will increase HCM and MVP murmur , increase TPR less blood passes through obstruction and more murmur to decrease murmur you need more blood passing through it that separates the edges ........

yes might increase preload but increased TPR more and leads to less flow of blood through the obstruction .... and increases the murmur in HCM

the main aim is to understand that HCM murmur is different than others where increase in blood blow decreases the murmur because it separates the hypertrophied septum and ant mitral valve leaflet thus decreases the murmur and this is possible by increasing the preload or LVEDV

increasing afterload or TPR will increase the murmur ....that is why hand grip , squatting increases HCM murmur ......

hope this helps .....
