We calculate the effects of finite density and temperature of isospinasymmetric strange hadronic matter, for different strangeness fractions, on thein-medium properties of vector $\left( D^{\ast}, D_{s}^{\ast}, B^{\ast},B_{s}^{\ast}\right)$ and axial-vector $\left( D_{1}, D_{1s}, B_{1},B_{1s}\right)$ mesons, using chiral hadronic SU(3) model and QCD sum rules. Wefocus on the evaluation of in-medium mass-shift and shift in decay constant ofabove vector and axial-vector mesons. In QCD sum rule approach, the properties,e.g., the masses and decay constants of vector and axial-vector mesons arewritten in terms of quark and gluon condensates. These quark and gluoncondensates are evaluated in the present work within chiral SU(3) model,through the medium modification of, scalar-isoscalar fields $\sigma$ and$\zeta$, the scalar-isovector field $\delta$ and scalar dilaton field $\chi$,in the strange hadronic medium which includes both nucleons as well ashyperons. As we shall see in detail, the masses and decay constants of heavyvector and axial-vector mesons are affected significantly due to isospinasymmetry and strangeness fraction of the medium and these modifications mayinfluence the experimental observables produced in heavy ion collisionexperiments. The results of present investigations of in-medium properties ofvector and axial-vector mesons at finite density and temperature of strangehadronic medium may be helpful for understanding the experimental data fromheavy-ion collision experiments in-particular for the Compressed BaryonicMatter (CBM) experiment of FAIR facility at GSI, Germany.
