BACKGROUND Chronic kidney disease is associated with increased risk of mortality. We examined the impact of moderate and severe renal insufficiency (RI) on short- and long-term mortality among unselected patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). METHODS From January 1, 2002 to December 31, 2010 all patients ...

BACKGROUND Renal impairment (RI) is associated with impaired prognosis in patients with coronary artery disease. Clinical and angiographic outcomes of patients undergoing percutaneous coronary intervention (PCI) with the use of drug-eluting stents (DES) in this patient population are not well established. METHODS We pooled individual data for 5,011 patients from 3 trials with the exclusive an...

BACKGROUND A close association exists between renal impairment (RI) and atrial fibrillation (AF) occurrence. Increased activity of the sympathetic nervous system (SNS) may contribute to the development of AF associated with RI. Renal denervation (RDN) decreases central sympathetic activity. OBJECTIVE The main objective of the study was to explore the effects of RDN on AF occurrence and its po...

BACKGROUND Detection of renal artery stenoses (RAS) by means of duplex Doppler ultrasound with direct scanning of the main renal arteries is subject to numerous limitations. Using semiquantitative analysis of the Doppler curve, which can be recorded from intrarenal arteries, it is possible to detect RAS unaffected by the problems of direct Doppler scanning of the renal arteries. METHODS Both ...

STUDY OBJECTIVES Neutrophilic inflammation is a major feature of COPD. Induced sputum is increasingly used to monitor inflammatory airway diseases. Although short-term repeatability of selected sputum markers has been extensively studied in several populations, data on the long-term repeatability of induced sputum markers in stable COPD are scant. DESIGN Sputum supernatant of 12 patients with...

From the coordinates transformation, we can see that only after i 1 (ri 1 (t)) is obtained can hi (ri (t )) be obtained. After we obtain hi (ri (t )) ; ~ ij (rj (t )) can be determined from (6). In other words, ~ ij (rj (t )) can not be determined until i 1 (ri 1 (t)) is obtained. However, from the iterative procedure in the main result of [1], we can see that function i 1 (ri 1 (t)) is obtaine...

Anti-peptide antibodies that distinguish between the rat brain sodium channel subtypes referred to as RI and RII were prepared and used to determine their relative expression in nerve and muscle tissues. Sodium channels purified from rat brain are approximately 18% RI and 80% RII. In brain, the RII subtype is preferentially expressed with RI/RII ratios ranging from 0.07 in the hippocampus to 0....

BACKGROUND Chronic kidney disease (CKD) is a growing public health problem and end stage renal disease (ESRD) represents a large human and economic burden. It is important to identify patients at high risk of ESRD. In order to determine whether renal Doppler resistive index (RI) may discriminate those patients, we analyzed whether RI was associated with identified prognosis factors of CKD, in p...
