How long does it take a massive heart attack to kill you?

Briefly. The first signal can be sudden death- as pain happens.
Seconds.. The most deleterious effect of any heart attack is electrical instability of the heart leading to fatal arrhythmias. That is why the internet tells you to cough if you feel chest pain and light headed, it can keep your blood pressure up. Otherwise, death will ensue in seconds (yes, it really works). If you are asking for long term, that depends on several factors, re-ask your question if so.

Diagnosed with coronary microvascular disease. Can this kill me / cause heart attack? Is it dangerous? Drs around here dont know much about it.

Microvascular ds. Coronary microvascular disease describes poor oxygen supply to the heart despite normal arteries; the idea is that the tiny blood vessels don't allow normal flow. It is often discussed but is hard to diagnose. In my experience most people given this diagnosis do not actually have proof of it.
