  In this paper, we study the Cauchy problem for the focusing inhomogeneous
nonlinear Schr\"{o}dinger equation with inverse-square potential \[iu_{t}
+\Delta u-c|x|^{-2}u+|x|^{-b} |u|^{\sigma } u=0,\; u(0)=u_{0} \in
H_{c}^{1},\;(t,x)\in \mathbb R\times\mathbb R^{d},\] where $d\ge3$, $0<b<2$,
$\frac{4-2b}{d}<\sigma<\frac{4-2b}{d-2}$ and
$c>-c(d):=-\left(\frac{d-2}{2}\right)^{2}$. We first establish the criteria for
global existence and blow-up of general (not necessarily radial or finite
variance) solutions to the equation. Using these criteria, we study the global
existence and blow-up of solutions to the equation with general data lying
below, at, and above the ground state threshold. Our results extend the global
existence and blow-up results of Campos-Guzm\'{a}n (Z. Angew. Math. Phys.,
2021) and Dinh-Keraani (SIAM J. Math. Anal., 2021).
