ABSTRACT
INTRODUCTION: Contrast-induced nephropathy (CIN) is a common and severe complication in interventional cardiology. OBJECTIVE: The aim of our study was to compare the incidence of contrast-induced nephropathy in two accelerated hydration protocols: the first one by the serum bicarbonate and the second combining the serum bicarbonate and oral vitamin C. METHODS: This is a multicenter prospective, randomized study conducted between October 2012 and May 2013, including 160 patients. RESULTS: The mean age of our study population was 60.8±9.3 years (36-83 years). The two study groups were comparable in terms of cardiovascular risk factors, concomitant medication, and baseline serum creatinine. The CIN incidence was 6.3% in the vitamin C group and 10% in the control group (P=0.38). No significant difference was observed in terms of CIN incidence between the different subgroups analyzed. CONCLUSION: According to our study, ascorbic acid administered orally as part of an accelerated hydration protocol does not reduce the incidence of CIN.

The diagnosis of hypertrophic cardiomyopathy is usually established by echocardiography. Recently, there has been greatly increased use of cardiac magnetic resonance (CMR) because of its precise determination of myocardial anatomy and the depiction of myocardial fibrosis. In this review, we describe the role of echocardiography and magnetic resonance in the assessment of this complex disease. In conclusion, there is a complementarity between cardiovascular magnetic resonance imaging and echocardiography for the diagnosis and the management of HCM.
