Increase in Afterload Handgrip?

Handgrip: Increases afterload. Hand gripping increases the strength of aortic regurgitation
aortic regurgitation
The incidence of clinically significant aortic regurgitation (AR) increases with age, typically peaking in the fourth to sixth decade of life. It is more common in men than women. The prevalence of AR in the Framingham study was reported to be 4.9%, with regurgitation of moderate or greater severity occurring in 0.5%.
, mitral regurgitation, and ventricular septal defect murmurs. It decreases the intensity of murmurs due to hypertrophic obstructive cardiomyopathy and mitral valve prolapse.
How does handgrip affect afterload?
The handgrip maneuver increases afterload by squeezing the arterioles and increasing total peripheral resistance.
Why does increased afterload decrease HOCM murmur?
When the afterload is decreased, there is less resistance to blood flow from the LV through the aortic valve; this means less blood regurgitates through the mitral valve, thereby decreasing the intensity of the murmur.
