CHF usually worsens over time and the yearly mortality rate is about 10 percent.

One of the causes is believed to be excessive oxidative stress on the heart muscles. Oxidation damages the heart muscles and reduces the ability of the heart to pump blood through the body.It has been suggested that the use of antioxidants could reduce oxidative stress and ultimately help the heart to work better. Vitamin C is known for being a powerful antioxidant that is readily utilized by many tissues, including heart muscle cells.

Vitamin C is not really a vitamin.It is a nutrient that is essential for many metabolic pathways.Interestingly, vitamin C is made by most animals with the exception of bats, guinea pigs and the primate group that includes humans.Although a true deficiency of vitamin C is rare, it can result in the disease scurvy. …
