The effects of 6 months treatment with Sotalol on the blood pressure, left ventricular mass and function, were studied in patients with essential hypertension and left ventricular hypertrophy. Thirty-three patients (18 men and 15 women aged 53 +/- 11 years) were included initially and 26 were reviewed after 6 months of treatment. The left ventricular mass and function were evaluated by Doppler echocardiography and all recordings were interpreted "blind" at the end of the study by two operators. Treatment led to a significant reduction of the blood pressure (152 +/- 12/94 +/- 11 versus 166 +/- 18/100 +/- 9 mmHg) and of the heart rate (60 +/- 10 versus 76 +/- 12 beats per minute). The left ventricular mass index decreased by 8% (p less than 0.001) due to reduction in wall thickness. Resting left ventricular systolic function was unchanged. Left ventricular filling patterns improved with an increase in the E/A ratio which was reduced at the beginning of the trial.

Objectives: Ischemia/reperfusion (IR)-induced ventricular arrhythmia, which mainly occurs after the opening of coronary artery occlusion, poses a clinical problem. This study aims to investigate the effectiveness of pretreatment with coenzyme Q (CoQ) in combination with mitochondrial transplantation on IR-induced ventricular arrhythmias in aged rats.
Materials And Methods: Myocardial IR induction was performed by left anterior descending coronary artery occlusion for 30 min, followed by re-opening for 24 hr.

Background: Children with Tetralogy of Fallot (TOF) usually present with right heart abnormalities, however much is not known if these children presents with left ventricular dysfunction.
Objectives: This article is aimed to ascertain the left ventricular function of children with TOF compared with those without any congenital heart disease. It also elicits the correlation if any, between left ventricular mass and descending aorta blood flow.

Background: The initial outcomes of transcatheter aortic valve replacement in patients with left ventricular outflow tract calcification are poor. Furthermore, balloon-expandable transcatheter aortic valve replacement is associated with an increased risk of annular rupture, and self-expandable transcatheter aortic valve replacement is associated with worse post-operative residual paravalvular leakage grades. Therefore, developing an optimal method for transcatheter aortic valve replacement for patients with left ventricular outflow tract calcification is desirable.

Background: To study the relationship between the monocyte/high-density lipoprotein cholesterol ratio (MHR) and neutrophil-to-lymphocyte ratio (NLR) and coronary artery stenosis in Non-st-elevation acute coronary syndromes (NSTE-ACS) patients of different genders.
Methods: A total of 253 control and 800 NSTE-ACS patients were included, and clinic data (29 items) were also collected. NSTE-ACS patients were divided into low-risk (0-23) and high-risk (≥ 23) groups based on the Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score.
