Most Common Symptoms Of A Heart Attack

Feeling Lightheaded

Lightheadedness is a symptom of a heart attack that typically occurs more in women than in men. Brain tissues are some of the most demanding tissues in the body when it comes to their oxygen and nutrient requirements. During a heart attack, the heart fails to pump enough oxygenated blood out to the rest of the body. The brain does not receive enough blood, and the tissues become starved of oxygen. The cells start to shut down and can cause the affected individual to dizzy or lightheaded. Medically, this malfunction is known as a drop in blood pressure. These symptoms typically occur when the affected individual is in an upright or standing position, as the force of gravity combines with the insufficient beating of the heart to inhibit the proper amount of blood from reaching the tissues in the brain. Nausea is often accompanied by both dizziness and lightheadedness that occur with a drop in blood pressure. Therefore, nausea may also accompany lightheadedness during a heart attack.
