How does hypertension break the heart bit by bit ? 𝐁𝐥𝐨𝐨𝐝 𝐏𝐫𝐞𝐬𝐬𝐮𝐫𝐞 𝐅𝐀𝐐

Our heart is a hollow pump whose main function is to pump fresh blood into the arterial vascular system continuously. The heart is divided into four chambers, the upper two chambers are called left atrium and right atrium respectively, and the lower two chambers are called left ventricle and right ventricle respectively. The root of arterial blood vessels is connected to the heart, and its main responsibility is to transport the blood discharged from the heart to all organs of the whole body. If the pressure in arterial blood vessels is too high, it is called hypertension. Hypertension can have adverse effects on the heart through a variety of mechanisms.

1.If the pressure in arterial blood vessels is too high, the resistance of cardiac blood drainage will increase, which will gradually cause ventricular wall hypertrophy over time. After the ventricular wall is thickened, its movement becomes dull, inflexible and uncoordinated, which affects the function of cardiac blood pump, in severe cases, heart failure may be caused by poor diastolic capacity of the Heart (term is diastolic heart failure or heart failure with preserved ejection fraction).

2.Excessive pressure in arteries can lead to increased pressure in the heart cavity, which will lead to atrial dilatation over time. Atrial dilatation is especially prone to atrial fibrillation, which is a very difficult disease and can lead to heart failure or cerebral infarction if not handled properly.

3.The most common hazard of hypertension is coronary heart disease. The pressure of blood flow in the arterial lumen increases for a long time, which can destroy the integrity of the arterial intima (it can be simply understood that there is a small rupture in the vascular intima), so cholesterol in the blood will enter the vascular wall by chance, and gradually accumulate and increase to form atherosclerotic plaque. Gradual increase of plaque will lead to obvious stenosis of coronary artery and myocardial ischemia, which is coronary heart disease. Sudden rupture of plaque in coronary artery will cause thrombosis, which will block its lumen and cannot deliver fresh blood to myocardial tissue. As a result, myocardial ischemia and necrosis are called myocardial infarction.

Whether there are symptoms or not, as long as blood pressure increases, the health of the heart will be affected by the above different ways. So we all need to prevent hypertension. Once hypertension occurs, active treatment should be taken to avoid causing harm to the heart.
