Cold Sweats and Dizziness
Sometimes, heart attacks cause flu-like symptoms out of nowhere. Cold sweats, or abnormal instances of profuse perspiration and chills, day and night are one of those symptoms. Cold sweats can happen regardless of how hot or cold it is around you and are a sign of low blood pressure, lack of oxygen, and also cardiogenic shock.
Cold sweats are often coupled with dizziness. You might not be able to see straight and have a hard time standing up. Lack of balance and wooziness are the result of disrupted blood pressure, arrhythmia, and, in the worst case scenario, internal bleeding.
If the lightheadedness advances to fainting spells, you have a medical emergency on your hands. Fainting is a sign that you could have a clot blocking oxygenated blood from reaching the brain.
