Causes of Heart Failure: When The Heart Is Weak?

Causes of Heart Failure

Causes of Heart Failure: Heart failure is cardiac insufficiency in which the heart of those affected can no longer pump blood properly through the body and can therefore no longer supply it with sufficient oxygen.

Most often, patients with such cardiac insufficiency are impaired during physical exertion, as they are breathless, so to speak. We have summarized the most important information about heart failure.

Causes of Heart Failure:

In general, all diseases that have a negative effect on the heart muscle can be counted among the causes of heart failure. The main causes can be:

Genetic Predisposition:

As with many other diseases, genetics can also play a role in heart failure. If there have been cases of heart muscle disease or an enlarged heart in the family, patients may be more prone to heart failure than other people.

Coronary Heart Desease:

It is one of the most common triggers for insufficiency, especially after a heart attack. The blood vessels clog and consequently the heart muscle can no longer be properly supplied. This leads to a reduced performance of the entire heart.

High Blood Pressure:

Especially if high blood pressure goes undetected and untreated, it can either lead to coronary artery disease or directly to heart failure. The excessive exertion that the heart has to make in high blood pressure can develop into a major problem for those affected in the long run.

Valvular Heart Disease:

In the case of a congenital or acquired heart valve defect, a not fully functional valve is sufficient for heart failure to occur. Due to the malfunction of one or more heart valves, the heart has to increase its performance and is also overstrained in this case.

Other causes of heart failure can be diabetes, sleep apnea and cancer therapies using chemotherapy or radiation therapy.

How to Recognize Heart Failure:

The symptoms of a possible heart failure are quite general, but should still be carefully observed and ideally discussed with a doctor. These can be:

Water Retention:

Characteristic here are water retention on the back of the foot, the ankles and the shin. For many people this is quite normal in summer, for example. However, if you feel an increased need to urinate at night, this could indicate that the blood has built up during the day and that the accumulated fluid is now flowing back again at night.

Shortness of Breath:

Difficulty breathing can be a sign of heart failure, especially if it occurs not only during strenuous activities such as climbing stairs, but also gradually while lying in bed or on the sofa.

Other typical symptoms of this type of heart failure can also include an irritation of the throat, in which water has accumulated in the lungs, as well as decreased performance , states of exhaustion and frequent dizziness.

Acute Heart Failure:

In acute heart failure, various symptoms occur immediately and more intensely, for example during chronic insufficiency or after a heart attack. Breathlessness, coughing, an unusually fast heartbeat and rattling to boiling breath noises are not uncommon. If acute heart failure is suspected, you should immediately consult a doctor in order to initiate appropriate therapeutic measures.

Therapy for Heart Failure:

Even if the diagnosis of heart failure is initially a big shock for those affected, there are still good therapeutic options so that an almost normal and active life can be led. During therapy, the attending physician not only deals with the insufficiency itself, but also addresses the cause of the disease in order to be able to develop a holistic treatment approach.


What cause bad breath?


As individual as the causes of such a heart failure are, the patient is also advised and treated individually. By the appropriate medication, a possible operation (if necessary) and a healthy and stress-free as possible of life, quality of life and life expectancy of patients can be significantly improved.

Exercise for Heart Failure:

A diagnosis of heart failure does not necessarily mean that you are no longer allowed to exercise or move. Rather, it depends on the type of physical activity and the mix of movement and rest. Since exercise can demonstrably increase well-being, you should not completely do without it if you have a corresponding illness. It is best to speak to your doctor about what is right for you here.
