Heart failure affects around 5.7 million Americans, and causes or contributes to roughly 335,000 deaths each year. There are many primary causes of heart failure.The most common include coronary artery disease and high blood pressure but can also include heart attacks, obesity, and diabetes, all of which place excessive demands on the heart muscle, making it difficult to produce the blood flow needed to sustain life. That extra demand for energy results in a loss of fuel efficiency when the heart needs it the most. CoQ10 is essential for the heart to maintain sufficient energy management. Adequate CoQ10 levels cause tissues such as the heart to burn fuel efficiently, repairing and preventing oxidative damage and ultimately restoring its function.
