Detailed Answer:
I am Dr.Rajesh Teli,MD.I have gone through your query.
Thanks for using HCM.
I would like to reply your query in the sequence asked by you.

1. As such Blood group has no relevance with procedure of angiography, unless there is some bleeding disorder blood transfusion is not required for angiography.

2. Incedence of stroke after angiography is very rare.
3. CT coronary angiography is non invasive procedure with high negative predictive value. That means if CT angiography is normal then you can be pretty sure that patient will not need any procedure like angioplasty or bypass. However if there are blocks detected on CT angiography then he will need invasive angiography to exactly quantify blocks and to decide further course of action.
So decision whether to go for CT angio or conventional angio depends on his probability of having blocks. If your father is diabetic, Hypertensive, obese, having family history of heart disease and ECG and exercise test are pointing towards high possibility of blocks then you should opt for routine angiography.

My best wishes
