Left Atrial Mechanical Function and Global Strain in Hypertrophic Cardiomyopathy
BACKGROUND Atrial fibrillation is the most common arrhythmia and is associated with adverse outcomes in hypertrophic cardiomyopathy (HCM). Although left atrial (LA) remodeling and dysfunction are known to associate with the development of atrial fibrillation in HCM, the changes of the LA in HCM patients remain unclear. This study aimed to evaluate the changes in LA size and mechanical function ...
متن کاملLeft Atrial Size and Function in Hypertrophic Cardiomyopathy Patients and Risk of New-Onset Atrial Fibrillation.
BACKGROUND The value of left atrial (LA) diameter, volume, and strain to risk stratify hypertrophic cardiomyopathy patients for new-onset atrial fibrillation (AF) was explored. METHODS AND RESULTS A total of 242 hypertrophic cardiomyopathy patients without AF history were evaluated by (speckle-tracking) echocardiography. During mean follow-up of 4.8±3.7 years, 41 patients (17%) developed new-...
متن کاملLeft atrial remodeling and mechanical dysfunction in hypertrophic cardiomyopathy
Background Patients with hypertrophic cardiomyopathy (HCM) and LA enlargement have more serious cardiovascular events. This study sought to determine the contribution of left atrial (LA) remodeling and mechanical function to hypertrophic cardiomyopathy (HCM) by comparing HCM patients to ageand gender-matched control subjects and young healthy control subjects, and also to assess whether LA remo...
متن کاملCombined apical hypertrophic cardiomyopathy and left atrial myxoma.
A patient had apical hypertrophic cardiomyopathy and left atrial myxoma. We believe that this is the first description of such a combination.
متن کاملRadionuclide assessment of left ventricular function in hypertrophic cardiomyopathy.
To determine the relationship of left ventricular function and ventricular tachycardia, 48 hour ECG monitoring and technetium-99m gated equilibrium radionuclide angiography were performed in 84 consecutive patients with hypertrophic cardiomyopathy and sinus rhythm. Measurements of ejection fraction (EF), peak ejection rate (PER, edv/s), peak filling rate (PFR, edv/s) and time to peak filling ra...
