Support for Dad's Heart Recovery

My father had a heart attack on Friday, he was transported to a different hospital with great doctors. Monday morning he had surgery to repair an artery that was 90% blocked and one artery that is 50% blocked. Due to him having a heart attack and this procedure he is unable to go back to work where he was as the conditions are not suitable for someone with heart issues and a Stent in. Any and all help is appreciated.
