“…In addition other toxic effects include myocardial ischemia, systolic or diastolic myocardial dysfunction, cardiomyopathy, chronic heart failure, arterial or pulmonary hypertension, strokes, pericarditis, arrhythmias, thromboembolic disease, and others, extremely adversely affecting the prognosis of these patients (Łacko et al, 2002; Adão et al, 2013; Truong et al, 2014).
