Heart failure is a global health concern, with many patients being unresponsive to medical therapies. In end-stage disease, left ventricular assist devices (LVADs) offer an alternative to ...
Introduction: Peripheral veno-arterial extracorporeal membrane oxygenation (V-A ECMO) poses increased afterload to the injured heart. The reactivity of myocardial contractility to ECMO blood flow ...
Within the prior 24 months, I have had a financial relationship with a company producing, marketing, selling, re-selling, or distributing healthcare products used by or on patients: Receive the the ...
The heart pumps blood against the mechanical afterload from arterial resistance, and increased afterload may alter cardiac electrophysiology and contribute to life-threatening arrhythmias. However, ...
The evaluation of myocardial contractility is essential in cardiology practice. The gold standard for this evaluation is the end-systolic elastance, but it the method involved is complex.
Introduction The systolic performance of the heart is determined by 3 factors: preload, afterload, and contractility. The direct relationship between preload and cardiac output was formulated in the ...
Abstract: Obesity is associated with haemodynamic overload. In addition to the increased preload, left ventricular (LV) afterload is also elevated in obese individuals; an increased LV mass can alter ...
