When do I take a risk to heart?


What consequences do you have potassium and magnesium for the heart?

Many people suffer from a lack of minerals, without knowing that. If there is a lack of potassium and magnesium, however, this can have dramatic effects on our health, alerting experts from the Heart Foundation of Germany in a recent statement. Due to the increasing risk, doctors of potassium and magnesium levels should be monitored regularly by a doctor, especially in cases of heart arrhythmia, heart failure, kidney disease and the use of some heart medications

The lack of potassium and magnesium favors other cardiac atrial and arrhythmic fibrillation, experts of the Heart Foundation of Germany. Therefore, it would be appropriate to counteract an equivalent defect by supplying potassium and magnesium. However, many victims are not aware that their levels of these minerals are too low. Regular medical checks would be particularly appropriate for some risk groups.

Minerals with a firm influence on cardiac function

Potassium and magnesium are important for the normal heart function because they stabilize the heart cells electrically, explain the Heart Foundation of Germany. Minerals form electrical stimuli in the heart cells and are of vital importance for signal transfer between the cells, the scientific society continues. "However, potassium and magnesium have a stabilization effect only if their concentration in the normal range," emphasizes Professor Dr Med. med. Andreas Götte of the Heart of Germany Institute of Scientific Advisory Board. The normal range of potassium is between 3.6 and 4.8 mmol / l, for magnesium it is 0.7 to 1.05 mmol / l – with small doses depending on the lab's method.

More accusation to cardiac arrhythmia

If it falls below the lower limit, the lack of potassium (hypokalaemia) and the lack of magnesium (hypomagnesemia) in the cells lead to increasing the celluline, resulting in more extra burden heart (extrasystoles) explains, the experts explain. The heart is more exposed to arrhythmia in the atria (atrial fibrillation) and heart chambers. In the worst case, extreme magnesium deficiency could promote life-threatening ventricular fibrillation.

Symptoms of potassium and magnesium

As there are other symptoms of a potassium deficiency of the German Heart Heart Complaints as tiredness, muscle weakness and constipation. Magnesium deficiency, in turn, can lead to symptoms such as muscle concentrations, muscle weaknesses and muscle cramps.

When should potassium and magnesium levels be controlled?

According to the experts, regular checks of potassium and magnesium concentration in the blood are particularly appropriate for cardiac arrhythmia, heart failure, kidney disease and some cardiac and hypertensive medicines to protect against possible complications, including atrial fibrillation and Life-threatening arrhythms such as ventricular fibrillation.

It is also important in the current cardiac arrhythmia to adapt the "normal high" potassium and magnesium levels (eg, to a potassium value of 4.4 mmol / l and a magnesium value of 0.9 mmol / l). In some cases the heart rhythm disorder can be eliminated, but it often has to look for other causes and treat the arrhythmia itself, explain Professor Götte.

Diet with significant influence

To compensate for the lack of potassium and magnesium, diet has already changed can make a significant contribution. Usually, the body gets enough potassium and magnesium of diet. Potassium suppliers are mainly dried dried apricots and bananas as well as vegetables such as potatoes, sprayes, peas, white beans and pulses, according to Professor Götte. Good magnesium suppliers are dry fruits, beans, phonuts, cereal products and nuts.

Causes of lack of minerals

However, according to the expert, kidney disorders, diarrhea, overuse of laxatives, vomiting, fever, and profuse sweat can all contribute significantly to the loss of potassium and magnesium. For example, in patients with heart inadequacy, a water-borne diuretic assault can accelerate the loss of electrolytes. Other factors that may contribute to the reduction in potassium and magnesium levels include summer heat, excessive alcohol consumption, diabetes and corruption diseases.

Warning of receiving magnesium without permission and potassium

Although the magnesium or potassium deficiency should be compensated for the possibility of increasing muscle and heart cells for arrhythmia, experts warn from taking potassium and magnesium supplements without medical consultation. "In principle, Professor Götte stressed that if potassium and magnesium should only be used if laboratory deficiency was found," said Professor Götte. If the standard values ​​can not be achieved through a diet that enhances magnesium and potassium, dietary supplements are only medicines that should be used, the specialist persisted.

How is the deficit corrected?

For potassium deficiency, potassium is best used as potassium chloride (40 mmol per day), and for magnesium deficiency, magnesium aspartate or magnesium citrate (10 mmol per day). Professor Götte further explains that potassium deficiency can not be compensated effectively if magnesium levels are in the normal range. Magnesium deficiency increases the symptoms of potassium deficiency.

Even high levels are harmful

The back variation – too much of both minerals – the German Heart Foundation stated that too high magnesium level was scarce, while high potassium levels were much more common. This is due to the fact that the collapse of the compressor and the heart muscle cells decreases, so that the heart is slowing. With very high levels of pneumonia, the slowdown could go so far that the heart prevents beating and heart restraint occurs.

What can lead to excessive potassium and magnesium levels?

The Heart of Germany Foundation talks about acute renal incapacity as a high concentration of potassium in the blood, as well as medications used for treating high blood pressure and heart, such as ACE inhibitors, sartans and, above all, aldosterone antagonists. Potassium stimulating diuretics may also increase potassium levels. Therefore, potassium levels and renal function should be monitored regularly in these cases. For example, diuretic levels or dialysis, potassium or magnesium levels can be reduced if life-threatening potassium and magnesium levels are present.

When taking what medication should be monitored?

According to the Heart of Germany Foundation, it is advisable to monitor the potassium levels and the function of the kidneys strongly when taking the following medicines:

  • Diuretic (dehydrated),
  • ACE inhibitors,
  • Sartane or ARNI (Valsartan / Sacubitrile),
  • aldosterone resistors,
  • diuretic stimulation of potassium (dehydration agents),
  • Digital preparations (digoxin and digitoxin).

The controls should be performed before the start of the therapy, before the dosage is changed and in the following two weeks, and then every six months. Monitoring of potassium and magnesium values ​​is particularly important for patients with heart failure. Because heart rhythm disorder can lead to exacerbation of heart failure, in the worst case to heart failure, warns the Heart of Germany Foundation. (CS)
