Magnesium and potassium: minerals for heart rhythm

Introduction: heart, electrolytes and balance of minerals

The heart is not just a pump pumping blood throughout the body. This is a complex organ, the work of which depends on electrical impulses coordinating the contraction and relaxation of the heart muscle. These electrical signals are generated and transmitted by ions, electrolytes, such as magnesium and potassium. The imbalance of these minerals can seriously disrupt the heart rhythm, leading to various arrhythmias and other cardiovascular problems. Understanding the role of magnesium and potassium in maintaining the health of the heart and awareness of ways to ensure adequate consumption of these important minerals is the key to maintaining a healthy heart rhythm and general well -being.

I. Magnesium: key mineral for the cardiovascular system

Magnesium (MG) is a vital mineral involved in more than 300 enzymatic reactions in the body. Its role in the cardiovascular system is multifaceted and critical to maintain normal heart rhythm, blood pressure and vascular function.

A. The role of magnesium in the heart function:

  1. Electric stability of the heart: Magnesium plays a decisive role in maintaining the electrical stability of the heart cells (cardiomyocytes). It regulates the movement of other ions, such as potassium, sodium and calcium, through cell membranes. These ion flows are necessary for the generation and spread of electrical impulses that control the heart rhythm. Magnesium helps prevent abnormal electrical discharges that can lead to arrhythmias.

  2. Maintaining normal heart rhythm: The low level of magnesium (hypomagnesia) is associated with an increased risk of developing various arrhythmias, including atrial fibrillation (FP), atrial flutter and ventricular tachycardia. Magnesium stabilizes cell membranes and reduces the excitability of cardiomyocytes, thereby preventing irregular heart contractions.

  3. Regulation of the contractility of the heart muscle: Magnesium is involved in the process of reduction and relaxation of the heart muscle. It competes with calcium, which is necessary for muscle contraction. Magnesium helps to relax the heart muscle after contraction, preventing its excessive contraction and fatigue.

B. Magnesium action mechanisms on the cardiovascular system:

  1. Calcium channel blocking: Magnesium acts as a natural block of calcium channels, reducing the flow of calcium in the cells of the heart and blood vessels. This leads to relaxing the smooth muscles of the vessels, a decrease in blood pressure and improve blood flow.

  2. Potassium regulation: Magnesium is necessary to maintain the normal level of potassium in cells. It promotes potassium transport into cells, which is important to maintain an electric gradient and the normal function of the nerves and muscles, including the heart. Magnesium deficiency can lead to a loss of potassium in urine and the development of hypokalemia (low potassium), which can also cause arrhythmias.

  3. Improving the function of the endothelium: Endothelium is a layer of cells lining the inner surface of blood vessels. Magnesium contributes to a healthy endothelium function, improving the production of nitrogen oxide (NO), which is a powerful vasodilator (expands blood vessels). Improving the function of the endothelium helps to reduce blood pressure and improve blood flow.

  4. Antioxidant properties: Magnesium has antioxidant properties that help protect the cells of the heart and blood vessels from damage to free radicals. Oxidative stress caused by free radicals can contribute to the development of atherosclerosis and other cardiovascular diseases.

C. The connection of magnesium deficiency with heart disease:

  1. Arrhythmias: Hypomagnium is a known risk factor for the development of various arrhythmias, including FP, atrial flutter, ventricular tachycardia and ventricular fibrillation (life -threatening condition). Magnesium deficiency increases the excitability of cardiomyocytes and contributes to the occurrence of abnormal electrical discharges.

  2. Corny heart (coronary heart disease): The low level of magnesium is associated with an increased risk of IBS, which is characterized by narrowing of the arteries that supply the heart of the heart. Magnesium deficiency contributes to the development of atherosclerosis (the formation of plaques in the arteries), increases platelet aggregation (blood cell gluing) and promotes coronary arteries spasm.

  3. Hypertension (high blood pressure): Magnesium plays an important role in regulating blood pressure. Magnesium deficiency can lead to a narrowing of blood vessels and an increase in blood pressure. Magnesium additives can help reduce blood pressure, especially in people with hypertension.

  4. Heart failure: A low level of magnesium is often found in people with heart failure, a state in which the heart cannot effectively pump blood. Magnesium deficiency can aggravate the symptoms of heart failure, such as shortness of breath, fatigue and swelling.

