It doesn't: Although high blood pressure is a risk factor for coronary heart disease, there is no evidence that there is an acute rise in blood pressure prior to a heart attack.

Not a direct cause: No number is the "magic number" but very high pressures (for example >200/>110) when associated with angina are considered a "hypertensive emergency" and should be promptly treated. Symptoms of stroke, heart failure, kidney failure, or encephalopathy (confusion) are the key symptoms of a hypertensive crisis.
Dr. Michael Depietro

Varies: High blood pressure over years damages blood vessels leading to things like stroke & heart attack. BP > 140/90 over time increases the risk for these problems. The longer the time and the higher the blood pressure, the > risk. No hard and fast cut off. If the blood pressure goes up quickly to very high levels (> 180/110 or so) can cause problems like heat failure, stroke more suddenly, .

See your doctor: Heart attacks can be life-threatening. If you are not feeling well and having chest pain you should go to the emergency room or call an ambulance. If you feel like this all the time and nothing seems to be new or getting worse, you should probably call your doc and get checked out in the office.

Yes: High blood pressure is one of the major risk factors for heart attacks. If you have it, take steps to keep it under control with health diet, regular exercise, weight loss if needed, limited alcohol consumption, avoidance of tobacco and medications if needed. You should also find out what other risk factors for heart attack or stroke you have and address them as well.
