Comparison of left atrial size in hypertensive patients with or without left ventricular hypertrophy by Echocardiography
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 12
Abstract
Hypertension affects approximately one billion individuals worldwide and this figure is predicted to increase to 1.5 billion by 2025.Hypertension remains the most common, readily identifiable, and reversible risk factor for myocardial infarction, stroke, heart failure, atrial fibrillation, aortic dissection and peripheral arterial disease. The cardiac effects of systemic hypertension include systolic as well as diastolic dysfunction whereas increase in Left Ventricular mass has been shown to be a predictor of cardiovascular events, Left Atrial size is associated with likely hood of developing AF, indicator of diastolic function and in addition it is a predictor of stroke. This was a Cross sectional analytical case control study comprising 119 hypertensive patient conducted in the Department of Medicine Pt. J.N.M. Medical College and Dr. B.R.A.M. Hospital Raipur from August 2014 to Sept 2016 with aims and objectives to asses Left Atrial size in subjects with systemic hypertension with or without LVH by echocardiography & correlate Left Atrial size, Left Atrial Volume with Left Ventricular Hypertrophy LV mass & stages of systemic hypertension. Result and conclusions: Left Atrial size , mean Left Atrial Volume & mean Left Atrial Volume Index was found to be significantly higher in Left Ventricular Hypertrophy subjects compared to those without Left Ventricular Hypertrophy (p<0.0001). Study also suggests that there is significant positive correlation between Left Ventricular Hypertrophy and Left Ventricular mass. correlation was found to exist between Left Atrial Volume Index and Left Ventricular mass (r=0.244),which was statistically significant (p=0.007), Suggesting that increase in Left atrial volume occur even in the absence of Left Ventricular Hypertrophy which means that volume-based measurements are more sensitive and detect Left atrial enlargement at an earlier stage than diameter-based measurements.
