STUDY OF PSYCHOLOGICAL STRESS AND ITS IMPACT ON THE HUMAN HEART

Аннотация

Cardiovascular diseases (CVD) are currently the leading cause of death worldwide. Millions of people die or become disabled from these diseases every year. Recent epidemiological studies have shown that although CVD develops earlier in men, its incidence increases in women after menopause. This is likely due to hormonal differences, lifestyle factors, stress levels, and access to health care. The article analyzes heart diseases, their types, causes of development and symptoms. Extensive information on the risk factors of these diseases and methods of their prevention is presented. Methods of treating heart diseases, modern approaches to medicine are also presented. According to the World Health Organization (WHO), more than 18 million people die from cardiovascular diseases every year. This is approximately 32% of the total number of deaths. About 85%ofthem occur as aresult of aheart attack orstroke. Keywords: tachycardia, bradycardia, fibrillation, hypertension (high blood pressure), arrhythmia(irregular heartbeat). Introduction: The heart is one of the central organs of the human body, its continuous activity ensures the balanced functioning of all vital systems. The heart plays a key role not only as a mechanical pump. Its complex structure, consisting of muscle tissue, sensitivity to bioelectric impulses and the rhythm of vegetative regulation are the basis for recognizing it as the main one for human health. Heart dysfunction in most cases develops unnoticed, gradually and without any special clinical symptoms. Therefore, the issue of heart health should be approached not only after the disease is detected, but also at the stage of prevention. Factors affecting heart function are extensive and include such aspects as hereditary predisposition, environmental impact, psychoemotional state, nutritional status, level ofphysical activityand lifestyle. MainPart 1. Structure and Function of the Heart: The heart has four chambers: two atria (top) and two ventricles (bottom). Blood enters the heart through the veins, where it is cleaned and distributed throughout the body through the arteries. The heart is made of muscle tissue andconstantly contracts and relaxes - thisprocess is called "contraction". Clinic: Heart disease is widespread in modern life. Heart disease is often caused by poor diet, stress, a sedentary lifestyle, smoking, and alcohol consumption. Therefore, it is useful tofollowthe followingadvice. 98,7:ROTCAFTCAPMI.SECNEICSLACIDEM ,5202 ,tsuguA,5emuloV gro.srehsilbupcimedaca.www Moderate and healthy eating Engagein physical activityevery day Avoid stress and take timetorelax Quittingsmokingand harmful habits 1. Diseases:The mostcommon majordiseases . 2. Ischemic heart disease (IHD) is caused by narrowing or blockage of the blood vessels (coronary arteries) that supply oxygen andnutrients to theheart. Symptoms: 3. -Chest pain 4. -Shortness ofbreath 5. -Fatigue 6. -Heart rhythm disturbances 7. If this conditioncontinues, a heart attack, thedeath ofthe heart muscle, can occur. Heartattack (myocardial infarction) If blood flow to the heart muscle is suddenly stopped, the heart tissue is deprived of oxygen anddies. Symptoms: ..Severechest pain(on theleft side, spreading to theneck, shoulder orarm. -Coldsweat -Shortness ofbreath orfainting may occur.. 3. Heart failure: When the heart is unable to pump enough blood throughout the body, it is called heart failure. Symptoms: ..Shortnessof breath, especially when lying down. -Swellingof thelegs. -Fatigue -Rapid heartbeat Heart rhythm disturbances. Severe stress can disrupt the normal rhythm of the heart, causing arrhythmia, orirregular heartbeat. Sometimes these conditions can feel likethe heart has stopped or is beating too fast. This is especially dangerous for people with heart disease. Chronic stress can lead to high blood pressure, which can cause the heart muscle to thicken. 98,7:ROTCAFTCAPMI.SECNEICSLACIDEM ,5202 ,tsuguA,5emuloV gro.srehsilbupcimedaca.www As a result, the heart does not receive enough oxygen, increasing the risk of heart attack and stroke. Diseases caused by stress: Hypertension—high bloodpressure. Arrhythmia—irregular heartbeat. Coronary—heart disease. Statistics---According to the World Health Organization (WHO), cardiovascular diseases causethe death ofmore than 17million people every year. Arrhythmia (irregularheartbeat) Theheart can beat too fast or tooslowand irregularly. There are different types: -tachycardia—the heart beats toofast -bradycardia—theheart beats too slow -fibrillation—theheart beats irregularly, as ifquivering. Theseconditions disrupt theheart's function andcan lead tofainting or even cardiac arrest. Hypertension (high blood pressure). When blood vessels are constantly under high pressure, the heart works harder and this tires the heart. If it continues for a long time, the risk of heart attack or stroke increases. In modern life, people are constantly exposed to various psychological pressures - stress. Althou
