The influence of the peripheral reflection wave on left ventricular hypertrophy in patients with essential hypertension.
The objective of this study was to clarify the relationship between afterload, which consists mainly of the vascular reflection wave, and left ventricular hypertrophy in patients with untreated essential hypertension using the fingertip photoplethysmogram (PTG) and second derivative wave (SDPTG) methods, the simplest and most convenient tools for pulse wave analysis. The augmentation index (AI)...
متن کاملMicrovolt T-wave alternation in left ventricular hypertrophy patients
Background Sudden cardiac death (SCD) is responsible for 11% of all deaths and 50% of all cardiovascular deaths. Hypertrophic cardiomyopathy (HCM) is the most common cause of SCD among the young patients. SCD is often the first manifestation of the disease. There are 5 major risk factors for SCD in patients with HCM. However, no single risk factor can be used as a screening test in assessment o...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
متن کاملLeft Ventricular Hypertrophy Familial Predisposition of Left Ventricular Hypertrophy
METHODS Echocardiographic and anthropometric measurements were performed in 2,293 individuals who participated in the echocardiographic substudies of population-based MONICA Augsburg surveys. In addition, a total of 319 siblings of survey participants with echocardiographic evidence of LVH were evaluated. The risk of these siblings to present with LVH or abnormal LV geometry was estimated by co...
متن کاملAugmentation index, left ventricular contractility, and wave reflection.
Augmentation index (AIx), a correlate of mortality, is thought to be influenced by left ventricular contractility and wave reflections. However, the relationship of AIx with left ventricular contractility changes has never been assessed, and the wave reflection theory has recently been questioned. This study sought to examine arterial waveform changes in response to reduced "wave reflection" an...
