Cardiac contractility is a term that expresses the vigor of contraction or, more specifically, the change in developed force at a given resting fiber length (Berne and Levy, 1988). An increase in fiber length above resting increases the force of contraction (Frank–Starling mechanism), but it does not increase contractility.
