The effect of exercise and antioxidant enzyme levels in syndrome X and coronary slow flow phenomenon: an observational study.

Objective: In this study the antioxidant enzyme [catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) ] levels at rest in patients with syndrome X and coronary slow flow are measured. Then it has been investigated whether there is any enzymatic difference between the normal controls and syndrome X patients or patients with coronary slow flow and ascertain if exercise has any effects on the antioxidant enzyme levels.

Methods: Fifty-five patients were included in this prospective observational controlled study.

Huge cardiac cyst hydatid causing cardiac symptoms and electrocardiographic changes.

Here we present a huge cardiac cyst hydatid case with wonderful echocardiographic and computed tomographic images, causing cardiac symptoms and electrocardiographic changes.

Evidence of left ventricular systolic and diastolic dysfunction by color tissue Doppler imaging despite normal ejection fraction in patients on chronic hemodialysis program.

Background: Cardiovascular diseases are responsible for about half of deaths and are the major cause of mortality in hemodialysis patients. The aim of this study is to assess left ventricular (LV) longitudinal myocardial functions by color tissue Doppler imaging (TDI) in patients with chronic renal failure on a regular hemodialysis program.

Methods: Thirty-one patients on a regular hemodialysis program (mean age 47 +/- 12 years; 17 males, 14 females) were included into the study.
