Is Congestive heart Failure a condition like strep throat or a disease like heart disease?

Hi, catherine - It sounds like your question basically boils down to semantics. When someone is in congestive heart failure, their level of activity is limited by shortness of breath or fatigue. Usually this is a result of abnormal heart function (a 'cardiomyopathy'), but once they are adequately treated and feel back to normal again, they are technically no longer IN congestive heart failure. But they still have a cardiomyopathy because the underlying problem has not changed. So you COULD say that congestive heart failure is a clinical condition, but the cardiomyopathy is the underlying disease. You could argue that either way, though...

It is a heart disease. but the causative organism is the same which effect for sore throat.
All the signs and symptoms are of heart disease like chest congetion, shortness of breath, cynosis, cardiomegaly,
swelling etc
Congestive heart failure, or heart failure, is a condition in which the heart is unable to adequately pump blood throughout the body and/or unable to prevent blood from "backing up" into the lungs. In most cases, heart failure is a process that occurs over time, when an underlying condition damages the heart or makes it work too hard, weakening the organ. Heart failure is characterized by shortness of breath (dyspnea) and abnormal fluid retention, which usually results in swelling (edema) in the feet and legs.
The heart consists of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle, and four major valves: the mitral valve, the tricuspid valve, the aortic valve, and the pulmonary valve. Atria are relatively thin-walled chambers that receive blood from the circulatory system and from the lungs. Ventricles are muscular chambers that pump blood into the circulatory system and into the lungs.
Blood passes from the atria into the ventricles through two processes. During the "resting phase," when the ventricles are not contracting, the tricuspid and mitral valves open and allow some of the blood that has accumulated in the atria to flow passively through the valves into the ventricles. Then, the atria contract and actively pump blood out through the valves and into the ventricles. Once the ventricles fill with blood, they contract, pumping blood to the lungs and the rest of the body.
When the left ventricle cannot adequately pump blood out of the left atrium, or when one or more of the heart valves becomes leaky or narrowed (stenotic), blood can "back up" into the lungs, causing "left-sided" heart failure. When this occurs, the lungs become congested with fluid (called pulmonary edema), causing difficulty breathing and interfering with the movement of oxygen from the lungs into the bloodstream, causing fatigue.
When an abnormality or condition affects the flow of blood through the right ventricle, pressure in the blood vessels increases and fluid is forced from the blood vessels into body tissues. This "right-sided" heart failure causes swelling (edema), usually in the feet and legs, and sometimes, in the abdomen.
