Purpose: We aimed to investigate if baseline NTproBNP and clinical variables, predict incident atrial fibrillation (AF) in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI). Methods: From a prospective registry, we assessed 984 PPCI patients. In univariate and multivariate regression analysis, we investigated the association of NTproBNP level determined just prior to PPCI, peri-procedural systolic and diastolic blood pressure, infarct size (maximum CK), gender and age, with the incidence of AF. A Kaplan-Meier curve with quartiles of NTproBNP was computed with a log-rank test to assess for significance of differences. Results: NTproBNP was higher (1297 pg/ml versus 570 pg/ml) in patients with versus without incident AF. In univariate analysis, NTproBNP was significantly associated with incident AF (OR 1,11, 95% CI 1,03-1,21, P=0,009). In multivariate analysis, age was the strongest predictor of incident AF (highest quartiles versus lowest quartile OR 7,04, 95% CI 2,77 -17,87, P<0,001). NTproBNP (OR 1,09, 95% CI 1,00 -1,20, P=0,049), systolic blood pressure (OR 0,98, 95% CI 0,97 -1,00, P=0,021) and infarct size (OR 1,18, 95% CI 1,04 -1,33, P=0,01) were also independently associated with incident AF. Gender, target lesion vessel and diastolic blood pressure were not associated with incident AF. Kaplan-Meier curves (Figure 1) depict that higher NTproBNP quartile is significantly (P=0,001) associated with incident AF. Figure 1. Kaplan-Meier curves Conclusion: Age is strongly predictive for incident AF in STEMI patients undergoing PPCI. NTproBNP and infarct size are also independent predictors of incident AF, whereas peri-procedural systolic blood pressure is inversely related to incident AF.

This study was performed to determine the relation between inducible sustained ventricular tachycardia (ISVT) by programmed electrical stimulation and angiographic, clinical and echographic data in patients with coronary artery disease. The aim of this study was to explore if these inducible arrhythmias are associated with any specific "arrhythmogenic" pattern of coronary artery disease. 129 consecutive patients with coronary artery disease and ISVT were evaluated by left ventriculography and coronary arteriography by standard techniques. The mean age of the patients was 46 years with a range of 21 to 72 years, 74% of them were males. A significant stenosis of the main left coronary artery (>50%) appeared to be more frequent in arrhythmia patients (31%). Also proximal left anterior descending artery stenosis was more frequent in in the arrhythmia patients (48%). "Main left equivalent" lesions, defined as a significant stenosis of the proximal left anterior descending artery and the proximal left circumflex artery was significantly more frequent among the arrhythmia patients (51%). Using the quantitive wall motion analysis, a strong relationship was found between the number of abnormally contracting segments and the presence of inducible sustained ventricular tachycardia. The results of the present study suggest that ISVT in patients with coronary artery disease are more frequently associated with lesions of the main left coronary artery or the proximal left anterior descending artery.

Bu çalışmanın amacı, kedilerin alt idrar yolu hastalıklarının direkt radyografi, ultrasonografi, kontrast sistografi ile retrospektif olarak değerlendirilmesi ve her hastalık için en uygun görüntüleme metodunun ortaya konmasıdır. Çalışmada farklı yaş, cinsiyet ve ırkta 134 kedi, alt idrar yolu hastalıklarının bir veya daha fazla klinik bulgusu ile getirilmiştir. Kedilerin tamamı radyografi ve ultrasonografi ile değerlendirilmiştir. Alt idrar yolu hastalığı olarak sistitis (n=20), idrar kristalleri (n=35), sistitisle birlikte seyreden idrar kristalleri (n=51), idrar taşları (n=6), idrar kesesi polipleri (n=8), idrar kesesi içindeki kan pıhtıları (n=9), idrar kesesi rupturu (n=1) ve idiopatik obstrüksiyonlar (n=4) belirlenmiştir. İdrar kesesinin opak taşları direkt abdominal radyografi ile kolaylıkla tespit edilmiştir. Kronik sistitis ve idrar kesesi rupturunun belirlenmesinde kontrast sistografi; sistitis, taş, kristal, polip ve kan pıhtılarının teşhisi için ultrasonografi kullanılmıştır. Çalışmada, alt idrar yollarının değerlendirilmesinde ultrasonografinin yeterli bir görüntüleme metodu olduğu doğrulanmış, ancak radyografi ve kontrast sistografinin de idrar taşı, idrar rupturu, şüpheli idrar yolu obstrüksiyonu ve ultrasonografi ile belirlenemeyen kronik sistitis teşhisinde yararlı olduğu görülmüştür
