Electrophysiological validation of total atrial conduction time measurement by tissue doppler echocardiography according to age and sex in healthy adults.

Background: We sought to validate total atrial conduction time (TACT) measurement via tissue Doppler imaging (TDI) by comparing the electrophysiological study (EPS) measurements of healthy subjects, according to age and sex.

Methods: Eighty patients with normal EPS results were included. TACT was measured by EPS and TDI.

Evaulation of atrial conduction abnormalities and left atrial mechanical functions in patients with subclinical thyroid disorders.

Introduction: Changes of thyroid hormones levels may lead to effects, not only in ventricular function, but also atrial function. The aim of this study was to investigate left atrial (LA) mechanical functions, atrial electromechanical coupling and P wave dispersion in patients with subclinical thyroid disorders.

Material And Methods: Eighty patients with subclinical thyroid disorders and forty controls were included.

Erythrocyte sedimentation rate in acute myocardial infarction as a predictor of poor prognosis and impaired reperfusion.

Aim: To investigate whether the elevated erythrocyte sedimentation rate (ESR) is associated with an adverse prognosis in the patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).

Methods: It included 140 consecutive patients undergoing primary PCI for acute STEMI, 12 hours after symptom beginning and 50 healthy age and sex matched control subjects. All patients were categorized into two groups defined by the median ESR level on admission.

Evaluation of left ventricular systolic asynchrony in patients with subclinical hypothyroidism.

Background: The heart was very sensitive to fluctuating thyroid hormone levels. To assess intra-left ventricular (LV) systolic asynchrony in patients with subclinical thyroid dysfunction.

Methods: Fifty patients with subclinical hypothyroidism and 40 controls were included.

Evaluation of left atrial mechanical functions and atrial conduction abnormalities in patients with clinical hypothyroid.

Background: The aim of this study was to investigate left atrial (LA) mechanical functions, atrial electromechanical delay and P wave dispersion in hypothyroid patients.

Methods: Thirty-four patients with overt hypothyroid and thirty controls were included. A diagnosis of overt hypothyroid was reached with increased serum TSH and decreased free T4 (fT4) levels.

[Endomyocardial disease: a case report].

Endomyocardial disease is a form of restrictive cardiomyopathy, of unknown etiology, which occurs most commonly in tropical and subtropical areas. It is characterized by the formation of endomyocardial fibrosis of the apical and subvalvular regions of one or both ventricles. A 29-year-old male patient was admitted with restrictive cardiomyopathy and decompensated heart failure.