D. Factors contributing to the deficiency of magnesium:

  1. Insufficient consumption with food: A modern diet, rich in processed products and poor in whole products, often leads to insufficiently consumption of magnesium. Refined grains, sugar and fats contain little magnesium.

  2. Distribution of absorption: Some diseases, such as Crohn’s disease, celiac disease and malabsorption syndrome, may violate magnesium absorption in the intestines.

  3. Medicines: Some drugs, such as diuretics (diuretics), proton pump inhibitors (IPP) and some antibiotics, can increase magnesium excretion in urine and contribute to its deficiency.

  4. Chronic stress: Chronic stress can lead to increased excretion of magnesium in urine.

  5. Alcoholism: Alcohol abuse can lead to a deficiency of magnesium due to poor nutrition, violation of absorption and increased excretion in the urine.

  6. Diabetes: People with diabetes have an increased risk of magnesium deficiency due to increased excretion of magnesium in urine.

E. Diagnosis of magnesium deficiency:

Diagnosis of magnesium deficiency can be complex, since most of the magnesium in the body is inside the cells, and not in the blood. A conventional blood test for magnesium may not reflect the true level of magnesium in the body.

  1. Blood test for magnesium: This is the most common method for diagnosing magnesium deficiency. However, it can be inaccurate, especially with mild or moderate deficiency.

  2. Magnesium analysis in red blood cells (RBC): This analysis measures the level of magnesium inside red blood cells and can be more accurate than a regular blood test.

  3. Magnesium removal test: This test measures the amount of magnesium displayed in the urine within 24 hours. He can help determine whether the body loses too much magnesium.

  4. Clinical symptoms: The doctor can also take into account clinical symptoms, such as muscle cramps, fatigue, weakness, arrhythmias and high blood pressure, in the diagnosis of magnesium deficiency.

F. Methods of increasing magnesium:

  1. Diet rich in magnesium: Include products rich in magnesium in your diet, such as:

    • Dark-leaf green vegetables (spinach, cabbage)
    • Nuts and seeds (almonds, cashews, pumpkin seeds)
    • Whole grains (brown rice, oats)
    • Legumes (black beans, beans)
    • Avocado
    • Dark chocolate

  2. Magnesium additives: If the diet is not enough, you can consider the possibility of taking magnesium additives. There are various forms of magnesium additives, such as:

    • Magnesium citrate: It is well absorbed and can have a slight laxative effect.
    • Magnesium glycinate: Easily absorbed and does not cause stomach disorders.
    • Magnesium oxide: It is less well absorbed, but contains more magnesium on the dose.
    • Magnesium chloride: It is well absorbed and can be used locally.
    • Taurat Magnesium: Combines magnesium with taurin, amino acid, which is also useful for the heart.

    Before taking magnesium additives, you need to consult a doctor in order to determine a suitable dose and shape.

  3. Transdermal use of magnesium: Magnesium can also be administered through the skin using magnesium oil, epsom salt or magnesium lotions. This can be useful for people with problems of absorption of magnesium in the intestines.

II. Potassium: an important electrolyte for heart rhythm

Potassium (k) is another vital electrolyte that plays a key role in maintaining the normal function of the heart. It is necessary to maintain an electric gradient in cells, which ensures the transmission of nerve impulses and muscle contraction, including the heart muscle.

A. The role of potassium in the heart function:

  1. Regulation of electrical activity of the heart: Potassium plays a central role in the regulation of electrical activity of the heart cells. It determines the rest of the rest of the cell membrane and is involved in the depolarization and repolarization processes necessary for the generation and spread of electrical impulses.

  2. Maintaining normal heart rhythm: The normal level of potassium is necessary to maintain regular heart rhythm. Low potassium (hypokalemia) or high levels of potassium (hyperkalemia) can lead to various arrhythmias, from lungs to life -threatening.

  3. Contractibility of the heart muscle: Potassium affects the contractility of the heart muscle. Both hypokalemia and hyperkalemia can weaken the contractions of the heart and reduce its pumping function.

B. The mechanisms of potassium action on the cardiovascular system:

  1. Maintaining the cellular potential of peace: Potassium is the main intracellular ion, and sodium is the main extracellular ion. This difference in concentrations creates an electric gradient through a cell membrane, known as the potential of peace. Potassium plays a key role in maintaining this rest potential, which is necessary for the normal function of nerves and muscles.

