Advanced age, heart rate, systolic blood pressure, diabetes mellitus, recurrent or persistent pain. The prognosis is worse in diabetics and elderly patients, especially in presence of renal failure, sinus tachycardia and evident haemodynamic impairment (hypotension, pulmonary oedema, etc.) (grade 3-4 of Killip classification) (Wiviott et al, 2006).

Assessing sodium concentration is of clinical relevance as low urine sodium concentration may indicate dehydration, while a relatively high urine sodium concentration suggests acute renal failure. Lvova and coworkers (2009) proposed an E-tongue composed of chemical sensors to detect urinary system dysfunctions and creatinine levels. The electrochemical system was composed of miniaturized metallic sensors and ISEs with PVC solvent polymeric membranes. The device enabled the correct classification of urine samples from healthy volunteers, according to creatinine levels and to predict the creatinine content of urine.
