Hyperdynamia of the Heart

Cardiac hyperdynamia is one of the types of pathological activity of the cardiovascular system. This means that the heart works not only to provide blood circulation, but also to perform other functions. Hyperdynamia can lead to serious consequences such as heart failure, arrhythmia and even heart attack.

Cardiac hyperdynamia is the increased functional activity of the heart in response to stress. Normal functioning of the cardiac muscle and veins involves adaptive hypertrophy and reactive activation of contractile myocytes and functioning in successive phases (contraction and relaxation phases).

Symptoms of cardiac hyperdynamia may include:

1. Feeling of a racing heart 2. Fainting or dizziness 3. Fatigue or weakness 4. Chest pain or discomfort 5. Increased blood pressure 6. Shortness of breath or feeling short of breath 7. Rapid heartbeat.

Causes of hyperdynamia can be varied, including: - Chronic diseases such as arrhythmia, coronary artery disease, hypertension, diabetes and obesity, - Physical activity that causes increased heart rate and fatigue, - Stressful situations or anxiety associated with increased adrenaline and increased heart rate contractions (tachycardia), - A disorder of the nervous system that affects the heart rhythm.

Treatment for hyperdynamia depends on the cause of its occurrence. If it is caused by chronic diseases, then medications must be taken to control the symptoms. Lifestyle changes such as reducing stress, engaging in physical activity and eating healthy are also recommended. If symptoms are caused by physical activity, you should rest and reduce the intensity of exercise. If you have a nervous system disorder, you can consult a doctor who will prescribe appropriate treatment.

It is important to remember that cardiac hyperdynamia may be accompanied by other health problems, so you should consult your doctor before starting treatment.

Cardiac hyperdynamia is a syndrome in which an enlarged heart is noted and its function is noticeably impaired. Increased myocardial contractility is associated with a decrease in myocardial resistance to potassium inactivating potentials. It develops in individuals exposed to prolonged intense psycho-emotional stress, which provokes a catecholamine surge with an increase in heart function against the background of a reduced load in the form of external factors. Also, cardiac hyperdynamics is possible in highly qualified athletes or patients with congenital hemodynamic features in the form of an increase in initial pressure in the left ventricle for a number of reasons.

**Clinical picture**. At first, patients have few complaints, which can lead to a delay in seeking medical help. Over time, the following symptoms are observed: weakness, fatigue, decreased performance, fluctuations in blood pressure with a tendency to increase, headaches with cephalgia, dizziness, and in severe cases, visual impairment may occur. In the future, it is possible to develop heart rhythm disturbances with high heart rates; tachycardia is more often detected, and arrhythmia is less common. In many of the cases
