Only the Avatar was the master of all four elements. Only he could stop the ruthless Fire Nation from conquering the world. But when the world needed him most, he disappeared. Until now... On the South Pole, a lone Water Tribe village struggles to survive.
Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.
Actually, heart failure means that the heart isn't pumping as well as it should be. Congestive heart failure is a type of heart failure which requires seeking timely medical attention, although sometimes the two terms are used interchangeably. Your body depends on the heart's pumping action to deliver oxygen- and nutrient-rich blood to the body's cells.
