I am afraid; any form of clearances for surgery cannot be given till one does a clinical examination and at times, certain investigations. In generic terms, if you have undergone angioplasty, then heart should not be a limiting factor for undergoing a hernia surgery. In fact, even if the arteries are blocked, these surgeries can be performed under proper cardiological supervision in centres equipped with good operation theatres and intensive care monitoring. I am afraid that’s about the most specific I can be for the query that you have posted and you should contact your cardiologist for the necessary clearance.
