Causes Of Heart Failure
What causes heart failure?
When we are in motion, increases metabolism throughout the body. The different body parts need then more blood to get enough oxygen and nourishment. A healthy heart can increase their activity so that blood circulation is satisfactory. A diseased heart is not capable of this, and the condition known as congestive heart failure.
Different types of heart disease can cause heart failure, but the most common is that it occurs after myocardial infarction. A portion of the heart muscle is dead then, and it is replaced by a rigid scar tissue. This reduces the hearts pumping ability. Years of high blood pressure can also be hard on the heart and cause heart failure.
For the same reason, the failure of the heart valves ( aortic stenosis, aortic insufficiency, mitral stenosis, mitral regurgitation ) provide heart failure due to increased wear and tear of the muscle. There are also a number of conditions that weaken the heart (cardiomyopathy) such as diabetes, infection, alcohol.
