OBJECTIVE To explore the therapeutic effect and safety of target-dose metoprolol in treating chronic heart failure (CHF) patients complicated with diabetes mellitus (DM). Method s : One hundred and fifty-four elderly patients were randomly divided into an observation group and a control group (n=77), which were treated with target-dose metoprolol and conventional therapy, and routinely treated ...

BACKGROUND In adults, tissue Doppler imaging (TDI) is a recommended component of routine echocardiography. However, TDI velocities are less accepted in pediatrics, due to their strong variability and age dependence in children. This study examines the distribution of myocardial tissue Doppler velocities in healthy children to assess the effect of age with cardiac growth on the various echocardi...

BACKGROUND It is uncertain whether external electrical cardioversion (CV) of atrial fibrillation (AF) can cause myocardial injury identifiable by troponin I (cTnI). AIM To examine whether external CV of AF can cause cTnI rise as measured with high-sensitivity assay, and to identify factors determining this elevation. METHODS Patients with non-valvular AF selected for CV were included. Exclu...

OBJECTIVE To evaluate left ventricular function by echocardiography before and after kidney transplantation (KT). METHODS This analytical study included 50 patients that had successful KT in Shahid Beheshti Hospital, Babol, Iran from October 2005 to December 2007. The echocardiography study was performed by one cardiologist before and at least 3 months after KT. Data were analyzed by SPSS, an...

We studied the effects of right ventricular ischemia on left ventricular three-dimensional geometry and the end-diastolic pressure-volume relationship in 16 open-chest dogs before and after pericardiectomy. Left ventricular volume was calculated from three internal dimensions measured with ultrasonic crystals. In one group of eight dogs, right coronary artery (RCA) occlusion for 2 min with the ...

The action mechanism of natakalim, a novel ATP-sensitive potassium channel opener, was studied in ameliorating the congestive heart failure (CHF) after myocardial infarction. A total of 25 healthy Wistar male rats (age, 10 weeks; average weight, 300 g) were selected, and the CHF models after acute myocardial infarction (AMI) were prepared by ligation of left anterior descending branch. They wer...

M-mode echocardiographic findings are described in 21 patients with endomyocardial fibrosis. Features associated with right ventricular endomyocardial fibrosis include: (i) exaggerated motion and thickening of the anterior right ventricular wall; (ii) increased right ventricular end-diastolic dimension; and (iii) paradoxical septal motion. Pericardial effusion (viz an echo-free space behind the...

BACKGROUND Solid evidence shows that cardiac resynchronization therapy (CRT) improves prognosis, physical capacity and quality of life in selected groups of patients with chronic heart failure (CHF). Nonetheless, marked percentage of patients seem not to benefit from CRT. MATERIAL AND METHODS Sixty consecutive patients (aged 66.3 +/- 8.7 years, 57 men - 95%, 3 women - 5%) with CHF (71.7% with...

We studied nine freshmen and 14 senior oarsmen undergraduates during seven months of training and compared them with 17 age and sex-matched sedentary control subjects in order to assess the influence of heavy physical exercise on cardiac dimensions and maximal oxygen uptake. Standard M-mode echocardiographic techniques were used. At the start of the season senior oarsmen had a greater left vent...

Purpose: To evaluate the coronary thrombolytic effect of atorvastatin plus percutaneous intervention (PCI) for treatment acute myocardial infarction.Methods: From April 2019 to October 2020, 88 patients with infarction who were treated in Zhangqiu District People's Hospital randomly assigned receive either PCI (conventional group) or (combined group). Myocardial injury index, TnI, and creatine ...
