Dizziness
Feeling lightheaded, dizzy or even fainting could also suggest that blood flow to your brain is decreased. This is known as one of the main causes of heart attacks and strokes. Sometimes, these conditions would occur when you take some blood pressure-reducing drugs, which leads to an unexpected drop in your blood pressure and reduces blood circulation in your body. Report a seemingly harmless sign such as dizziness to your doctor might be helpful in determining and preventing the occurrence of a possible heart attack. [10]
