Heart failure is a disease characterized by cardiac remodeling or progressive dilation of left ventricle and a consequent reduction in contraction. Ventricular remodeling has been shown to be a negative prognostic factor alone, and therefore the most beneficial drugs are those that prevent or reduce left ventricular dilation. The pharmacological therapy of heart failure, although maximal, has proven to be not fully effective. The aim of our research was to evaluate resynchronization therapy in a lot of patients, monitoring their cardiac performance before and after cardiac resynchronization therapy.

The aim of our study was to evaluate the expression of glial enteric cells at different stages of differentiation of colorectal neoplasms and to correlate these changes with the tumor proliferation index and with the sympathetic influences evaluated by the expression of beta-2 adrenoreceptors. Given that nowadays colorectal neoplasm is a major public health problem and that the molecular mechanisms responsible for malignant transformation are not fully yet elucidated, more studies are needed in order to establish other intracellular signaling pathways in such a neoplasm. By this study we concluded that the proportional decrease in the density of glial enteric cells in colorectal cancer with the degree of tumor differentiation and also their inverse correlation with the tumor proliferation index and with the expression of the adrenergic beta-2 adrenoreceptors can be considered a negative prognostic factor in this type of cancer.

The aim of our study was to assess the percutaneous coronary angioplasty versus coronary artery bypass grafting in the treatment of the left main coronary artery disease. The study was a prospective, analytical, observational descriptive one, it included a total number of 83 patients, consecutively included in order to avoid bias, for a period of three years between October 2012 and December 2015. The follow-up was performed for 3 years, initially at one month, then at an interval of three to six months. The primary clinical endpoint was mortality of any cause of the patients included in the study. Other main objectives assessed in our study were symptomatic ischemic heart disease manifested with angina pectoris, the need for myocardial revascularization, nonfatal myocardial infarction, and reduction of left ventricular ejection fraction. In patients with LMCAD, we noticed an increase in mortality in patients with PCI vs. CABG, recurrence of angina pectoris, acute myocardial infarction, myocardial revascularization, and depression of the ejection fraction of the left ventricle. In conclusion, the treatment of left main coronary artery disease by using coronary artery bypass grafting is superior to treatment using percutaneous coronary angioplasty.

Cardiac affectation is one of the leading causes of death in the world. Rhythmic disorders such as ventricular extrasystoles, atrial extrasysoles, atrial fibrillation, atrial flutter represent a major risk factor with a gloomy progression and prognosis. Our goal was to analyze the existing arrhythmia risk in patients with chronic hepatic disease. Being known the alteration of the somatic status of the patient with liver cirrhosis or other chronic liver disease in the presence of comorbid cardiac symptoms, we consider vital to prevent arrhythmia risk in hepatic pathology.

Alcoholism use disorders are very frequent present all over the world. The use of alcohol is responsable for many behavioral symptoms like impulsivity, violence, depressive mood and anxiety. The aim of our research was to find the clinical and the biochemical changes induced by alcohol at the patient with mental illness.
