Serum C-reactive protein (CRP)/albumin ratio (CAR) is demonstrated as a more precise marker in determining the prognosis of critical diseases than albumin and CRP levels, separately. Recently, inflammatory biomarkers are increasingly used for both screening and prognosis of coronary artery disease (CAD). As an ischemia-dependent risk index, CAR is an independent marker of in-hospital and long-term all-cause mortality in ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention. The results indicate that CAR is a more effective prognostic marker than either CRP or albumin.

Contrast-induced nephropathy (CIN) is a leading cause of morbidity and mortality in patients undergoing percutaneous coronary intervention (PCI). Chronic total occlusions (CTO) are frequently observed among patients undergoing coronary angiography.
A total of 128 CTO patients were included. Mehran score, lesion characteristics, interventional procedure, serological specimens and devices were recorded. The first group was administered with 1 ml · kg−1 · h−1 saline (0.9% NaCl) infusion that started 12 h before the procedure and continued 12 h post procedure as recommended by the guidelines. The second group was administered with saline infusion of 12 ml · kg−1 · h−1 only during CTO-PCI procedure, which is called as intensive infusion.
CIN development was similar in two groups (four patients in standard hydration group and five patients in intensive hydration group). The amount of saline was significantly higher in the standard group (1,767 ± 192.2 vs. 1,043.6 ± 375; p < 0.001). Patients with higher creatinine levels prior to PCI had a higher rate of CIN development after procedure. Interestingly, age, left ventricular ejection fraction, and diabetes mellitus independently predicted CIN.
Intensive hydration administration appears to be an effective and cost-effective method in CTO-PCI patients, especially in patients without left ventricular function failure.

Background and aims
The etiology and pathophysiology of coronary artery ectasia (CAE) has not been fully elucidated. A rapid rise in plasma copeptin has been observed in cardiovascular diseases, stroke, sepsis, and shock. This increase has diagnostic and prognostic value. The aim of this study was to investigate whether copeptin has a relationship with CAE.
This observational prospective study was carried out between October 2012 and March 2013 in the cardiology catheter laboratory with the inclusion of 44 subjects with a diagnosis of CAE and 44 age- and gender-matched individuals with normal coronary arteries. Blood samples obtained from the patients were stored at −70 °C until analysis and copeptin levels in sera were measured by ELISA.
This study comprised 88 study participants, among whom 44 were patients meeting ectasia criteria [mean age: 58.0 ± 11.5 years; 59% (n = 26) male], and 44 were control subjects with angiographically normal coronary anatomy [mean age: 49.2 ± 10.1 years; 30% (n = 13) male]. Copeptin levels were similar between the groups (p > 0.05). In addition, there was no correlation between copeptin levels and CAE.
In this study, it is examined that copeptin levels were not elevated in CAE patients.
