OBJECTIVES To determine both ventricular functions and tissue Doppler echocardiography (TDE)-derived myocardial performance index (MPI) in patients with coronary artery ectasia (CAE). SUBJECTS AND METHODS Twenty-five patients with CAE (13 men; mean age 57 ± 9 years) and 25 age- and sex-matched controls without CAE (8 men; mean age 54 ± 10 years) were enrolled in the study. Left and right vent...

OBJECTIVE Pulmonary artery occlusion pressure and central venous pressure have been considered to be reliable measures of left and right ventricular preload in patients requiring invasive hemodynamic monitoring. Studies in recent years have questioned the correlation between these estimates of ventricular filling pressures and ventricular end-diastolic volumes/cardiac performance variables in s...

conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...

STUDY OBJECTIVES There are few data on the effects of continuous positive airway pressure (CPAP) therapy on the structural and functional characteristics of the right heart in patients with obstructive sleep apnea (OSA). We sought to leverage the advantages of cardiac magnetic resonance imaging (CMR) and hypothesized that CPAP treatment would improve right ventricular (RV) function in a group o...

BACKGROUND Pressure-induced left ventricular hypertrophy is one of the mechanisms responsible for an impaired coronary vasodilating capacity leading to myocardial ischemia and angina. The aim of the study was to investigate myocardial perfusion using cardiovascular magnetic resonance in patients with arterial hypertension and a history of chest pain and normal coronary angiography, and to estim...

In patients with patent ducts arteriosus, cardiovascular system is generally exposed to much overload and subsequently several complications as congestive heart failure, pulmonary hypertension and infective endocarditis. These complications depend on the size of the defect and the timing of intervention [1]. It is important to close PDA to prevent occurrence of these complications [2]. Today pe...
