Is it true that if a person is having a heart attack, he also has high blood pressure?

Not necessarily: The stress of the pain or fear related to the heart attack can raise the blood pressure but does not always do so. If the heart is badly damaged, the blood pressure can actually get too low.

Not true: High blood pressure can make risk of heart attack greater ... And something stressful that causes a heart attack can initially also cause high blood pressure ... But a heart attack usually will cause ones' blood pressure to drop ...

Sometimes: Patients having a heart attack may be having pain and the pain causes them to have increase blood pressure. Also, there are certain molecules released into the blood when a patient is having a heart attach that can cause the blood pressure to go up. Htn can cause heart attack. Having said that, at times patients can have low blood pressure while having a heart attach due to damage of the heart.

Htn: Htn is not a cause of heart attack. Htn may increase risk of heart attack ( that's why we treat htn). We watch the blood pressure during a heart attack to prevent elevated BP or hypotension (low bp) , both can happen during a heart attack.

No: People can have heart attacks for a variety of reasons. One of them is high blood pressure, but others include coronary artery disease, drugs, coronary spasm and many more; not necessarily associated with high blood pressure.
