Doesn't matter how short the runway at LGA is. V1 is adjusted for all criteria- weight, thrust, aircraft performance, runway condition, gradient, braking action, and runway length.
I've seen calculated V1 as low as 72 knots in the CRJ (due to snow/ice on the runway). If we had an engine failure after that point, we were to continue and per the performance we'd lift off prior to the end of the runway.
As long as you calculate V1 correctly and perform the appropriate abort/go decision and procedure in a timely manner, you will be protected (provided that the variables upon which V1 is calculated are all correct and the operating engine is producing the charted thrust).
