Always feel uncomfortable with your heart? This & quot;heart health self-examination manual" can often take out and turn over
Our body is like a machine, with the growth of age, the body organs also began to gradually degenerative disease, in the clinical symptoms of each, such as bone spurs on the foot, that walking painful, eat what drugs do not relieve, such as gum atrophy, will slowly lose teeth, that if the heart is bad and what are the symptoms? And what should be done about it? Please continue to read on.
The location of the heart and its role
The heart isLocatedIn theThoracic cavity, between the diaphragm and the two lungs, about two-thirds of it is on the left side of the midline, ifYouHave taken a chest X-ray, it should be clear that the location of the heart is very obvious. The apicalPulsationCan be seen or felt at 0.5-1.0 cm medial to the left anterior chest wall. The base of the heart is wide, with large blood vessels entering and exiting from it, and is oriented toward the right posterior superiorly, adjacent to organs of the posterior mediastinum such as the esophagus.
The reason why I'm here to explain in detail the location of the heart and the alignment of the great vessels of the heart is actually related to a skill that everyone in society should learn, namelyCardiopulmonary resuscitation. In the golden hour if there is no paramedic next to you doing chest compressions, it is likely to save someone's life, I have been out to 120 and have seen many enthusiastic people doing chest compressions before the paramedics arrivedButThe compressionSite is not right, some even pressed to the right side of the chest, where I then a small science, compression site in theLower 1/3 junction of the sternum, is the location of the heart. Some of you may not know why pressing this part can save your life, because when a person has a cardiac arrest, the heart pumping function stops, then our brain and other important organs will be lack of blood and oxygen, so by exogenous pressureCan play a temporary purpose of pumping blood.
Under normal conditions, the heart pumps blood from the left ventricle into the aorta through constant contraction and diastoleAnd drives the bloodTo provide nutrients and oxygen to the brain and other parts of the body to meet metabolic needs. The right ventriclePumps venous blood into the lungs, and the lungs, through capillary blood exchange, allow oxygen-rich arterial blood to enter the heart and enter the circulation again.
TheHeartCan also secreteNatriuretic hormone, which plays an important role in maintaining the balance of water and electrolytes in the body and promoting the excretion of metabolites. If you are careful, you will find that many patients who are hospitalized for heart failure have to be repeatedly rechecked for one indicatorBNP, because this indicator is often very high in heart failure patients, and will slowly start to decline after a period of hospitalization, so this laboratory test is also an important reference toGuide clinical treatment and prognosis assessment.
What are the common symptoms of a bad heart?
In fact, this is a very broad term, because heart disease is a general term that includes many types of heart disease, which may be organic, functional, conduction, congenital, etc. Various diseases also have their own different clinical symptoms, which I will describe below for general reference only.
Some patients with atrial fibrillation will also have blackDawnWhen they have an attack, i.e., they feel black in front of their eyes and unsteady, some patients with premature beats will have fidgeting, that is, they feel uncomfortable in thePrecordialAreaAnd they cannot describe how uncomfortableThey feel.
When the pumping function of the heart is impaired:To put it bluntly, that is, the heart does not beat out as much blood as normal after each beat, then the peripheral organs do not have enough blood, there will bedizziness, weakness, reduced activity endurance, blood pressure drops, etc. If the heart fails, then blood stagnation,edema, shortness of breath, breathing difficulties, coughing pink foamy sputum, sleep at night can not lie down, etc.
③ When the myocardial ischemia: This point is actually related to the blood supply vessels (coronary arteries) around the surface of the heart, the most common is atherosclerosis, the narrowing of the blood vessels, then the lack of blood supply to the myocardium will have chest pain, if the pain will attack or intensify after the activity, with the degree of narrowing of the blood vessels further serious, may haveangina attacksat rest, if the development continues, the occlusion of blood vessels, that is If myocardial infarction occurs, then there will bepressure painin the precordial area.
④When congenital heart disease:In fact, there are many types of this, the common symptomsare frequent colds, repeated respiratory infections, susceptible to pneumonia; poor growth, wasting, excessive sweating; weak sucking during breastfeeding, feeding difficulties, or the baby refuses to eat, choking, usually shortness of breath; children complain of easy fatigue, poor physical strength; blue lips and nails or blue after crying or activity, pestle-like fingers and toes; like squatting, will havesyncope, hemoptysisand other manifestations.
Common tests for heart disease
ECG and 24-hourambulatoryECG: routinely, we can check the heart conduction, heart rate and rhythm, if not, see whether it is atrial fibrillation or premature beats, whether it is caused by atria or ventricles, which is apreliminary screening. This is an important reference test to guide clinical treatment.
●Echocardiography: It is possible to observe themorphologyof the heart, the movement of the ventricular wall, the activity of the heart valves, and the function of the left ventricle, the EF value, and the presence of congenital heart disease through ultrasound.
●Active plate exercise test: It can be used to observe the occurrence of heart rhythm during exercise to determinewhether there is a relationship between exercise and arrhythmia, and also to observe the blood supply to the heart to help diagnose coronary artery disease.
Radioisotope cardiac dynamic function tests: usually divided into three types: cardiovascular scintigraphy, cardiac functional isotope examination and myocardial isotope scan. Myocardial isotope scan can observe myocardial infarction, myocardial ischemia,reserve functionof myocardial perfusion, etc.
Catheterization and cardiovascularangiography: This is used for heart diseases that are difficult to diagnose by other diagnostic means. Currently, coronary angiography is the "gold standard" for the diagnosis of atherosclerotic heart disease. It can clarify whether there isstenosisin the coronary arteries, the location, degree and extent of stenosis, and provide a basis for treatment methods.
How to take good care of the heart?
●Lifestyle:Combine work and rest, maintain emotional stability, avoid great joy and sadness, do not disrupt the routine of life, pay attention to the work and rest time, and moderate entertainment, avoid watching TV and playing cards for a long time, avoid prolonged exertion, staying up late, anxiety, excessive mental tension, avoid strenuous activities, etc.
Diet: pay attention to low salt and low fat diet, the total salt intake should be controlled to less than 6g per day, eat more fresh fruits and vegetables, because fresh fruits and vegetables are rich in magnesium, potassium and folic acid, which can help prevent the progress of atherosclerosis and further improve the condition of hypertension; regularly monitor the heart rate, blood pressure, electrocardiogram, blood lipids, liver function, kidney function and cardiac ultrasound. If you have the common manifestations I mentioned above, it is best to go to a regular hospital cardiology department in time to improve the examination and treatment.
