Valsalva Maneuver in diastolic heart failure, diastolic dysfunction and systolic heart failure clinically BNP and echocardiography
Journal Title: Journal of Cardiovascular Medicine and Cardiology - Year 2018, Vol 5, Issue 4
Abstract
Background: Valsalva maneuver one of the oldest method to diagnose heart failure, it’s cheap ,non-invasive ,bedside tool .Its well-studied in systolic heart failure patients which showed abnormal response either square wave or absent phase IV ,however in diastolic heart failure and diastolic dysfunction were not investigated. Methods: 70 patients were included in our study they were divided into three groups group 1 diastolic heart failure based on echocardiography and BNP above 100pgL/ml , group 2 diastolic dysfunction based on echocardiography and BNP less than 100 pg/ml and group 3 systolic heart failure ,they went all clinical examination ,BNP were taken ,Valsalva maneuver at 30 mmhg for at least 15 sec using two sphygmomanometers first connected to mouth piece and the other to monitor blood pressure while the physician auscultates brachial artery patient is asked to perform forced expiratory effort against closed airway for at least 15 second and then asked to release and absence or presence of Korotkoff sounds assessed and heart rate is recorded baseline and after strain and full study echocardiography and using in apical 4 chamber view Simpson method to measure right and left ventricle area at baseline , peak strain and after release.
