Are there any words omitted at the beginning of this sentence? It seems to me that the preposition like "as a result of" is necessary here.

I see what you're saying! So here, "as a result of" is implied through the tone and sentence structure. The first line indicates the response, and the second line explains what the response is. This creates a dramatic effect in the sentence and is likely to grab people's attention more than if it started with "as a result of." In terms of punctuation, a "colon" would create the same effect. Ex: A surprising outcome: The Bears lost the football match. Ex: A generous gift: the mayor donates money to the community center.
