV deformational parameters for estimating postoperative LV dysfunction. METHODS: Fifty-nine asymptomatic patients with severe mitral regurgitation (MR) due to mitral valve prolapse, who had sinus rhythm and LV ejection fraction (EF) ≥50%, were included. Patients underwent comprehensive and speckle tracking echocardiographic examination before and 6 months after the surgical procedure. Patients were divided into two groups according to postoperative LV function: group A postoperative LV EF≥50% and group B postoperative LV EF<50%. RESULTS: Patients in group A were found to have higher LV twist (19.7±6.8° vs 11.9±4.2°; P<.001), LV global longitudinal peak strain (GLPS) (-21.7±4 vs -16.5±3.4%; P<.001), and circumferential strain (-19.5±5.2 vs -14.4±5.1%; P=.004) values but lower end-systolic diameter (ESD) (3.2±0.6 vs 4.1±0.9 cm; P<.001) when compared to group B. Multivariate logistic regression analysis revealed that GLPS, ESD, and twist were independent predictors of postoperative LV functions. In the ROC analysis, GLPS ≥18.4% and twist>14.4° predicted postoperative LVEF ≥50%. CONCLUSION: GLPS and twist measured by 2DSTE are predictors of LV preservation after surgery in severe MR. These parameters may also be used as prognostic predictors and optimal timing of operation in this patient population.

Coronary slow flow accompanying exertional blurred vision and effects of corticosteroids.

Background Various pathophysiological mechanisms such as microvascular and endothelial dysfunction, small vessel disease, diffuse atherosclerosis, and inflammation have been held responsible in the etiology of coronary slow flow. It is also thought to be a reflection of a systemic slow-flow phenomenon in the coronary arterial tree. Case Report A 44-year-old man presented with chest pain causing fatigue, together with blurred vision for the last 2 years, which disappeared after resting. He had used corticosteroid therapy for facial paralysis 1 month ago. Coronary slow flow was detected in all 3 major coronary arteries on coronary angiography. TIMI measurements for the left anterior descending artery, circumflex, and right coronary artery were 64, 72, and 55, respectively. In fundus fluorescein angiography, retinal vascularity was normal, the arm-to-retina circulation time was 21.8 s, and the arteriovenous transit time was 4.3 s. In the early arteriovenous phase, choroidal filling was long, with physiological patchy type. Diltiazem 90 mg/day and acetylsalicylic acid 100 mg/day were given. His chest pain and visual symptoms disappeared after medical treatment. Conclusions Physicians should be aware that glucocorticoids might cause an increase in the symptoms of coronary slow flow and some circulation problems, which might lead to systematic symptoms.

Relation of left atrial peak systolic strain with left ventricular diastolic dysfunction and brain natriuretic peptide level in patients presenting with ST-elevation myocardial infarction.

BACKGROUND: In patients presenting with ST-elevation myocardial infarction (STEMI), we investigated the relation of left atrial (LA) deformational parameters evaluated by two-dimensional speckle tracking imaging (2D-STI) with conventional echocardiographic diastolic dysfunction parameters and B-type natriuretic peptide (BNP) level. METHODS: Ninety STEMI patients who were treated with primary percutaneous coronary intervention (PCI) and 22 healthy control subjects were enrolled. STEMI patients had echocardiographic examination 48 hours after the PCI procedure and venous blood samples were drawn simultaneously. In addition to conventional echocardiographic parameters, LA strain curves were obtained for each patient. Average peak LA strain values during left ventricular (LV) systole (LAs-strain) were measured. RESULTS: BNP values were higher in MI patients compared to controls. Mean LAs-strain in control group was higher than MI group (30.6 ± 5.6% vs. 21.6 ± 6.6%; p = 0.001). LAs-strain had significant correlation with LVEF (r = 0.51, p = 0.001), also significant inverse correlations between LAs-strain and BNP level (r = -0.41, p = 0.001), E/Em (r = -0.30, p = 0.001), LA maximal volume (r = -0.41, p = 0.001), LA minimal volume (r = -0.50, p = 0.001) and LV end systolic volume (r = -0.37, p = 0.001) were detected. The cut off value of LAs-strain to predict BNP > 100 pg/ml was determined as 19.9% with 55.3% sensitivity and 77.2% specificity (p < 0.05 AUC:0.7). CONCLUSION: Our study showed that LAs-strain values decreased consistently with deteriorating systolic and diastolic function in STEMI patients treated with primary PCI. LA-s strain measurements may be helpful as a complimentary method to evaluate diastolic function in this patient population.
