It led to the creation of NATO in 1949.
The Warsaw Pact was the alliance of Eastern European countries which had sunk into communism.
Nato(North Atlantic treaty organization) was founded in 1949 as a dialectical response to prevent the communist contamination.
The Warsaw Pact was formed in 1955, six years after NATO.
The Warsaw Pact integrated the military forces of Eastern Europe under Soviet control. More immediately it was a response to West Germany being integrated into NATO.
In that sense the question should be reversed as it was a reaction to action by the West rather than the other way around.
It certainly contributed to the heightened tension of the Cold War associated with that period.
