Efficacy of Esmolol in the Identification of Cardiovascular Disorders by Cirrhosis, Diabetes Mellitus and Cardiotoxic Treatments

The purpose of this study is to assess the superiority of esmolol echocardiography over conventional echocardiography in the diagnosis of subclinical myocardial involvement associated with diabetes mellitus 2, cirrhosis and antineoplastic treatments.

After being informed about the study and potential risks, all patients giving written informed consent will undergo a 10 days screening period to determine eligibility for study entry. At Baseline, patients who meet the eligibility requirements will be allocate in one of the 4 cohorts according to their medical conditions.

Trial design consists in a Screening period, Baseline, and 6 additional visits until Month-36.

All patients will undergo to a conventional echocardiography and echocardiography with esmolol administration at Baseline. This procedure will be performed at the following visits according their cohort.

Other complementary procedures will be the collection of blood samples to determine biomarkers, as well as hematology and biochemistry, vital signs and another explorations.

Eligibility Criteria:
Inclusion Criteria:

1. Age ≥ 18 years.
2. Absence of previous heart disease, defined as the absence of relevant cardiac structural alterations such as moderate or severe hypertrophy, alteration of segmental contraction, Moderate or severe valvular disease, intraventricular obstructive gradient, or old myocardial infarction.