  2. Repolarization regulation: During the electrical cycle of the heart, potassium ions come out of the cell, causing repolarization, which is the return of the cell to the potential of rest. Violation of this process can lead to arrhythmias.

  3. Influence on vascular tone: Potassium can affect the tone of blood vessels, contributing to their relaxation and decrease in blood pressure.

C. The connection of the deficiency and excess potassium with heart disease:

  1. Hypokalemia (low potassium):

    • Arrhythmias: Hypokalemia is a common cause of arrhythmias, including FP, ventricular tachycardia and ventricular fibrillation.
    • Fatigue and weakness: A low level of potassium can cause fatigue, muscle weakness and convulsions.
    • Increased blood pressure: Hypokalemia can help increase blood pressure.
    • Heart failure: A low level of potassium can aggravate the symptoms of heart failure.

  2. Hyperkalemia (high level of potassium):

    • Arrhythmias: Hyperkalemia can also cause life -threatening arrhythmias, including bradycardia (slow heart rhythm), a blockade of the heart and cardiac arrest.
    • Muscle weakness: A high level of potassium can cause muscle weakness and paralysis.
    • Nausea and vomiting: Hyperkalemia can cause nausea, vomiting and diarrhea.

D. Factors affecting potassium levels:

  1. Diet: Inadequate potassium consumption with food can lead to hypokalemia.

  2. Medicines: Some drugs, such as diuretics (especially loop and thiazide diuretics), can increase the excretion of potassium in urine and contribute to hypokalemia. Angiototenzinoproding enzyme (APF) and Angiotensin II (sconces) receptors can cause hypercalemia, especially in people with kidney disease.

  3. Kidney diseases: Kidney diseases can affect the ability of the kidneys to regulate the level of potassium in the body, leading to hypokalemia or hyperkalemia.

  4. Digestive disorders: Vomiting and diarrhea can lead to potassium loss and the development of hypokalemia.

  5. Hormonal disorders: Some hormonal disorders, such as hyperaldosteronism, can lead to hypokalemia.

  6. Insulin: Insulin helps to move potassium into cells, which can lead to hypokalemia, especially in the treatment of diabetic ketoacidosis.

E. Diagnostics of potassium level:

The level of potassium is usually measured using a blood test. It is important to inform the doctor about all drugs and additives that you take, as they can affect the results of the analysis.

F. Ways to maintain normal potassium:

  1. Diet rich in potassium: Include products rich in potassium in your diet, such as:

    • Banans
    • Avocado
    • Sweet potato
    • Spinach
    • Beans
    • Tomatoes
    • Orange juice

  2. Potassium supplements: If the diet is not enough, you can consider the possibility of taking potassium additives. There are various forms of potassium additives, such as:

    • Potassium chloride
    • Citrate Calia
    • Gluconate

    Before taking potassium additives, you need to consult a doctor to determine a suitable dose and shape. Taking too much potassium can be dangerous, especially for people with kidney diseases.

  3. Correction of drugs: If the drugs that you take affect the level of potassium, the doctor can adjust the dose or prescribe other drugs.

  4. Treatment of the underlying diseases: Treatment of the underlying diseases, such as kidney diseases or hormonal disorders, can help normalize the level of potassium.

III. The interaction of magnesium and potassium in maintaining the heart rhythm

Magnesium and potassium are synergistic to maintain a normal heart rhythm. Magnesium deficiency can lead to a loss of potassium in urine and the development of hypokalemia. Magnesium is necessary for the transport of potassium into the cells, so magnesium deficiency may comprise maintaining the normal level of potassium in the cells.

A. The influence of magnesium on potassium metabolism:

  1. Potassium channel regulation: Magnesium regulates the activity of potassium channels in cell membranes. It promotes potassium transport into cells and prevents its leakage from cells.

  2. Potassium preservation in the kidneys: Magnesium helps the kidneys to hold potassium and prevents its excessive excretion in the urine.

B. The clinical value of the joint deficiency of magnesium and potassium:

The joint deficiency of magnesium and potassium is a common occurrence, especially in people with heart disease, diabetes and kidney diseases. This deficiency can aggravate cardiac arrhythmias and other cardiovascular problems.

IV. Recommendations for maintaining an adequate level of magnesium and potassium
