Morphological changes in the arterial pressure waveform following hemodynamic therapies in critical care: A clinical proof‐of‐concept study in older adults

Physiological Reports
Clinical management of hemodynamic instability remains challenging as underlying mechanisms are complex. A recent in‐silico study showed that peripheral arterial waveform analysis can differentiate deficits in preload, afterload, and contractility.

Balancing Maternal Cardiac Risk and Anaesthetic Safety: A Case Series on Segmental Spinal Anaesthesia [PDF]

Journal of Clinical and Diagnostic Research
Pregnancy evokes significant alterations to the physiologic conditions in females and it is more dramatic for women suffering from valvular heart diseases or congenital cardiovascular diseases. Increases in blood volume and cardiac output, as well as the

Prognostic utility of blood pressure-adjusted global and basal systolic longitudinal strain

Echo Research and Practice, 2016
Assessment of global longitudinal systolic strain (GLS) and longitudinal systolic strain of the basal segments (BLS) has shown prognostic value in cardiac disorders. However, strain is reduced with increased afterload. We assessed the prognostic value of

Non-linearity of end-systolic pressure–volume relation in afterload increases is caused by an overlay of shortening deactivation and the Frank–Starling mechanism

Scientific Reports, 2021
The linearity and load insensitivity of the end-systolic pressure–volume-relationship (ESPVR), a parameter that describes the ventricular contractile state, are controversial.

Levosimendan, milrinone, and dobutamine in experimental acute pulmonary embolism

Pulmonary Circulation, 2021
Acute pulmonary embolism is a frequent condition in emergency medicine and potentially fatal. Cause of death is right ventricular failure due to increased right ventricular afterload from both pulmonary vascular obstruction and vasoconstriction ...

Understanding cardiopulmonary interactions through esophageal pressure monitoring

Frontiers in Physiology, 2023
Esophageal pressure is the closest estimate of pleural pressure. Changes in esophageal pressure reflect changes in intrathoracic pressure and affect transpulmonary pressure, both of which have multiple effects on right and left ventricular performance ...

Dual Endothelin Receptor Blockade Abrogates Right Ventricular Remodeling and Biventricular Fibrosis in Isolated Elevated Right Ventricular Afterload. [PDF]

PLoS ONE, 2016
BACKGROUND:Pulmonary arterial hypertension is usually fatal due to right ventricular failure and is frequently associated with co-existing left ventricular dysfunction. Endothelin-1 is a powerful pro-fibrotic mediator and vasoconstrictor that is elevated

Maximum Tolerable Afterload and Afterload Reserve for the Evaluation of Ventricular Performance

Japanese Heart Journal, 1978
The concept of a maximum tolerable afterload and an afterload reserve was proposed for evaluating ventricular function. A maximum tolerable afterload was defined as the systolic ventricular pressure during gradual proximal arterial obstruction, at the point where a distal arterial pressure or flow began to fall.

Increased Afterload Following Myocardial Infarction Promotes Conduction-Dependent Arrhythmias That Are Unmasked by Hypokalemia

JACC: Basic to Translational Science, 2017
Summary: Although the pathophysiological significance of resistant hypertension in post–myocardial infarction (MI) patients is established, the mechanisms by which increased afterload in that setting worsens outcome are unclear.
