What are the symptoms of left ventricular hypertrophy?
| The number of people suffering from various major diseases in modern life has increased dramatically, which has had a great impact on the lives of many people and has also put great pressure on public medical resources. For example, heart disease is a disease with a high incidence and serious harm. There are many types of heart disease, among which ventricular hypertrophy is relatively common. Let’s take a look at the symptoms of left ventricular hypertrophy. The left ventricle receives oxygenated blood from the left atrium and pumps it into the aorta to supply the oxygenated blood to the whole body. Along the way, oxygenated blood passes through two valves, one is the mitral valve between the left atrium and left ventricle, and the other is the aortic valve located in the aorta, both of which are used to prevent blood from flowing back. Compared to the right ventricle, the left ventricle is longer and more conical in shape. Its cross section also presents an elliptical or nearly circular outline. The sternocostal surface, which is the front of the heart, is mainly composed of the right ventricle, and a small part is also composed of the left ventricle. However, the left ventricle not only makes up the apex of the heart, but also makes up most of the septal surface of the heart, which is the side of the organ that meets the diaphragm. In order to pump blood at a high blood pressure, the muscle of the left ventricle is thicker and more developed than that of the right ventricle. (1) When the left ventricle is in the stage of compensatory hypertrophy, there may be no clinical manifestations, and the blood pressure is usually high at this time; (2) When the left ventricle is in the stage of decompensated enlargement or certain myocardial damage directly leads to left ventricular enlargement, there will be the following clinical symptoms: 1) Fatigue and weakness after slight activity or fatigue even when resting, indicating that the left ventricular ejection cannot meet the body's needs; 2) Chest tightness: When the left ventricle cannot eject blood in time, pulmonary blood return is obstructed, and chest tightness will occur, which worsens after activity; 3) Blood pressure changes: Blood pressure has dropped significantly compared to before and may even become hypotension, indicating a sharp decrease in left ventricular ejection volume; 4) Cardiac manifestations: increased heart rate, arrhythmia, and chest pain during myocardial ischemia; 5) Heart failure manifestations: further aggravation, heart failure manifestations such as orthopnea at night and edema of both lower limbs will occur. |
