Please pray for my father

I had a call from my brother about 40 minutes ago. My father, whom I am flying to Boston to see tonight God willing, is being taken to the hospital with 'chest pains.' No one knows what it is yet (and we are wondering how Dad - who has advanced Alzheimers - even managed to tell anyone in the nursing home that he has them), but given that he is nearly 85 bli ayin hara, they're not a good sign.
