Abstract
The determination of myocardial viability has been considered a fundamental tool, mainly for patients with significant coronary disease and left ventricular dysfunction. In this scenario, it is believed that the cardiomyocytes have suffered a process of adapting to an altered physiological state that is potentially reversible.Echocardiography/cardiac ultrasound is a diagnostic method that can determine the different parameters of cardiac function. However, despite its usefulness having been demonstrated in various studies, there is still a level of uncertainty of the role of this diagnostic method in comparison with that of nuclear medicine or nuclear magnetic resonance in clinical practice.The aim of this review is to reflect on the physiological basis of myocardial viability, to discuss the importance of this widely available diagnostic method, and to summarise the most relevant and useful results in order to make decisions and optimise the management of the patients.The pathophysiological and clinical concept of myocardial viability is valid, and the searches for perfecting traditional methods, as well as the new technological developments allow its use for the optimisation of therapeutic strategies.
