Heart failure
Initially, only the performance under heavy physical stress is reduced, then breathing is difficult, even at rest. The ankles are swollen, the sleep is disturbed by constant toilet habits. Approximately one million German know the symptoms of chronic heart failure from their own bitter experience. The heart is a hollow muscle and with his lifelong, permanent pumping power of the engine cycle. From the strength of the muscles of the heart, it depends on how effectively the heart and circulatory system and how well it can adapt to physical stress. The heart muscle can contract no longer sufficient, sufficient cardiac output no longer meet the requirements – the first in a special effort is even later, the pumping capacity to cope alone only with difficulty. Chronic heart failure is the most common diseases in Western nations, it is among the causes of death in third place – after the coronary heart disease (CHD) and heart attacks and lung cancer before.
Permanent cardiac overload
Basically, the heart can like other muscles trained by regular use and thus become more efficient. Physical stress, which is related with the increase of blood pressure and heart rate requests, and promoting the heart muscle. But: Chronic overtax the heart muscle, as can happen with certain diseases exceeds its adaptability in the long run. The body tries to regulate the cardiac output so that all institutions are adequately supplied. But that’s like a weak motor drives a heavy car – at every pitch he is slower. Then switch back, the driver must take a walk and high speeds, to ever come up to the mountain. But in the long run harm the high-speed driving and the engine output decreases further. Transferred to the heart means: It beats faster, blood pressure increases, so more blood can be transported per heart beat. Should this overload, the heart is damaged even more and can afford even less than before. The heartbeat is increased even more in order to supply the organs better. This increases the heart muscle and weakening him even more. Once underway come into this vicious circle is hard to stop. Therefore, it is important to the onset of heart failure as early as possible to counteract and to strengthen the heart again.
Causes of heart failure
We distinguish a primary heart failure, in which an independent, mostly genetic disease of the heart muscle itself is the basis of the secondary heart failure, which develops the limited pumping capacity as a result of chronic overloading of the heart healthy in itself. Various diseases can affect the heart muscle. These include congenital abnormalities of the cardiovascular system, chronic circulatory disorders in patients with coronary heart disease, long-term effects of heart valve damage and heart muscle diseases such as dilated cardiomyopathy, an enlargement of the ventricle, which may occur eg as a result of myocarditis. But even long-standing high blood pressure or chronic alcohol abuse, hormonal disorders (eg thyroid disease), diseases of kidney, lung and sustained anemia can lead to heart failure.
