Panel of images demonstrating calculation of echocardiographic ventricular arterial coupling in pediatric dilated cardiomyopathy. In this example, end systolic volume and stroke volume are calculated by Simpson's method. The same can also be calculated by 5/6 area length method and left ventricular outflow tract velocity time integral. Normal values for ventricular and arterial elastance and ventricular arterial coupling are given in text.

Ventricular-arterial coupling, earlier used for research and experimental purposes, is being used currently for bedside patient evaluation and decision making. Its use in adults with heart failure has been proven. In pediatric heart failure, due to dilated cardiomyopathy, its use as a prognostic tool has been first documented in this study, and cut...

Individuals with schizophrenia have a reduced life-expectancy compared to the general population, largely due to an increased risk of cardiovascular disease (CVD). Clinical and epidemiological studies have been unable to unravel the nature of this relationship. We obtained summary-data of genome-wide-association studies of schizophrenia (N = 130 64...
The left ventricular ejection fraction does not accurately predict exercise capacity or symptom severity and has a limited role in predicting prognosis in heart failure. A better method of assessing ventricular performance is needed to aid understanding of the pathophysiological mechanisms and guide management in conditions such as heart failure. I...
We report the case of a 5-year-old who had interstitial invasion of his kidneys with group A Streptococcus (GAS). Glomeruli and tubules were relatively preserved. He recovered from this event and was admitted a couple of months later with dilated cardiomyopathy needing a heart transplant. To our knowledge, this is the first reported case of direct...
