recognition of the natural history and responsible leading factors for regression of left ventricular hypertrophy after successful renal transplantation are very important. the aim of this study was to assess the regression of left ventricular hypertrophy after successful renal transplantation among uremic patients. in this study 27 uremic patients (18 males and 9 females) with an average age o...

objective(s):this study focused on the effect of waterpipe smoke exposure toxicity on the structure of albino rat’s ventricular tissue and their recovery. materials and methods: albino rats were divided into three groups: control, flavored, and unflavored. the control group was exposed to normal air while the flavored and unflavored groups were exposed to waterpipe smoke for a period of 90 days...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

Nuclear thyroid hormone (T3) receptors (TR) play a critical role in mediating the effects of T3 on development, differentiation and normal physiology of many organs. The heart is a major target organ of T3, and recent studies in knockout mice demonstrated distinct effects of the different TR isoforms on cardiac function, but the specific actions of TR isoforms and their specific localization in...

Depressed parasympathetic activity has been proposed to be associated with an increased risk of sudden death. Parasympathetic effects (PE) on cardiac electrophysiology during exercise and recovery have not been studied in patients with left ventricular dysfunction. We performed noninvasive electrophysiological studies (NI-EPS) and characterized the electrophysiological properties of the sinus n...

In a patient with repetitive disabling tachycardias refractory to pharmacologic treatment, the electrophysiologic study suggested the existence of atrioventricular nodal reciprocating tachycardia. During ventricular pacing, endoepicardial mapping of the lower atrium showed the atrial breakthrough point in an area of the lower interatrial septum close to the AV node crista. A selective atriotomy...

Among patients with Wolff-Parkinson-White syndrome, atrioventricular reciprocating tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) can coexist in a single patient. Direct transition of both tachycardias is rare; however, it can occur after premature atrial or ventricular activity if the cycle lengths of the two tachycardias are similar. Furthermore, persistent atrial...

Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1-V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thro...
